Tender chunks of beef in a rich, creamy mushroom sauce spooned over buttery egg noodles. This is the slow cooker dinner that feels indulgent and comforting in equal measure — and it practically makes itself.

Ten minutes of prep, the slow cooker does eight hours of work, and dinner is waiting for you.

Why You’ll Love This Recipe

• Fork-tender beef — Low and slow for 6 to 8 hours transforms budget-friendly stewing beef into something genuinely rich and silky.
• Creamy, savory sauce — Cream of mushroom soup, beef broth, and Worcestershire sauce build a deeply flavored base, finished with sour cream for that classic stroganoff creaminess.
• Comforting and satisfying — Spooned over egg noodles, this is proper comfort food that hits every time.
• One of the easiest slow cooker dinners you can make — Load it up in the morning, stir in the sour cream at the end, boil some noodles. Done.
• Great leftovers — The sauce deepens overnight and the reheated stroganoff is just as good the next day.
• Versatile to serve — Egg noodles are classic, but it works equally well over mashed potatoes or rice.

Ingredients

• 1½ lbs stewing beef or chuck roast, cut into 1-inch cubes
• 1 small onion, finely diced
• 1 can (10.5 oz) cream of mushroom soup
• 1 cup beef broth
• 1 tablespoon Worcestershire sauce
• 1 teaspoon garlic powder
• ½ teaspoon salt
• ½ teaspoon black pepper
• 1 teaspoon dried parsley (optional)
• ¾ cup sour cream (added at the end)
• 8 oz egg noodles, cooked separately

Step-by-Step Instructions

Step 1: Add Beef and Onion

Place the cubed beef and finely diced onion into the slow cooker. Spread in a roughly even layer.

Step 2: Add the Sauce Ingredients

Add the cream of mushroom soup, beef broth, Worcestershire sauce, garlic powder, salt, pepper, and dried parsley. Stir gently to combine everything and coat the beef. The mixture will look thick at this stage — it loosens and becomes saucy as the beef releases its juices during cooking.

Step 3: Cook

Cover and cook on Low for 6–8 hours or High for 4–5 hours, until the beef is completely fork-tender and falls apart easily. Low and slow gives the best result — more tender beef and a richer, more developed sauce.

Step 4: Stir in Sour Cream

In the last 15–30 minutes of cooking, stir the sour cream into the stroganoff. Cover and let it warm through fully — don’t add it too early or at too high a temperature or it can curdle. The sour cream turns the sauce creamy, slightly tangy, and silky.

Step 5: Cook the Noodles

While the sour cream is warming through, cook the egg noodles according to the package instructions. Drain and toss with a little butter.

Step 6: Serve

Spoon the beef stroganoff generously over the cooked egg noodles and serve immediately.

Pro Tips

Cut the beef into consistent 1-inch cubes. Even-sized pieces cook at the same rate. Larger pieces can be underdone when the smaller ones are already falling apart. Take the time to cube it evenly.

Add sour cream at the end, not the beginning. Sour cream added too early or cooked at high heat for too long will curdle and separate, giving you a grainy sauce rather than a smooth one. Add it in the last 15–30 minutes on Low, stir well, and let it warm through gently.

Don’t drain the mushroom soup. The whole can — soup and all — goes in. It forms the base of the sauce and thickens it as it cooks. Draining or rinsing it removes the very thing that makes the sauce rich.

Taste and adjust before serving. The Worcestershire sauce and cream of mushroom soup are both fairly salty. After stirring in the sour cream, taste the sauce and adjust salt and pepper before serving.

Keep noodles and stroganoff separate for storage. Egg noodles absorb sauce overnight and become bloated and soft. Storing them separately and combining per serving keeps everything at the right texture throughout the week.

Variations & Customizations

• Add fresh mushrooms — Slice 8 oz of cremini or button mushrooms and add them to the slow cooker with the beef at the start. They cook down beautifully and add a more pronounced mushroom flavor throughout the sauce.
• Add a splash of heavy cream — Stir in 2–3 tablespoons of heavy cream along with the sour cream at the end for an even richer, more velvety sauce.
• Use Greek yogurt instead of sour cream — Full-fat Greek yogurt gives a slightly tangier, lighter finish. Add it the same way — at the end, off high heat.
• Serve over mashed potatoes — Creamy mashed potatoes are an excellent alternative to egg noodles and make the dish feel even more substantial and comforting.
• Add Dijon mustard — Stir ½ to 1 teaspoon of Dijon mustard into the sauce with the sour cream for a subtle sharpness that’s very traditional in classic stroganoff.
• Use pork tenderloin instead of beef — Cut into cubes and cook on Low for 5–6 hours. The sauce works just as well with pork and gives you a lighter, slightly different dish.

Storage & Reheating

Method	Details
Fridge	Store stroganoff and noodles separately in airtight containers for up to 4 days.
Reheating	Warm stroganoff gently on the stovetop over medium-low heat or in the microwave in short bursts. Add a splash of broth or cream to loosen the sauce as needed.
Freezer	Freeze the beef mixture without noodles for up to 2 months. Thaw overnight in the fridge and reheat gently. Cook fresh noodles when serving.

Frequently Asked Questions

Can I use a different cut of beef?

Chuck roast is the best choice — it has enough fat and connective tissue to become tender and flavorful over a long slow cook. Stewing beef works well too. Avoid lean cuts like sirloin or round which can become tough and dry rather than tender.

My sauce is too thin. How do I thicken it?

Mix 1 tablespoon of cornstarch with 2 tablespoons of cold water and stir it into the slow cooker about 30 minutes before the end of the cook. Alternatively, remove the lid for the last 30 minutes to let some liquid evaporate. The sauce also thickens slightly as it cools.

Can I add mushrooms?

Yes, and it makes the stroganoff significantly better. Slice 8 oz of cremini or chestnut mushrooms and add them with the beef at the start. They soften and blend into the sauce over the long cook, giving you a much more mushroom-forward flavor throughout.

Why did my sour cream curdle?

It was added too early or stirred in while the slow cooker was on High heat. Always add sour cream in the last 15–30 minutes on Low, and stir gently. If it does curdle slightly, a vigorous stir usually brings it back together.

Can I make this on the stovetop?

Yes. Brown the beef in a large pot, add the sauce ingredients, and simmer covered for 1 to 1.5 hours until tender. Stir in sour cream off the heat at the end. Much faster, equally delicious.
