  • Cuisine: Mexican-American, Tex-Mex

Ingredients

Scale
  • 2 lbs chicken breasts, sliced
  • 3 bell peppers, sliced
  • 2 large onions, sliced
  • 3 tbsp olive oil
  • 2 limes, juiced
  • 2 tsp chili powder
  • 1 tsp cumin
  • 1 tsp paprika
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • ½ tsp oregano
  • 1 tsp salt
  • ½ tsp black pepper
  • 1618 tortillas
  • Optional toppings: cilantro, sour cream, guacamole, etc.

Instructions

Prep (15 minutes – The Foundation of Flavor):

    1. Preheat Oven (Getting Ready to Roast): Preheat your oven to 425°F (218°C). Preheating the oven ensures that the chicken and vegetables cook evenly and develop a nice char.
    2. Prepare Baking Sheet (The Easy Cleanup): Line a large sheet pan with parchment paper or foil for easy cleanup. Parchment paper prevents the food from sticking to the pan and makes cleanup a breeze. Foil is also a good option, but parchment paper is generally preferred for baking.
    3. Slice Chicken (The Protein Prep): Slice the chicken breasts into ¼-inch strips. This ensures even cooking and makes them perfect for fajitas. You can also buy pre-sliced chicken strips to save time.
    4. Slice Vegetables (The Veggie Power): Cut the bell peppers and onions into even strips, similar in size to the chicken. Uniformly sized pieces will cook at the same rate.
    5. Mix Seasoning (The Flavor Booster): In a small bowl, mix all the fajita seasoning ingredients together until well combined. This homemade seasoning blend is far superior to store-bought versions and allows you to control the level of spice.

Season and Arrange (5 minutes – The Flavor Infusion):

    1. Combine Ingredients (The Flavor Party): Place the sliced chicken and vegetables on the prepared sheet pan.
    2. Drizzle and Sprinkle (The Flavor Shower): Drizzle the chicken and vegetables with olive oil and lime juice. This helps the seasoning adhere and adds moisture. Then, sprinkle the fajita seasoning mixture evenly over everything, ensuring that all the chicken and vegetables are well coated.
    3. Toss and Spread (The Even Distribution): Toss everything together thoroughly to coat evenly, making sure that all the chicken and vegetables are well seasoned. Spread the mixture in a single layer on the sheet pan, ensuring nothing overlaps. Overlapping can cause the ingredients to steam instead of roast, leading to less flavorful and less crispy fajitas.

Cook (20-25 minutes – The Magic Happens):

    1. Bake (The Roasting Process): Bake the sheet pan chicken fajitas in the preheated oven at 425°F (218°C) for 20-25 minutes.
    2. Stir (The Even Cooking): Stir the mixture halfway through cooking to ensure even browning and prevent sticking. This also helps the vegetables to caramelize and the chicken to cook through evenly.
    3. Check for Doneness (The Temperature Check): Cook until the chicken reaches an internal temperature of 165°F (74°C). This is crucial for food safety. Use a meat thermometer to check the temperature – insert it into the thickest part of a chicken strip.
    4. Optional Broil (The Final Char): For extra char and a slightly smoky flavor, broil the fajitas for 2-3 minutes at the end of cooking. Keep a close eye on them to prevent burning!

Serve (The Grand Finale):

    1. Warm Tortillas (The Perfect Wrap): Warm the tortillas according to package directions. You can warm them in a skillet, microwave, or oven. Warming the tortillas makes them more pliable and prevents them from tearing when you fill them.
    2. Assemble (The Fun Part): Assemble the fajitas with the cooked chicken and vegetables. Let everyone customize their own fajitas with their favorite toppings.
    3. Add Toppings (The Flavor Explosion): Add your desired toppings, such as fresh cilantro, sour cream or Greek yogurt, guacamole or diced avocado, pico de gallo or salsa, shredded cheese, and lime wedges. Toppings add a burst of fresh flavor, creamy texture, and extra richness to the fajitas.
    4. Squeeze Lime (The Citrus Burst): Squeeze fresh lime juice over the assembled fajitas for a final burst of citrusy goodness. Lime juice brightens up the flavors and adds a refreshing tang.
    5. Serve Immediately (The Best Enjoyment): Serve the fajitas immediately while they’re hot and the tortillas are warm. This is when they taste their absolute best!

Notes

  • Slice ingredients evenly.
  • Don’t overcrowd the pan.
  • Check chicken for doneness.
  • Serve with desired toppings.

Ingredients: The Stars of the Show

For the Fajitas: The Main Event

  • 2 lbs boneless, skinless chicken breasts, sliced into ¼-inch strips – Chicken breasts are a lean and versatile protein source. Slicing them into thin strips ensures even cooking and makes them perfect for wrapping in tortillas.
  • 3 bell peppers (a mix of red, yellow, and green), sliced – Bell peppers add vibrant color, a touch of sweetness, and a healthy dose of vitamins to the fajitas. Using a variety of colors makes the dish visually appealing.
  • 2 large onions, sliced – Onions add a savory depth of flavor and caramelize beautifully during roasting.
  • 3 tablespoons olive oil – Olive oil helps to coat the chicken and vegetables, preventing them from sticking to the pan and adding a touch of richness.
  • 2 limes, juiced – Fresh lime juice adds a bright, citrusy tang that balances the other flavors and brightens up the dish.
  • 16-18 small flour or corn tortillas – Tortillas are the vessel for enjoying your delicious fajitas. Use your favorite type – flour tortillas are softer and more pliable, while corn tortillas have a slightly nuttier flavor.

