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.

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.

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!
Hi Jessica, yep, that would work. Hope you enjoy!
Just tear by hand. Takes 2 minutes. Doesn’t have to be perfect as it all blends in.
