Ingredients

(Makes 4 foil packets; serves 4)

  • 1½ lbs boneless, skinless chicken breasts, sliced into thin, uniform strips
  • 2 large bell peppers (any color), sliced into strips
  • 1 large yellow or red onion, sliced into strips
  • 2 tbsp fajita seasoning (store-bought or homemade)
  • 2 tbsp olive oil
  • 1 lime, cut into wedges (for serving)

Optional additions: Sliced jalapeños for heat, fresh chopped cilantro for garnish, or a splash of soy sauce/tamari for an extra umami boost.

Step-by-Step Instructions

Prep & Toss

In a large mixing bowl, combine the sliced chicken, bell peppers, and onions. Drizzle with the olive oil and sprinkle the fajita seasoning evenly over the top. Toss thoroughly until every piece of meat and vegetable is beautifully coated in the smoky-spicy blend.

Assemble the Packets

Tear off four large sheets of heavy-duty aluminum foil (about 12x18 inches each). Divide the chicken and vegetable mixture evenly, piling it into the center of each foil sheet.

Seal Tightly

Bring the long sides of the foil up to meet in the center, folding them down together two or three times to create a tight seam. Fold and crimp the short ends inward to form a fully enclosed, leak-proof pouch. Leave a little room inside the packet for steam to circulate and cook the food evenly.

Cook to Perfection

Choose your preferred cooking method:

Oven: Bake at 400°F (200°C) for 18–20 minutes.

Grill: Cook over medium heat (about 375°F) for 15–18 minutes, flipping the packets once halfway through.

Campfire: Place directly on hot, glowing coals (not roaring flames) for 20–25 minutes, turning occasionally with tongs.

Serve Hot

Carefully open the packets (watch out for the hot steam!). Squeeze fresh lime juice over the top of each portion. Garnish with fresh cilantro and serve immediately.

Is This Recipe Healthy?
