Low-Carb Chicken and Spinach Casserole Recipe

For this delicious casserole, you’ll need the following ingredients:

Optional Add-ons

• Sliced mushrooms
• Diced onions
• Chopped bell peppers
• Crushed red pepper flakes for a spicy kick

Step-by-Step Instructions for Chicken and Spinach Casserole

Step 1: Preheat the Oven

Preheat your oven to 500°F. Lightly spray a 13 x 9-inch baking dish with cooking spray and set it aside.

Step 2: Prepare the Creamy Sauce

In a mixing bowl, combine mayonnaise, sour cream, grated Parmesan cheese, ground black pepper, Italian seasoning, and garlic salt. Stir until the ingredients are well combined and smooth.

Step 3: Layer the Spinach

Pack the casserole dish with fresh spinach, creating an even layer at the bottom. The spinach will wilt as it cooks, so don’t worry if it seems like a lot.

Step 4: Add the Chicken

Place the uncooked chicken breasts on top of the spinach. Ensure the chicken pieces are evenly spaced for uniform cooking.

Step 5: Spread the Creamy Sauce

Evenly spread the creamy sauce mixture over the chicken breasts, ensuring they are fully covered. This will keep the chicken moist and flavorful.

Step 6: Sprinkle with Cheese

Sprinkle shredded Monterey Jack cheese over the top of the creamy sauce, covering the entire surface. This will create a deliciously cheesy crust as it bakes.

Step 7: Bake the Casserole

Place the casserole dish on the bottom rack of the preheated oven. Bake for 22-27 minutes or until the spinach has wilted and the chicken breasts are thoroughly cooked. The cheese should be melted and bubbly with a golden brown top.

Storage and Serving

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave until warmed through. Serve this casserole on its own or with a side of rice, quinoa, or crusty bread for a complete meal.

Tips for Success

• Use Fresh Spinach: Fresh spinach works best for this recipe, but you can also use frozen spinach (thawed and drained) if needed.
• Check Chicken Doneness: Ensure the chicken reaches an internal temperature of 165°F for safe consumption.
• Customize the Creamy Sauce: Add your favorite herbs and spices to the creamy sauce for a personalized touch.

Variations

• Mushroom and Onion Addition: Sauté sliced mushrooms and onions and layer them with the spinach for added flavor and texture.
• Low-Carb Option: Use a low-carb mayonnaise and sour cream for a keto-friendly version.
• Cheese Swap: Substitute Monterey Jack with mozzarella, cheddar, or a blend of cheeses for a different flavor profile.

In Conclusion

Chicken and spinach casserole is a delightful dish that combines the goodness of spinach with tender chicken and a luscious creamy sauce. It’s an easy, nutritious, and versatile meal that’s sure to become a staple in your recipe collection. Whether you’re cooking for a crowd or meal prepping for the week, this casserole offers a comforting and satisfying dining experience.
