Leek and Potato Soup
This Classic Leek and Potato Soup is the ultimate "hug in a bowl". Known in French cuisine as Potage Parmentier, it is a timeless masterpiece of simplicity, turning humble root vegetables into a silk-textured, elegant meal.The beauty of this soup lies in the mellow, sweet flavor of the leeks. Unlike onions, which can be sharp, leeks provide a soft, buttery onion-like base that pairs perfectly with the creamy, starchy heart of the potatoes. Finished with a touch of cooking cream and fresh herbs, it is sophisticated enough for a dinner party but comforting enough for a rainy Tuesday night.💡 This soup is a chameleon! Serve it steaming hot in the winter for maximum comfort, or follow the French tradition and serve it chilled (as Vichyssoise) during the hot summer months for a refreshing, gourmet lunch.

Instructions
Sauté the Aromatics:
- In a large pot over medium heat, melt the butter with the olive oil. Add the garlic and sliced leeks. Season with salt and black pepper.3 Leek, 4 Garlic Cloves, 1 Tbsp Butter, 2 Tbsp Olive Oil, ½ Tsp Salt, ½ Tsp Black Pepper
Soften the Leeks:
- Cook the leeks for about 10 minutes, stirring occasionally, until they are soft and translucent.
- Tip: Do not let them brown; you want to keep the soup's color light and the flavor delicate.
Simmer the Base:
- Add the potato cubes, bay leaves, fresh thyme sprigs, and vegetable broth.3 Medium Potato, 2 Bay Leaves, 3 to 4 Sprigs Fresh Thyme, 5 Cups Vegetables Broth
Cook until Tender:
- Bring the mixture to a boil, then reduce the heat to low. Cover and simmer for 20 minutes, or until the potatoes are fork-tender and starting to break apart.
Infusion Check:
- Carefully "fish out" and discard the thyme stems and the bay leaves.
Blend to Perfection:
- Using a hand blender (immersion blender), blend the vegetables directly in the pot until the soup is completely smooth and creamy.
The Creamy Finish:
- Pour in the cooking cream. Stir well and let the soup simmer on low heat for an additional 5 to 10 minutes to allow the flavors to marry and the texture to thicken slightly.1 cup Cooking Cream

Notes
Serving suggestions:
To make this a complete meal, serve it with a warm, crusty baguette or garlic herb crostini. The crunch of the bread dipped into the velvety soup is a match made in culinary heaven.
Note:
If you are a meal-prepper, make a double batch of the base (Leeks + Potatoes + Broth) and freeze half. When you're ready for a quick gourmet dinner, simply reheat, blend, and stir in fresh cream!

❄️ Storage & Freezing Guide
In the Fridge:
- Storage: Allow the soup to cool completely before transferring it to an airtight container. It stays fresh for 3 to 4 days.
- The "Thickening" Effect: Potatoes are full of starch, which means the soup will become much thicker (almost like a mash) once chilled.
- Reheating: Heat it slowly in a pot over medium-low heat. Add a splash of broth or water while stirring to bring it back to its original silky consistency.
- The Dairy Rule: If you plan on freezing a large batch, it is best to freeze the soup before adding the cooking cream. Dairy can sometimes grain or separate when thawed.
- Storage: Use freezer-safe bags or containers, leaving 2cm of space at the top for expansion. It lasts for up to 3 months.
- Thawing: Thaw in the fridge overnight. If the texture looks slightly "separated" after thawing, don't worry! A quick 30-second pulse with the hand blender after reheating will make it perfectly smooth again.
