How to Make Cheesy Chicken Fajita Casserole

Step 1: Prepare the Chicken and Veggies

Start by slicing the chicken into thin strips and seasoning with fajita spices. Sauté the chicken in olive oil over medium-high heat until cooked through. In the same pan, toss in sliced bell peppers and onions, cooking just until tender but still crisp. This builds the foundational flavor for your casserole.

Step 2: Assemble the Layers

In a greased casserole dish, lay down a single layer of tortillas to create a base. Next, spread half the cooked chicken and vegetables evenly on top. Dollop spoonfuls of sour cream and sprinkle a generous amount of cheese. Repeat layers with remaining tortillas, chicken mixture, sour cream, and finish with a final cheese topping.

Step 3: Bake Until Bubbly

Preheat your oven to 375°F (190°C). Cover the casserole with foil and bake for 25 minutes, then remove the foil and bake an additional 10-15 minutes until the cheese is golden and bubbly. Let it cool for a few minutes before serving to let the flavors settle.

Pro Tips for Making Cheesy Chicken Fajita Casserole

• Use Fresh Veggies: The freshness of the bell peppers and onions makes a noticeable difference in flavor and texture.
• Don’t Overcrowd the Pan: Sauté chicken and veggies in batches if needed to avoid steaming and ensure even browning.
• Layer Wisely: Distribute ingredients evenly for consistent flavor in every bite.
• Let it Rest: Allow the casserole to cool slightly before cutting to help it set and prevent sogginess.
• Double the Cheese: If you’re a cheese lover, don’t be shy about adding extra for that irresistible gooey finish.
