How to make Marinated Flank Steak:
- Make flank steak marinade: Add oil, soy sauce, peach juice, minced onion and parsley to a large Ziplock bag, or container. Add the steak and marinate for 3-6 hours.
- Grill on high heat for 3-4 minutes per side, or to desired doneness. Consult steak doneness chart below, for temperature guideline.
- TIP: Flank steak is such a thin cut of meat that you want to be able to sear the outside of the meat, without overcooking the inside. Make sure the grill is hot before placing meat on it. Also, keep in mind the steak will continue to cook as it rests, off the grill.
- Rest the steak on a cutting board covered in tinfoil for 5-10 minutes.
- Tip: Resting meat after grilling allows the juices to settle, making it juicier and more tender.
- Slice meat across the grain, at a diagonal, in VERY THIN slices.
- Tip: Notice the directional lines in the meat grain and slice perpendicular to them. If you cut along the grain, the meat will be tougher and chewier to eat.

Recipe
Marinated Flank Steak
Equipment
Ingredients
- 1 cup oil (vegetable or canola oil)
- 1 cup low-sodium soy sauce
- 1 cup peach juice or peach nectar*
- 2 Tablespoons dried minced onion
- 2 Tablespoons dried parsley flakes
- 1 flank steak
Instructions
- Add oil, soy sauce, peach juice, minced onion and parsley to a large ziplock bag.
- Add the flank steak to the bag, seal it, and lay it flat in your fridge to marinate for 3-6 hours.
- Remove the bag from the fridge about 15 minutes before grilling.
- Heat grill to high heat. Once the grill is hot, remove the steak from the bag of marinade (you can discard the marinade) and lay it on the grill.
- Cook for 3-4 minutes, then flip to the other side and cook for 3-4 more minutes, depending on how well done you like your steak. I don’t use a meat thermometer, but if you do, a general guideline is 125 to 130°F for rare, 140°F for medium rare, and 150°F for medium.
- Remove steak from the grill and place it on a cutting board. Cover it with a piece of tinfoil and allow it to rest for 5-10 minutes.
- Cut the meat across the grain, at a diagonal, in VERY THIN slices (almost “paper thin”). ENJOY!

It was eh. “London broils” don’t need anything more than simple Italian dressing marinate.
Peach with meat not only taste funky just sounds like they shouldn’t be together.
Go back to basics dear. You have have good shit out there but this one’s a flop.
What does the juice do for the steak?
Juice?
I love this recipe and so did my wife (who does not like steak of any kind). The flank was so juicy and tender. I will be making this again for sure. Flank Steak can be so tough and at the price of the meat, I was hoping it would turn out – we were not disappointed! I used organic peach nectar (from Amazon) and MCT Oil instead of Vegetable/Canola Oils. Also swapped out Coco Aminos for the Soy Sauce (which is a staple for us whenever Soy Sauce is required).
Thanks for this great recipe!

i wanted to clarify that you are saying you can use white grape juice, pear juice or apple juice for the juice, is that correct?
That is accurate
Can I cook this in a cast iron skillet instead of grilling?
Yes! Enjoy the steak!
I’m on a Keto diet and wondering what substitute for juice will still make it great?
Have you made this in the broiler instead of the grill? It’s about 10 degrees outside right now so looking for other options.
Yes! Works great!
Followed the recipe exactly, using apple juice instead of peach nectar. It was a hit!! Got compliments from everyone over for a bbq and even my husband is not a fan of steak and absolutely loved this recipe, turned out perfect. Your site is a staple for me and I’ve tried a ton of dishes and they’ve always been great. Thanks so much!
I had seen that you posted this on social media and decided to make it for my husband for Father’s Day. Usually, he’s the one grilling but I insisted. He said that was one of the best steaks he’s ever had (It was honestly because I followed your recipe exactly!) I know we will be making it again soon. Thanks!
How do you think this would do in the Instant Pot?
I wouldn’t suggest pressure cooking it. Sorry. This type of steak just cooks so quickly and really tastes best grilled.
Could you another oil, like avacado?
I’m sure that would be fine 🙂
Can’t wait to try, someone asked about overnight marinating. I’m not a fan of that with the soy sauce it can be tough, its the salt base. Morning to Dinner is perfect! Thank you for sharing recipe, I’ll be making this weekend.
This recipe is delicious! We had left over flank steak for several meals and it was as tasty and tender as when it came off the grill.
you write 1 flank steak for 5. what weight flank steak did you buy?
The average Flank Steak is about 1.7-2.5 lbs., which should feed 5 adults. Especially when sliced thinly against the grain.
Made this marinade exactly as directed and it rocked!!!!! I’ve never tasted better skirt steak. The meat was tender, not tough or even slightly chewy. Tasted AMAZING!
This sounds amazing! Question, how much fat should there be on a skirt steak? I bought one from a real butcher/meat counter and its beautiful, but it has a big slab of fat on one half of the meat. Do I ignore it or do I trim it?
I always use Flank Steak from Costco, has very little fat. I think I would trim it as much as possible.
I would grill it with the fat intact. It will enhance the taste and you can always trim it off later.
I live in an apartment and we don’t have a grill. Would putting it in the broiler work? If so, any recommendations?
Yes, broiler should work. Heat broiler as hot as possible. When first side is
browned and broiling turn steak and repeat. Watch carefully to not over cook, similar to grill.
heated cast iron grill pans are great for steaks too.
I have some pineapple juice. I wonder if that would work???
Sure!
How did the pineapple juice work out?
This was really good. The marinade will be a go to for other meats. I had more char than the picture shows but I tend to like a good crust for meats.
Could you marinate it overnight?
Yes you can! I hope you enjoy it!
This was very easy to make and out of this world good. Thanks for the tips
This was absolutely delicious! Thanks for all the tips as well.
