🥩 Ingredients

Flank Steak | This cut of steak comes from the lower abdominal region of the cow that is great to grill, broil or use in sauté dishes. Always remember when cooking this cut to grill it over high heat and to cut against the grain when serving as there are long pieces of membrane running through.

Sazón | This is one of our favorite seasonings lately as it packs a huge burst of flavor using just a small amount. It is a seasoned salt that has cumin, cilantro and garlic in it that is found in a lot of Mexican and Latin dishes. When we use it, it always makes the dishes taste a bit more authentic. Look for it at most grocery stores in the hispanic aisle by the canned chiles and salsa.

Fajita Seasoning | Either use the Dizzy Pig version as shown, buy a substitute or make your own as you most likely have all of the ingredients in your pantry already.

Corn and Avocado Salsa | This is a traditional cool corn salsa. To ramp up the flavor, consider grilling the corn or boiling it in beer like we did for the Grilled Beer Corn and add it to the Black Bean and Corn Salsa, which is a great alternative to this version on top of the steak. Make a batch of this for the Grilled Chipotle Lime Chicken to serve on top or as a bed for the chicken.

🔥 Instructions

Flank Steak

This is an easy seasoning and marinade with lime juice and Corona beer.

Step One: Cut off all of the excess tissue and fat from the steak.

Step Two: Place slices of onion at the bottom of a baking dish. Combine the fajita seasoning and Sazón seasoning together and stir. Sprinkle a little on the onions, saving the vast majority of it for the steak itself.

Step Three: Rub the remaining seasoning on both sides of the steak and place on top of the onions. Pour the lime juice on top. Pour in the Corona beer and cover. Marinate in the refrigerator for 2-6 hours.

Step Four: Heat the grill up to 450 degrees on direct heat and grill the steak for 4-5 minutes for each side. You will want this to reach 130-135 for medium rare or 145 for medium. If you need to, make sure to use a wireless thermometer so you don’t over cook.

Allow it to rest under a tent of foil and then slice cross the grain and top with the Avocado Corn Salsa to serve.

Corn and Avocado Salsa

While the meat is marinating, start making the salsa.

Step One: Heat up the grill to medium high. Place three ears of corn in a dutch oven with water and boil for 10-15 minutes until tender. Once tender, remove the ears and place them on grill to sear for 3-5 minutes.

Tip: Take note that you will start your grilling day on medium high heat to make the corn. When it’s done, you can raise it up to the 450 degrees for the steak.

Step Two: Cut the corn off of the cob and add to a bowl. Add the remaining ingredients and gently stir.

Tip: Avocados are sensitive to air, so if you want to make these early, add them in right before you serve so they are still super fresh.
