Zucchini and Cheddar Frittata
This post may contain affiliate links. Read my full disclosure policy.
Filled with heaps of shredded zucchini and extra-sharp cheddar, this zucchini frittata is good for brunch, dinner, or anytime in between.
I always love the idea of a frittata. Within 30 minutes, you can whip up a meal that makes good use of any leftover veggies, meat, or hunks of cheese hiding out in the fridge. But for all their perks, frittatas can often be a bit “meh” — for the same calories, give me a slice of quiche any day! This zucchini frittata, however, is what a frittata should be: packed with flavor, creamy, and delicate, almost like a crustless quiche. There are three secrets to success: 1) squeeze as much water as possible out of the zucchini; 2) add some heavy cream and lots of cheese to the egg mixture; and 3) bake the frittata in a low-temperature oven, instead of the traditional stovetop-to-broiler method, so the eggs cook gently into a custard without scrambling.
Ingredients For zucchini frittata
Step-by-Step Instructions
Begin by grating the zucchini by hand or in a food processor. It’s best to use small zucchini, as they contain less water. 
Once grated, place the zucchini on several layers of paper towels and squeeze out as much water as possible. Depending on how much water is in the zucchini, you may need to repeat this step.
Next, melt a few tablespoons of butter in a 10-inch cast iron or oven-proof nonstick pan.
Add the shallots, zucchini, and 1/2 teaspoon salt.
Cook for 7 to 8 minutes, until the zucchini is tender and cooked down.
Meanwhile, combine the eggs, remaining salt, pepper and heavy cream in a large bowl.
Whisk to combine.
Add the cooked zucchini and grated cheese to the egg mixture and stir.
Pour the frittata mixture back into the pan.
Bake for about 25 to 30 minutes, or until just set.
Serve the frittata warm or room temperature.

Zucchini & Cheddar Frittata
Filled with heaps of shredded zucchini and extra-sharp cheddar, this zucchini frittata is good for brunch, dinner, or anytime in between.
Ingredients
- 1 pound zucchini (about 2 small zucchini)
- 3 tablespoons unsalted butter
- ⅓ cup finely chopped shallots, from 1-2 shallots
- Salt and freshly ground black pepper
- 8 large eggs
- ⅓ cup heavy cream
- 1¼ cup (5 oz) shredded Cheddar cheese
Instructions
- Preheat the oven to 325°F.
- Using a food processor or box grater, grate the zucchini. Place the grated zucchini on top of several layers of paper towels and wring dry. If necessary, repeat 1 to 2 times to remove any excess moisture.
- In a 10-inch cast iron or ovenproof nonstick skillet, melt the butter over medium heat. Add the shallot, zucchini, and ½ teaspoon salt; cook, stirring occasionally, until the moisture evaporates and the zucchini is tender, 7 to 8 minutes.
- Meanwhile, in a medium bowl, whisk together the eggs, heavy cream, a heaping ¼ teaspoon salt, and ¼ teaspoon pepper.
- Add the cooked zucchini and grated cheese to the egg mixture and stir to combine. Pour the frittata mixture into the pan (no need to wash it), then place in the oven and bake until set, 25 to 30 minutes. Immediately place a dish towel or oven mitt over the pan handle after you remove it from the oven; it's easy to forget that it's hot and burn your hand.
- Freezer-Friendly Instructions: The cooked frittata can be frozen for up to 3 months. Remove the frittata from the freezer about 24 hours prior to serving and reheat it in the microwave or, covered with foil, in a 300°F oven until hot in the center.

This was fantastic. First recipe I’ve made from this site and I will definitely come back for more.
I had to wing it in some ways with the ingredients on hand and it still came out perfectly. I had two large zucchinis, which did not seem like too much, and squeezed them in a dish towel. No heavy cream so I used oat milk creamer. And I used a sweet onion instead of a shallot. Also I cooked it in a cast-iron pan. It was fantastic! My only complaint is that there wasn’t more of it. 🙂 Will double the recipe next time.
