This slow cooker version of chicken stroganoff delivers the same creamy indulgence as the classic without the stovetop babysitting. I developed this method after too many rushed weeknights when takeout seemed like the only option.
The beauty lies in letting the slow cooker do the work. Chicken thighs stay tender, mushrooms absorb rich flavors, and the sauce develops depth over hours of gentle cooking. The sour cream finishes it with that signature tangy richness.
What emerges is a sauce so velvety it clings to every egg noodle, with chicken that falls apart at the touch of a fork. It’s the kind of meal that makes you question why you ever bothered with the stovetop version.
Perfect for busy days when you want restaurant-quality results with minimal effort.
Ingredients for Slow Cooker Chicken Stroganoff Recipe with Sour Cream
Rich sauce, tender chicken, and earthy mushrooms come together for this hands-free comfort classic.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless Skinless Chicken Thighs 🍗 | 1 ½ lb | Trimmed of excess fat |
| Cremini Mushrooms 🍄 | 10 oz | Sliced, about 3 cups |
| Yellow Onion 🧅 | 1 whole | Medium, finely diced |
| Garlic Cloves 🧄 | 3 cloves | Minced for depth |
| Chicken Broth 💧 | 1 ½ cups | Low-sodium preferred |
| Worcestershire Sauce 🫒 | 1 tbsp | Adds umami richness |
| Dijon Mustard 🟡 | 2 tsp | Smooth, not grainy |
| Sour Cream 🥛 | 1 cup | Full-fat for creaminess |
| Egg Noodles 🍜 | 8 oz | Uncooked, wide or medium |
| All-Purpose Flour 🌾 | ¼ cup | For thickening sauce |
| Unsalted Butter 🧈 | 2 tbsp | Divided for cooking and finishing |
| Dried Thyme 🌿 | 1 tsp | Crushed for better flavor |
| Kosher Salt 🧂 | 1 tsp | Or to taste |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
The chicken thighs are key here—bone-in works too but boneless makes eating easier. Costco has great packs of thighs, or grab them from the butcher counter at Whole Foods. For mushrooms, cremini (baby bellas) have more flavor than white button. The broth matters—Better Than Bouillon or Swanson are solid choices. Don’t skip the Worcestershire; it’s the secret to that deep, savory base (just make sure it’s not the anchovy-free version).
No cremini mushrooms? White button or shiitake both work. Out of Dijon? Regular mustard at half the amount plus a pinch of sugar gets you close. Sour cream can be full-fat Greek yogurt for a tangier twist. Need this gluten-free? Swap the flour for cornstarch (use half the amount). Want extra richness? Stir in a splash of heavy cream at the end (trust me on this one).
This keeps beautifully—sauce thickens as it cools. Store in the fridge for up to 4 days or freeze for 3 months. Reheat gently to avoid curdling the sour cream. Leftovers taste even better the next day, once all the flavors meld together.

Step-by-Step Instructions for Slow Cooker Chicken Stroganoff With Sour Cream
This hands-free method delivers creamy, comforting perfection without the fuss.
Step 1: Sear and Season the Chicken Thighs
Heat 1 tablespoon unsalted butter in a large skillet over medium-high heat. While it melts, pat the 1.5 lb boneless skinless chicken thighs dry with paper towels and season both sides with 1 teaspoon kosher salt and 0.5 teaspoon black pepper.
Sear the chicken for 3-4 minutes per side until golden brown. You’re building flavor here, not cooking through. The chicken will finish in the slow cooker. Transfer the seared thighs to your slow cooker insert.
Step 2: Sauté the Aromatics and Mushrooms
In the same skillet, add the remaining 1 tablespoon unsalted butter. Add the 10 oz cremini mushrooms, 1 whole yellow onion, and 3 cloves garlic cloves. Cook for 5-6 minutes, stirring occasionally, until the mushrooms release their moisture and begin to brown.
