Grab your skillet, it's time to make sizzling hot steak fajitas! I have a flavorful marinade that pairs nicely with the colorful mix of sauteed vegetables.
Ingredients
Steak Marinade
1pound(454g)skirt steak, or flank steak, sirloin, flat iron, or hanger steak
Make the Marinade - In a medium bowl whisk together olive oil, soy sauce, jalapeno, garlic, cumin, salt, pepper, and lime zest. Remove ¼ cup and transfer it to a small bowl. Whisk in lime juice to the reserved marinade and set aside.
Marinate the Steak - Add the steak to a large plastic bag or casserole dish. From the medium bowl, pour the remaining marinade over the meat, and flip several times to coat. Marinate for 30 minutes, flipping halfway through.
Sear the Meat - Heat a large cast iron skillet over medium-high heat. Add 1 tablespoon of olive oil to the pan. Shake off the excess marinade from the steak, and scrape off any garlic and jalapeno to prevent burning. Pat dry with a paper towel. Carefully add steak to the hot pan.Sear without moving until the surface browns, about 2 to 3 minutes. Flip and cook until the internal temperature reaches 120 to 125ºF (49 to 52ºC) for medium-rare, about 2 to 4 minutes depending on the thickness. Transfer to a cutting board, and cover with foil. Allow it to rest for 10 minutes before slicing.
Cook the Vegetables - Add 1 tablespoon of olive oil to the pan. Once hot, add the onions and saute for 1 minute. Add the zucchini, and saute for 1 minute. Add mushrooms, and saute for 1 minute. Add bell peppers, and saute for 2 minutes. Season with ½ teaspoon salt and ¼ teaspoon black pepper, and stir to combine. The vegetables should be crisp-tender.
Slice the Meat - Slice the steak across the grain, on a bias, into thin ¼-inch thick strips.
To Serve - Add the slices on top of the vegetables. Add the 1/4 cup of reserved marinade over the fajitas. Season with salt and pepper as desired. Garnish with chopped cilantro leaves. Serve immediately with warmed tortillas and desired toppings.
Notes
Serving Size: 1 tortilla plus steak fajitas filling.
Marinating Duration: The steak can be refrigerated and marinated for up to 24 hours.
MAKE IT GLUTEN-FREE AND WHOLE 30: Use gluten-free tamari or coconut aminos instead of soy sauce. For gluten-free use corn tortillas, or wrap in lettuce for Whole30.
