How to Make Cheesy Chicken Fajita Casserole

Step 1: Preheat Your Oven

Get started by preheating your oven to 400°F (200°C). This will ensure your casserole cooks evenly and quickly.

Layer the sliced bell peppers and onion over the chicken. Sprinkle a touch more fajita seasoning on top, then cover everything with an abundance of shredded cheese.

Step 4: Bake to Perfection

Pop the casserole into the oven and let it bake uncovered for 25-30 minutes. You’ll know it’s done when the cheese is beautifully golden and bubbly.

  • 2 tablespoons fajita seasoning

  • 2 medium bell peppers, cut into strips
  • 1 medium yellow onion, sliced
  • 1 1/2 cups shredded cheese (cheddar, Monterey Jack, or Mexican blend)

Garnish

Instructions

  1. Preheat Oven: Preheat your oven to 400°F (200°C) to ensure it’s ready for baking.
  2. Season Chicken: In a baking dish, season the chicken breasts thoroughly with fajita seasoning and vegetable oil. Use your hands to make sure the seasoning is evenly distributed over the chicken.
  3. Add Vegetables and Cheese: Place the sliced bell peppers and onion over the seasoned chicken. Sprinkle a little more fajita seasoning on top, then generously cover everything with shredded cheese.

Notes

  • To ensure the chicken is cooked thoroughly, insert a meat thermometer into the center of one of the breasts; it should read 165°F (74°C).
