Prepare the Chicken: Season the chicken breasts with salt, pepper, thyme, and paprika on both sides.
Brown the Chicken: In a large skillet, heat olive oil over medium-high heat. Add the chicken breasts and cook for 5-6 minutes on each side, or until golden brown and cooked through. Remove the chicken from the skillet and set aside.
Sauté Garlic: In the same skillet, reduce the heat to medium and add the minced garlic. Sauté for about 30 seconds, or until fragrant, being careful not to burn it.
Create the Sauce: Pour in the chicken broth, scraping up any browned bits from the bottom of the skillet. Bring to a simmer and cook for 2-3 minutes.
Add Cream and Spinach: Lower the heat and mix in the heavy cream, stirring until combined. Add spinach and let it wilt in the sauce for about 2 minutes.
Combine: Return the chicken to the skillet, spooning the creamy garlic sauce over the top. Let it simmer for an additional 3-4 minutes to heat through and meld the flavors.
Garnish and Serve: Sprinkle chopped parsley over the chicken before serving.
