Why You'll Love This Recipe
About the Ingredients
1 1/2 lbs (680g) boneless, skinless chicken breasts, sliced into 1/2-inch strips
Chicken breasts work great, but thighs are even juicier. If using thighs, adjust cooking time slightly.
3 bell peppers (mix of red, yellow, orange), sliced into 1/2-inch strips
Use any color you like; green peppers are more bitter, so I prefer the sweeter reds and yellows.
1 large red onion, sliced into 1/2-inch wedges
Red onion adds a nice bite; if you're not a fan, use a yellow onion for a milder flavor.
2 tbsp olive oil
Extra virgin olive oil is great, but any neutral oil like avocado oil works too.
2 tsp chili powder
Smoked paprika adds a deeper smoky flavor if you have it; adjust to taste.
1 1/2 tsp ground cumin
Cumin is essential for that fajita flavor; if you run out, use a little extra chili powder.
1 tsp smoked paprika
Smoked paprika gives a lovely smoky depth; regular paprika works if that's all you have.
1 tsp garlic powder
Fresh minced garlic can be used, but add it in the last 5 minutes to avoid burning.
1 tsp salt
Use kosher salt for even seasoning; adjust to your taste.
1/2 tsp black pepper
Freshly ground black pepper is best for flavor.
8 small flour tortillas (6-inch)
Corn tortillas are also great for a gluten-free option; warm them before serving.
Optional toppings: sour cream, salsa, shredded cheese, chopped cilantro, lime wedges
Get creative! These are just suggestions.
Tips & Tricks
Don't overcrowd the pan
Spread everything in a single layer so the veggies char, not steam.
Slice evenly
Try to cut chicken and veggies similar in size so they cook at the same rate.
Preheat the pan
Place the sheet pan in the oven while it preheats for a quick sear.
Pro Tips
Step-by-Step Instructions
1. Preheat and Prep Pan
Preheat your oven to 400°F (200°C). Place a large sheet pan in the oven while it heats up. This gives you a hot surface for better searing.
2. Mix the Spice Rub
In a small bowl, combine chili powder, cumin, smoked paprika, garlic powder, salt, and black pepper.
3. Toss Chicken and Veggies
In a large bowl, toss the chicken strips, bell peppers, and red onion with olive oil and the spice rub until everything is well coated.
4. Spread on Hot Pan
Carefully remove the hot sheet pan from the oven. Spread the chicken and vegetables in a single, even layer. Return the pan to the oven.
5. Roast Until Chicken is Done
Roast for 15 minutes. Then, switch to broil for 2-3 minutes to get charred edges. Check that the chicken is cooked through—it should reach 165°F (74°C) and the veggies should be tender-crisp with browned edges.
6. Warm the Tortillas
While the fajitas roast, warm the tortillas in a dry skillet over medium heat, about 30 seconds per side, or wrap in foil and heat in the oven for 5 minutes.
7. Serve and Enjoy
Spoon the chicken and veggies onto warm tortillas. Add your favorite toppings and a squeeze of lime. Serve immediately.
Delicious Variations
Swap the protein
Use shrimp (reduce cooking time to 8-10 minutes) or sliced steak (cook to your preferred doneness).
Add extra veggies
Include sliced zucchini, mushrooms, or even corn for more texture.
Make it a bowl
Skip the tortillas and serve over rice or salad for a low-carb option.
