Ingredients
 

  • 5 pounds Russet or Gold potatoes peeled and cut into chunks of even size (about 2 inches)
  • 1 cup water or low sodium chicken broth
  • 1 ½ tsp salt
  • ¾ cup (about 1 1/2 sticks or 12 tbsp) butter, cubed
  • 8 oz package of cream cheese, softened
  • 1 cup half and half or whole milk, heated
  • salt and pepper, to taste or as needed
  • ¼ cup up to 1/2 cup butter, cubed for serving
  • fresh chives, diced and use for garnish

Instructions
 

  • Pour in 1 cup water and add 1 1/2 tsp salt to the instant pot. Mix. Place a trivet into the instant pot bowl.
  • Place the peeled and cut up potatoes over the trivet. Cover with the lid and set the valve to ‘sealing’ position. Cook on manual high pressure for 12 minutes. When done, do a quick release.  Once pressure has fully released, remove the lid then remove the trivet using a large fork or tongs. Don’t drain the water.
  • Work on the potatoes (which should be quite tender at this point) with a masher.
  • Pour over the heated or warmed-up light cream (half and half) or milk and continue to mix and mash. Adjust the amount of liquid to your desired consistency.
  • Add in the cubed butter and softened cream cheese and mix just until blended.
  • Use an electric hand mixer to achieve a smoother and lump-free consistency. Season to taste with more salt and a little pepper, if desired.
  • Serve right away if that's your plan. If you wish to make this ahead, transfer the mashed potatoes to a baking dish. A 9x13 pan should work best. Allow to cool completely then cover and chill. This can be made 1-2 days ahead.
  • Make sure to take the pan out of the fridge for a few hours so it reaches room temperature. I have used the slow cooker to warm the mashed potatoes up too, especially if the oven is occupied.
  • If not using the slow cooker, simply cover the dish and bake potatoes at a preheated 350 F oven for 50-60 minutes until heated through.
  • Before serving, cube the remaining butter (use between 1/4 to 1/2 cup butter, adjusted to your taste) and lay the slices on top of the mashed potatoes. The heat of mashed potatoes would melt the butter. Sprinkle with finely diced chives for garnish, if desired.

Notes

TIPS & TRICKS
If you wish to just make this and serve it the same day and use a simpler recipe - here's how I do it.  
After the potatoes have been cooked in the instant pot and mashed initially with a masher - add the following: 1 cup heated half and half or whole milk, 12 tablespoons butter, salt, and white pepper as needed to taste. Use a hand mixer to make the mashed potatoes smooth and lump-free. Enjoy.
