I never use ricotta in my recipe since I don't like ricotta. Here's my recipe:
Preheat oven to 350.
Ingredients:
Lasagna noodles
1 lb. of ground beef
1/2 cup chopped onions
1/2 cup green peppers (optional)
1 Jar of Ragu or good quality spaghetti sauce
1 or 2 8oz. blocks of REAL mozzarella cheese--You need about 2 cups shredded
Sprinkle of Parmesan cheese, Italian Seasoning or oregano
Boil the lasagna noodles according to package directions. Sometimes I use the Barilla no-bake noodles using my 8X8 square glass pyrex dish.
Shred a block of REAL Mozzarella cheese. The cheese you buy in the bag has a wax coating that doesn't always melt. I've had better results with the real cheese.
Brown one pound of ground beef, drain. Stir in 1/2 cup of chopped onions and 1/2 cup chopped green peppers (if you like peppers). Cook with onions for about 3 minutes until soft. Add one jar of good quality spaghetti sauce (I use Ragu Traditional or Meat Flavored). Simmer for about 15 minutes until it boils.
Now, do the layering with about 1/4 cup of sauce spread on the pan, then start putting the noodles, meat mixture, cheese, etc. until you are done. Finish off with the mozzarella cheese on the very top. At this point, I like to add some parmesan and sprinkle with Italian seasoning or oregano.
Very important: Before you place your lasagna in the oven, cover it will aluminum foil. Bake it at 350 for 45 minutes with the foil on--the LAST 10 minutes, remove the foil so that the cheese can melt. If you don't use foil, the lasagna will be too dry and/or burn. Remove it from the oven and let it stand for about 15 minutes before cutting.
Enjoy!