Amazingly easy and oh so yummy. I am not a very good cook, but I made this for dinner and it turned out exactly like Jenn’s pictures. That NEVER happens! It was so light & fluffy. The only change I made was I used red onion since my grocery didn’t have any shallots. My husband liked it so much he went back for thirds. I’ve already bought more zucchini to make it again.
Made this today and it was big hit! Will definitely make again. Going to try the zucchini fritters for guest this weekend.
This was delicious! My husband said it was excellent!
Made this for the first time today and it will definitely stay in our weekend breakfast rotation. My almost 3 yo( who is very very picky!!!) called this “ delicious egg pizza”. I went with it and he ate his whole serving!!! Also my 6yo devoured it before his fruit, bacon and toast lol. Two thumbs up from the whole family. Nothing brings me more satisfaction than cooking a meal that the whole family enjoys, thank you!!!
A couple of changes I made- didn’t have heavy cream but used creme fraiche instead and thinned it out with some whole milk. Also, added a tbsp of fresh basil to the egg mixture and used gruyere cheese instead bc it’s what I had in the fridge 😉
Delicious! I mixed this up in the morning, stuck in refrigerator until dinner. Baked in 9” nonstick cake pan. Put under broiler for five minutes – watching carefully. Would definitely make this again!
I believe I have reviewed this in the past, but it really deserves and encore. We have made a lot of frittatas over the years, but this one stands out above all of them. It really does have a quiche-like texture and the leftovers are fabulous!
Fantastic recipe— don’t usually follow recipes for frittatas, usually use up whatever vegetables I find in the fridge, add eggs and cheese on top, cook it in the pan and broil it to finish the top, but it was worth following this to snap out of the routine. This is a restaurant-like frittata and using butter and shallots and cooking it in the oven really gives a sophisticated result. I had no cream so I used whole milk, same quantity as the cream. Thanks Jen for livening up my week day lunches!
Just made it tonight and it was fantastic. As another reviewer mentioned, I rolled the shredded zucchini in a clean dish towel and that did the trick. I didn’t have heavy cream so I combined 1 tbsp of mayo with some half and half to make it thick and substituted another tbsp of mayo for one egg. I had a previous zuke recipe that used a mayo/eggs combo and for some reason it gives it an extra zing. I also sprinkled a little less than a 1/4 c of Progresso Italian breadcrumbs on top but that adds about 25 calories to each serving so just be aware of that.
Can I prep all the ingredients and bake in a pie plate, rather than the pan?
Thx
Sure, that should work. Enjoy!
Can I bake the day before and then reheat the next morning? Suggested time and temp for reheat?
TIA
Hi Judy, that’s fine. You could either reheat it in the microwave (that’s probably what I’d do) or in the oven. If you reheat it in the oven, I’d cover it with foil and put it in a 325-degree oven for 20 minutes or until heated through. Hope you enjoy!
This recipe was so good but it was very rich. I made some changes to my recipe and it was still really nice and cooked perfectly! I did zucchini and broccoli with cheddar jack because that’s what I had. I think no matter how you changed the veggies or cheese it would be delicious. Next time I will use much less butter and cheese and less heavy cream to save some calories and make it less rich.
Planning to make this for a special brunch…will it work in a regular all-Clad sauté pan that isn’t non-stick?
Hi S, I wouldn’t recommend it – I think it would stick. Sorry!
My husband and son both declared this to be “perfect.” Followed the recipe measurements precisely but used plain Greek yogurt thinned with a little 2% milk because we didn’t have cream in the house.
Love this as a frittata inspiration! We’ve made this as is with zucchini, but also have added kale or spinach, or sliced asparagus with goat cheese. Truly a lovely frittata – it reheats well.
This recipe is so easy and so delicious. Love the creaminess (although I used whole milk and a swiss/gruyere shredded cheese blend since I didn’t have heavy cream or cheddar cheese.) Will have to try it again with cheddar and other customizations! I just squeeze the zucchini out with my bare (clean) hands over a strainer set into a large bowl. A little messy but I have no dish towel to wash!
Thank you Jenn.
