Let’s Make it Together
Preheat Your Oven: Start by preheating your oven to 350°F (175°C). This ensures even cooking once everything goes in.
Sauté the Chicken and Veggies: In a large skillet over medium heat, add vegetable oil. When hot, toss in diced chicken breasts. Cook until browned and no longer pink—your kitchen should smell heavenly right about now.
Add Flavorful Ingredients: Mix in sliced bell peppers and onions into the skillet. Continue cooking until they soften slightly—about 5-7 minutes—while stirring occasionally.
Add Seasoning and Tomatoes: Sprinkle fajita seasoning over the chicken mixture. Stir in canned diced tomatoes (with their juices) until everything is coated nicely—this will infuse every bite with flavor.
Layer It Up!: In a greased baking dish, layer half of the crushed tortilla chips. Spoon half of the chicken mixture on top followed by half of the shredded cheese. Repeat these layers for maximum deliciousness.
Bake to Perfection!: Place the casserole in your preheated oven. Bake for about 20-25 minutes until bubbly and golden brown on top—resist peeking too soon; you’ll want that cheesy goodness to melt just right.
Once it’s out of the oven, let it cool slightly before serving. Top each portion with sour cream or Greek yogurt if desired—the perfect finishing touch!
