Ingredients

4 boneless, skinless chicken breasts
2 tbsp olive oil
Salt and pepper to taste
1 tbsp garlic powder
1 tbsp onion powder
1 cup heavy cream
1/2 cup chicken broth (low sodium)
1 1/2 cups grated mozzarella cheese
1/2 cup grated Parmesan cheese
1/4 cup cream cheese, softened
1/2 tsp Italian seasoning
1 tbsp fresh parsley, chopped (optional)
1 cup cauliflower florets (optional for a “noodle” substitute)

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

Preheat the oven to 375°F (190°C).
Season the chicken breasts with salt, pepper, garlic powder, and onion powder.
Heat olive oil in a large skillet over medium heat. Add the chicken breasts and cook for 6-7 minutes per side, until golden brown and cooked through. Remove the chicken from the skillet and let it rest for a few minutes before slicing it into bite-sized pieces.
If using cauliflower, steam or microwave the cauliflower florets until tender, then chop into smaller pieces to resemble “noodles.”
In the same skillet, add the chicken broth and bring to a simmer. Scrape any browned bits from the pan to incorporate into the sauce.
Stir in the heavy cream, cream cheese, mozzarella, Parmesan, and Italian seasoning. Simmer for 3-5 minutes until the sauce is thickened and the cheeses are melted.
In a large casserole dish, combine the cooked chicken, cauliflower (if using), and the creamy Alfredo sauce. Mix well to coat everything evenly.
Sprinkle the remaining mozzarella cheese on top and bake for 20-25 minutes, until the casserole is bubbling and golden brown.
Garnish with fresh parsley, if desired, and serve hot.

Variations

Make it dairy-free: Substitute the heavy cream with coconut cream and use dairy-free cheese alternatives to make this casserole dairy-free.
Use shirataki noodles: For a more pasta-like texture, use shirataki noodles instead of cauliflower as a low-carb alternative.

FAQs

1. Can I use frozen chicken breasts?

Yes, you can use frozen chicken breasts, but it’s best to thaw them before cooking. If cooking from frozen, increase the cooking time by 10-15 minutes.

2. Can I use a different type of cheese?

Yes, you can substitute mozzarella with provolone or even cheddar cheese. Keep in mind that it may alter the flavor slightly, but it will still be delicious.

3. Can I make this casserole ahead of time?

Yes, you can assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours before baking. Just bake it as directed when you’re ready to eat.

4. Can I add more vegetables to the casserole?

Absolutely! Feel free to add sautéed spinach, broccoli, or even bell peppers to enhance the flavor and nutritional value.

5. How do I make the sauce thicker?

If the sauce is too thin, you can simmer it for a few more minutes to reduce it. Alternatively, you can mix a small amount of xanthan gum or cornstarch with water to thicken the sauce.

6. Can I freeze this casserole?

Yes, you can freeze the casserole for up to 3 months. Allow it to cool completely, then wrap tightly in plastic wrap and foil. Thaw in the refrigerator overnight and bake as directed.

7. Can I use regular pasta instead of cauliflower?

If you’re not following a keto diet, you can absolutely swap out the cauliflower for regular pasta. Just be sure to adjust the cooking time for the pasta.

8. Can I use a slow cooker for this recipe?

Yes, you can cook the chicken in a slow cooker and then combine it with the sauce and cheese to finish in the oven, or cook everything in the slow cooker for a hands-off approach. Just cook on low for 3-4 hours.

9. How can I make the casserole spicier?

Add red pepper flakes or diced jalapeños to the sauce to give it a little heat. Adjust the amount based on your spice preference.
