This rosemary garlic flank steak is sure to become your new favorite recipe for grilling steak!
This marinated flank steak is great for the summer because it just takes a few minutes on the grill, and you’ll have a perfect steak that’s great on its own or on top of a fresh garden salad. You can make the marinade the day before if you know you’re going to have a busy day, or you can whip it together just 30 minutes before grilling. You’ll get amazing flavor either way.
Rosemary Garlic Marinade
This macro-friendly marinade is so easy to pull together, and it’s really packed with flavor. You only need a few ingredients to make it:
- Apple cider vinegar
- Fresh rosemary
- Fresh oregano
Combine everything in a small bowl and whisk together to combine all the flavors. After you’ve trimmed any obvious fat off your flank steak, place the steak in a shallow dish or a large resealable bag. (If you know you want small slices of flank steak when you’re finished, then you can cut the flank steak in half lengthwise before pouring the marinade over it.)
Then pour the marinade over the steak. The steak will be delicious and ready to cook after 30 minutes of marinating. But if you have more time, you can marinate this steak overnight in the fridge for even more flavor. Just remember to pull it out of the fridge about 30 minutes before you plan on cooking it so it can come to room temperature.
How to Cook Rosemary Garlic Flank Steak
When your steak is done marinating, then it’s time to cook! You can cook this steak on either the grill or in a cast iron skillet on the stove. Heat your grill or cast iron skillet to high heat, and spray with avocado oil. Let it get nice and hot!
Take your steak out of the marinade and sprinkle each side generously with kosher salt and a few cracks of pepper. Then sear the steak for 3-4 minutes per side. Depending on the thickness of the steak, you might need to sear it for slightly longer or shorter. Just keep an eye on it, and use a thermometer to check its internal temperature. You want to remove the steak when it reaches 130°. Remember that it will keep cooking even after you pull it off the heat.
Place the flank steak on a plate and loosely tent it with foil. Let it rest for about 5 to 10 minutes before slicing it thinly against the grain. Slicing against the grain is so important! Whichever way you see the lines running in the meat, cut perpendicular to that to avoid tough hunks of meat. Try to slice at a slight angle for prettier slices.
