Ok guys, one big secret to Texas Roadhouse's sirloin is a bold seasoning blend and a solid sear on high heat.Coarse salt, black pepper, and garlic powder do wonders, but the real trick is a touch of brown sugar to help with caramelization.It goes without saying to the steak rest at room temperature for 30 minutes before cooking—this step helps it cook more evenly.A light brush of melted butter at the end makes each bite even better, especially with a little fresh thyme mixed in.Once it’s off the heat, a quick butter baste with a little garlic makes all the difference in bringing out that steakhouse-style finish.
