Smoky, spicy, and topped with roasted red pepper and onion, these Flank Steak Tacos are the perfect meal to please the whole family.
Nothing beats a freshly grilled taco when the weather warms up. If the word taco conjures an image of flour tortillas filled with ground beef, cheddar cheese, and iceberg lettuce, then you are in for a real treat. My quick and easy spice rub is full of flavor and takes minutes to prepare, creating flavor packed Flank Steak Tacos. Not the right weather for grilling? No worries, you can make these in the oven, too!
- For the dry rub: cumin, smoked paprika, oregano, garlic powder, coriander, kosher salt, black pepper, cayenne pepper.
- For the tacos: flank steak, onion, red pepper, corn tortillas, toppings of choice.
How to Make Flank Steak Tacos
Start your flank steak tacos by creating your spice rub.
In a dish large enough to fit most of the steak, add the cumin, smoked paprika, oregano, garlic powder, coriander, cayenne pepper, kosher salt, and pepper.
Mix all of the spices together to make your dry rub, and get your grill or broiler heating up to medium-high heat.
Then you’ll make sure to coat your steak evenly on both sides, let it marinate for at least 30 minutes, then throw it on the grill for about 4 minutes a side for medium-rare, or until you’ve reached desired doneness.
Next, take your sliced onion and red pepper and drizzle them with olive oil. Season with salt and pepper, then wrap up in a tin foil boat. Toss them on the grill in the tin foil for about 10 minutes.
Once you remove the steak from the grill or oven, let it rest for a few minutes, then slice it into thin strips.
Remove the veggies and they’ll be slightly caramelized and delicious. You can toss your tortillas on the grill for about a minute as well to warm them up, or warm them on the stove.
You’re ready to assemble your tacos! Take the warmed tortillas, and layer steak, grilled veggies, and any toppings of choice.
Finish them off with a squeeze of fresh lime juice and cilantro, and enjoy your Flank Steak Tacos!
Change It Up
- Change the protein. You could also use skirt or flat iron steak. Not a fan of red meat? Use this rub on chicken breasts or thighs.
- Add some toppings. Toss together some pico de gallo or salsa; mash up some avocados to make some guacamole. Like it spicy? Add some sliced jalapeño.
Frequently Asked Questions:
How do I cut flank steak for tacos?
Cut it against the grain into thin strips. To see which way the grain is going, look at the whole steak and see which direction the muscle fibers are going.
Is flank steak or skirt steak better for tacos?
Both can be used for tacos, but flank steak is the more lean, less chewy option.
What is broiling?
Broiling is basically indoor grilling. Set your oven on broil (usually has 2 settings, low or high), and it applies direct heat from just the top of the oven. So just like flipping the meat on the grill half-way through, you’ll want to flip your food half-way through broiling as well.
How do I store leftover flank steak tacos?
Keep the ingredient separate in their own air-tight containers, and leftovers will keep in the fridge for up to 3 days.
