Spaghetti Pie

6 cups leftover cooked spaghetti (or other pasta)
1 egg
1 teaspoon Italian Herb seasoning
1 1/2 cups shredded cheddar cheese
1/4 cup melted butter
1/2 pound ground beef
1 small onion, chopped
1 jar marinara sauce
1/2 cup grated Parmesan cheese

Preheat oven to 350ºF.

In a large mixing bowl, combine pasta, egg, herb seasoning, cheddar cheese and butter. Mix well.

Spray a 9 x 13 pan with cooking spray, put spaghetti mixture into the pan and spread evenly.

In a saucepan over medium high heat, brown ground beef and onions together until nicely browned. Drain any grease. Spread ground beef and onions over the top of the pasta mixture in the pan.

Pour the bottled marinara sauce over the ground beef mixture, spreading to the edges. Sprinkle the top with the Parmesan cheese.

Bake in a 350ºF oven for 30 minutes, or until bubbling nicely.
