What Kind of Balsamic Vinegar Should I Use?
For this Balsamic Flank Steak recipe, it’s best to use aged balsamic vinegar. Aged balsamic offers a deeper, more complex flavor with a hint of sweetness that beautifully complements the savory notes from the soy sauce and the richness of the steak. Its thicker consistency also helps it cling to the meat during marination, ensuring every bite is packed with flavor. If you only have regular balsamic vinegar on hand, it will work in a pinch; just keep in mind that you may want to reduce the marinade slightly to achieve a similar depth of flavor and texture.
Ingredients You’ll Need
Each ingredient in this dish plays an essential role in flavor and texture. Here’s what you’ll need:
- 1/2 cup balsamic vinegar (preferably aged): Provides a rich, tangy depth that enhances the meat’s natural flavors.
- 1/4 cup soy sauce (low sodium): Adds a savory umami kick while keeping the marinade balanced.
- 2 tablespoons honey (or brown sugar): Introduces a touch of sweetness that complements the acidity of the vinegar.
- 2 cloves garlic (minced): Infuses the marinade with aromatic warmth and complexity.
- 1 teaspoon black pepper (freshly ground): Offers a subtle heat that elevates the overall taste experience.
- 1 teaspoon olive oil (for marinating): Helps to coat the steak evenly, ensuring all flavors adhere beautifully.
- 1.5 pounds flank steak (trimmed of excess fat): Serves as the star of the dish, delivering a tender, juicy bite when grilled.
Step-by-Step: How to Make Balsamic Flank Steak

Whisk Together the Marinade
In a mixing bowl, combine 1/2 cup of balsamic vinegar, 1/4 cup of low sodium soy sauce, 2 tablespoons of honey (or brown sugar), 2 cloves of minced garlic, 1 teaspoon of freshly ground black pepper, and 1 teaspoon of olive oil. Whisk these ingredients together until they are well incorporated and the mixture is slightly thickened, creating a fragrant marinade that will enhance the steak’s flavor.
Marinate the Flank Steak
Place the trimmed flank steak in a resealable plastic bag and pour the prepared marinade over it. Seal the bag tightly, ensuring that the marinade fully coats the steak, then refrigerate for at least 2 hours—overnight is ideal for maximum flavor infusion. This step not only tenderizes the meat but allows it to absorb all those delicious flavors.
Preheat the Grill
Before grilling, preheat your grill to medium-high heat. This usually takes about 10-15 minutes and is crucial for achieving a good sear on your steak. The grill should be hot enough that when you place the steak on it, you hear a pronounced sizzle—that’s your cue for perfect browning.
Discard Marinade and Prepare to Grill
Take the flank steak out of the marinade and discard any remaining liquid to avoid flare-ups on the grill. Allowing excess marinade to drip off will help ensure a nice char without being overly wet on the grill surface. This also helps in achieving that beautifully caramelized crust.
Grill the Steak
Place the flank steak on the preheated grill and cook for about 5-7 minutes on each side. Aim for an internal temperature of 135°F for medium-rare doneness; you can use an instant-read thermometer to check this. Look for nice grill marks and a rich brown color as indicators that it’s time to flip.
Let It Rest
Once grilled to your desired doneness, remove the steak from the grill and allow it to rest for about 5 minutes. This resting period is essential as it allows juices to redistribute throughout the meat, ensuring every slice is juicy and tender when served.
Slice Against the Grain
After resting, slice the flank steak against the grain into thin strips. Cutting against the grain shortens muscle fibers, making each bite more tender and enjoyable. Serve immediately with your choice of sides or atop salads for a delightful meal!
How to Serve and Store Balsamic Flank Steak
This recipe makes four satisfying servings of balsamic flank steak, perfect for a family dinner or a gathering with friends. For a delightful meal, serve the steak sliced thin against the grain over a bed of creamy mashed potatoes or quinoa, allowing the juices to soak in and enhance each bite. A fresh arugula salad drizzled with a light vinaigrette can also complement the rich flavors beautifully while adding a refreshing crunch.
To store any leftovers, place them in an airtight container in the refrigerator, where they’ll stay fresh for up to three days. When reheating, add a splash of beef broth or water to keep the steak moist and tender; warm it on low heat to prevent drying out. While this dish does not freeze particularly well due to potential texture changes in the meat, enjoying it fresh will yield the best results.

Can I use a different cut of steak instead of flank steak? Yes, you can substitute flank steak with cuts like skirt steak or sirloin. Just keep in mind that cooking times may vary slightly, so be sure to check for the desired doneness.
Is this recipe gluten-free? This recipe is not gluten-free due to the soy sauce. However, you can easily substitute low-sodium tamari or a gluten-free soy sauce alternative to keep it gluten-free while still enjoying the dish.
Can I make the marinade ahead of time? Absolutely! You can prepare the marinade up to 3 days in advance and store it in the refrigerator. Just remember to give it a good stir before using it to ensure all ingredients are well combined.
How do I know when the steak is done cooking? The best way to check doneness is by using an instant-read thermometer; aim for an internal temperature of 135°F for medium-rare. If you prefer your steak more cooked, aim for 145°F for medium.
Can I add herbs or spices to the marinade for extra flavor? Yes, feel free to experiment by adding herbs like rosemary or thyme, or spices such as red pepper flakes if you’d like some heat. These additions can elevate the flavor profile and suit your personal taste preferences.
Can I cook this steak in the oven instead of on a grill? Yes, you can cook the steak in the oven if grilling isn’t an option. Preheat your oven broiler and place the marinated steak on a broiler pan, cooking for about 5-7 minutes on each side until it reaches your desired doneness.
