Roasted Garlic Soup

Featured in: Home Meal Favorites

This roasted garlic soup delivers a luxurious, velvety texture that's both comforting and nourishing. The roasting process transforms sharp garlic into something sweet and mellow, creating depth without any harsh bite. A russet potato adds natural creaminess while keeping the soup light and vegetarian-friendly.

The preparation comes together in just over an hour, with most of that time being hands-off roasting. You'll sauté onions until translucent, simmer everything in vegetable broth with thyme, then blend until satiny smooth. A splash of milk finishes it beautifully.

Perfect for cold weather or whenever you need something soothing, this soup adapts easily to vegan diets with plant-based butter and milk. The result is an elegant, immunity-boosting bowl that tastes like it came from a fine bistro.

Instructions

Step 1: Roast the Garlic
Preheat oven to 400°F (200°C). Slice the tops off the garlic heads to expose the cloves. Drizzle with olive oil, wrap in foil, and roast for 35-40 minutes until soft and golden. Allow to cool slightly, then squeeze the roasted garlic out of the skins.
Step 2: Sauté the Onion
In a large pot, melt butter over medium heat. Add chopped onion and sauté until translucent, about 5 minutes.
Step 3: Simmer the Base
Add diced potato, roasted garlic, thyme, bay leaf, and vegetable broth. Bring to a boil, then reduce heat and simmer for 15 minutes, or until potatoes are tender.
Step 4: Purée the Soup
Remove the bay leaf. Use an immersion blender to purée the soup until smooth, or transfer to a blender in batches.
Step 5: Finish and Season
Return the soup to the pot. Stir in milk and heat gently until warmed through. Season with salt and pepper to taste.
Step 6: Garnish and Serve
Ladle into bowls and garnish with parsley and optional croutons or toasted bread.

Zusatztipps für die Zubereitung

To save time, you can prepare the roasted garlic in advance and keep it refrigerated. When it comes to blending, using an immersion blender directly in the pot is the easiest method for achieving that perfect, velvety consistency.

Varianten und Anpassungen

For a vegan-friendly version, simply substitute the butter and milk with plant-based alternatives like vegan butter and unsweetened almond or oat milk. If you enjoy a bit of warmth, a pinch of cayenne pepper can be added for a subtle heat that complements the garlic's sweetness.

Recipe FAQs

How does roasting garlic change its flavor?

Roasting transforms pungent raw garlic into something sweet, mellow, and subtly nutty. The high heat caramelizes the natural sugars, removing any harsh bite while creating deep, savory complexity that forms the soul of this soup.

Can I make this soup ahead of time?

Absolutely. This soup actually tastes better the next day as flavors meld together. Store in an airtight container in the refrigerator for up to 4 days. Reheat gently over medium-low heat, adding a splash of broth or milk if needed to restore consistency.

What creates the creamy texture without heavy cream?

The russet potato breaks down during simmering, releasing natural starches that create luxurious body and silkiness. Combined with puréed roasted garlic and a modest amount of milk, you get velvety richness without relying on heavy cream.

Is this suitable for meal prep?

Perfect for meal prep. The roasted garlic can be prepared up to 3 days in advance and refrigerated. The soup itself freezes well for up to 3 months—just cool completely before freezing and leave a bit of headspace in containers for expansion.

What can I serve with this soup?

Crusty bread, toasted baguette slices, or homemade croutons create lovely texture contrast. A simple green salad with vinaigrette balances the richness. For a heartier meal, pair with a grilled cheese sandwich or savory tart.

How do I adjust the garlic intensity?

The roasting naturally mellows garlic, but you can easily adjust. For more pronounced garlic flavor, add an extra head during roasting. If you prefer subtler notes, use only 3 heads. Taste after puréeing before adding final seasonings.