For the Fajita Seasoning: The Flavor Bomb

  • 2 teaspoons chili powder – Chili powder adds a warm, slightly smoky flavor.
  • 1 teaspoon ground cumin – Cumin adds an earthy, slightly pungent flavor that is characteristic of Mexican cuisine.
  • 1 teaspoon paprika – Paprika adds a subtle sweetness and a touch of color. You can use sweet or smoked paprika.
  • 1 teaspoon garlic powder – Garlic powder adds a pungent, savory flavor.
  • 1 teaspoon onion powder – Onion powder adds a subtle sweetness and depth of flavor.
  • ½ teaspoon oregano – Oregano adds a slightly peppery, herbaceous flavor.
  • 1 teaspoon salt – Salt enhances the flavors of all the other ingredients.
  • ½ teaspoon black pepper – Black pepper adds a touch of heat and complexity.

Optional Toppings: The Finishing Touches

  • Fresh cilantro, chopped – Fresh cilantro adds a bright, herbaceous flavor.
  • Sour cream or Greek yogurt – Sour cream or Greek yogurt adds a creamy tang.
  • Guacamole or diced avocado – Guacamole or diced avocado adds richness and healthy fats.
  • Pico de gallo or salsa – Pico de gallo or salsa adds a fresh, vibrant flavor and a touch of heat.
  • Shredded cheese (cheddar, Monterey Jack, etc.) – Shredded cheese adds a melty, cheesy goodness.
  • Lime wedges – Extra lime wedges for squeezing over the finished fajitas add a final burst of citrus.

Alternatives and Flexibility: Making it Your Own

  • Protein Powerhouse: You can substitute the chicken breasts with chicken thighs (for a richer flavor), shrimp (for a faster cooking time), steak (for a more substantial meal), or even tofu (for a vegetarian option).
  • Veggie Variety: Feel free to add other vegetables to the sheet pan, such as sliced mushrooms, zucchini, poblano peppers, or even corn kernels. The more veggies, the merrier!
  • Tortilla Time: Use your favorite type of tortillas – flour, corn, or even low-carb options. You can also use lettuce wraps for a low-carb alternative.
  • Spice It Up: Add a pinch of cayenne pepper, a few dashes of hot sauce, or even some chopped jalapeños to the seasoning mix for a spicier kick. You can also add a pinch of smoked paprika for a smoky flavor.

Beginner Tips and Notes: Words of Wisdom

  • Even Slicing (The Key to Consistency): Slicing the chicken and vegetables into uniform strips is crucial for even cooking. Try to keep the pieces roughly the same size so they cook at the same rate. This will prevent some pieces from being overcooked while others are undercooked.
  • Don’t Overcrowd (The Roasting Rule): Avoid overcrowding the sheet pan, as this can cause the ingredients to steam instead of roast, resulting in less flavorful and less crispy fajitas. If your sheet pan isn’t large enough, use two sheet pans instead of trying to cram everything onto one.
  • Checking for Doneness (The Temperature Gauge): A meat thermometer is your best friend when cooking chicken. Make sure it reaches an internal temperature of 165°F (74°C) to ensure it’s cooked through and safe to eat. Insert the thermometer into the thickest part of a chicken strip.
  • Flavor Adjustments (The Personal Touch): Feel free to adjust the seasoning mix to your liking. Add more or less of any of the spices, or try adding other spices like smoked paprika, cayenne pepper, or cumin. You can also add a pinch of sugar to balance the flavors.

Serving Suggestions: The Perfect Pairings

These sheet pan chicken fajitas are incredibly versatile and can be served with a variety of toppings and sides.

Complementary Sides (The Delicious Additions):

  • Rice and Beans (The Classic Combo): Mexican rice or cilantro lime rice and black beans or refried beans are classic accompaniments to fajitas. They add a hearty and satisfying element to the meal.
  • Salad Sensation (The Refreshing Touch): A side salad with a light vinaigrette dressing adds a refreshing contrast to the richness of the fajitas. You can use mixed greens, romaine lettuce, or even shredded cabbage.
  • Salsa and Guacamole (The Flavor Boosters): Salsa and guacamole are essential fajita toppings. You can use store-bought versions or make your own from scratch.
  • Elote (The Mexican Street Corn): Grilled or roasted corn on the cob, also known as elote, is a delicious and festive addition to a fajita meal.

Storage Tips (Keeping it Fresh):

Store leftover chicken fajitas in an airtight container in the refrigerator for up to 3 days. Reheat them in a skillet or microwave. The chicken and vegetables can be stored separately if desired.
