Behind the Recipe
This recipe came from a simple desire: bring together my love for Tex-Mex flavors and creamy baked pasta into one dish that warms the soul.

What emerged was Monterey Chicken Spaghetti — a comfort food classic with a fresh, flavorful kick.

Named for the use of Monterey Jack cheese — a semi-soft, buttery cheese native to California — this dish marries cheesy goodness with bold seasonings and creamy textures.
