Part 1: Ingredients and Equipment

Creating a standout meatball casserole requires more than just combining meat, sauce, and cheese. Each component—from the ground meat to the seasoning, the binding agents, the sauce, and the baking dish—plays a critical role in the texture, flavor, and success of the final dish. Below is a breakdown of the necessary ingredients and equipment to ensure your meatball casserole turns out flavorful, tender, and satisfying.

A. Meatball Ingredients

1. Ground Meat (1 ½ pounds total)

• Ground beef (80/20): Provides a hearty, beefy flavor and good fat content.

• Ground pork (optional): Adds richness and a slightly sweet note.

• Ground veal or turkey (optional): Use to lighten the mixture or for dietary preferences.

Tip: Use a 50/50 mix of ground beef and ground pork for a juicy and flavorful blend.

2. Breadcrumbs (¾ cup)

• Use plain or Italian-seasoned breadcrumbs. Panko can also be used for a slightly lighter texture.

6. Garlic (2–3 cloves, minced)

Part 2: Step-by-Step Instructions

This part outlines the full preparation of your meatball casserole in five main stages: mixing and forming meatballs, browning, making the sauce, assembling the casserole, and baking. Each step includes detailed guidance to avoid common pitfalls.

Step 1: Preparing the Meatball Mixture

1. Soak the Breadcrumbs

   • In a large mixing bowl, combine ¾ cup breadcrumbs with ½ cup milk.

   • Let it sit for 5–10 minutes until it forms a thick paste.

2. Add Remaining Ingredients

   • Add to the breadcrumb-milk mixture:

     • 1½ pounds of ground meat (beef, pork, or a mix)

     • 2 eggs

     • ½ cup grated Parmesan

     • Minced garlic and grated onion

     • 2 tablespoons chopped parsley (optional)

     • 1 to 1½ teaspoons kosher salt

     • ½ teaspoon black pepper

3. Mix Gently

   • Use clean hands to mix until just combined. Overmixing can result in tough meatballs.

   • The texture should be soft but hold together well when formed.

4. Form Meatballs

   • Roll the mixture into balls, about 1½ inches in diameter (or 2 tablespoons each).

   • You should yield about 20–24 meatballs.

Tip: Lightly oil your hands to prevent sticking.

Step 2: Browning the Meatballs (Optional but Recommended)

1. Heat Oil

   • In a large skillet or on a foil-lined baking sheet under the broiler, add a few tablespoons of olive oil.

   • Heat over medium-high until shimmering.

2. Brown in Batches

   • Sear meatballs in batches for 2–3 minutes per side, just until browned.

   • Do not overcrowd the pan.

3. Set Aside

   • Transfer browned meatballs to a plate lined with paper towels.

Why Brown First?

• Browning locks in flavor and adds a delicious crust. You can skip this step and bake meatballs directly if short on time, but the flavor will be less complex.

Step 3: Preparing the Tomato Sauce

1. Sauté Aromatics

   • In a saucepan over medium heat, warm 2 tablespoons olive oil.

   • Add chopped onion and cook until soft and translucent, about 5 minutes.

   • Stir in minced garlic and cook 30 seconds more.

2. Add Tomato Base

   • Stir in 2 tablespoons tomato paste and cook for 1–2 minutes to deepen the flavor.

   • Add the crushed tomatoes, herbs, sugar, salt, and pepper.

3. Simmer the Sauce

   • Bring to a simmer, then reduce heat to low.

   • Simmer uncovered for 15–20 minutes, stirring occasionally.

   • Taste and adjust seasoning as needed.

Tip: You can blend the sauce for a smoother texture, or leave it chunky depending on preference.

Step 4: Assembling the Casserole

1. Preheat the Oven

   • Set to 375°F (190°C).

2. Layer the Sauce

   • Spoon a thin layer of tomato sauce into the bottom of a greased 9×13-inch baking dish.

3. Add the Meatballs

   • Arrange browned (or raw) meatballs over the sauce in a single layer.

4. Top with Remaining Sauce

   • Pour the rest of the sauce evenly over the meatballs.

5. Add Cheese

   • Sprinkle shredded mozzarella generously over the entire dish.

   • Add grated Parmesan or Pecorino for a sharper top layer.

Optional Additions:

• Add cooked pasta before baking for a full one-dish meal.

• Include sautéed spinach or mushrooms for more depth.

Step 5: Baking the Casserole

1. Bake Uncovered

   • Place casserole in the center of the oven.

   • Bake for 25–30 minutes, or until the sauce is bubbling and the cheese is melted and golden.

2. Optional Broil

   • In the final 2–3 minutes, switch to broil to brown the cheese slightly—but watch closely to prevent burning.

3. Rest Before Serving

   • Let the casserole sit for 5–10 minutes after removing from the oven. This allows the sauce to thicken and makes serving easier.

4. Garnish and Serve

   • Sprinkle with freshly chopped basil or parsley for freshness and color.

   • Serve with garlic bread, pasta, or a side salad.
