Ingredients

Scale

Vegetables

  • 14 ounces cauliflower florets (cut into bite-size pieces)

Protein

  • 32 ounces chicken breast

Seasonings

  • 1 teaspoon onion powder
  • 1 teaspoon garlic powder
  • ½ teaspoon salt
  • ¼ teaspoon pepper

Oils and Sauces

  • 1 tablespoon olive oil
  • 2 cups keto Alfredo sauce

Cheese

  • 12 ounces shredded mozzarella cheese (divided)

Instructions

  1. Steam the cauliflower: Place the cut cauliflower in a microwave-safe bowl with 1 cup of water, cover with a damp paper towel, and microwave on high for 3-5 minutes until fork tender without overcooking.
  2. Drain and dry cauliflower: Drain the steamed cauliflower and pat dry with a paper towel. Set aside.
  3. Season the chicken: Cut the chicken breast into 1-inch cubes, then sprinkle with onion powder, garlic powder, salt, and pepper evenly.
  4. Cook the chicken: Heat olive oil in a skillet over medium-high heat. Add the cubed chicken and cook for approximately 10 minutes or until cooked through. Remove from heat and set aside.
  5. Preheat the oven: Preheat the oven to 350°F (175°C).
  6. Heat Alfredo sauce: In a small pot over medium-low heat, warm the keto Alfredo sauce. Once hot, add 3 ounces of shredded mozzarella cheese and stir until melted and smooth.
  7. Prepare the casserole dish: Spray a 13×9 inch casserole dish with non-stick spray. Spread ½ cup of keto Alfredo sauce evenly on the bottom.
  8. Layer cauliflower and chicken: Add half of the steamed cauliflower in a layer, then top with half of the cooked chicken, making sure it fills the spaces between the cauliflower.
  9. Add sauce and cheese: Pour ¾ cup of the warmed keto Alfredo sauce over the cauliflower and chicken, then sprinkle 4.5 ounces of shredded mozzarella on top.
  10. Repeat layers: Repeat with the remaining cauliflower and chicken to form another layer. Pour the remaining keto Alfredo sauce over, and top with the last of the mozzarella cheese.
  11. Bake the casserole: Place the casserole in the preheated oven and bake for 30 minutes or until warmed through and cheese is fully melted and bubbly.

Notes

  • Do not overcook the cauliflower in the microwave to avoid mushy texture.
  • Use fresh mozzarella for a creamier melt or part-skim for lower fat.
  • Keto Alfredo sauce can be homemade or store-bought as long as it’s low-carb friendly.
  • Ensure chicken is fully cooked before assembling the casserole.
  • Let the casserole rest for 5 minutes after baking for easier serving.
