Ingredients You’ll Need
To make this delicious Keto Chicken Alfredo Casserole, gather the following ingredients:
- 14 ounces of cauliflower florets: Cut into bite-sized pieces for easy layering.
- 32 ounces of chicken breast: Cubed into 1-inch pieces for even cooking.
- Seasonings: 1 teaspoon each of onion powder and garlic powder, ½ teaspoon salt, and ¼ teaspoon pepper.
- 1 tablespoon olive oil: For cooking the chicken.
- 2 cups Keto Alfredo Sauce: Store-bought or homemade.
- 12 ounces shredded mozzarella cheese: Divided for layering.
Step-by-Step Instructions
1. Steam the Cauliflower
Start by steaming the cauliflower. Place the florets in a microwave-safe bowl with 1 cup of water. Cover the bowl with a damp paper towel and microwave on high for 3-5 minutes, or until fork-tender. Be careful not to overcook! Drain the cauliflower and pat it dry with a paper towel. Set aside.
2. Cook the Chicken
Cut the chicken breast into 1-inch cubes and season with onion powder, garlic powder, salt, and pepper. Heat olive oil in a skillet over medium-high heat and cook the chicken for about 10 minutes, or until fully cooked through. Once done, set it aside.
3. Prepare the Keto Alfredo Sauce
If you’re using store-bought keto Alfredo sauce, heat it in a small pot over medium-low heat. Once warm, stir in 3 ounces of mozzarella cheese until melted and the sauce is smooth.
4. Assemble the Casserole
Preheat your oven to 350°F (175°C) and prepare a 13×9-inch casserole dish by spraying it with non-stick spray. Spread ½ cup of keto Alfredo sauce on the bottom of the dish.
- Layer half of the steamed cauliflower evenly across the bottom.
- Add half of the cooked chicken on top, letting it fill in the gaps between the cauliflower.
- Pour ¾ cup of keto Alfredo sauce over the chicken and cauliflower.
- Sprinkle 4.5 ounces of mozzarella cheese on top.
Repeat these steps with the remaining cauliflower, chicken, Alfredo sauce, and mozzarella cheese to create a second layer.
5. Bake
Place the casserole in the preheated oven and bake for 30 minutes, or until heated through and the cheese is fully melted and bubbly.
Serve and Enjoy!
Once baked to perfection, let the casserole cool slightly before serving. Pair it with a simple green salad or some roasted veggies for a complete meal. This dish is so flavorful and satisfying that even picky eaters won’t miss the carbs!
