6 boneless, skinless chicken breasts3 tbsp olive oilSalt and black pepper, to taste2 tsp garlic powder1 tsp paprikaFor the Sauce2 cups heavy cream1 cup freshly grated Parmesan cheese2 tsp Dijon mustard2 tsp lemon juice1 tsp dried thyme or Italian seasoningOptional GarnishFresh parsley, chopped
Instructions
Preheat oven to 375°F (190°C) and lightly grease a large baking dish.Pat chicken breasts dry and rub with olive oil.Season both sides with salt, pepper, garlic powder, and paprika.(Optional) Sear chicken in a hot skillet for 2 minutes per side for extra color and flavor.In a bowl, whisk together heavy cream, Parmesan cheese, Dijon mustard, lemon juice, and dried thyme until smooth.Place chicken in the baking dish and pour sauce evenly over the top.Cover with foil and bake for 25–30 minutes, until chicken is cooked through and sauce is bubbling.Remove foil and bake uncovered for 5 more minutes to lightly brown the top.Let rest for 5 minutes before serving. Garnish with fresh parsley if desired.
Notes
Use freshly grated Parmesan for the best flavor and texture.Do not overbake—this keeps the chicken juicy.Swap chicken breasts for thighs if preferred.Add baby spinach, mushrooms, or bacon for extra flavor.
