Beef Steak Fajitas: Mexican Sizzling Strips
These beef steak fajitas are a savoury Mexican staple featuring tender strips of halal beef, sliced red and green bell peppers, and onions. You wrap the seared meat and softened vegetables in warm flour tortillas. This dinner provides a balance of protein and fibre with a bright finish from fresh lime juice and optional toppings like avocado and pico de gallo.
You must remove the steak from the fridge two minutes before cooking to ensure even searing. Once seared to an internal temperature of 63°C (145°F), let the meat rest for 5 minutes to redistribute the juices and keep the beef moist. Slice the rested steak against the grain to ensure the meat is tender rather than chewy. Failing to slice against the grain results in a tougher texture that resists the bite.

Recipe cardIngredients
Instructions
-
Prepare the marinade
Whisk the olive oil, lime juice, minced garlic, cumin, smoked paprika, salt and black pepper in a medium bowl. Mix until the spices are fully integrated. This ensures every piece of meat receives an equal distribution of flavour.
-
Marinate the beef
Place the steak in a zip-top bag or shallow container and pour the marinade over it. Seal the container and refrigerate for 15 minutes. This short soak tenderises the beef fibres.
-
Temper the meat
Remove the steak from the fridge 2 minutes before you intend to cook. Allow the meat to come to room temperature. You do this to achieve an even sear across the entire surface of the steak.
-
Sear the steak
Heat a heavy-bottomed skillet over high heat until a drop of water evaporates instantly. Sear the steak for 3 minutes on each side for medium-rare. Aim for an internal temperature of 63°C (145°F).
-
Rest the beef
Transfer the steak to a cutting board and cover it loosely with foil. Let it rest for 5 minutes. This allows the juices to redistribute so the meat stays moist when you slice it.
-
Cook the vegetables
Add 15 ml of olive oil to the hot skillet. Add the sliced onions and bell peppers, stirring occasionally for 3 to 4 minutes. Cook until they are softened and lightly charred for a smoky taste.
-
Slice and assemble
Thinly slice the rested steak against the grain into bite-sized strips. Warm your tortillas for 30 seconds per side in a skillet or 15 seconds in a microwave wrapped in damp cloth. Fill the tortillas with beef and vegetables.
Ensure you slice the steak against the grain. If you cut with the grain, the meat will feel chewy and tough. Look for the direction of the muscle fibres and cut perpendicularly across them to improve tenderness.
What to serve with it
Pair your beef steak fajitas with homemade guacamole and fresh pico de gallo for extra crunch. A spicy corn and black-bean salad adds a traditional Mexican side. Finish the meal with a squeeze of fresh lime over the hot tortillas to add a burst of citrus to the savoury meat.
Storing and reheating
Keep leftovers in a shallow sealed container for up to 2 hours at room temperature before refrigerating. You can freeze the cooked beef and vegetables in airtight bags for up to 3 months. Thaw the food overnight in the fridge before reheating to maintain the meat texture.

Questions people ask
What kind of steak is best for steak fajitas?
Use skirt or rump steak for this recipe. These cuts provide the right balance of flavour and texture. They sear quickly at high heat and remain tender when sliced thinly against the grain.
What is the secret to making beef fajitas tender?
Slice the rested steak against the grain. This cuts through the tough muscle fibres. Let the meat rest for 5 minutes after searing to ensure the juices redistribute, which prevents the meat from becoming dry.
Do I need to marinate steak for fajitas?
Yes. Marinating for at least 15 minutes allows the lime juice and spices to penetrate the meat. The acidity in the lime juice helps break down the protein, ensuring the beef is tender and seasoned.
