What does "smother" refer to in a meal at Texas Roadhouse?

In the context of Texas Roadhouse, "smother" specifically refers to the combination of sautéed mushrooms and onions topped with cheese that is added to a meal. This preparation is a signature part of the offering, particularly for items like steaks, providing a rich flavor and texture contrast that enhances the dining experience.

The concept of smothering a dish with these ingredients signifies a generous addition, which is popular among diners looking for something indulgent. It elevates the basic meal by adding layers of flavor, making it appealing to guests who enjoy dishes that are hearty and fulfilling.

The other options relate to different culinary techniques or garnishes that do not align with the specific Texas Roadhouse terminology for smothering. For instance, butter and garlic sauce might enhance a dish but is not associated with the "smother" terminology used in their menu. Extra spices and sauces or garnishing with herbs and vegetables, while relevant in broader culinary practices, do not match the specific combination of ingredients that define a "smothered" meal at Texas Roadhouse.
