A treasured recipe from France's Lautrec region, this garlic soup transforms humble ingredients into liquid gold. The magic lies in the perfect marriage of garlic-infused broth with silky homemade mayonnaise, creating a velvety soup that warms both body and soul. Each spoonful delivers subtle garlic notes that have mellowed through careful cooking, making this rustic soup surprisingly refined.
I discovered this recipe during a cooking workshop in southern France, where the chef shared that his grandmother made this soup weekly. Since then, it's become my go-to comfort food during winter months, and I'm constantly amazed at how such simple ingredients create such profound flavor.
Ingredients For Success
- Chicken stock: Serves as your foundation, homemade brings the most flavor, but a high-quality store-bought stock works beautifully
- Fresh garlic: Should feel firm and heavy, with tight, papery skin, avoid heads with green sprouts or soft spots
- Olive oil: Quality matters tremendously here, choose a smooth, fruity variety that tastes good on its own
- Fresh sage leaves: Should be velvety and aromatic, avoid any with dark spots or yellowing
- Farm-fresh eggs: Will give your mayonnaise the richest color and flavor
Creating Your Soup
- Preparing The Base:
- Begin by examining each garlic clove carefully, removing any green sprouts which can add bitterness. Split each clove lengthwise, revealing their heart.
- Developing The Flavors:
- Gently simmer your stock with fresh sage, allowing the herb to slowly release its earthy notes. Meanwhile, the brief boiling of garlic cloves tames their raw bite while preserving their essential oils.
- Crafting The Mayonnaise:
- Take your time with this step, ensuring your ingredients are at room temperature. The slow drizzle of oil while blending creates an emulsion that will give your soup its signature texture.
- The Final Symphony:
- Watch carefully as you temper the mayonnaise with hot broth, whisking constantly to achieve that perfect, silky consistency.

In my kitchen, garlic has always held a special place. This soup taught me that garlic's true nature isn't about overwhelming power, but rather about its ability to transform into something gentle and nurturing when treated with respect.
Accompaniments With Soul
Serve this warming soup in pre-warmed bowls, topped with crusty baguette slices that have been rubbed with a garlic clove and toasted golden. A sprinkle of fresh herbs or a few drops of extra virgin olive oil add the perfect finishing touch.
Make It Your Own
Transform this classic by adding sautéed leeks for extra depth, or stir in some tender spinach leaves just before serving. For a heartier version, add small cubes of day-old bread during the final simmer, creating a garlic-infused bread soup reminiscent of Italian ribollita.
Preservation Practices
Store this soup in an airtight container in the refrigerator for up to three days. When reheating, do so gently over low heat, stirring occasionally. Never allow the soup to boil, as this can break the emulsion and affect the silky texture.

This French garlic soup represents everything I love about traditional cooking - taking humble ingredients and, through careful technique and patience, creating something that nourishes both body and spirit. Each time I make it, I'm transported back to that French kitchen where I first learned its secrets.
