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.

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?
