Preheat the oven to 325 degrees. Season the rabbit with salt and pepper. In a large oven-safe skillet, heat 2 Tbsp. olive oil over medium-high heat. Add the rabbit, in batches to avoid crowding the pan, and sear on both sides until brown and crusty. Add 1 Tbsp. oil for the second batch, if needed, and reduce the heat if it starts to burn. Reserve the browned rabbit in a bowl.
