Preheat the oven to 425℉.

Place the cauliflower on a baking sheet and drizzle with olive oil. Season the cauliflower with 1 teaspoon salt, pepper, thyme, and paprika onto a baking sheet. Use your hands to massage all of the seasonings into the cauliflower until the cauliflower is coated. Place the cauliflower in the oven and bake for 15 minutes. Set aside.

Next, make the cheese sauce. Add the heavy cream to a saucepan and heat over low/medium heat. Cook for 2 minutes stirring consistently until simmering (not boiling) and then add the shredded cheddar cheese and stir. Heat until the cheese is melted.

Remove from the heat and add the roasted cauliflower and remaining salt. Mix to combine everything together.

Serve immediately.
