Season chicken with salt, pepper, and Italian seasoning.
Heat olive oil in a large skillet over medium-high heat. Cook chicken for 4–5 minutes per side until golden brown and cooked through. Remove and set aside.
In the same skillet, sauté garlic for 1 minute until fragrant.
Add sun-dried tomatoes, chicken broth, and heavy cream. Stir to combine.
Stir in parmesan cheese until the sauce is creamy and smooth.
Return chicken to the skillet, spoon sauce over the top, and simmer for 5 minutes.
Garnish with fresh parsley or basil and serve immediately.
