Ingredients
- Vegetable oil: Creates a plain foundation that carries the other tastes and stops the meat from sticking when grilling. Go for something fresh without any weird smell.
- Low sodium soy sauce: Adds rich meaty flavor without too much salt. Try to find one without fake additives.
- Red wine vinegar: Gives a light zip and helps soften the meat. Pick one with a clean strong smell.
- Fresh lemon juice: Adds zing and lightness. Choose lemons that seem weighty for their size.
- Worcestershire sauce: Brings complicated savory notes that work great with beef. The old-school brands taste the best.
- Dijon mustard: Adds mild warmth and smooth texture. Try to get authentic French Dijon if you can.
- Garlic, minced: Fills out the flavor mix with fragrant depth. Look for plump, clean cloves.
- Ground black pepper: Supplies a warm spicy touch. Crush whole peppercorns right before using for the strongest aroma.
- Flank steak: This cut has amazing beef flavor and cooks quickly. Pick one with nice fat streaks and no dull gray areas.
Instructions
- Collect Everything:
- Set out all the marinade stuff and your steak so you don't forget anything. Take time to cut off any tough silvery skin from the flank steak since it'll stay chewy after cooking.
- Mix Up The Marinade:
- Stir together the oil, soy sauce, red wine vinegar, fresh lemon juice, Worcestershire sauce, Dijon mustard, garlic, and black pepper in a bowl. Keep mixing until everything looks shiny and blended with no separate layers.
- Soak The Steak:
- Put the flank steak in a shallow glass dish just large enough for the meat to lie flat. Pour marinade all over the steak then flip it a couple times to coat every part. Press plastic wrap right on top and stick it in the fridge for at least 2 hours but up to 12 hours for the most tender results.
- Get The Grill Ready:
- About 20 minutes before cooking time, take the steak out of the fridge so it warms up slightly. Heat your grill to medium-high and rub the grates with oil to prevent sticking.
- Cook The Steak:
- Pull the steak from the marinade and let extra liquid drip back into the dish. Throw away the used marinade. Set the meat on the hot grill and leave it alone for 5 minutes. Flip it with tongs and cook another 5 minutes or until it reaches how done you like it. For juiciest results, aim for medium rare.
- Let It Rest Then Cut:
- Transfer the cooked steak to a clean board and don't touch it for 5 minutes. This keeps all the juices inside. After resting, cut the steak into thin slices across the grain for maximum softness.
- Enjoy:
- Put the slices on a plate and eat right away while still warm. Any leftovers make great sandwich fillings or fajita meat.

What I love most about this dish is how the soy sauce and lemon work together to make the meat taste amazing. My kids always hang around the kitchen when they smell it cooking because they know something yummy's coming.
Storage Tips
Keep any extra steak slices in a sealed container in the fridge for up to three days. When reheating, use gentle heat in a pan or short bursts in the microwave to keep it juicy. You can freeze cut steak flat in freezer bags for up to two months and thaw in the fridge overnight.
Ingredient Substitutions
Don't have red wine vinegar? Apple cider or white vinegar will work too. You can switch Dijon for spicy brown mustard if you want more kick. Regular soy sauce can replace low sodium but watch out as your dish might get saltier.
Serving Suggestions
Stuff the soft steak into warm tortillas with colorful peppers and onions for fajitas. Pair with crispy potatoes and grilled veggies for a filling dinner. Leftover meat tastes wonderful on top of fresh greens or mixed into a bowl with rice and herbs.
