How to make a Grilled Steak with Chimichurri Butter

Make the Chimichurri Butter

Start off by hand chopping the parsley, cilantro and garlic. This will give the chimichurri a great texture when eating it.

I typically avoid using a food processor anytime I make chimichurri because it turns it into a paste. Combine them in a bowl with 2 tbsp olive oil, 1 tbsp red wine vinegar, ½ tsp salt, ½ tsp black pepper, ½ tsp crushed red pepper flakes and 1 stick of softened butter.

Mix all of the ingredients thoroughly, then place in some plastic wrap or parchment paper. Roll it into a stick of butter then place it in the fridge for 30 minutes.

Cooking the steak

Get your grill fired up and get it ready for indirect cooking. The steak is going to be smoked at 225°F so that the internal temperature comes up slowly and evenly.

I like to use a stronger wood flavor like hickory or oak wood chunks, but pecan is also another great option as well.

Take the steak out of the fridge about 30 minutes ahead of time allowing it to come up to room temperature. I picked up this massive tomahawk steak from my local Hy-Vee.

I love how thick tomahawks are which helps prevent the steak from being overcooked. You can use any other sort of cut that you like such as any ribeye steaks, NY strip, skirt steak, chuck eye or flat iron.

Generously season all sides of the tomahawk steak with SPG (salt, pepper, garlic powder).

Place the steak indirectly on the grill at 225° F for 30 minutes. I used a Kamado Joe for this cook which is a ceramic style cooker that works great for smoking then reverse searing a steak.

Once the internal temperature of the steak reaches 110°F, remove it from the grill and increase the temperature to high heat. 

Sear the steak over direct heat for 2-3 minutes on both sides.

Once you have some good crust, move the steak back indirectly of heat. Add two slices of the butter on top of the steak and let it finish cooking.

Remove it from the grill once it reaches an internal temp of 127° F. Let it rest for 15 minutes then slice the steak against the grain.
