Ingredients You’ll Need

1½ lbs flank steak: This cut is known for its rich flavor and tenderness when cooked properly. It’s great for grilling and can easily serve four people.
½ cup olive oil: Used as a base for the marinade, it adds moisture and helps the spices adhere to the meat. Extra virgin is recommended for its robust flavor.
3 cloves crushed garlic: Fresh garlic adds aromatic depth and enhances the marinade’s overall profile.
¼ cup low sodium soy sauce: Brings umami to the dish while keeping salt levels in check. You may substitute with coconut aminos for a soy-free option.
⅓ cup balsamic vinegar: Offers a sweet tang that complements the beef beautifully. If you like more tartness, you can use red wine vinegar.
2 tablespoons Worcestershire sauce: This adds a unique flavor that rounds out the marinade, giving it a savory kick.
2 tablespoons brown sugar: Balances acidity and brings sweetness to the marinade. Feel free to adjust based on preference.
2 tablespoons lime juice: Freshens up the marinade and adds a zesty punch. Lemon juice can be an excellent substitute if needed.
1½ tablespoons stone ground mustard: Its grainy texture adds complexity, enhancing flavor without overpowering the steak.
½ teaspoon fresh ground black pepper: Freshly ground gives a sharper flavor that elevates the taste of the steak.

How to Make Grilled Flank Steak

Prepare the Marinade: In a large Ziploc bag or bowl, combine ½ cup olive oil, 3 crushed cloves of garlic, ¼ cup low sodium soy sauce, ⅓ cup balsamic vinegar, 2 tablespoons Worcestershire sauce, 2 tablespoons brown sugar, 2 tablespoons lime juice, 1½ tablespoons stone ground mustard, and ½ teaspoon fresh ground black pepper. Whisk until well blended.
Marinate the Steak: Add the 1½ lbs of flank steak to the marinade, seal the bag or cover the bowl, and refrigerate for at least 6 hours, preferably overnight. Be sure to turn the meat a few times to ensure even marination.
Preheat the Grill: When you’re ready to cook, preheat your grill to medium-high heat, around 450 degrees Fahrenheit.
Grill the Steak: Using tongs, remove the steak from the marinade and place it on the grill. Discard any leftover marinade. Cook for 4-5 minutes on each side, depending on your desired doneness. Avoid moving it around too much to achieve a good sear.
Rest and Slice: Remove the steak from the grill once cooked to your liking. Cover it loosely with aluminum foil and let it rest for 10-15 minutes to keep it juicy. After resting, slice the steak against the grain at a sharp diagonal using a serrated knife. Season with kosher salt and fresh ground black pepper to taste before serving.

Storing & Reheating

To store grilled flank steak, place leftovers in an airtight container and refrigerate for up to 3 days. If you plan on storing for a longer time, wrap portions tightly in plastic wrap or store in a freezer-safe container, where they’ll last for up to 3 months. To reheat, thaw the steak overnight in the fridge, then warm gently in a skillet over low heat for about 5-7 minutes, turning occasionally. Keep in mind that reheating may change the texture slightly, but you can refresh its flavors with a squeeze of lime juice before serving.

Chef’s Helpful Tips

Make sure your flank steak is at room temperature before grilling; this helps it cook evenly.
Avoid over-marinating; while 6 hours is perfect, anything beyond 24 hours can cause the meat to become mushy due to the acid in the marinade.
For perfect grill marks, place the steak on one side for the first half of cooking without moving it.
Use a meat thermometer! The ideal internal temperature for medium-rare is 130-135°F, while medium is 140-145°F.
Slicing against the grain is crucial for tenderness; take a moment to identify the grain direction for the best results.

Recipe FAQs

Can I use a different cut of beef instead of flank steak?

Absolutely! While flank steak is ideal for its flavor and texture, you can substitute it with skirt steak or sirloin. Both alternatives will provide a delicious result, but will require attention to cook time, especially thinner cuts.

How do I know when my flank steak is done cooking?

To determine doneness, use a meat thermometer to check the internal temperature. Aim for 130-135°F for medium-rare or 140-145°F for medium. You can also press the steak gently; it should feel firm but still spring back slightly for a perfect finish.

Can I make the marinade ahead of time?

Yes! The marinade can be prepared a day in advance and stored in the fridge until you’re ready to use it. This saves time when you’re ready to cook, allowing flavors to deepen even more.

Can grilled flank steak be served cold?

Definitely! Grilled flank steak makes for a great cold dish, perfect for salads or sandwiches. Just make sure it’s cooled completely before refrigerating, and it will last for up to 3 days in the fridge. Enjoy it sliced cold on a salad for a refreshing meal!
