The Star Ingredients: Mushrooms and Buckwheat

In this rich and flavorful soup, it’s truly a dance between two incredible ingredients vying for the spotlight: mushrooms and buckwheat. While they each bring unique qualities, their combined presence creates a symphony of savory, nutty, and earthy notes that defines this dish.

A Closer Look at Buckwheat

Buckwheat, often mistaken for a grain, is actually a gluten-free pseudocereal, related to rhubarb. It’s experiencing a well-deserved revival, and we couldn’t be more thrilled to feature it. Historically, buckwheat has been a cornerstone in various cuisines, particularly in Eastern Europe and Japan, where it’s cherished for its nutritional value and distinctive flavor. Unfortunately, its popularity waned in many other regions, only to be rediscovered for its incredible versatility and health benefits.

For this recipe, we specifically use **buckwheat groats**, which are the hulled seeds of the buckwheat plant, left whole. We opt for the **roasted variety**, often referred to as kasha, recognizable by its light brown color and firmer texture compared to unroasted groats. Roasting imparts a deeper, more pronounced nutty flavor that adds remarkable depth and earthiness to the soup. This natural savoriness makes buckwheat an ideal pairing for hearty vegetables and, of course, mushrooms.

The Magic of Mushrooms

Mushrooms are truly celebrated in this soup, with two distinct types working in harmony to deliver an unparalleled umami experience. The key to unlocking profound flavor here lies in the inclusion of **dried porcini mushrooms**. These humble dried fungi are culinary treasures, boasting an intensely concentrated earthy and woody flavor that fresh mushrooms simply can’t match. When rehydrated, they release a potent aroma and a rich liquid that forms the backbone of our flavorful broth, adding an extra layer of depth to the entire soup.

Alongside the porcini, we incorporate **fresh button mushrooms** (or your preferred variety). When sautéed until golden brown, these fresh mushrooms develop a beautiful caramelized exterior and a richer, meatier flavor, contributing to the overall heartiness and texture of the soup. The combination of dried porcini and fresh mushrooms ensures a multi-dimensional mushroom essence that truly shines.

Essential Vegetables & Flavor Enhancers

Beyond our star duo, a supporting cast of vegetables and aromatic ingredients builds the robust flavor profile of this soup. Onions and carrots form the aromatic base, slowly sautéed to release their sweetness and fundamental flavors. Fresh garlic adds its pungent warmth, complementing the earthiness of the mushrooms. And finally, vibrant kale is stirred in towards the end, providing a touch of color, a slightly bitter counterpoint, and a boost of nutrients. Together with a high-quality vegetable stock, these ingredients create a wholesome and incredibly flavorful broth that ties the entire dish together, making it a truly balanced and deeply satisfying meal.

Expert Tips for the Perfect Bowl

  • Don’t Skip the Dried Porcini: Dried porcini mushrooms are a secret weapon in this recipe. Their intense, concentrated umami flavor is irreplaceable and significantly enhances the depth of the soup. If they’re not readily available in your local grocery store, you can often find them online or in specialty food shops. Once purchased, they last indefinitely when stored in an airtight container, making them a pantry essential for elevating savory dishes.
  • Mushroom Variety Matters: While button mushrooms are a great choice for their mild flavor and firm texture, feel free to experiment with other mushroom varieties. Chanterelles will add a delicate, fruity note, oyster mushrooms offer a tender, slightly chewy texture, and cremini (baby bellas) provide a richer, earthier taste than white buttons. A mix of several types can add even more complexity.
  • Roasted vs. Unroasted Buckwheat: This recipe calls for roasted buckwheat groats, which have a distinctive nutty flavor and a firmer texture that holds up well in soup. If you can only find unroasted (light green) buckwheat, it will work, but the flavor will be milder and the texture softer. You can lightly toast unroasted buckwheat in a dry pan for a few minutes before adding it to the soup to enhance its nuttiness.
  • Grain Alternatives: If buckwheat isn’t to your liking or you’re looking for an alternative, several other grains can be used. Pearl barley will give the soup a slightly chewy, satisfying consistency. Wild rice offers a firmer bite and a distinct earthy aroma. Brown rice is another excellent option for added fiber and a hearty texture. Remember to adjust the cooking time according to the specific grain’s package instructions, as some may take longer than buckwheat.
  • Greens Swaps: Kale adds a beautiful color and slight bitterness to the soup, but spinach is a fantastic substitute. If using fresh spinach, add it in the last few minutes of cooking until it wilts. Frozen spinach can also be used; simply thaw and squeeze out excess water before adding.
  • Broth Choice: We’ve specifically used vegetable stock to keep this recipe vegan and vegetarian-friendly, ensuring its broad appeal. However, if you’re not adhering to a plant-based diet, chicken stock can be used for a different flavor profile. The key is to use a good quality stock for the best results.
  • Creaminess and Seasoning: For an extra layer of indulgence, you can stir in a splash of vegan cream (such as cashew cream or oat cream) or a swirl of dairy cream/sour cream (if not strictly vegan) just before serving. Always taste and adjust the salt and black pepper to your preference. A pinch of fresh thyme or rosemary can also elevate the aroma.

