Preheat your oven to 375°F (190°C).
Season the chicken breasts with salt, pepper, paprika, and dried thyme.
In a large oven-safe skillet, heat olive oil over medium-high heat. Add the seasoned chicken breasts and cook until golden brown on both sides, about 3-4 minutes per side.
Remove the chicken from the skillet and set aside.
In the same skillet, add minced garlic and sauté for about 1 minute until fragrant.
Add chicken broth to deglaze the pan, scraping up any browned bits from the bottom.
Stir in heavy cream, sun-dried tomatoes, and chopped spinach. Simmer for 2-3 minutes until the sauce starts to thicken.
Return the chicken breasts to the skillet, nestling them into the sauce.
Sprinkle grated Parmesan cheese over the chicken and sauce.
Transfer the skillet to the preheated oven and bake for 20-25 minutes, or until the chicken is cooked through and the sauce is bubbly.
Once done, garnish with fresh parsley and serve hot.
