    I love mashed potato casserole, but the version I make has French fried onions. And no bacon. WHY HAVEN'T I PUT BACON IN IT???? This looks delicious. I will be making it!

  2. terrie

    Going to make these for Easter dinner can they be made the day before?

    1. Randa

      Terrie & Lisa~~I see no reason this cannot be made 1-2 days before serving date. I make my twice baked potatoes...almost same ingredients...a few days ahead & they turn out great. Actually they are better than served the day they are made as the few days in the fridge allow the ingredients to 'marry'. This casserole style would be much easier than fussing with the skins etc.

    2. Linda


      To reheat, I wouldn't top with cheese and bacon before refrigerating. Bring to room temp before baking ( take out at least 1 hr before baking) Top with cheese and bacon, Bake @ 350° for 25 to 35 min til hot ... save extra bacon in zip lock bag and extra grated cheese the same.

  3. lisa

    Can you make this early and reheat

  4. mary

    Chicken Bouillon has sooooo much sodium....is there something else I can use? Bacon also is high in sodium....my hubby just got out of cardiac intensive care.

    1. gretchen

      maybe cook potatoes in low sodium broth vs water and use low sodium turkey bacon

  5. Natalia

    Made today and it's delicious!

  6. Elena Sifuentes

    Sounds delicious, I would make one change though, I would use buttermilk instead of regular milk it gives it that extra tang.

  7. Marilyn

    Why don't you say how many the recipe will feed? I'm talking about the loaded mashed potato recipe.

  8. Ethel

    Loves your recipes

  9. Darlene

    Oh my gosh. These sound fantastic I do love potatoes! I'll be making these soon.

  10. Debra

    Looks fantastic! Do you think this could work with boxed mashed potatoes? (Don't shoot me! ;) ) I'm horrible at cooking potatoes and would still love to try this.

  11. Janice Bsrtley

    This looks so good and want to make this for Thanksgiving.

  12. Dania

    How many servings does this recipe yield?

    1. Winesnob

      I plan to make these for Christmas. I too was looking for how many servings it made. I weighed 4lbs of potatoes and its about 6 baking potatoes. I would say it yields about 10-12 servings.

  13. Cait

    How many people does this feed???

  14. Christy


    My mom made this 40 years ago for reunions, pitchins, funeral casseroles, etc. She didn't use mashed potatoes though, she scrubbed the potatoes, cut off yucky parts, then cubed and boiled them. Everything else is the same (she probably added more cheese though, lol). Always the first pans emptied!

  15. Nils


    Great recipe. Yummy! I recomend to try this out.

  16. Joan P

    Looks delish!!! I can't wait to try this!

  17. stacey


    omg made this tonight it is so delicious you all gotta try it.

  18. Marla


    For those wondering about amount of servings, I would guess 9-12 servings. It fills a 9x13 pan so it should serve at least that many.

  19. Kaitlin

    Can the chicken boullion powder be thrown out with no worries? Or is there a vegetarian friendly replacement option?

  20. Karen Allen

    I made this for a deck party last night, and it was a BIG HIT! Thank you so much - what a wonderful idea! My husband is a little ticked that there is no leftovers ;)

  21. toni


    I found your recipe on pinterest and loved it! I made a couple of adjustments just because I did not have everything. I left out the garlic salt and garlic powder. I was out of sour cream, so I substituted with mayonnaise. I forgot to buy Parmesan cheese, so I used the powdered stuff. I put most of the green onions into the mixture to be baked as well since I think they taste better cooked. I made sure to leave some leftover green onions for toppings. I ended up making this late in the afternoon so I would only have to reheat it for dinner. I left steps 7 and 8 for when it was time for dinner. Everything was easy to follow and it tasted great!

    1. Susan Green

      It states to put in a 9x13 pan. If you have big eaters it would feed 4-6 people. If lighter eaters or where there is a lot of food such as Thanksgiving it would feed 10-12

  22. Jo

    This was fantastic, it's a keeper

  23. Brea

    If I half this recipe, how long should I bake?

  24. Amanda

    This looks so good! This might just have to be the dish i bring to Thanksgiving this year! Thank you so much for posting!

  25. Tammi @ Momma's Meals

    We enjoyed this very much last night as a part of my daughters birthday dinner celebration. At first I was thinking, wow this is a lot of work. Then I ate it and thought it was well worth the work! :)

  26. Nolanda


    Yum yum yum I have made this a few times an every time it's eaten right up with no left overs. Would highly recommend this to anyone with the love a fantastic Potato dish :)

  27. Myrna Barager


    This was delicious and made lots. I didn't have bouillon. Used evaporated milk and Italian variety shredded cheese (Mozzarella, Provolone and Parmesan).

