Creamy Low-Carb Chicken and Broccoli Alfredo Casserole: Step-by-Step Instructions

Step-by-Step Instructions

Step 1: Preparation

Preheat your oven to 350°F (175°C). Lightly grease a 9x13-inch baking dish with butter or non-stick spray. Pat the chicken breasts dry with paper towels to ensure a good sear. Season both sides evenly with 1 teaspoon of salt, pepper, oregano, paprika, and garlic powder.

Step 2: Sear the Chicken

Heat the olive oil or butter in a large skillet over medium-high heat. Add the seasoned chicken and sear for 4 to 5 minutes per side until deeply browned. Remove the chicken from the pan, let it rest on a cutting board for a few minutes, then cut into bite-sized cubes.

Step 3: Sauté Aromatics

Lower the skillet heat to medium. Add the finely chopped onion and sauté for 3 to 4 minutes until soft and translucent. Stir in the minced garlic and cook for just 30 seconds until it becomes fragrant, careful not to burn it.

Step 4: Make the Sauce

Pour the heavy cream into the skillet, using a wooden spoon to scrape up all browned bits from the bottom. Bring to a gentle simmer, then remove from heat. Stir in the Parmesan cheese until smooth, then fold in the fresh spinach until it is wilted.

Step 5: Assemble the Casserole

Arrange the raw broccoli florets in a single layer in the prepared baking dish. Distribute the diced chicken evenly over the broccoli. Pour the creamy spinach Alfredo sauce over the top, then sprinkle generously with the shredded mozzarella cheese.

Step 6: Bake and Garnish

Bake the casserole uncovered for 25 minutes, or until the broccoli is tender and the cheese is bubbly and lightly browned. Remove from the oven, garnish with fresh parsley, and let the dish rest for 5 minutes before serving.

Tips for Success

• For extra tender broccoli, you can steam or blanch the florets for 2 minutes before assembling the casserole to ensure they cook through.
• Grating your own Parmesan and mozzarella cheese from blocks ensures the smoothest sauce and best melt without anti-caking agents.
• Make sure the chicken is very dry before searing to achieve a deep golden crust rather than steaming the meat.
• If you prefer a bit of heat, you can add a pinch of red pepper flakes to the cream sauce while it is simmering.

Variations

• Add sliced mushroomsed with the onions for an extra earthy depth that complements the creamy spinach sauce perfectly.
• Substitute the chicken with roasted turkey or grilled shrimp for a different protein profile while keeping the same base.
• Incorporate some sun-dried tomatoes into the sauce for a burst of tangy acidity that cuts through the rich cream.

Storage and Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, use the oven at 350°F covered for about 15 minutes, or the microwave for 2 minutes. This casserole does not freeze well, as the cream-based sauce may separate and lose its velvety texture upon thawing.
