The 25-Minute Sheet-Pan Chicken Fajitas (Fiesta Flavor, Minimal Effort)
When you want a dinner that feels like a celebration but you only have 25 minutes to spare, fajitas are the ultimate answer. However, restaurant fajitas are typically cooked in pools of soybean oil, turning a lean protein meal into a calorie bomb.
This Sheet-Pan Chicken Fajitas recipe brings all the smoky, sizzling Tex-Mex flavor straight to your kitchen with almost zero effort. By slicing everything up and tossing it onto one pan, the chicken breast stays incredibly juicy while the peppers and onions get beautifully caramelized under the high heat.

The Ingredients
- 1 lb (450g) Chicken breast, sliced into thin strips
- 3 large Bell peppers (mix red, yellow, and green), sliced into strips
- 1 large Yellow onion, sliced
- 1 tbsp Olive oil
- 1 tbsp Chili powder
- 1 tsp Ground cumin
- 1 tsp Garlic powder
- ½ tsp Smoked paprika
- To taste: Salt and black pepper
- For serving: Fresh lime wedges and low-carb tortillas or cilantro-lime rice
Step-by-Step Instructions
- Preheat the Oven: Crank your oven up to 425°F (220°C). High heat is the secret to getting those nice, charred restaurant edges on your vegetables.
- Toss and Season: Lay your sliced chicken strips, bell peppers, and onions directly onto a large baking sheet. Drizzle the olive oil over the top, then sprinkle the chili powder, cumin, garlic powder, smoked paprika, salt, and pepper evenly over everything.
- Mix Thoroughly: Use your hands or tongs to toss the ingredients together right on the pan until every strip of chicken and vegetable is coated in oil and spices. Spread it out into a flat, single layer.
- Bake to Perfection: Slide the pan into the oven and bake for 18 to 20 minutes, tossing halfway through. You'll know it's ready when the chicken is fully cooked through and the edges of the peppers look beautifully blistered.
- Serve Hot: Squeeze a fresh lime wedge over the entire sizzling sheet pan immediately upon removing it from the oven to lock in the juices. Wrap it up in your favorite warm tortillas and dig in!
