Ingredients
- For the roasted garlic:
- 3 whole heads garlic, top 3 mm (1/8 inch) removed
- 15 ml (1 tablespoon) olive oil
- For the soup:
- 15 ml (1 tablespoon) olive oil
- 1 medium onion, diced (approximately 150-200g)
- 3 cloves garlic, chopped (approximately 15g)
- 950 ml (4 cups) chicken broth or vegetable broth
- 3 cans (each 410 g / approximately 15 ounces) white beans, such as cannellini or great northern, rinsed and drained
- 10 g (2 teaspoons) fresh rosemary, finely chopped (or 5 g (1 teaspoon) dried rosemary)
- 25 g (1/4 cup) Parmigiano Reggiano, freshly grated (optional, for serving or blending)
- 15 ml (1 tablespoon) fresh lemon juice
- Salt, to taste
- Freshly ground black pepper, to taste
Instructions
- Prepare the garlic for roasting by preheating your oven to 180°C (350°F). Slice off the very top portion, about 3 mm (1/8 inch), of each garlic head to expose the cloves. Place the garlic heads on a piece of aluminium foil, drizzle generously with 15 ml (1 tablespoon) of olive oil, ensuring it seeps into the exposed cloves.
- Tightly wrap each garlic head in its individual piece of aluminium foil. Place the wrapped garlic on a baking sheet and roast in the preheated oven for approximately 60 to 90 minutes, or until the cloves are golden brown, deeply fragrant, and very tender when squeezed. The longer roasting time allows for maximum caramelization and mellow sweetness.
- While the garlic roasts, begin the soup base. Heat 15 ml (1 tablespoon) of olive oil in a large, heavy-bottomed saucepan or Dutch oven over medium heat. Add the diced onion and cook, stirring occasionally, until it becomes soft and translucent, about 5 to 7 minutes. Do not brown the onion, as this can affect the soup's final color.
- Add the 3 cloves of chopped garlic to the softened onion. Continue to cook for about 1 minute, stirring constantly, until the garlic is fragrant. Be careful not to burn the garlic, as it can turn bitter very quickly.
- Pour in the 950 ml (4 cups) of chicken or vegetable broth, add the rinsed and drained white beans, and the chopped fresh or dried rosemary. Bring the mixture to a gentle boil, then reduce the heat to low and let it simmer for 5 minutes. This allows the flavors to meld and the rosemary to infuse the broth.
- Carefully remove the roasted garlic from the oven and unwrap it once it's cool enough to handle. Squeeze the soft, caramelized garlic cloves directly from their skins into the simmering soup. Discard the papery skins.
- Using an immersion blender directly in the pot, or carefully transferring the soup in batches to a countertop blender, purée the soup until it is completely smooth and creamy. If using a countertop blender, be sure to vent the lid to allow steam to escape and avoid pressure buildup.
- Stir in the 25 g (1/4 cup) of grated Parmigiano Reggiano (if using), which adds a wonderful savory depth. Incorporate the 15 ml (1 tablespoon) of fresh lemon juice, which brightens the entire dish and balances the richness. Taste the soup and season generously with salt and freshly ground black pepper as needed. Remember that broth and Parmesan can contribute salt, so season gradually.
- Serve the Rosemary Roasted Garlic Bean Soup immediately, garnished with a drizzle of olive oil, a sprinkle of fresh rosemary, or extra Parmigiano Reggiano if desired. This soup is best enjoyed warm and fresh.
Tools You’ll Need
- Oven
- Baking sheet
- Aluminium foil
- Large, heavy-bottomed saucepan or Dutch oven
- Cutting board and sharp knife
- Immersion blender or countertop blender
- Measuring cups and spoons
- Grater (if using fresh Parmigiano Reggiano)
Essential Success Tips
- Don't rush the garlic roasting process; the longer it roasts, the sweeter and more complex its flavor will become, which is crucial for the soup's depth.
- Ensure the onions are fully translucent before adding garlic to prevent any raw onion flavor in the finished soup.
- When puréeing, make sure to achieve a completely smooth consistency for the best mouthfeel; blend for an extra minute or two if needed.
- Always add the lemon juice at the end; it brightens the flavors significantly and prevents the soup from tasting flat.
- Taste and adjust seasoning meticulously at the end. Salt and pepper are critical for balancing the rich flavors.
Professional Cooking Secrets
- To achieve an even deeper, nuttier flavor in your roasted garlic, consider roasting it at a slightly lower temperature (160°C/325°F) for a longer period (up to 2 hours). This slow roast ensures maximum caramelization without any bitterness.
- For an extra layer of savory complexity, before sautéing the onion, bloom a pinch of red pepper flakes or a teaspoon of smoked paprika in the hot olive oil for 30 seconds. This infuses the oil with an aromatic foundation.
- If you want to add more texture, reserve a small portion of the puréed roasted garlic and a few whole white beans. Stir them back into the soup after blending for a subtle contrast against the creamy base.
Notes
- Storage: Leftover soup can be stored in an airtight container in the refrigerator for up to 3-4 days. It also freezes well for up to 3 months. Thaw overnight in the refrigerator and reheat gently on the stovetop.
- Variations: For a heartier soup, consider adding some sautéed spinach or kale during the last few minutes of simmering. A swirl of pesto before serving also adds a wonderful herbaceous kick. To make it vegan, ensure you use vegetable broth and omit the Parmigiano Reggiano, or use a vegan Parmesan alternative.
Frequently Asked Questions
Can I use pre-minced garlic for the soup base?
While fresh garlic is always recommended for the best flavor, you can use pre-minced garlic in a pinch. However, for the roasted garlic, whole heads are essential to achieve that distinct sweet, mellow flavor.
What kind of white beans are best for this soup?
Cannellini beans (white kidney beans) are ideal for their creamy texture when blended. Great northern beans or even navy beans would also work well, offering a similar mild flavor and smooth consistency.
How can I make this soup thicker or thinner?
To make the soup thicker, you can simmer it a bit longer after puréeing to allow some liquid to evaporate, or add a few more pre-cooked white beans before blending. If it's too thick, simply thin it out with a little extra broth or water until it reaches your desired consistency.
