Pound chicken breasts to an even thickness and season both sides with salt and pepper.
- Set up three shallow bowls: one with flour, one with beaten eggs, and one with a mixture of panko bread crumbs and parmesan cheese.
- Dredge each chicken breast in flour, then dip into the egg, and coat thoroughly in the breadcrumb-parmesan mixture.
- In a large skillet, heat oil over medium heat. Fry chicken until golden and cooked through, about 4–5 minutes per side. Remove and set aside.
- In the same skillet, melt butter and sauté garlic until fragrant, about 1 minute.
- Add chicken broth and bring to a simmer. Stir in heavy cream and parmesan, whisking until smooth.
- Simmer until the sauce thickens slightly, seasoning with salt and pepper to taste.
- Return chicken to the skillet to coat in sauce, or serve with sauce spooned over the top.
- Garnish with chopped parsley if desired.
