The beauty of this flank steak marinade lies in its simplicity and impact. A blend of acidic elements helps break down the muscle fibers, making the steak incredibly tender, while a mix of bold seasonings adds layers of flavor with every bite.

Letting the meat soak for at least a few hours – or better yet, overnight – ensures the marinade works its way deep into the steak, creating a rich, savory profile that grills up beautifully with a caramelized crust.

Flank steak is a lean and versatile cut that shines when treated right, and this marinade does just that. Once cooked to your preferred doneness and sliced thin against the grain, it’s ideal for tacos, steak salads, sandwiches, or served simply with your favorite sides.

This recipe is an easy go-to for anyone wanting to elevate their steak game with minimal effort and maximum flavor.

Ingredients to Gather

• Soy Sauce – Adds umami richness and saltiness that enhances the beefy flavor of the steak.
• Honey – Provides a touch of sweetness to balance acidity and helps create a caramelized crust when grilled.
• Red Wine Vinegar – Tenderizes the meat while adding a tangy depth that brightens the overall flavor.
• Garlic Powder – Brings warm, savory notes that complement the richness of the steak.
• Ground Ginger – Adds a subtle warmth and zing that pairs beautifully with the soy and honey.
• Avocado Oil – Helps the marinade coat the steak evenly and locks in moisture during cooking.
• Green Onion – Infuses the marinade with a mild, fresh bite and adds a layer of aromatic flavor.

I found this recipe in a cookbook published by the Charleston Junior League. Vintage cookbooks are the best! I changed the salad oil to avocado oil because it has a high smoke point.

Ingredients

1/4 cup soy sauce

3 tablespoons honey

2 tablespoons red wine vinegar

1 teaspoon garlic powder

1 teaspoon ground ginger

1/4 cup avocado oil

1 green onion, chopped

Directions

1. Whisk all the ingredients together until thoroughly combined.

How to Use Marinade for Flank Steak

Transfer the marinade to a resealable plastic bag and add the flank steak, making sure it’s fully coated. Squeeze out the excess air and seal the bag securely. Refrigerate for up to 8 hours to let the flavors soak in.

When you’re ready to cook, remove the steak from the bag and let any excess marinade drip off. Discard the remaining marinade, then grill or cook the steak to your desired doneness.

Tips

• Marinate for a long enough time – Let the steak marinate for at least 4 hours, but overnight is ideal for achieving deeper flavor and better tenderness.
• Score the meat – Lightly scoring the surface of the steak helps the marinade penetrate more effectively.
• Use a resealable bag – A zip-top bag ensures the marinade fully coats the steak and making cleanup easier.
• Don’t overdo acidic ingredients – Too much acid (like vinegar or citrus) for too long can break down the meat too much and make it mushy.
• Bring to room temp before cooking – Let the steak sit out for 20-30 minutes before grilling to promote even cooking.
• Always slice against the grain – Cutting the cooked steak thinly across the grain keeps it tender and easy to chew.
• Pat dry before cooking – Blotting off excess marinade helps get a nice sear instead of steaming the meat.
• Don’t reuse the marinade – Reusing the marinade is not a safe practice.
• This recipe is good for flank steak or London broil (2-3 pounds).

Grilling Tips

• Choose the Right Cut – Ribeye, strip, tenderloin, and sirloin are all great for grilling. Marbled cuts stay juicy and flavorful. 
• Let the Steak Come to Room Temp – Set your steak out 30-60 minutes before grilling so it cooks evenly. 
• Preheat the Grill – Get your grill hot. A screaming hot grill gives you that perfect crust. 
• Pat Steaks Dry – Moisture is the enemy of a good sear. Pat with paper towels before grilling. 
• Use the Two-Zone Method – Sear over high heat, then transfer to a cooler side to finish cooking to the desired temperature. 
• Don’t Flip Too Often – Flip once or twice. Let the crust develop. 
• Use a Meat Thermometer – Don’t guess. 
• Rest the Steak – Let it rest for 10 minutes after grilling so juices can redistribute. 
• Slice Against the Grain – For maximum tenderness.
