Key Takeaways

  • Choose a well-marbled flank steak that is 1 to 1 1/2 inches thick
  • Keep the seasoning simple with salt, pepper, and garlic powder
  • Preheat the wood pellet grill to around 450°F for a nice sear
  • Let the grilled flank steak rest for 5-10 minutes before slicing

Selecting the Perfect Flank Steak

You’ll want to make sure you choose a flank steak that is well-marbled and about 1 to 1 1/2 inches thick for the best grilling results. The marbling ensures that the steak will be juicy and flavorful, while the thickness allows for even cooking.

When it comes to seasoning, I recommend keeping it simple to let the natural flavors of the meat shine through. A combination of salt, pepper, and garlic powder works beautifully.

As for grilling temperature and time, aim for a medium-high heat of around 400°F. Cook the flank steak for about 4-5 minutes per side for a medium-rare doneness. This will give you a nicely seared exterior and a tender, pink center.

Now, let’s move on to preparing the wood pellet grill for the perfect grilling experience.

Preparing the Wood Pellet Grill

To get started, it’s important to properly set up your wood pellet grill before grilling the flank steak. First, make sure your grill is clean and free of any debris from previous uses. This will ensure that your steak cooks evenly and doesn’t pick up any unwanted flavors.

Next, adjust the temperature settings on your grill. For a flank steak, you’ll want to preheat your grill to a medium-high heat of around 400°F. This will give you a nice sear on the outside while keeping the inside juicy and tender.

Once your grill is clean and preheated, you’re ready to move on to seasoning and marinating the flank steak.

Transition: Now that the grill is set up, it’s time to move on to seasoning and marinating the flank steak.

Seasoning and Marinating the Flank Steak

Now that the setup is complete, it’s time to add flavor by seasoning and marinating the flank steak.

To enhance the taste and tenderness of the steak, follow these steps:

  • Start by generously seasoning both sides of the flank steak with salt and pepper. This will help bring out the natural flavors of the meat.

  • Next, prepare a marinade using your favorite ingredients such as soy sauce, garlic, Worcestershire sauce, and olive oil. This will infuse the steak with delicious flavors and help tenderize the meat.

  • Place the seasoned flank steak in a ziplock bag or a shallow dish and pour the marinade over it. Make sure the steak is fully coated and allow it to marinate in the refrigerator for at least 2 hours, or preferably overnight. This will allow the flavors to penetrate the meat.

  • Before grilling, remove the flank steak from the marinade and let it come to room temperature. This will ensure even cooking and prevent the steak from drying out.

With the flank steak well-seasoned and marinated, it’s time to move on to the next section about grilling techniques for flank steak.

Grilling Techniques for Flank Steak

Get ready to cook the marinated flank steak using high heat and a direct cooking method, which will give it a deliciously charred exterior and a juicy interior.

Before you start grilling, it’s important to understand the cooking temperatures and techniques that will ensure a perfectly cooked steak. Preheat your wood pellet grill to around 450°F to achieve a nice sear and grill marks. Place the marinated flank steak directly on the hot grates and let it cook for about 4-5 minutes per side for medium-rare, or adjust the time according to your desired doneness. Flip the steak only once to get those beautiful grill marks.

Once the steak is cooked to your liking, remove it from the grill and let it rest for a few minutes before slicing. This will allow the juices to redistribute, resulting in a tender and flavorful steak.

Now, let’s move on to the next section where we’ll discuss how to properly serve and enjoy your grilled flank steak.

Resting and Serving the Grilled Flank Steak

Once the grilled flank steak is cooked to your desired doneness, it’s time to let it rest and then serve it up for a delicious meal. Resting is a crucial step that allows the juices to redistribute, resulting in a more flavorful and tender steak.

I recommend letting the steak rest for about 5-10 minutes before slicing it. During this rest time, cover the steak loosely with foil to keep it warm.

When it comes to slicing the flank steak, it’s important to do it against the grain. This means cutting across the muscle fibers to ensure maximum tenderness. Use a sharp knife and make thin slices, about 1/4 inch thick.
