Aunt Peggy's Lasagna

This is pretty much the only lasagna recipe in my family, and it's awesome. I don't know where my aunt got it, but I wanted to share it with everyone.

1 lb. ground beef
9 lasagna noodles
3 tbsp olive oil
1 19oz can stewed tomatoes
2 8oz cans tomato sauce
1 6oz can tomato paste
3 cloves garlic (minced)
1 bay leaf (optional)
1 tsp oregano
1/2 tsp basil
1 small tub cottage cheese
1/2 cup parmesan cheese
1 beaten egg
1 package sliced mozzarella
salt and pepper to taste

Cook ground beef in a large skillet, and drain. Add stewed tomatoes, tomato sauce, tomato paste, garlic, bay leaf, oregano, basil, salt and pepper. Set aside.
Cook lasagna noodles according to package and drain.
Combine the egg and the parmesan cheese in a bowl.
In a pan, layer the following: Sauce, 3 noodles, part of the cottage cheese, part of the parmesan cheese. Cover with 1/3 of the mozzarella. Repeat this two more times. Cover with the remaining sauce (if there is any) and mozzarella cheese.
Cover with tin foil and bake in a 350F oven for 30 minutes. Remove tin foil and bake an additional 15 minutes. Let sit for 10 minutes prior to cutting, so it firms up.
