  • Roasted Garlic: 4 large heads of garlic, 2 tablespoons olive oil
  • Soup Base: 2 tablespoons unsalted butter, 1 medium yellow onion (finely chopped), 1 large russet potato (peeled and diced), 4 cups low-sodium vegetable broth, 1 cup whole milk or unsweetened plant-based milk, 1/2 teaspoon dried thyme, 1 bay leaf, Salt and freshly ground black pepper (to taste)
  • Garnish: 2 tablespoons chopped fresh parsley, Croutons or toasted bread (optional)

Instructions

Step 1: Roast the Garlic
Preheat oven to 400°F (200°C). Slice the tops off the garlic heads to expose the cloves. Drizzle with olive oil, wrap in foil, and roast for 35-40 minutes until soft and golden. Allow to cool slightly, then squeeze the roasted garlic out of the skins.
Step 2: Sauté Aromatics
In a large pot, melt butter over medium heat. Add chopped onion and sauté until translucent, about 5 minutes.
Step 3: Simmer the Soup
Add diced potato, roasted garlic, thyme, bay leaf, and vegetable broth. Bring to a boil, then reduce heat and simmer for 15 minutes, or until potatoes are tender.
Step 4: Blend to Smooth
Remove the bay leaf. Use an immersion blender to purée the soup until smooth, or transfer to a blender in batches.
Step 5: Final Touches
Return the soup to the pot. Stir in milk and heat gently until warmed through. Season with salt and pepper to taste.
Step 6: Serve and Garnish
Ladle into bowls and garnish with parsley and optional croutons or toasted bread.
