Prep Steak: Cut 2 pounds ribeye steak into 1-inch cubes and remove any excess fat. Season with kosher salt and ground black pepper and set aside.
Make Cowboy Butter: In a small bowl, add 4 tablespoons butter (softened), 1 teaspoon garlic, 1 teaspoon dijon mustard, ½ teaspoon lemon juice, ¼ teaspoon paprika, ¼ teaspoon dried thyme, ¼ teaspoon dried parsley, and a pinch kosher salt. Mix to combine and set aside.
Prep Blackstone: Bring the flat top griddle to a high heat and bring everything out to the cook top. The cook time will go VERY fast, so it is really important to have everything ready to go.
Cook Steak: Once hot, drizzle 1 tablespoon extra virgin olive oil on the cook top and add the steak chunks in a spaced out single layer to sear for 1 minute (set a stopwatch). Use a large spatula to toss the steak, cook 1 minute. Add cowboy butter and continue tossing the steak until their internal temperature reaches 125℉ (medium-rare). This should take about 4 minutes total.
Serve: Let rest for 5 minutes and then enjoy!
Notes
Dairy-Free: use a plant-based butter.
Garlic Herb Butter: highly recommend the included cowboy butter, but we also have a traditional garlic herb butter that would also be delicious!
Steak: this recipe was tested with ribeye steak (because it's my favorite) but feel free to use your favorite cut of steak.
Storage: leftovers can be stored in an airtight container in the fridge for 4-5 days.
