Ingredients for Easy Sheet Pan Chicken Fajitas
Here’s what you’ll need to bring this flavorful dish together:
For the Chicken & Veggies:
-
1 ½ lbs (680g) boneless, skinless chicken breasts or thighs, sliced into thin strips
-
3 bell peppers (mix of red, yellow, and green), sliced into strips
-
1 large red onion, sliced into strips
-
2 tbsp olive oil
-
Juice of 1 lime (plus extra wedges for serving)
For the Fajita Seasoning:
-
1 ½ tsp chili powder
-
1 tsp cumin
-
1 tsp smoked paprika (or regular)
-
1 tsp garlic powder
-
1 tsp onion powder
-
½ tsp salt (adjust to taste)
-
½ tsp black pepper
-
¼ tsp cayenne pepper (optional, for heat)
For Serving:
-
Flour or corn tortillas, warmed
-
Fresh cilantro, chopped
-
Optional toppings: sour cream, guacamole, salsa, shredded cheese
Step-by-Step Instructions
Step 1: Preheat & Prep
Preheat your oven to 400°F (200°C).
Line a large baking sheet with parchment paper or lightly grease it to prevent sticking.
Step 2: Season the Chicken & Veggies
In a large mixing bowl, combine the sliced chicken, bell peppers, and onions. Drizzle with olive oil and fresh lime juice.
In a separate small bowl, mix together all the fajita seasoning spices. Sprinkle the seasoning evenly over the chicken and veggies, then toss well to ensure everything is coated with flavor.
Step 3: Roast the Fajitas
Spread the seasoned mixture evenly across the prepared sheet pan. Bake for 20–25 minutes, stirring once halfway through, until the chicken is fully cooked (internal temp of 165°F/75°C) and the vegetables are tender.
Optional Tip: Want that sizzling restaurant-style char? Broil the pan for 2–3 minutes at the end of baking.
Step 4: Assemble & Serve
While the fajitas are roasting, warm your tortillas on a skillet, in the oven, or microwave.
Fill each tortilla with a scoop of the roasted chicken and veggies. Top with chopped cilantro and any of your favorite toppings. Finish with a fresh squeeze of lime juice.

Tips for the Best Sheet Pan Fajitas
-
Slice evenly: Cut chicken and veggies into uniform strips to ensure even cooking.
-
Marinate (optional): If you have extra time, let the chicken marinate in the seasoning for 15–30 minutes for deeper flavor.
-
Don’t overcrowd the pan: Spread everything in a single layer to avoid steaming instead of roasting.
-
Make it spicy: Add more cayenne, sliced jalapeños, or a drizzle of hot sauce.

Frequently Asked Questions (FAQ)
Can I make these fajitas ahead of time?
Yes! You can prep the chicken and veggies a day ahead and store them in the fridge. When ready to cook, just spread them on the pan and bake as instructed.
What’s the best chicken to use—breasts or thighs?
Both work well. Chicken thighs tend to be juicier and more flavorful, but chicken breasts cook quickly and stay lean.
Can I use frozen vegetables?
Fresh veggies are best for roasting, but if using frozen, thaw them first and pat dry to avoid excess moisture.
How can I make it spicier?
Add extra cayenne pepper to the seasoning or toss in sliced jalapeños or chili flakes.
Can I double the recipe?
Absolutely. Just use two sheet pans to avoid overcrowding and rotate them halfway through baking.
