Cheesy Cauliflower Breakfast Casserole

I love finding new ways to add veggies to my meals. This cauliflower breakfast casserole swaps in riced cauliflower for the usual hash browns to make it not only keto-friendly but also a real crowd-pleasing addition to the brunch rotation. —Robyn Warren, Lakeway, Arkansas
  • Total Time
    Prep: 30 min. Bake: 40 min. + standing
  • Makes
    12 servings


  • 1 pound bacon strips, chopped
  • 1 cup chopped sweet onion
  • 1/2 large sweet red pepper, chopped
  • 1/2 large green pepper, chopped
  • 9 large eggs, lightly beaten
  • 1-1/2 cups whole-milk ricotta cheese
  • 4 cups frozen riced cauliflower, thawed
  • 2 cups shredded cheddar cheese
  • 1 cup shredded Swiss cheese
  • 1/2 teaspoon pepper
  • 1/4 teaspoon salt


  • Preheat oven to 350°. In a large skillet, cook bacon over medium heat until crisp, stirring occasionally. Remove with a slotted spoon; drain on paper towels. Discard drippings, reserving 1 tablespoon in pan.
  • Add onion and chopped peppers to drippings; cook and stir over medium-high heat until tender, 6-8 minutes. In a large bowl, whisk eggs and ricotta. Stir in riced cauliflower, shredded cheeses, bacon, onion mixture, pepper and salt. Pour into a greased 13x9-in. baking dish. Bake, uncovered, until a knife inserted near the center comes out clean, 40-45 minutes. Let stand 10 minutes before serving.
  • Freeze option: Cool baked casserole completely; cover and freeze. To use, partially thaw in refrigerator overnight. Remove from refrigerator 30 minutes before baking. Preheat oven to 350°. Bake casserole as directed, increasing time as necessary to heat through and for a thermometer inserted in center to read 165°.

    This was delish! My stepmom made it with sausage instead. She added a little hot sauce and season salt. My 17 yo son loved it as well. Will keep this in the rotation. Great idea to make for the week for my son to warm up before school.

    My husband had a lot of doubts about the cauliflower but ended up liking the texture along with the cheese and bacon! This is a great option if you need to cut down on carbs but still want to eat something delicious.

    This taste great. I cut into individual servings, wrapped in plastic wrap and placed into a gallon sized storage bag. Great for breakfast, lunch or dinner.
