Equipment

  • Slow Cooker
  • Aluminum Foil or Baking Sheet

Ingredients
  

  • 4 cloves garlic bulbs whole, for roasting
  • 2 pounds potatoes russet or Yukon Gold, peeled and chopped
  • 1 tablespoon olive oil for roasting garlic
  • 4 cups vegetable broth
  • 1 cup milk or cream for creaminess
  • to taste salt and pepper

Instructions
 

  • Preheat the oven and roast whole garlic bulbs wrapped in foil until fragrant and golden, about 30-40 minutes.
  • Meanwhile, peel and chop the potatoes into uniform pieces, preparing them for even cooking and blending.
  • Once roasted and cool enough to handle, squeeze the soft garlic cloves out of their skins and set aside.
  • Add the chopped potatoes and roasted garlic to the slow cooker, then pour in the vegetable broth. Cover and turn on low for 6-8 hours until the potatoes are tender and flavors meld.
  • After cooking, use an immersion blender directly in the slow cooker to puree the soup until silky smooth, or transfer carefully to a blender in batches.
  • Stir in milk or cream to add richness and adjust seasoning with salt and pepper to taste. Warm the soup over low heat if needed to serve hot.
  • Spoon the velvety soup into bowls, garnishing with a swirl of cream, chopped herbs, or a drizzle of olive oil if desired. Serve hot and enjoy the deep, roasted garlic flavor and creamy texture.

Notes

For extra depth, toast some additional garlic or add a pinch of smoked paprika before blending.
