Zucchini and Cheddar Frittata

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.

Great way to use zucchini Fluffy and delicious.
Question can I use part eggs and part egg whites??
Sure, Cheryl, that will work. Enjoy!
Beautiful, sweet lovely frittata!! Best I’ve ever had.
This was delicious. I have SO MUCH zucchini in my garden – I will definitely be making this again. I’d love to add a crust and try it as a quiche.
I made this frittata today for Father’s Day and it was a hit. It took an extra four minutes in the oven – it was just perfect. I love not cooking the eggs on the stove top before putting in the oven like other frittata recipes I have made. Delish!
This looks amazing but half my family can’t eat dairy.
What product would you use to exchange the heavy cream for something non dairy?
I know what cheese I would use but could use some advice for the cream.
Hi Andrea, Thanks for your note. For a non-dairy option, some readers have commented that they’ve used Rich’s non-dairy coffee creamer (frozen) and Trader Joe’s unflavored non-dairy creamer. (Please keep in mind that I haven’t tried either of these.) I hope that helps! 🙂
I’ve never had a frittata before this one and I’m saving this recipe- delicious. I took a tip from another commenter and doubled it and cooked it in a 12” cast iron skillet. I cooked it for 35 minutes. Thank you
So Delicious and so so EASY to make. Thank you Jenn for another winning recipe. We love so many of your recipes and we know that anyone we try will turn out to be a winner. I have three children, so mealtimes can be challenging. This recipe is easy to whip together for any meal of the day and it is a crowd pleaser. We live in Toronto, Canada so I used half and half instead of the heavy cream and used medium cheddar – turned out amazing. I always wanted to try this recipe but thought it would not turn out quite right when I make it. Well, was I wrong, so for all of you wanting to try it – go for it – it is easy and fast and so delicious.
Jenn – if I wanted to use 9 eggs instead of 6 in a 10 inch nonstick pan – how would you adjust the recipe?
Hi Annie, So glad you enjoyed it! For 9 eggs, I’d increase all the other ingredients by 1/3. You may need to increase the baking time by a few minutes. Enjoy!
This reply looks like it applies to the earlier version of your recipe. I’ve not seen it but based on your response to the person who asked, it must have been 6 eggs originally.
That’s correct – I tweaked the recipe about a year ago to make a larger frittata. Hope you didn’t find that comment confusing!
This recipe is terrific. I altered some of the ingredients due to what was in-house: added 1/2 red pepper diced, substituted smoked Gouda in place of the cheddar, and substituted red onion for the shallot. I really squeezed out the zucchini prior to sautéing. Excellent!!
This was awesome! I substituted plain full fat Greek yogurt for cream.
This is amazing. A beautiful presentation for any meal. A few changes-supplemented 2% Greek yogurt and a tbs of Mayo for richness in lieu of heavy cream. Also used red onion and diced jalapeño. Oh my. Hubby loves loves loves. ❤️
Made with Gruyère Cheese instead of Cheddar Cheese and the family loved it. Another amazing recipe Jenn.
