How to Make Twice Baked Potatoes in the Pressure Cooker:

  • Step 1 – First scrub the potatoes to clean them since you leave the potato skins on for this recipe. 
  • Step 2 – Once they are dry, cut your potatoes into chunks and don’t forget to leave the skin on.
  • Step 4 – Add 1 cup of water, 1 stick of the butter, and salt and pepper.
  • Step 4 – Then place the lid on top and make sure your nob is set to sealing position on the lid.
  • Step 5 – After this cook on high pressure under the manual setting for 6 minutes. You are free to walk away and wait until the instant pot beeps.
  • Step 6 – After this pressure cooking time, do the quick release to relieve the pressure from the electric pressure cooker. We recommend the quick release instead of natural release.
  • Step 7 – Then add the remaining butter and the milk directly into the insert of your instant pot.  Mix well with an electric hand mixer right in the instant pot or mash with a hand masher.
  • Step 8 – After these ingredients are combined, add in the sour cream, ranch mix, and mix well. Then fold in the shredded cheese and green onions.
  • Step 9 – Next place the potato mixture in a casserole dish or your favorite baking dish.  Then top with the remaining cheese, chives, bacon.
  • Step 10 – Baked in a 350 degree preheated oven for 15 minutes – 20 minutes until the cheese is melted on top.
  • Step 11 – Serve and enjoy.

  2. Carrie Barnard says:

    Yes you can.

  3. Elaine says:

    I’ve made this a few times and continue to get the burn notice. Do you suggest adding more water?

  4. Lorraine says:

    5 stars
    Can you just use the leftover mashed potatoes and add the other ingredients and bake it in the oven?

  5. Carrie says:

    Yes, that would work great!

  6. Jan says:

    Can this be made the day before, refrigerated and then baked?


    5 stars
    great to feed a large group.

  8. Melissa Prigel says:

    Make this using leftover mashed potatoes all the time & nobody knows it’s leftovers 😉

  9. Gina says:

    It says 6 services but how much is actually in one serving? Please and thank you!

  10. Karli says:

    Is it possible to half this recipe? I know you usually need 1 cup of water in your instant pot, so could I just keep that and half everything else?

  11. Carrie says:

    I used 1 packet for this recipe. Thank you.

  12. Max says:

    How much ranch mix?

  13. Carrie says:

    Donna – Yes, I think that would taste great. Thank you.

  14. Donna says:

    Can I use ranch dip package instead of dressing

  15. Carrie says:

    I haven’t tried that yet but I think that would work.

  16. Dale says:

    My instant pot has s cake feature; so could I also bake this in the instant pot?

  17. Carrie says:

    Sandra – I would make the potatoes like how you normal making mashed potatoes and then construct the casserole from there. Thanks and good luck!

  18. Sandra says:

    5 stars
    What if I don’t have a pressure cooker.

  19. Carrie says:

    Yes, I think you could use the crock pot for the last step instead of the oven to keep them warm. Thanks.

  20. Clara says:

    Can do this recipe in a crockpot instead of the oven? Looking for something to take to potluck ?

  21. Carrie says:

    Laure – Yes, definitely!

  22. laurie says:

    dont have an instapot can I just boil the potatoes and drain and continue like making regular mashed potatoes

  23. Brooke says:

    5 stars
    In the past month I’ve made this recipe 3 times. It was very good the first time I made it for Thanksgiving and people really liked it. However, the 2nd time I added a brick of cream cheese at the same time as the sour cream and it made it a homerun! I HIGHLY recommend adding cream cheese. It elevates it to the next level!

  24. Carrie says:

    Just about any kind will work well.

  25. Anna says:

    What kind of potatoes would you recommend to use?

  26. Doug says:

    Can you cook this in a regular old style pressure cooker?

  27. Jenn says:

    Super delicious! A total hit at the party. Followed recipe to the letter. I wondered about draining off the water before mashing, but since the stick of butter was in there, decided not to drain. Super creamy and the ranch flavor really added something unexpected.

  28. Kathi says:

    5 stars
    I have made a recipe similar to these for years. However, I would NOT recommend that you mash the potatoes in your instant pot pot or it may void the warranty and damage the non-stick interior. Other than that – they are really great potatoes for a pot-luck too.
