    Frequently Asked Questions

    What are the best potatoes to use?

    Yukon Gold or Russet is the potato I recommend. The starch in these mixes up so fluffy, whereas red potatoes are waxier, but will work if that is what you have on hand.

    How many people with this feed?

    The recipe on its own feeds 8 to 10. But if you have several starchy side dishes on the table, it can feed even more. Served with corn casserole and dinner rolls, the recipe stretches much further. And you can easily double and even triple the recipe!

    Single Recipe: 8 - 10 people
    Double: 20-25 people
    Triple: 30-40

    Is this a dish I can serve to my Gluten-Free relatives?

    Why yes, it is. When choosing the correct brand of ingredients, this can be a gluten-free side dish for them. All you need to do is use sour cream and bacon pieces that are GF, be sure the spices are all GF, and shred the cheese from a block.

    Variations and Substitutions:

    • Add taco seasoning to the mix and top with jalapenos or green chiles for a Mexican twist.
    • Out of heavy cream, that is alright. You can use whole milk instead.
    • For a bold taste, you can add blue cheese to the cheddar and serve with wings!
    • You can use fresh minced garlic and cream cheese in the mixture for a delicious combination.
    • Don't like green onions or have if you don't have them on hand, substitute parsley or chives (fresh or dried will work).

    Make Ahead, Storage and Reheating Instructions:

    Make Ahead:

    The loaded mashed potato casserole can be made up to 2 days ahead of time.

    • Make and spread into a baking dish.
    • Cover with plastic wrap and foil and place in the refrigerator for up to 2 days.
    • Remove from the refridgerator about 30 minutes before baking. Then remove plastic wrap, cover with foil and bake as directed. Depending on how cold it is when it goes in the oven you may need a few extra minutes of cook time.

    Storage:

    Cover with foil or plastic wrap or place in an air-tight container and store in the refrigerator for 3 to 4 days.

    Freeze:

    For casseroles, Completely cool and then I recommend covering with plastic wrap first, then foil. Then it can be stored in the freezer for up to 4 months.

    If frozen, thaw completely in the fridge overnight. Reheat in the microwave, or remove plastic wrap and then cover with foil and heat in the oven at 350 degrees until warmed through.

    Reheat:

    To reheat individual servings, place desired amount on a microwave-safe dish and reheat. Start with 1 minute and stir. Then add 30-second intervals until heated to your liking.

      We had leftover mashed potatoes so I decided to give this a try. And I am so glad I did! It was amazing! If you didn't think mashed potatoes could get any better, check this out! We love it so much, I think we will be making more mashed potatoes just to have leftovers to make this in the future!

      I just had the best compliment about your potato casserole at the dinner table (of course, I gave you all the credit :D). Super delicious and decadent recipe! You cannot beat a combo of potatoes, bacon and sour cream, right? But with all that cheese and seasoning - it's on a whole new level! The best!
