Oven Baked Chicken (Or Pork) Fajitas: A Fiesta on a Sheet Pan!

The scent of sizzling fajitas always takes me back to summer evenings on my grandmother’s porch. She’d grill the peppers and onions until they were just slightly charred, and the aroma would drift through the neighborhood, beckoning everyone to gather around. We’d pile the fillings high onto warm tortillas, laughing and sharing stories as the sun dipped below the horizon. While she always made hers on the grill or skillet, this oven-baked method is a fantastic weeknight shortcut that delivers equally amazing flavor.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 25 minutes
• Total Time: 40 minutes
• Servings: 6
• Dietary Type: Gluten-Free adaptable

Ingredients

• 1 lb boneless, skinless chicken breast, cut into strips (or use pork tenderloin, cut into strips)
• 2 tablespoons vegetable oil
• 2 teaspoons chili powder
• 2 teaspoons cumin
• 1/2 teaspoon garlic powder
• 1/2 teaspoon dried oregano
• 1/4 teaspoon salt
• 1 (15 ounce) can diced tomatoes with green chilies, undrained
• 1 medium onion, sliced
• 1 large bell pepper, seeded and sliced into strips (any color works!)
• 12 flour tortillas (or corn tortillas for gluten-free)

Equipment Needed

• 13×9 inch baking dish
• Small bowl
• Measuring spoons
• Knife
• Cutting board

Instructions

1. Preheat your oven to 400 degrees Fahrenheit (200 degrees Celsius). Ensure the oven rack is in the middle position for even cooking.

2. Lightly grease a 13×9 inch baking dish. This prevents the fajita mixture from sticking and makes cleanup easier.

3. Place the chicken strips (or pork strips) in the prepared baking dish, spreading them out evenly.

4. In a small bowl, combine the vegetable oil, chili powder, cumin, garlic powder, dried oregano, and salt. Whisk together until a smooth paste forms. This spice blend creates the signature fajita flavor. For a shortcut, you can substitute this with a packet of pre-made fajita seasoning.

5. Drizzle the spice mixture evenly over the chicken/pork strips in the baking dish.

6. Using your hands or a spoon, stir the chicken/pork to ensure it is thoroughly coated with the spice mixture. This is crucial for even flavoring.

7. Add the diced tomatoes with green chilies (undrained), sliced onion, and bell pepper strips to the baking dish.

8. Stir all the ingredients together until the chicken/pork and vegetables are well combined and evenly distributed in the dish. The tomatoes will release some liquid during cooking, which helps create a flavorful sauce.

9. Bake uncovered in the preheated oven for 20-25 minutes, or until the chicken/pork is cooked through and the vegetables are tender. The internal temperature of the chicken should reach 165 degrees Fahrenheit (74 degrees Celsius), and the pork should reach 145 degrees Fahrenheit (63 degrees Celsius). Use a meat thermometer to ensure doneness. If using pork, keep a close eye and add a little water to the bottom of the pan if it appears to be drying out.

10. While the fajitas are baking, warm the flour tortillas. You can warm them in a dry skillet over medium heat, wrapped in foil in the oven, or even microwaved briefly wrapped in a damp paper towel. Warming the tortillas makes them more pliable and prevents them from cracking when filled.

11. Once the chicken/pork is cooked and the vegetables are tender, remove the baking dish from the oven. Let it rest for a few minutes before serving.

12. Serve the oven-baked fajita mixture immediately on warm tortillas. Offer a variety of desired toppings alongside, such as sour cream, lettuce, black beans, Spanish rice, corn, guacamole, salsa, and refried beans.

Expert Tips & Tricks

• For a smokier flavor, broil the fajita mixture for the last few minutes of cooking. Keep a close eye on it to prevent burning.
• If you prefer a sweeter flavor, add a tablespoon of brown sugar or honey to the spice mixture.
• To save time, you can prep the ingredients the night before. Slice the chicken/pork and vegetables, mix the spices, and store everything separately in the refrigerator. Then, simply assemble and bake when ready.
• If you don’t have diced tomatoes with green chilies, you can substitute regular diced tomatoes and add a pinch of red pepper flakes for heat.
• Feel free to add other vegetables to the mix, such as mushrooms, zucchini, or jalapeños.
• To reduce the clean up, try lining the baking dish with foil.

Serving & Storage Suggestions

Serve the oven-baked fajitas immediately while they are hot and the tortillas are warm. Arrange the toppings in separate bowls so guests can customize their fajitas. Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat the fajita mixture in a skillet over medium heat or in the microwave. You can also freeze leftovers for up to 2-3 months. Thaw completely before reheating.
