    Looks like another delicious dish, Natasha)
    Question: if i wanna double the recipe, do i use a 9 by 13 baking dish?
    Also, to what step can i make ahead the recipe to minimize time before i can serve? Reply

      November 21, 2018

      Hi Viktoriya, yes I would use a 9×13 baking dish when doubling. To save time, you can make the mashed potatoes a day ahead. I suggest using our creamy mashed potatoes since they don’t firm up when they are chilled and will freshen up very easily. You can also pre-shred your cheese and pre sautee your bacon and just cover and keep all 3 parts separate in the fridge then assemble and bake before serving. If you are starting out with chilled potatoes, you may need a few extra minutes in the oven and mash them up to make them a little creamier before adding to the casserole. Reply

    What size baking dish works for this? I want to use an 8×8 dish but am thinking this recipe might need a 9×13. Help! Reply

      Hi, Jerry! An 8×8 will work. Mine was 9×9 and there was room for more potatoes. I hope you enjoy the recipe. 🙂 Reply
