Ingredients and Essential Kitchen Equipment

Ingredients

For the seasoning, steak, and veggies, you will need:

Seasoning:

• 1 tablespoon chili powder
• 1 teaspoon dried oregano
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1 teaspoon sea salt
• ½ teaspoon paprika
• ½ teaspoon ground cumin
• ¼ teaspoon ground black pepper

Steak Fajitas:

• ¼ cup olive oil, divided
• 1 tablespoon coconut aminos
• 1 tablespoon lime juice
• 1.5–2 lb flank or skirt steak
• 3 bell peppers (red, yellow, or orange), sliced thinly
• 1 medium red onion, sliced thinly
• Freshly chopped cilantro, for garnish
• Siete tortillas warmed, for serving

These ingredients blend together to create a rich marinade for the steak and a complementary seasoning for the vegetables.

Essential Kitchen Equipment

Before you begin, gather the following tools to ensure a smooth cooking experience:

• Large Baking Sheet: Preferably rimmed to contain any juices and ensure even cooking.
• Parchment Paper: To line your baking sheet for easy cleanup.
• Mixing Bowls: A small bowl for the spice mixture and a larger one for marinating the steak.
• Measuring Cups and Spoons: For accurate measurement of oil, lime juice, and spices.
• Knife and Cutting Board: Essential for slicing the steak, bell peppers, and red onion.
• Tongs: For flipping the steak and stirring the vegetables on the sheet pan.
• Instant-Read Thermometer (optional): To check the doneness of your steak.
• Aluminum Foil (optional): In case you need to cover the dish briefly during resting.
• Serving Platters: For a beautiful presentation once your dish is ready.

Step-by-Step Recipe Instructions

1. Preheat and Prep

Begin by preheating your oven to 450°F. While the oven heats up, line a large baking sheet with parchment paper. This step ensures your steak and vegetables cook evenly and helps with easy cleanup later.

2. Marinate the Steak

In a small bowl, combine all of the spices for the seasoning: chili powder, dried oregano, garlic powder, onion powder, sea salt, paprika, ground cumin, and ground black pepper. Divide this spice mixture in half, setting aside one half for later use with the vegetables.

In a large bowl or glass dish, mix together 2 tablespoons of olive oil, 1 tablespoon coconut aminos, and 1 tablespoon lime juice. Add the steak (1.5–2 lb flank or skirt steak) to the marinade. Flip the steak a few times so it gets thoroughly coated in the spice-infused oil mixture. Let the steak marinate briefly while you prepare the vegetables; even 10-15 minutes can enhance the flavor significantly.

3. Season the Vegetables

While the steak is marinating, arrange the sliced bell peppers and red onion on the prepared baking sheet. Drizzle the vegetables with 2 tablespoons of olive oil, then sprinkle with the remaining half of the spice mixture. Use your hands to massage the oil and spices into the veggies evenly. This ensures every slice is bursting with flavor when roasted.

4. Assemble on the Sheet Pan

Move the seasoned vegetables to the outer edge of the baking sheet, making space in the center. Place the marinated steak in the center of the pan. This strategic placement allows the steak to cook evenly while the vegetables roast around it.

5. Bake and Broil

Place the sheet pan in the preheated oven and bake for 14-16 minutes. This initial baking phase cooks the steak to a nice medium doneness while simultaneously roasting the vegetables. For the final touch, switch your oven to the broiler on high and broil the steak and vegetables for an additional 2 minutes. This step is crucial for achieving a beautifully seared exterior on the steak and a slight char on the vegetables. For those using a meat thermometer, aim for an internal temperature of 130°F for medium-rare or 135°F to 145°F for medium doneness.

6. Rest and Slice

Once the steak is done, remove the sheet pan from the oven and let the steak rest on the pan for 10 minutes. Resting allows the juices to redistribute throughout the meat, ensuring a tender, juicy result. After resting, slice the steak thinly against the grain to maximize tenderness.

7. Garnish and Serve

Sprinkle freshly chopped cilantro over the sliced steak. Serve the steak and vegetables in warm Siete tortillas. For added indulgence, consider serving with a side of guacamole, sour cream, or a squeeze of fresh lime juice. These fajitas are best enjoyed immediately while hot and bursting with flavor.

Tips, Shortcuts, and Recipe Variations

Important Notes:

• Marination Time: Even a short marination (10-15 minutes) significantly enhances the flavor of the steak. If time permits, let it marinate for up to 30 minutes for deeper flavor penetration.
• Vegetable Uniformity: Ensure that the bell peppers and onions are sliced evenly to guarantee uniform cooking and a balanced texture.
• Broiler Watch: Keep a close eye on your dish during the broiling stage. The high heat can quickly overcook or burn the steak and vegetables if left unattended.

