Wash and cut cauliflower into small florets. Place on a sprayed baking sheet. Generously spray the cauliflower florets then roast for 15 -20 minutes at 450F. Broil for a few minutes if needed.
In a large sauce pan melt the butter, then add flour and whisk until combined.
Pour in the milk as you whisk over medium high heat. Add in the salt and pepper.
Lower the heat to low then add in the cheese is melted and mixture has thickened.
Gently fold in the roasted cauliflower until they are all coated with the cheese sauce. Enjoy warm
You can also air fry your cauliflower florets at 400F for 35-40 minutes or until golden brown. Be sure to use heavy cream if you are making the low carb version! You can omit the flour since heavy cream is thick enough and will thicken as you simmer with the cheese.
