Recipe For Leftover Flank Steak

Step 1: Prep Your Ingredients

Start by thinly slicing your leftover flank steak against the grain to ensure tenderness. Then, slice your onion and bell pepper into thin strips. Mince the garlic cloves finely. Having all your ingredients prepped and ready to go makes the cooking process smoother and more enjoyable.

Step 2: Sauté the Vegetables

Heat the olive oil in a large skillet over medium heat. Add the sliced onions and bell peppers, sautéing until they start to soften, about 5 minutes. Add the minced garlic, cumin, and smoked paprika, stirring well to coat the vegetables in the spices. The aroma at this stage should be irresistible.

Step 3: Add the Steak

Introduce the sliced flank steak to the skillet, mixing it with the vegetables and spices. Pour in the beef broth to add moisture and depth of flavor. Let everything simmer together for about 3-4 minutes, allowing the steak to warm through and absorb the flavors.

Step 4: Warm the Tortillas

While the steak mixture is simmering, warm your tortillas in a dry skillet over medium heat for about 30 seconds on each side. This step is crucial for achieving that perfect, pliable texture that makes wrapping your fajitas so much easier.

Step 5: Assemble and Serve

Divide the steak and vegetable mixture evenly among the warmed tortillas. If using, sprinkle shredded cheese on top. Fold the tortillas over the filling and serve immediately. Enjoy the fruits of your minimal labor with maximum flavor.

Tips and Tricks

For an extra kick, consider adding a diced jalapeño to the vegetable mix. If you’re not a fan of beef broth, chicken or vegetable broth works just as well. To make this dish even quicker, use pre-sliced onions and bell peppers from the grocery store. For those who love a smoky flavor, a dash of liquid smoke can elevate the dish. Lastly, if you’re serving a crowd, keep the tortillas warm in a low oven until ready to serve.

Recipe Variations

  • Turn it into a salad by serving the steak and vegetable mixture over a bed of greens with your favorite dressing.
  • Make it a stir-fry by adding more vegetables like mushrooms and snap peas, and serve over rice.
  • Create a hearty soup by adding more broth, diced tomatoes, and beans to the steak mixture.
  • For a low-carb option, serve the mixture in lettuce wraps instead of tortillas.
  • Add a creamy element by mixing in a dollop of sour cream or Greek yogurt before serving.

Yes, simply use gluten-free tortillas or serve the mixture over rice or quinoa for a completely gluten-free meal. Always check the labels on your broth and spices to ensure they’re gluten-free as well.
