  • 1.5 lb baby gold potatoes
  • 1 lb cauliflower florets (~1 small head)
  • 2 C broth of choice, divided (3/4 C reserved)
  • 4-5 C water
  • 1 Tbsp salted butter + more for serving
  • 1/2 C sour cream
  • 1/4 tsp salt + add'l salt & pepper to taste
  • 1/4 C chopped chives
  • optional: other finely chopped herbs like parsley, rosemary, and/or thyme


  • Place potatoes and cauliflower in a large saucepan with 1 + 1/4 cup broth and enough water to just cover the vegetables. Boil until potatoes are fork tender (~15-20 minutes)
  • Reserve 1/2 cup of the cooking liquid and set aside. Drain the remaining liquid
  • In the same pan, mash the cooked potatoes and cauliflower with 3/4 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!


*For a smoother mashed potato consistency, using a potato ricer may be preferred.
*Alternate potato option if you do not have baby gold or fingerling potatoes: Yukon gold or russet potatoes will also work great in this cauliflower and potato mash recipe! Since these are larger potatoes, you will need to cut them into smaller pieces (approximately 1-2” cubes) prior to boiling.
