Step 1

Preheat the oven to 275 F. Pat the steaks completely dry. Season both sides with salt and pepper. Press the seasoning into the steaks, and place onto a baking sheet fitted with a wire rack.

Step 2

Place the steaks on the middle rack of the oven, and bake until the internal temperature is 120F or 125F, about 30 minutes. Remove from the oven and tent with foil.

Step 3

While the steaks are tenting in foil, heat a cast iron skillet over medium heat until very hot. Add the oil and butter, and allow the butter to melt. Add the garlic and thyme.

Step 4

Once the butter has melted, and the oil is sizzling, add the steaks. Sear for 1 minute on each side, just enough to sear a crust onto the exterior. On the second side, baste the butter over the steaks using a spoon.

Step 5

Remove from the skillet, and serve steaks immediately.
