4.8 from 93 reviews

This traditional Country French Style Garlic Soup is a rustic, comforting dish that transforms simple garlic cloves into a rich, mellow, and flavorful broth. Made with roasted garlic, chicken stock, dried sage, and a creamy emulsion of egg yolk, Dijon mustard, and olive oil, this soup is perfect for cozy evenings. The roasting mellows the garlic’s sharpness into a buttery sweetness, while the silky egg emulsion adds luxurious texture and depth. Ready in under an hour, it’s an impressive yet easy recipe that pairs beautifully with crusty French bread or a light salad.

Ingredients

Scale

For the Garlic Preparation:

  • 1 large garlic bulb (peeled and sliced)
  • Olive oil for drizzling (part of the 2/3 cup used in the emulsion step)

For the Soup Base:

  • 1 tbsp dried sage (preferably Spice Islands brand)
  • Pinch of salt
  • 64 oz (8 cups) chicken stock

For the Emulsion:

  • 2/3 cup extra virgin olive oil (divided: some for roasting garlic, remaining for emulsifying)
  • 1 tbsp Dijon mustard
  • 1 egg yolk (room temperature)

Instructions

  1. Roast the Garlic: Preheat your oven to 400°F (200°C). Spread the sliced garlic bulb evenly on a baking tray and drizzle lightly with a portion of the olive oil. Roast in the oven for 30-40 minutes until the garlic becomes soft, golden, and fragrant. Roasting mellows the raw garlic’s pungency and brings out sweetness.
  2. Prepare the Chicken Stock: While the garlic roasts, pour the chicken stock into a large pot and bring it to a gentle boil over medium-high heat. Add the dried sage and a pinch of salt. Reduce heat to low and let it simmer gently to infuse the flavors.
  3. Mash the Roasted Garlic: Once roasted, remove the garlic from the oven and while still warm, mash it thoroughly with a fork until it forms a smooth, buttery paste. The warmth makes it easier to mash finely.
  4. Create the Egg-Yolk Emulsion: In a small bowl, whisk the egg yolk together with Dijon mustard until smooth. Slowly drizzle in the remaining olive oil very gradually while whisking continuously and vigorously to create a creamy, stable emulsion similar to an aioli. Add the olive oil in a thin stream to avoid separation.
  5. Combine and Serve: Stir the mashed roasted garlic paste and the emulsified egg mixture into the hot, but not boiling, chicken stock. Whisk everything thoroughly for a smooth, well-blended soup. Serve the soup warm immediately, optionally accompanied by roasted slices of crusty baguette for dipping.

Notes

  • Make sure to add the egg yolk mixture to warm stock to avoid scrambling the eggs; temper the yolk by whisking in some warm stock first if needed.
  • Keep the oven temperature moderate to avoid burning garlic, which turns the soup bitter.
  • Add olive oil slowly during emulsification to achieve a creamy texture instead of greasy separation.
  • Strain the soup for a silky smooth finish if desired.
  • Serve the soup warm rather than piping hot to preserve delicate flavors.
  • Store in an airtight container in the refrigerator for up to 4 days; do not freeze.
  • Reheat gently on the stovetop over low heat or in short microwave bursts, stirring often to avoid egg curdling.
