Ingredients and Preparation

Ingredients

Here’s everything you’ll need to make steak fajitas for four people:

• 1 tablespoon unsalted butter
• 1 tablespoon oil (vegetable or olive oil work well)
• 1.5 pounds steak (flank, sirloin, or skirt), thinly sliced into ½ inch strips
• 2 teaspoons chili powder
• 1 teaspoon paprika
• 1 teaspoon onion powder
• 1 teaspoon garlic powder
• ½ teaspoon cayenne pepper (adjust to your heat preference)
• ½ teaspoon cumin powder
• 1 teaspoon cornstarch (helps the spices coat the meat evenly)
• Salt and black pepper to taste
• ½ cup red bell pepper, thinly sliced
• ½ cup green bell pepper, thinly sliced
• ½ cup onion, thinly sliced
• 1–2 teaspoons lemon or lime juice
• Optional garnish: chopped fresh cilantro

Ingredient Swaps and Suggestions

Steak Alternatives: While flank, sirloin, and skirt steaks are ideal for fajitas due to their tenderness and quick-cooking nature, you can also use chicken breast or thighs, or even portobello mushrooms for a vegetarian twist.

Butter/Oil Options: If you’re dairy-free, swap the butter for a bit more oil or use plant-based butter.

Vegetables: Bell peppers and onions are the classic combination, but feel free to throw in mushrooms, zucchini, or even shredded carrots for added texture and nutrients.

Spices: No chili powder? A mix of smoked paprika and a dash of cumin can still add plenty of flavor. Adjust the cayenne for more or less heat.

Step-by-Step Instructions

1. Prepare the Ingredients

Start by slicing your steak against the grain into thin ½ inch strips. This helps make the meat more tender. Slice your peppers and onions into thin, even strips so they cook at the same rate.

Measure out all your spices in advance—it makes the cooking process smoother and quicker.

2. Heat the Pan

Place a large nonstick skillet or sauté pan over medium-high heat. Add the butter and oil and let them heat until the butter melts and starts to bubble slightly. This combo helps develop a rich, flavorful base without burning the butter.

3. Cook the Steak

Add the sliced steak to the pan. Sprinkle the chili powder, paprika, onion powder, garlic powder, cayenne, cumin, cornstarch, salt, and pepper over the meat.

Use a wooden spoon or tongs to toss everything together, making sure the steak is coated evenly with the spices.

Cook for about 2 minutes, stirring occasionally, until the outside of the meat is no longer pink. The steak won’t be fully cooked through at this point, and that’s okay. It will finish cooking with the vegetables.

4. Add the Vegetables

Add the red and green bell peppers and the sliced onions to the pan. Continue sautéing everything together for another 5 to 6 minutes.

You’ll know it’s done when the vegetables are tender but still slightly crisp, and the steak is fully cooked and juicy.

5. Finish and Serve

Turn off the heat. Drizzle lemon or lime juice over the fajitas and toss everything together to coat evenly.

Taste and adjust the seasoning if needed—sometimes a little extra salt or citrus can elevate the dish even more.

Optional: Sprinkle with fresh cilantro for a burst of color and freshness.

Beginner Tips and Notes

Choosing the Right Cut of Meat

For fajitas, flank, skirt, or sirloin steak work best because they’re tender and cook quickly when sliced thinly. Always slice against the grain to ensure each bite is tender.

If the grain runs vertically, slice horizontally. This simple trick makes a huge difference in texture.

Don’t Overcrowd the Pan

If your pan is on the smaller side, cook the steak in batches. Overcrowding leads to steaming rather than searing, which can result in chewy meat.

Watch the Heat

Medium-high heat is perfect for browning the meat and softening the vegetables without burning them. If things start to brown too quickly, reduce the heat slightly or stir more often.

What If I Overcook the Veggies?

No worries—if your peppers end up too soft, just toss in a few fresh strips at the end for some crunch and color. Cooking is flexible. It’s all about balance and personal preference.

Substituting Kitchen Tools

No nonstick skillet? A cast iron pan works beautifully and can even enhance the sear on your steak.

No lemon or lime? A splash of vinegar (like white wine or apple cider) can mimic that bright acidity.

Serving Suggestions

Classic Serving Style

Serve your steak fajitas in warm flour or corn tortillas. If you have time, heat the tortillas briefly in a dry pan or wrap them in foil and warm them in the oven for a few minutes.

Top with:

• Sour cream or Greek yogurt
• Shredded cheese
• Sliced avocado or guacamole
• Salsa or hot sauce
• Fresh lettuce or chopped tomatoes

Healthy Options

For a low-carb version, serve the fajitas over a bed of greens or in lettuce cups. You can also pair it with quinoa, cauliflower rice, or black beans for a well-rounded meal.

Leftover Magic

Store leftovers in an airtight container in the fridge for up to 3 days. Reheat gently on the stove or in the microwave with a splash of water to prevent drying out.

Leftover steak fajitas also make great additions to:

• Rice bowls
• Omelets
• Quesadillas
• Tacos with a fried egg on top
