Ingredients You’ll Need

Chicken:

  • 4 boneless, skinless chicken breasts

  • 2 tablespoons olive oil

  • 1 tablespoon fajita seasoning

  • ½ teaspoon garlic powder

  • ¼ teaspoon smoked paprika

  • Salt and black pepper to taste

Vegetables:

  • 1 red bell pepper, thinly sliced

  • 1 yellow bell pepper, thinly sliced

  • 1 green bell pepper, thinly sliced

  • 1 small red onion, thinly sliced

Toppings & Garnish:

  • 1 cup shredded Mexican blend cheese

  • Fresh cilantro, chopped (for garnish)

  • Lime wedges (for serving)

Kitchen Equipment Needed

  • 1 large baking dish (9×13 inches works well)

  • Cutting board and knife

  • Mixing bowl (optional, for seasoning chicken)

  • Foil for covering

  • Oven

Step-by-Step Instructions

1. Preheat the Oven

Set your oven to 400°F (200°C). Lightly grease a baking dish with olive oil or non-stick spray.

2. Season the Chicken

Rub the chicken breasts with olive oil, then sprinkle evenly with fajita seasoning, garlic powder, smoked paprika, salt, and black pepper. Massage seasonings into the chicken to coat well.

Tip: If you have time, let the chicken marinate in the spices for 30 minutes to deepen the flavor.

3. Assemble the Dish

Lay the seasoned chicken breasts in the prepared baking dish. Scatter the sliced red, yellow, and green bell peppers, and red onion evenly over the chicken.

4. Bake Covered

Cover the baking dish with foil and bake for 25 minutes.

5. Add Cheese and Finish Baking

Remove foil and sprinkle the shredded Mexican blend cheese over the top. Return the dish to the oven, uncovered, and bake for another 10–12 minutes until the cheese is melted, golden, and bubbly, and the chicken is cooked through (internal temp should read 165°F or 74°C).

6. Garnish and Serve

Sprinkle with freshly chopped cilantro and serve with lime wedges for a zesty finish.

Recipe Tips and Notes

  • Use Chicken Thighs: Prefer dark meat? Swap in boneless, skinless chicken thighs for a juicier result.

  • Spice Level: Want more heat? Add sliced jalapeños or a pinch of cayenne pepper.

  • Cheese Variations: Try pepper jack or shredded cheddar if you don’t have Mexican blend on hand.

  • Additions: For extra depth, mix in black beans or corn before baking.

  • Low-Sodium Version: Make your own fajita seasoning with less salt to control sodium levels.

Storage and Reheating

Refrigerator: Store leftovers in an airtight container for up to 4 days.

Freezer: Wrap portions tightly and freeze for up to 2 months. Thaw overnight in the fridge before reheating.

To Reheat: Microwave on medium for 2–3 minutes or warm in the oven at 350°F until heated through.

Pro Tip: Slice leftover chicken and use it in wraps, tacos, or on top of salads for a quick lunch.

FAQs

Can I make this ahead of time?

Absolutely! You can assemble the dish a few hours in advance, cover it, and refrigerate until ready to bake.

Is this recipe gluten-free?

Yes! Just make sure your fajita seasoning and cheese are gluten-free certified.

Can I grill the chicken instead?

Yes, you can grill the seasoned chicken breasts and sauté the vegetables separately, then combine and top with cheese before broiling for 2–3 minutes to melt the cheese.

Can I use frozen vegetables?

Fresh is best for texture, but thawed and drained frozen bell peppers and onions will work in a pinch.

What other cheeses can I use?

Cheddar, Monterey Jack, or even a spicy chipotle cheddar are great swaps. Freshly grated cheese melts better than pre-shredded.
