Ingredients You’ll Need

This easy crockpot beef stroganoff uses familiar ingredients. Here is what each one does and how to swap it.

For the Slow Cooker

• 2 lb beef stew meat or chuck roast: cut into 1 1/2-inch cubes. Chuck has the marbling that turns buttery-soft; trim off large pieces of fat.
• 1 tsp salt and 1/2 tsp black pepper: to season the beef. The soup is salty, so you can always add more at the end.
• 1 large yellow onion, sliced: thin half-moons melt into the sauce. Sweet onions work too.
• 8 oz sliced mushrooms: white button or cremini. Leave them out if your family prefers.
• 3 garlic cloves, minced: fresh garlic gives the best flavor.
• 1 can (10.5 oz) condensed French onion soup: the shortcut that builds the rich onion base. Do not dilute it.
• 1 cup beef broth: low-sodium broth keeps the salt in check.
• 1 tbsp Worcestershire sauce: adds savory depth.
• 1 tsp dried thyme: a classic French onion herb. Use 1 tablespoon fresh thyme leaves if you have them.

To Finish

• 1 cup sour cream, room temperature: full-fat sour cream is least likely to curdle. Plain Greek yogurt works but is tangier.
• 2 tbsp cornstarch plus 2 tbsp cold water (optional): thickens the sauce if you like it extra creamy. All-purpose flour works in a pinch.
• 12 oz wide egg noodles: the traditional choice. Mashed potatoes or rice are great too.
• 2 tbsp chopped fresh parsley: for color and freshness.

How to Make Crockpot Beef Stroganoff

Crockpot beef stroganoff works best in a 6-quart slow cooker. Make sure the beef is fully thawed before it goes in.

Step 1: Season and Sear the Beef (Optional)

1. Pat the beef cubes dry and season them with salt and pepper.
2. For deeper flavor, brown the beef in 1 tablespoon oil in a hot skillet for 2 to 3 minutes per side, working in batches. On busy mornings, skip this step and add the beef raw.

Step 2: Load the Slow Cooker

1. Scatter the sliced onion, mushrooms and garlic in the bottom of the slow cooker.
2. Place the beef on top.
3. Whisk the French onion soup, beef broth, Worcestershire sauce and thyme in a bowl, then pour it over the beef.

Step 3: Slow Cook

1. Cover and cook on LOW for 7 to 8 hours or on HIGH for 4 to 5 hours, until the beef falls apart easily with a fork.
2. Keep the lid on as much as possible so the heat stays steady.

Step 4: Make It Creamy

1. About 30 minutes before serving, stir the cornstarch slurry into the slow cooker if you want a thicker sauce. Cover and cook on HIGH for 15 to 20 minutes.
2. Temper the sour cream: whisk 1/2 cup of the hot cooking liquid into the sour cream in a bowl until smooth.
3. Gently stir the warmed sour cream mixture back into the slow cooker. Taste and add salt and pepper if needed.

Step 5: Cook the Noodles and Serve

1. Meanwhile, boil the egg noodles in salted water until tender, then drain.
2. Spoon the crockpot beef stroganoff over the noodles and sprinkle with fresh parsley.

Always thaw the beef first. Illinois Extension warns not to cook frozen meat in a slow cooker, because it stays too long in the temperature danger zone before it heats through.

Expert Tips for the Best Crockpot Beef Stroganoff

• Choose chuck: lean cuts dry out during long cooking, while chuck stays juicy.
• Put vegetables on the bottom: they cook slower than meat and need to be closest to the heat.
• Never add sour cream at the start: hours of heat make it separate and turn lumpy.
• Temper the sour cream: warming it with hot liquid first keeps the sauce smooth.
• Fill the crock halfway to two-thirds: this helps everything cook evenly.
• Cook the noodles separately: added to the crock, they turn mushy and soak up the sauce.

Slow Cooker vs Stovetop Beef Stroganoff

Classic stovetop stroganoff uses quick-cooking strips of tender steak, seared fast and finished in a pan sauce in about 30 minutes. It is fast, but it needs a pricier cut of beef and attention at the stove.

This slow cooker beef stroganoff uses affordable stew meat and lets time do the work. The long, gentle cook breaks down the connective tissue for incredibly tender bites, and the French onion soup builds flavor you would normally get from caramelizing onions for half an hour.

Variations

• Cream cheese version: stir in 4 oz softened cream cheese with the sour cream for an extra-thick sauce.
• Ground beef: brown 2 lb ground beef, drain and cook on LOW for 4 hours. If you love ground beef in a creamy sauce, try our ground beef gravy too.
• Mushroom lover’s: double the mushrooms and add a splash of red wine with the broth.
• Dijon twist: whisk 1 tablespoon Dijon mustard into the sour cream for a tangy finish.
• French onion topping: sprinkle each bowl with shredded Swiss cheese and crispy fried onions.
• No mushrooms: replace them with an extra sliced onion.

What to Serve With It

Serve this French onion beef stroganoff over egg noodles, buttery mashed potatoes or rice. This beef stroganoff with French onion soup is rich, so steamed green beans, roasted carrots or a crisp green salad are perfect for balance.

Make Ahead and Freezing

Prep ahead: slice the onion and mushrooms and cube the beef the night before. Store them in separate covered containers in the fridge, then load the slow cooker in the morning. If you love set-it-and-forget-it dinners, our dump meal casserole is just as easy.

Freezing: crockpot beef stroganoff freezes well. Freeze the cooked beef and sauce before adding the sour cream for up to 3 months. Thaw overnight in the fridge, reheat on the stove until hot, then stir in tempered sour cream and serve with freshly cooked noodles.

Storage and Reheating

Refrigerate leftovers within 2 hours in shallow containers, as West Virginia University Extension advises in its slow cooker safety guide. Store the crockpot beef stroganoff and noodles separately for up to 4 days.

Reheat gently on the stovetop over medium-low heat with a splash of beef broth, stirring often. Avoid boiling, which can make the sour cream separate. Do not reheat leftovers in the slow cooker.

Frequently Asked Questions

Do I have to brown the beef for crockpot beef stroganoff?

No. Browning adds deeper flavor and color, but the dish is still delicious when you add raw beef straight to the slow cooker.

Why did my sour cream curdle?

It was added too early, was too cold or the sauce was boiling. Temper room-temperature sour cream and stir it in at the end.

Can I use French onion soup mix instead of canned soup?

Yes. Use 1 envelope of dry onion soup mix plus an extra cup of beef broth, and skip the added salt.

Can I cook crockpot beef stroganoff on high?

Yes. Cook on HIGH for 4 to 5 hours. Low and slow gives the most tender beef, so choose LOW when you have time.

Can I add the noodles to the slow cooker?

You can stir in uncooked noodles with an extra cup of broth for the last 20 to 30 minutes on HIGH, but they are softer. Cooking them separately keeps the best texture.
