Traditional Country French Style Garlic Soup

If you ask me, garlic soup is one of those recipes that sounds odd until you try it.

This rustic French country soup turns humble garlic cloves into something warm and comforting. The garlic gets mellow and almost sweet as it simmers, creating a broth that’s rich without being heavy.

It comes together with just a handful of ingredients—garlic, broth, herbs, and bread for soaking up every last bit. A poached egg on top adds some richness and makes it feel like a real meal.

It’s the kind of simple, no-fuss dinner that’s perfect for a chilly evening when you want something satisfying without a lot of work.

What Kind of Garlic Should I Use?

For this soup, you’ll want to use a whole head of fresh garlic, and any variety you find at the grocery store will work just fine. Regular white garlic is the most common and will give you that classic garlic flavor, while purple-striped varieties tend to be a bit milder if you’re worried about the soup being too strong. When picking out your garlic head, look for one that feels firm and heavy with tight, papery skin – avoid any heads that feel soft or have started sprouting green shoots. Since you’re using a whole head, don’t stress too much about peeling each clove perfectly, as the garlic will soften up beautifully as it cooks in the broth.

Options for Substitutions

This simple soup has some room for adjustments if you need to work with what you have:

• Chicken stock: Vegetable stock works great here if you want to keep it vegetarian, or you can use beef stock for a richer flavor. Just keep in mind that beef stock will change the overall taste profile quite a bit.
• Fresh garlic: This soup really depends on garlic, so I wouldn’t recommend skipping it. However, if your garlic head is small, you might want to use two heads to get that full garlicky flavor.
• Dry sage: Fresh sage is actually better if you have it – use about 3 tablespoons of chopped fresh sage instead. You can also try thyme or a mix of herbs if sage isn’t your thing.
• Dijon mustard: Regular yellow mustard can work in a pinch, though it’s a bit milder. You could also use whole grain mustard for a slightly different texture.
• Olive oil: While olive oil adds a nice flavor, you can use a neutral oil like avocado or grapeseed oil if that’s what you have on hand.

Watch Out for These Mistakes While Cooking

The biggest mistake when making garlic soup is adding the egg yolk mixture to boiling hot stock, which will scramble the eggs instantly – instead, temper the yolk by slowly whisking in a ladle of warm stock first, then gradually add this mixture back to the pot while stirring constantly.

Another common error is burning the garlic during the initial cooking stage, so keep your heat at medium-low and watch it carefully since burnt garlic turns bitter and can ruin the entire soup.

When whisking in the olive oil to create the aioli-like finish, add it very slowly in a thin stream while whisking vigorously – dumping it in too fast will cause the mixture to separate and become greasy rather than smooth and creamy.

Finally, don’t skip the step of straining the soup if you want a silky texture, and remember that this soup is best served warm rather than piping hot, which helps preserve the delicate flavors.

What to Serve With Garlic Soup?

This garlic soup is rich and savory, so it pairs beautifully with crusty French bread or a warm baguette for dipping. I love serving it alongside a simple arugula salad dressed with lemon and olive oil to balance out the richness of the soup. A glass of dry white wine like Sauvignon Blanc also complements the garlic flavors nicely. If you want to make it more filling, add some roasted chicken or poached eggs right into the bowl for extra protein.

Storage Instructions

Store: Keep your garlic soup in an airtight container in the fridge for up to 4 days. Since this soup has egg yolk in it, make sure it cools down to room temperature before refrigerating, but don’t leave it sitting out for more than an hour or two.

Freeze: I wouldn’t recommend freezing this one because of the egg yolk and olive oil emulsion – it tends to separate and get a bit grainy when thawed. It’s best enjoyed fresh or within a few days from the fridge.

Reheat: Warm it gently on the stovetop over low heat, stirring often so the egg doesn’t scramble. You can also microwave it on medium power in short bursts, giving it a stir between each one. If it looks a bit separated, just whisk it back together as it warms up.

• Calories: 1450-1550
• Protein: 55-65 g
• Fat: 135-150 g
• Carbohydrates: 20-30 g

Ingredients

For the garlic preparation:

• 1 large garlic bulb (peeled and sliced)

For the soup base:

• 1 tbsp dried sage (I prefer Spice Islands)
• pinch 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)

Step 1: Roast the Garlic

• 1 large garlic bulb (peeled and sliced)
• 2/3 cup olive oil (extra virgin for better flavor, for drizzling)

Preheat your oven to 400°F (200°C).

Spread the sliced garlic bulb on a baking tray and drizzle lightly with a bit of olive oil.

Roast for 30-40 minutes, until the garlic is soft and golden.

This deepens the flavor and brings out its sweetness.

Step 2: Prepare the Chicken Stock

• 64 oz chicken stock
• 1 tbsp dried sage (I prefer Spice Islands)
• pinch salt

While the garlic is roasting, pour the chicken stock into a large pot.

Bring it to a gentle boil over medium-high heat.

Once boiling, add the dried sage and a pinch of salt, then lower the heat to a simmer.

Step 3: Mash the Roasted Garlic

• roasted garlic from Step 1

After roasting, remove the garlic from the oven and use a fork to mash it into a smooth paste.

I like to do this while the garlic is still warm—it mashes more easily.

Step 4: Make the Emulsified Mixture

• 1 egg yolk (room temperature)
• 1 tbsp Dijon mustard
• remaining olive oil from 2/3 cup

In a small bowl, whisk the egg yolk with Dijon mustard until smooth.

Slowly drizzle in the remaining olive oil while whisking continuously to create a creamy emulsion.

Step 5: Combine and Serve

• hot chicken stock with sage and salt from Step 2
• mashed roasted garlic from Step 3
• egg-mustard-oil emulsion from Step 4

Stir the mashed roasted garlic from Step 3 and the emulsified egg mixture from Step 4 into the hot chicken stock from Step 2.

Whisk well to blend.

Serve the soup hot, optionally with roasted slices of baguette on the side.
