How to Make Fajita Chicken Casserole

Step 1: Prep the Chicken and Vegetables

Start by slicing the chicken breasts into thin strips and chopping the bell peppers and onions into bite-sized pieces. Toss the chicken with the fajita seasoning and a drizzle of olive oil to coat evenly.

Step 2: Sauté the Ingredients

Heat olive oil in a large skillet over medium-high heat. Cook the chicken strips until just browned and nearly cooked through. Remove from the pan, then sauté the onions and peppers until they soften and develop slight caramelization for added sweetness.

Step 3: Combine and Layer

Return the chicken to the skillet and mix everything with sour cream or Greek yogurt for a creamy sauce. Transfer this mixture into a greased casserole dish and spread evenly.

Step 4: Add the Cheese Topping

Sprinkle your shredded cheese liberally on top of the casserole, covering the filling evenly to ensure a delightful melted crust.

Step 5: Bake Until Bubbly

Place the dish in a preheated oven at 375°F (190°C) and bake for 20-25 minutes until the cheese is melted, golden, and bubbling around the edges.

Pro Tips for Making Fajita Chicken Casserole

• Use fresh spices: Freshly ground spices bring more depth and brightness to the seasoning mix.
• Don’t overcook chicken: Stop cooking the chicken early in the sauté step since it will finish in the oven, preventing dryness.
• Layer flavors: Sauté onions and peppers until caramelized to develop natural sweetness that balances the spice.
• Cheese selection: Use a good melting cheese for the best crunchy, bubbly top.
• Let it rest: Allow the casserole to cool for a few minutes before serving so it sets nicely and slices cleanly.