I made this with one zucchini and leftovers of a zucchini summer squash vegetable saute, it was excellent, very good flavor! Will definitely make again!
This is absolutely delicious. Just a few ingredients and so much flavor. I will make this again! Thanks for another fantastic recipe!
Excellent recipe! Made it for Mother’s Day Brunch and everyone loved it! When my mother in law who is an amazing cook likes what I make, I know it’s a winner!
I was planning to use frozen shredded zucchini so I know there will be a lot more liquid than if it was fresh, should I be still trying to squeeze out as much liquid as possible?
Yep — hope you enjoy!
Would a 9 inch cast iron skillet work for this?
Yep – hope you enjoy!
Once again, as always, I was impressed by this recipe. It was perfect! Tender, not rubbery or runny, with great flavor. Every single recipe that I’ve made of ours is a perfect, five-star dish. By nature I am skeptical and would have been tempted to believe that you were fiddling with the statistics to bump up the scores, if I didn’t know better. It is obvious that your skills as a professional chef, as well as tinkering with a recipe until it is just right is paying off. I don’t believe there is another site with so many excellent recipes and five-star ratings. Thank you!!! I know that I can try anything you post and don’t ever have to worry about being disappointed.
Hi Jenn, I love your zucchini frittata recipe. I’ve made it many times. I have around 8 oz of ham heron a ham steak) in the freezer that I want to use up and would like to include it in an egg dish. (BTW… we rarely eat ham but my husband wanted to make a navy bean and ham soup).
I’m leery of some of the other frittata recipes out there as I really like the way yours turn out. I haven’t made the spinach version yet but will at some point.
Suggestions on using the ham with or without veggies in one of your frittatas would be welcome.
I continue to be a big fan and make one or more of your recipes a week!
No hurry. Thanks in advance! Susan 😊
Hi Susan, I think the ham steak would be delicious chopped up and added to either my zucchini or spinach frittata. You could also add it to these egg bites instead of the bacon.
This was the best frittata I have ever made, Jenn! Absolutely perfect. I’m sorry I did not take a photo, but we devoured it in no time at all. I used goat’s cheese instead of cheddar. I am going to share it on my website, naturally, I shall be acknowledging you. Deborah Garber (www.deborahgarber.live)
This is my first time making a frittata and your recipe was perfect and delicious! Cheddar cheese and zucchini are two of my favorite ingredients on the planet, thank you for creating a fabulous recipe!
I love this Frittata. It’s easy enough to throw together for a week day breakfast. I do all of the hand on prep and cook the zucchini, pop it in the oven. By the time I have the kids up and dressed its ready for breakfast! (well for 3/5 of the family, 2 kids are picky and they get cereal lol) It makes enough that we have leftovers for the next day.
Made this last night and my youngest who doesn’t like eggs had two slices. I forgot to buy courgettes so used bacon lardons instead and fried in a pan and browned under the grill. Was lovely and a triumph to see my daughter eat eggs.
Love this recipe! Easy and delicious. A great way to use up those garden zucchinis
Delicious! The zucchini really adds to the dish. I also add in a little diced Canadian bacon for extra protein.
This was super easy to make and very tasty! I followed it exactly. Will definitely make again!
I’m going to try this recipe this weekend. I have always been disappointed with the texture of my frittatas. Tip for squeezing liquid out of zucchinis…I use an old cotton kitchen dish towel. You can really squeeze the zucchini. I find that paper towels can get wet and stick to the zucchini. Sometimes I press the balled up towel against a strainer for more leverage.
Thanks for another great recipe (I’ve got them all bookmarked!). I make this frequently, it’s moist, tasty and delicate, just perfect for brunch or lunch. I usually have garlic cloves on hand instead of shallots, plus I dust it with smoked paprika and black pepper before baking. I don’t miss the quiche crust at all, frittata is the way to go with a recipe like this one!
I loved this recipe, not only because it tasted delicious, but because it was gluten free and lower in carbs. Thanks so much!
This is a wonderful recipe which we have for dinner often. My husband loves it and normally does not like zucchini. I also add chopped sweet peppers to the sauté and grated hot pepper cheese. Also whole milk can be subbed for heavy cream and it still turns out well. Thank you Jen!
