Ingredients

  • 1.5 lb baby gold potatoes
  • 1 lb cauliflower florets (~1 small head)
  • 2 C broth of choice, divided (¾ C reserved)
  • 4-5 C water
  • 1 tablespoon salted butter + more for serving
  • ½ C sour cream
  • ¼ teaspoon salt + add'l salt & pepper to taste
  • ¼ C chopped chives
  • optional: other finely chopped herbs like parsley, rosemary, and/or thyme

Instructions

  • Place potatoes and cauliflower in a large saucepan with 1 + ¼ cup broth and enough water to just cover the vegetables. Boil until potatoes are fork tender (~15-20 minutes)
  • Reserve ½ cup of the cooking liquid and set aside. Drain the remaining liquid
  • In the same pan, mash the cooked potatoes and cauliflower with ¾ cup broth, butter, and sour cream until desired consistency is reached. Add additional reserved liquid if needed. Stir in chives, salt, and pepper.*
  • Serve with additional butter, gravy, or your favorite mashed potato toppings and enjoy!

Notes

Recipe Variations and Substitutions
  • Use plain Greek yogurt instead of sour cream. If desired, you can use plain Greek yogurt to add additional protein to your creamy mash. Just swap out the sour cream one-to-one.
  • Add more herbs. If desired, add some fresh parsley, fresh thyme, minced fresh rosemary, or green onions to your mash. 
  • Use a different potato. Any thin-skinned potatoes like creamers, baby potatoes, and yukon gold potatoes are great mashing. For skin-on mashed potatoes, small yellow, white, or red potatoes are perfect. If using larger sized potatoes, I recommend cutting them into smaller pieces (approximately 1-2” cubes) prior to boiling.
  • Add a splash of milk. If desired, you can add a splash of whole milk or cream during mashing to make these even creamier.
*For a smoother mashed potato consistency, using a potato ricer may be preferred.
