Preheat oven to 275 degrees F. Place a wire cooling rack onto a baking sheet, then place the uncooked ribeye steak onto the wire rack. Season both side of the ribeye steak with the Santa Maria seasoning.
Place the steak into the oven and bake for 15 minutes or until the internal temperature reaches about 90 degrees F. At the same time, place a cast-iron skillet into the oven to let it warm as the steak cooks.When the steak has reached 90 degrees F, remove from the oven. Carefully remove the cast iron skillet (it will be hot) and place onto a burner on the stove. Add 1 Tbsp. of avocado oil to the cast iron skillet and heat over high heat until it begins to smoke.Next, carefully place the ribeye steak into the cast iron skillet and sear for two minutes on one side, then flip and sear for another 1-2 minutes or until the internal temperature reaches your desired level of doneness.
Carefully remove from the cast iron skillet and let rest on a plate for 10 minutes. Top with 1 Tbsp. of unsalted butter and fresh rosemary and allow it to melt as it rests.
Santa Maria seasoning is a simple steak seasoning made with a mixture of salt and pepper, granulated honey or sugar, granulated garlic, and onion powder. It's featured in our Brazilian churrascaria-style Picanha Steak Recipe, too! We think it is the best steak seasoning.
Avocado oil is available at most grocery stores and can be found alongside other oils. There is often an avocado on the label.
