Tasty Marinated Flank Steak Grilled

Category: Simple Beef Recipes

Soak your steak for a couple of hours at least—in a simple blend of soy sauce, lemon juice, red wine vinegar, garlic, Dijon mustard, and Worcestershire sauce—for loads of flavor. Sear it quick on a medium-high grill to keep things juicy. Rest it when it's off the heat, then slice thin (go against the grain to keep each bite tender). This is perfect as your main dish or wrapped into sizzling fajitas. Super fast to prep and packed with big flavor, it’s perfect for backyard hangs or feeding the family.

With an easy marinade, this flank steak goes from budget-friendly to a juicy main course packed with flavor and super tender. The liquid mixture not only softens up the meat but loads every bite with zingy, savory tastes. Grill it up for a no-stress meal or slice thin for killer homemade fajitas.

This first hit my table during a Saturday BBQ when I needed something easy but crowd-pleasing. People cleaned their plates in seconds—it’s now my staple for steak tacos and salads.

Juicy Ingredients

  • Vegetable oil: Adds a mild backdrop that lets all other flavors shine and helps keep things from sticking to the grill. Fresh oil works best—skip anything that smells funky.
  • Low sodium soy sauce: Packs in crazy umami without going overboard on the salt. Aim for one without weird extra ingredients.
  • Red wine vinegar: Brings a light tang and also helps soften the beef. Grab one that smells bright and tasty.
  • Fresh lemon juice: Adds a fresh burst of citrus to lift things up. Choose lemons that feel weighty and juicy.
  • Worcestershire sauce: Provides a deep rich flavor that matches perfectly with beefy cuts. Go with classic American brands—they’re everywhere.
  • Dijon mustard: Gives a gentle spice and a touch of creamy texture. If French Dijon isn’t handy, any Dijon from your store will work.
  • Garlic, minced: Rounds out the whole mix with its bold aroma. Look for full, healthy cloves with smooth skin.
  • Ground black pepper: Adds a warm spice. Freshly cracked peppercorns make a world of difference in fragrance.
  • Flank steak: Satisfying beefy flavor and fast to cook. Seek out one with nice marbling and a fresh look.

Simple Instructions

Serve It:
Lay out the sliced steak on a platter. Dive in while it’s piping hot. Cold leftovers? They make awesome salads, sandwiches, or taco fillings.
Rest and Slice:
Move your steak to a cutting board and wait 5 minutes without touching it. Slicing right away makes the juices run out—waiting keeps it juicy. Cut into thin strips across the grain so bites stay tender.
Grill the Steak:
Take the steak out of the marinade and let the drips fall away. Ditch the rest of the marinade. Set steak on a hot grill, cook for 5 minutes, then flip and leave for another 5, or until it’s done how you like it. Medium-rare? It’ll stay nice and juicy.
Preheat the Grill:
Let the steak warm up at room temp for about 20 minutes before you toss it on. Brush the grill grates with a little oil so nothing sticks, then get it up to medium-high heat.
Marinate the Steak:
Put your steak in a shallow dish. Pour your marinade everywhere so all of it’s covered, flipping once or twice. Push plastic wrap on top and stash it in the fridge anywhere from 2 to 12 hours—longer means more flavor.
Make the Marinade:
Mix up the oil, soy, vinegar, lemon, Worcestershire, mustard, garlic, and pepper in a bowl. Stir well so you don’t see any separation and it’s glossy throughout.
Gather Ingredients:
Set all your ingredients near your workspace before starting. Clean off any silvery or tough skin from your flank steak—it gets chewy after cooking if left on.

Honestly, the umami and ping of tang from soy sauce and lemon make every bite a hit. My kids always wander into the kitchen once that mouth-watering smell fills the air, waiting for their favorite dinner.

Effortless Storage Tips

Stash sliced leftover steak in a sealed container in your fridge for up to three days. To reheat, use a skillet over low or zap for a few seconds in the microwave so it doesn’t dry out. Got extra? Freeze in a flat zip bag up to two months, and thaw overnight in your fridge.

Easy Ingredient Substitutions

No red wine vinegar? Apple cider or white vinegar can pinch-hit. Swap in spicy brown mustard if you want more kick. Regular soy sauce works fine—just watch your salt!

Hearty Serving Suggestions

Load up warm tortillas with steak, peppers, and onions for classic fajitas. Pair it alongside roasted potatoes and your favorite veggies for a solid meal. Put cold steak on salads or toss it in a bowl with rice and some fresh herbs for something new.

Vibrant Cultural and Historical Context

Ingredients

→ Marinade

01 0.5 teaspoon ground black pepper
02 2 cloves garlic, chopped up fine
03 15 millilitres Dijon mustard
04 22 millilitres Worcestershire sauce
05 30 millilitres freshly squeezed lemon juice

09 680 grams flank steak

Instructions

Step 01

Grab a mixing bowl, toss in the veggie oil, soy sauce, vinegar, lemon juice, Worcestershire, Dijon, garlic, and black pepper. Give it all a good whisk so it looks smooth and mixed up.

Step 02

Pop your steak in a 22 x 33-centimetre glass dish. Pour that marinade all over. Flip the steak over a few times to coat it nicely. Cover with plastic wrap. Stick it in the fridge for anywhere from 2 to 6 hours — or go for up to 12 hours if you want super tender, flavour-packed steak.

Step 03

Crank your outdoor grill up to about medium-high. Take a paper towel dipped in oil and wipe it over the grates so nothing sticks.

Step 04

Pull the steak out from the marinade and let any extra liquid run off. You can just toss the leftover marinade out.

Step 05

Set your marinated steak right on the hot grill. Cook for close to 5 minutes on each side, or more or less depending how you like it done.

Step 06

Move the steak to your cutting board. Let it hang out for five minutes so the juices don’t run out. Then slice it up thin, always cutting across the grain. Serve it up right away.

Notes

  1. You can always use regular soy sauce instead of the low-sodium kind if that’s what you have.
  2. Letting the steak soak in the marinade for a longer while really makes it extra juicy and rich tasting.
