  • 24 ounces cremini mushrooms
  • 4 garlic cloves minced
  • 1 teaspoon dried oregano
  • 1 teaspoon dried Basil
  • 1/2 teaspoon dried thyme
  • 3/4 cup vegetable broth
  • Salt and pepper to taste
  • 4 tablespoons unsalted butter
  • Fresh parsley for garnishing


  • Place all the ingredients except the butter and parsley in a 4-qt slow cooker. Stir to combine.
  • Cook the mushrooms on high for 1-2 hours or low for 2-3 hours, until mushrooms are tender.
  • Place the butter in the slow cooker during the last 15 minutes. Garnish with chopped parsley before serving.


  • I use baby Bella (also known as cremini) mushrooms for this recipe for their deeper and meatier flavor. However, white button mushrooms will also work.
  • Lots of liquid will release in the slow cooker while the mushrooms cook. Serve with a slotted spoon (or not).
