We can’t stop making Marinated Flank Steak

I 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.

Serve flank steak and grilled vegetables in a warm flour tortilla topped with Pico de Gallo, guacamole, sour cream, and garnish with cilantro.

  • Marinade: 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.
  • Grill: Remove steak from the fridge about 20 minutes before grilling. Heat grill to high heat.
  • Clean and oil grill grates and add steak, discarding the marinade. Cook for 3-4 minutes, then flip to the other side and cook for 3-4 more minutes, or until desired doneness: 125 to 130°F for rare, 140°F for medium rare, and 150°F for medium.
  • Rest: Remove steak, cover with foil and rest for 5-10 minutes before slicing into very thin pieces, against the grain.


Peach Juice: You could even use one (14 oz) can of sliced peaches and puree the entire can–peaches, juice and all. Or sub White grape juice, pear juice or apple juice.

    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!

  2. 5 stars
    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!

  3. 2 stars
    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.

    1. 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.
