Sharing is caring!

This is the juiciest grilled flank steak recipe. It's made with a fantastic marinade and grilled over high heat till tender.

This step-by-step guide on how to grill the best flank steak is simple and will be your new favorite way to prepare flank steak.

Flank steak is a lean cut of beef, so it's important to cook it correctly to optimize the flavor and tenderness.

You can serve this steak as a main course with a few sides or use it in a sandwich or steak salad. We love making flank steak tacos and serving them with sliced green onions and grilled pineapple salsa.

It keeps well in the refrigerator for several days, making it perfect for leftovers.

You can make this steak on a charcoal grill or gas grill, as long as you can get your grill super hot (400 degrees F or above). This is a quick sear recipe - we want to create a nice browned crust on the outside, leaving the interior juicy and tender. This is the best way to make a medium-rare steak.

Cooking Tips - If you are concerned about the steak sticking to your grill grates (sometimes older grill grates are 'stickier'), brush your grates with some olive oil or vegetable oil.

Slicing Steak - Make sure to slice your steak against the grain of the muscle fibers. This can make or break a steak! Here's a guide on slicing against the grain.

Recommended Tools - I highly recommend using an instant-read meat thermometer for this recipe.

Excess Marinade - If you want to reuse the leftover marinade, you can make it into a sauce. It needs to be boiled for 5 minutes to kill off any harmful bacteria from the raw steak.
