The great thing about this recipe is that it’s very versatile!  You can use leftover potatoes or even make Crock Pot Baked Potatoes. If you’re in a rush you can also boil the potatoes with a couple of cloves of garlic. So easy!

    1. I have only tried the recipe as written Raeona, but you could possibly try substituting for Greek yogurt.

  1. When making ahead of time do you assemble then bake when ready to serve or bake ahead of time and reheat when needed?
    Thank you!

    1. I prepare ahead and don’t bake until just before serving. You might need to add a few minutes of cooking time if it’s cold from the fridge.

  2. Hi Cassandra,
    This recipe is just what I’m looking for to serve a crowd of sixteen. Can I make it and freeze it before cooking (or cook it first) ahead of time? I’m not sure do to the sour cream and cream cheese. Looking forward to trying this it sounds delicious!

    1. Definitely, Kelley! You can freeze this and bake it at approximately 350°F for about 45-55 minutes. Just mix the sour cream and cream cheese in as directed in the recipe :)

  3. When prepping this the day before, what time and temp would I heat this up at after being in the fridge? I’m assuming I would wait to bake it after mixing everything together, then put the toppings on right before putting it in the oven the next day?

    1. Hi Cassandra, I would let it sit at room temperature while your oven preheats, add toppings, and then bake following the recipe instructions. It may need an extra few minutes after being in the fridge but not too much if any.

    1. Hi Angel, we stir the cheese into the mashed potatoes in Step 5 with the remaining ingredients. You do want to reserve the ½ cup of cheese listed in the topping section for topping the potatoes afterwards.

  4. So good!! Everyone loved it in our house. Used turkey bacon cause it’s all we had. Will definitely be in regular rotation.5 stars

  5. I love that you have a nutritional list at the end of your recipes. My concern is I either can’t find it or there is no serving size. As long as I am sending this I am also adding that I use and like alot of your recipes.

    1. Hi Nadine, we peel about ⅔ of the skin off the potatoes before baking. You can peel all the skin off if you prefer.

  6. i always get your recipe from a friend,so I thought it was time to follow you, I don’t want to miss a day

    1. Welcome Pam! To receive emails with new recipes, you can click here to sign up to receive emails. Look forward to sending you recipes!

      1. I haven’t tried but I think that would work really well! We would love to hear how it turns out for you Barbb.

    1. I don’t see why not Amy! The premade potatoes likely already have butter and sour cream, so please take a look at the ingredients to see what you need to add. Enjoy! Let us know if you try it!
