Ingredients

Flank steak or skirt steak: This is classic for carne asada thanks to its rich beefy flavor and tender texture when sliced thin Select a cut that is evenly thick with good marbling for best results
Olive oil: Helps tenderize the meat and carries the marinade flavors Choose a good extra virgin olive oil for added richness
Fresh lime juice: Makes the marinade bright and zesty Always opt for juicy limes that feel heavy for their size
Garlic: Fresh cloves bring punch to the marinade and enhance the savoriness Mince just before using for most aroma
Ground cumin: Adds earthiness and warmth Reach for a freshly opened spice jar to keep the flavor vibrant
Smoked paprika: Gives a subtle smoky depth Use a Spanish variety for authenticity and check the date for freshness
Salt and pepper: Fundamental for seasoning both the meat and the entire dish Use kosher salt and fresh-cracked black pepper for best control
Corn tostada shells: Extra crunchy and sturdy to hold all the toppings Pick ones that feel crisp with no cracks or staleness
Guacamole: Creamy and cooling plus a great base for layering Ripe avocados are essential if making yourself
Sour cream or Mexican crema: Both add tang and creaminess Mexican crema is slightly thinner and richer Choose whichever you prefer
Diced tomatoes: Juicy and bright Select ripe but firm tomatoes to avoid sogginess
Fresh cilantro: Adds herbal lift and color Look for bunches of bright green soft leaves and avoid wilting
Sliced jalapeños: Offers spice for those who like heat Use fresh for crunch or pickled for a tangy bite
Lime wedges: Allows for last minute pops of brightness Give each wedge a squeeze so all the flavors really shine

Instructions

Marinate the Steak:: Combine olive oil lime juice minced garlic ground cumin smoked paprika salt and pepper in a bowl Whisk until well blended and fragrant Place steak in a sealable bag or shallow dish and pour the marinade over ensuring all sides are well coated Cover or seal and marinate in the refrigerator for at least one hour Overnight will yield the most flavorful results
Grill the Carne Asada:: Heat a grill or a large skillet over high heat until almost smoking Take steak out of the marinade letting excess drip away for proper searing Lay the steak on the hot surface and cook for five to seven minutes on each side Adjust the time depending on thickness and your preferred doneness The outside should get a nice char while the inside stays juicy Remove to a cutting board and let rest for several minutes for juices to settle Slice thinly against the grain to keep every piece tender
