Ingredients Overview

This recipe calls for a handful of accessible ingredients that work in harmony to create depth and deliciousness in every bite.

Steak – Flank steak or skirt steak is ideal here. They cook quickly and absorb seasoning beautifully. Once seared, they develop a flavorful crust while staying juicy inside. If needed, sirloin can be used as a substitute.

Black Beans – Canned black beans add creamy texture and earthy richness. They also bring plant-based protein and fiber, making this dish more filling. Pinto beans are a fine swap if black beans aren’t available.

Bell Peppers – Use a mix of red, yellow, and green for the most visual and flavor impact. They become soft and slightly charred, adding a smoky sweetness that balances the savory meat and spices.

Onion – A classic component in fajitas, sliced red or yellow onion lends a touch of sweetness and depth. It softens and caramelizes, building the base flavor of the dish.

Garlic – Minced garlic brings sharp, aromatic warmth. Fresh is best, but garlic powder can work in a pinch.

Fajita Seasoning – A blend of chili powder, cumin, smoked paprika, oregano, and salt adds Tex-Mex personality. You can use store-bought or make your own.

Lime Juice – A finishing splash of fresh lime juice brightens the dish and lifts the smoky, savory notes. Lemon can be used in a pinch, but lime is more traditional.

Olive Oil – Used for sautéing the steak and veggies, it helps everything brown evenly and develop deep flavor. Avocado oil is a good high-heat alternative.

Fresh Cilantro (optional) – Sprinkled over the skillet before serving, it adds freshness and color. If you’re not a fan of cilantro, flat-leaf parsley is a milder alternative.

Step-by-Step Instructions

1. Prep the Ingredients
   Thinly slice the steak against the grain into bite-sized strips. Pat dry with paper towels and season with salt and half of the fajita seasoning. Drain and rinse the beans, slice the onions and peppers, and mince the garlic.

2. Sear the Steak
   Heat a tablespoon of oil in a large cast iron or nonstick skillet over medium-high heat. Once hot, add the steak in a single layer without overcrowding. Sear for 2–3 minutes on each side until browned and cooked to your liking. Remove and set aside on a plate, covering loosely with foil.

3. Sauté the Veggies
   In the same skillet, add a bit more oil if needed. Toss in the sliced peppers and onions, along with a pinch of salt and the rest of the fajita seasoning. Cook for about 5–7 minutes, stirring occasionally, until they start to soften and develop charred edges. Add the garlic and cook for another 30 seconds.

4. Add the Beans
   Stir in the black beans and let them warm through, about 2 minutes. Gently mash a few with the back of your spoon for extra creaminess and texture.

5. Combine Everything
   Return the steak and its juices to the skillet. Squeeze in the fresh lime juice and toss everything together to coat. Taste and adjust seasoning as needed.

6. Finish and Serve
   Remove from heat, sprinkle with chopped cilantro, and serve directly from the skillet for a rustic, flavorful meal.

Avoid common mistakes:
– Don’t overcrowd the pan when searing steak—cook in batches for best browning.
– Slice steak thinly against the grain to keep it tender.
– Watch the garlic closely to prevent burning in the hot skillet.
