First, Preheat your oven to 350 degrees Fahrenheit. Spray a large casserole dish with non-stick cooking spray. Steam the cauliflower florets in the microwave for 5 minutes. Drain well.

While the cauliflower is steaming, make the cheese sauce. In a medium saucepan, heat the heavy cream, cream cheese, and butter over low to medium heat until the butter and cream cheese has melted and heated through. Do not boil, if it starts to boil, reduce the heat to low. Whisk in the salt, pepper, turmeric, garlic powder and paprika until combined. Whisk in 2 cups of shredded cheddar cheese, 1 cup at a time, until melted and the sauce is thick and creamy. Remove from heat.

Put the steamed cauliflower into the prepared casserole dish. Pour the cheese sauce over the cauliflower and stir to combine and coat the cauliflower. Sprinkle the remaining 1/2 cup of cheese over the casserole. Feel free to use a whole cup to top the casserole if you want a cheesier top.

Place the casserole into the preheated oven on the center rack and bake at 350 degrees Fahrenheit for about 30 minutes, or until the sauce is bubbly and thickened to your liking. Note: The longer it bakes, the thicker the sauce will become.

Carefully remove the casserole from the oven and allow to cool for 5 - 10 minutes before serving.
