Ingredients

14 ounces cauliflower florets (cut into bite-size pieces)
32 ounces chicken breast

1 teaspoon onion powder
1 teaspoon garlic powder

½ teaspoon salt
¼ teaspoon pepper

1 tablespoon olive oil
2 cups keto Alfredo sauce
12 ounces shredded mozzarella cheese (divided)

Instructions

Step 1: Steam the cauliflower by placing the cut florets 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. Avoid overcooking.
Step 2: Drain the cauliflower and pat dry with a paper towel. Set aside.
Step 3: Cut the chicken breast into 1-inch cubes and season with onion powder, garlic powder, salt, and pepper.

Step 4: Heat olive oil in a skillet over medium-high heat. Add the cubed chicken and cook for about 10 minutes until fully cooked. Remove from heat and set aside.
Step 5: Preheat your oven to 350 degrees F (175 degrees C).
Step 6: Warm the keto Alfredo sauce in a small pot over medium-low heat. Stir in 3 ounces of mozzarella cheese until melted and smooth.

Step 7: Prepare a 13×9 inch casserole dish by spraying it with non-stick spray. Spread ½ cup of the Alfredo sauce on the bottom.
Step 8: Layer half of the cauliflower over the sauce.
Step 9: Add half of the cooked chicken over the cauliflower, filling in gaps to cover evenly.

Step 10: Pour ¾ cup of Alfredo sauce over the chicken and cauliflower layer.
Step 11: Sprinkle 4.5 ounces of shredded mozzarella cheese on top.
Step 12: Repeat the layering process with the remaining cauliflower and chicken, followed by the remaining Alfredo sauce and the last of the mozzarella cheese.

Step 13: Bake in the preheated oven for 30 minutes, or until the casserole is heated through and the cheese is melted and bubbly.

Tips & Variations

For extra flavor, add chopped fresh parsley or basil before serving.
Swap chicken breast for cooked sausage or turkey for a different protein twist.

Use homemade keto Alfredo sauce or your favorite store-bought low-carb version.
To make it dairy-free, substitute cheese with a dairy-free alternative that melts well.

Storage

Store leftover casserole in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave or warm the entire dish in a 350-degree oven until heated through, about 15 minutes.
