Ah, sheet pan fajitas! Just the thought of those sizzling peppers and onions takes me back to the family barbecues of my childhood—where the air was filled with laughter and a hint of charred goodness. You know, sometimes the simplest meals bring the most joy, like this one, which practically cooks itself while you catch up on that show everyone’s been raving about.
Steps
- Preheat your oven to 425°F (220°C) and lightly grease a large sheet pan. Slice the chicken breast against the grain into 1/2-inch thick strips and cut the bell peppers and onion into similar-sized strips.
- Arrange the vegetables evenly on the prepared sheet pan, then place the chicken strips on top. In a small bowl, mix together the fajita seasoning ingredients.
- Sprinkle most of the fajita seasoning over the chicken and a bit over the vegetables. Mince the garlic and spread it over the chicken, then drizzle the entire pan with oil.
- Toss all the ingredients on the pan to coat them evenly with the seasoning and oil. Spread everything out into a single layer and bake for 15-20 minutes, until the chicken is fully cooked.
- During the last 5 minutes of baking, wrap the tortillas in foil and place them in the oven to warm. Once done, remove the sheet pan from the oven and squeeze fresh lime juice over the chicken and vegetables.
- Sprinkle chopped cilantro over the cooked fajitas, then serve them in warm tortillas. Add desired toppings such as sour cream, guacamole, or salsa before enjoying.
