Ingredients
For the Meatballs:
- 500g ground beef or chicken
- ½ cup breadcrumbs
- 1 egg
- 2 cloves garlic, minced
- ¼ cup grated parmesan
- 2 tablespoons chopped parsley
- Salt and black pepper to taste
For the Casserole:
- 2 cups cooked pasta or cooked rice
- 2 cups marinara or tomato sauce
- 1 small onion, chopped
- 1 teaspoon Italian seasoning
- 1 cup shredded mozzarella cheese
- ½ cup grated cheddar or parmesan
- 2 tablespoons olive oil
Step-by-Step Instructions
1. Prepare the Meatballs
Start by mixing ground meat, breadcrumbs, egg, garlic, parmesan, parsley, salt, and pepper in a bowl. Stir gently until everything combines, keeping the texture light. Shape into medium-sized balls so they cook evenly and stay juicy inside.
2. Cook the Meatballs
Heat a pan with a bit of oil over medium heat. Add the meatballs and cook until browned on all sides. They do not need to be fully cooked yet, since they will finish baking later. Set them aside once they develop a golden outer layer.
3. Cook the Base
If using pasta, boil it in salted water until slightly firm, then drain well. If using rice, make sure it is fully cooked and fluffy. This base will absorb the sauce during baking and hold the dish together.
4. Prepare the Sauce Mixture
In a pan, heat olive oil and sauté the chopped onion until soft. Add the tomato sauce and Italian seasoning, then let it simmer for a few minutes so the flavors blend nicely.
5. Combine Everything
Place the cooked pasta or rice into a large bowl, then pour in the sauce and add the meatballs. Mix gently so everything gets coated evenly without breaking the meatballs.
6. Assemble the Casserole
Transfer the mixture into a baking dish and spread it out evenly. Sprinkle mozzarella and cheddar or parmesan over the top, making sure the surface gets a good layer of cheese.
7. Bake Until Golden
Place the dish in a preheated oven at 180°C and bake for about 25 minutes. The cheese should melt fully and turn slightly golden, while the sauce bubbles around the edges.
8. Let It Rest and Serve
Remove the casserole from the oven and let it sit for a few minutes. This helps everything settle and makes serving easier. Scoop out portions while still warm and enjoy.
Serving Suggestions
A dish like this already feels filling, though a few sides can round it out nicely. Serve it with garlic bread to scoop up extra sauce or add a fresh green salad for balance.
At times, I like placing a bowl of roasted vegetables next to it for a bit of variety. A simple drink like lemonade or juice pairs well and keeps the meal relaxed and easy.
Tips & Variations
Small tweaks can change the flavor and texture while keeping the recipe simple and enjoyable.
- Mix lightly and avoid packing them too tightly.
- Include mushrooms, spinach, or bell peppers for extra flavor.
- Use rice instead of pasta for a different texture.
- Add chili flakes for a bit of heat.
- Broil for a few minutes at the end for a golden crust.
- Stir in a little cream or cheese sauce before baking.
