- 1½ lbs boneless skinless chicken breasts, sliced into strips
- 3 bell peppers, sliced
- 1 large onion, sliced
- 2 tbsp olive oil
- Juice of 1 lime
Fajita Seasoning
- 2 tsp chili powder
- 1 tsp paprika
- 1 tsp ground cumin
- 1 tsp garlic powder
- ½ tsp onion powder
- ½ tsp dried oregano
- 1 tsp salt
- ½ tsp black pepper
Step 1: Prep the IngredientsStart by slicing the chicken into thin strips. After that, cut the bell peppers and onions into similar-sized slices. Keeping everything roughly the same size helps the ingredients cook evenly.If you've ever ended up with overcooked vegetables and undercooked chicken, uneven slicing is often the culprit. Therefore, for best results, try to keep the chicken and vegetables close in thickness. Step 2: Mix the SeasoningNext, combine all the spices in a small bowl. Once the spices are added, stir them well so the flavors distribute evenly.Store-bought fajita seasoning can work in a pinch. However, homemade seasoning gives you better control over salt, spice, and overall flavor. Step 3: Toss Everything TogetherAdd the chicken, peppers, and onions to a large mixing bowl. Then, pour in the olive oil, lime juice, and seasoning blend.After everything is in the bowl, toss until the chicken and vegetables are evenly coated. Don’t rush this step, because a good coating means every bite delivers flavor. Step 4: Spread on a Sheet PanTransfer the mixture to a large rimmed baking sheet. Next, spread the ingredients into a single layer.This step matters more than most people realize. When ingredients are crowded together, they steam instead of roast. On the other hand, when they have enough space, they brown more easily and develop better texture.As a result, you get golden edges, caramelized vegetables, and deeper fajita flavor. Step 5: RoastBake at 425°F for 18–22 minutes. During this time, the chicken should cook through while the vegetables become tender with slightly browned edges.For food safety, the chicken should reach an internal temperature of 165°F. If you want more color, switch the oven to broil for the final 2–3 minutes.That little extra step creates the closest thing to restaurant-style fajitas you'll get without firing up a grill. Step 6: Finish and ServeOnce the fajitas are done, remove the pan from the oven. Then, squeeze fresh lime juice over everything and sprinkle with chopped cilantro.Finally, serve the chicken and vegetables with warm tortillas and your favorite toppings. At this point, the smell alone will probably bring everyone into the kitchen before you even call them.
