About the Ingredients

Spaghetti – I use a whole box (1 pound) but it’s a lot. We always have leftovers for lunchboxes the next day. You can cut it back to 3/4 of a pound without altering anything else in the recipe.

Italian Sausage – Removed from the casings and crumbled while cooking.

Onion – Diced and cooked before adding to the spaghetti casserole.

Tomato Sauce – There’s no shame in jarred sauce, especially for a pasta bake casserole like this that is loaded with cheese. The sauce isn’t going to be a star of the meal so jarred is just as good as the homemade stuff this time. I like to use Classico Organic.

Cheese – Ricotta and shredded cheddar are mixed into the spaghetti before baking. Then top off the spaghetti casserole with shredded mozzarella and a sprinkle of parmesan.

Eggs – 3 eggs beaten and mixed into the casserole filling will bind the baked spaghetti together and keep it from falling apart when serving.

Seasonings – Italian seasoning, salt and pepper

Jarred tomato sauce, an onion, Polly-o ricotta cheese, 3 eggs, a box of spaghetti, bowl of shredded cheddar cheese and package of Italian sausage meat.

How to Make Baked Spaghetti with Ricotta

Cook the Sausage, Onion and Pasta

The first step is to cook the sausage and onion together in on the stovetop. Stir the sausage to a crumble while it browns all the way through and diced onion softens and turns translucent.

While the sausage and onion are cooking, it’s the perfect time to boil the pasta water and get the spaghetti cooking. Cook the spaghetti according to directions on the box and then drain it and set aside.

Make the Filling

In a large mixing bowl, beat the eggs so the yolks are broken and the whites and yolks are scrambled. Add the tomato sauce, ricotta, cheddar cheese, salt and pepper to the beaten eggs. Fold in the cooked spaghetti and the sausage and onion and continue to toss until the pasta is evenly coated in the sauce and cheese mixture.

Assemble and Bake

Spray a large baking dish with cooking spray. Pour in the spaghetti mixture. Top off the tray of spaghetti with shredded mozzarella, a little grated parmesan cheese and a sprinkle of Italian seasoning.

Bake the spaghetti with ricotta casserole at 350°F for 20 minutes or until hot and bubbly.

Storage Recommendations

Even though this baked spaghetti recipe is so good we always have leftovers. Intentionally making a bigger portion than we can eat in one sitting guarantees leftovers for lunch during the week.

Slice the baked spaghetti into individual portions and store it in a sealed container in the refrigerator for up to 3 days. The spaghetti will dry out a little so if you have some extra tomato sauce, save that in the refrigerator too but store it separately.

Reheat the individual portions of baked spaghetti either in a covered dish in the oven or in the microwave but before heating pour on a few tablespoons of the reserved tomato sauce.

Freezing Baked Spaghetti with Ricotta

Freezing a tray of baked spaghetti is a great make ahead meal. It also makes a terrific casserole dinner to deliver to a friend, especially since it appeals to so many tastes.

To freeze baked spaghetti simply assemble the casserole all the way through but don’t bake it. Let it cool to room temperature and then cover it foil and plastic wrap and freeze it for up to 2 months.

When you’re ready to defrost your casserole, move it to the refrigerator overnight. Then let it sit at room temperature for about 1 hour before baking it at 350°F covered with foil (be sure to remove the plastic wrap!) for 30 minutes. Remove the foil and bake for another 15 minutes or until hot and bubbly.

Frequently Asked Questions

Is baked spaghetti the same as lasagna?

Baked spaghetti has the same flavors as lasagna but it uses spaghetti pasta instead of sheets of lasagna noodles. It also isn’t layered but rather all of the ingredients are evenly combined throughout.

How do you keep baked spaghetti from drying out?

The ricotta has a high moisture content so by adding the right amount of sauce and ricotta cheese your spaghetti bake should stay moist. Also be careful to not over-bake the casserole. You just want to heat it enough to cook the eggs and melt the cheese. Everything else is already cooked so don’t over do it on the time in the oven.

Should you bake pasta covered or uncovered?

The pasta is already cooked when it goes in the oven so it doesn’t need to cook long; only long enough to combine with the other ingredients. Cooking it uncovered will prevent condensation and moisture building up and get you that night crunchy golden crust on the top of your pasta bake.