  28. Dyan

    Can this be prepared and then frozen, for later time,thenbake, top off with cheese, bacon, scallions?

  29. Beatrice


    OMG The Best Recipe Ever and Easy. My Family Loved it!!!

  30. Chelsea

    I have been making these all the time! My husband is obsessed with them! I tend to add extras to the recipe... the bacon grease and some cream cheese... extra bad Texas style hehe. Love the recipe! Thank you!

  31. Jane

    Can I freeze this recipe before baking?

  32. LAURIE

  34. Stephanie

    How many does this recipe serve

  35. Carolyn

    I made this for Sunday dinner and my grand babies went crazy they wanted me to make it the next Sunday it was delicious

  36. sonal

    can i use 6% blankan yogurt instead of sour cream?

  37. Wynn

    To make day ahead, do you bake it and then reheat? Or get it ready, refrigerate and bake as directed next day?

  38. Gayle

    Could you use the frozen potatoes instead of boiling them? Thanks

  39. Janice Hartl

    This was so good and so easy.

  40. Jean


    Looks real good. Am going to give it a try but instead of bacon will try ground beef.

  41. Gayatri Mantra


    I always make this for one of the holidays. My family loves it.

  42. Maddy


    how many people does this recipe serve ??

  43. Carey


    DE. LI. CIOUS. There is nothing else to say.

  44. Debra Johnson

    You don't say how many it serves... I need a potluck dish... can you tell me quick so I can make one or two pans tonight?

  45. Tabatha Tovar


    Omg!! This so yummy!!! My family loves it, i will definitely be making this over and over again..

  46. Megan


    Divine! I love potatoes, but these are my new favorite.

    I did make one small change and used a bag of prepared bacon bits (not the dry crunchy ones, but the packaged real cooked bacon pieces) in place of real bacon. It worked amazingly well and I didn't have to fend off my husband and kids while trying to prep bacon for the recipe. They get one smell of bacon cooking and resort to all means of begging and scheming to eat it before it ever makes its way into whatever dish I have in mind!

  47. Cherie Chilvers


    I am making this tomorrow for our Bible Study Class for our Christmas Party.

  48. Cherie Chilvers

    Made this recipe yesterday, Dec. 2nd, wow was it a hit and not a drop left over. great recipe!!!

  49. Tomika

    These are amazing I make for special occasion people can’t get enough of them yum

  50. Carol

    These look and sound delicious. I am going to make them too accompany our ham for Christmas this year. I thought they would be a nice change from scalloped potatoes. I'll come back and let you know how the family likes them.

  51. Diane

    Sounds good
    If using leftover mashed potatoes approximately how much would you need?

  52. Deanna

    Looks delicious!!! I will be making this for Easter.. my family is a huge homemade mashed potatoes fan! I normally skin the potatoes and then boil them... do you keep the skin on?

  53. Dana O

    Hello Nikki, haven't made this recipe yet but def planning on it for this Easter! For some reason my regular mash potatoes never seem to taste good to me so I thought a casserole type potato would be great to do. I'll send a pic when I make them.

  54. Shona


    Made this recipe for Easter as I had about 23 people. Wow! raving reviews. I was even asked for the recipe. Thank you for such a great recipe. I will make this again, and again.

  55. Nicolee


    I made this today and it was super good! I made only half the recipe since there is only 2 of us and we still have some left over. This was an easy and oh so good recipe1 Thank you so much!

  56. Betty L


    I will be making this recipe today for my husband. He loves Fried Cabbage. This will be the first time with Sausage normally I use Pork Chops with apple and lots of black pepper and serve with Corn Bread backed in cast iron skillet. Delicious for sure. First time visiting your blog. Thank you for sharing.
    Betty L. ( tiny town NE Arkansas)

  57. Jessica L

    Does it have to be russet potatoes or can you use any kind?

  58. Terri

    Does anyone know if you can freeze this once prepared?

  59. Jackson Landry

    I don’t cook, I literally use my oven to store books, but I’m going to attempt this for an Easter potluck. Wish me luck ; )

  60. Jenny Sawyer


    These are so good! I’ve made them several times now and they’ve become a favorite in my family. They love them! My son calls them “miracle potatoes!” ?

  61. Lynette


    This is our new favorite way to eat potatoes. I had a recipe with cream cheese in it that is delicious but since I have made this recipe we have not done the other one. The bacon and cheddar just add the extra goodness!
