Creating the amazing Slow Cooker Beef Stroganoff is simple if you follow these steps:

1. Sear the Beef: In a skillet, heat olive oil over medium-high heat. Sear the beef on all sides until browned, about 3-5 minutes.

2. Add Aromatics: Transfer the seared beef to your slow cooker. Add diced onion, minced garlic, and sliced mushrooms on top.

3. Mix Broth and Seasonings: In a bowl, combine beef broth, Worcestershire sauce, dried thyme, paprika, salt, and pepper. Pour this mixture over the meat and vegetables in the slow cooker.

4. Slow Cook: Cover and cook on low for 6-8 hours or on high for 3-4 hours until the beef is tender.

5. Prepare Sour Cream Mixture: In a small bowl, mix sour cream with flour until smooth to ensure no lumps.

6. Add Sour Cream: About 30 minutes before serving, stir the sour cream mixture into the slow cooker. Cover and cook on high for an additional 30 minutes to thicken the sauce.

7. Check for Seasoning: Before serving, taste and adjust seasonings as needed.

8. Garnish: Once done, sprinkle chopped fresh parsley over the beef stroganoff for a burst of color and flavor.

9. Serve: Serve hot over pasta, rice, or mashed potatoes for a fulfilling meal.
