Creating Chicken Stroganoff is straightforward if you follow these simple steps:

1. Heat Oil: In a large skillet, heat the olive oil over medium-high heat.
2. Cook Chicken: Add the chicken pieces to the skillet. Season with salt and pepper. Cook for about 5-7 minutes until browned and cooked through. Remove chicken from the skillet and set aside.
3. Sauté Onions and Mushrooms: In the same skillet, add the diced onions and sliced mushrooms. Sauté for about 5 minutes or until softened.
4. Add Garlic: Stir in minced garlic and cook for an additional 1 minute until fragrant.
5. Create the Sauce: Sprinkle flour over the sautéed veggies. Stir constantly for about 1 minute to create a roux.
6. Add Liquid Ingredients: Slowly whisk in chicken broth, Worcestershire sauce, and Dijon mustard. Bring to a simmer and let thicken slightly for about 4-5 minutes.
7. Stir in Sour Cream: Reduce heat to low and add the sour cream to the skillet. Stir until well combined and heated through—do not boil.
8. Return Chicken: Add the cooked chicken back into the skillet. Stir to coat with the sauce and heat until warmed.
9. Prepare Noodles/Rice: While the sauce is warming, cook the egg noodles or rice according to package instructions.
10. Serve: Once everything is ready, spoon the Chicken Stroganoff over the noodles or rice. Garnish with fresh parsley.
