Ingredients You’ll Need
For the Stroganoff Base:
- 2 tablespoons olive oil - 1 large yellow onion, chopped - 4 garlic cloves, minced - 1½ pounds mushrooms (baby bella, cremini, or a mix), sliced - 1 tablespoon soy sauce - 1 tablespoon Worcestershire sauce (use vegetarian version if needed) - 1 teaspoon paprika - 1 teaspoon dried thyme - 1½ cups vegetable broth - Salt and pepper to tasteTo Finish:
- 8 oz egg noodles (or pasta of choice) - 1 cup sour cream (or plain Greek yogurt) - 2 tablespoons all-purpose flour (optional, for thickening) - Fresh parsley, chopped (for garnish)How to Make Slow Cooker Mushroom Stroganoff
Step 1: Sauté the Aromatics (Optional but Recommended)
For deeper flavor, start by heating olive oil in a pan over medium heat. Sauté the onions for 5 minutes until translucent, then add garlic and cook for another minute. This step can be skipped if you're in a rush, but it builds flavor early on.
Step 2: Load the Slow Cooker
Add the sautéed onions and garlic to the slow cooker. Then add sliced mushrooms, soy sauce, Worcestershire sauce, paprika, thyme, broth, salt, and pepper. Stir everything together gently to combine.
Step 3: Slow Cook to Perfection
Set the slow cooker to low and cook for 6 to 7 hours, or on high for 3 to 4 hours. The mushrooms will shrink down and release their juices, creating a rich base.
Step 4: Cook the Noodles
About 20 minutes before serving, boil the egg noodles separately according to package instructions. Drain and set aside.
Step 5: Add the Creamy Finish
In the last 10–15 minutes of cooking, stir in the sour cream. If the sauce is too thin for your liking, dissolve the flour in a few tablespoons of water and stir it in to thicken. Taste and adjust seasoning as needed.
Step 6: Serve and Enjoy
Spoon the creamy mushroom mixture over the noodles or mix them into the slow cooker. Garnish with chopped parsley and serve hot.

FAQs: Mushroom Stroganoff in the Slow Cooker
Can I use canned mushrooms?
Fresh mushrooms are strongly recommended for the best texture and flavor. Canned mushrooms tend to be too soft and watery for this recipe.
Is it vegan?
Not by default, but it’s easy to make it vegan by using plant-based sour cream and skipping Worcestershire (or using a vegan version).
Can I add protein?
Absolutely. While it's satisfying as-is, you can stir in cooked lentils, chickpeas, or sautéed tofu cubes for added protein.
Can I cook the noodles in the slow cooker?
It’s best to cook noodles separately to avoid overcooking and mushy texture. Add them just before serving for best results.
