Cook your spaghetti to al dente. Drain and set aside to cool slightly.
Preheat oven to 350°F.
Once your spaghetti is cool enough to handle, stir together the cottage cheese, garlic, eggs, salt, and pepper. Toss the noodles in this mixture and press into a well greased 9x13 pan.
Place meatballs on top of spaghetti and distribute sauce over the casserole.
Cover and bake for 35-40 minutes.
Remove cover and sprinkle with mozzarella cheese. Return to oven uncovered to bake for 10-15 minutes or until cheese is melted and browned to your liking.
Allow to sit for 10 minutes, then cut and serve.
Notes
Feel free to use a tub of ricotta cheese instead of cottage cheese if that is your preference, it is good either way.You can use homemade meatballs in this recipe. Cook them according to your recipe's directions before putting them on the casserole. Frozen meatballs also work great. They help to make this a quick and easy meal.
