Why I Love This Spaghetti Pie Recipe

This easy spaghetti pie made with cottage cheese and leftover spaghetti is easy to love because it turns simple leftovers into a comforting, satisfying meal. It’s a budget-friendly way to reduce food waste while creating something that feels fresh and intentional, not like leftovers at all. The recipe comes together quickly with minimal prep, making it perfect for busy weeknights. Cottage cheese adds a creamy texture and extra protein without the heaviness of ricotta, keeping the dish both filling and lighter. Baked into a pie, the familiar spaghetti flavors become cozy, sliceable comfort food that the whole family enjoys. It’s endlessly customizable with meat, vegetables, or extra cheese. Best of all, it works beautifully as a make-ahead dinner (like my easy make-ahead lasagna), and reheats well for next-day lunches.

Spaghetti Pie Equipment

To make this recipe from leftover spaghetti noodles and sauce you will need some simple, basic kitchen equipment:

A 10-inch pie plate or pan

A large mixing bowl (microwaveable if you are going to heat your noodles before putting the spaghetti pie together)

A small mixing bowl

A wooden spoon for mixing

A spatula for spreading the cottage cheese and sauce

Measuring cups and measuring spoons

Spaghetti Pie Ingredients

4 cups cooked spaghetti noodles (8 ounces of dry noodles if you are making this without leftovers)

3 tablespoons olive oil or butter

2 eggs, well beaten

1/2 cup plus 2 tablespoons grated Parmesan cheese (divided)

1 cup cottage cheese (2% or 4%)

1 cup spaghetti sauce (if you have a bit more leftover spaghetti sauce, you can use a little more)

1/2 cup grated mozzarella cheese

Spaghetti Pie Instructions

Preheat oven to 350 degrees. Lightly grease a 10-inch pie plate and set aside.

In a large microwaveable bowl toss spaghetti with olive oil. Warm the bowl of spaghetti noodles in the microwave for 30 seconds (optional).

In a small bowl, combine eggs and 1/2 cup Parmesan cheese. Stir into spaghetti. Pour spaghetti mixture into prepared pie plate, spreading to form a crust. I like to indent the middle of the crust slightly to hold more cottage cheese and sauce.

Spread cottage cheese evenly over the crust, but not quite to the edge. Top with spaghetti sauce.  Bake, uncovered, for 25 minutes. Top with shredded mozzarella and bake for 5 minutes longer, until cheese melts. Remove the spaghetti pie from the oven and sprinkle with the remaining 2 tablespoons of Parmesan cheese. Cool for 10 minutes before cutting into wedges.

Spaghetti Pie Variations

There are many ways you can change up this easy spaghetti pie recipe. My spaghetti sauce itself turns out differently depending on what kinds of options I have from my garden or pantry shelves. I like to mix in olives, mushrooms, and even sneak in some cooked butternut squash. There are many options. Here are some more ideas you might want to try:

Spaghetti Pie with Ricotta Cheese

Substitute the cottage cheese in this recipe for ricotta cheese. Although the fat content is higher, the creaminess of the  ricotta adds a special touch.

Meatless Spaghetti Pie

No meat in your spaghetti sauce? No problem! This spaghetti pie is delicious using spaghetti sauce without meat as well.

Reduced Fat and Cholesterol Spaghetti Pie

To reduce the fat and cholesterol in this recipe, you could use nonfat cottage cheese or egg substitute in place of the eggs called for in the recipe.
