Ingredients

For the Chicken

2 large boneless, skinless chicken breasts, sliced into thin strips
2 tablespoons olive oil
Juice of 1 lime
3 bell peppers (red, yellow, and green), sliced
1 large onion, sliced

Fajita Seasoning

2 teaspoons paprika
1 teaspoon ground cumin
1 teaspoon garlic powder
1 teaspoon onion powder
1 teaspoon chili powder
½ teaspoon dried oregano
½ teaspoon black pepper
1 teaspoon salt
¼ teaspoon cayenne pepper (optional)

Optional Toppings

Warm flour tortillas
Shredded cheddar cheese
Sour cream
Fresh cilantro
Sliced avocado
Salsa
Guacamole
Lime wedges

Instructions

Step 1: Prepare the Chicken

Slice the chicken breasts into thin, even strips. Keeping the pieces the same size helps them cook evenly and stay tender.

Step 2: Slice the Vegetables

Wash the bell peppers thoroughly. Remove the seeds and slice them into thin strips. Slice the onion into similar-sized strips so everything cooks at the same rate.

Step 3: Make the Seasoning

In a small bowl, combine the paprika, cumin, garlic powder, onion powder, chili powder, oregano, salt, black pepper, and cayenne pepper if using. Stir well until all the spices are evenly mixed.

Step 4: Combine Everything

Place the chicken, peppers, and onions into a large mixing bowl. Add the olive oil, lime juice, and fajita seasoning. Toss everything together until the chicken and vegetables are evenly coated with the seasoning mixture.

For even more flavor, let the mixture marinate for 20 to 30 minutes before cooking.

Step 5: Prepare the Foil Packets

Preheat your oven to 400°F (200°C).

Cut four large sheets of heavy-duty aluminum foil.

Divide the chicken and vegetable mixture evenly among the foil sheets. Fold the foil over the filling and seal the edges tightly to create secure packets that will trap steam during cooking.

Step 6: Bake

Place the foil packets on a large baking sheet.

Bake for 20–25 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the vegetables are tender.

If you’d like slightly roasted vegetables, carefully open each packet during the last 5 minutes of baking.

Step 7: Grill Option

Preheat your grill to medium-high heat.

Place the sealed foil packets directly on the grill.

Cook for about 18–22 minutes, flipping the packets halfway through cooking.

Serving Suggestions

Chicken Fajita Foil Packets are incredibly versatile and can be served in many different ways.

Serve the chicken and vegetables inside warm flour tortillas for classic chicken fajitas, or enjoy them over steamed white rice, brown rice, or cilantro lime rice. They also pair perfectly with Mexican rice, black beans, corn salad, or a fresh green salad.

Top your fajitas with shredded cheese, sour cream, sliced avocado, homemade guacamole, fresh cilantro, salsa, or a squeeze of fresh lime juice for even more flavor.

Storage Instructions

Store leftovers in an airtight container in the refrigerator for up to 3 days.

To freeze, allow the chicken mixture to cool completely before placing it in freezer-safe containers or bags. Freeze for up to 2 months.

Reheat in the microwave, oven, or skillet until thoroughly heated before serving.

Tips for the Best Chicken Fajita Foil Packets

Heavy-duty aluminum foil works best because it prevents leaks and tears.

Can I cook these over a campfire?
Yes. Place the sealed foil packets over medium campfire coals and cook for approximately 20–25 minutes, turning them once halfway through.

What vegetables can I add?
Mushrooms, zucchini, yellow squash, cherry tomatoes, corn, and sliced jalapeños all make delicious additions.
