Recipe Notes

    • You can experiment with your favorite cheese such as a mild cheddar or add a combination of difference cheese blends such as cheddar, swiss and colby.
    • If your mashed potatoes are well seasoned then you may want to either cut back or omit the salt and pepper.  You can also use other seasonings such as onion powder and garlic powder.
    • You may want to use less or more butter for cooking the onion depending on the amount that you use in your mashed potatoes.  Some recipes call for cooking the onions in 1/2 cup of butter but if you use a lot of butter in your mashed potatoes you wont need as much for the onions.
    • Instant potatoes are not recommended for this recipe but you can save time by using refrigerated mashed potatoes such as Bob Evans brand. You should be able to find these and other brands in the refrigerated section of your supermarket.

Topping Ideas:
For added flavor, top with bacon bits and sour cream.
