Step 1

Preheat oven to 450°F. Spray three 12-ounce baking dishes (or a 1 quart baking dish) with non-stick spray.

Step 2

In a large pot, cover potatoes with cold salted water. Bring to a boil. Once boiling, add cauliflower and cook about 8 minutes or until potatoes are just cooked through and cauliflower is tender. Drain in colander and let sit at least five minutes.

Step 3

Divide the cauliflower/potatoes between the three prepared baking dishes. Sprinkle with pepper and thyme. Top with cheddar (divide evenly between three dishes). Pour milk over each (divide evenly between three dishes) and dot with butter. Bake for 10-15 minutes or until cheese is golden brown and bubbling.
