This delicious, cheesy casserole is a great way to enjoy cauliflower, and it makes a wonderful addition to any meal, from everyday dinners to holiday feasts.

The breadcrumb topping adds crunch and buttery flavor, but you can omit it or add toasted almonds for a lower carb casserole. 

Vary it a bit with a cup of steamed shredded carrots along with the cauliflower or use part broccoli in the casserole.

Recipe Variations

  • Add a dash of cayenne pepper to the cheese sauce.
  • For a richer sauce, use part light cream or half-and-half.
  • Use a small head of cauliflower and add 2 to 3 cups of lightly steamed broccoli florets to the broccoli florets to the cauliflower and cheese mixture.
  • Add finely chopped walnuts or pecans to the breadcrumb mixture.
  • Replace the breadcrumb topping with 1/2 cup of toasted slivered almonds. To toast the almonds, spread them out in a dry skillet and cook over medium heat, stirring constantly, until they are lightly browned and aromatic.
  • For a buttered almond topping, put 1/2 cup of slivered almonds in a microwave-safe dish with 1 heaping tablespoon of butter. Microwave the almonds and butter for about 3 minutes on 100% power, stirring frequently.
