Prepare the Chicken: Season the chicken breasts with salt, pepper, and 1 teaspoon of paprika on both sides.
Sear the Chicken: In a large skillet, heat the olive oil over medium-high heat. Once hot, add the seasoned chicken breasts. Cook for about 5-7 minutes on each side until they are golden brown and cooked through. Remove the chicken from the skillet and set aside.
Sauté the Vegetables: In the same skillet, add the chopped onion and cook until translucent, about 3 minutes. Add the minced garlic and sauté for another minute until fragrant.
Add Zucchini: Stir in the sliced zucchini and the remaining teaspoon of paprika. Cook for about 5 minutes until the zucchini is tender.
Make the Sauce: Lower the heat and pour in the heavy cream, mixing well. Add the dried thyme and adjust seasoning with salt and pepper to taste. Let the sauce simmer gently for about 3-4 minutes, allowing it to thicken slightly.
Combine and Finish: Return the chicken to the skillet, making sure it's well coated with the creamy sauce. Allow everything to cook together for another 2-3 minutes to heat through.
Serve: Remove from heat, drizzle with fresh parsley, and serve hot.
