Preheat the oven to 425F and prepare a casserole dish.
Pound the chicken breasts to thin them out, make sure they’re similar thickness.
Place chicken breasts inside the casserole dish.
In a small bowl, combine all the chicken seasoning ingredients.
Drizzle the chicken with olive oil and rub the chicken breasts with the seasoning mixture. Cover them with sundried tomatoes.
In a bowl, whisk together heavy cream, chicken broth, garlic powder, and sea salt.
Pour the heavy cream mixture over the chicken and sprinkle with Parmesan cheese to cover all the chicken breasts.
Bake in the oven for 25-30 minutes until the chicken is fully cooked. Once finished, remove from the oven.
Stir the spinach into the sauce and cover the baking dish with foil for another 5-10 minutes to let the spinach wilt.
