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.

Equipment

Cutting board

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!

Notes

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

Variations:
