Step 1

Preheat oven to 350°F. Oil a lasagna (baking) pan and spread 1 cup sauce on the bottom. Mix the remaining sauce with the cooked ground beef. Set aside.

Step 2

Cook the lasagna noodles in boiling water. (Be sure to take them out before they are completely done—about 1 minute before package instructions suggest—so they don’t overcook when you bake the lasagna.) Place one layer of noodles over the sauce layer in the pan.

Step 3

In a bowl combine the eggs, ricotta, and 1 cup mozzarella cheese until well blended. Stir in the parsley and salt and pepper to taste.

Step 4

Spread half of the ricotta mixture over the noodles in the pan. Top the ricotta with a layer of noodles. Ladle 2 cups of the meat sauce over the noodles; top with another layer of noodles.

Step 5

Spread the remaining ricotta mixture over the noodles. Top with the last of the noodles. Ladle the remaining meat sauce over the noodles.

Step 6

Scatter the remaining mozzarella cheese over the sauce; sprinkle it with the Parmesan cheese. Bake for 1 hour and 25 minutes.
