  • 1/4 tsp. rosemary

Tips & Substitutions

For best results, use a high-quality flank steak. If you prefer a stronger garlic flavor, opt for 1/2 tsp. instead of 1/4. You can substitute the wine vinegar with apple cider vinegar for a slightly different taste. Consider marinating for up to 24 hours for deeper flavor infusion. Make sure to slice the steak against the grain to ensure tenderness, which is essential for achieving the best texture.

Serving Suggestions

Serve the marinated flank steak with a side of grilled vegetables or a fresh salad for a balanced meal. It pairs beautifully with a tangy chimichurri sauce or even the refreshing flavors of a Pineapple Mint Jelly. For a complete dinner, consider serving it alongside garlic mashed potatoes or a light couscous salad for added texture and flavor.

Storage & Reheating

Store any leftover marinated flank steak in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm it in a skillet over low heat to maintain tenderness, or slice it cold for salads. If you prefer to freeze, wrap it tightly in plastic wrap followed by aluminum foil, and it will last for up to 3 months.

Frequently Asked Questions

Can I use other cuts of meat for this recipe?

Yes, while flank steak is ideal for marinating, you can substitute it with skirt steak or sirloin. Each will provide a slightly different texture and flavor. Just ensure that any cut you choose is marinated adequately to enhance tenderness and flavor.

How long should I marinate the flank steak?

Marinating the flank steak for at least 8 hours is recommended, but for optimal flavor, you can marinate it overnight up to 24 hours. This allows the flavors to penetrate the meat more thoroughly, resulting in a juicier and more flavorful dish.

What should I serve with marinated flank steak?

Marinated flank steak pairs well with a variety of sides such as grilled asparagus, roasted potatoes, or a quinoa salad. For a refreshing drink, try a Patio Cooler, which complements the savory flavors of the steak beautifully.