Tips and Shortcuts:

• Prepping in Advance: You can prepare the spice mixture and slice the vegetables ahead of time. Store them in the refrigerator until you’re ready to cook.
• Using a Meat Thermometer: For perfectly cooked steak every time, use an instant-read thermometer to check for your desired level of doneness.
• Even Cooking: Spread the vegetables out in a single layer on the sheet pan to ensure they roast rather than steam.
• Clean-Up Ease: Lining your baking sheet with parchment paper not only prevents sticking but also makes cleanup a breeze.

Recipe Variations:

• Alternative Protein: Substitute steak with boneless, skinless chicken breasts or thighs for a lighter version of fajitas.
• Extra Veggies: Add other vegetables such as zucchini, mushrooms, or even cherry tomatoes to diversify the flavors and textures.
• Spicy Kick: If you enjoy extra heat, increase the amount of chili powder or add a dash of cayenne to the vegetable seasoning.
• Tortilla Options: While Siete tortillas are recommended for a gluten-free option, you can use any soft flour tortilla or corn tortilla depending on your dietary preferences.
• Saucy Fajitas: For a saucier version, drizzle a bit of lime crema or your favorite salsa over the fajitas before serving.

How to Store and Reheat Leftovers

Storing Leftovers:

If you have any leftovers from your Sheet Pan Steak Fajitas, store them in an airtight container in the refrigerator. They will keep well for up to 3 days. Keep the steak and vegetables separate from the tortillas to maintain their texture. For best results, reheat the steak and vegetables before assembling the fajitas.

Reheating Instructions:

• Stovetop: Gently reheat the steak and vegetables in a skillet over medium heat. Add a splash of water if necessary to prevent sticking.
• Microwave: Place a portion in a microwave-safe dish, cover loosely, and heat in 30-second intervals, stirring in between until warmed through.
• Oven: For a crispier finish, reheat the steak and vegetables in a preheated oven at 350°F for about 10 minutes, then reassemble the fajitas just before serving.

Food and Drink Pairings

Ideal Food Pairings:

• Rice or Beans: Serve your fajitas over a bed of Spanish rice or with a side of refried beans for a complete meal.
• Salad: A fresh side salad, such as a classic Caesar or a mixed greens salad with a zesty vinaigrette, provides a refreshing counterbalance to the rich, savory fajitas.
• Grilled Corn: Add a side of grilled corn on the cob for extra sweetness and a fun twist on the meal.

Beverage Pairings:

• Margaritas: A classic margarita with a tangy lime kick perfectly complements the bold flavors of steak fajitas.
• Light Beer: A crisp lager or pilsner works well to refresh your palate between bites.
• Iced Tea: A glass of unsweetened iced tea with a slice of lemon offers a cool, hydrating contrast.
• Sparkling Water: For a non-alcoholic option, try sparkling water with a splash of lime or grapefruit for a refreshing finish.

Frequently Asked Questions (FAQs)

Q: Can I use a different cut of steak for this recipe?

A: Yes, while flank or skirt steak is ideal due to their robust flavor and quick cooking time, you can use other cuts like sirloin if preferred. Just be mindful of the cooking time, as thicker cuts may require a few extra minutes to reach your desired doneness.

Q: How do I prevent the vegetables from becoming mushy?

A: Ensure that the vegetables are sliced evenly and arranged in a single layer on the sheet pan. Tossing them with olive oil and seasoning before roasting helps to crisp them up, while avoiding overcrowding the pan prevents steaming.

Q: Can I prepare this recipe ahead of time?

A: Yes, you can prepare the steak marinade and pre-sliced vegetables ahead of time. Store them in the refrigerator until you’re ready to cook. However, for the best texture, it’s recommended to assemble and cook the fajitas just before serving.

Q: What if I don’t have an Instant Pot?

A: This recipe is designed for the oven, so you don’t need an Instant Pot. The sheet pan method is perfect for achieving even cooking and is ideal for a busy weeknight dinner.

Q: How can I adjust the spice level?

A: Feel free to modify the spice mixture. If you prefer a milder flavor, reduce the amount of chili powder and omit the cayenne. For a spicier version, add more chili powder or a diced jalapeño to the marinade.

Q: What is the best way to serve the fajitas?

A: Serve the sliced steak and roasted vegetables in warmed tortillas, topped with fresh cilantro, and accompanied by guacamole, sour cream, or your favorite salsa for added flavor.
