brussels sprouts gratin

This Brussels sprouts gratin is a family favorite, and it’s perfect for the holidays because it can be made mostly ahead of time. It’s easy, too: Unlike most vegetable gratins, which are made with a béchamel sauce, this one is made much more simply with heavy cream. If you’re preparing this dish in advance, note that it requires 10 to15 minutes in the oven to warm through and crisp the topping before serving, so plan accordingly.

This comforting Brussels sprouts gratin with a crispy, cheesy topping is a holiday favorite — and you can make it ahead of time!

Servings: 6-8
Prep Time: 15 Minutes
Cook Time: 45 Minutes
Total Time: 1 Hour

Ingredients

  • 2 pounds Brussels sprouts, stem ends trimmed and cut in half through the stem end
  • 3 tablespoons unsalted butter, melted
  • Salt
  • Freshly ground black pepper
  • 1 cup coarse fresh bread crumbs, from about 3 slices white sandwich bread, crusts removed
  • 1/4 cup finely grated Gruyère
  • 1-1/4 cups heavy cream, at room temperature

Instructions

  1. Heat the oven to 425°F. Put the Brussels sprouts in a 9x13-inch ceramic or metal baking dish, and toss with 2 tablespoons of the melted butter, 3/4 teaspoon salt, and 1/4 teaspoon pepper. Spread the sprouts evenly in the dish and roast, tossing once halfway through, until tender and browned in spots, 25-30 minutes.
  2. While the sprouts roast, place the bread crumbs in a medium bowl. Pour the remaining tablespoon of melted butter over the crumbs and sprinkle with 1/8 teaspoon salt. Mix in the Gruyère. Set aside.
  3. When the sprouts are tender and browned, pour the cream evenly over the sprouts and sprinkle with 1/4 teaspoon salt. Continue baking until the cream has thickened to a saucy consistency, about 10 minutes. Remove the pan from the oven. Set the oven to broil and position a rack to 6 inches below the broiler. Sprinkle on the bread crumb mixture. Broil the gratin until the crust is golden brown, 3-5 minutes (keep a close eye on it so it doesn't burn).
  4. Make ahead tip: This recipe can be prepared a day ahead of time. Reheat in a 350°F oven, uncovered, until warm throughout and crisp on top, 10-15 minutes.

  • This recipe has become my favorite part of Thanksgiving dinner! If Brussel sprouts aren’t your favorite, you really should try this recipe. They get caramelized when roasted, the cream really creates a delicious sauce, and the gruyere breadcrumb topping is perfect to tie it together. This recipe is hands-down my favorite side!

  • There are NEVER any manners left when I serve these! My family and guests have dueled over the last spoonful!! These are beyond delicious. I add a little cayenne to the cream before pouring it over and often will use panko tossed in melted butter just to save time. Excellent recipe!

  • This is a new family favorite! I have had such success with recipes on this site, and this is one is no different. Also so easy! I was looking for something that didn’t require a lot of effort, and this more delivered. Everybody thought it was so fancy and must have taken a lot of time, so I let them think that because it sure looked and tasted that way! Even Brussels sprouts haters loved this dish – I cannot say enough about how good it is.

  • Can I use panko crumbs instead of bread?

    • — Andi on December 3, 2020

    • Hi Andi, I’m sorry but I don’t think panko has enough heft for this dish — I worry that it will sink into the crevices and get absorbed by the cream.

    Do you think I could make this a day ahead and toast the bread separately? Concerned that the topping will become soggy in the fridge. Thanks

    • Hi Andrea, For best results, I’d bake the dish up until the point of adding the topping and then refrigerate overnight. When ready to serve, add the topping and finish cooking before serving. Hope that helps!

  • I’ve made this gratin many times, but the last time I did, the cold heavy cream caused my Pyrex casserole dish to fracture on the bottom, making a huge mess in the oven. I would recommend noting the heavy cream to be room temperature. Otherwise, everything is fabulous as usual!

  • I made this dish for Christmas dinner. When Jenn says to pay attention to this dish when it’s under the broiler, she means it: the recipe advises to put it under for 3-5 minutes, but within 2 minutes the top was black and my kitchen was full of smoke.

    Luckily, only the top was burnt and I had opted to make it ahead of time. After 30 minutes of meticulously scooping the blackened crust off the top, I was pleased to find the bottom in-tact and tasty. I remade half the crust (only the top layer was burnt), moved the oven rack down a notch, and tossed the dish back in for 1.5 minutes before it was done. If I ever make this again, I’ll set the broiler to Low instead of High.

    Making this recipe as per instructions, I felt that there was too much crust. However, bear in mind that I was forced to eyeball how much crust to replace. This recipe was tasty, but I feel it could be improved by setting your broiler to low in favour of not going through what I did, hahaha.

    The short version: tasty veg dish; a little too crusty on the outside; mind the instructions’ recommendations to watch your dish under the broiler while ignoring the time recommendation of 3-5 minutes–instead, check about every 30 seconds.

  • I’d like to make this but my other foods cook at 400 degrees, not 425. Could I cook it at 400? If so how long?
    Or cook it at 425 initially and then lower to 400 when I add the cream? Then how long?
    Thanks for your help!

  • Made these this Thanksgiving and it was the star of the meal. I am also going to make it for Christmas. I bought the 2 lbs of sprouts but after I cut them and the loose leaves fell off, it was decreased quite a bit. Would you recommend buying 2 1/2 – 3 lbs for the same size pan? Thank you!

    • Hi Diana, So glad this was a hit! It’s not necessary to increase the amount of Brussels sprouts you buy. (I’ve already accounted for the trimming and the leaves falling off in the recipe.)

  • I made this recipe for our Thanksgiving Dinner. It was very easy, and I prepared it in the morning. Everyone loved it! (And you were right, Jenn; I made fresh breadcrumbs, rather than canned, and they were nice and crunchy.)

    I would definitely make this again.

  • Made this yesterday as one of our Thanksgiving sides. The only change I made was to use multigrain bread for the bread crumbs. The dish turned out to be a major hit. Will definitely make this again.

    I also made your Creamy Make-Ahead Mashed Potatoes, which is always a big hit and is now the ONLY recipe I use for mashed potatoes.

  • This is an excellent recipe. It’s even good cold! Other recipes use three times as much cheese or other over-the-top high-fat ingredients, but I agree that’s not necessary with this dish. I imagine I’ll be making this every Thanksgiving for many years to come. Thanks, Jenn!

  • Hi Jen – I was hoping to bring this dish to Thanksgiving, but the host hates all types of cheese. Do you think it will still work if I omit the cheese entirely? Also, can I bake it at home and then serve it room temperature at her house? I probably won’t get any oven time. Thanks – your recipes really are the best!

    • Hi Meg, I think you could get away with omitting the cheese but you may need to season the dish with a pinch more salt. And while I think this is definitely better hot, it would be OK to serve it at room temperature. Hope you enjoy!

  • Hi Jen! I am making this for the first time for dinner guests tomorrow (I also want to try it, since I hope to serve it on Thanksgiving!). I was hoping to make it today and reheat it tomorrow, to save myself time after work. The directions are to reheat at 350 for 10-15 minutes. However, I am also making your baked salmon with honey mustard/panko and curried roasted carrots, both of which call for a high oven temp of 425/450. Would it be ok to reheat it at a high temperature? Or should I just try to bake it all at the same time, without making it at all today? Sharing the oven for foods with various temperatures always confuses me.

    Thanks for always helping out! Love your cookbook and recipes!

    • Hi Karen, sorry if I’m responding to this too late to be beneficial! If it’s still helpful, yes, you could reheat the Brussels sprouts in the same oven as the salmon and carrots but they will take less time to heat through. Also, I’d cover them with foil for the first part of reheating and then uncover them for the last few minutes so the topping can crisp up a bit. Hope that helps! 🙂

  • Wow! I am always trying new Brussels sprout recipes trying to find the perfect one. After making this and having the leftovers, I have found my ‘best’ Brussels sprout recipe. This was awesome and received reviews from our guests. I have already bought more sprouts to make another one for Christmas. I am fairly new to this website but so far everything I have tried is a hit with everyone. Thank you!
