Ingredients

Instructions

  1. Step 1: Peel and dice 2 pounds of celeriac into 1-inch cubes. Place the diced celeriac, 2 quartered shallots, and 6 peeled garlic cloves into a large pot. Add 1 cup vegetable broth and enough water to cover the vegetables by 1 inch. Bring to a boil over high heat.
  2. Step 2: Reduce the heat to medium and simmer the vegetables for 20-25 minutes until the celeriac is very tender when pierced with a fork. Drain the vegetables, reserving 1/4 cup of the cooking liquid.
  3. Step 3: Transfer the celeriac, shallots, and garlic to a large bowl. Add 3 tablespoons unsalted butter and 1/2 cup heavy cream. Mash with a potato masher or use a hand blender until smooth and creamy, adding reserved cooking liquid as needed to reach desired consistency. Season with 1 teaspoon salt and 1/2 teaspoon black pepper and mix well.
