Essential Kitchen Equipment

Before getting started, make sure you have these tools on hand:

• Large mixing bowl for the meatball mixture
• Medium saucepan for the sauce
• Large skillet for browning the meatballs
• 9×13 inch baking dish
• Parchment paper or aluminum foil
• Instant-read thermometer (recommended but optional)
• Cutting board and sharp knife

Step-by-Step Instructions

Preparing the Meatballs:

1. In a large bowl, combine ground beef, ground pork, breadcrumbs, Parmesan, parsley, minced garlic, diced onion, eggs, Italian seasoning, salt, pepper, and milk.
2. Mix gently with your hands until just combined. Avoid overmixing as this can make the meatballs tough.
3. Let the mixture rest for 10 minutes to allow the breadcrumbs to absorb the moisture.
4. Shape the mixture into meatballs approximately 1 1/2 inches in diameter (you should get about 24-28 meatballs).
5. Heat 2 tablespoons of olive oil in a large skillet over medium heat.
6. Working in batches, brown the meatballs on all sides, about 2-3 minutes per side. They don’t need to be fully cooked through at this stage.
7. Transfer the browned meatballs to a plate lined with paper towels.

Making the Sauce:

1. In the same skillet used for the meatballs, add 2 tablespoons of olive oil.
2. Add the diced onion and cook until translucent, about 3-4 minutes.
3. Add the minced garlic and cook for another 30 seconds until fragrant.
4. Pour in the crushed tomatoes, tomato sauce, and tomato paste. Stir to combine.
5. Add dried oregano, dried basil, red pepper flakes (if using), and sugar.
6. Season with salt and pepper to taste.
7. Bring to a simmer, then reduce heat to low and cook for 15-20 minutes, stirring occasionally.
8. Stir in fresh basil if using.

Assembling and Baking the Casserole:

1. Preheat your oven to 375°F (190°C).
2. Spread about 1 cup of sauce on the bottom of a 9×13 inch baking dish.
3. Arrange the browned meatballs in the baking dish.
4. Pour the remaining sauce over the meatballs, ensuring they’re all covered.
5. Sprinkle the mozzarella, provolone, and Parmesan cheeses evenly over the top.
6. Cover the baking dish with aluminum foil.
7. Bake for 25 minutes covered.
8. Remove the foil and bake for an additional 15-20 minutes, until the cheese is bubbly and golden brown, and the meatballs reach an internal temperature of 165°F (74°C).
9. Let rest for 10 minutes before serving.
10. Garnish with fresh basil or parsley.

Pro Tips for Perfect Meatballs Parmesan Casserole

After making this recipe countless times, I’ve discovered some tricks to take it from good to extraordinary:

• Use a meat mixture: The combination of beef and pork creates more flavorful, tender meatballs than using just one type of meat.
• Don’t skip the browning: While it’s tempting to place raw meatballs directly in the sauce, browning them first creates a richer flavor through caramelization.
• Cheese strategy: Reserve about 1/4 of the cheese to add in the final 10 minutes of baking for the perfect melty-yet-golden top.
• Rest the meat mixture: Allowing the meat mixture to rest before forming meatballs gives the breadcrumbs time to absorb moisture, resulting in juicier meatballs.
• Test for doneness: Use an instant-read thermometer to ensure meatballs reach 165°F (74°C) for food safety.
• Make ahead option: You can prepare the meatballs and sauce up to 2 days ahead, refrigerate separately, then assemble and bake when ready to serve.

Variations to Try

One of the reasons I love this recipe is how adaptable it is. Here are some of my favorite variations:

• Turkey or chicken meatballs: For a lighter version, substitute ground turkey or chicken for the beef and pork.
• Hidden vegetables: Add finely grated zucchini or carrots to the meatball mixture for extra nutrition.
• Spicy kick: Double the red pepper flakes or add a diced jalapeño to the sauce.
• Extra cheesy: Layer some ricotta cheese between the meatballs and top cheese for a lasagna-like experience.
• Herbed up: Add fresh herbs like rosemary, thyme, or oregano to the meatball mixture for an aromatic twist.
• Gluten-free: Use gluten-free breadcrumbs or crushed pork rinds instead of regular breadcrumbs.

Frequently Asked Questions

Can I make this recipe with frozen meatballs? Yes! You can use about 2 pounds of frozen fully-cooked meatballs as a time-saving alternative. Thaw them first or add about 10-15 minutes to the covered baking time if using them frozen.

How do I prevent my meatballs from being tough? Avoid overmixing the meat mixture and don’t pack the meatballs too tightly when forming them. The addition of milk and breadcrumbs helps keep them tender, and being careful not to overcook them is also important.

Can I make this in a slow cooker? Absolutely! Brown the meatballs first, then combine with sauce in a slow cooker. Cook on low for 4-5 hours. Transfer to a baking dish, top with cheese, and broil for 3-5 minutes until the cheese is melted and bubbly.

What’s the best cheese to use? I find the combination of mozzarella, provolone, and Parmesan creates the perfect flavor and melt. However, you can use all mozzarella in a pinch, or experiment with fontina or asiago for different flavor profiles.

Can I add vegetables to this casserole? Yes! Consider adding sautéed bell peppers, spinach, or mushrooms to the sauce. You can also layer roasted vegetables like zucchini or eggplant in the casserole.

How can I make the sauce less acidic? The tablespoon of sugar in the recipe helps balance acidity. You can also add 1/4 teaspoon of baking soda to the sauce, which will neutralize some of the acid without affecting flavor significantly.

Is this recipe suitable for meal prep? Definitely! You can prepare the meatballs and sauce up to 3 days ahead and store them separately in the refrigerator. Assemble and bake when ready to eat. Alternatively, assemble the entire casserole, refrigerate for up to 24 hours, and bake when needed.

What can I substitute for breadcrumbs? You can use panko, crushed crackers, quick oats, or crushed cornflakes. For grain-free options, almond flour or crushed pork rinds work well.
