Easy Cauliflower Gratin

Prep Time:
25 mins
Total Time:
1 hrs 5 mins

With all the richness of a traditional potato gratin, this vegetable rendition is just as satisfying, but it's healthier.


  • 3 slices white sandwich bread, torn into large pieces

  • 2 tablespoons grated Parmesan cheese

  • 3 tablespoons butter

  • cup all-purpose flour

  • 2 cups milk

  • 1 head cauliflower (about 2 pounds), cored and cut into small florets

  • Coarse salt and ground pepper

  • 4 ounces Gruyere cheese, grated (1 cup)


  1. Preheat oven to 350 degrees. In a food processor, combine bread and Parmesan. Pulse until coarse crumbs form, about 3 to 4 times; set aside.

  2. In a large saucepan with a lid, melt butter over medium heat. Add flour; cook, whisking constantly for 1 minute. Whisk in milk.

  3. Add cauliflower, and season with salt and pepper. Bring to a boil, and reduce to a simmer. Cover, and cook until starting to soften, about 5 minutes. Remove from heat; gradually stir in Gruyere.

  4. Pour mixture into a 2-quart baking dish, and sprinkle with breadcrumb mixture. Cover with aluminum foil; bake until cauliflower is easily pierced with a knife, about 20 minutes. Remove foil, and bake until breadcrumbs are golden brown, about 20 minutes more. Serve.
