Skillet Steak Fajitas Recipe: Quick Sizzled Steak & Peppers

These steak fajitas use a simple homemade spice blend, crisp bell peppers, and thinly sliced sirloin steak for a flavorful, family-friendly meal.

Serve with warm tortillas and your favorite toppings: guacamole, sour cream, shredded cheese, and lime wedges.

These skillet steak fajitas come together quickly and are cooked in a single pan for easy preparation and fast cleanup. They’re perfect for weeknights yet tasty enough for guests.

Homemade Seasoning

The recipe relies on a homemade fajita seasoning that evenly seasons the steak and adds bright, smoky flavor. The mix combines chili powder, cumin, oregano, paprika, garlic powder, and onion powder.

This amount is enough for the recipe, but you can double or triple the batch and keep extra seasoning on hand for tacos, grilled vegetables, or other Mexican-style dishes.

Skillet Steak Fajitas

A cast iron skillet is ideal for these fajitas because it holds heat and builds a nice sear on the steak, but any heavy skillet will work. If you like the restaurant presentation, serve the fajitas in a sizzling skillet.

To cook: melt butter in the skillet over medium heat, add the steak, and sear it on both sides. Sprinkle the fajita seasoning over one side, flip the steak, and season the other side so the flavor is balanced.

After the steak is browned, remove it briefly to slice against the grain into thin strips — slicing against the grain keeps the meat tender. Return the sliced steak to the skillet, add the sliced peppers and onions, and cook for about five minutes until the vegetables are softened but still vibrant.

Finish with a drizzle of lime (or lemon) juice, toss to combine, and serve immediately with warm tortillas.

Garnishes and Toppings

A squeeze of lime brightens the flavors and brings out the spices. Add shredded cheese—mild cheddar or a Mexican blend—along with sour cream or fresh guacamole for creaminess. Sliced avocado is another simple, delicious option.
