How to Make Chicken Fajita Nacho Bake:
Ready to create this delicious Chicken Fajita Nacho Bake? Follow these easy steps for a fiesta in every bite!
Step 1:
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish and set aside.
Step 2:
In a large skillet, heat olive oil over medium-high heat. Add the sliced chicken strips, season with chili powder, cumin, smoked paprika, oregano, salt, and pepper. Cook for 5-7 minutes until chicken is cooked through and lightly browned. Remove chicken from skillet and set aside.
Step 3:
In the same skillet, add the sliced bell peppers and onions. Sauté for about 5 minutes until softened but still slightly crisp. Add minced garlic and cook for another 30 seconds until fragrant.
Step 4:
Return the chicken to the skillet and stir to combine with the veggies. If using black beans and corn, stir them in now. Taste and adjust seasoning as needed.
Step 5:
Spread half of the tortilla chips evenly in the prepared baking dish. Layer half of the chicken fajita mixture over the chips.
Step 6:
Sprinkle half of the shredded cheese over the chicken and veggies.
Step 7:
Repeat with the remaining tortilla chips, then the rest of the chicken mixture, and top with the remaining cheese.
Step 8:
Place the baking dish in the preheated oven and bake for 15-20 minutes, or until the cheese is fully melted and bubbly, and the edges of the chips are golden.
Step 9:
Remove from oven and let cool slightly before garnishing with your favorite toppings like fresh cilantro, sliced jalapeños, sour cream, guacamole, and lime wedges.
Tips for Success:
- Use sturdy tortilla chips that can hold up to the toppings without getting soggy quickly. Thick restaurant-style or kettle-cooked chips work best.
- Don’t skip the sear on the chicken to lock in flavor and texture.
- If you prefer a spicier dish, add chopped jalapeños to the chicken or sprinkle cayenne pepper into the seasoning mix.
- For a creamier bake, drizzle some queso or sour cream over the layers before baking.
- Keep an eye on the bake towards the end to avoid burning the cheese or chips.
- Let the bake rest a few minutes after coming out of the oven; this helps the cheese set slightly and makes serving easier.
- Add a squeeze of fresh lime juice right before serving to brighten flavors.

Equipment Needed:
- Large skillet or frying pan
- 9×13-inch baking dish

- Different Cheeses: Use queso fresco, Cotija, or a blend of mozzarella and cheddar for different textures.
