This is a great side dish with tons of flavor and is easy to prepare. The smell is fantastic! (No crust to make.) Great served with chicken on the spit and a tossed green salad. Sliced potatoes and onions cooked in sour cream and cheese of your choice. I hope you try this side dish! Enjoy!

    Step 2
    Spray a 10-inch glass pie dish with Pam. Scatter 2 tsp of garlic on the bottom of the Pam-sprayed pie dish.
  • Put half of the sliced potatoes on top of the garlic, overlapping the slices. Add half of the onion slices.
    Step 3
    Put half of the sliced potatoes on top of the garlic, overlapping the slices. Add half of the onion slices. Add salt and pepper (go easy on the pepper).

    Step 9
    Cook's Tip: A word about cheese. I have used Colby Jack cheese, Fontina, Gruyere cheese, and cheddar, but I like Fontina and Colby Jack cheese the best. For the milk mixture, I use a combination of sour cream, heavy cream, and 2% milk which is what I had on hand. You can use all milk, or all cream, or mix it up. Use what you like. Experiment to your heart's content. This is a fun recipe for that!
