Butterfly the chicken breasts and season with paprika, onion powder, garlic powder, Italian seasoning, salt, and pepper. Heat a frying pan over medium-high heat with a spray of oil. Cook the chicken for a few minutes on each side until golden and cooked through. Remove the chicken from the pan and slice it into strips.
In the same pan, spray a little more oil and add the crushed garlic, oregano, and chili flakes. Cook for about a minute until fragrant. Stir in the chicken stock, cream, and Parmesan cheese.
Add the gnocchi directly into the sauce, stirring to coat. Bring the sauce to a gentle simmer and let it cook for a few minutes until the gnocchi is soft and cooked through.
Add the sun-dried tomatoes, spinach, and sliced chicken to the pan. Stir everything together until the spinach wilts and the chicken is warmed through.
Divide the creamy chicken gnocchi into bowls and serve hot. Pair it with a side of steamed broccoli or your favorite green veggies.
