These Chicken Fajita Foil Packets are an easy dinner recipe that's perfect for summer! Slices of chicken, peppers and red onions cook together with an easy homemade fajita seasoning, on the grill or in the oven. Serve them with warm tortillas for a no mess meal!
Place 1 pound thinly sliced boneless skinless chicken breasts, 1 cup sliced yellow, red, or orange bell pepper, 1 cup sliced green bell pepper, ½½ cup thinly sliced red onion, 2 tablespoons vegetable oil, 2 teaspoons chili powder, 1 teaspoon garlic powder, 1 teaspoon ground cumin, ¾ teaspoon salt, ¼ teaspoon ground black pepper, ¼ teaspoon onion powder, and ¼ teaspoon paprika in a large bowl and toss until evenly combined.
Make the foil packets by layering 2 sheets of aluminum foil, spraying the top layer lightly with nonstick cooking spray. Repeat until you have four sets of foil.
Divide the chicken mixture evenly between the 4 sets of foil. Fold over the tops and tightly fold up the sides to contain the fajita mixture inside.
Place the packets on the grill directly over the heat and cook for 12-15 minutes, until the chicken is completely cooked through and reaches an internal temperature of 165 degrees Fahrenheit.
Serve the packets with 6-8 flour fajita tortillas and your desired toppings on the side.
