Meta Description
Discover the ultimate comfort food with this easy Slow Cooker Mushroom Stroganoff recipe. A creamy, savory vegetarian meal featuring earthy mushrooms and a rich garlic sauce, perfect for busy weeknights.
Ingredients
The Base:
- 2 lbs (900g) Cremini (baby bella) mushrooms, cleaned and halved (or quartered if very large)
- 1 medium Yellow onion, finely diced
- 4 cloves Garlic, minced
- 2 tbsp Soy sauce (adds a savory “umami” depth)
- 1 tbsp Worcestershire sauce (use a vegetarian version if preferred)
- 1 tsp Dried thyme
- 1/2 cup Vegetable broth
- Salt and black pepper to taste
The Creamy Finish: - 1 cup Full-fat sour cream (room temperature)
- 4 oz Cream cheese, softened and cubed
- 2 tbsp Cornstarch (whisked with 2 tbsp water to make a slurry)
- Fresh parsley, chopped (for garnish)
For Serving: - 12 oz Wide egg noodles (cooked separately)
Instructions
- Prep the Slow Cooker: Place the prepared mushrooms, diced onions, and minced garlic into the bottom of a 6-quart slow cooker.
- Season: Pour in the vegetable broth, soy sauce, Worcestershire sauce, and dried thyme. Toss gently to ensure the mushrooms are coated. Season with a pinch of salt and a generous amount of cracked black pepper.
- Slow Cook: Cover and cook on Low for 4–5 hours or on High for 2–3 hours. The mushrooms will release their own juices, creating a flavorful broth.
- Thicken the Sauce: About 30 minutes before serving, whisk the cornstarch slurry into the slow cooker. Stir in the cubed cream cheese. Cover and continue cooking on high until the cheese has melted and the sauce has thickened.
- The Final Fold: Turn the slow cooker to the “Keep Warm” setting or off. Gently fold in the sour cream until the sauce is smooth and silky. Avoid boiling the sauce once the sour cream is added to prevent curdling.
- Combine: Add the cooked egg noodles directly into the crockpot and toss to coat, or ladle the mushroom mixture over individual bowls of noodles. Garnish with fresh parsley.
Service Suggestions
- The Classic: Serve over buttery wide egg noodles or pappardelle pasta.
- Low Carb: Excellent over creamy mashed cauliflower or roasted spaghetti squash.
- The Sidekick: Pair with a crisp green salad and a side of crusty sourdough bread to soak up every drop of the sauce.
Storage Tips
- Refrigerate: Store leftovers in an airtight container for up to 3–4 days.
- Reheating: Reheat gently on the stovetop over low heat. If the sauce has thickened too much, add a splash of broth or milk to loosen it up.
- Freezing: This dish does not freeze well due to the high dairy content (sour cream and cream cheese), which tends to separate and become grainy when thawed.
FAQs
Can I use white button mushrooms?
Absolutely. While cremini mushrooms offer a deeper flavor, white button mushrooms work perfectly well and will still be delicious.
How do I prevent the sauce from being watery?
Mushrooms release a lot of liquid. If your sauce is too thin at the end, let it cook uncovered on the High setting for 20 minutes after adding the cornstarch slurry.
Is this recipe vegetarian?
It is, provided you use a vegetarian-friendly Worcestershire sauce (which omits anchovies) and vegetable broth.
