HideWhat 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.

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
