The Best Flank Steak Marinade

Flank Steak Marinade

Our mom told us about this marinade many years ago, and we have been making it ever since.  We searched high and low from where she found this recipe and finally found that we got it from Simply Recipes!  So thank you Simply Recipes for the best flank steak marinade ever!  Simply recipes says to grill it, but we provided a back up option for those of you that do not have a grill so that everyone can enjoy this flank steak!

Marinade Ingredients:

1/3 cup of Olive Oil

2 cloves of garlic, minced

2 tbsp. red wine vinegar

1/3 cup of soy sauce (or tamari for gluten free option)

1/4 cup of honey

1/2 tsp. freshly ground black pepper

Other Ingredients:

2 pounds of flank steak

kosher salt

freshly ground black pepper


 1 Score the surface of the steak with 1/4 inch deep knife cuts, about an inch apart, across the grain of the meat. Combine the marinade ingredients. Place steak and marinade ingredients in a large freezer bag. Coat the steak well with the marinade. Seal the bag and place in a bowl. Chill and marinate for at least 2 hours and up to overnight.


2 Using olive oil soaked onto a paper towel, coat the grill rack of your grill with olive oil. Preheat the grill with high, direct heat. The grill is hot enough when you hold your hand about an inch over it and you can only hold it there for about a second.

3 Take the steak out of the marinade bag and sprinkle generously on all sides with coarse salt and freshly ground pepper. The salt and pepper will help form a savory crust on the steak. Place steak on the hot grill. If you are using a gas grill, cover the grill. Grill for 4-6 minutes on each side. Half way through grilling on each side, turn the steak 90° so that you get more grill marks.

How do you know if the steak is done? The best way to tell is to poke it with your finger tips. While the steak is still raw, test it with your fingers; it will be quite squishy. That’s what a very rare steak feels like. As the steak cooks the muscles contract and firm up. Touch the tip of your nose and that’s what a very well done steak feels like. Here’s a visual guide, the finger test to check the doneness of steak.

4 Flank steak is best eaten medium rare; well done will make it too tough. When the steak has cooked to your preferred level of doneness, remove from the grill and place on a cutting board. Cover with aluminum foil to hold in the heat and to keep the steak from drying out, and let rest for 10 minutes.

5 Make very thin slices, against the grain, and at a slight diagonal so that the slices are wide.

If you want to oven bake it:  

Pre heat oven to 400 degrees.  In a large skillet over medium-high heat, heat pan until very hot.  Add about 2 tablespoons of olive oil.  Sear the flank steak for 2 minutes on each side.  Both sides should be well browned.  On a cooking tray wrapped in foil add flank steak. Place inside the oven and cook for an extra 5 minutes for medium rare or a little longer for medium.
