Ingredients Needed
This wild mushroom soup recipe uses straightforward, wholesome ingredients for a deep, complex flavor. Most of these are pantry staples, and you can find wild mushrooms at most grocery stores or farmer’s markets (or use a mix of fresh and dried).
- For the Soup Base:
- 2 tablespoons olive oil (for sautéing)
- 2 tablespoons unsalted butter (adds richness; use vegan butter if needed)
- 2 large yellow onions, thinly sliced (caramelizes beautifully for sweetness)
- 4 garlic cloves, minced (for savory depth)
- 1 teaspoon salt, plus more to taste
- 1/2 teaspoon freshly ground black pepper
- 1/2 teaspoon dried thyme (or 1 teaspoon fresh thyme leaves, if you have them)
- For the Mushrooms:
- 1 pound (450g) mixed wild mushrooms, cleaned and sliced (shiitake, cremini, oyster, chanterelle—use what you find or even baby bella in a pinch)
- Optional: 1/2 ounce (14g) dried porcini or morels, soaked in 1 cup (240ml) hot water, liquid reserved (for even more umami—highly recommended!)
- For the Greens:
- 4 cups (about 120g) curly kale, ribs removed and leaves roughly chopped
- For the Broth:
- 6 cups (1.4L) low-sodium vegetable broth (use homemade if you have it—store-bought works just fine)
- Optional: 1/4 cup (60ml) dry sherry or white wine (adds a lovely tang; totally optional)
- To Finish:
- 1/4 cup (60ml) heavy cream or coconut cream (optional, for extra richness)
- 2 tablespoons chopped fresh parsley (for garnish)
- Fresh cracked black pepper, to taste
Ingredient Tips: I usually go for a mix of mushrooms—shiitake and cremini for depth, oyster mushrooms for their delicate flavor. If you can get dried porcini, don’t skip them! They add a real punch. For the broth, Better Than Bouillon is my go-to if I’m not using homemade. And honestly, don’t stress if you only have curly kale—lacinato works, too. For gluten-free needs, just double-check your broth label.
Equipment Needed
- Large Heavy-Bottomed Pot or Dutch Oven: Essential for even cooking and caramelizing onions. My trusty enameled Dutch oven never lets me down here—stainless steel works just as well.
- Wooden Spoon or Silicone Spatula: Great for stirring without damaging your pot. If the onions start sticking, a wooden spoon helps scrape up all that flavor.
- Sharp Chef’s Knife: For all the veggie prep. Seriously, makes a difference—dull knives are no fun.
- Cutting Board: I recommend a big one to handle all the mushrooms and kale.
- Measuring Cups and Spoons: For accuracy, especially with broth and seasonings.
- Ladle: For serving (and sneaking taste tests straight from the pot—guilty as charged!).
- Small Bowl (if using dried mushrooms): For soaking and reserving the soaking liquid.
If you don’t have a Dutch oven, a big soup pot is totally fine. You can also use a deep sauté pan in a pinch—just keep an eye on splatters. For budget-friendly options, IKEA and Target have decent heavy-bottomed pots. Pro tip: let your pot cool before scrubbing to keep it in good shape. And if you’re using nonstick, don’t use metal tools—they’ll scratch!
Preparation Method
- Prep the mushrooms and kale:
Wipe the mushrooms clean with a damp paper towel—don’t wash under water, or they’ll get soggy. Slice thick mushrooms and chop any big ones into bite-sized pieces. Remove kale ribs and roughly chop the leaves. If using dried mushrooms, soak them in 1 cup (240ml) hot water for 20 minutes, then drain (reserve the soaking liquid!). - Caramelize the onions (20–25 min):
Heat 2 tablespoons olive oil and 2 tablespoons butter in a large heavy-bottomed pot over medium-low heat. Add the sliced onions and 1 teaspoon salt. Stir every few minutes, scraping up any fond (browned bits) from the bottom. After 10 minutes, lower the heat if they’re browning too fast. The onions should become deep golden brown and very soft. (Don’t rush—this is where all the flavor happens!) - Add garlic and thyme (2 min):
Stir in the minced garlic and thyme. Cook, stirring, for about 2 minutes until fragrant. If you want a little extra depth, you can add a splash of wine at this point and let it cook off. - Sauté the mushrooms (8–10 min):
Toss in all your prepared mushrooms (fresh and, if using, soaked dried mushrooms). Cook over medium heat, stirring occasionally, until they soften and release their juices. The mushrooms will shrink and turn a nice golden color. If they start sticking, add a splash of broth. - Deglaze and simmer (15 min):
If using, pour in 1/4 cup (60ml) dry sherry or white wine. Let it bubble for a minute, scraping up any bits off the bottom. Add the reserved mushroom soaking liquid (if using), 6 cups (1.4L) vegetable broth, and black pepper. Bring to a boil, then reduce heat and let simmer uncovered for about 15 minutes. Taste and adjust seasoning (I usually add a pinch more salt here). - Add the kale (5 min):
Stir in the chopped kale. Simmer for 5 minutes, just until the kale is bright green and tender but not mushy. (Taste a piece—should still have a little bite!) - Finish and serve:
Turn off the heat. For extra creaminess, swirl in 1/4 cup (60ml) cream or coconut cream. Ladle into bowls and sprinkle with fresh parsley and black pepper. Serve hot—with crusty bread, if you ask me!
