How to Make Balsamic Flank Steak
-
Combine Ingredients: In a large plastic bag or shallow dish, mix together dijon mustard, minced garlic, onion powder, soy sauce, olive oil, and balsamic vinegar. Season the steak on both sides with salt and pepper, then add it to the marinade. Seal and let it enjoy the flavors for at least 2 hours, or better yet, overnight in the refrigerator.
-
Prepare the Grill: When it s time to cook, brush grill grates with oil and preheat your outdoor grill to high heat (450 °F). Take the flank steak out of the marinade, letting any excess drip off, but keep that marinade for later!
-
Grill the Steak: Place the flank steak on the hot grill and close the lid. Cook for about 3-5 minutes on each side for juicy medium-rare, aiming for an internal temperature of 135 °F.
-
Add Zucchini to the Grill: While flipping the steak, brush the thick zucchini slices with olive oil and sprinkle them lightly with salt. Lay them on the grill and cook for 2-3 minutes on each side until they become tender and have nice grill marks.
-
Rest the Steak and Zucchini: Once grilled, transfer the steak and zucchini to a clean cutting board and allow them to rest for about 10 minutes. This is key for juicy meat!
-
Make the Balsamic Glaze: While the steak is resting, take the reserved marinade and pour it into a medium saucepan. Bring it to a rolling boil over medium-high heat, then reduce to a simmer and let it thicken for about 2-3 minutes. This will create a delicious glaze to drizzle over your dish.
-
Blend the Whipped Feta: Grab a blender or food processor, add the feta and the heavy cream, and blend until you achieve a smooth, creamy texture.
-
Brush with Glaze: Once rested, brush half of the balsamic glaze on the sliced flank steak and cut it thinly against the grain for tender bites.
-
Plate and Serve: On each plate, spoon a generous layer of whipped feta, place the grilled steak and zucchini on top, and finish with a drizzle of the remaining balsamic glaze. Enjoy your delicious creation!
Optional: Garnish with fresh herbs like parsley for an extra pop of color.

How do I choose the best flank steak?

Can I freeze the Balsamic Flank Steak?
Absolutely! To freeze your Balsamic Flank Steak, first allow it to cool completely. Then wrap the steak tightly in plastic wrap and then in aluminum foil or place it into a heavy-duty freezer bag.

What if my steak is tough after grilling?
Don’t worry; it happens! If you find your Balsamic Flank Steak to be tough, check that you sliced it against the grain; this makes a huge difference in tenderness. Additionally, marinating the steak longer next time, or even using a meat tenderizer before grilling, can help achieve that melt-in-your-mouth quality.
Are there any allergies to consider with this recipe?

How ripe should the zucchini be before grilling?

Aim to use zucchini that s about 6-8 inches long for the best results in your Balsamic Flank Steak with Zucchini and Whipped Feta!
