Ingredients You’ll Need

This Ratatouille Soup comes together with a handful of humble ingredients, each playing a vital role in building layers of flavor, texture, and color. From the sweetness of leeks and onions to the earthy mushrooms and fragrant fresh herbs, every component brings something special to the pot.

2 tablespoons olive oil: Provides a fruity base and helps soften the vegetables beautifully.
2 yellow onions, chopped: Adds a natural sweetness and depth when sautéed.
2 leeks (white part only), chopped (~1 cup): Gives a gentle, onion-like aroma and smooth texture.
3 garlic cloves, chopped: Infuses the soup with classic aromatic warmth.
8 oz (250 g) brown mushrooms, chopped: Lends earthiness and a meaty bite to the soup.
3 cups (300 g) peeled and cubed potatoes (~10 oz): Adds creaminess and body once cooked and blended.
1 teaspoon salt: Essential for balancing and enhancing all the flavors.
Pinch of black pepper: Offers gentle heat and spice.
5 cups (1.15 l) broth: The flavorful liquid base—vegetable or chicken broth works great.
½ cup (115 ml) dry white wine (optional): Contributes subtle acidity and complexity.
1 sprig of fresh thyme, chopped: Adds a woody note that brightens the soup.
1 sprig of fresh parsley, chopped: Brings a fresh, herbaceous lift.
1 sprig of fresh marjoram: Offers a delicate floral and citrus aroma.
1 sprig of fresh lemon balm: Infuses a light, lemony essence that wakes up the flavors.
1 cup (40 g) grated Parmesan or nutritional yeast: Adds umami richness or keeps it vegan-friendly.
½ cup (115 ml) heavy cream or plant-based cooking cream: Creates the luxurious, creamy finish.

How to Make Ratatouille Soup

Step 1: Sauté the Aromatics

Start by heating the olive oil in a large soup pot over medium heat. Add the chopped onions and leeks, stirring occasionally until they soften soften and turn translucent, about 3 to 5 minutes. This gentle cooking releases their natural sweetness, laying a flavorful foundation for the soup.

Step 2: Cook the Mushrooms and Garlic

Add the chopped mushrooms, garlic, salt, and pepper to the pot. Stir continuously as the mushrooms release their moisture and begin to caramelize to a beautiful golden brown. This step deepens the soup’s flavor profile with rich earthiness and savory notes. It usually takes around 5 minutes, so keep your eyes on the pan to avoid burning.

Step 3: Simmer with Potatoes, Broth, and Herbs

Now it’s time to add the potatoes, broth, and white wine if you’re using it. Toss in all the fresh chopped herbs—thyme, parsley, marjoram, and lemon balm. Bring everything to a gentle simmer, cover the pot, and let it cook for 15 to 20 minutes. The potatoes should be tender but not falling apart, offering the perfect texture for blending later.

Step 4: Blend and Enrich the Soup

Remove the herb sprigs from the pot, then stir in the grated Parmesan and heavy cream (or your chosen alternatives). Let the cheese melt and the cream swirl through the soup, enriching it with lushness. After this, allow the soup to cool slightly, then blend it with an immersion blender or in batches with a stand blender until you reach your preferred consistency—smooth and creamy or a bit chunkier if you like texture.
