Balsamic Marinated Flank Steak with Blue Cheese Crust

🍽️ Description

This dish combines the bold, tangy sweetness of a balsamic marinade with the rich, savory depth of a crusted blue cheese topping. The flank steak is first tenderized and infused with a reduced balsamic-based marinade, then grilled or pan-seared to perfection and finished under a broiler with a melted blue cheese crust. The result is a restaurant-style steak that balances acidity, umami, and creamy sharpness in every bite.

🛒 Ingredients

For the steak:

  • 1.5–2 lbs flank steak
  • ½ cup balsamic vinegar
  • ¼ cup olive oil
  • 3 cloves garlic, minced
  • 1 tbsp Dijon mustard
  • 1 tbsp honey
  • 1 tsp salt
  • ½ tsp black pepper
  • 1 tsp dried rosemary (or thyme)

For the blue cheese crust:

  • ¾ cup crumbled blue cheese
  • 2 tbsp mayonnaise or cream cheese
  • 1 tbsp Dijon mustard
  • 1 tbsp chopped parsley (optional)

🔪 Instructions

1. Marinate the steak

  • Whisk balsamic vinegar, olive oil, garlic, mustard, honey, salt, pepper, and herbs.
  • Place flank steak in a resealable bag or dish.
  • Pour marinade over steak and refrigerate for at least 2–8 hours (overnight preferred).

2. Cook the steak

  • Remove steak from marinade and let it come to room temperature.
  • Grill or pan-sear over high heat for 4–6 minutes per side (medium-rare preferred).
  • Rest steak for 10 minutes before topping.

3. Prepare the crust

  • Mix blue cheese, mayonnaise/cream cheese, mustard, and parsley until spreadable.

4. Finish under broiler

  • Spread blue cheese mixture evenly over rested steak.
  • Broil for 2–4 minutes until melted, bubbling, and lightly golden.

5. Slice & serve

  • Slice against the grain for maximum tenderness.

📝 Recipe Notes

  • Flank steak must be sliced against the grain to avoid chewiness.
  • Marinating time significantly affects tenderness—don’t rush it.
  • Blue cheese intensity varies; choose mild or strong based on preference.
  • You can substitute skirt steak if flank is unavailable.

💡 Tips for Best Results

  • Pat steak dry before searing for a better crust.
  • Use high heat for searing to lock in juices.
  • Let steak rest before slicing to prevent juice loss.
  • If grilling, oil the grates to avoid sticking.
  • Add a splash of balsamic reduction on plating for extra flavor boost.

❓ Q&A

Q: Can I make this without blue cheese?

Yes. You can substitute with feta, goat cheese, or a garlic herb butter for a milder flavor.

Q: What’s the best doneness for flank steak?

Medium-rare to medium (130–140°F / 54–60°C) is ideal for tenderness.

Q: Can I grill instead of broiling?

Yes. After grilling, place steak on indirect heat and melt the cheese topping with the lid closed.

Q: How long should I marinate the steak?

Minimum 2 hours, but 8–12 hours gives the best flavor penetration.

Q: Can I meal prep this?

You can marinate ahead, but cook and add cheese crust fresh for best texture.
