I love this marinated flank steak because it’s full of flavor and super easy to make. It’s one of those recipes that turns a simple dinner into something special without much effort. I can’t wait for you to try it and see how juicy and tasty it gets after soaking in the marinade.
Most of the ingredients in this recipe are common in many kitchens, like olive oil, garlic, and black pepper. The red wine vinegar might be less familiar if you don’t usually cook with vinegar, but it adds a nice tang that balances the soy sauce. If you don’t have dried oregano, you can find it in the spice aisle at the supermarket or substitute with Italian seasoning.

Ingredients For Marinated Flank Steak Recipe
Soy sauce: Adds a salty, savory flavor that helps tenderize the steak.
Olive oil: Keeps the meat juicy and helps the marinade coat the steak evenly.
Red wine vinegar: Gives a slight tang and helps break down the meat fibers for tenderness.
Garlic: Brings a fresh, aromatic punch to the marinade.
Dried oregano: Adds a warm, earthy herb flavor.
Black pepper: Gives a mild heat and depth to the taste.
Flank steak: A lean cut of beef that’s perfect for grilling and soaking up marinades.
Technique Tip for This Recipe
One of the most important steps in this Marinated Flank Steak Recipe is letting the steak rest after you take it off the grill. It might seem like you want to dig in right away, but giving it a few minutes to rest makes a big difference. Here’s how to do it:
- When your steak is done cooking, take it off the grill and place it on a clean plate or cutting board.
- Let it sit there for about 5 minutes without cutting into it.
- After resting, slice the steak against the grain (that means cutting across the lines you see in the meat, not along them).
Why does this help? When you cook meat, the juices inside get pushed toward the center. If you cut it right away, those tasty juices spill out and your steak can end up dry. Resting lets the juices spread back through the meat, so every bite stays juicy and flavorful.
I remember the first time I skipped resting because I was too hungry. The steak looked great, but it was kind of dry and not as tender as I hoped. Now, I always wait those few minutes, and it’s totally worth it. Also, slicing against the grain makes the meat easier to chew because it breaks up the muscle fibers. It’s a small step that makes eating your steak way more enjoyable.
So next time you grill flank steak, give it a little break before slicing. Your taste buds will thank you!

How to Store / Freeze Your Flank Steak
To store your marinated flank steak, place it in an airtight container or resealable plastic bag. Ensure that the container is tightly sealed to prevent any air from getting in, which can cause the meat to dry out.
If you plan to consume the steak within a few days, keep it in the refrigerator. It will stay fresh for up to 3-4 days. Make sure to label the container with the date to keep track of its freshness.
For longer storage, freezing is an excellent option. Lay the marinated steak flat in a resealable plastic bag, removing as much air as possible before sealing. This helps to prevent freezer burn and maintain the quality of the meat.
If you want to freeze the steak for an extended period, consider using a vacuum sealer. This method removes all the air from the packaging, ensuring the meat stays fresh for up to 6 months.
When you're ready to cook the frozen steak, transfer it to the refrigerator to thaw. This slow thawing process helps to maintain the texture and flavor of the meat. Allow at least 24 hours for the steak to thaw completely.
If you're in a hurry, you can use the cold water method to thaw the steak. Place the sealed bag in a bowl of cold water, changing the water every 30 minutes. The steak should be ready to cook in about 1-2 hours.
Once thawed, cook the steak as per the original recipe instructions. Remember to discard any leftover marinade that has been in contact with raw meat to avoid any risk of contamination.
If you have leftover cooked flank steak, store it in an airtight container in the refrigerator. It will remain good for up to 3 days. Reheat gently in a skillet or microwave to avoid drying out the meat.
