For the Homemade Fajita Seasoning (Optional)

- 1/4 teaspoon dried oregano

Step-by-Step Instructions
-
Step 1: Preheat and Prepare
Preheat your oven to 400°F (200°C). Lightly grease a large baking sheet or a 9×13 inch baking dish with a little olive oil or cooking spray. This will help prevent sticking and make cleanup even easier.
-
Step 2: Chop the Ingredients
Cut your boneless, skinless chicken breasts or thighs into uniform 1/2-inch strips. Next, slice your bell peppers and red onion into 1/4-inch strips. Try to keep the sizes similar so everything cooks evenly.
Small tip: Use a sharp knife for clean cuts, especially on the peppers and onions. This makes prepping quicker and safer.
-
Step 3: Season the Fajita Mix
In a large bowl, combine the sliced chicken, bell peppers, and red onion. Drizzle with 2 tablespoons of olive oil. Sprinkle the fajita seasoning, salt, and black pepper over the chicken and vegetables. Toss everything together really well with your hands or a large spoon until every piece is evenly coated.
Small tip: If you’re making your own seasoning, mix all the spices in a small bowl before adding them to the chicken and veggies for even distribution.
-
Step 4: Arrange on Baking Sheet
Spread the seasoned chicken and vegetable mixture in a single layer on your prepared baking sheet or dish. Make sure not to overcrowd the pan. If your pan is too full, use two baking sheets so the ingredients can roast instead of steam, ensuring a delicious char.
-
Step 5: Bake to Perfection
Place the baking sheet in the preheated oven. Bake for 25-30 minutes, or until the chicken is cooked through and the vegetables are tender-crisp and slightly charred at the edges. Give the mixture a stir halfway through the cooking time to ensure even browning.
Small tip: The chicken is done when it reaches an internal temperature of 165°F (74°C). Use a meat thermometer to be sure!
-
Step 6: Finish and Serve
Once baked, remove the pan from the oven. Squeeze fresh lime juice over the entire dish. This brightens all the flavors and adds a zesty finish. Garnish with fresh chopped cilantro, and serve immediately with your favorite toppings and warm tortillas.
Tips & Variations
- Gluten-Free Option: This recipe is naturally gluten-free! Just be sure to double-check that your store-bought fajita seasoning is certified gluten-free, or make your own using the recipe provided. Serve with corn tortillas or over rice for a complete meal.
- Vegan or Vegetarian Option: Easily transform this into a plant-based meal! Replace the chicken with 1.5 lbs of firm tofu (pressed and cubed), extra-firm tempeh, sliced portobello mushrooms, or canned black beans (drained and rinsed). Cook time might vary slightly.
- Add More Vegetables or Protein: Feel free to customize! Add sliced zucchini, corn kernels, or even a can of drained and rinsed black beans to the mix before baking. For more protein, you can increase the amount of chicken or add shrimp for a surf-and-turf fajita bake.
- Spicy Version: If you love a kick, add 1-2 chopped jalapeños or serrano peppers to the vegetable mix before baking. You can also increase the amount of cayenne pepper in your homemade seasoning, or drizzle with a dash of your favorite hot sauce after baking.
- Cheesy Topping: For an extra layer of deliciousness, sprinkle 1/2 cup of shredded Monterey Jack or cheddar cheese over the fajita mix during the last 5 minutes of baking. Let it melt until bubbly and slightly golden.
