Roast the garlic first. Preheat your oven to 400°F (200°C). Cut the tops off the garlic bulbs to expose the cloves, place them on a piece of foil, drizzle with 1 tablespoon of olive oil, and wrap tightly. Roast for 30-35 minutes until the garlic is golden and soft.
Prepare your base while the garlic roasts. Heat the remaining 2 tablespoons of olive oil in a large pot over medium heat. Add the diced onions, carrots, and celery, and sauté for about 5-7 minutes until the vegetables soften.
Add the aromatics to build flavor. Stir in the dried thyme and smoked paprika, cooking for another minute until fragrant.
Incorporate the chickpeas and liquid. Add the drained chickpeas, vegetable broth, and bay leaf to the pot. Bring the mixture to a boil, then reduce to a simmer and cook for 15 minutes.
Add the roasted garlic. Once the garlic has cooled slightly, squeeze the soft cloves out of their skins directly into the soup. Remove the bay leaf.
Blend until smooth. Using an immersion blender, purée the soup until velvety smooth. If using a regular blender, work in batches and be careful with the hot liquid.
Finish with brightness. Stir in the fresh lemon juice and season with salt and pepper to taste. If the soup is too thick, add a little more broth or water to reach your desired consistency.
Serve with love. Ladle the soup into bowls, garnish with fresh herbs, and drizzle with a touch of good olive oil if desired.
