Ingredients

Scale
  • 2 pounds beef chuck roast, cut into 1-inch cubes
  • 1 tablespoon olive oil
  • 1 large yellow onion, diced
  • 3 cloves garlic, minced
  • 1 pound cremini or white button mushrooms, sliced
  • 2 cups beef broth (low-sodium preferred)
  • 2 tablespoons Worcestershire sauce
  • 1 tablespoon Dijon mustard
  • 1 teaspoon dried thyme
  • 1 teaspoon paprika
  • Salt and freshly ground black pepper
  • 1 cup sour cream, at room temperature
  • 2 tablespoons all-purpose flour
  • 1/4 cup chopped fresh parsley, for garnish
  • 12 ounces wide egg noodles, for serving

Instructions

  1. Pat beef cubes dry and season with salt and pepper. Heat oil in a skillet over medium-high heat. Sear beef in batches until browned on all sides. Transfer to slow cooker.
  2. In the same skillet, add onion and cook for 3-4 minutes until softened. Add garlic and mushrooms; cook 6-8 minutes until mushrooms release liquid and brown.
  3. Pour beef broth into skillet to deglaze, scraping up browned bits. Stir in Worcestershire, Dijon, thyme, and paprika. Simmer 1 minute, then pour mixture over beef in slow cooker.
  4. Cover and cook on LOW for 7-8 hours or HIGH for 4-5 hours, until beef is fork-tender. About 30 minutes before serving, cook egg noodles as directed.
  5. Whisk sour cream and flour in a bowl until smooth. Ladle 1 cup hot liquid from slow cooker into sour cream mixture, whisking constantly. Pour mixture back into slow cooker and stir. Cook on HIGH for 15-20 minutes to thicken.
  6. Serve stroganoff over cooked egg noodles. Garnish with fresh parsley.

Notes

Do not skip searing the beef for maximum flavor. Always temper the sour cream with hot broth to prevent curdling. Store leftovers without noodles; sauce thickens when chilled.
