Season both sides of the chicken breasts with salt, pepper, and paprika.
Heat olive oil in a large skillet over medium-high heat. Sear chicken on both sides until golden brown and cooked through, about 5–7 minutes per side. Remove and set aside.
In the same skillet, add minced garlic and sauté for 1 minute until fragrant.
Pour in chicken broth, scraping up browned bits from the bottom. Stir in heavy cream, Parmesan cheese, and Italian seasoning.
Bring to a simmer and let cook for 3–5 minutes until slightly thickened.
Stir in chopped spinach and sun-dried tomatoes. Let cook until spinach wilts.
Return chicken to the skillet and spoon sauce over the top. Simmer for an additional 2–3 minutes.
Serve warm over pasta, rice, or with crusty bread.
