How Do You Make Baked Spaghetti? 

Here’s a brief overview of what you can expect when you make homemade baked spaghetti: 

Boil and drain the spaghetti. 

Cook the beef and onion together, then drain off the excess oil. 

Add the sauce and salt. Whisk the eggs, Parmesan, and butter in a separate bowl. 

Toss the spaghetti in the Parmesan mixture. 

Layer the ingredients in a prepared baking dish according to the detailed recipe. 

Cover and bake for 40 minutes. Sprinkle with mozzarella, then keep baking until the cheese is melted. 

How to Store Baked Spaghetti

Cover the (cooled) leftover baked spaghetti tightly or place it in an airtight container. Store it in the refrigerator for up to five days. If you’d like to keep it longer, you can freeze baked spaghetti for up to three months. 

Directions

Step 1

Gather all ingredients. Preheat the oven to 350 degrees F (175 degrees C). Lightly grease a 9×13-inch baking dish.

Step 2

Bring a large pot of lightly salted water to a boil. Cook spaghetti in boiling water, stirring occasionally, until tender but firm to the bite, about 12 minutes. Drain.

Step 3

Meanwhile, heat a large skillet over medium heat. Cook and stir beef and onion in the hot skillet until meat is browned and onion is soft and translucent, about 5 to 7 minutes.

Step 4

Drain excess oil from the pan; stir in spaghetti sauce and seasoned salt.

Step 5

Whisk eggs, Parmesan, and butter in a large bowl. Add spaghetti and toss to coat.

Step 6

Place 1/2 of the spaghetti mixture in the prepared baking dish. Top with 1/2 of the cottage cheese, 2 cups mozzarella, and 1/2 of the meat sauce. Repeat layers. Cover with aluminum foil.

Step 7

Bake in the preheated oven for 40 minutes. Remove the foil and sprinkle with remaining 1 cup mozzarella.

Step 8

Continue to bake until cheese is melted and lightly browned, 20 to 25 minutes.

Step 9

Serve and enjoy!
