Ingredients You’ll Need
Gathering the right ingredients is the first step to creating this delicious dish. Each component brings something special to the table, from the tender chicken breasts to the colorful bell peppers that add crunch and sweetness, all topped off with melty cheese that brings everything together.
- 4 boneless, skinless chicken breasts: The perfect lean protein base that cooks beautifully in the oven.
- 1 tablespoon olive oil: Helps to keep the chicken moist and allows the fajita seasoning to stick.
- 1 packet (or 2 tablespoons) fajita seasoning: A fragrant blend of spices that delivers the warm, smoky fajita flavor.
- 1 red bell pepper, sliced: Adds a sweet crunch and vibrant red color to the dish.
- 1 green bell pepper, sliced: Balances the sweetness with a fresher, slightly earthy bite.
- 1 yellow onion, sliced: Softens and caramelizes slightly during baking, adding depth and sweetness.
- 1 cup shredded Mexican blend or cheddar cheese: Melts into a luscious, cheesy topping that makes this dish irresistible.
- Fresh cilantro and lime wedges (optional): Brighten and freshen each bite with herbal and citrus notes.
How to Make Cheesy Baked Fajita Chicken Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 400°F (200°C). While the oven warms, lightly grease a baking dish to prevent sticking and set the stage for a clean, easy bake.
Step 2: Season the Chicken
Rub the chicken breasts all over with olive oil to lock in moisture during baking. Then, sprinkle the fajita seasoning evenly on both sides of the chicken to ensure every bite bursts with bold flavor.
Step 3: Arrange the Chicken and Veggies
Place the seasoned chicken breasts in your baking dish. Scatter the sliced red and green bell peppers along with the yellow onions around and over the chicken. This layering lets the veggies roast while infusing the chicken with their natural sweetness and aroma.
Step 4: Bake Covered
Cover the dish with foil to trap steam, helping the chicken cook gently and stay juicy. Bake for 20 to 25 minutes or until the chicken is nearly done. This step ensures the meat is tender before adding the cheese.
Step 5: Add Cheese and Finish Baking
Remove the foil and sprinkle a generous cup of shredded cheese over the chicken and veggies. Return the dish to the oven uncovered for another 8 to 10 minutes. During this time, the cheese melts into a bubbly, golden layer while the chicken finishes cooking to a safe 165°F internal temperature.
Step 6: Rest and Garnish
Let the Cheesy Baked Fajita Chicken rest for about 5 minutes after removing it from the oven. This pause helps the juices settle. Garnish with fresh cilantro and serve with lime wedges for a delicious pop of brightness.

Creative Ways to Present

Make Ahead and Storage
Storing Leftovers
Leftover Cheesy Baked Fajita Chicken keeps well in an airtight container in the refrigerator for up to 3 days. Make sure to store the chicken and veggies together to preserve the melding of flavors and prevent the chicken from drying out.
Freezing
You can freeze leftover portions by placing them in freezer-safe containers or heavy-duty freezer bags. For best quality, consume within 2 months. Thaw overnight in the fridge before reheating to maintain texture and taste.
Reheating
To reheat, cover the chicken with foil to keep moisture in and bake in a 350°F (175°C) oven for 15-20 minutes until warmed through. Alternatively, microwave on medium power in short bursts to avoid overcooking the chicken and melting too much cheese.
FAQs