Serving Suggestions for Your Mushroom & Buckwheat Soup

This Hearty Vegan Mushroom and Buckwheat Soup is wonderfully satisfying on its own, but pairing it with the right accompaniments can elevate your meal to an extraordinary experience. Here are some delightful suggestions to complement its rich flavors:

  • Crusty Bread: A thick slice of warm, crusty bread is the quintessential companion for any hearty soup. Whether it’s a rustic farmhouse loaf, a tangy sourdough, or a savory focaccia, it’s perfect for soaking up every last drop of the flavorful broth. For a gluten-free option, ensure your chosen bread is certified gluten-free.
  • Grilled Sandwiches or Paninis: Transform your soup into a truly complete meal by serving it alongside a gourmet grilled sandwich. A chickpea salad sandwich makes for a fantastic vegan pairing, while a classic ham and cheese toastie or a sophisticated goat cheese sandwich with roasted vegetables would also be delicious choices.
  • Fresh Green Salad: A light, crisp green salad with a zesty vinaigrette provides a refreshing contrast to the richness of the soup. It adds a vibrant element and balances the meal beautifully.
  • Savory Muffins or Biscuits: Serve warm, homemade savory muffins or flaky biscuits on the side. They add a comforting, home-style touch and are perfect for dipping.
  • Garnish Galore: Elevate your soup with a fresh garnish. A sprinkle of fresh parsley or dill adds brightness. A dollop of vegan sour cream or a swirl of high-quality olive oil can add richness. Toasted pumpkin seeds or croutons provide a delightful crunch.
  • Beverage Pairing: A robust red wine like a Pinot Noir or a light-bodied Ale can complement the earthy flavors of the mushrooms and buckwheat. For a non-alcoholic option, iced green tea or sparkling water with a hint of lemon would be refreshing.

Storage & Make-Ahead Tips

One of the many beauties of this Vegan Mushroom and Buckwheat Soup is how wonderfully it lends itself to batch cooking and meal preparation. Making a larger quantity ensures you have nutritious, flavorful meals ready to go, saving you time and effort during busy weeks.

  • Refrigeration: Allow any leftover soup to cool completely to room temperature before transferring it to an airtight container. Properly stored, the soup will keep beautifully in the refrigerator for up to 5-7 days. The flavors often deepen and meld overnight, making it even more delicious the next day.
  • Freezing: This soup freezes exceptionally well. Once cooled, ladle individual portions into freezer-safe containers or heavy-duty freezer bags, leaving a little headspace for expansion. It can be stored in the freezer for up to 2-3 months without significant loss of quality. Label your containers with the date to keep track.
  • Reheating:
    • From the refrigerator: Reheat individual servings gently on the stovetop over medium-low heat, stirring occasionally, until warmed through. Alternatively, microwave in short intervals, stirring between each, until hot. You may need to add a splash of vegetable stock or water if the soup has thickened too much.
    • From the freezer: For best results, thaw frozen soup overnight in the refrigerator. Then, reheat as you would refrigerated soup. If reheating from frozen, you can do so on the stovetop over low heat, stirring frequently and breaking up any ice, until it has thawed and is simmering gently.
  • Flavor Freshen-Up: When reheating, taste the soup and adjust seasonings if necessary. A squeeze of lemon juice or a sprinkle of fresh herbs can help brighten the flavors after storage.

Embrace the convenience of batch cooking this nourishing soup. It’s perfect for those busy days when you crave a wholesome, homemade meal without the fuss.

A thick and warming winter soup packed full of nutritious ingredients and a flavoursome broth.

Ingredients

  • 1 tbsp olive oil
  • 1 onion
  • 1 carrot
  • 22g / 1/4 cup dried porcini or mixed mushrooms
  • 1 tbsp butter
  • 300g / 2½ cups button mushrooms
  • 1-2 cloves garlic
  • 85g / 1/2 cup roasted buckwheat groats, or pearl barley
  • 1½ litres / 6 cups vegetable stock
  • 1 tsp soup seasoning mix of your choice
  • salt to taste
  • 3 leaves kale, stalk removed

Instructions

  1. Soak the dried porcini mushrooms in 1 cup/250 ml boiling water for 30 minutes. Dice the carrot and chop the onion. Slice the fresh mushrooms and set aside till needed.
  2. In a medium pot, heat the olive oil and sauté the onion and carrot for 7-10 minutes over low heat until softened. Then add the sliced fresh mushrooms, 1 tbsp of butter and a pinch of salt. Increase the heat to medium and cook the mushrooms until they are golden brown on the outside. This browning process is crucial as it deeply contributes to the flavor of your soup. Finally, add the minced garlic and cook for another minute until fragrant.
  3. While the mushrooms are cooking, carefully remove the rehydrated dry porcini mushrooms from their soaking liquid, reserving the liquid. Strain the reserved liquid through a fine-mesh sieve or coffee filter to remove any sediment. Finely chop the rehydrated porcini mushrooms and add them to the pot along with the vegetable stock and the strained porcini liquid. Stir in the roasted buckwheat groats (or barley) and your chosen soup seasoning mix. Bring the soup to a boil, then reduce the heat to a simmer and cook for 15 minutes, or 25 minutes if using pearl barley. Add the chopped kale and continue to cook for an additional 5 minutes, or until the kale is tender-crisp. Taste and add more salt as needed before serving hot.
