  • 2½ pound Brussels sprouts, trimmed and halved (quartered if large; about 8 cups)
  • 2-3 tablespoons extra-virgin olive oil, divided
  • 1 medium onion, thinly sliced
  • 3 tablespoons all-purpose flour
  • ¾ teaspoon salt
  • ¼ teaspoon white or black pepper
  • 2½ cups low-fat milk
  • 1½ cups fresh whole-wheat breadcrumbs (see Tips) or ½ cup shredded or crumbled cheese


  • Active

  • Ready In

  1. Position racks in upper and lower third of oven; preheat to 425°F.
  2. Toss Brussels sprouts in a large bowl with 1 tablespoon oil until well coated. Divide between 2 baking sheets and spread in an even layer. Roast, stirring once and rotating the pans top to bottom about halfway through, until tender and beginning to brown, 20 to 25 minutes.
  3. Meanwhile, heat 1 tablespoon oil in a large saucepan over medium heat. Add onion and cook, stirring frequently, until very soft and golden brown, 5 to 8 minutes. Add flour, salt and pepper; cook, stirring, for 1 minute more. Add milk and continue to stir, scraping up any browned bits. Cook, stirring, until the sauce bubbles and thickens enough to coat the back of a spoon, about 4 minutes. Remove from the heat. (See Tips)
  4. When the Brussels sprouts are done, remove from the oven. Preheat the broiler.
  5. Transfer half the Brussels sprouts to a 2-quart, broiler-safe baking dish. Spread half the sauce over the Brussels sprouts. Add the remaining Brussels sprouts and top with the remaining sauce.
  6. Combine breadcrumbs and the remaining 1 tablespoon oil in a small bowl (skip this step if you are topping with cheese).
  7. Sprinkle the breadcrumb mixture (or cheese) over the gratin. Place under the broiler and broil, watching closely, until the gratin is bubbling and beginning to brown on top, 1 to 5 minutes, depending on your broiler. Let stand for 10 minutes before serving.
  • Make Ahead Tip: Roast Brussels sprouts (Step 2) up to 30 minutes ahead. Prepare the sauce (Step 3), cover and refrigerate for up to 1 day; gently reheat until steaming before combining with the Brussels sprouts.
  • Tips: To make your own fresh breadcrumbs, trim crusts from whole-wheat bread. Tear bread into pieces and process in a food processor until coarse crumbs form. One slice of bread makes about ½ cup fresh breadcrumbs.
  • To add extra flavor to the cream sauce, at the end of Step 3 stir in 1 tablespoon chopped fresh herbs, such as thyme, sage or parsley. Or make it cheesy by stirring in ½ cup shredded or crumbled cheese, such as Gruyère, Swiss, Cheddar or blue cheese.
  • Keep food fresh: If you're storing food in your fridge for a few hours or more, it's best to keep it in an airtight container or in a container covered tightly with foil. Foil is best at creating a barrier that doesn't let unwanted flavors in (or out) while you store your food.

Creamy yet guilt-free, and very tasty! I had 2 cups sprouts on hand for just the two of us and it was easy to reduce the recipe. 20 minutes was plenty to roast the sprouts. Used a touch of shredded Jarlsberg Swiss instead of bread crumbs. Nice creamy texture and wonderful flavor. This is a keeper!

A little bland but otherwise, a good fall side dish Hmm, not sure what this is missing but it's a little bland. I guess if you are serving this as a side (which I would assume you would) and eating it in combination with something else then it wouldn't matter as much. I think 25 minutes is not enough to roast the brussels sprouts and I would suggest maybe even doubling the time to bring out its natural nutty flavour. Pros: Not too many steps, easy to throw together Cons: Needs more than salt and pepper
