How to Make Beef Steak Fajitas
1. Marinate the beef
Place the steak and all marinade ingredients into a zip-top bag or bowl. Massage the marinade into the meat and refrigerate for at least 2 hours or up to overnight.
2. Prepare the steak
Remove the steak from the refrigerator 30 minutes before cooking so it can come to room temperature. Pat it dry with paper towels and lightly brush with oil.
3. Cook the steak
Heat a grill or skillet over high heat. Cook the steak for about 1–2 minutes per side, depending on thickness and desired doneness.
Transfer the steak to a plate, cover loosely with foil, and let it rest.
4. Cook the vegetables
In the same skillet, heat a little oil and cook the sliced onions until soft and slightly charred. Remove and set aside.
Add the sliced bell peppers and cook until tender and lightly charred.
5. Slice the beef
Slice the steak thinly against the grain. Cutting across the muscle fibers makes the meat much more tender.
6. Assemble the fajitas
Warm the tortillas and fill them with steak, peppers, onions, and your favorite toppings.
Serve with avocado, cilantro, sour cream, and lime wedges.
Tips for the Best Fajitas
Use the right cut of steak
Skirt steak or rump steak works best because the marinade helps tenderize them.
Cook on very high heat
A hot pan or grill creates a flavorful sear.
Don’t overcook the steak
Medium-rare or medium keeps the beef juicy.
Slice against the grain
This ensures tender, easy-to-eat slices.
Quick Version (No Marinating)
If you’re short on time, you can skip the marinade and use a quick spice rub instead:
- ½ tsp chipotle powder
- ¼ tsp garlic powder
- ⅛ tsp smoked paprika
- ⅛ tsp cumin
- ⅛ tsp coriander
- ¼ tsp dried oregano
- ¼ tsp salt
- Black pepper
Rub onto the steak and let sit for 5–10 minutes before cooking.
