Mushroom Soup Ingredients

  • Olive oil – Will be used for sautéing. You can use other vegetable-based oils that you have.
  • Aromatics – We used 3 garlic cloves and a cup of diced yellow onion for a savory base. You can also use red onion if that is what you have.
  • White or button mushrooms – These earthy and tender goodies give the soup a great umami flavor and wonderful texture.
  • Your choice of pasta –  Aany small pasta shape will do just fine. You can use orzo, tubetttini, macaroni, ditalini or orecchiette.
  • Herbs -We used bay leaf, dried rosemary, and dried marjoram for this recipe. They add mild minty, peppery, and floral tones to the soup, making it super flavorful! If you’re looking for ways to keep your herbs fresh, check out this article!
  • Vegetable broth – Use low-sodium broth for best results. You can also use water if you do not have broth.
  • Sea salt and ground black pepper – To taste. Add more if desired.
  • Kale leaves – Thinly sliced to add more flavor and texture to the soup. You can also use arugula, oregano, mustard greens, spinach, or collard greens as a substitute.

Cooking Tips For You!

  • Do not soak your fresh mushrooms in water when cleaning them, for they will absorb the liquid like crazy, and you will have a difficult time browning them. It is best to place them in a colander then quickly rinse them in running water. Or just use a clean wet cloth to wipe them clean.
  • It’s important to serve this soup immediately after it’s made because the pasta will soak up quite a bit of liquid if it sits around too long.
  • Do not overcook your pasta, or they will turn mushy. Follow package instructions for cooking time. Make sure to start checking on the pasta 2 minutes prior. It should be chewy yet still a bit firm.
  • Add a bit of spiciness to your soup by using a pinch or two of red pepper flakes or chili powder.

  1. Can I use other vegetables? Of course, you can! This is a great soup to make use of those leftover veggies in your chiller. Just make sure to cut them uniformly and always add the hardest veggies first and the soft ones last.
  2. Can I use other mushrooms? Sure, you can use baby bella, cremini, or shiitake.
  3. What other herbs can I use? It depends on what you like! Thyme, parsley, basil, dill, or Italian seasoning are great options!

Storing Notes

This soup is best served right away, as it really thickens and loses liquid the longer it sits. In case of any leftovers, you can always store them in a lidded container and refrigerate them for 3 to 5 days or freeze it for a month. The pasta will bloat up, so you will need to add more liquid as you reheat the soup.

    1. You can add whichever pasta you see fit! They have awesome chickpea and lentil pasta that you might like!

  1. 5 stars
    I have made this soup three times, each time with different frozen vegetables. It turns out delicious every time! I found the kale gets too limp, so instead i throw in a bag of frozen broccoli, peas, carrots, or whatever frozen veggies you like, it turns out amazing, specially with the mushrooms and elbow macaroni! You definitely want to add the pinch of red pepper flakes, it gives this soup a kick! This is my new go-to soup recipe!

      1. I haven’t tried this recipe yet but when I do a recipe like this, I had the kale at last minute just before turning the heat off. It’s just enough to welt it a bit and it’s perfect
