Season the chicken: Pat chicken breasts dry and season with salt and pepper on both sides.
Sear the chicken: Heat olive oil and 20 g butter in a large skillet over medium heat. Cook chicken for about 5–6 minutes per side until golden brown. Remove and set aside.
Make the sauce: In the same skillet, melt the remaining butter. Add minced garlic and sauté for 30 seconds until fragrant.
Add liquids: Pour in chicken broth and heavy cream, scraping up browned bits from the pan.
Add cheese and herbs: Stir in Parmesan and Italian herbs. Simmer for 3–4 minutes until slightly thickened.
Combine: Return the chicken to the pan and spoon the sauce over it. Simmer 3–4 minutes until heated through.
Serve: Garnish with chopped parsley and serve with pasta, rice, or roasted potatoes.
