Tenderizing Flank Steak Marinade
This herby, umami-loaded flank steak marinade adds savoriness while tenderizing an intensely flavorful but challenging steak. Add more zing to your fajitas, tacos, and salad bowls, whether using the grill, smoker, or that cast-iron skillet for a great pan-sear.

I love flank steak because it’s an economical and beefy cut. Besides, cooking it hot and fast delivers a quick and easy weeknight meal.
However, a good marinade is the secret to juicy, tender beef. Let it soak in all that flavor, sear it, then slice it thinly to enjoy right then, or store it in the fridge for easy lunch prep.

Why Marinating Works for Flank Steak
This particular cut of beef is a hardworking muscle that runs on the tough side, but that also means it has more flavor. The acidity from the vinegar tenderizes it for a juicy steak you can cook hot and fast for a quick entree. Plus, you can start it marinating in the morning and have it ready to go when you get home for dinner.

How to Make Flank Steak Marinade

- So easy!!! Mix all the ingredients, done.

- Add the flank steak, and let it marinate for an hour or more. However, you want to avoid overmarinating flank steak (not more than 24 hours) so you don’t end up with mushy meat.
- Put your flank steak in the smoker or on the grill until done, then let it rest for 8-10 minutes, slice thinly against the grain, and enjoy in fajitas, tacos, etc.
Recipe Notes
- Swap the balsamic vinegar with lime or lemon juice or other flavors of vinegar for the acidity.
- When you’re ready to grill, drain the excess marinade and pat the steak dry. Excess moisture can interfere with the searing, and steam your meat instead.
- If you want to use the leftover marinade for a sauce, simmer it to reduce it and kill unwanted bacteria.

Make-Ahead and Storage Instructions
The marinade will stay good in a glass jar for a day or two. And you can marinate your steak overnight (8-12 hours) to cook the next day.
Slice flank steak thinly across the grain and store leftovers in an airtight container for up to 4 days. Top salads and diversity bowls for a quick and healthy lunch.