Sprinkle the 0.25 cup all-purpose flour over the vegetables and stir for 1 minute to cook off the raw flour taste. This creates a roux that will thicken your sauce beautifully. Pour in 1.5 cups chicken broth, 1 tablespoon Worcestershire sauce, and 2 teaspoons Dijon mustard, scraping up any browned bits.
Step 3: Slow Cook Until Tender
Transfer the mushroom mixture to the slow cooker with the chicken. Add 1 teaspoon dried thyme. Cover and cook on low for 4-5 hours or high for 2-3 hours. You’ll know it’s ready when the chicken shreds easily with a fork.
About 30 minutes before serving, cook the 8 oz egg noodles according to package directions until al dente. Drain and set aside. This timing ensures everything finishes together.
Step 4: Finish with Sour Cream and Serve
Stir in the 1 cup sour cream into the slow cooker until fully incorporated. Taste and adjust seasoning if needed—the sauce should be rich and creamy with a slight tang from the sour cream.
Serve the creamy chicken and mushroom mixture over the cooked egg noodles. Garnish each serving with 0.25 cup fresh parsley for a pop of color and freshness. The sauce should cling beautifully to the noodles, with tender chicken and earthy mushrooms in every bite.
Pro Tips For Making Slow Cooker Chicken Stroganoff Recipe With Sour Cream
- Sear the Chicken: Brown the boneless skinless chicken thighs in a hot pan for 2-3 minutes per side before adding to the slow cooker. I learned this the hard way—without searing, the stroganoff tastes flat and misses that deep, savory base.
- Slice Mushrooms Thin: Cut the cremini mushrooms into ¼-inch slices so they soften evenly in the slow cooker. After ending up with rubbery chunks in my first few attempts, I now take the extra minute to slice them uniformly.
- Add Sour Cream Late: Stir in the sour cream only during the last 15 minutes of cooking to prevent curdling. My grandmother swore by this, and she was right: it keeps the sauce creamy and smooth every time.
- Use Room-Temp Broth: Take the chicken broth out of the fridge 20 minutes before starting, or microwave it for 30 seconds. Sounds weird, but it works—cold broth slows down the cooking time and can make the chicken tougher.
Storing and Reheating slow cooker chicken stroganoff recipe with sour cream
Refrigerator Storage
Let your stroganoff cool for no more than 2 hours before transferring to airtight containers—I use glass ones from New Seasons Market. Store at 40°F or below for up to 4 days. The flavors deepen overnight, making leftovers even more delicious. ❄️
Freezer Storage
This freezes beautifully for up to 3 months without texture loss. I recommend quart-size freezer bags—lay flat to save space. Leave 1 inch headspace for expansion and squeeze out excess air to prevent freezer burn.
Stovetop Reheating
Transfer to a saucepan and warm over medium-low heat for 8-10 minutes, stirring occasionally. Add ¼ cup chicken broth if the sauce thickens too much. This method preserves the creamy texture best.
Microwave Reheating
Cover with a damp paper towel and heat on 70% power in 1-minute intervals, stirring between each. Stop when it reaches 165°F. The sour cream may separate slightly, but stirring restores the creamy consistency. 🔥
Noodle Storage Tip
Store cooked noodles separately from the sauce to prevent them from absorbing too much liquid. When reheating, combine them and add a splash of broth to refresh. I learned this the hard way after a mushy batch!

Frequently Asked Questions
Can I use chicken breasts instead of thighs?
Yes, but they may dry out. Thighs stay juicier in slow cookers. If using breasts, reduce cook time to 2-3 hours on low and consider adding ¼ cup extra broth.
Why sear the chicken first?
Searing develops deep flavor through caramelization. It creates a fond (browned bits) that enriches the sauce. Skipping this step results in a blander dish.
Can I add the sour cream at the beginning?
No, sour cream can curdle with long cooking. Always stir it in during the last 30 minutes to maintain a smooth, creamy texture.
How can I make this gluten-free?
Replace the flour with 2 tablespoons cornstarch. Mix it with cold broth before adding to avoid lumps. Ensure your Worcestershire sauce is gluten-free too.
