What ingredient makes Risotto creamy?

The ingredient that makes Risotto creamy is primarily cheese. When risotto is cooked, arborio rice releases starch, which contributes to the dish's creamy texture. As the risotto is stirred and gradually mixed with broth, the starches thicken the dish, creating a richness. Cheese is usually added at the end, which enhances this creaminess by melting into the dish.

While broth is crucial in the cooking process, it acts more as the liquid that helps cook the rice rather than directly contributing to the creamy texture. Butter can add richness and flavor but doesn't create the creamy texture alone. Milk might make a dish creamier in some contexts, but it is not traditionally used in risotto. Therefore, cheese is key to achieving that desired creamy consistency in risotto.
