How to Make Balsamic Flank Steak

Step 1: Prepare the Marinade

1. In a large plastic bag or shallow dish, combine the Dijon mustard, minced garlic, onion powder, soy sauce, olive oil, and balsamic vinegar.
2. Season both sides of the flank steak with salt and black pepper.
3. Place the steak into the marinade, ensuring it is fully coated. Seal the bag or cover the dish and refrigerate for at least 2 hours or overnight.

Step 2: Preheat the Grill

1. Brush grill grates with oil.
2. Preheat your outdoor grill to high heat (450°F).

Step 3: Cook the Steak

1. Remove the flank steak from the marinade, shaking off excess but reserving the marinade for later.
2. Place the steak on the hot grill, close the lid, and cook for about 3–5 minutes on each side until medium-rare (aim for an internal temperature of 135°F).

Step 4: Grill the Zucchini

1. While grilling the steak, brush sliced zucchini with olive oil and sprinkle with kosher salt.
2. Add zucchini to one side of the grill when flipping the flank steak. Grill for about 2–3 minutes on each side until tender and charred.

2. Allow them to rest on a cutting board for about 10 minutes.

Step 6: Make Balsamic Glaze

Common Mistakes to Avoid

Cooking balsamic flank steak can be simple, but there are some common mistakes to keep in mind to ensure your dish turns out perfectly.

• Not marinating long enough: Marinating the steak for at least 2 hours or overnight enhances the flavor. Shortening this time can result in a less tasty dish.
• Skipping the resting period: Allowing the steak to rest after grilling is crucial. This helps the juices redistribute, ensuring a juicy and tender bite.
• Ignoring cooking temperature: Using a meat thermometer is essential for achieving the desired doneness. Cooking without checking can lead to overcooked or undercooked steak.
• Overcrowding the grill: Placing too many items on the grill at once can lower the temperature and cause uneven cooking. Grill in batches for better results.
• Not using enough salt: Seasoning both sides of the steak with salt before marinating is vital. It brings out the flavors in the meat and enhances overall taste.
