Ingredients

Units Scale

Vegetables

  • 14 ounces cauliflower florets, cut into bite-size pieces

Chicken

  • 32 ounces chicken breast
  • 1 teaspoon onion powder
  • 1 teaspoon garlic powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon pepper
  • 1 tablespoon olive oil

Sauce & Cheese

  • 2 cups keto Alfredo sauce
  • 12 ounces shredded mozzarella cheese, divided (3 ounces for sauce, 9 ounces for topping layers)

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 or until fork-tender, being careful not to overcook it. Drain and pat dry with a paper towel. Set aside.
  2. Prepare the chicken: Cut the chicken breast into 1-inch cubes. Season with onion powder, garlic powder, salt, and pepper evenly.
  3. Cook the chicken: Heat olive oil in a skillet over medium-high heat. Add the cubed chicken and cook for about 10 minutes or until fully cooked and no longer pink inside. Remove from heat and set aside.
  4. Preheat the oven: Set your oven to 350°F (175°C) to prepare for baking the casserole.
  5. Heat Alfredo sauce: In a small pot, warm the keto Alfredo sauce over medium-low heat. Once hot, add 3 ounces of shredded mozzarella cheese to the sauce and stir until the cheese melts completely, creating a smooth sauce.
  6. Assemble the casserole: Spray a 13×9-inch casserole dish with non-stick spray. Spread ½ cup of the keto Alfredo sauce on the bottom of the dish.
  7. Layer one: Add half of the steamed cauliflower as a base layer, then top with half of the cooked chicken, distributing the chicken evenly between the cauliflower pieces.
  8. Add sauce and cheese: Pour ¾ cup of the Alfredo sauce evenly over the cauliflower and chicken layer. Sprinkle 4.5 ounces of shredded mozzarella cheese on top.
  9. Layer two: Repeat the layering with the remaining cauliflower and chicken, followed by the remaining Alfredo sauce, and top with the last 4.5 ounces of mozzarella cheese.
  10. Bake the casserole: Place the assembled casserole in the preheated oven. Bake for 30 minutes or until the casserole is heated through and the cheese on top is fully melted and bubbly.

Notes

  • Be careful not to overcook cauliflower during steaming to avoid mushiness in the casserole.
  • Patting the steamed cauliflower dry helps prevent the casserole from becoming watery.
  • For a richer flavor, use a high-quality keto Alfredo sauce or make your own with cream, butter, garlic, and Parmesan cheese.
  • Leftovers can be stored in an airtight container in the refrigerator for up to 3 days and reheated in the oven or microwave.
  • Feel free to add some fresh herbs like parsley or basil on top before serving for added aroma and freshness.
