Preheat your oven to 375°F (190°C).
Season the chicken breasts with salt and black pepper.
Heat the oil in a large oven-safe skillet over medium-high heat. Add the chicken breasts and cook until browned on both sides, about 3-4 minutes per side. Remove the chicken from the skillet and set aside.
Reduce the heat to medium-low and add the minced garlic to the skillet. Sauté for about 1 minute until fragrant.
Add the sundried tomatoes and spinach to the skillet. Cook for 2-3 minutes until the spinach wilts.
Pour in the heavy cream, grated Parmesan cheese, dried basil, and dried oregano. Stir well to combine.
Return the chicken breasts to the skillet, nestling them into the creamy tomato mixture.
Transfer the skillet to the preheated oven and bake for about 10-15 minutes for thinner chicken breast and 20-25 minutes for thicker chicken breast or until the chicken is cooked through and reaches an internal temperature of 165°F (74°C).
Once cooked, remove the skillet from the oven and let it rest for a few minutes.
Garnish the chicken with chopped fresh parsley.
