Heat the olive oil in a large skillet over medium heat.
Add the chopped onion and garlic. Cook for 3–4 minutes until softened and fragrant.
Season the chicken breasts with paprika, cumin, salt, and black pepper.
Add the chicken to the skillet and cook for 4–5 minutes on each side until lightly browned.
Pour in the heavy cream and gently stir to combine with the onions and garlic.
Reduce the heat to low and simmer for 12–15 minutes, or until the chicken is fully cooked and the sauce has thickened.
Spoon the creamy sauce over the chicken and garnish with freshly chopped parsley.
Serve your Turkish Chicken with Creamy White Sauce hot with rice, pasta, mashed potatoes, or crusty bread.
