Fill a large pot with salted water and bring it to a boil. Add spaghetti and cook until al dente, around 8-10 minutes. Drain and set aside.

In a skillet, melt butter over medium heat. Add seasoned chicken breasts and sauté for 5-7 minutes until golden brown and cooked through.

Stir in minced garlic and cook for 1 minute until fragrant.

Add drained spaghetti back into the skillet. Toss everything together and adjust with reserved pasta water if needed.

Serve on plates garnished with grated Parmesan cheese.
