How to Make Flank Steak Marinade?
Flank steak gets its signature tenderness and flavor from a well-balanced marinade, and this recipe couldn’t be easier to follow.
Whisk the Marinade
Combine the soy sauce, olive oil, vinegar, Worcestershire sauce, honey, mustard, garlic, and hot sauce in a mixing bowl. Add the cayenne, paprika, red pepper flakes, oregano, cumin, and a pinch of salt and pepper. Mix everything together until smooth. This is where the magic begins!
Marinate the Steak
Place the flank steak in a resealable plastic bag or shallow baking dish. Pour the marinade over the steak, ensuring it’s completely covered. Massage the marinade into the meat to help the flavors penetrate. Seal the bag or cover the dish and refrigerate for at least 1 hour, but overnight is best for deeper flavor.
Heat the Grill
When you’re ready to cook, preheat your grill or grill pan to medium-high heat. Lightly oil the grill grates to prevent sticking.
Grill the Steak
Remove the steak from the marinade, letting the excess drip off, and place it on the grill. Discard the marinade. Grill for about 3-4 minutes per side for medium-rare, or adjust cooking time based on your preferred doneness. Use a meat thermometer for precision (125°F for rare, 135°F for medium-rare).
Rest and Slice
Transfer the steak to a cutting board and cover it loosely with aluminum foil. Allow it to rest for 10 minutes; this locks in all those delicious juices. When slicing, cut against the grain into thin strips for maximum tenderness.

Make Ahead and Storage
If you’re planning ahead, this marinade makes life easier. You can prepare it in advance and store it for when you’re ready to marinate your steak.

Tips for Making the Recipe
Having made this marinade several times, I’ve picked up a few tricks to get the most out of it. Here’s what I’ve learned:
- Don’t skip the resting time. Allowing the steak to rest before slicing ensures it stays juicy.
- Use fresh garlic. It makes a big difference in flavor over garlic powder.
- Marinate longer if possible. Overnight marination really intensifies the flavors.
- Experiment with heat. Add more hot sauce or cayenne if you like it spicier.
- Taste before grilling. Adjust your marinade for balance if you like it more tangy or sweet.

How Do Chinese Tenderize Flank Steak?
Chinese cooking often uses techniques like velveting to tenderize flank steak. This involves coating the meat in a mixture of cornstarch, baking soda, and egg whites before lightly stir-frying it.
Marinating the meat in soy sauce, rice wine, or vinegar also helps to break down tough fibers, resulting in a melt-in-your-mouth texture.
Why Is My Flank Steak Always Tough?
The secret to tender flank steak lies in handling it right. This cut has long, tough muscle fibers, so make sure to marinate adequately and slice against the grain. Overcooking it can also make it chewy, so aim for medium-rare and use a thermometer to get the doneness just right.
This mouthwatering flank steak marinade recipe is sure to become one of your favorites! Follow the steps, customize it to your taste, and enjoy flavorful, tender steak every time. Happy grilling!
