Roasted Garlic
- 26 garlic cloves, peeled
- 2 Tablespoons olive oil
- Salt and freshly ground black pepper, a dash each
Soup Base
- 2 Tablespoons butter
- 2 medium onions, sliced (about 2 generous cups)
- 2 teaspoons chopped fresh thyme, or ½ teaspoon dried thyme
- 18 garlic cloves, smashed and peeled
- 4 cups chicken broth, low-sodium or vegetable broth
- 1 large russet potato, not peeled, cut into large chunks (optional)
Finishing Ingredients
- ½ cup whipping cream (or half and half, oat milk, or almond milk)
- ½ teaspoon sea salt
- ½ teaspoon freshly ground black pepper
- ½ cup finely grated Parmesan cheese
- 4 lemon wedges
Optional Garnishes
- Toasted croutons (drizzled with oil, salt, and pepper and baked at 350°F until golden)
- 8 cloves fresh garlic, minced and sautéed in olive oil until fragrant with a dash of pepper
- Parmesan crisps (see instructions below)
- Roast the garlic: Preheat the oven to 350°F. Cut the bottom portion where the garlic bulbs attach to the base to expose cloves. Optionally, lightly smash cloves to make peeling easier. Place 26 peeled garlic cloves into a small glass baking dish. Drizzle with 2 tablespoons olive oil, add a dash of salt and pepper, and toss to coat evenly. Cover tightly with foil or a lid and bake for about 45 minutes until garlic is golden brown and tender. Transfer roasted garlic cloves to a bowl. You may prepare this step a day ahead and refrigerate the cooled garlic for convenience.
- Sauté onions and thyme: In a heavy large saucepan, melt 2 tablespoons butter over medium-high heat. Add sliced onions and 2 teaspoons fresh thyme (or ½ teaspoon dried). Cook until onions are translucent and soft, about 5 minutes, stirring occasionally.
- Add garlic: Add the roasted garlic cloves along with 18 smashed raw garlic cloves to the saucepan. Cook for about 2 minutes to release the raw garlic’s aroma and oils, stirring gently.
- Add potato (optional): If using, add large chunks of a peeled russet potato to the pan now. This adds creaminess and thickness to the soup.
- Add broth and simmer: Pour in 4 cups of low-sodium chicken or vegetable broth. Cover the pan and let the soup simmer gently for about 20 minutes until the garlic and potatoes are very tender.
- Puree the soup: If using the potato, remove the chunks after simmering and set aside. Use an immersion blender directly in the pot or transfer the soup in batches to a blender. Puree until completely smooth. Return the potato chunks back into the pureed soup for texture.
- Finish the soup: Return the soup to the saucepan and stir in ½ cup whipping cream (or your preferred milk alternative). Warm the soup gently over low heat to reheat without boiling, to avoid curdling the milk. Season with ½ teaspoon sea salt and ½ teaspoon freshly ground black pepper. Adjust seasoning to taste.
- Prepare garnishes: While soup simmers, optionally make Parmesan crisps: Preheat oven to 400°F. On silicone or parchment-lined baking sheets, place heaping tablespoons of grated Parmesan cheese, flatten slightly, and space about ½ inch apart. Bake until golden and crisp, about 3 to 10 minutes depending on your oven. Let cool, then carefully lift off. For toasted croutons, drizzle bread cubes with olive oil, salt, and pepper, then bake at 350°F until golden. For sautéed garlic garnish, gently cook minced fresh garlic in olive oil until fragrant.
- Serve: Divide ½ cup grated Parmesan cheese evenly among 4 bowls (about 2 tablespoons each). Ladle hot soup over the cheese. Squeeze a lemon wedge into each bowl and garnish with optional Parmesan crisps, toasted croutons, or sautéed garlic for enhanced flavor and texture.
