A baked spaghetti casserole with plenty of melted cheese is the perfect dish for potlucks, family gatherings, or a week-night dinner.
1 (16 ounce) package spaghetti
1 pound ground beef
1/2 onion, chopped
1/2 green pepper, chopped
1 (32 ounce) jar meatless spaghetti sauce
1/2 teaspoon seasoned salt
4 cups shredded mozzarella cheese
Preheat oven to 350 degrees. Lightly grease a 9×13-inch baking dish.
Bring a large pot of lightly salted water to a boil. Cook spaghetti in boiling water, stirring occasionally until cooked through. Drain.
Heat a large skillet over medium heat; cook and stir beef, green pepper, and onion until meat is browned and onions are soft and translucent, about 7 minutes. Drain.

Place spaghetti mixture into baking dish. Top with mozzarella.
Bake in oven until the cheese is melted and lightly browned.
