The Simple Ingredients
Look at this list! Most of this is probably in your kitchen right now. The “wild” mushrooms just add a fun, earthy boost. Use what you can find.
- 2 tbsp olive oil or butter
- 2 large yellow onions, thinly sliced
- 1 lb mixed wild mushrooms (like cremini, shiitake, oyster), cleaned and sliced
- 4 cloves garlic, minced
- 1 tsp dried thyme
- 1/4 cup dry white wine (or sub more broth)
- 6 cups vegetable or chicken broth
- 1 large bunch of kale, stems removed, leaves torn
- Salt and black pepper to taste
- Optional garnish: Grated Parmesan cheese, a drizzle of cream, or crusty bread
Let’s Get Cooking! (The Step-by-Step)
Grab your biggest soup pot or Dutch oven. We’re doing this in one dish for easy cleanup. Follow these steps and you cannot fail.
- Caramelize the onions. Heat the oil in your pot over medium-low heat. Add the sliced onions and a pinch of salt. Cook, stirring here and there, for 20-25 minutes until they’re golden brown and sweet. This is the flavor foundation. Be patient!
- Brown the mushrooms. Turn the heat up to medium-high. Add all the mushrooms to the pot with the onions. Don’t stir right away! Let them sit for 3-4 minutes to get a good, brown sear. Then stir and cook until they’ve released their water and are browned.
- Add the aromatics. Stir in the garlic and dried thyme. Cook for just one minute until fragrant. Pour in the white wine to scrape up any browned bits from the bottom of the pot. Let it bubble for a minute.
- Build the soup. Pour in the broth. Bring everything to a boil, then reduce to a steady simmer. Let it cook for 10 minutes to let the flavors marry.
- Wilt the kale. Add the torn kale leaves to the pot. Stir them in. They will wilt down in about 3-5 minutes. Taste the soup! Add salt and pepper until it’s perfect for you.
- Serve it hot. Ladle the soup into bowls. Add a sprinkle of Parmesan or a swirl of cream if you like. Don’t forget the bread for dipping!

Nutrition Information
A thick slice of crusty, toasted bread is non-negotiable. It’s perfect for soaking up the broth. A simple green salad with a vinaigrette adds a fresh crunch.
For a heartier dinner, add a protein. A can of drained white beans stirred in at the end is fantastic. A rotisserie chicken from the store is another quick win. For a different take on a rich, mushroom-based soup, this meatless mushroom and spinach lasagna soup is a fantastic option to try.
Make This Recipe Your Own (Quick Swaps)
Use what you have! This recipe is incredibly flexible. Don’t run to the store for one item.
No wild mushrooms? Use all cremini or even white button mushrooms. They work great. Don’t have kale? Spinach or Swiss chard are easy swaps. Just add spinach at the very end.
Not a wine person? Use an extra 1/4 cup of broth with a tiny splash of apple cider vinegar or lemon juice for acidity. Want it creamy? Stir in 1/2 cup of heavy cream or coconut milk at the end.
How to Store Leftovers (If You Have Any!)
This soup gets even better the next day. The flavors really settle in and get cozy.
Let the soup cool completely. Store it in an airtight container in the fridge. It will stay fresh for up to 4 days.
Reheat it gently on the stove over medium heat. You can also freeze this soup for up to 3 months. Thaw it overnight in the fridge before reheating.

FREQUENTLY ASKED QUESTIONS
Can I make this soup in a slow cooker?
Yes! Caramelize the onions and brown the mushrooms on the stove first for best flavor. Then transfer everything (except kale) to the slow cooker. Cook on LOW for 6-8 hours. Stir in the kale 30 minutes before serving.
My soup tastes a little flat. What can I do?
No problem! Brighten it up with a squeeze of fresh lemon juice at the end. Also, make sure you used enough salt. It makes all the other flavors pop.
What’s the best way to clean mushrooms?
Don’t soak them! Just wipe them with a damp paper towel or use a soft brush. If they’re very dirty, a quick rinse and immediate pat dry is fine.
