Step‑by‑Step Instructions for Cheesy Chicken Fajita Casserole
Step 1: Preheat Your Oven
Begin by preheating your oven to 400°F (200°C). This ensures it’s hot and ready for baking, allowing the cheese on top of your Cheesy Chicken Fajita Casserole to melt perfectly and become golden. While the oven heats up, gather all your ingredients and equipment, including an oven-proof skillet for the next steps.
Step 2: Sauté the Vegetables
In a large oven-proof skillet, heat 2 tablespoons of avocado oil over medium heat. Once the oil shimmers, add sliced green and red bell peppers along with the diced onion. Sauté these colorful vegetables for about 2–4 minutes, stirring occasionally, until they soften and release a fragrant aroma, creating a vibrant base for your casserole.
Step 3: Add Fajita Seasoning
Sprinkle in the majority of the fajita seasoning packet, reserving about 1 tablespoon for later. Stir everything together and continue to cook for another 4 minutes. This step allows the spices to bloom, enhancing their flavors, while the peppers and onions turn tender and aromatic, filling your kitchen with delightful Tex-Mex scents.
Step 4: Incorporate the Chicken and Tomatoes
Next, in a separate bowl, combine the shredded rotisserie chicken with the reserved tablespoon of fajita seasoning. Add this mixture to the skillet along with the diced tomatoes (and their juices) and stir well. Cook everything together for an additional 2 minutes until heated through, ensuring the shredded chicken is coated in all the delicious flavors.
Step 5: Mix in Lime Juice and Tortillas
Turn off the heat and drizzle in the fresh lime juice, giving a vibrant kick that brightens your Cheesy Chicken Fajita Casserole. Gently fold in the extra-thin corn tortilla strips until they are evenly distributed throughout the mixture, ensuring every bite has that comforting tortilla texture that complements the savory ingredients.
Step 6: Add the Cheese and Bake
Sprinkle the shredded Mexican cheese blend generously over the top of your casserole mixture in the skillet. Slide the skillet into the preheated oven and bake for 15 minutes. Watch as the cheese melts blissfully and turns bubbly and golden, creating an irresistible topping that is the crowning glory of this quick and delightful dish.
