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