# Components:
→ Chicken
01 - 1.3 lbs boneless, skinless chicken breasts or thighs, cut into bite-sized strips
02 - 1/2 teaspoon salt
03 - 1/4 teaspoon black pepper
04 - 2 tablespoons all-purpose flour
→ Vegetables
05 - 9 ounces cremini or white mushrooms, sliced
06 - 1 medium onion, finely chopped
07 - 2 cloves garlic, minced
→ Sauce
08 - 2 tablespoons unsalted butter
09 - 2 tablespoons olive oil
10 - 1 cup chicken stock
11 - 1 tablespoon Dijon mustard
12 - 1 teaspoon paprika
13 - 1/2 cup full-fat sour cream
14 - 2 tablespoons fresh parsley, chopped
# Directions:
01 - Season chicken with salt and black pepper, then toss with all-purpose flour until evenly coated.
02 - Heat 1 tablespoon olive oil and 1 tablespoon butter in a large skillet over medium-high heat. Sauté chicken in batches until golden on all sides but not fully cooked, about 3 to 4 minutes. Remove chicken and set aside.
03 - Add remaining olive oil and butter to the skillet. Sauté onions and mushrooms until soft and golden, about 5 minutes. Stir in minced garlic and cook for an additional 1 minute.
04 - Sprinkle paprika over vegetables, then pour in chicken stock. Stir well, scraping up browned bits from the pan. Incorporate Dijon mustard thoroughly.
05 - Return chicken and any accumulated juices to the skillet. Reduce heat to medium-low and simmer gently for 7 to 8 minutes until chicken is cooked through and sauce thickens slightly.
06 - Remove pan from heat. Stir in sour cream and chopped parsley until smooth and creamy. Adjust seasoning with salt and pepper as needed.
07 - Serve immediately over egg noodles, rice, or mashed potatoes, garnished with extra parsley.
