Spaghetti pie is a hearty, comforting casserole that transforms your favorite pasta dish into a sliceable, pie-shaped meal. Believed to have Italian-American roots, this dish is a popular way to use up leftover spaghetti in a fun and creative form. It combines the best of both worlds — the cozy familiarity of baked pasta and the structure of a savory pie.
What makes spaghetti pie so special is the contrast of textures: the crispy, golden crust formed by baked noodles, the rich, savory meat sauce, and the creamy, cheesy center. It’s a hit with both kids and adults, making it a go-to for family dinners or casual gatherings.
