Step-by-Step Instructions:
1. Prepare Your Steak and Veggies
Begin by slicing your steak thinly against the grain. This ensures tender results. Next, slice all your bell peppers and onion into thin strips.
2. Season the Steak
In a medium bowl, toss the sliced steak with 1 tablespoon of olive oil, 1 tablespoon of fajita seasoning, salt, and pepper. Make sure each piece is well coated.
3. Sauté the Vegetables
Heat the remaining 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the sliced bell peppers and onion. Sauté for 5-7 minutes, until they are tender-crisp. Remove the vegetables from the skillet and set aside.
4. Cook the Steak
Add the seasoned steak to the hot skillet in a single layer. Cook for 2-3 minutes per side, or until it reaches your desired doneness. Do not overcrowd the pan; cook in batches if necessary.
5. Combine and Finish
Once the steak is cooked, return the sautéed vegetables to the skillet with the steak. Sprinkle with the remaining 1 tablespoon of fajita seasoning and toss everything together to combine. Cook for another minute to heat through.
6. Serve Immediately
Serve your sizzling skillet steak fajitas with warm tortillas and your favorite toppings like sour cream, salsa, guacamole, and a squeeze of fresh lime. Enjoy this fantastic Mexican dinner recipe!
Variation Ideas:
- Spicy Fajitas: Add a pinch of cayenne pepper or sliced jalapeños to the skillet with the vegetables.
- Lime Fajitas: Marinate the steak in lime juice for 15-20 minutes before cooking for an extra zesty flavor.
- Cheesy Fajitas: Sprinkle shredded Monterey Jack or cheddar cheese over the fajitas just before serving.
Storage Instructions:
Store leftover Skillet Steak Fajitas in an airtight container in the refrigerator for up to 3-4 days. Reheat gently in a skillet over medium heat or in the microwave until warmed through. You might want to add a splash of water or broth to prevent them from drying out.
