Ingredients You’ll Need
- Soy sauce: forms the savory, salty base of the marinade and tenderizes the meat; use a low-sodium version if you’re watching your salt intake.
- Olive oil: adds richness and helps carry the flavors into the steak while preventing sticking on the grill.
- Fresh lemon juice: provides the essential bright, tangy acidity that balances the soy sauce’s saltiness; bottled juice just won’t give you the same fresh kick.
- Worcestershire sauce: introduces a deep, savory umami flavor with a hint of sweetness that rounds out the marinade beautifully.
- Garlic: minced garlic infuses the steak with its aromatic, pungent flavor; fresh cloves are always better than pre-minced.
- Dijon mustard: acts as an emulsifier to help the marinade cling to the meat while adding a subtle, complex sharpness.
- Black pepper: freshly ground pepper gives a warm, pungent bite that’s essential to the flavor profile.
- Smoked paprika: delivers a subtle smokiness and a lovely red color, even before the steak hits the grill.
- Red pepper flakes: these are optional but they add a pleasant, gentle heat that builds with each bite.
- Flank steak: a lean, flavorful cut with long muscle fibers that become incredibly tender when sliced correctly against the grain.
- Fresh parsley: a final sprinkle of chopped parsley adds a pop of fresh color and a clean, herbal note.
- Cilantro, lemon wedges, green onions: these optional garnishes let you customize each plate with extra freshness, brightness, and color.
How to Make It
Whisk the Marinade:
Grab a medium bowl and whisk together the soy sauce, olive oil, lemon juice, Worcestershire, garlic, Dijon, pepper, paprika, and optional red pepper flakes. You want everything fully combined so the oil emulsifies slightly, creating a cohesive sauce that will coat the steak evenly.
Marinate the Steak:
Place your flank steak in a large resealable bag or a shallow dish, then pour the marinade all over it. Turn the steak a few times to make sure every surface is coated. This step is where all that incredible flavor starts to build.
Let It Rest and Absorb:
Seal the bag or cover the dish and pop it in the refrigerator. Let it marinate for at least four hours, but if you can plan ahead, overnight is truly the game-changer for deep, penetrated flavor. Try to turn the steak once if you remember.
Preheat and Prep the Grill:
About 30 minutes before you’re ready to cook, pull the steak from the fridge to take the chill off. Preheat your grill to a solid medium-high heat, around 400-450°F. Give the grates a good brush and a light oiling to prevent any heartbreaking sticking.
Grill to Your Perfect Doneness:
Take the steak out of the marinade and let the excess drip off; discard the used marinade. Place it on the hot grill and cook undisturbed for about 5 to 7 minutes per side. You’re aiming for beautiful grill marks and an internal temperature of 130-135°F for medium-rare.
The Crucial Rest:
Once it’s off the grill, transfer your marinated flank steak grilled to perfection onto a clean cutting board. Let it rest, untouched, for a full 10 minutes. This isn’t optional—it lets the juices settle back into the meat so they don’t all run out when you slice.
Slice Against the Grain:
This is the most important step for tenderness. Find the direction of the long muscle fibers, then take a sharp knife and slice thinly across them, perpendicular to their run. You’ll see the difference immediately in how tender each piece is.
Garnish and Serve:
Arrange those beautiful slices on a platter and sprinkle generously with the chopped parsley and any of your chosen optional garnishes. Serve it right away with lemon wedges on the side for a final squeeze of bright acid.

Storage Tips
Store any leftover marinated flank steak grilled and sliced in an airtight container in your fridge; it’ll keep beautifully for 3 to 4 days. I love using the cold slices straight from the container in salads or wraps for an easy lunch. For longer storage, wrap the slices tightly in plastic wrap or foil, place them in a freezer bag, and freeze for up to 3 months. Thaw them overnight in the refrigerator and reheat gently in a skillet with a splash of broth or water to keep them moist, as the microwave can make them tough.
Ingredient Substitutions
If you’re out of fresh lemons, lime juice or even a good quality red wine vinegar can stand in for that needed acidity in the marinade. For a gluten-free version, simply swap the regular soy sauce for tamari and use a certified gluten-free Worcestershire sauce. Don’t have Dijon? A spoonful of regular yellow mustard or even a bit of stone-ground mustard will work in a pinch. If smoked paprika isn’t in your spice cabinet, sweet paprika plus a tiny drop of liquid smoke can mimic that flavor, or you can just use more black pepper. The fresh parsley garnish can easily become fresh cilantro, chives, or even thinly sliced basil depending on what you have growing.
Serving Suggestions
This marinated flank steak grilled is incredibly versatile. For a classic dinner, I serve it alongside garlic mashed potatoes and a crisp arugula salad. It’s also fantastic with grilled asparagus or zucchini right off the same grill. If you’re feeling like a fiesta, warm up some tortillas and set out salsa, guacamole, and cotija cheese for amazing steak tacos. For a lighter meal, slice it over a big bed of greens with cherry tomatoes and a tangy vinaigrette, or pair it with a simple rice pilaf that soaks up any delicious juices left on the platter.
Cultural Context
Flank steak holds a special place in American backyard grilling culture, prized for its bold beefy flavor and affordability. While its roots are in butchery’s utilization of leaner cuts, it gained fame through methods like this, where a robust marinade tenderizes it for the grill. This particular recipe reflects a melting-pot approach with soy sauce introducing an umami depth popularized in mid-century American cooking, combined with classic Western grill seasonings. It’s a testament to how a great technique—marinating and high-heat grilling—can elevate an everyday cut into centerpiece status for casual gatherings and weeknight dinners alike.

Frequently Asked Questions
For a gluten-free alternative, you can use tamari or coconut aminos. While the flavor profile will change slightly, both will provide the necessary savory, umami base that soy sauce contributes to this marinated flank steak grilled.
Absolutely. You can marinate the steak for up to 24 hours in the refrigerator, which will only deepen the flavor. After grilling and resting, the sliced steak can be stored in an airtight container for 3-4 days, making it perfect for meal prep.

For medium-rare, grill for about 5-7 minutes per side over high heat. The best method is to use an instant-read thermometer; aim for 130-135°F internally. Remember, the temperature will rise about 5 degrees while the steak rests.
It pairs perfectly with classic American sides. Think grilled vegetables, a crisp green salad, roasted potatoes, or corn on the cob. The savory, juicy sliced steak is also fantastic in tacos or on top of a hearty salad for leftovers.
