For the Marinade

1 1/2 pounds flank steak
1/2 Cup olive oil

1 teaspoon salt
1/4 teaspoon Tabasco Sauce
2 teaspoons Mexican oregano
2 teaspoons New Mexico red chile powder (or Ancho Chile Powder)
1 teaspoon garlic (minced)

How to Make Overnight Flank Steak Marinade

Step 1: Prepare the Marinade

In a small bowl, use a whisk to mix together all the marinade ingredients until they are well blended.

Step 2: Marinate the Steak

Place the flank steak into a gallon-sized zip lock bag.
Pour in the marinade mixture.
Seal the bag while pushing out as much air as possible.
Use your hands to squish the bag around several times to ensure that the beef is fully coated with the marinade.

Step 3: Refrigerate

Place the sealed bag in the refrigerator and let it marinate overnight. This allows the flavors to penetrate deeply into the meat.

Step 4: Preheat Grill

When you’re ready to cook, preheat your grill to about 600 degrees Fahrenheit. After reaching that temperature, lower the heat to medium or around 350 degrees.

Step 5: Grill the Steak

Remove flank steak from marinade and discard excess marinade. Grill for about 5-6 minutes on each side until desired doneness is achieved.

Step 6: Rest and Serve

Let the grilled steak rest for about 5 minutes tented with foil before slicing across the grain. Top with sliced green onions for presentation and serve immediately.
