Potato and Cauliflower Casserole

Step 1
Preheat the oven to 350 degrees F (175 degrees C). Lightly grease a medium casserole dish.

Step 2
In a pot with enough water to cover, boil potatoes for 10 minutes, or until tender but still firm. Drain, and set aside.

Step 3
In a pot, place cauliflower in a steamer basket over boiling water. Steam 5 minutes, until tender but still firm. Set aside.

Step 4
Melt butter in a saucepan over medium heat, and whisk in flour. Gradually stir in heavy cream until thickened. Remove from heat, and mix in 1/2 cup Swiss cheese until melted. Season with salt and pepper.

Step 5
Arrange potatoes and cauliflower in the prepared casserole dish. Pour cream sauce over potatoes and cauliflower, and sprinkle with remaining Swiss cheese.

Step 6
Bake 20 minutes in the preheated oven, or until bubbly and lightly browned.
