The cooking process explained
This dish is straightforward in its preparation, requiring only a few essential steps to achieve delicious results. Begin by preparing the marinade, which consists of key ingredients like balsamic vinegar, olive oil, garlic, and herbs. The flank steak should then be marinated for a sufficient period to allow flavors to penetrate, typically several hours or overnight. Cooking the steak to the desired doneness will yield a tender cut that can be sliced against the grain for serving.
Prep Time: 15 min | Cook Time: 10 min | Total Time: 25 min
What you’ll need
- Flank steak (about 1-1.5 pounds)
- 1/2 cup balsamic vinegar
- 1/4 cup olive oil (extra virgin if possible)
- 3 cloves garlic, minced
- 2 tablespoons fresh rosemary or thyme, chopped (or 1 tablespoon dried)
- Salt and pepper, to taste
Note: Using fresh herbs typically results in a brighter flavor compared to dried, although dried can be used as a convenient alternative.
Step-by-step instructions
- In a medium bowl, whisk together the balsamic vinegar, olive oil, minced garlic, herbs, salt, and pepper until well combined.
- Place the flank steak in a large resealable plastic bag or shallow dish and pour the marinade over the meat. Seal the bag or cover the dish, ensuring the steak is fully coated. Refrigerate for at least 2 hours, ideally overnight.
- Remove the flank steak from the refrigerator and allow it to come to room temperature for about 30 minutes before cooking.
- Preheat a grill or skillet over medium-high heat. Remove the steak from the marinade and discard the excess marinade.
- Cook the steak for about 4-5 minutes on each side for medium-rare, or longer according to your preferred level of doneness. Use a meat thermometer to check for an internal temperature of 130°F for medium-rare.
- Allow the steak to rest for at least 5 minutes before slicing against the grain.
Best ways to enjoy it
The sliced steak can be served simply on a platter, perhaps drizzled with a bit of the reserved marinade (that has been boiled to ensure safety) for added flavor. It pairs beautifully with roasted vegetables, a fresh salad, or creamy mashed potatoes. Incorporating seasonal vegetables or grains can elevate the dish further, ensuring a vibrant plate that balances the richness of the meat.
Storage and reheating tips
Leftover flank steak should be stored in an airtight container in the refrigerator, where it will remain fresh for up to 3 days. To reheat, it is best to slice the steak and warm it gently in a skillet over low heat, which helps to maintain tenderness. Avoid high heat to prevent the meat from becoming tough. Flank steak can also be successfully frozen for up to 3 months; however, it is best utilized fresh to appreciate its optimal texture and flavor.
Helpful cooking tips
For optimal flavor infusion, consider increasing the marinating time. While two hours can impart good flavor, overnight marination will yield a more deeply flavorful steak. Always slice flank steak against the grain; this technique shortens the tough muscle fibers and ensures every bite is tender. Additionally, checking the doneness with a meat thermometer will provide the most accurate results, particularly since overcooking can turn a normally tender cut into a chewy one.
Creative twists
Consider experimenting with different marinades to customize the flavor profile. Adding a splash of soy sauce or a spoonful of Dijon mustard to the balsamic marinade can introduce a delightful umami dimension. Alternatively, for a smoky flavor, try incorporating chipotle peppers or smoked paprika. Each variation brings a new interpretation to this dish while maintaining its fundamental ease of preparation.
FAQ
Can I use other cuts of meat instead of flank steak?
While flank steak is preferred for its flavor and tenderness, you can use other cuts such as skirt steak or sirloin. Each will have its own characteristics, with skirt steak being slightly more flavorful due to its fat content, while sirloin is leaner.
How do I achieve the perfect doneness?
The best way to determine steak doneness is to use a meat thermometer. For medium-rare, aim for an internal temperature of 130°F; for medium, 140°F; and for well-done, 160°F. Always allow the steak to rest after cooking, as this helps the juices redistribute.
What can I do with leftovers?
Leftover flank steak is excellent in salads, sandwiches, or stir-fries. Its flavor pairs well with various ingredients, such as roasted vegetables, fresh greens, or even in taco-style presentations, allowing for versatile meal prepping without feeling repetitive.
