I love this delicious fake take on mashed potatoes, and it doesn't heat up my kitchen! Treat leftovers as you would leftover mashed potatoes and make mock potato pancakes. —Sharon Gibson, Hendersonville, North Carolina

  • 1 teaspoon minced fresh rosemary or 1/2 teaspoon dried rosemary, crushed
  • 1/4 cup heavy cream, warmed
  • Optional: Additional minced fresh rosemary and pepper


  1. Place melted butter and onion in a 4- or 5-qt. slow cooker. Add cauliflower; cook, covered, on high 3-4 hours or until cauliflower is tender.

Test Kitchen tips
  • The garlic really comes through from the cheese spread. For less garlic flavor, use only part of the spread in the recipe.
  • Replace the heavy cream with half-and-half cream or 2% milk for a lighter version of this recipe.
  • Health Tip: At only 11g carbohydrates per serving, this is a flavorful lower-carb alternative to mashed potatoes.
