French Garlic Soup Recipe
Introduction
French Garlic Soup is a comforting and flavorful dish that highlights the rich aroma of roasted garlic combined with fresh sage and a velvety emulsified broth. This traditional soup is perfect for a cozy dinner or as a sophisticated starter to impress guests.

Ingredients
- 64 ounces chicken stock
- Small bunch fresh sage
- 1 large head of garlic
- 2/3 cup olive oil (or your preferred vegetable oil)
- 1 large egg, separated
- 1 tsp Dijon mustard
- Pinch of salt
Instructions
- Step 1: Heat the chicken stock and fresh sage in a large Dutch oven, bringing it to a gentle simmer.
- Step 2: Peel and halve the garlic cloves, removing the shoots from each.
- Step 3: Boil the prepared garlic in a small saucepan for 3 to 4 minutes, then drain thoroughly.
- Step 4: Mash the softened garlic and add it to the simmering stock. Let it continue to simmer gently for 10 minutes to infuse flavor.
- Step 5: In a small jar, combine the egg yolk, Dijon mustard, pinch of salt, and olive oil. Use an immersion blender to emulsify this mixture into a smooth mayonnaise.
- Step 6: Optionally, strain the soup for a smoother texture before tempering the mayonnaise. Gradually add hot soup to the mayonnaise while stirring to warm it gently.
- Step 7: Stir the tempered mayonnaise back into the soup. Warm the mixture gently on low heat without bringing it to a boil to prevent curdling.
- Step 8: Serve the soup hot, garnished with croutons, a drizzle of olive oil, a sprinkle of smoked paprika, and fresh herbs for an extra burst of flavor.
Tips & Variations
- For a vegetarian version, substitute chicken stock with vegetable broth and use a plant-based oil.
- Remove the garlic shoots to eliminate any bitterness and ensure a smooth, rich garlic flavor.
- If you prefer a thicker soup, add a small handful of crushed potatoes during simmering and blend before adding the mayonnaise.
- Use fresh herbs like thyme or rosemary in place of sage for a different aromatic profile.
Storage
Store leftover soup in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop over low heat without boiling to avoid breaking the emulsified texture. This soup does not freeze well due to the egg and oil mixture.

FAQs
Can I use pre-minced garlic instead of fresh garlic cloves?
Fresh garlic is preferred for its robust flavor and texture. Pre-minced garlic often lacks depth and may alter the soup’s taste, so it’s best to use fresh cloves for this recipe.
Is it safe to consume raw egg yolk in this soup?
The yolk is gently cooked by tempering it with hot soup and warming it without boiling. However, if you have concerns, use pasteurized eggs or omit the yolk, though this may affect the soup’s texture.

Ingredients
Soup Base
- 64 ounces chicken stock
- Small bunch fresh sage
- 1 large head of garlic
Emulsion
- 2/3 cup olive oil (or your preferred vegetable oil)
- 1 large egg, separated
- 1 tsp Dijon mustard
- Pinch of salt
Instructions
- Simmer the Stock: Heat the chicken stock and fresh sage together in a large Dutch oven over medium heat until it reaches a gentle simmer, infusing the soup with herbaceous flavors.
- Prepare the Garlic: Peel and halve each clove from the large head of garlic, taking care to remove the green shoots in the center which can impart bitterness.
- Soften the Garlic: Boil the garlic halves in a small saucepan of water for 3 to 4 minutes to mellow the garlic’s sharpness, then drain thoroughly.
- Mash and Add Garlic: Mash the softened garlic cloves into a smooth paste and stir this into the simmering stock, continuing to simmer gently for 10 minutes to meld the flavors.
- Make the Emulsion: In a small jar, combine the egg yolk, Dijon mustard, salt, and olive oil. Using an immersion blender, blend the mixture until it emulsifies into a creamy mayonnaise-like texture.
- Strain the Soup (Optional): For a smoother texture, strain the soup through a fine sieve to remove solids before adding the emulsion.
- Temper the Emulsion: Slowly add a ladle of the hot soup into the mayonnaise mixture while whisking constantly to gently warm it and prevent curdling.
- Combine and Warm: Stir the tempered mayonnaise into the pot of soup and warm gently over low heat without bringing it to a boil, ensuring a silky, creamy consistency.
- Serve: Ladle the soup into bowls and garnish with croutons, a drizzle of olive oil, a sprinkle of smoked paprika, and fresh herbs for an aromatic finish.
Notes
- Removing the garlic shoots helps reduce bitterness in the soup.
- Tempering the egg-based emulsion is crucial to avoid curdling.
- You can substitute chicken stock with vegetable stock for a vegetarian variation, but the egg and chicken stock together exclude vegan classification.
- Serve immediately after warming to maintain the silky texture.
- This soup pairs wonderfully with crusty bread.
