4.8 from 92 reviews

This traditional country French style garlic soup is a rustic, comforting dish that transforms humble garlic cloves into a rich, mellow broth with sweet, buttery flavors. Roasted garlic is combined with sage-infused chicken stock and finished with a creamy egg yolk and olive oil emulsion, creating a silky, satisfying soup perfect for cozying up on chilly evenings.

Ingredients

Scale

For the Garlic Preparation:

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

For the Soup Base:

  • 1 tbsp dried sage (Spice Islands preferred)
  • Pinch of salt
  • 64 oz chicken stock

For the Emulsion:

  • 2/3 cup olive oil (extra virgin for better flavor)
  • 1 tbsp Dijon mustard
  • 1 egg yolk (room temperature)

Instructions

  1. Roast the Garlic: Preheat the oven to 400°F (200°C). Spread the sliced garlic on a baking tray and lightly drizzle with a small amount of olive oil. Roast for 30-40 minutes until the garlic is soft and golden, which enhances its sweetness and mellows its sharpness.
  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 once boiling, then reduce the heat to a simmer to develop the flavors.
  3. Mash the Roasted Garlic: Remove the garlic from the oven and mash it with a fork into a smooth paste while still warm, as warm garlic is easier to mash and blend into the soup.
  4. Make the Emulsified Mixture: In a small bowl, whisk together the egg yolk and Dijon mustard until smooth. Slowly drizzle the remaining olive oil (from the 2/3 cup) into the mixture while whisking vigorously to create a creamy, smooth emulsion similar to aioli.
  5. Combine and Serve: Stir the mashed roasted garlic and emulsified egg mixture into the hot chicken stock with sage and salt. Whisk thoroughly to combine all ingredients into a silky soup. Serve immediately, optionally with roasted slices of baguette for dipping.

Notes

  • Use a whole head of fresh garlic; purple-striped varieties are milder, while white garlic offers classic flavor.
  • To avoid scrambled eggs, temper the egg yolk by slowly whisking in some warm stock before adding it back to the pot.
  • Keep the roasting temperature medium-low to middle to prevent burnt garlic, which makes the soup bitter.
  • Whisk olive oil in slowly to avoid separation and achieve a creamy emulsion.
  • Strain the soup if you desire a silky texture, but it can also be served rustic without straining.
  • Serve the soup warm rather than piping hot to preserve delicate flavors.
  • Store in an airtight container in the fridge for up to 4 days; do not freeze due to egg yolk and olive oil emulsion separation.
  • Reheat gently on the stove or microwave in short bursts, stirring often.
  • Pairs well with crusty French bread and a simple arugula salad dressed with lemon and olive oil.
  • Optional: Add poached eggs or roasted chicken for extra protein and heartiness.
