What You Need to Make Sheet Pan Chicken Fajitas

Real talk — the ingredient list is short and the prep is even shorter. Here's everything you need:

The Ingredients

Ingredient	Amount	Notes
Boneless, skinless chicken breasts	1.5 lbs	Slice thin against the grain
Bell peppers (mixed colors)	3 large	Red, yellow, orange for sweetness
Red onion	1 large	Sliced into half-moons
Olive oil	3 tbsp	Avocado oil works great too
Chili powder	1.5 tsp	The backbone of the seasoning
Cumin	1 tsp	Earthy and essential
Smoked paprika	1 tsp	Adds that smoky depth
Garlic powder	½ tsp
Onion powder	½ tsp
Salt & black pepper	To taste
Lime juice	1 lime	Fresh, always

Pro Tips Before You Start

• Slice everything thin and uniform. This is the one non-negotiable. Thick chunks won't cook evenly — and nobody wants a raw onion situation.
• Don't crowd the pan. Spoiler alert: if your veggies are piled on top of each other, they'll steam instead of roast. Use two pans if needed.
• Pat the chicken dry before seasoning. Moisture is the enemy of that beautiful caramelized edge.

How to Make Sheet Pan Chicken Fajitas (Step by Step)

This is where it gets satisfying. Follow these steps and future you will thank you — especially when you're eating delicious fajitas with basically one dish to wash.

Step 1: Preheat and Prep

Preheat the oven to 425°F (220°C). Line a large rimmed baking sheet with foil or parchment for easy cleanup. Do yourself a favor and don't skip this step.

Step 2: Make the Seasoning

In a small bowl, mix together:

• Chili powder, cumin, smoked paprika, garlic powder, onion powder, salt, and pepper

This homemade blend takes 30 seconds and tastes so much better than the packet. No judgment if you've used the packet before — everyone has.

Step 3: Season and Arrange

Add the sliced chicken, peppers, and onion to the sheet pan. Drizzle with olive oil and squeeze half the lime over everything. Sprinkle the spice blend on top and toss until everything is evenly coated.

Spread it all out in a single layer. This is the moment that makes or breaks the recipe.

Step 4: Roast

Roast at 425°F for 20–25 minutes, flipping the chicken halfway through. The chicken should reach an internal temp of 165°F, and the peppers should have those gorgeous charred edges.

Step 5: Serve

Squeeze the remaining lime over the top and pile everything into warm flour or corn tortillas. Add your toppings and dig in.

🌮 Topping Ideas

• Sour cream or Greek yogurt
• Fresh guacamole or sliced avocado
• Shredded cheese
• Pico de gallo or fresh salsa
• Pickled jalapeños
• Fresh cilantro

• Spice it up: Add cayenne or chipotle powder to the seasoning blend
