  • 2 heads cauliflower, cut into florets
  • 5 eggs
  • 1 ½ cups heavy cream
  • 1 1/2 teaspoons salt
  • ½ teaspoon pepper
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 4 tablespoons butter, melted
  • 2 cups shredded white cheddar cheese
  • 1/2 cup grated parmesan cheese
  • ½ cup shredded mozzarella cheese
  • Additional ½ cup grated parmesan for topping


1. Prepare the Cauliflower

  1. Preheat the Oven: Preheat your oven to 375°F (190°C).
  2. Boil the Cauliflower: Bring a large pot of water to a boil. Add the cauliflower florets and cook for 5-7 minutes, until tender but not mushy. Drain well and set aside.

2. Prepare the Cheese Mixture

  1. Whisk the Eggs: In a large bowl, whisk together the eggs, heavy cream, salt, pepper, garlic powder, and onion powder until well combined.
  2. Add the Cheeses: Stir in the melted butter, shredded white cheddar cheese, grated parmesan cheese, and shredded mozzarella cheese until fully incorporated.

3. Assemble the Casserole

  1. Combine Cauliflower and Cheese Mixture: Add the drained cauliflower florets to the cheese mixture, stirring gently to coat all the florets evenly.
  2. Transfer to Baking Dish: Pour the cauliflower mixture into a greased 9×13-inch baking dish, spreading it out evenly.
  3. Top with Parmesan: Sprinkle the additional ½ cup of grated parmesan cheese evenly over the top.

4. Bake

  1. Bake the Casserole: Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the casserole is bubbly and the top is golden brown.
  2. Cool Slightly: Allow the casserole to cool for about 10 minutes before serving to let the flavors meld and the dish set slightly.

5. Serve

  1. Serve: Scoop servings onto plates and enjoy while warm. This casserole pairs wonderfully with a crisp green salad or roasted vegetables.

Cook’s Notes and Variations


  • Cauliflower: Ensure the cauliflower is well-drained to avoid a watery casserole. You can also pat the florets dry with a paper towel.
  • Cheese: Feel free to experiment with different cheeses like gouda, fontina, or gruyère for varied flavors.
  • Creaminess: For an even creamier texture, substitute half of the heavy cream with sour cream or cream cheese.


  1. Bacon Cheddar Cauliflower Casserole: Add cooked, crumbled bacon and swap out the white cheddar for sharp cheddar cheese.
  2. Broccoli-Cauliflower Casserole: Mix in steamed broccoli florets with the cauliflower for a colorful and nutritious twist.
  3. Spicy Kick: Add a pinch of red pepper flakes or a diced jalapeño to the cheese mixture for a spicy version.
  4. Herb-Infused: Add fresh or dried herbs like thyme, rosemary, or parsley to the cheese mixture for an aromatic flavor.
