Ingredients You’ll Need

1½ lbs flank steak: This cut is known for its flavor and relatively short cooking time, ideal for grilling.
½ cup olive oil: This helps to tenderize the meat while adding rich flavor; you can substitute with avocado oil for a similar taste.
3 cloves crushed garlic: Fresh garlic adds aromatic depth to the marinade; feel free to use garlic powder in a pinch.
¼ cup low sodium soy sauce: Provides umami and helps to enhance the steak’s natural flavors; alternatives include tamari for a gluten-free option.
⅓ cup balsamic vinegar: Adds a sweet-tart complexity; apple cider vinegar can serve as a substitute if needed.
2 tablespoons Worcestershire sauce: This contributes a savory kick that balances the sweetness of the brown sugar.
2 tablespoons brown sugar: It helps to caramelize the steak while grilling, creating a lovely crust; coconut sugar can be a healthier substitute.
2 tablespoons lime juice: The acidity brightens the marinade; lemon juice can also work well here.
1½ tablespoons stone ground mustard: Gives a slight tang and depth; yellow mustard can be used if that’s your preference.
½ teaspoon fresh ground black pepper: This adds a bit of heat; feel free to adjust for your taste.

How to Make Grilled Flank Steak

Prepare the Marinade: In a large Ziploc bag or bowl, mix together ½ cup olive oil, 3 crushed garlic cloves, 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. Stir well to combine.
Marinate the Steak: Add the flank steak to the marinade, ensuring it’s fully submerged. Seal the bag or cover the bowl and refrigerate it for at least 6 hours, or ideally overnight. Be sure to turn the steak several times to let all sides absorb the flavors.
Preheat the Grill: When you’re ready to grill, preheat your grill to medium-high heat, around 450 degrees Fahrenheit.
Grill the Steak: Remove the steak from the marinade, allowing excess liquid to drip off. Discard the leftover marinade. Place the steak on the grill and cook for about 4-5 minutes on each side for medium-rare, adjusting the time according to your preference. Avoid moving the steak to allow for a perfect sear.
Rest and Slice: Once cooked to your liking, remove the steak from the grill and cover it loosely with aluminum foil. Let it rest for 10-15 minutes. To serve, slice against the grain at a sharp diagonal and season with kosher salt and fresh ground black pepper to taste.

Storing & Reheating

Store any leftover grilled flank steak in an airtight container in the refrigerator for up to 4 days. If you’d like to keep it longer, you can freeze it for up to 3 months. Just make sure to wrap it tightly in plastic wrap or aluminum foil before putting it in a freezer-safe bag. When it’s time to enjoy again, reheat the steak gently in the oven at 350 degrees Fahrenheit until warmed through. Keep in mind that reheating may slightly alter the texture, but a splash of fresh lime juice can help refresh the flavors.

Chef’s Helpful Tips

To ensure the most tender steak, slice against the grain—it makes a significant difference in texture!
Make sure to let your flank steak rest before slicing; this allows the juices to redistribute for maximum flavor and juiciness.
For even more flavor, consider adding fresh herbs like rosemary or thyme to your marinade.
If you’re using wooden skewers for skewered flank steak, remember to soak them in water for 30 minutes before grilling to prevent burning.
Flank steak is great for meal prep; grill a larger piece and cut it down for salads or wraps throughout the week.

Grilled flank steak is not just a dish; it’s a memory in the making. It’s quick, effortless, and filled with an abundance of flavors. Whether you’re treating your family to a delightful dinner or firing up the grill for guests on a sunny afternoon, this steak will surely impress. Feel free to play with the marinade’s flavors, add your twist, and make it your own!

Recipe FAQs

Can I use another cut of beef for this recipe?

Absolutely! While flank steak is the star here, you can use skirt steak or sirloin as alternatives. Keep in mind that different cuts may require slight adjustments in cooking times for optimal tenderness.

How do I know when the steak is done?

Using a meat thermometer is the best way to check for doneness. For medium-rare, aim for an internal temperature of 130-135 degrees Fahrenheit. Remember, the steak will continue to cook slightly as it rests.

Can I marinate the steak for too long?

While marinating adds great flavor, allowing it to sit for more than 24 hours can lead to a mushy texture since acids break down the meat fibers too much. Stick to 6 hours up to overnight for the best results!

What can I serve with grilled flank steak?

This steak pairs beautifully with various sides! Think grilled vegetables, a fresh salad, or classic garlic mashed potatoes. You can even slice it up for tacos or burritos, making it a versatile centerpiece for any meal.
