Main Ingredients for Slow Cooker Garlic Herb Mushrooms

Each ingredient in this recipe works together to create a rich, savory side dish that’s perfect for pairing with just about anything:

  • Button or Cremini Mushrooms (1 pound, whole or halved): These mushrooms are tender and flavorful when cooked, and their natural earthiness pairs perfectly with the garlic and herbs.
    • You can use white button mushrooms or baby bella (cremini) mushrooms, depending on your preference.
  • Butter (4 tablespoons, unsalted): Butter creates a rich base for the sauce, infusing the mushrooms with flavor as they cook.
    • You can substitute with olive oil for a dairy-free version.
  • Garlic (4 cloves, minced): Garlic adds a bold, savory flavor that enhances the earthiness of the mushrooms.
  • Fresh Herbs (2 tablespoons, chopped): A combination of parsley, thyme, and rosemary adds freshness and aromatic flavor to the dish.
    • You can use dried herbs if fresh isn’t available, but fresh herbs give the best flavor.
  • Balsamic Vinegar (1 tablespoon): Adds a touch of tanginess and sweetness to balance the richness of the butter and garlic.
  • Salt and Pepper (to taste): Enhances the flavors of the mushrooms and herbs.

Benefits of Ingredients

  • Mushrooms are low in calories but high in nutrients like vitamins B and D, antioxidants, and fiber.
  • Garlic has immune-boosting properties and adds a rich depth of flavor to the dish.

How to Make Slow Cooker Garlic Herb Mushrooms: Step-by-Step Instructions

  1. Prepare the Mushrooms: If the mushrooms are large, cut them in half. Smaller mushrooms can be left whole. Place the prepared mushrooms in the slow cooker.
  2. Make the Garlic Herb Butter: In a small saucepan, melt the butter over medium heat. Add the minced garlic and cook for 1-2 minutes, until fragrant. Remove from heat and stir in the chopped herbs and balsamic vinegar.
    • Be careful not to burn the garlic—it should be fragrant but not browned.
  3. Combine and Cook: Pour the garlic herb butter mixture over the mushrooms in the slow cooker. Season with salt and pepper, then toss to coat the mushrooms evenly in the sauce. Cover and cook on low for 3-4 hours or on high for 1-2 hours, until the mushrooms are tender and flavorful.
    • Stir the mushrooms halfway through cooking to ensure they cook evenly.
  4. Serve: Once the mushrooms are tender and fully cooked, transfer them to a serving dish and drizzle any remaining garlic herb sauce from the slow cooker over the top. Garnish with extra fresh herbs if desired, and serve warm.
    • These mushrooms are perfect as a side dish or served over steak, chicken, or even pasta.

Tips for Perfect Garlic Herb Mushrooms

  • Don’t Overcook: Mushrooms release moisture as they cook, so be careful not to overcook them, or they could become too soft. Cooking on low heat for 3-4 hours ensures they stay tender without getting mushy.
  • Use Fresh Herbs: While dried herbs work in a pinch, fresh herbs give the dish a brighter, more aromatic flavor.
  • Adjust Seasoning: Taste the mushrooms before serving and adjust the seasoning as needed. You can add more salt, pepper, or a splash of balsamic vinegar for extra flavor.
