Step 1

Preheat oven to 350 degrees. Spray an extra deep 9X13 inch baking dish (See notes above) with nonstick cooking spray; set aside. Do Not use a standard 13XYou can use a 9X13 inch baking dish that has sides that are 3 inches high.

Step 2

In a large pot over medium-high heat, add the beef and sausage and sprinkle with salt and pepper. Brown mixture, crumbling into large pieces. Transfer to a paper towel-lined plate. Discard all but 2 tablespoons of drippings from pot. If you don't have that amount remaining, add olive oil to make up the difference.

Step 3

Add the onion, garlic, and 3 teaspoons Italian seasoning and saute, over medium-high heat, until soft, about 5-7 minutes. Return beef and sausage to the pot. Add half of the marinara sauce (2 cups or 1 jar), water, and heavy cream to the onion and meat, turn the heat to low and heat through; set aside.

Step 4

Meanwhile, bring another large pot of water, with 1 tablespoon of salt, to a boil. Cook ziti according to the package instructions. Drain well, then return pasta to original pot off the heat, and add the remaining half (2 cups or 1 jar) of marinara sauce to pasta and combine; set aside.

Step 5

In a medium bowl, stir together ricotta, egg, remaining 1 teaspoon Italian seasoning, and nutmeg; set aside.

Step 6

Spoon a thin layer, about 1 cup of meat sauce in the bottom of an extra deep 13 by 9-inch pyrex. Pour half the ziti in the baking dish. Spread all the ricotta mixture over ziti, then sprinkle half the parmesan, half the mozzarella, and half the sauce.

Step 7

Spread the remaining ziti, then the remaining sauce, mozzarella, and Parmesan. Bake in preheated oven, uncovered 25-30 minutes or until cheese is golden and sauce is bubbly.
