Brussels Sprouts Gratin

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 a perfect holiday side because you can make most of it ahead of time. Like my cauliflower gratin, it’s rich, creamy, and baked until golden and bubbling—but this version is even easier. Instead of fussing with a béchamel sauce, it uses heavy cream to keep things simple. 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 (220°C). Put the Brussels sprouts in a 9 x 13-inch (23 x 33-cm) 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).

I’ve made this recipe several times and each time it comes out perfectly. I never deviate from the recipe and it is delicious.
Made this last night. Followed the recipe exactly as written. It was delicious! DH and my 2 boys really do not like Brussels sprouts… the boys are picky eaters, but everyone loved it! DH and one boy even went back for seconds!
My mother hates Brussels sprouts, but she absolutely loved this!
Excellent recipe for brussels! I was looking for something a little different and the gratin did it. My husband loved it and asked that I make it again…immediately!
Love Brussels sprouts and love that this can be made the day before. Might add some crispy bacon bits to the topping before baking. Finally, sun in the Pacific Northwest. Planted 5 Brussels sprouts plants yesterday. Will make this recipe for sure. Thanks ??!
I love the Brussels Sprouts Au Gratin recipe. We love the sprouts and this is so easy and delicious! Try it, you’ll like it. Mikey likes it!
Brussels sprouts are one of my food loves and I am always looking for new ways to serve them. This recipe, followed to the letter, is incredible. Make it! The crunchiness really stands out and enhances the overall appeal.
Perfect as written; creamy, nutty, and delicious. Easy enough for weeknights, and fancy enough for holidays. Great recipe!
I have another brussels sprouts gratin recipe; but it is much heavier than this one. This is simpler to assemble, lighter, but still with a rich flavor. The taste of the sprouts really comes through!
I enjoy your recipes so much, please keep creating! I made this last night with ingredients I had on hand (store bought italian breadcrumbs, half and half and parmesiano regiano.) This dish was decadent! I’m eating the leftovers for breakfast with my coffee. I can’t wait to try it as written.
