Creamy Onion Mushroom Soup

Fall is officially here! It’s time to whip up some of my favorite vegetable soups from scratch made from real ingredients. On this particular day I was craving onions and mushrooms, which I conveniently had these two items in my kitchen. I had never made onion and mushroom soup before so I was giving it a test try and… oh… my… gah, it was delish! This will definitely be another one of my staple soups as a go to. Let’s get right to it.

Serving size: 2 | Prep Time: 5-7 minutes | Cook Time: 45 minutes – 1 hour


Kitchen Essentials:


  1. Peel and cut the onions into small thin slices on a cutting board and set aside in a mixing bowl.
  2. Rinse and slice the mushrooms into small slices on a cutting board and set aside in a mixing bowl.
  3. Place the sliced onions in a medium saucepan over medium heat and cover with lid. Occasionally stir with a wooden spoon until the onions are caramelized in a golden brown color, which may take about 10-15 minutes. Once caramelized, set aside in a mixing bowl.
  4. Next in the same saucepan, place the mushrooms and cover with lid to cook. Occasionally stir for about 5-7 minutes or until soft.
  5. Add the caramelized onions to the mushrooms in the saucepan and give it a quick stir.
  6. Add water just enough to be at the same level or barely submerge the onion and mushrooms. Bring it to simmer and turn off the heat.
  7. Pour the contents from the saucepan into a blender. Using the soup setting, blend the contents until smooth. (Be very careful, it’s very hot! Be sure to hold the blender lid while blending for that extra precaution.)
  8. Pour the soup back into the saucepan over no heat. Add salt, thyme, and dill and give it a quick stir.
  9. Serve the soup using a ladle.

This Creamy Onion Mushroom Soup is great side to eat with buttered baguettes, bruschettas, or even a side salad.
