Instructions

Season beef cubes with salt and pepper. For best flavor, sear beef in a hot skillet with oil until browned on all sides (optional but recommended).
Place the seared or raw beef, sliced onions, mushrooms, and minced garlic into the slow cooker insert.
In a bowl, whisk together beef broth, Worcestershire sauce, tomato paste, Dijon mustard, smoked paprika, and dried thyme. Pour over the beef and vegetables in the slow cooker. Stir to combine.
Cover and cook on LOW for 7-8 hours or on HIGH for 4-5 hours, until beef is fork-tender.
About 30 minutes before serving, in a small bowl, whisk the sour cream and flour into a smooth paste. Scoop out about ½ cup of the hot liquid from the slow cooker and whisk it into the sour cream mixture to temper it.
Stir the tempered sour cream mixture back into the slow cooker. Replace the lid and cook on HIGH for an additional 20-30 minutes to allow the sauce to thicken.
While the sauce thickens, cook egg noodles according to package directions.
Taste stroganoff and adjust seasoning with salt and pepper if needed. Serve the creamy beef stroganoff over hot egg noodles. Garnish with fresh parsley if desired.

Notes

For a gluten-free version, use a gluten-free flour blend or a cornstarch slurry (3 tbsp cornstarch mixed with 3 tbsp cold water) instead of the all-purpose flour. Always temper the sour cream with hot broth to prevent curdling. Leftovers can be stored in the refrigerator for up to 4 days.
