Ingredients

Scale

Main Ingredients

  • 1.5 lbs chicken breast, sliced into thin strips
  • 1 red bell pepper, chopped
  • 1 green bell pepper, chopped
  • 1 yellow bell pepper, chopped
  • 1 large onion, chopped
  • 2 tablespoons fajita seasoning (blend of chili powder, cumin, garlic powder, paprika)
  • 1 cup sour cream or Greek yogurt
  • 1 ½ cups shredded cheddar cheese or Mexican cheese blend
  • 2 tablespoons olive oil
  • 2 tablespoons all-purpose flour or 1 cup tortilla strips (optional for thickening or topping)

Instructions

  1. Prep the Chicken and Vegetables: Slice the chicken breasts into thin strips and chop the bell peppers and onions into bite-sized pieces. Toss the chicken with the fajita seasoning and a drizzle of olive oil until evenly coated.
  2. Sauté the Ingredients: Heat olive oil in a large skillet over medium-high heat. Cook the chicken strips until they are just browned and nearly cooked through. Remove the chicken from the pan. In the same pan, sauté the onions and bell peppers until softened and slightly caramelized for natural sweetness.
  3. Combine and Layer: Return the chicken strips to the skillet and mix everything together with sour cream or Greek yogurt to create a creamy sauce. Transfer this mixture evenly into a greased casserole dish.
  4. Add the Cheese Topping: Sprinkle the shredded cheese liberally and evenly over the filling to form a melted, bubbly crust once baked.
  5. Bake Until Bubbly: Preheat the oven to 375°F (190°C). Bake the casserole for 20-25 minutes or until the cheese is melted, golden brown, and bubbling around the edges.

Notes

  • Use freshly ground spices for more vibrant flavor.
  • Do not overcook chicken during sauté; it will finish cooking in the oven to remain juicy.
  • Sauté onions and peppers until caramelized to add natural sweetness that balances spices.
  • Choose a good melting cheese for the best crispy and bubbly topping.
  • Let the casserole rest a few minutes after baking for easier slicing and serving.
