Why Marinate Flank Steak?
Flank steak is cut from the abdominal muscles of the cow. It’s a tough but flavorful piece of meat, and it shines when it’s marinated and cooked properly. A good flank steak marinade:
- Adds flavor: Infuses the beef with bold, delicious notes—like soy sauce, garlic, citrus, and herbs.
- Tenderizes: Helps break down the muscle fibers so the steak is more tender and easier to chew.
- Juiciness: Keeps the steak moist during cooking, especially on a hot grill or pan.
Best Flank Steak Marinade Recipe (Quick & Easy)
Here’s a go-to marinade that works for grilling, broiling, or stovetop cooking. It’s the perfect blend of savory, sweet, and tangy—ideal for soaking into flank steak.
Ingredients:
- 1/4 cup soy sauce
- 1/4 cup olive oil
- 2 tablespoons balsamic vinegar
- 2 tablespoons Worcestershire sauce
- 2 tablespoons honey (or brown sugar)
- 3 cloves garlic, minced
- 1 tablespoon Dijon mustard
- 1 teaspoon black pepper
- 1/2 teaspoon red pepper flakes (optional)

Instructions:

- Marinate the steak: Place the flank steak in a large resealable bag or shallow dish. Pour the marinade over it. Seal and refrigerate for at least 2 hours—but 8 to 24 hours is ideal.

Pro Tips for Marinating Flank Steak
To get the most out of your flank steak marinade, follow these simple tips:
1. Use Acid Wisely
Acidic ingredients like vinegar or citrus juice help tenderize, but too much can make the meat mushy. Balance with oil and sweeteners.
2. Marinate Long Enough
Flank steak is dense. Aim for at least 8 hours if you can. Overnight is even better.
3. Don’t Reuse Marinade
If you want to use the marinade as a sauce later, boil it first to kill any bacteria from the raw meat.
4. Pat Dry Before Cooking
Removing excess marinade ensures a good sear and avoids steaming the steak.
