Creating Creamy Slow Cooker Chicken Stroganoff is straightforward when following these steps:

1. Prepare Chicken: Season the chicken thighs with salt and pepper and place them in the slow cooker.
2. Add Vegetables: Scatter the chopped onion, sliced mushrooms, and minced garlic over the chicken.
3. Mix Wet Ingredients: In a bowl, whisk together the chicken broth, Worcestershire sauce, and paprika. Pour this mixture over the chicken and vegetables.
4. Cook in Slow Cooker: Cover and cook on low for 4-6 hours or on high for 2-3 hours until the chicken is tender.
5. Thicken the Sauce: Once cooked, remove the chicken and whisk together the sour cream and flour in a bowl. Stir this mixture into the slow cooker until well combined.
6. Return Chicken: Shred the chicken with two forks and return it to the slow cooker. Stir to coat the chicken in the sauce.
7. Final Seasoning: Adjust seasoning with additional salt and pepper to taste. Let it cook for an additional 15-30 minutes to heat through.
8. Serve: Spoon the stroganoff over your choice of noodles, rice, or potatoes, and garnish with fresh parsley if desired.

This straightforward approach ensures that even novice cooks can achieve delicious results without hassle.
