This comforting Brussels sprouts gratin with a crispy, cheesy topping is a holiday favorite—and the best part? You can make it ahead of time!
This Brussels sprouts gratin is a family favorite, and it’s a perfect holiday dish because you can make most of it ahead of time. Best of all, it’s super simple! Instead of fussing with a béchamel sauce like most gratins, this one uses heavy cream to keep things easy. If you’re prepping it in advance, just remember it’ll need 10 to 15 minutes in the oven before serving to warm through and crisp up that golden topping—so plan accordingly.

This comforting Brussels sprouts gratin with a crispy, cheesy topping is a holiday favorite—and the best part? You can make it ahead of time!
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
- ¼ cup finely grated Gruyère
- 1¼ cups heavy cream, at room temperature
Instructions
- 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.
- 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.
- 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).
- 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.

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.
LOL – my kids won’t eat them either, but my labs will!
Can I use frozen Brussel sprouts ?
Hi Staci, they won’t get crispy like fresh, but the topping will give the dish a crispy texture.
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!
Fabulous. I should have made 2, everyone loved it, they were scraping the dish to get every last bit!
Hi Jen
Im interested in that what baking dish you used for the brussels sprouts recipe. Would you please tell me the brand? Thanks
Donna
Hi Donna, That’s a really old dish and I don’t remember where I got it — sorry!
OMG. This recipe is sooo good and straightforward. If you are wavering, try it. You will not be disappointed. I cooked this in my toaster oven and it was a breeze.
Hi do you toast the bread prior to mixing with cheese, etc?
Hi Anastasia, no, it’s not necessary to toast the bread crumbs. Hope you enjoy!
