Ingredients
Method
- Rinse and dice the potatoes, slice the leeks thin, dice the onion, and mince the garlic.
- Add all vegetables to the slow cooker.
- Pour in the vegetable broth and stir in thyme, salt, and pepper.
- Cover and cook on low for 6 hours.
- After cooking, use an immersion blender to puree the soup until smooth.
- Stir in the heavy cream and let the soup heat through for another 10 minutes.
- Taste and adjust seasoning if needed. Serve hot, garnished with chopped chives or a drizzle of olive oil if you like.
Notes
I always add a splash of heavy cream at the end to keep it silky, and I keep the leeks sliced very thin so they soften quickly. If you want a thicker soup, start with a small potato in the pot as a natural thickener.
