The Science Behind the Perfect Flank Steak
Why Flank Steak?
Flank steak is a flavorful, lean cut that benefits from:
- Quick cooking (ideal for weeknights)
- Absorbing marinades beautifully
- Slicing against the grain for tenderness
How Balsamic Vinegar Works in the Marinade
- Acidity helps break down tough muscle fibers
- Natural sugars caramelize for perfect searing
- Depth of flavor balances the meat’s richness
Ingredient Breakdown: Quality Matters
For the Steak & Marinade
- 1.5 lb flank steak (look for even thickness)
- ⅓ cup balsamic vinegar (aged for best flavor)
- 3 tbsp olive oil (extra virgin recommended)
- 1 tbsp Dijon mustard
- 1 tsp honey
- 2 garlic cloves, minced
- 1 tsp fresh thyme leaves (or ½ tsp dried)
- ½ tsp red pepper flakes (optional)
- 1 tsp kosher salt
- ½ tsp black pepper
For the Zucchini
- 2 medium zucchini, sliced ½-inch thick
- 2 tbsp olive oil
- ½ tsp garlic powder
- Salt and pepper to taste
For the Whipped Feta
- 6 oz feta cheese, crumbled
- 3 oz cream cheese, softened
- 2 tbsp Greek yogurt
- 1 tbsp lemon juice
- 1 tbsp olive oil
- ½ tsp black pepper
Step-by-Step Cooking Instructions
1. Marinate the Steak (20 minutes – 2 hours)
- Whisk together all marinade ingredients in a bowl.
- Place steak in a shallow dish or ziplock bag, pour marinade over.
- Massage marinade into meat, ensuring full coverage.
- Marinate at room temp for 20 minutes, or refrigerate up to 2 hours.
Pro Tip: Never marinate flank steak more than 4 hours – the acidity can make it mushy.
2. Prepare the Whipped Feta
- Combine all ingredients in a food processor.
- Blend until completely smooth (about 2 minutes).

3. Cook the Zucchini
- Preheat oven to 425°F (220°C).
- Toss zucchini slices with oil and seasonings.
- Arrange in single layer on baking sheet.
- Roast 12-15 minutes until golden and tender.
4. Cook the Steak to Perfection
- Heat grill or heavy skillet to high heat (about 450°F).
- Remove steak from marinade (pat dry for better sear).
- Cook 4-5 minutes per side for medium-rare (130°F internal temp).
- Transfer to cutting board, tent with foil, rest 10 minutes.
Doneness Guide:
- Rare: 120°F (3-4 mins per side)
- Medium-rare: 130°F (4-5 mins)
- Medium: 140°F (5-6 mins)
5. Slice and Serve
