We can’t stop making Marinated Flank SteakI have to give credit for this Marinated Flank Steak recipe to my Mom, who perfected it decades ago. It made regular appearances on our Sunday dinner table for as long as I can remember!
The flank steak marinade can be made ahead of time, with ingredients I always have on hand, and the taste is incomparable. Plus, flanks steak cooks quickly, so it’s one of the easiest things you can grill. Be sure to check out all of my tips for how to grill a steak!
How to make Marinated Flank Steak:
Steak Marinade: Add oil, soy sauce, peach juice, minced onion, and parsley to a large Ziploc bag, or container. Add the steak then marinate for 3-6 hours.
Grill: Flank steak is a thin cut of meat and you want to sear the outsides without overcooking the inside. Make sure the grill is preheated hot. And keep in mind the steak will continue to cook as it rests off the grill. We cook our flank steak on high heat for 3-4 minutes per side.
Rest the grilled flank steak for 5-10 minutes, covered with aluminum foil to keep warm.
To Serve: Slice meat across the grain, at a diagonal, in VERY THIN slices.
Recipe Variations:
- Marinated Flank Steak Fajitas: Slice a couple bell peppers and an onion then season with salt and pepper. Cook on a very hot skillet or grill pan with oil for a few minutes. Serve flank steak and grilled vegetables in a warm flour tortilla topped with Pico de Gallo, guacamole, sour cream, and garnish with cilantro.
- Marinated Flank Steak Tacos: Serve flank steak in a warm corn tortilla topped with Pico de Gallo or 5 minute salsa, avocado, and other favorite toppings.
- Steak Salad: Serve on a bed of greens, with red onion, avocado, cherry tomato, cucumber, grilled corn, gorgonzola or bleu cheese.

I know your mom, have for decades, and the peach juice intrigued me. I immediately thought of Trader Joe’s peach juice. I knew it would be good and it was!
This was really good and so easy. Although I cut the marinade ingredients in half and still had plenty of marinade for the steak. The peach nectar imparted a great flavor – less sweet than the usual honey or maple syrup. This is a keeper for sure!
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.
This had a totally different flavor profile than Italian Dressing. There are numerous recipes that use orange juice and soy for a marinade and the peach nectar was a creative change to the normal marinade ingredient. More importantly, this was a cleaner recipe than using a processed ingredient like a bottle of store-bought dressing.
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.
