How to Make It

Step 1

Cut cauliflower into florets (about 3 cups). Cook in boiling salted water to cover 10 to 12 minutes or until tender; drain and set aside.

Step 2

Melt 4 tablespoons butter in a medium saucepan over medium-high heat. Whisk in flour until smooth. Gradually add milk, whisking constantly, until mixture begins to thicken. Add cheese and sour cream, stirring until cheese melts. (Do not boil.)

Step 3

Stir cauliflower, ham, and mushrooms into cheese sauce; pour into a 2-quart baking dish. Sprinkle breadcrumbs evenly over casserole. Cut 1 tablespoon butter into pieces, and sprinkle evenly over breadcrumbs.

Step 4

Bake casserole, uncovered, at 350° for 45 minutes.
