  • 32 ounces Riced cauliflower frozen
  • 3 tablespoons Unsalted butter
  • 2 cups Water
  • 1 teaspoon Kosher salt
  • 1/2 tsp Black pepper
  • 2 cloves Garlic minced


  • Sauté the cauliflower: Melt the butter in a large pot over medium-high heat. Add the cauliflower and sauté, stirring regularly, until the cauliflower has lightened in color, about 3 to 5 minutes.
  • Boil cauliflower: Add water and salt and bring to a boil. Cover and cook until the cauliflower is tender, about 10 minutes.
  • Drain the cauliflower but reserve 1/4 cup of the cooking liquid.
  • Mash or purée: Place the drained cauliflower, minced garlic, pepper and reserved cooking liquid back in the pot. Mash using an immersion blender, a high speed blender or food processor to desired consistency.
  • Serve.
