I remember the first time I made fajitas; it was a total mess! I had multiple pans going, smoke everywhere, and my family was practically eating in shifts. Ah, the joys of learning to cook! But then, a friend shared this sheet pan method, and it was a game-changer. Everything cooks together on one pan, making cleanup a breeze. Plus, the flavors meld beautifully as the veggies and protein roast in the oven's heat. Whats not to love? I even sometimes add a little tequila to the marinade for an extra kick – don't tell anyone!

The beauty of these sheet pan fajitas lies in their simplicity and adaptability. Feel free to use chicken, steak, shrimp, or even tofu as your protein. Mix and match your favorite bell pepper colors. Add a jalapeño for some heat! And don't forget the toppings! From classic sour cream and guacamole to salsa and pickled onions, the possibilities are endless. Are you team guac or team sour cream? I'm definitely guac!

Seriously, these are a lifesaver on busy evenings. I've even prepped the veggies and marinade the chicken the night before, making dinner even faster the next day. Imagine coming home after a long day and knowing dinner is just a sheet pan away. It's pure bliss, I tell you! And the aroma that fills the kitchen as they cook? Absolutely divine. Try them; you wont regret it…I promise!

🍽 Ingredients

📖 Instructions

  1. Preheat your oven to 400°F (200°C). Make sure the rack is in the middle position.
  2. Prepare the bell peppers and onions: Wash and slice 2 large bell peppers (any color) into 1/4-inch thick strips. Peel and slice 1 large onion into similar-sized strips. Aim for consistency so they cook evenly.
  3. Prepare the protein: If using chicken breasts (about 1.5 pounds), slice them thinly against the grain into strips. If using steak, ensure it's also sliced thinly. For shrimp, peel and devein about 1 pound.
  4. Make the fajita marinade: In a large bowl, whisk together 2 tablespoons of olive oil, 2 tablespoons of lime juice (freshly squeezed is best!), 1 tablespoon of fajita seasoning (store-bought or homemade), 1 teaspoon of chili powder, 1/2 teaspoon of cumin, 1/4 teaspoon of garlic powder, and a pinch of salt and pepper. Taste and adjust seasonings as needed.
  5. Marinate the protein and veggies: Add the sliced bell peppers, onions, and your chosen protein to the bowl with the marinade. Toss everything thoroughly to ensure it's evenly coated. Let it marinate for at least 15 minutes, or up to an hour in the refrigerator. The longer it marinates, the more flavorful it will be!
  6. Arrange on the sheet pan: Spread the marinated mixture in a single layer on a large baking sheet. If you have a rimmed baking sheet, that's ideal to prevent any juices from spilling.
  7. Bake the fajitas: Place the sheet pan in the preheated oven and bake for 20-25 minutes, or until the vegetables are tender-crisp and the protein is cooked through. The internal temperature of chicken should reach 165°F (74°C), and shrimp should be pink and opaque. Keep an eye on it – ovens vary!
  8. Broil for extra caramelization (optional): For extra color and a slightly charred flavor, broil the fajitas for the last 2-3 minutes, watching closely to prevent burning.
  9. Warm the tortillas: While the fajitas are baking, warm your tortillas. You can wrap them in foil and warm them in the oven, heat them in a dry skillet, or microwave them briefly. Warm tortillas are key to a great fajita experience!
  10. Serve and enjoy: Remove the sheet pan from the oven. Serve the fajitas immediately with warm tortillas and your favorite toppings. Garnishing with some fresh cilantro is always a win!
  11. Remember to serve with a smile! Because you deserve it for making such a quick and delcious meal!

📝 Notes

  • For spicier fajitas, add a pinch of cayenne pepper to the marinade.
  • Use your favorite store-bought fajita seasoning or make your own using a blend of chili powder, cumin, paprika, garlic powder, onion powder, oregano, and cayenne pepper.
  • Serve with your favorite toppings like guacamole, sour cream, salsa, shredded cheese, cilantro, and pickled onions.
