Ingredients

2 boneless, skinless chicken breasts
1 bell pepper, sliced (use any color you prefer—red, yellow, green, or orange)
1 onion, sliced (yellow or red onion works great)
2 tablespoons olive oil
1 tablespoon fajita seasoning (store-bought or homemade blend of chili powder, cumin, paprika, garlic powder, onion powder, oregano, salt, and pepper)
Salt and pepper to taste
Fresh cilantro, chopped (for garnish)
Lime wedges (for serving)

How To Make Fajita Chicken Breast Foil-Packet Dinners

Step 1: Prep the Chicken and Veggies

Start by slicing your bell pepper and onion into thin strips. This helps them cook evenly and quickly inside the foil packets. Next, cut the chicken breasts into thin strips or bite-sized pieces to ensure they cook through without drying out.

Step 2: Season Everything

Place the chicken and sliced vegetables in a large mixing bowl. Drizzle the olive oil over the top, followed by the fajita seasoning, salt, and pepper. Toss everything well until the chicken and veggies are evenly coated with the seasoning and oil. This step is crucial for infusing that signature fajita flavor into every bite.

Step 3: Assemble the Foil Packets

Tear off two large sheets of heavy-duty aluminum foil, one for each chicken breast and accompanying veggies. Divide the chicken and vegetable mixture evenly between the two pieces of foil. Try to keep everything centered to avoid leaks when sealing the packets.

Step 4: Seal the Foil Packets

Fold the foil over the chicken and vegetables, sealing the edges tightly to create a packet. Be sure to fold the edges twice to prevent any steam or juices from escaping during cooking. This locking-in of steam helps keep the chicken moist and tender.

Step 5: Cook

You have a couple of options here:

Oven Method: Preheat your oven to 400°F (200°C). Place the foil packets on a baking sheet and bake for 25-30 minutes, or until the chicken is cooked through and the vegetables are tender.
Grill Method: Preheat your grill to medium-high heat. Place the foil packets directly on the grill grates and cook for about 20-25 minutes, flipping once halfway through.

Step 6: Serve

Carefully open the foil packets (watch out for hot steam!). Transfer the chicken and vegetables to plates or serve right in the packets for a rustic presentation. Garnish with freshly chopped cilantro and a squeeze of lime juice for a bright, fresh finish. Serve with lime wedges on the side.

Expert Tips

Use Fresh Seasonings: Freshly chopped cilantro and freshly squeezed lime juice elevate the flavor, so don’t skip these garnishes.
Don’t Overcrowd the Packets: Give the chicken and vegetables some room to steam properly; overcrowding can lead to uneven cooking.
Try Homemade Fajita Seasoning: Control the salt and spice levels by mixing your own blend. It’s easy and tastes fresher.
Cut Chicken Evenly: Thin, even strips or pieces ensure quick, even cooking and help avoid dry edges.
Pair with Sides: This recipe is perfect alongside rice, quinoa, or even wrapped in warm tortillas for a classic fajita experience.

Variations and Customizations

Vegetables: Swap bell peppers and onions with zucchini, mushrooms, or cherry tomatoes for a different veggie mix.
Spice Level: Add some sliced jalapeños or a pinch of cayenne pepper to the seasoning for a spicy kick.
Cheese: Add shredded cheese (like cheddar or Monterey Jack) to the packet before sealing for a melty, indulgent twist.
Marinades: Marinate the chicken in lime juice, garlic, and a dash of soy sauce before assembling for extra depth of flavor.
Serving Style: Use the cooked chicken and veggies as a topping for salads, bowls, or even nachos.

How to Store Leftovers

If you happen to have any leftover Fajita Chicken Breast Foil-Packet Dinners (though they’re hard to resist!), store them in an airtight container in the refrigerator for up to 3 days. To reheat, simply microwave or warm in a skillet over medium heat until heated through. Avoid reheating in the foil packets directly on the stove.

For longer storage, you can freeze the cooked chicken and vegetable mixture in freezer-safe containers or bags for up to 2 months. Thaw overnight in the fridge before reheating. This makes for quick and easy meals when you’re short on time.

FAQ

Can I use chicken thighs instead of chicken breasts?

Absolutely! Chicken thighs are juicier and can add a richer flavor. Just adjust the cooking time slightly, as thighs may take a bit longer to cook through.

Is it necessary to use foil packets?

While foil packets make cooking and cleanup easy, you can also cook the chicken and veggies in a baking dish or skillet. Just be sure to cover the dish to retain moisture.

How spicy is fajita seasoning?

Fajita seasoning typically has a mild to medium heat level, but you can easily adjust it by adding more chili powder or cayenne pepper if you want a spicier dish.

Can I prepare these foil packets ahead of time?
