    Soup season is well and truly here, and if you are looking for a big bowl of comfort then you are in the right place! This rich and creamy mushroom and leek soup is easy to make in one pot with simple ingredients. It's wonderfully earthy, fresh and filling, and of course, topped off with some bacon!

    There have definitely been some warm days here in Toronto, but we know that the Canadian winter is just around the corner, so that has thrown me straight into a soup making frenzy!

    This delicious creamy mushroom and leek soup is the perfect way to combat the chilly weather. Quick to prep, be sure to make a big batch for the freezer and easy weeknight meals. This soup is really rich and earthy and it will warm you up from the inside out!

    Ingredients

    There's really nothing complicated for this recipe, simple ingredients and one tasty soup once you've done!

    • Bacon: To create a nice smoky flavor.
    • Garlic: Use freshly minced garlic for the best flavor.
    • Onion: Use a large white or yellow onion finly diced for an extra layer of flavor.
    • Salt and pepper: Adjusted to taste.
    • Mushrooms: I used a mix of white mushrooms and shitake for this recipe. Shitake have a rich and buttery flavor that work so well in soups. You can use any kinds of mushrooms you have to hand like portobellos or oyster.
    • Leeks: For that mild onion flavor. You can use all of the leek in this soup, the white and green parts.
    • Cream: Use heavy cream, also known as whipping or double cream, in this recipe for a really luxurious texture.
    • Chicken stock: You can use homemade or store bought stock.
    • Parsley: To garnish and add a freshness to the finished soup.

    Frequently Asked Questions

    Can you make this soup vegetarian?

    Yes, it's super easy to make this meat free. Simply omit the bacon, instead, cook the veggies in a tablespoon of oil or butter, and swap the chicken stock for vegetable stock or water.

    How long does it keep?

    This soup is great for easy lunches or mains throughout the week. After blending, let the soup cool to room temperature and transfer it to an airtight container. It will keep well in the fridge for 4 to 5 days. Reheat it on a medium heat on the stovetop, stirring occasionally until heated through.

    Can you freeze it?

    Yes! Soups are the king of freezer meals and will keep well up to 3 months. Defrost frozen soup in the fridge overnight before reheating. Because there is cream in this soup, give it a good stir before and during reheating it on a medium heat so that it doesn't separate.

    Recipe Notes and Tips

    • Use a dutch oven or heavy bottomed pan to make this soup. It will distribute the heat more evenly so that the bottom of the soup won't burn.
    • If you have a small pot, you may need to add the mushrooms in a couple of batches and cook them to shrink them in size.
    • I wanted to keep this soup as simple as possible, but feel free to add in some dried herbs or red chili flakes to give it an extra punch of flavor.
    • If you find that your soup is too thick when you reheat it, just stir in a little milk to loosen it up.
    • Taste the soup before serving and adjust the seasoning to suit your tastes.

    This soup is perfect on it's own and can be served as an appetizer or main. It's perfect with some crusty bread to mop up, or go full out and serve it with some cheesy garlic bread!

      Thank you for this, it was delicious! I had a few changes based on my available ingredients: 1 cup cauliflower, 1 cup mushrooms, 2 dried shiitake mushrooms (rehydrated and saved water), a few extra garlic cloves, 1tsp of Trader Joe's Mushroom & Company Umami Seasoning, just one cup of heavy cream. I was skeptical but it worked. Can't wait to try this with more mushrooms!

      Really lovely base recipe. I added sherry, thyme and paprika and went with 1/2 & 1/2 instead of heavy cream. The seasoning added some interest, and the reduced fat content made me feel slightly more virtuous… although I certainly lost some of the richness. Thanks for posting! I might add additional veggies next time.

        Hey Bridget, thanks for taking the time to comment! So glad you enjoyed this recipe, love the addition of thyme and paprika, and of course the sherry! Soups are great to add in your own twists and flavors!

      Personally I would sweat off the leeks first. A pinch of cayenne and a splash of dry sherry will go a long way and raise the bar.

        Hi Laurie, thanks for taking the time to comment! The leeks should be soft enough, but you can certainly add them to the pot sooner, with the onions. I wanted to make this super accessible, but I agree, a little sherry or white wine would elevate this really well!
