Prepare the chicken by slicing, halving, and pounding to even thickness. Season both sides with Kinder’s seasoning, paprika, salt, and pepper, then lightly coat with flour.
Melt butter in a large skillet over medium heat. Cook the chicken in batches, without overcrowding, until golden brown and cooked through. Remove and set aside.
Add diced onion to the pan and cook briefly until softened. Add garlic and cook until fragrant.
Pour in chicken broth to deglaze the pan, scraping up all the browned bits. Season lightly if needed.
Reduce heat to low and stir in heavy cream and freshly shredded Parmesan cheese until smooth and creamy.
Add cooked pasta directly to the sauce and toss to coat.
Return the chicken to the pan, garnish with parsley, and finish with additional Parmesan before serving.
