Beef stroganoff is one of those classic comfort dishes that always hits the spot, but standing over a hot skillet at the end of a long day is not always in the cards. This slow cooker version takes everything you love about the original, the fall-apart beef, the earthy mushrooms, the silky sour cream sauce, and lets the crockpot do the heavy lifting while you get on with your day.

The secret is a two-stage build: we sear the beef and mushrooms first to develop that deep golden-brown flavor, then let the slow cooker gently braise everything until the meat practically melts. A cornstarch slurry and a swirl of sour cream at the very end give you that thick, glossy sauce that clings to every noodle.
Serve it over buttered egg noodles, mashed potatoes, or even rice, and you have a hearty, crowd-pleasing dinner that tastes like you spent hours in the kitchen. It also reheats beautifully, making it a fantastic meal-prep option for busy weeks.
Why You'll Love This Recipe
About the Ingredients
2.5 lbs (1.13 kg) beef chuck roast, cut into 1-inch cubes
Chuck is ideal because its marbling breaks down during long cooking. You can substitute beef stew meat already cubed, or sirloin if you prefer a leaner, firmer bite.
2 tbsp (30 ml) vegetable oil
Use a neutral high-smoke-point oil for searing. Canola or avocado oil works equally well; avoid olive oil, which can smoke at high heat.
1 large yellow onion, diced (about 1.5 cups / 200g)
Yellow onion gives the best sweet-savory base. White onion is a fine substitute, or use frozen diced onion to save prep time.
12 oz (340 g) cremini mushrooms, sliced
Cremini (baby bella) mushrooms have more flavor than white buttons. If you can only find white mushrooms, add an extra splash of soy sauce for depth.
3 cloves garlic, minced (about 1 tbsp)
Fresh garlic is best, but 1 tsp garlic powder can stand in. Look for firm, heavy heads with tight papery skin when buying.
2 cups (480 ml) low-sodium beef broth
Low-sodium lets you control the salt level. Swap in vegetable broth or a cup of dry red wine plus 1 cup broth for a richer, more complex sauce.
2 tbsp (30 g) tomato paste
Tomato paste adds body and a subtle sweetness. If you only have ketchup, use 3 tbsp and reduce the salt slightly.
1 tbsp (15 ml) Worcestershire sauce
This adds umami depth. Soy sauce or coconut aminos make a good substitute if you are out of Worcestershire.
1 tbsp (8 g) cornstarch whisked into 2 tbsp (30 ml) cold water
Cornstarch thickens the sauce without flour lumps. Arrowroot powder or potato starch works as a 1:1 gluten-free swap.
1 cup (240 g) full-fat sour cream, at room temperature
Full-fat sour cream gives the creamiest result and resists curdling. Greek yogurt can substitute, but stir it in off the heat to avoid splitting.
1 tbsp (15 g) Dijon mustard
Dijon brings a gentle tang that balances the richness. Whole-grain mustard adds nice texture if you prefer.
12 oz (340 g) wide egg noodles, cooked, for serving
Egg noodles are the classic pairing. Serve over mashed potatoes, rice, or zucchini noodles for a lower-carb option.
Tips & Tricks
Sear in Batches
Crowding the pan steams the beef instead of browning it. Cook in two batches over medium-high heat (375F/190C) for 3 to 4 minutes per side until deeply golden.
Add Sour Cream Off the Heat
Boiling sour cream causes it to curdle and turn grainy. Stir it in only after the slow cooker is turned off and the stew has cooled for 2 minutes.
Thicken at the End
The sauce will look thin right after cooking. Whisk in the cornstarch slurry, cover, and cook on High for 10 to 15 minutes until it bubbles at the edges and coats a spoon.
Pro Tips
Step-by-Step Instructions
1. Sear the Beef
Pat the beef cubes dry and season generously with salt and pepper. Heat 1 tbsp oil in a large skillet over medium-high heat (375F/190C) and sear half the beef for 3 to 4 minutes per side until deeply golden brown, then transfer to the slow cooker. Repeat with the remaining oil and beef.
