🍳 Instructions

1. Preheat Oven

Preheat your oven to 425°F (220°C). Line a large rimmed baking sheet with parchment paper or foil for easy cleanup.

2. Season Chicken & Veggies

In a large bowl, combine sliced chicken, bell peppers, and onion. Drizzle with olive oil and lime juice. Sprinkle all fajita seasoning ingredients over the top and toss until everything is evenly coated.

3. Spread on Sheet Pan

Spread the mixture in an even layer on the prepared baking sheet, making sure the chicken strips are not overlapping too much.

4. Roast

Bake for 20–25 minutes, flipping once halfway through, until the chicken is cooked through and the vegetables are tender and slightly charred on the edges.

5. Serve

Serve immediately with warm tortillas and your choice of toppings.

🔁 Variation (From Me!)

🌱 Vegetarian Sheet Pan Fajitas

Replace chicken with sliced portobello mushrooms and add zucchini or black beans. Roast the same way for a hearty, plant-based version!
