Flavorful Balsamic Flank Steak with Blue Cheese Crust

Balsamic Marinated Flank Steak with Blue Cheese Crust – Quick Dinner

This Balsamic Marinated Flank Steak with Blue Cheese Crust comes together in just over 30 minutes of active time and delivers a restaurant-quality dinner without the fuss. The tangy balsamic marinade tenderizes the steak while the broiled blue cheese crust adds a creamy, salty finish that feels incredibly indulgent.

I first made this on a busy Tuesday when I wanted something impressive but had almost no time to spare. The smell of balsamic hitting a hot pan still reminds me of that night.

Ingredients

• 1 ½ pounds flank steak
• ⅓ cup balsamic vinegar
• 2 tablespoons olive oil
• 2 cloves garlic, minced
• 1 teaspoon Dijon mustard
• ½ teaspoon salt
• ½ teaspoon black pepper
• ⅓ cup crumbled blue cheese (Roquerfort or Gorgonzola work well)
• 2 tablespoons breadcrumbs (panko preferred)
• 1 tablespoon fresh thyme leaves (or 1 teaspoon dried)
• Fresh parsley for garnish (optional)

Instructions

• In a small bowl, whisk balsamic vinegar, olive oil, minced garlic, Dijon mustard, salt, and pepper.
• Place flank steak in a shallow dish or zip-top bag and pour the balsamic marinade over it. Turn to coat evenly. Marinate at room temperature for 20 minutes or up to 2 hours in the fridge.
• Preheat your oven’s broiler to high and position a rack about 6 inches from the heat source. Line a baking sheet with foil.
• Remove steak from the marinade (discard leftover marinade) and place it on the prepared baking sheet. Pat the top dry with paper towels.
• In a small bowl, combine crumbled blue cheese, breadcrumbs, and fresh thyme. Press the mixture evenly onto the top of the steak.
• Broil the steak for 6 to 8 minutes for medium-rare, or until the blue cheese crust is golden and bubbling. (Check internal temperature: 135°F for medium-rare.)
• Remove from the oven and let the steak rest on a cutting board for 5 minutes. This keeps the juices inside.
• Slice the flank steak against the grain into thin strips. Garnish with fresh parsley if you like, and serve immediately.

Pro Tips

• For the best texture, slice flank steak against the grain, not with it. This makes every bite tender.
• Don’t skip the resting step. Cutting into the steak too early lets the juices run out and leaves it dry.
• If the blue cheese crust starts browning too fast, move the baking sheet to a lower rack or tent loosely with foil.
• Patting the steak dry before adding the crust helps the cheese mixture stick better and prevents sogginess.
• Use a sharp chef’s knife for slicing flank steak – a dull blade will tear the meat rather than cut it cleanly.

Variations

• Substitute blue cheese with crumbled feta or goat cheese for a milder flavor.
• Add a pinch of red pepper flakes to the balsamic marinade for a subtle kick.
• Top the steak with caramelized onions or roasted cherry tomatoes after broiling for extra sweetness.
• Serve the sliced steak over a bed of arugula with extra balsamic drizzle for a low-carb dinner.

Frequently Asked Questions

• Can I grill this instead of broiling? Yes. Grill over high heat for about 4 minutes per side, then add the blue cheese crust during the last minute of grilling.
• What if I don’t have breadcrumbs? Crushed crackers or almond flour work as a substitute in the crust mixture.
• How do I store leftovers? Store sliced steak in an airtight container in the fridge for up to 3 days. Reheat gently in a skillet to avoid overcooking.
• Can I make the marinade ahead of time? Absolutely. Mix the balsamic, oil, garlic, mustard, salt, and pepper up to 2 days in advance and keep it sealed in the fridge.
• What cut of steak can I use instead of flank? Skirt steak or sirloin flap steak work well, though cooking times may vary slightly.
• Is the blue cheese crust very strong? Baking mellows the flavor, so it becomes creamy and nutty rather than sharp. You can use a milder blue cheese if you prefer.
