Creating Baked Chicken Stroganoff is simple and rewarding. Just follow these steps:

1. Preheat the Oven: Start by preheating your oven to 375°F (190°C).
2. Sauté the Vegetables: In a large skillet, heat olive oil over medium heat. Add the chopped onions and sauté until translucent, about 3-4 minutes. Stir in the garlic and sliced mushrooms. Cook until the mushrooms are tender, about 5-7 minutes.
3. Prepare the Sauce: In a bowl, combine sour cream, chicken broth, Worcestershire sauce, Dijon mustard, paprika, salt, and pepper. Mix well to create a smooth sauce.
4. Cook the Chicken: Season the chicken breasts with salt and pepper. Place them in a baking dish and cover with the sautéed vegetable mixture.
5. Add the Sauce: Pour the prepared sauce evenly over the chicken and vegetables. Make sure everything is well-coated.
6. Bake: Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 30 minutes.
7. Add Cheese: After 30 minutes, remove the foil and sprinkle shredded cheese on top of the chicken. Bake uncovered for an additional 15 minutes, or until the cheese is bubbly and golden.
8. Rest: Once done, remove the dish from the oven and let it sit for about 5 minutes before serving. This helps the sauce thicken slightly.
9. Garnish: If desired, sprinkle fresh parsley on top for a burst of color.
