Baked spaghetti pie is a ground beef pasta bake that holds its shape when sliced — think of it as a cross between a frittata and a pasta casserole. It uses cooked spaghetti, eggs, mozzarella, browned ground beef, and yellow bell pepper, all baked together in one dish. It’s worth making because it produces a full meal with almost no extra pans, and the leftovers reheat better than most pasta dishes.
About the ingredients
- Eggs as binder: This is what makes the pie slice cleanly instead of falling apart. Don’t skip them or reduce the quantity — they’re structural, not just for protein.
- Yellow bell pepper: Any color works. Green will be slightly more bitter; red or orange will be sweeter. Use whatever you have.
- Mozzarella: Low-moisture, part-skim mozzarella melts more evenly and releases less water than fresh mozzarella. Fresh will make the center soggy — skip it here.
- Ground beef: An 80/20 blend works well. Leaner beef is fine but drain thoroughly either way — excess fat will pool at the bottom of the pie.
The short version of why this works
Two things matter most here. First, the cold-oven start: placing the assembled pie in a cold oven that then heats to 400°F lets the egg-and-pasta base set gradually from the outside in, which prevents rubbery edges and a wet center. Second, leaving the pie in the turned-off oven for 15 minutes after baking isn’t optional — that carry-over time is what firms the interior enough to slice without the whole thing collapsing. Pull it too early and you’ll have a scoop, not a slice.
If something goes sideways
- The center is still loose after baking: The eggs needed more time. Put the pie back in the oven at 375°F for 8–10 minutes before doing the resting step again.
- The bottom is wet or greasy: The ground beef wasn’t drained well enough before mixing. Next time, tilt the pan and spoon off the fat, or blot with paper towels before combining with the pasta.
- The pie won’t release from the dish: It wasn’t greased, or it was cut too soon. Run a thin spatula around the edge, let it rest another 5 minutes, then try again.
- The top cheese is browning too fast: Tent loosely with foil for the last 10 minutes of baking — skip the garnish on top entirely, not worth the extra dish.
- The pasta clumped into a solid mass: Day-old spaghetti that dried out needs to be loosened with a tablespoon of water and tossed before mixing with the eggs, or the egg won’t coat evenly.
Leftovers and meal prep
Slices keep in the fridge for up to 4 days in an airtight container. Reheat individual slices in a skillet over medium-low heat with a lid on — about 5 minutes — and the texture stays closer to the original than microwave reheating, which softens the crust. For freezing, wrap individual slices tightly in plastic wrap, then foil, and freeze for up to 2 months. Thaw overnight in the fridge before reheating. You can also assemble the entire unbaked pie the night before, refrigerate it covered, and bake it straight from the fridge the next day — add 5 minutes to the baking time to account for the cold start.

Ingredients
Instructions
- Brown the beef in one large pan, and saute your vegetables in another. Mix eggs, cheese, and cooked spaghetti in a large mixing bowl; combine vegetables and beef when finished. Pour contents into a large casserole dish.
- Do not pre-heat your oven! Instead, place the dish into the cold oven, and turn it to 400 degrees Fahrenheit, letting it bake for 30 minutes. Turn off your oven after the 30 minutes but leave it in for 15 minutes to set better.
- Slice your pie and serve with your choice of sauce, or enjoy alone!

FAQ
Can I use leftover spaghetti that already has sauce on it?
Yes, and it works well. Sauced pasta adds flavor, but if it’s heavily coated, reduce any additional salt in the recipe and expect a slightly softer texture since the sauce adds moisture.
How do I know the ground beef is fully cooked before it goes into the pie?
It should be browned all the way through with no pink remaining — ground beef needs to reach an internal temperature of 160°F (71°C). Since the beef gets mixed into the pie before baking, make sure it’s fully cooked in the pan first; don’t rely on the oven time to finish it.
Can I make this in a regular pie dish instead of a casserole dish?
A standard 9-inch deep-dish pie plate works fine. A shallow dish will make the pie thinner and may need 5 fewer minutes in the oven, so start checking earlier.
Can I swap the ground beef for ground turkey or chicken?
Yes, but ground poultry must reach 165°F (74°C) internally — higher than beef — so make sure it’s fully cooked through in the pan before assembling. The flavor will be milder, so consider adding an extra pinch of basil or a little garlic powder to compensate.
