How to Store Leftover Baked Spaghetti

Once the baked spaghetti is cooled, you will want to store it in the refrigerator. Make sure it is stored in an airtight container. You can move the leftover into a container or you can use a lid if your casserole dish has a lid. You can also wrap the casserole dish well with plastic wrap or aluminum foil.

How Long Does Spaghetti with Italian Sausage Last

When the spaghetti with Italian Sausage meat sauce is stored properly in the refrigerator, it will last for up to 3 days. The great thing about leftover spaghetti with Italian sausage is that after it has sat overnight, the flavors taste even better. The down side of leftover spaghetti is that it can tend to taste dry. This is because the noodles absorb the sauce. If you find that the pasta tastes a little dry, you can add more sauce to it.

Is Baked Spaghetti Like Lasagna

While lasagna and baked spaghetti are both baked pasta recipes, the flavors are slightly different. When you are making lasagna, you are creating a layered pasta recipe. It also has ricotta or cottage cheese in the filling. This baked spaghetti has cream cheese in the filling. This gives the two baked pasta recipes a slightly different taste.

Can I Use Jarred Spaghetti Sauce

If you prefer to not make this Italian Sausage Spaghetti sauce from scratch, you can use a jarred version instead. I would look for a spaghetti sauce that is chunky since it gives you the same texture as the diced tomatoes in this recipe. This sauce is thicker than the typical jarred sauce. You can either play with the ratios to get the consistency you like or you can boil the sauce in a pot. By boiling the sauce, you will thicken it.

How to Reheat Spaghetti and Italian Sausage

When I reheat this spaghetti and Italian Sausage recipe I love to make sure there are leftovers. As I said, it always tastes even better the next day. To reheat it, I like to reheat it in the oven if I am reheating a lot. If it is just a small amount, about the size of a single portion, it is easier to reheat it in the
microwave. You can also reheat portions of this bake in a saucepan.
