How to Make One-Pan Chicken Fajitas
Creating delicious One-Pan Chicken Fajitas is simple, quick, and mess-free. Here’s a step-by-step guide to making this flavorful dish:
Preheat the Oven
Preheat your oven to 425°F (220°C) and line a large baking sheet with parchment paper or foil for easy cleanup.
Slice the Ingredients
Thinly slice the chicken breasts, bell peppers, and onions into even strips to ensure they cook at the same rate.
Season Everything
In a large mixing bowl, combine the chicken and vegetables. Drizzle with olive oil and sprinkle with fajita seasoning. Toss well to coat everything evenly.
Arrange on the Baking Sheet
Spread the seasoned chicken and vegetables evenly on the prepared baking sheet in a single layer. This helps them roast evenly.
Bake to Perfection
Place the baking sheet in the preheated oven and bake for 20-25 minutes, stirring halfway through to ensure even cooking. The chicken should be cooked through, and the vegetables should be tender and slightly caramelized.
Warm the Tortillas
While the fajitas are baking, warm your tortillas in a dry skillet, microwave, or oven for a soft, pliable texture.
Serve and Enjoy
Once done, remove the pan from the oven and squeeze fresh lime juice over the top. Serve with tortillas and your choice of toppings like sour cream, guacamole, or shredded cheese.
Tips for Perfect One-Pan Chicken Fajitas
Cut Ingredients Evenly
To ensure even cooking, slice the chicken and vegetables into uniform strips.
Don’t Overcrowd the Pan
Spread everything in a single layer to allow proper roasting and caramelization. Overcrowding will result in steaming instead of roasting.
Use Fresh Spices
Opt for fresh, aromatic spices or a high-quality fajita seasoning blend for the best flavor.
High Heat is Key
Baking at 425°F ensures the chicken stays juicy and the vegetables get a delicious char.
Customize to Taste
Adjust the seasoning to your preferred spice level, and feel free to add extras like smoked paprika or cayenne pepper for more heat.
