Key Ingredients for Flank Steak Tacos

See recipe card below for full list of measurements, ingredients, and instructions.

Flank Steak

Flank steak is the star of this recipe, offering deep beefy flavor and tenderness when sliced thin across the grain. Choose a well-marbled cut for maximum juiciness. Let it come to room temperature before grilling for even cooking. If you can't find flank steak, skirt steak or flat iron steak are great alternatives-just as flavorful with a similar texture.

Fresh Lime Juice

Lime juice brings a bright acidity to the marinade, tenderizing the meat and adding a zesty kick. Always use freshly squeezed lime for the best flavor. Lemon juice can work in a pinch, but it slightly changes the flavor profile.

Garlic

Minced garlic infuses the steak with aromatic depth and a subtle sharpness. Fresh garlic is best for maximum impact. If you're short on time, a teaspoon of garlic powder can be used instead.

Smoked Paprika

This spice gives the marinade a wonderful smoky undertone without the need for a smoker. Regular paprika works, too, but go for smoked if you want that authentic street taco flavor. A pinch of chipotle powder can bring an extra layer of heat and smoke if you crave it spicy!

Corn Tortillas

Corn tortillas provide an earthy, slightly sweet base for your tacos and are naturally gluten-free. Warm them on the grill until lightly charred for the best taste and texture. Prefer flour tortillas? No problem-they'll work just as well and are perfect if you want a softer taco.

Instructions for Flank Steak Tacos

See recipe card below for full list of measurements, ingredients, and instructions.

Marinate the Steak

In a large bowl or zip-top bag, combine olive oil, lime juice, garlic, smoked paprika, cumin, chili powder, salt, and pepper. Add the flank steak and turn to coat evenly. Let it marinate for at least 15 minutes (or up to 2 hours in the fridge for more flavor). While it marinates, prep your taco toppings.

Preheat Your Grill

Heat an outdoor grill or cast iron grill pan over medium-high until very hot. Lightly oil the grates to keep the steak from sticking-you want that perfect grill mark action!

Grill the Flank Steak

Remove steak from the marinade and let excess drip off. Grill for 4-5 minutes per side for medium-rare, or until the internal temperature reaches 130-135°F. Adjust cook time according to your preferred doneness. Let the steak rest for at least 5 minutes-this keeps it super juicy.

Warm the Tortillas

While the steak rests, grill or dry-toast the tortillas for about 30 seconds per side, just until soft and a bit charred. Keep them wrapped in a clean towel to stay warm.

Slice the Steak and Assemble

Slice the steak thinly against the grain. Pile juicy steak slices into each warm tortilla, then top with diced red onion, cilantro, queso fresco, avocado, and a spoonful of pico de gallo. Add a squeeze of fresh lime juice for extra zing!

Recipe Variations

Spice It Up

For extra heat, add a diced jalapeño or a pinch of cayenne pepper into the marinade. Want a smoky, spicy flavor? Stir in some chipotle in adobo sauce before grilling.

Citrusy Marinade Twist

Switch out lime juice for orange juice for a slightly sweeter, more mellow marinade. It adds beautiful caramelization and a subtle tropical flair.

Veggie Tacos

Swap flank steak for portobello mushrooms or sliced zucchini. Marinate and grill the same way for a fantastic vegetarian version that still captures those smoky, bold flavors.

Dairy-Free & Gluten-Free

Skip the queso fresco for completely dairy-free tacos. If you use corn tortillas, this meal is naturally gluten-free-just check packaging to confirm.

Serve Bowl Style

Try a taco bowl instead! Layer steak, toppings, and a base of rice or shredded lettuce for a fun, low-carb twist.

Serving Suggestions

Serve your Flank Steak Tacos with smoky black beans, Mexican rice, or a tangy cabbage slaw to round out the meal. Top with fresh cilantro, avocado, and a squeeze of lime juice for a burst of flavor. A side of tortilla chips and your favorite salsa or creamy guacamole turns these tacos into a true fiesta spread!

Storage and Reheating

Store leftover steak and toppings separately in airtight containers in the refrigerator for up to 3 days. To reheat steak, warm slices in a skillet over medium-low heat just until heated through, or microwave in short bursts to avoid overcooking. Tortillas are best warmed fresh, but can be wrapped in a damp paper towel and microwaved for 20 seconds. Freeze cooked steak (tightly wrapped) for up to 2 months-thaw in the fridge overnight before reheating.
