- 1 (16 ounce) package spaghetti
- 1 pound ground beef
- 1 onion, chopped
- 1 (32 ounce) jar meatless spaghetti sauce
- ½ teaspoon seasoned salt
- 2 eggs
- ⅓ cup grated Parmesan cheese
- 5 tablespoons butter, melted
- 2 cups small curd cottage cheese, divided
- 4 cups shredded mozzarella cheese, divided
- Step 1
Preheat oven to 350 degrees F (175 degrees C). Lightly grease a 9×13-inch baking dish.
- Step 2
Bring a large pot of lightly salted water to a boil. Cook spaghetti in boiling water, stirring occasionally until cooked through but firm to the bite, about 12 minutes. Drain.
- Step 3
Heat a large skillet over medium heat; cook and stir beef and onion until meat is browned and onions are soft and translucent about 7 minutes. Drain. Stir in spaghetti sauce and seasoned salt.
- Step 4
Whisk eggs, Parmesan cheese, and butter in a large bowl. Mix in spaghetti to egg mixture and toss to coat. Place half the spaghetti mixture into a baking dish. Top with half the cottage cheese, mozzarella, and meat sauce. Repeat layers. Cover with aluminum foil.
- Step 5
Bake in preheated oven for 40 minutes. Remove foil and continue to bake until the cheese is melted and lightly browned, 20 to 25 minutes longer.
