Equipment You’ll Need

• 9-inch deep-dish pie plate
• Large mixing bowl
• Medium mixing bowl
• Rubber spatula or large spoon
• Cheese grater (if using block cheese)

Ingredients

• 4 cups leftover cooked spaghetti (preferably with some sauce already on it)
• 2 large eggs, lightly beaten
• 1/2 cup grated Parmesan cheese, divided
• 15 ounces whole-milk ricotta cheese
• 1/4 cup chopped fresh parsley or 1 tablespoon dried parsley
• 1 teaspoon Italian seasoning
• 1/2 teaspoon garlic powder
• 1/4 teaspoon salt
• 1/4 teaspoon black pepper
• 1 cup your favorite marinara or pasta sauce, plus more for serving
• 2 cups shredded mozzarella cheese

Instructions

1. Preheat your oven to 375°F (190°C). Grease a 9-inch deep-dish pie plate with butter or non-stick cooking spray.
2. In a large mixing bowl, combine the leftover spaghetti, beaten eggs, and 1/4 cup of the Parmesan cheese. Toss thoroughly until every strand of pasta is coated in the egg mixture. This is the binder that will create your ‘crust’.
3. Transfer the spaghetti mixture to the prepared pie plate. Using your hands or a spatula, press the spaghetti firmly and evenly across the bottom and up the sides of the plate to form a crust. Create a slight rim around the edge.
4. In a separate medium bowl, stir together the ricotta cheese, the remaining 1/4 cup of Parmesan cheese, parsley, Italian seasoning, garlic powder, salt, and pepper until well combined.
5. Spoon the ricotta mixture evenly over the spaghetti crust, spreading it out to the edges.
6. Pour the 1 cup of marinara sauce over the ricotta layer, spreading it gently.
7. Sprinkle the shredded mozzarella cheese evenly over the top, covering the sauce completely.
8. Place the pie plate on a baking sheet to catch any potential drips. Bake for 30-35 minutes, or until the cheese is melted, bubbly, and lightly golden on top. The center should be set.
9. Remove the spaghetti pie from the oven and let it rest on a wire rack for at least 10 minutes before slicing. This step is crucial; it allows the pie to set, ensuring clean, beautiful slices.
10. Slice into wedges and serve warm, with extra marinara sauce on the side if desired.

Expert Cooking Tips

• For the best crust, ensure your leftover pasta is cool or at room temperature. If it’s too hot, it can start to cook the eggs prematurely.
• Don’t be shy when pressing the spaghetti into the pie plate. A firm, compact crust is key to the pie holding its shape.
• For an extra crispy top, switch the oven to the broil setting for the last 1-2 minutes of cooking. Watch it carefully to prevent burning.
• If your leftover pasta is dry, toss it with a tablespoon of olive oil before mixing it with the eggs to help loosen it up.

Substitutions and Variations

Feel free to customize this pie to your liking. You can substitute cottage cheese for ricotta for a lighter version. Any long pasta like linguine or fettuccine works well. For a non-vegetarian option, add a layer of cooked ground beef, crumbled Italian sausage, or mini pepperoni between the ricotta and sauce layers. You can also mix in cooked vegetables like spinach (squeeze out all excess water), sautéed mushrooms, or roasted red peppers into the ricotta filling.

Common Mistakes to Avoid

The most common mistake is slicing the pie immediately after it comes out of the oven. It will be too hot and loose, causing the slices to fall apart. Allowing it to rest for 10-15 minutes is essential for it to set. Another pitfall is not using enough egg binder for the amount of pasta, which also leads to a crumbly structure. Make sure all the spaghetti is well-coated. Finally, using a standard (not deep-dish) pie plate can cause overflow; if you only have a standard one, slightly reduce the amount of filling.

Serving Suggestions

This Cheesy Baked Spaghetti Pie is a hearty meal on its own, but it pairs wonderfully with a few simple sides. Serve each slice with a crisp, refreshing green salad dressed in a light vinaigrette to cut through the richness. Classic garlic bread or warm, crusty Italian bread is perfect for scooping up any extra sauce. For a more complete meal, a side of steamed green beans, roasted broccoli, or sautéed zucchini adds a healthy and delicious vegetable component.

Storage and Reheating Tips

Leftover spaghetti pie stores beautifully. Allow it to cool completely, then cover the pie plate tightly with plastic wrap or foil, or transfer individual slices to an airtight container. It will keep in the refrigerator for up to 4 days. To reheat, you can microwave individual slices for 1-2 minutes or place the entire pie (or multiple slices) in an oven preheated to 350°F (175°C) for 15-20 minutes, or until heated through.

Frequently Asked Questions

Can I make this with freshly cooked pasta?

Can I assemble the spaghetti pie ahead of time?

Yes, you can assemble the entire pie, cover it tightly with plastic wrap, and refrigerate it for up to 24 hours before baking. You may need to add 5-10 minutes to the baking time since it will be starting from cold.

Is spaghetti pie freezer-friendly?

Yes, it freezes very well. You can freeze the entire baked and cooled pie by wrapping it tightly in several layers of plastic wrap and then a layer of foil. Or, you can freeze individual slices. It will keep for up to 3 months. Thaw overnight in the refrigerator before reheating in the oven.
