🔥 How To Make Spicy Steak Fajitas
Step 1 – Marinate the Steak
Place the sliced sirloin steak into a large zip-lock bag. Add the lime juice, chili powder, cayenne pepper, minced garlic,
and 1 tablespoon of olive oil. Seal the bag tightly and shake well to ensure every piece of steak is coated in the spicy marinade.
Let it sit for at least 20 minutes or up to 8 hours in the refrigerator for maximum flavor.
Step 2 – Add the Vegetables
Add the sliced red, yellow, and green bell peppers, along with the sliced onion, to the same bag. Seal it again and shake
to distribute the seasoning and oil evenly over the vegetables.
Step 3 – Sauté Everything
Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Once hot, pour all the contents from the bag
(steak, spices, vegetables, everything!) into the skillet. Cook while stirring occasionally until:
- The vegetables become slightly tender but still crisp.
- The steak is cooked through and lightly browned.
This usually takes about 8–12 minutes, depending on your stove and how thinly the steak is sliced.
Step 4 – Serve With Style
Warm the tortillas in a dry skillet or microwave. Add a generous scoop of steak and veggies to each tortilla, sprinkle with
shredded Mexican cheese, and add your favorite toppings:
- Sour cream
- Guacamole
- Pico de gallo
- Hot sauce
- Cilantro
- Extra lime juice
✨ Tips for Perfect Fajitas
- Cut steak thinly across the grain for tenderness.
- Don’t overcook – sirloin becomes chewy if cooked too long.
- Cast-iron skillet = best flavor thanks to high heat.
- Add extra cayenne or jalapeños for more heat.
- Swap steak for chicken or shrimp for variation.
