Ingredients

Scale
  • 2 pounds beef chuck roast, cut into 1-inch cubes
  • Kosher salt and freshly ground black pepper
  • 1 large yellow onion, thinly sliced
  • 3 cloves garlic, minced
  • 1 pound cremini mushrooms, sliced
  • 2 tablespoons tomato paste
  • 1 teaspoon paprika
  • 1 teaspoon dried thyme
  • 2 tablespoons all-purpose flour
  • 1 1/2 cups beef broth
  • 1 tablespoon Worcestershire sauce
  • 1 bay leaf
  • 2/3 cup sour cream, at room temperature
  • 2 tablespoons Dijon mustard
  • 1/4 cup chopped fresh parsley, for garnish
  • Cooked egg noodles, for serving

Instructions

  1. Pat beef cubes dry and season generously with salt and pepper. In a large skillet over medium-high heat, sear beef in batches until browned on all sides. Transfer to a 6-quart slow cooker.
  2. In the same skillet, add onion and cook until softened, about 5 minutes. Add garlic and mushrooms; cook until mushrooms release liquid and brown, 8-10 minutes.
  3. Stir in tomato paste, paprika, and thyme; cook for 1 minute. Sprinkle flour over mixture and stir for 1 minute.
  4. Gradually pour in beef broth and Worcestershire sauce, scraping up browned bits. Simmer for 1 minute until slightly thickened, then pour over beef in slow cooker. Add bay leaf.
  5. Cover and cook on LOW for 6-8 hours or on HIGH for 3-4 hours, until beef is fork-tender.
  6. About 15 minutes before serving, cook egg noodles. Turn slow cooker off. In a bowl, whisk sour cream and Dijon until smooth. Whisk in 1/2 cup of hot cooking liquid from the slow cooker to temper.
  7. Stir the creamy mixture back into the slow cooker until fully incorporated. Discard bay leaf. Taste and adjust seasoning.
  8. Serve stroganoff over cooked egg noodles, garnished with fresh parsley.

Notes

For a gluten-free version, use a gluten-free flour blend or a cornstarch slurry. Always temper the sour cream with hot liquid to prevent curdling. Do not add dairy until the end of cooking.
