Ingredients
- 8 ounces uncooked spaghetti

- 1 1/2 cups shredded mozzarella cheese, divided
These five ingredients create a hearty spaghetti pie with a savory meat sauce and a cheesy finish.
Instructions
Step 1: Prepare the Oven and Pasta
Preheat the oven to 350°F (175°C).
Lightly grease a 9-inch deep-dish pie plate or an 8-inch square baking dish.
Bring a large pot of salted water to a boil. Cook the spaghetti according to the package directions until just al dente.
Drain thoroughly and allow the pasta to cool for a few minutes.
Step 2: Cook the Ground Beef
Place the ground beef in a large skillet over medium heat.
Cook, breaking it apart with a spoon, until completely browned and no pink remains.
Drain excess grease carefully.
Stir in the pasta sauce and simmer for approximately 3–5 minutes until heated through.
Step 3: Prepare the Spaghetti Base
Place the slightly cooled spaghetti in a large bowl.
Beat the eggs in a separate small bowl, then pour them over the spaghetti. Add 1/2 cup of the shredded mozzarella and toss until the pasta is evenly coated.
The eggs help bind the spaghetti together as it bakes.
Step 4: Assemble the Pie
Transfer the spaghetti mixture into the prepared pie plate.
Spread it evenly across the bottom and gently press it into place.
Pour the beef and pasta sauce mixture over the spaghetti base, spreading it evenly.
Sprinkle the remaining 1 cup of mozzarella cheese over the top.
Step 5: Bake
Place the dish in the preheated oven.
Bake uncovered for approximately 25–30 minutes, until the cheese is melted and lightly golden and the center is hot.
If the cheese begins browning too quickly, loosely cover the dish with foil.
Step 6: Rest and Serve
Remove the spaghetti pie from the oven and allow it to rest for 10–15 minutes.
This resting time helps the egg-bound spaghetti base firm up, making it easier to cut into neat slices.
Slice into wedges and serve warm.
Helpful Tips for the Best Spaghetti Pie
Cook pasta al dente: Slightly firm spaghetti holds its shape better during baking.
Drain the pasta well: Excess water can make the pie soggy.
Let the pasta cool slightly: This prevents the eggs from scrambling when mixed with the spaghetti.
Use lean ground beef: Less grease helps keep the pie from becoming oily.
Allow time to rest: Cutting immediately after baking can cause the slices to fall apart.
Easy Variations
These optional additions can make the spaghetti pie even more flavorful:
- Italian flavor: Add dried Italian seasoning or oregano.
- Extra cheesy: Replace some of the mozzarella with shredded Parmesan.
- Vegetable version: Add sautéed mushrooms, bell peppers, or spinach to the meat sauce.
- Spicy spaghetti pie: Add red pepper flakes to the sauce.
- Meatless option: Replace the ground beef with sautéed mushrooms or plant-based crumbles.
These are optional additions and substitutions, not part of the original five-ingredient count.
What to Serve with Spaghetti Pie
This hearty dish pairs beautifully with:
- Garlic bread
- A crisp green salad
- Steamed broccoli
- Roasted green beans
- Caesar salad
- Sautéed zucchini
A simple green salad and warm garlic bread make this a complete and satisfying family dinner.
Storage Instructions
Refrigerator: Allow leftovers to cool, then store in an airtight container for up to 3–4 days.
Freezer: Wrap individual slices or the entire cooled pie securely and freeze for up to 2 months.
Reheating: Reheat individual slices in the microwave until steaming hot. For larger portions, cover with foil and warm in a 325°F oven until heated through.
Frequently Asked Questions
Can I make spaghetti pie ahead of time?
Yes. Assemble the pie, cover it, and refrigerate before baking. For best results, bake within 24 hours. Add a few extra minutes to the baking time if it goes into the oven cold, and make sure the center is thoroughly heated.
Can I use a different type of cheese?
Absolutely. Cheddar, Monterey Jack, or an Italian cheese blend can replace mozzarella.
Why is my spaghetti pie falling apart?
The most common reasons are insufficient resting time, too much moisture, or pasta that was not properly coated with the egg mixture. Drain the spaghetti thoroughly and let the pie rest before slicing.
Can I use ground turkey instead of beef?
Yes. Ground turkey works well as a substitute. Cook it completely before adding the pasta sauce.
Can I use leftover cooked spaghetti?
Yes. Use approximately 4 cups of cooked spaghetti. Make sure it is not overly soft before assembling the pie.
How do I know when the pie is ready?
The cheese should be melted, the edges should be bubbling, and the center should be hot. A thermometer inserted into the center should read 165°F when reheating a previously chilled casserole.
