Step-by-Step Instructions
Preparing the Vegetables
Start by peeling and chopping the potatoes into bite-sized pieces. I like to use russet potatoes for their creamy texture. Next, clean the leeks and slice only the white and light green parts. They add a sweet flavor. Dice the onion and finely mince the garlic. Set everything aside for now.
Slow Cooking the Soup
In your slow cooker, pour in the extra virgin olive oil. Set it to medium-high heat. Add the diced onions and sliced leeks. Sauté them for about 5-7 minutes until soft and fragrant. If you’re in a hurry, skip this step. Just add the onions and leeks with the other ingredients straight away. Now, add the chopped potatoes, minced garlic, dried thyme, and vegetable broth. Season with sea salt and cracked black pepper. This step brings out all the great flavors. Cover the slow cooker with its lid. Let it cook on low for 6-8 hours or on high for 3-4 hours. The potatoes should be soft and easily pierced with a fork.
Blending and Final Adjustments
After cooking, use an immersion blender to puree the soup. Blend until it reaches your desired smoothness. If you like some texture, blend just half of it. Next, stir in the heavy cream or coconut milk. Make sure it is well mixed in. Taste the soup and adjust the seasoning with salt and pepper if needed. Allow the soup to cool slightly before serving. This helps enhance the flavors. Serve it hot in bowls, garnished with chopped chives. They add color and freshness to your dish.
Tips & Tricks
Sautéing vs. Slow Cooking Tips
Sautéing the leeks and onions adds depth. The heat wakes the flavors up. You can skip this step if time is tight. Just toss everything in the slow cooker. If you sauté first, cook for 5-7 minutes. This makes your soup richer and more fragrant.
Enhancing Flavor Profiles
Add sea salt and freshly cracked black pepper. These simple seasonings make a big difference. Try adding fresh herbs like thyme or chives. Fresh herbs boost the soup’s taste. You can also stir in a dash of lemon juice before serving. This adds brightness to the dish.
Texture Variations
For a creamy texture, blend the soup until smooth. If you like some chunks, blend only half. This gives a nice contrast in texture. You can also add a few crispy croutons on top. They add crunch and make the dish more fun to eat.

Variations
Dairy-Free Option with Coconut Milk
You can make this soup dairy-free by using coconut milk. It adds a creamy texture and a hint of sweetness. Replace the heavy cream with one cup of coconut milk. This option is great for those who are lactose intolerant or prefer plant-based meals. The flavor remains rich, and you still get that comforting mouthfeel.
Adding Protein to the Soup
If you want to make the soup heartier, add protein. You can stir in cooked bacon, sausage, or chicken. For a vegetarian option, mix in white beans or lentils. These choices bring in extra nutrients and make the dish more filling. Just add the protein during the last 30 minutes of cooking to heat it through.
Spice Infusions and Herb Swaps
Get creative with spices and herbs to change up the flavor. You can add a pinch of cayenne pepper for heat or smoked paprika for a smoky touch. Fresh herbs like dill, parsley, or rosemary can replace dried thyme. Just remember to adjust the amounts, as fresh herbs are more potent. These swaps give your soup a unique twist with every batch you make!
Storage Info
Storing Leftovers Properly
After enjoying your delicious potato leek soup, it’s key to store leftovers right. Let the soup cool down first. Then, transfer it into an airtight container. This helps keep the flavors fresh. You can store it in the fridge for up to five days. Be sure to label the container with the date. This way, you know when it was made.
Reheating Instructions
When you want to enjoy the soup again, reheating is easy. Pour the soup into a pot over medium heat. Stir it often to heat it evenly. If the soup seems thick, add a splash of vegetable broth or water. You can also use the microwave. Place the soup in a microwave-safe bowl. Heat it in short bursts, about one minute at a time. Stir in between each burst until it’s hot enough.
Freezing for Future Meals
Freezing potato leek soup is a great way to save some for later. Use freezer-safe containers or bags. Leave some space at the top of the container. Soup can expand when frozen. It stays good for up to three months. When you’re ready to eat it, move it to the fridge overnight to thaw. You can also reheat it straight from the freezer, just add a few extra minutes to the cooking time.
