Ingredients
Instructions
- Preheat and prep. Preheat the oven to 400°F (200°C). Lightly grease a 9×13-inch or similar baking dish.
- Season the ingredients. In a large bowl, toss the chicken strips, sliced peppers, and onion with olive oil, fajita seasoning, salt, and pepper until evenly coated.
- Assemble. Spread the chicken and vegetable mixture in an even layer in the baking dish. Sprinkle the shredded cheese evenly over the top.
- Bake. Bake 18–22 minutes until the chicken is cooked through and the cheese is melted and golden. Let rest a few minutes, garnish if desired, and serve.
Notes & Tips
- Cut the chicken into similar-sized strips so it cooks evenly.
- For extra browning, broil for the last 1–2 minutes (watch carefully).
- Use a mix of mozzarella and cheddar for the best melt and flavor.
- This dish reheats well and is excellent for meal prep.
- Serve with a side of guacamole, salsa, or cauliflower rice if desired.
Variations & serving ideas
- Higher protein: Use chicken breast and add a sprinkle of Parmesan on top.
- Spicy: Add sliced jalapeño or a pinch of cayenne to the seasoning.
- Dairy-free: Use dairy-free cheese alternatives.
- Extra veggies: Add zucchini or mushrooms with the peppers.
- Spicy fajita bake: Add sliced jalapeños and a pinch of cayenne or chipotle powder to the seasoning.
- Creamy version: Stir a few tablespoons of cream cheese into the chicken mixture before topping with shredded cheese.
- Shrimp fajita bake: Swap the chicken for large shrimp and reduce the bake time to 12–15 minutes.
- Sheet-pan style: Spread everything on a large sheet pan for even more browning and easier serving.
