Place the cottage cheese and mozzarella cheese in a medium bowl and stir to combine.
Add a thin layer of pasta sauce to the bottom of a slow cooker. Add a thin layer of the cooked ground beef and a layer of the noodles, breaking the noodles to make them fit. Top the noodle layer with a layer of the cheese mixture. Repeat until all of the ingredients are used, ending with a layer of sauce.
Cover and cook on low for 6 to 8 hours. Serve hot.
