Ingredients & Substitutions

  • Meatballs: For this slow cooker meatball stroganoff, you can use any meatballs you prefer (including vegetarian options). However, it’s necessary to select meatballs that taste good since they’re the main component of the dish.
  • Kosher Salt: All of my recipes are tested with Morton kosher salt unless noted otherwise. It is the best salt for everyday cooking because of its size and flavor. If using table salt, the amount should be reduced. I highly recommend picking up some kosher next time you are at the store!
  • Noodles: I recommend using egg noodles for this crock pot meatball stroganoff recipe since they soak up the rich sour cream sauce well. However, you can use any noodles you have on hand. Noodles with a tube shape or ridges are best since they hold more sauce than other varieties.

Step by Step Instructions

Cook on high if you need the stroganoff to be ready sooner.

Do not add sour cream while the heat is still on, as it can curdle.

Step 1: Add the meatballs, mushrooms, onion, garlic, mustard, Worcestershire, soy, thyme, paprika, onion powder, salt, pepper, and broth to the slow cooker. Cook on HIGH for 3 hours or LOW for 6 hours.

Step 2: Whisk together the cornstarch and about 1/4 cup of the broth from the slow cooker.

Step 3: Stir the cornstarch mixture into the slow cooker. Cook for an additional 30 minutes on HIGH or 1 hour on LOW. The sauce should thicken up slightly.

Step 4: While the sauce thickens, boil the egg noodles if using. Turn the slow cooker off and stir in the pasta and sour cream.

Recipe Serving Suggestions

Garnish with fresh herbs, a dollop of sour cream, or slices of chives/green onions.

If I don’t cook noodles with this slow cooker meatball stroganoff, I will make a potato or bread side dish to help sop up the sauce from this easy meatball stroganoff. Here are a few ideas:

Expert Tips

  • Use cornstarch. Adding cornstarch (or flour) is key to creating slow cooker meatball stroganoff sauce. Without this ingredient, the sauce will be overly watery.
  • Create a slurry. If you add dry cornstarch directly into frozen meatball slow cooker recipes, like this stroganoff meatballs dish, you’ll end up with a clumpy sauce. You can ensure the cornstarch dissolves correctly by mixing it with water first to create a slurry. Once it’s dissolved in the water, add it to the sauce.
  • Temper the sour cream. Adding sour cream to the stroganoff sauce while the crock pot is on will lead to a curdled sour cream. You can also avoid curdling the sour cream by adding a spoonful of the hot sauce into the sour cream first and combining. This step will help bring the sour cream’s temperature up. Then, you can mix the tempered sour cream into the stroganoff sauce.

Additions & Variations

  • Homemade Meatballs – If you’re using homemade meatballs, it’s best to brown them on the stove first. This extra step helps create a crispy crust, which can help keep the meatballs from falling apart in the slow cooker.
  • Sauté Onions, Mushrooms, and Meatballs – You can create more flavor by browning these ingredients first. This note works for frozen and fresh meatballs.
  • Vegetarian – Turn this easy beef stroganoff with frozen meatballs dish into a vegetarian-friendly option with a few swaps. Use vegetable broth and vegetarian/vegan meatballs instead of beef or pork.

Recipe FAQs

Is beef stroganoff the same as Swedish meatballs?

No, these two dishes are not the same. Swedish meatballs are made from ground meat, while beef stroganoff typically includes strips or cubes of beef. In this slow cooker meatball stroganoff, I’ve combined meatballs with a stroganoff sauce.

What is the difference between stroganoff and Swedish meatball sauce?

Stroganoff and Swedish meatballs both have a creamy sauce and beef broth base. However, there are a few differences between the two. Stroganoff sauce has mushrooms, while Swedish meatball sauce does not. Another key difference is the seasoning for each sauce. Swedish meatballs are typically seasoned with spices like nutmeg and ginger, while Stroganoff sauce includes paprika, onion powder, and thyme.
