Coffee and Soy Marinated Flank Steak, Made Easy

Step 1: Prepare the Marinade
Start by gathering all the marinade ingredients. In a mixing bowl, combine the minced garlic, finely chopped onion, strong coffee, soy sauce, pepper, brown sugar, olive oil, rice vinegar, and Worcestershire sauce. Use a whisk to blend everything together until the brown sugar dissolves and the marinade is smooth.
Step 2: Marinate the Steak
Place the flank steak in a resealable plastic bag or a shallow dish. Pour the marinade over the steak, ensuring it is well-coated. Seal the bag or cover the dish, then refrigerate for at least 2 hours, or ideally overnight. This allows the flavors to penetrate the meat, making it tender and flavorful.
Step 3: Preheat Your Grill
When you’re ready to cook, preheat your grill or grill pan over medium-high heat. This will give your steak a nice sear and help lock in those delicious juices.
Step 4: Grill the Steak
Remove the flank steak from the marinade, allowing any excess marinade to drip off. Discard the leftover marinade. Place the steak on the grill and cook for about 4 to 6 minutes on each side, or until the internal temperature reaches your desired doneness (130°F for medium-rare, 140°F for medium).
Step 5: Rest and Slice
Once cooked, remove the steak from the grill and let it rest for about 5 to 10 minutes. This resting period allows the juices to redistribute throughout the meat, ensuring every bite is juicy and tender. After resting, slice the steak against the grain into thin strips.

Chef’s Rationale
The combination of coffee and soy sauce is not just for flavor; it also serves to tenderize the meat. Coffee contains natural acids and enzymes that break down tough muscle fibers, while soy sauce adds moisture and depth. The garlic and onion provide aromatic qualities that enhance the overall taste profile. This marination process transforms flank steak into a gourmet experience, making it suitable for any dining occasion.
Storage & Reheat Guide
If you have leftover Coffee and Soy Marinated Flank Steak, it can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, simply warm it in a skillet over low heat until heated through, or slice it and use it cold in salads and sandwiches for a refreshing meal.
Coffee and Soy Marinated Flank Steak Q&A

How do I know when my flank steak is cooked to the right doneness?
The best way to check the doneness of your steak is by using a meat thermometer. For medium-rare, aim for 130°F; for medium, it should be around 140°F. Remember that the steak will continue to cook slightly after being removed from the grill.
