Season the chicken with salt, pepper, paprika, garlic powder, and coat lightly in flour.
Heat butter in a Dutch oven over medium heat. Once it starts to brown, add the chicken. Sauté for 3-4 minutes per side, until golden. Remove and set aside.
Sauté the onions and spinach in the same pot for 2-3 minutes.
Add broth and heavy cream, stirring to combine. Bring to a gentle simmer.
Return the chicken to the pot, cover, and cook on low heat for 15-20 minutes, until fully cooked.
Serve over rice pilaf or pasta. Enjoy!
