- Salt and pepper to taste – season generously!
- 1 cup vegetable broth – the liquid base for our sauce
- 1 tablespoon soy sauce – for that crucial umami punch

- 2 tablespoons all-purpose flour – to thicken the sauce with the sour cream
- Fresh parsley, chopped, for garnish – adds a pop of freshness and color
How to Make Slow Cooker Mushroom Stroganoff
- Step 1: Before you do anything else, get your slow cooker ready by preheating your oven to 350°F (175°C). This step isn’t for the slow cooker itself, but for sautéing our delicious mushroom base. Grab a skillet and heat 1 tablespoon olive oil over medium heat. Add 1 onion, finely chopped, and 3 garlic cloves, minced. Sauté these until the onion is wonderfully translucent and smells amazing, about 5-7 minutes.
- Step 2: Now, toss in the star of the show: 1 pound mushrooms, sliced. Add 1 teaspoon dried thyme and 1 teaspoon paprika. Season generously with salt and pepper to taste. Cook this mixture, stirring occasionally, until the mushrooms are tender and have released their earthy juices, usually around 8-10 minutes. The aroma at this stage is just incredible!

- Step 3: Carefully transfer this sautéed mushroom goodness into your slow cooker insert. Pour in 1 cup vegetable broth and 1 tablespoon soy sauce. Give everything a good stir to combine all those beautiful flavors. This is where the magic of how to make slow cooker mushroom stroganoff really begins to unfold.
- Step 4: Cover your slow cooker and set it to cook on the low setting for 4–5 hours or on the high setting for 2–3 hours. The exact time will depend on your slow cooker, but you’re looking for the mushrooms to be super tender and the liquid to be flavorful.
- Step 5: Once the cooking time is almost up, it’s time to achieve that signature creamy texture. In a small bowl, whisk together 1/2 cup sour cream and 2 tablespoons all-purpose flour until you have a smooth paste. Stir this mixture into the slow cooker. Cook on high for an additional 30 minutes, or until the sauce has thickened beautifully. You’ll know it’s ready when it coats the back of a spoon. This is a crucial step in how to make slow cooker mushroom stroganoff perfectly creamy.
- Step 6: Ladle your warm, comforting Slow Cooker Mushroom Stroganoff over your favorite egg noodles or fluffy rice. Garnish with freshly chopped parsley for a burst of color and freshness. Enjoy this simple and delicious meal!
