What You Need to Make Sweet Garlic Spiced Marinade

This marinade is sweet and garlicky– and obviously “macro-friendly” (which is mostly going to mean it’s not full of olive oil which sneaks in fat and calories you might find are totally unnecessary.) The warm spices play so nicely with grilled, savory flank steak. Here’s what you’ll need to cook your flank steak…

  • Apple cider vinegar
  • Brown sugar
  • Minced garlic (or frozen cubes of garlic)
  • Cumin
  • Chili powder
  • Paprika

Most of these ingredients are, at least for me, pantry staples. YAY! No big grocery run–a total lifesaver. Just grab some flank steaks, and if you buy a few extra, throw a couple in the freezer for next time while you’re at it! You can even add the marinade first for a really easy dinner in the future! Nothing (except maybe my meal plan or cookbooks) makes macro-counting easier than having pre-made or easy-to-make proteins on hand.

One of the best parts about this marinade is that you can leave it on for just 30 minutes if you are low on time, or make it in the morning and let it sit in the fridge for up to 6 hours. Obviously, more time lets it sink in a bit more, but I’m the world’s worst planner, so we’re usually just letting it sit on the counter for 30. Either way, it’ll be amazing!

How to Make Sweet Garlic Spiced Grilled Flank Steak

To make this Sweet Garlic Spiced Grilled Flank Steak all you have to do is marinate and grill your flank steak, and dinner will be ready in no time! To start, combine the marinade ingredients in a small bowl. Just whisk everything together, making sure the brown sugar smooths out and isn’t lumpy.

Next, using a sharp knife, trim any obvious fat off your flank steak. There’s nothing better than a good, sharp knife. No kitchen gadget does it better, IMO. It makes cooking and preparing dinner SO much easier. These Nakano are my absolute favorite!

After trimming your lean cut of steak, place it in a shallow dish or a large resealable bag to pour the marinade over the steak.

Then, you can either let it sit out at room temperature for 30 minutes, or you can put the marinating steak in the fridge for up to 6 hours. If you decide to put the steak in the fridge, pull it out at least 30 minutes before you cook it. You’ll want to bring it up to room temperature before grilling.

Grilling Your Flank Steak

When you’re ready to cook your steak, either heat a cast iron skillet over high heat or fire up your grill. Be sure to spray your skillet or grill with a little bit of avocado oil to prevent sticking.

While things are heating up, remove your steak from the marinade, letting any excess marinade drip off. Sprinkle each side of your flank steak with good amounts of kosher salt and cracked pepper. Then, sear for 3-4 minutes on each side. The amount of time you need to cook depends, of course, on the steak’s thickness. So just keep an eye on it, and use a meat thermometer to check for doneness. Make sure to pull it off the heat when the internal temperature reaches 130° because it will keep cooking off of the grill or skillet.

What is Slicing Against the Grain?

After pulling the cut of meat off the grill, place the flank steak on a plate or cutting board and tent it with aluminum foil. Let it rest for 10 minutes before slicing against the grain.

I know this seems like a small thing, but slicing against the grain makes all the difference! You’ll avoid those tough hunks of meat that pull out of your sandwich (which is where our leftovers go) on the first bite.

To slice against the grain, take a minute to see which way the lines are running through the meat. Then cut perpendicular to those lines, and you’ll create bites of meat that are tender instead of tough.
