Servings: 4 servings

Ingredients

  • 1 to 1.5 pounds frozen fully cooked meatballs (beef or turkey)
  • 1 medium onion, finely chopped
  • 8 ounces cremini or button mushrooms, sliced (optional but recommended)
  • 1 can (10.5 ounces) condensed cream of mushroom soup
  • 1 cup beef broth (low-sodium preferred)
  • 2 tablespoons Worcestershire sauce
  • 1 teaspoon Dijon mustard (optional, for depth)
  • 1 teaspoon garlic powder (or 2 cloves fresh, minced)
  • 1 teaspoon onion powder (boosts savory flavor)
  • ½ teaspoon paprika (sweet or smoked)
  • ½ teaspoon black pepper (plus more to taste)
  • 8 ounces wide egg noodles (or serve over rice or mashed potatoes)
  • ¾ to 1 cup sour cream (full-fat for the creamiest texture)
  • 2 tablespoons cornstarch mixed with 2 tablespoons cold water (optional thickener)
  • Fresh parsley, chopped, for garnish (optional)
  • Salt, to taste (add at the end)

Instructions

  • Prep the base: In your slow cooker, whisk together the cream of mushroom soup, beef broth, Worcestershire sauce, Dijon, garlic powder, onion powder, paprika, and black pepper until smooth.
  • Add veggies and meatballs: Stir in the chopped onion and sliced mushrooms. Add the frozen meatballs and roll them gently to coat in the sauce.
  • Set and cook: Cover and cook on Low for 5–6 hours or High for 2.5–3.5 hours, until the meatballs are heated through and the onions are tender.
  • Thicken (if needed): If the sauce looks thin, stir in the cornstarch slurry, cover, and cook on High for another 15–20 minutes until slightly thickened.
  • Cook the noodles: About 20 minutes before serving, cook egg noodles according to package directions. Drain well.
  • Add the sour cream: Turn the slow cooker to Warm. Stir in 3/4 cup sour cream until fully combined and creamy. Add more to taste for extra richness.
  • Season and serve: Taste and add salt if needed. Spoon the stroganoff over egg noodles, rice, or mashed potatoes. Garnish with chopped parsley for a fresh finish.
