Cook your beef, pork, onion, pepper, and half the garlic in a large skillet over medium-high heat until the meat is cooked through. Mix in the marinara sauce. Set the sauce to the side.
Cook your pasta according to the directions on the box.
16 ounces spaghetti
Melt your butter in a large pot over medium-high heat. Mix in the remaining garlic, heavy cream, parmesan, Italian seasoning, salt, and pepper. Cook until the sauce has started to thicken. Add in the spaghetti and toss until the noodles are coated. Pour the spaghetti into a 9 x 13 casserole pan.
½ cup butter, 2 cups heavy cream, 1 cup grated Parmesan cheese, 1 teaspoon Italian seasoning, 1 teaspoon salt, 1 teaspoon pepper
Pour the meat sauce over the spaghetti and top with the mozzarella cheese.
8 ounces mozzarella cheese
Bake for 20 minutes or until the cheese is bubbly.
Notes
Storage:
To Store: Store leftovers covered in an airtight container for up to five days in the refrigerator.
To Reheat: To reheat, simply microwave until heated through or place in a 350 degree oven until warmed through.
Tips:
You can substitute the jar of store-bought sauce for a homemade sauce. If it already has meat in it, you will not need to add the extra meat.
I prefer to use lean ground beef for this recipe, which is 80-85% lean. If there is any grease, drain it or soak it up with a paper towel before mixing it into the marinara sauce.
Feel free to bake this spaghetti meal in any oven safe dish you have. A casserole dish, baking pan, cast iron skillet, or a disposable aluminum pan will all work well.