Troubleshooting Tips: If your onions burn, scrape out any black bits and lower the heat. Mushrooms too watery? Just keep cooking until most of the liquid evaporates. Soup too thick? Add a splash more broth. Soup too thin? Simmer uncovered for a bit longer. I always taste as I go and adjust—I promise, you’ll get a feel for it fast.
Cooking Tips & Techniques
- Go slow with the onions: Caramelizing onions takes patience. Medium-low heat and frequent stirring are key. Rushing this step can make them bitter instead of sweet.
- Use a mushroom mix: Different mushrooms cook at different rates and bring their own flavors. I love combining shiitake, oyster, and cremini for a balanced taste.
- Don’t drown the mushrooms: If you add them all at once, the pan can get crowded and they’ll steam instead of brown. If you have a smaller pot, add half at a time, let them cook down, then add the rest.
- Deglaze for flavor: Scraping up the browned bits with wine or broth adds tons of umami. Don’t skip this, even if you’re just using broth!
- Season as you go: The broth and mushrooms can be salty or bland—taste after each addition and adjust. I learned this the hard way when I over-salted once (yep, had to start over!).
- Make it creamy or keep it clear: Sometimes I skip the cream for a lighter soup, and sometimes I go all in for that silky finish. Both are delicious—just depends on your mood.
Avoid the temptation to crank up the heat—especially when caramelizing. And if you want to multitask, prep your mushrooms and kale while the onions cook. For consistency, cut your mushrooms roughly the same size. I’ve had the most success with homemade broth, but a good store-bought veggie broth works just fine if you doctor it up with extra herbs and garlic. Trust your senses: if it smells amazing, you’re on the right track!
Variations & Adaptations
- Vegan Wild Mushroom Soup: Use olive oil instead of butter and skip the cream. A splash of coconut cream or unsweetened oat milk at the end adds richness without dairy!
- Gluten-Free Option: This recipe is naturally gluten-free—just double-check your veggie broth label for hidden wheat ingredients.
- Seasonal Swaps: Try Swiss chard or spinach instead of kale in the spring. In autumn, add a peeled, diced sweet potato with the mushrooms for a slightly sweet twist.
- Different Cooking Methods: Make it in a slow cooker! Caramelize onions and sauté mushrooms as usual, then transfer everything to the slow cooker with broth and let it go on low for 4–6 hours. Add kale at the end.
- For a Thicker Soup: Blend half the soup with an immersion blender before adding the kale. It’s creamier and extra cozy.
- Personal Favorite: Sometimes I add a handful of cooked farro or brown rice at the end for more body. It soaks up the broth and makes the soup extra hearty.
- Allergen Substitutions: Nut allergy? No problem—just use coconut or oat milk for creaminess. Soy allergy? Stick to veggie broth and skip any soy-based creams.
It’s honestly fun to play around with this soup. If you have picky eaters, chop the kale smaller or blend the whole thing for a smoother texture. You can make it spicy with a pinch of red pepper flakes or add a squeeze of lemon juice for brightness. Let your taste buds guide you!
Serving & Storage Suggestions
This wild mushroom soup recipe is best served piping hot. I love ladling it into big bowls and topping with extra fresh parsley and a grind of black pepper. If you want to get fancy, a drizzle of olive oil or a sprinkle of grated Parmesan is never a bad idea. Pair it with crusty sourdough, a cheesy toast, or even a simple green salad for a full meal. For drinks, a glass of dry white wine or a rich stout complements the earthiness beautifully.
Leftovers keep really well! Let the soup cool completely, then transfer to airtight containers and refrigerate for up to 4 days. The flavors deepen after a day—honestly, it’s even better on day two. For longer storage, freeze in individual portions (leave a little space for expansion) for up to 3 months. To reheat, warm gently on the stove over medium-low heat, adding a splash of broth if it’s too thick. Microwave works too—just stir halfway through. The kale holds up surprisingly well, but if you want it super vibrant, add fresh kale when reheating.
