If your steak is thicker than 1 1/2 inches, preheat the oven to 400 degrees.
Heat a medium stainless steel pan on the stove over medium high heat. While heating, season all sides of the steaks with Overachiever seasoning.
Once the pan is heated, add 2-3 Tbsp avocado oil and immediately add the steaks, ensuring they are not touching one another. Sear on the first side for 3-4 minutes, until a crust begins to form. Flip the steak.
Add the sage leaves and gently baste some of the oil over the steaks.
IF STEAKS ARE THICK: place the pan with the steaks in the preheated oven, checking the temperature every 4-5 minutes until you reach 7-10 degrees below desired temperature. Remove from the oven and put back on medium high heat. IF STEAKS ARE THIN: sear on both sides and cook in the pan until 7-10 degrees below desired temperature.
Add the ghee or duck fat to the pan, allow it to melt, and then begin basting the steaks for 2-3 minutes. Remove from the heat and place on a plate to rest. Pour the hot butter over and allow to cool for 10-20 minutes, depending on how thick the steak is. Serve warm with your favorite sides.
