Ingredients List

For the Meatballs

2 lbs ground beef
½ cup grated parmesan cheese
¾ cup shredded mozzarella cheese
1 egg
¼ cup grated onion
3 garlic cloves, minced
3 tablespoons chopped fresh parsley
½ teaspoon onion powder
½ teaspoon garlic powder
½ teaspoon Italian seasoning
Salt and pepper, to taste

For the Casserole

2 cups marinara sauce (sugar-free)
1 cup shredded mozzarella cheese (for topping)

Instructions

Step 1: Make the Meatballs

Prepare the Meatball Mixture:
- In a large bowl, combine the ground beef, parmesan cheese, mozzarella cheese, egg, grated onion, minced garlic, chopped parsley, onion powder, garlic powder, Italian seasoning, salt, and pepper.
- Mix everything together until fully incorporated.
Form the Meatballs:
- Roll the mixture into meatballs, about 1 ½ inches in diameter. You should get approximately 20–24 meatballs.
Brown the Meatballs:
- Heat a little oil in a large skillet over medium-high heat.
- Brown the meatballs for 2-3 minutes on each side until they develop a golden crust. (They don’t need to be fully cooked through at this stage, as they’ll finish cooking in the casserole.)
- Remove from the skillet and set aside.

Step 2: Prepare the Casserole

Preheat the Oven:
- Preheat your oven to 375°F (190°C).
Assemble the Casserole:
- In a 9×13-inch baking dish, spread 2 cups of marinara sauce evenly on the bottom.
- Place the browned meatballs on top of the sauce, spacing them evenly.
Top with Cheese:
- Sprinkle 1 cup shredded mozzarella cheese over the meatballs.

Step 3: Bake the Casserole

Bake the Casserole:
- Bake in the preheated oven for 25–30 minutes, or until the meatballs are fully cooked (the internal temperature should reach 165°F), and the cheese is melted and bubbly.

Step 4: Serve

Garnish and Serve:
- Once baked, remove from the oven and let it cool for a few minutes.
- Garnish with extra chopped parsley if desired.
- Serve hot and enjoy!

Additional Notes

Make Ahead: You can prepare the meatballs and sauce a day ahead. Assemble the casserole, refrigerate, and then bake when ready to serve.
Flavor Variations: Add fresh basil or oregano to the marinara sauce for extra flavor.
Toppings: For extra flavor, sprinkle parmesan cheese over the top during the last 5 minutes of baking.
