What toppings are added to our chili?

The toppings that are traditionally added to Texas Roadhouse chili include red onions and cheddar cheese. These toppings enhance the flavor profile of the chili by adding a crunch and sharpness from the onions, along with the rich, creamy texture and taste provided by the cheddar cheese. This combination not only complements the hearty and spicy nature of the chili but also adds visual appeal and a satisfying contrast of textures.

In the context of the other options, while jalapenos and sour cream can be common chili toppings in some other recipes, they are not the standard for Texas Roadhouse chili. Green onions and mozzarella also do not align with the established toppings, as green onions typically lend more of a freshness and mozzarella does not provide the same depth of flavor expected from cheddar in this dish. Similarly, while cheddar cheese is indeed a correct topping, the addition of bacon would lead to a different flavor profile not typical for the Texas Roadhouse chili.
