How to make a Flank Steak on the Blackstone

This is just the overview so you can see what you’re actually getting into here. When you are cooking, you’ll want to use the full recipe at the bottom of the page.



Fire up the griddle and get it heating up over medium-high heat.



Pat the steak dry on both sides and season the steak with salt and pepper.



Put half your butter down and put the steak on top. Gently press down to ensure you’re getting that good sear. Let it brown and then flip and sear the other side.


Monitor temps

Make sure you are monitoring the temp of the steak as you sear that second side. Flank steaks are relatively thin, so this is going to cook pretty quickly and you don’t want it to overcook. Pull the steak when the middle of the steak reaches 120-125°F.


Rest and Enjoy

Let the steak rest for 10-15 minutes, tented, to allow all of the juices to redistribute. Slice and enjoy.

Blackstone Flank Steak FAQ

Can this dish be made in advance?

Nope! Steak is not one of those things that you can make way ahead of time and reheat when you feel like eating it. Are the leftovers delicious? Sure! But not as delicious as it could be if you had eaten it when it was meant to be eaten, right after the rest.

If you want something that’s easy to make ahead, try a Traeger Meatball Sub Casserole (which can be made in the oven), or our Blackstone Griddle Quesadillas.

What’s the best way to store and reheat leftovers?

We toss any leftovers into a freezer baggie and put it in the fridge. These leftovers work great in a steak sandwich, or in our Blackstone Steak and Egg Bagel Sandwich too.
