Prepare cauliflower by cutting it into florets.

In a large saucepan, place a steamer basket over 1 inch of water.

Place the cauliflower florets in the steamer basket.

Bring the water to a boil, then reduce heat to maintain a simmer.

Cover and steam the cauliflower until tender, about 10-12 minutes.

While the cauliflower is steaming, prepare the cheese sauce.

In a small saucepan, mix cornstarch, salt, and white pepper.

Stir in milk and butter until the mixture is smooth.

Bring the mixture to a boil over medium heat, stirring constantly.

Cook and stir until the sauce has thickened, about 2-4 minutes.

Reduce heat to low and stir in the shredded white cheddar cheese until melted and smooth.

Once the cauliflower is tender, drain it well.

Transfer the steamed cauliflower to a serving bowl.

Pour the cheese sauce over the cauliflower.

If desired, sprinkle with paprika for color and flavor.
