I rarely measure with this dish so I am linking a recipe. I don't use Thyme and many times I just use milk, flour, butter,Velveeta, tbsp. of parmesan and pepper it well for the sauce and I like the cauliflower NOT crisp and NOT mushy.
Here is the recipe.
Cheese Sauce Over Cauliflower Recipe | Taste of Home
People rave about expensive steak, but lovely fresh vegetables and fruits occupying the other side of the plate can be so yummy. I love fresh cauliflower with cheese sauce with a lovely meat loaf and a tossed salad with a dressing that has a hint of sweetness.
