Baked Ziti

This one is actually a MaryAnn original. I served it for my husband's birthday and made two large pans. I expected to have tons of leftovers, but it was practically all gone by the next day.

INGREDIENTS:
1 lb package of ziti pasta
1 medium yellow onion, chopped
1 package sliced mushrooms
2-3 cloves garlic, pressed
1 jar spicy arrabiata tomato sauce
1 can diced tomatoes
1 cup light cream
2 cups mozzarella cheese
1 cup Parmesan cheese

DIRECTIONS:
Cook pasta according to package directions. Meanwhile saute onions, mushrooms, and garlic over medium heat in a small amount of olive oil until tender. Stir in tomato sauce and diced tomatoes. Add cream a little at a time until sauce reaches the desired pinkness. In a large bowl, toss sauce with pasta to coat. Next, layer about half the pasta in the bottom of a large baking dish. Cover the layer with mozzarella cheese then spoon on remaining pasta. Top with Parmesan cheese. Cover and bake for 20 minutes at 350 degrees, then uncover and bake for about 5 more minutes or until cheese begins to melt. The recipe will make 8 large servings.
