• Rigatoni Pasta (1 pound): Rigatoni’s large tubular shape is perfect for holding onto sauces and cheese, making every bite flavorful.
• Olive Oil (1 tablespoon): Used for sautéing the onions and creating a rich base for the sauce.
• Sweet Yellow Onion (1 cup, chopped): Adds sweetness and depth of flavor to the dish.

• Garlic (4 cloves, minced): A must for any Italian dish, garlic brings a fragrant richness to the sauce.
• Marinara Sauce (48 ounces or 6 cups homemade): The star of the sauce, it coats the pasta beautifully. You can use store-bought or homemade marinara.
• Italian Seasoning (1 teaspoon): A blend of herbs like oregano, basil, and thyme that brings the essence of Italy to the dish.
• Ground Black Pepper (¼ teaspoon): Adds a subtle warmth without overpowering the other flavors.
• Parmesan Cheese (½ cup, divided): Provides a salty, nutty flavor that enhances the pasta.
• Shredded Mozzarella Cheese (6 ounces or about 1 ½ cups): Melted mozzarella gives the dish that irresistible cheesy top layer.
