Print Recipe Pin Recipe
These mashed potatoes are extra creamy and delicious because they cook in butter and cream instead of water! This side dish is hands off with almost no dishes to clean.

Ingredients
 

  • .8 lb russet potatoes (about 1 large), peeled & cut into 1 inch cubes
  • 1.6 lbs yellow potatoes (about 4 large), peeled & cut into 1 inch cubes
  • 1/2 cup salted butter, sliced into pats
  • 1 1/2 tsp kosher salt
  • 1 tsp Italian seasoning
  • 1 1/2 tsp garlic powder, (sub with 4 cloves minced garlic if desired)
  • 1/2 tsp freshly cracked black pepper
  • 1/2 cup milk (1%, 2%, or whole)
  • 1/3 cup heavy cream
  • 1/4 cup sour cream

Equipment

Instructions
 

  • Preheat a water bath using an immersion circulator to 190 degrees F.
  • Add the potatoes, butter, salt, pepper, garlic powder, and Italian seasoning to a gallon-sized zipper top or chamber vacuum seal bag. Toss to evenly disperse. Add the milk and cream.
  • If using a gallon-sized zipper top bag, use the "arm method" or water displacement method to remove the air from the bag (see tutorials here). Otherwise, remove the air with your chamber vacuum sealer.
  • Place bag in preheated water bath and cook for 2-4 hours. Make sure potatoes stay completely submerged using sous vide magnets or by placing a ceramic plate or bowl on top of the potatoes.
  • After the potatoes are done cooking, transfer the contents of the bag to a bowl. Add the sour cream. Mash using a potato masher to your desired consistency. Taste and add additional salt if desired. Serve.

Notes

You can get the ingredients ready and in the bag up to 3 days in advance of cooking - keep in the refrigerator.
190 degrees F is hot for a sous vide cook - consider placing a trivet under your water bath to protect your countertops.
