  • Yield: 8 cups 1x


Cooked, mashed and served all in the slow cooker, this velvety, cheesy potato cauliflower mash makes a delicious and easy side dish and is a perfect for any holiday dinner.


  • 3 pounds (about 3 large) russet potatoes, peeled and chopped into 1-inch chunks
  • 1 1/2 pounds cauliflower florets (from 1 large head), cut into 6-8 wedges
  • 1 1/2 cups milk, divided
  • 1 cup chicken broth
  • 4 cloves garlic, minced or pressed
  • 1 teaspoon kosher salt
  • 1/2 teaspoon freshly ground black pepper
  • 1/2 cup grated parmesan cheese
  • 1/2 cup mascarpone cheese
  • 1 cup shredded sharp cheddar cheese
  • 4 tablespoons butter
  • 10 large sage leaves


  1. Layer potatoes in the bottom of the slow cooker. Place cauliflower on top and add garlic, 1 cup milk, chicken broth, salt and pepper and toss to coat.
  2. Cover and cook until fork tender, about 4-5 hours on high or 6-7 hours on low, gently mixing once halfway through.
  3. Mash to using a potato masher or electric mixer. Stir in the cheeses, cover, and cook another 5-10 minutes or until cheese has melted.
  4. While the cheese melts, melt butter in a small skillet over medium heat. Swirling the pan occasionally, watch for the color to change from yellow to golden-tan to a warm brown. Once brown, add the sage and cook for 30 seconds, stirring once or twice. Remove skillet from heat. Transfer sage to a paper towel-lined plate to remove excess butter and then coarsely chop.
  5. Just   before   serving,   heat   remaining   1⁄2   cup   milk   in   the   microwave   for   45-60   seconds   and   stir   into potatoes   until   desired   consistency   is   reached,   adding   more   if   necessary.   Stir   in   browned   butter and   sage   and   season   with   additional   salt   and   coarsely   ground   black   pepper,   if   desired.