This frittata is so good. It is easy to prepare. I have made it several times.
Great frittata
Summer garden zucchini really is showcased in this super easy and delicious frittata. (Of course using zucchini when it’s not in season always works too.) My husband is usually the frittata chef in our house and never thought to use the cast iron skillet to sauté the zukes first, assemble then to pop it in the oven to bake. Moist and scrumptious. Have made it many times and will continue to do so!
Being a vegetarian and my husband a meat eater I have found many recipes on your site that we both love!
They are tasty, simple to make and healthy. This is my #1 go to site when I am looking for new recipes.
This is one of our favorite ways to use up extra zucchini in the summer. Makes a delicious, easy dinner with a green salad and maybe some fried potatoes on the side.
Has become a staple in my house for Sunday breakfast. Delicious and easy to make!
A great recipe for Keto! We have zucchini in the garden, a nice way to use them. It was really delicious, thank you!
I had some frozen zucchini spirals and thought this would be a great way to use them. This recipe is so easy and it’s such an easy way to make eggs. It was delicious!!! I didn’t have shallots but white onion was just as good.
Excellent recipe. Glad to have found it. I had some heavy cream that was well past its “best by” date but not sour, so I needed a recipe that called for heavy cream. I added both shallots and purple green onion bulbs (from our CSA produce box) and used medium yellow cheddar. The results were excellent, and made for a delicious late lunch when served with a side of spaghetti with olive oil, black pepper, and pecorino.
Do I need to peel the zucchini or just grate the whole thing?
Thnx
You can just grate the whole zucchini. Hope you enjoy!
Turned out perfectly. I made this exactly as written. Wouldn’t change a thing. Definitely keeping this recipe to use again and again.
Such a great recipe! Thank you for sharing!
Hi!
How is 3 oz shredded cheese equal to 1 cup? Aren’t there 8 oz in 1 cup? Can you clarify? Cooking tonight…
Thanks!
Hi Bella, if you were to weigh the cheese, it would be the equivalent of 3 ounces. 8 ounces in a measuring cup refers to volume. Hope that clarifies and that you enjoy the frittata!
I made a version of this last week. It was delicious and really easy. I added leftover cherry tomatoes that I had roasted – and that added great flavor. I substituted a combination of swiss and mozzarella cheese for the cheddar since that’s what I had on hand. My cooking time was closer to 35 minutes but that’s likely due to a difference in pan size
I’d love to add some broccoli into this as well. Would it be best to steam the broccoli first before baking the frittata? I like my broccoli to be very soft. Also, do you get the zucchini before shredding it?
That was meant to say ‘gut’ as in, taking all the seeds out.
Hi Ashley, Yes I’d cook the broccoli first, but make sure it is dry before adding it. And no I don’t take the seeds out of the zucchini. Hope you enjoy! 🙂
I have made this a few times now. Such a lite dish and a means of using up zucchini. I have added in sautéed fresh mushrooms. Excellent recipe!
This frittata is wonderful. I followed it to the letter. The only problem I had was not having an oven-proof skillet. When I got to the step to put it in the oven I used a ceramic pie plate (exactly like yours in the summer strawberry cake recipe). I almost always use white cheddar, but I only had the light orange kind. Well, the presentation was beautiful – between the red ceramic, ivory interior, and colorful cheddar, it looked magazine-worthy. The taste couldn’t be better. Thank you so much for your PERFECT recipes!!
Made this as written for the most part with some minor substitutions and additions below, and my roommate loved it!
1. used a cast iron skillet since that was the only oven proof skillet I had
2. used onions instead of scallions since I didn’t have any of the latter
3. added chopped bits of cooked bacon, and also cooked the onions and zucchini in a little bit of reserved bacon fat in addition to the butter
4. Added thin slice of tomato on top just before popping it in the oven
Just like Jen said it would, turned out with just set outer browned edges, and still custardy in the middle. Yum!
Excellent recipe – comes together quickly and with a salad, the perfect summer meal.
