HOW TO MAKE BAKED SPAGHETTI CASSEROLE
Making Baked Spaghetti Casserole is very similar to making a lasagna — pasta, sauce, and cheese are layered together to create one glorious casserole that’s easy to serve and loved by all.
- Cook the pasta to al dente.
- Add ground beef, onion, and seasoning to pan and cook until beef is browned and cooked through.
- Transfer to mixing bowl, along with crushed tomatoes and cottage cheese.
- In another mixing bowl, combine Parmesan, butter, and eggs. Then, stir in spaghetti.
- Add half of the spaghetti to the casserole dish, followed by half of the meat sauce, and repeat the layers.
- Top with cheese and bake at 350° for 30 minutes.
WHY COOK THE PASTA TO AL DENTE?
Because the pasta will continue to cook in the oven, you want to be sure it’s not overcooked before it goes into the oven. Cooking the pasta to point of al dente will ensure it’s not mushy and overcooked come dinnertime. Al dente pasta still has a little bit of chew to it, but it should not be hard to chew by any means.
ABOUT THE MEAT SAUCE
The homemade marinara meat sauce is eons better than anything you would find from a jar, and in the case of Baked Spaghetti Casserole, it’s actually even easier. There’s no stovetop simmering or wasted time. Because the casserole will bake in the oven, the ground beef, crushed tomatoes, and seasoning have plenty of time to build flavor throughout the duration of the bake.
After the ground beef is browned and the onion is softened, the two will go into a mixing bowl, along with crushed tomatoes and cottage cheese.
However, if you’d rather use storebought marinara in your Baked Spaghetti, this is completely fine. Just omit the seasoning ingredients called for in this recipe, and rather season the ground beef to taste. Then, omit the crushed tomatoes as well, and sub in a 15-ounce jar of storebought marinara sauce
WHY USE COTTAGE CHEESE?
Cottage cheese is a miracle ingredient for Baked Spaghetti Casserole. If you don’t care for it on its own, don’t worry — it takes on the flavors of spaghetti, not the other way around. Cottage cheese in Baked Spaghetti Casserole helps to keep the casserole moist, and the cheese curds that pervade throughout turn into delicious little cheesy morsels.
However, if you’d like you can substitute ricotta cheese for cottage cheese, but note, the casserole will be thicker and slightly drier.
NOODLES AND EGGS | MAKES MORE SENSE THAN YOU THINK
Every part of this recipe is loaded with flavor and the noodles are no exception! After they come out of the boiling water, they go into a mixture of Parmesan cheese, butter, and eggs. The eggs in this recipe serve multiple purposes, one of which is helping the Parmesan to stay put, while the butter adds flavor and helps the mixture to easily coat the noodles.
Normally, when noodles are baked in a casserole they absorb a fair amount of the water content in the sauce. This can result in a dry casserole. Coating the noodles with egg and cheese will help prevent them from sucking up too much moisture from the sauce. The egg will also help to bind the ingredients together, making it easier to cut the Baked Spaghetti Casserole into individual portions.
MORE CHEESE, PLEASE.
Once your meat mixture has been prepared, as well as your noodles, it’s time to layer the two in the casserole dish and top with one last layer of cheese. For this layer, you can use either fresh mozzarella (my personal favorite) or low-fat shredded mozzarella cheese.
If using fresh mozzarella, be sure to pat out the excess moisture with paper towels before topping off your casserole.
Once you’ve got a substantial layer of mozzarella going, you’ll end the whole shebang with an extra sprinkle of Parmesan cheese and bake until beautiful and bubbly.
MAKE-AHEAD BAKED SPAGHETTI CASSEROLE
Starting from the time you make your meat sauce, your Baked Spaghetti Casserole will stay good in the refrigerator for up to 4 days. This means you can assemble it all at once, bake it, and eat on it for 4 days.
The meat and onion mixture can be prepared up to 3 days in advance and refrigerated until ready to use. However, reserve cooking the noodles until you are ready to assemble the casserole.
You can also assemble the entire casserole as indicated in the recipe (up to the point of baking) as far as 3 days in advance. For this preparation, be sure to seal and cover tightly with plastic wrap or aluminum foil, and keep refrigerated until the day you intend to serve it. Note, you’ll want to take the casserole out of the refrigerator and allow it to sit at room temperature for about 45 minutes before baking to remove the chill. Then, bake as directed.
HOW TO FREEZE IT
Once your Baked Spaghetti Casserole has cooled, you can transfer it to a large, freezer-safe zip top bag, taking care to press out any excess air. Store it in the freezer for 2-3 months. For quicker thawing, lay the sealed zip-top a flat surface and freeze it this way.
You could also freeze the contents of the casserole in a freezer-safe, airtight storage container, just be sure there is not a ton of room for air to circulate at the top as this will increase the chances of freezer burn.
