Flat Iron Steak Marinade

Food for a family of 6 is rarely gourmet, especially with food allergies, a toddler, and a picky eater. If you are looking for a kid pleasing and fast dinner, this flat iron steak is sure to be a crowd favorite . We paired it with some dairy free mac and cheese and a veg. My cashew “cheese” sauce (1 small sweet potato, 1c water, 1/2c soaked cashews, 1/4 cup nutritional yeast, salt to taste (formal recipe to come soon, but you get the idea). The flat iron steaks are one of our kids favorites and my fastest cooking meats in our arsenal. It’s so tender and an easy marinade with ingredients you likely already have in your kitchen.


  • 1 Tbs coconut aminos
  • 1 Tbs Apple Cider Vinegar (I like the one from Trader joes because its so affordable but any will work, or soy sauce if you eat soy)
  • 1/2Tbs Olive Oil
  • 1 tsp ground ginger
  • a pinch of salt
  • pepper to taste
  • Soak the sliced meat in a ziplock or bowl for at least one hour with your marinade.

Wash and dry a flat iron steak. We get ours from our Butcher Box subscription.
Slice the meat across the grain in half-inch slices and then tenderize the meat with a meat tenderizer or something heavy with a flat bottom until the strips are wide and flat and a similar thickness.

Preheat a large skillet to medium high heat, then spread the meat slices out flat and let them cook for about 30-60 seconds per side, depending on the thickness and how rare you like your meat. We like ours medium-well.

The best part of this dish is that it takes about .2 seconds to cook and the kid love how the meat is sweet and juicy. I use a cast iron skillet so cleanup is a cinch.
