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


  • 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
  • ¼ cup finely grated Gruyère
  • 1¼ cups heavy cream, at room temperature


  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, ¾ teaspoon salt, and ¼ teaspoon pepper. Spread the sprouts evenly in the dish and roast, tossing once halfway through, until tender and browned in spots, 25 to 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 ⅛ 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 ¼ 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 to 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 to 15 minutes.

  • Hi Jen
    I know you said this dish could be made ahead but if I make it on Thursday will it be great for Saturday? Should I freeze it?
    Thanks again!

    • Hi Jen, This is not a great candidate for freezing. I think you can get away with making it on Thursday but wouldn’t push it any longer. Enjoy!

  • Made for Thanksgiving and it turned out lovely. I brought it to a dinner, so I made it 2 hours in advance and reheated right before serving and it was still good. I wouldn’t change anything.

  • I made this for Thanksgiving thinking that I would be the only one eating it. I LOVE Brussel Sprouts and did not think it would be a “crowd” pleaser. This recipe was the HIT of the party and EVERYONE asked me for the recipe! I roasted the sprouts the day before. I took a hint from someone else and made the bread crumbs from English muffins. The only thing I changed was that I added 1 cup of the gruyere instead of 1/4 cup. Thank you!!!

  • Is there a trick to the bread crumbs from 3 slices of bread? Would removing the crust, chopping, and putting in a blender work? Thanks!

    • Just tear by hand. Takes 2 minutes. Doesn’t have to be perfect as it all blends in.

  • I’ve made this before and it’s a huge hit! I’ve always made it as written, but can I get away with Panko breadcrumbs? I don’t have any white bread and I am trying to avoid a trip to the store.

    • Hi Tiffany, I don’t think panko has enough heft for this — I worry that it will sink into the crevices and get absorbed by the cream. Sorry!

    • Hi Robert, You could definitely use a gluten-free bread. It will still be good without the topping, but I think it’s better with a little crunch.

  • I would like to double the recipe. Does everything need to be doubled since It will be made in a deep 9×13 ceramic pan or just the cream and butter?

  • *1 cup coarse fresh bread crumbs, from about 3 slices white sandwich bread, crusts removed

    So, rookie here: how do you make bread crumbs from white bread? Do you just tear it apart? Is there baking involved?
    You’ve got instructions for making croutons on the site, but not bread crumbs. I really want to try this recipe.

    • There’s no baking involved; for cornbread crumbs, you can just tear the bread into small pieces. Hope you enjoy! 🙂

  • So good. My new favorite way to prepare Brussels Sprouts. I just ate it by itself for dinner and had a second helping and decided to keep the fish I meant to eat with it for tomorrow, it was that good.

  • This was a big hit at Christmas dinner. Everyone loved it and even my mother-in-law had seconds, though she normally hates brussel sprouts. The best part was how simple and easy it was to make.

  • This was served for Thanksgiving at a friends house and we all loved it! I did not make it but definitely plan to. She added more butter and cheese. Not sure if the additions were necessary so will make as printed my first time.

  • I made this for the first time for Thanksgiving. I fell asleep reviewing my meal (that’s what I do…) and decided this was absolutely the best thing I served—and it was ALL really good! In the morning one of my guests said she woke up thinking about how delicious this was and decided it was her favorite part of the meal! She is an avowed Brussels Sprouts hater—I had to talk her into trying it! I do wish there was a way to cut the calories. My mom used to sub evaporated milk for part of the cream in some recipes. Do you think that would work here?

    • Glad that this was a hit with your guests! While I’ve never tried it, I do think you could get away with using evaporated milk for some of the cream. It won’t taste as rich, but it will still be good.

  • I made this for the Thanksgiving meal this year. Among all the Thanksgiving dishes, this one got the most praise! It’s easy to make once you have all the ingredients ready. What I love the most is that it can be made ahead of time, so it won’t fight for the oven space before a big holiday meal.

    • I made this tonight. It was delicious! I made it with gluten free bread which I chopped into bread crumbs and used cheddar cheese. We loved it! I make several of your recipes quite often and they are always a huge hit. Thank you!!!

  • Super idea for a holiday dish. I made it exactly as written for the first time on Thanksgiving. Very easy to make, well-written/reliable recipe and quite tasty. I liked the gratin very much, but my family were not fans, quite honestly. I had half the dish left over at the end of the meal. My golden retriever and I will finish it. Maybe he likes it, because I didn’t tell him they were Brussels sprouts. Hahaha! Nevertheless, there are tons of great recipes on this site that my family all appreciate and rank highly, so I will keep at it.

  • Hey Jen what is a good substitute for the gruyere cheese in this recipe? I prefer gruyere but it’s not always easy to find where I live.
    Thanks, Staci

    • Hi Staci, You can use Comte or Beaufort cheese. Cheddar would also work if it’s one that melts well (or you could eliminate the cheese). Please LMK how it comes out!
