Ingredients

Gathering the components for this masterpiece is half the fun. I promise, no weird, hard-to-find items here.

This is about quality, simple ingredients that work together to create something greater than the sum of their parts. The star, obviously, is the meatball mixture. Don’t skip the fresh herbs!

For the Meatballs: 1 lb ground beef (80/20 blend for flavor), 1/2 lb ground pork, 1/2 cup breadcrumbs, 1/2 cup grated Parmesan cheese, 1/4 cup fresh parsley, chopped, 1 large egg, 3 cloves garlic, minced, 1 tsp dried oregano, salt and black pepper to taste.
For the Casserole: 24 oz of your favorite marinara sauce, 8 oz shredded mozzarella cheese, 4 oz provolone cheese, sliced, 1/2 cup ricotta cheese, 1 tbsp olive oil, and fresh basil for garnish (trust me on this one).

Step-by-Step Instructions

Preheat your oven to 375°F (190°C).This is non-negotiable for that perfect, bubbly finish on your Italian Meatball Casserole.
Make the meatball mixture. In a large bowl, combine the beef, pork, breadcrumbs, Parmesan, parsley, egg, garlic, and oregano. Use your hands!It’s the best tool for evenly mixing without overworking the meat. Season generously with salt and pepper.
Form the meatballs. Roll the mixture into 1-to-1.5-inch balls.You should get about 20-24. Pro tip: lightly oil your hands to prevent sticking. This isn’t the time for perfectly spherical art; rustic is charming.
Brown the meatballs.Heat olive oil in a large skillet over medium-high heat. Brown the meatballs in batches, about 2 minutes per side. They don’t need to be cooked through, just seared for flavor.
This step is the difference between good and great.
Assemble the casserole. Spread a thin layer of marinara sauce in a 9×13 inch baking dish. Arrange the browned meatballs evenly over the sauce.Dollop the ricotta cheese around the meatballs, then pour the remaining sauce over everything.
Add the cheese blanket. Top with the shredded mozzarella and layer the provolone slices over that. Do not be shy with the cheese.This is a judgment-free zone.
Bake to perfection. Bake for 25-30 minutes, until the cheese is melted, golden, and the sauce is bubbling around the edges. Let it rest for 5-10 minutes before serving.This prevents a lava-hot sauce burn and allows everything to set.

Common Mistakes to Avoid

Overmixing the meat. This makes the meatballs tough. Mix until just combined, then stop. Your future self will appreciate the tender texture.
Skipping the browning step. I know it’s tempting, but searing adds a deep, caramelized flavor you can’t get from baking alone.Don’t be lazy.
Using low-fat cheese. Just don’t. The fat is flavor and it’s what makes the cheese melt properly. This is not the place for diet food.
Cutting into it immediately. Letting the casserole rest allows the layers to set, so you get a perfect scoop instead of a cheesy puddle.
