Begin by slicing your thin boneless skinless chicken breasts horizontally to create even cutlets. Pat them dry with a paper towel, then dredge each piece in a mixture of flour, salt, black pepper, garlic powder, and Italian seasoning, ensuring they are well coated for that crispy texture.

In a large skillet, heat 2 tablespoons of olive oil over medium-high heat until shimmering. Carefully add the prepared chicken cutlets and cook for 4-5 minutes on each side, or until they turn a beautiful golden brown and reach an internal temperature of 165°F. Once cooked, transfer them to a plate and cover to keep warm.

In the same skillet, reduce the heat to medium and add 4 tablespoons of butter. Once melted, toss in the chopped yellow onion and minced garlic, sautéing until the onion becomes translucent, about 2-3 minutes. Next, add the diced tomatoes and a sprinkle of flour, whisking to combine and cook for another 2 minutes.

Slowly pour in 1 cup of heavy cream and 1 cup of white wine, stirring continuously to blend the flavors. Bring the mixture to a gentle simmer, allowing it to thicken for about 5-7 minutes. Stir in salt, pepper, and crushed red pepper flakes, adjusting the seasoning according to your taste preferences.

While the sauce simmers, cook 12 ounces of spaghetti according to the package instructions until al dente, typically around 8-10 minutes. Once cooked, drain the pasta, reserving about ½ cup of the pasta water to adjust the sauce’s consistency if needed.

Toss the drained spaghetti into the creamy sauce, and add the cooked chicken back to the skillet. Mix everything thoroughly, adding a splash of reserved pasta water if the sauce is too thick, and heat together for 2-3 minutes until everything is well combined and heated through.

Plate the creamy chicken pasta in generous bowls and garnish with shredded Parmesan cheese and fresh herbs as desired. Enjoy the creamy, comforting flavors and watch as your family indulges in this delightful dish!
