French Garlic Soup Recipe

French Garlic Soup (Soupe à l’Ail) is a delightful dish that transforms simple ingredients into a bowl of rustic elegance. Traditionally enjoyed in southern France, this soup combines the rich flavor of garlic with a silky texture, perfect for cold evenings or as a light first course. Surprisingly mellow despite its namesake, the slow-cooked garlic develops a sweet, aromatic flavor that pairs beautifully with crusty bread.

Here’s how to make this classic dish step by step.

Ingredients

For the Soup Base:

• 2 tablespoons olive oil or unsalted butter
• 2 heads (about 20-25 cloves) of garlic, peeled
• 1 large onion, finely chopped
• 2 sprigs of fresh thyme (or 1 teaspoon dried thyme)
• 1 bay leaf
• 6 cups chicken or vegetable stock
• 2 large egg yolks
• ½ cup heavy cream (optional)
• Salt and freshly ground black pepper to taste

For Serving:

• Crusty bread or baguette slices
• Grated Parmesan or Gruyère cheese (optional)
• Fresh parsley, chopped

Step-by-Step Instructions

Step 1: Prepare the Garlic

1. Peel the garlic cloves. To save time, you can blanch them in boiling water for 30 seconds, then cool them in ice water—the skins will slip off easily.
2. If you prefer a milder garlic flavor, simmer the peeled cloves in water for 2 minutes and drain before using.

Step 2: Sauté the Aromatics

1. Heat olive oil or butter in a large pot over medium heat.
2. Add the garlic cloves and cook gently for 5-7 minutes, stirring occasionally, until lightly golden and aromatic.
3. Stir in the chopped onion and cook until translucent, about 5 minutes.

Step 3: Simmer the Soup

1. Add the thyme, bay leaf, and chicken or vegetable stock to the pot.
2. Bring the mixture to a boil, then reduce the heat and simmer uncovered for 30 minutes. The garlic should be tender and starting to break down.

Step 4: Blend and Thicken

1. Remove the thyme sprigs and bay leaf. Use an immersion blender to puree the soup until smooth, or carefully transfer it to a blender and blend in batches.
2. In a small bowl, whisk together the egg yolks and cream (if using). Temper the mixture by slowly adding a ladle of hot soup while whisking to prevent curdling.
3. Stir the tempered mixture back into the soup and heat gently for another 2-3 minutes without boiling.

Step 5: Season and Serve

1. Taste and season the soup with salt and freshly ground black pepper.
2. Ladle the soup into bowls and garnish with fresh parsley, grated cheese, and a drizzle of olive oil if desired. Serve with crusty bread or baguette slices on the side.

Serving Tips

• For an authentic French touch, top the bread slices with grated cheese and toast them under a broiler until golden, then float them on top of the soup.
• Pair the soup with a simple green salad dressed with vinaigrette for a complete meal.

Storage Tips

• Refrigeration: Store the soup in an airtight container in the fridge for up to 3 days. Reheat gently on the stovetop.
• Freezing: Garlic soup freezes well. Store in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating.

Helpful Notes

• Garlic Varieties: Use fresh, firm garlic for the best flavor. Avoid old garlic, which can taste bitter.
• Texture Variation: If you prefer a chunkier soup, blend only half the soup and leave the rest as is.
• No Cream? No Problem: This soup is just as delicious without cream. The blended garlic provides a creamy texture on its own.

Tips from Well-Known Chefs

• Jacques Pépin: Use a mix of roasted and raw garlic for depth and complexity in the flavor.
• Julia Child: A dash of white wine added during cooking enhances the soup’s French flair.
• Raymond Blanc: To mellow the garlic further, roast it in the oven at 375°F (190°C) for 20 minutes before adding it to the soup.
