Prepare the ChickenPreheat your oven to 375°F (190°C). Start by pounding the chicken breasts to an even thickness to ensure consistent cooking. Season each piece with salt, pepper, garlic powder, and onion powder. Next, dredge the chicken in flour, dip it in beaten eggs, and coat it with a mixture of panko breadcrumbs and Parmesan cheese. Heat olive oil in a skillet over medium heat and sear the chicken for 2-3 minutes on each side until golden brown. Transfer to a baking sheet.
Make the Parmesan CrustIn a bowl, mix mayonnaise, sour cream, Parmesan cheese, mozzarella cheese, and Italian seasoning. Spread this mixture evenly over the seared chicken breasts.
BakeBake the chicken in the preheated oven for 20-25 minutes, or until the internal temperature reaches 165°F (74°C). For an extra touch, broil the chicken for the last 2-3 minutes to create a golden, bubbly crust.
Prepare the Garlic Cream SauceMelt butter in a saucepan over medium heat and sauté minced garlic until fragrant. Stir in heavy cream and bring to a gentle simmer. Add Parmesan cheese and whisk until the sauce becomes smooth and creamy. Season with salt, pepper, and a pinch of nutmeg, if desired.
ServePlate the chicken and generously drizzle it with the garlic cream sauce. Garnish with fresh parsley or additional Parmesan cheese for a restaurant-worthy finish.
