Ingredients
  

  • 1 16 ounce package thin spaghetti
  • 4 cups prepared spaghetti sauce
  • 1 cup small curd cottage cheese
  • ½ cup fat-free sour cream
  • 1 12 ounce package shredded mozzarella cheese

Instructions
 

  • Preheat oven to 400 degrees F (200 degrees C).
  • Grease a 9x13-inch baking dish.
  • Fill a large pot with lightly salted water and bring to a rolling boil. Stir in spaghetti and return to a boil. Cook until pasta is tender but still slightly firm, about 10 minutes. Drain well.
  • Transfer spaghetti to a large bowl and toss with spaghetti sauce until well combined.
  • Mix cottage cheese and sour cream in a bowl.
  • Spread half the spaghetti with sauce into the prepared baking dish.
  • Spread the cottage cheese mixture evenly over the spaghetti.
  • Place the remaining spaghetti and sauce in an even layer over the cottage cheese mixture; sprinkle with mozzarella cheese.
  • Bake in the preheated oven until bubbly and the cheese is browned, 30 to 40 minutes.

Notes

I like to take spicy Italian sausage and bake it in the oven while I prepare everything else. Then before I put the first layer of spaghetti in the baking dish, I put the sausage on the bottom of the pan and then do my layers, baking as usual.
