Prep the Chicken: Slice the chicken breasts horizontally to create cutlets or pound them to an even 1/2-inch thickness. Pat dry with paper towels and season with salt and pepper.
Set Up Dredging Station: Prepare three shallow bowls. Place flour in the first. Beat the eggs in the second. In the third, mix the breadcrumbs, grated Parmesan, Italian seasoning, and garlic powder.
Coat the Chicken: Dip each piece of chicken into the flour (shaking off excess), then the egg wash, and finally press firmly into the breadcrumb mixture to ensure a thick, even coating.
Pan Fry: Heat olive oil and 1 tablespoon of butter in a large skillet over medium-high heat. Add the chicken (in batches if necessary) and cook for 4-5 minutes per side until golden brown and crispy. Remove chicken and set aside on a warm plate.
Make the Sauce: In the same skillet, reduce heat to medium. Add the remaining 1 tablespoon of butter and minced garlic. Sauté for 1 minute until fragrant.
Simmer: Pour in the chicken broth to deglaze the pan, scraping up any browned bits. Let it reduce slightly (about 2 minutes).
Finish the Sauce: Stir in the heavy cream and bring to a gentle simmer. Cook for 2-3 minutes until the sauce thickens slightly. Stir in chopped parsley and season with salt and pepper to taste.
Serve: Return the chicken to the pan to warm through briefly, or plate the chicken and spoon the creamy garlic sauce generously over the top.
