Instructions

Step 1
Preheat your oven to 375°F (190°C) for the croutons.
Step 2
In a large pot, melt the butter over medium heat. Add leeks, onion, and garlic. Sauté for 6–8 minutes until softened but not browned.
Step 3
Add diced potatoes and cook for 2 more minutes.
Step 4
Pour in the vegetable broth, season with salt and pepper, and bring to a gentle boil. Reduce heat, cover, and simmer for 20 minutes until potatoes are tender.
Step 5
Meanwhile, toss sourdough cubes with olive oil, thyme, and sea salt. Spread on a baking sheet and bake for 10–12 minutes, turning once, until golden and crisp.
Step 6
Remove soup from heat. Use an immersion blender to blend until smooth and creamy (or transfer in batches to a blender, then return to the pot).
Step 7
Stir in the heavy cream and gently reheat without boiling. Adjust seasoning if needed.
Step 8
Ladle soup into bowls, top with sourdough croutons and a sprinkle of fresh chives.

Zusatztipps für die Zubereitung

To ensure the smoothest texture, make sure to peel the potatoes thoroughly and dice them into uniform pieces so they cook evenly. If you find your soup is too thick after blending, you can stir in a little extra vegetable broth until you reach your desired consistency. Always remember to clean the leeks carefully, as dirt often gets trapped between the tight layers.

Varianten und Anpassungen

For a vegan version, simply use plant-based butter and a plant-based cream or full-fat coconut milk. You can also give this soup a green nutritional boost by stirring in a handful of fresh spinach or watercress just before blending. If you want a gluten-free option, ensure you use a certified gluten-free bread for the croutons.

Serviervorschläge

Serve this soup in warmed bowls to keep it hot while you enjoy the crunchy croutons. It pairs wonderfully with a crisp white wine such as Sauvignon Blanc. For a bit of extra decadence, finish each bowl with a tiny drizzle of high-quality olive oil or an extra dusting of freshly cracked black pepper.
