Cook pasta until it's al dente (do not overcook the pasta)

When baking pasta undercooking the pasta for a minute is so much better than overcooking it for a second.

While the pasta is cooking, brown the ground beef in a pan until it's thoroughly cooked.

In a large bowl place pasta, and marinara sauce.

Add to it the ground beef, salt, and pepper to taste along with oregano, and mix well.

In a 13x9 pan create 2 layers of the pasta mixture topping each with a cup of grated Mozzarella Cheese.

Cover the baked ziti with non-stick foil, or foil sprayed with oil so it doesn't stick to the cheese.

Remove the foil during the last 5 minutes of baking.

Bake at 350 degrees for 30-45 minutes.

(If the pasta, sauce, and meat are hot going into the dish it will only take 15-20 minutes to bake)

If the pasta is made a bit ahead of time and has cooled off if the sauce is cold, or room temperature it will take longer to cook 30-45 minutes or until the cheese is melted and when you stick a knife into the center of the dish, the food is hot.
