In a large skillet, heat olive oil over medium heat. Add garlic and sun-dried tomatoes; sauté for 1–2 minutes until fragrant.
Stir in the heavy cream, chicken broth, and Italian seasoning. Simmer for 3–4 minutes to thicken slightly.
Meanwhile, cook the ravioli according to package directions. Drain and set aside.
Add spinach to the sauce and cook until wilted, about 2 minutes.
Stir in Parmesan cheese, then add the cooked ravioli and toss gently to coat in the sauce.
Season with salt and pepper to taste. Serve warm, garnished with extra Parmesan if desired.
