How to Make Cheesy Chicken Fajita Casserole

Step 1: Prepare the Chicken and Vegetables

Begin by slicing your chicken into thin strips and seasoning them generously with the fajita seasoning. Then, slice the bell peppers and onions into thin strips. Heat a skillet with olive oil and sauté the chicken until it’s browned and cooked through. Remove the chicken and toss in the veggies, cooking until they’re tender but still slightly crisp.

Step 2: Mix the Creamy Base

In a separate bowl, combine cream cheese or sour cream with some shredded cheese to create a smooth and creamy mixture that will hold all elements together in the casserole.

Step 3: Layer the Casserole

In a greased baking dish, lay down a base of torn or chopped tortillas (or cooked rice for an alternative). Spread half of the cooked chicken and veggie mixture over the base. Spoon half of the cheese-cream mixture on top, then sprinkle with shredded cheese. Repeat the layering to build rich, cheesy layers.

Step 4: Bake to Perfection

Bake the casserole in a preheated oven at 375°F (190°C) for about 20-25 minutes, or until the cheese is bubbly and golden on top.

Step 5: Let It Rest and Serve

Allow the casserole to rest for a few minutes after baking so that it sets up nicely, making slices easier and flavors more melded.

Pro Tips for Making Cheesy Chicken Fajita Casserole

• Fresh is best: Use fresh bell peppers and onions to maximize flavor and texture.
• Don’t overcook the chicken: Slightly undercooked chicken will finish cooking in the oven and stay juicy.
• Layer evenly: Distribute ingredients uniformly to ensure every bite has a balance of flavors.
• Cheese choice matters: Combine cheeses for meltability and sharpness; cheddar + Monterey Jack is a classic duo.
• Rest before serving: Let the casserole cool slightly so it slices cleanly and flavors settle.
