Ingredients:
- 1 pound ground beef
- 1 pound Italian sausage
- 1 cup breadcrumbs
- 1/2 cup grated Parmesan cheese
- 1/4 cup chopped fresh parsley
- 2 cloves garlic, minced
- 1 large egg
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 jar (24 ounces) marinara sauce
- 1 loaf of Italian bread or hoagie rolls
- 2 cups shredded mozzarella cheese
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- Olive oil for drizzling
Preparing the Meatballs
First things first, lets get our meatballs ready. This is where the magic begins!
- In a large mixing bowl, combine the ground beef and Italian sausage. I like to use a mix of both for flavor and texture, but you can use just one if you prefer.
- Add the breadcrumbs, grated Parmesan cheese, chopped parsley, minced garlic, egg, salt, and black pepper to the meat mixture. The egg acts as a binder, so dont skip it!
- Using your hands (I find this is the best way), mix everything together until just combined. Be careful not to overmix, as this can make the meatballs tough.
- Once mixed, form the mixture into meatballs, about 1 to 1.5 inches in diameter. You should get around 20-24 meatballs, depending on the size you choose.
Cooking the Meatballs
Now that we have our meatballs ready, its time to cook them. You can bake or pan-fry them, but I prefer baking for ease and less mess.
- Preheat your oven to 400°F (200°C). This will ensure that the meatballs cook evenly and get a nice golden color.
- Line a baking sheet with parchment paper or aluminum foil for easy cleanup. If you have a wire rack, place it on top of the baking sheet to allow the fat to drain off.
- Place the meatballs on the prepared baking sheet, making sure they are spaced out evenly. This helps them cook properly without steaming.
- Bake the meatballs in the preheated oven for about 20-25 minutes, or until they are cooked through and reach an internal temperature of 160°F (70°C). You can also broil them for the last 2-3 minutes for a crispy exterior.
Preparing the Marinara Sauce
While the meatballs are baking, lets prepare the marinara sauce. You can use store-bought or homemade, but I usually go for a good quality jarred sauce for convenience.
- In a medium saucepan, pour the marinara sauce and heat it over medium heat. Stir occasionally to prevent it from sticking to the bottom.
- Add the dried oregano and basil to the sauce. This will enhance the flavor and make it more aromatic.
- Once the meatballs are done baking, carefully add them to the saucepan with the marinara sauce. Gently stir to coat the meatballs in the sauce. Let them simmer for about 5-10 minutes on low heat to meld the flavors.
Preparing the Bread
Now, lets get our bread ready for the casserole. This is where well build our delicious meatball sub casserole!
- If youre using a loaf of Italian bread, slice it in half lengthwise. If youre using hoagie rolls, you can leave them whole or slice them down the middle.
- Place the bread on a baking sheet. Drizzle a little olive oil over the cut sides of the bread for added flavor and to help it crisp up in the oven.
- Toast the bread in the oven for about 5-7 minutes, or until its lightly golden. This step is crucial as it prevents the bread from becoming soggy once we add the sauce and meatballs.
Assembling the Casserole
Conclusion:
In wrapping up this delightful Meatball Sub Casserole Dish, I cant emphasize enough why this recipe is a must-try for anyone looking to impress family and friends or simply enjoy a comforting meal at home.
