12 lasagna noodles, uncooked
2 tablespoons olive oil
1 (16 ounce) package Italian Ground Sausage
2 cloves garlic, chopped
1 (24 ounce) jar marinara sauce
4 cups ricotta cheese
1 large egg
1/2 cup grated Parmesan cheese
2 cups fresh spinach, lightly packed and chopped
2 cups shredded mozzarella cheese
1 teaspoon dried oregano
1.Bring a large pot of salted water to a boil. Cook pasta until al dente. Drain, lightly oil and set aside.
2.In a medium sauce pan, saute the sausage, crumbling with a wooden spoon, until no longer pink. Add onion and garlic and continue sauteing for another 4 minutes until the sausage is cooked through.
3.Add marinara sauce to the sausage mixture and set aside. In a medium bowl, blend ricotta cheese, egg, 1/4 cup of the parmesan cheese and the chopped spinach; set aside.
4.Coat a 9x13 baking dish with olive oil and spread 1 cup of the sauce mixture on the bottom.
5.Top with 3 lasagna noodles. Spread 1/4 of the ricotta cheese mixture on the noodles and layer on 1 cup of the sauce mixture. Sprinkle 1/2 cup mozzarella cheese over this. Repeat this process three more times starting with the noodles and finish with the remaining 1/4 cup of parmesan cheese. Sprinkle with oregano.
