Heat olive oil in a large skillet over medium-high heat.
Season the chicken breasts with salt and pepper, then cook until golden brown on both sides. Remove and set aside.
In the same skillet, sauté minced garlic until fragrant.
Add heavy cream, chicken broth, and Parmesan cheese, stirring until the sauce thickens.
Stir in Italian seasoning, then return the chicken breasts to the skillet. Simmer until the chicken is cooked through.
Garnish with chopped parsley and serve immediately.
