# What You'll Need:
→ 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 oz 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
# How to Make It:
01 - Season chicken evenly with salt and pepper, then toss with flour to coat all pieces.
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 3-4 minutes. Remove and set aside.
03 - Add remaining olive oil and butter to the skillet. Cook onions and mushrooms until softened and golden, approximately 5 minutes. Stir in garlic and cook for an additional minute.
04 - Sprinkle paprika over vegetables, then pour in chicken stock while stirring, scraping any browned bits from the pan. Incorporate Dijon mustard thoroughly.
05 - Return chicken and its juices to the skillet. Reduce heat to medium-low and simmer gently for 7-8 minutes, until chicken is fully cooked and sauce slightly thickens.
06 - Remove skillet from heat and stir in sour cream and chopped parsley until the sauce is smooth and creamy. Adjust seasoning as needed.
07 - Serve immediately over egg noodles, rice, or mashed potatoes, garnished with additional parsley.
