How to Make Crock Pot Cream of Mushroom Soup
Start by washing and removing the stems from the mushrooms. Save the stems for later. I used button mushrooms, but you can use any kind of edible mushroom!
Slice the mushroom caps and dice the stems and onion together. Saute the mushrooms and onion for roughly 3-5 mins or until tender. Then add it all to the slow cooker, aka Crock Pot.
Dice up some fresh rosemary leaves so they are same size as the thyme leaf. Then, add the rosemary and thyme mix to the slow cooker.
Mix the vegetable base and water together in a bowl and add to the slow cooker.
Pour in the cornstarch, salt, pepper, bay leaf and heavy cream. Give it a stir and add the lid. Slow cook in the Crock Pot on high for 4 hours. Then stir and serve! Garnish with fresh basil or parsley.
If you desire, you can simmer the recipe on the stove instead.
