Ingredients

  • 1/2 lb. Italian sausage
  • 1 large onion, chopped
  • 1/2 tsp. Italian seasoning
  • 48 oz. can spaghetti sauce
  • 1 c. water
  • 8 oz. ziti pasta
  • 12 oz. shredded Mozzarella
  • 1/2 c. shredded Parmesan
  • 1/2 lb. ground beef
  • 1/2 tsp. garlic
  • 1/2 tsp. salt
  • 3 1/2 oz. sliced pepperoni

Instructions

  1. Brown the ground beef, Italian sausage, chopped onion, and garlic in a skillet until cooked through.
  2. Add Italian seasoning, spaghetti sauce, water, and sliced pepperoni; simmer for 15 minutes.
  3. Meanwhile, boil the ziti pasta until al dente, then drain.
  4. Mix the cooked pasta with the sauce mixture.
  5. Transfer the mixture into a 9 x 13-inch baking pan.
  6. Cover the casserole with shredded mozzarella and Parmesan cheese.

Tips & Substitutions

For a twist, consider adding vegetables like bell peppers or mushrooms to the meat mixture. You can substitute the Italian sausage with turkey sausage or omit it for a vegetarian version. If you don't have ziti, penne or rigatoni work well too. Enhance flavor with fresh basil or oregano instead of dried. For a creamier texture, mix in some ricotta cheese before baking.

Serving Suggestions

Serve this hearty ziti spaghetti casserole with a side salad for a balanced meal, and some garlic bread or a crusty loaf to soak up the sauce. It pairs beautifully with Dip For Bread for an added flavor kick. For a complete Italian-inspired dinner, consider serving it alongside Jean'S Manicotti.

Storage & Reheating

Allow the casserole to cool completely before storing. Cover it tightly with plastic wrap or aluminum foil and refrigerate for up to 3 days. To reheat, place individual portions in the microwave or reheat the entire dish in a 350°F oven until warmed through, about 20-25 minutes.

Frequently Asked Questions

Can I make this casserole ahead of time?

Absolutely! You can assemble the casserole a day in advance and store it in the fridge before baking. Just add a few extra minutes to the baking time if baking straight from the fridge.

Can I freeze leftovers?

Yes, you can freeze the casserole. Wrap it tightly in foil or plastic wrap and store it in the freezer for up to 3 months. To reheat, thaw in the refrigerator overnight and bake as directed.

What can I use instead of Mozzarella cheese?

If you're out of Mozzarella, you can use provolone or a blend of Italian cheeses. For a sharper flavor, consider using cheddar or a mixture of Parmesan and Asiago.
