| Large eggs | 2 |
| Grated Parmesan | ½ cup |
| Fresh parsley, chopped | 2 tablespoons |
| Garlic, minced | 3 cloves |

| Salt | 1 teaspoon |
| Ground black pepper | ½ teaspoon |
| Italian seasoning or Herbs de Provence | 1 teaspoon |
For the Sauce and Topping

Step-by-Step Instructions
1. Preheat the Oven
Preheat your oven to 190°C / 375°F.
Lightly grease a large oven-safe baking dish with a little olive oil or cooking spray.
Set the dish aside while you prepare the meatballs.
2. Prepare the Meatball Mixture
Add the ground beef to a large mixing bowl.
Add the breadcrumbs, eggs, grated Parmesan, chopped parsley, minced garlic, finely chopped onion, salt, black pepper, and Italian seasoning.
Gently mix everything together with your hands until the ingredients are evenly incorporated.
Do not overwork the mixture. Mixing too much can make the meatballs dense instead of tender.
3. Shape the Meatballs
Shape the mixture into evenly sized meatballs, approximately the size of a golf ball.
Try to keep the meatballs similar in size so they cook at approximately the same rate.
Arrange them in the prepared baking dish, leaving a little space between each one.
4. Bake the Meatballs
Place the baking dish in the preheated oven.
Bake for approximately 15–20 minutes, or until the meatballs begin to brown and are partially cooked.
Remove the dish from the oven.
If there is a large amount of excess fat in the bottom of the dish, carefully drain some of it before continuing.
5. Add the Tomato Cream Sauce
Pour the marinara sauce evenly over and around the meatballs.
Next, drizzle the heavy cream over the sauce and meatballs.
Gently spread the sauce around the dish without disturbing the meatballs too much.
The combination of marinara and cream creates a rich, smooth tomato cream sauce that surrounds the meatballs as they finish cooking.
6. Add the Cheese
Sprinkle the shredded mozzarella generously over the entire casserole.
Finish with the additional grated Parmesan.
Try to cover most of the surface so the cheese melts into an even, golden topping.
7. Bake Until Golden and Bubbly
Return the casserole to the oven.
Bake for another 15–20 minutes, or until the meatballs are fully cooked and the cheese is melted, bubbling, and lightly golden.
For food safety, check the thickest meatball with an instant-read thermometer. Ground beef should reach at least 71°C / 160°F in the center.
If you want a more deeply golden cheese topping, you can briefly use the broiler at the end, watching carefully to prevent burning.
8. Garnish and Serve
Remove the casserole from the oven and let it rest for a few minutes.
Sprinkle freshly chopped parsley over the melted cheese.
Serve hot while the cheese is still gooey and the tomato cream sauce is warm.
Best Tips for Tender Meatballs
Use ground beef with some natural fat for the most tender and flavorful meatballs. Very lean beef can produce a drier result.
Mix the meatball ingredients gently and stop as soon as everything is combined. Overmixing develops the proteins and can make the meatballs firm.
Make the meatballs approximately the same size so they cook evenly.
Finely chop the onion so it softens properly during baking and blends into the meat mixture.
Let the casserole rest for a few minutes after baking. This gives the sauce a chance to settle and makes serving easier.
Best Ingredient Options
For the ground beef, an 80/20 or 85/15 blend works particularly well because the moderate fat content helps keep the meatballs juicy.
Regular breadcrumbs work well, while soft bread crumbs can create an especially tender texture.
For the cheese, mozzarella is ideal for its excellent melting properties. Parmesan adds a salty, nutty flavor and helps create a delicious golden crust.
You can use homemade or store-bought marinara sauce. Choose a sauce with a flavor you already enjoy because it forms the main base of the casserole.
Heavy cream creates the richest sauce, while crème fraîche provides a slightly tangy and creamy finish.
Recipe Variations
For a garlic and herb version, add a little extra fresh parsley, basil, oregano, or thyme to the meatball mixture.
For a spicy casserole, add crushed red pepper flakes to the marinara sauce.
For extra cheesiness, add a combination of mozzarella, provolone, and Parmesan to the topping.
You can also add finely chopped bell peppers or mushrooms to the tomato sauce for additional vegetables and flavor.
For a lower-carbohydrate variation, replace the breadcrumbs with a suitable low-carb breadcrumb alternative.
What to Serve With Cheesy Meatball Casserole
Serve this casserole with warm crusty bread to soak up the creamy tomato sauce.
A simple green salad with lettuce, cucumber, tomatoes, and a light vinaigrette provides a fresh contrast to the rich cheese and sauce.
Roasted vegetables such as zucchini, broccoli, or bell peppers also make excellent side dishes.
For a heartier meal, serve the meatballs over pasta, rice, or creamy mashed potatoes.
Make-Ahead Instructions
You can prepare the meatballs several hours ahead of time and keep them covered in the refrigerator until ready to cook.
You can also shape the raw meatballs and refrigerate them in an airtight container.
For the best results, prepare the tomato cream sauce shortly before assembling the casserole.
If the meatballs and ingredients are very cold when they go into the oven, the cooking time may need to be slightly increased. Always check the internal temperature rather than relying only on the cooking time.
Storage
Allow leftovers to cool before transferring them to an airtight container.
Store the casserole in the refrigerator for up to 3–4 days.
Keep the meatballs and sauce together for easy reheating.
Reheating
For the best results, place the desired portion in an oven-safe dish and cover loosely with foil.
Reheat at 175°C / 350°F until the meatballs and sauce are heated through.
Individual portions can also be reheated in the microwave. Use short intervals and stir or rotate the portion between intervals when possible.
Freezing
The cooked meatballs and sauce can be frozen for convenient future meals.
Allow the casserole to cool completely before transferring it to a freezer-safe container.
For easier portioning, freeze individual servings rather than the entire casserole.
Thaw overnight in the refrigerator before reheating.
The cheese topping may have a slightly different texture after freezing and reheating, but the casserole will still be flavorful and comforting.
Common Mistakes to Avoid
Avoid overmixing the meatball mixture because this can make the meatballs tough.
Do not make the meatballs dramatically different in size, as smaller ones may overcook while larger ones remain undercooked.
Avoid using too much liquid in the casserole. The marinara sauce and cream should generously coat the meatballs without completely submerging them.
Do not add the cheese too early in the cooking process. Adding it during the second bake allows it to melt beautifully without becoming overly dry.
Always check the internal temperature of the meatballs before serving to ensure the ground beef is fully cooked.