2. Brown the Mushrooms
Add the mushrooms to the same skillet and cook over medium-high heat (375F/190C) for 4 to 5 minutes, stirring occasionally, until golden and their moisture has evaporated. Transfer to the slow cooker.
3. Soften the Aromatics
Lower the heat to medium (350F/175C) and add the onion to the skillet, cooking for 4 minutes until translucent. Add the garlic and tomato paste and cook for 1 minute until fragrant and the paste darkens slightly.
4. Deglaze and Combine
Pour in the beef broth and Worcestershire sauce, scraping up any browned bits from the bottom of the pan. Pour everything into the slow cooker and stir to combine with the beef and mushrooms.
5. Slow Cook
Cover and cook on Low for 6 to 7 hours or on High for 3 to 4 hours, until the beef shreds easily with a fork and reaches an internal temperature of at least 200F (93C) for fall-apart tenderness.
6. Thicken the Sauce
Turn the slow cooker to High. Whisk the cornstarch slurry and stir it in along with the Dijon mustard. Cover and cook for 10 to 15 minutes until the sauce bubbles at the edges and thickly coats the back of a spoon.
7. Finish with Sour Cream
Turn off the slow cooker and let it sit for 2 minutes. Stir in the room-temperature sour cream until the sauce is smooth and creamy, then taste and adjust salt and pepper.
8. Serve
Ladle the stroganoff stew over hot buttered egg noodles and garnish with chopped fresh parsley if desired. Serve immediately.
Delicious Variations
Red Wine Mushroom
Replace 1 cup of the beef broth with dry red wine and add an extra cup of mushrooms for a deeper, more elegant sauce.
Creamy Paprika Stroganoff
Stir in 1 tsp smoked paprika with the tomato paste for a warm, smoky twist that pairs beautifully with mashed potatoes.
Lightened-Up Version
Use nonfat Greek yogurt in place of sour cream and serve over cauliflower rice to cut carbs and calories without losing creaminess.
How to Store Slow Cooker Beef Stroganoff Stew
Refrigerator
Store leftovers in an airtight container in the refrigerator for up to 4 days. Keep the noodles separate so they do not absorb all the sauce.
Freezer
Freeze the stew without the sour cream or noodles for up to 3 months. Thaw overnight in the refrigerator, reheat gently, then stir in fresh sour cream before serving.
Reheating
Reheat on the stovetop over low heat or in the microwave in 1-minute increments, stirring between each, until steaming hot. Add a splash of beef broth if the sauce has thickened too much.
Frequently Asked Questions
Q: Can I put raw beef in the slow cooker for stroganoff?
Yes, you can add raw cubed beef directly to the slow cooker, but searing it first gives a much deeper flavor and better texture. If you skip the sear, add 15 to 30 minutes to the cook time and use a fattier cut like chuck for the best results.
Q: Why did my slow cooker stroganoff curdle?
Your sour cream likely curdled because it was added while the stew was still boiling or because it was cold from the fridge. Always stir sour cream in after turning off the heat and let it come to room temperature first for a smooth, lump-free sauce.
Q: Can I make beef stroganoff stew in the Instant Pot instead?
Yes, sear the beef and mushrooms using the saute function, then pressure cook on High for 25 minutes with a 10-minute natural release. Thicken with the cornstarch slurry on saute mode and stir in the sour cream off the heat.
Q: What is the best cut of beef for slow cooker stroganoff?
Beef chuck roast is the best choice because its marbling breaks down into tender, juicy bites during long, slow cooking. Stew meat works in a pinch, but avoid lean cuts like round steak, which turn tough and dry.
Q: Can I make this stroganoff stew dairy-free?
Yes, substitute the sour cream with a full-fat coconut cream or a dairy-free sour cream alternative and use dairy-free Worcestershire sauce. Stir it in off the heat just as you would regular sour cream to keep the sauce smooth.
