Getting together the ingredients for this Spaghetti Pie Casserole Recipe is easier than you might think. Each one plays an important part in building layers of flavor and texture — from the silky butter coating the pasta to the robust tomato-meat sauce bubbling beneath the cheese.

6 ounces spaghetti: The foundation that will become a crispy, flavorful crust.

2 tablespoons salted butter: Adds richness and helps bind the spaghetti together.
1/2 cup grated parmesan cheese: Imparts a salty, nutty depth that enhances every bite.
2 large eggs, well beaten: Acts as a natural binder to hold the spaghetti crust firm.

½ pound ground beef: Delivers hearty, savory flavor to the sauce layer.
½ pound Italian sausage: Brings a little spice and complexity to the meat mixture.
¼ cup finely diced onion: Adds sweetness and aroma as it cooks down in the sauce.

1 teaspoon minced garlic: Pungent and fragrant, it rounds out the sauce seasoning.
14.5 ounces petite diced tomatoes, undrained: Provides juicy texture and bright tomato flavor.
6 ounces tomato paste: Concentrates tomato richness and thickens the sauce.

1 teaspoon granulated sugar: Balances acidity in the tomatoes for a smoother taste.
1 teaspoon crushed oregano: Adds an earthy, herbal note characteristic of Italian flavors.
½ teaspoon garlic salt: Combines saltiness with extra garlic kick to season perfectly.

1 cup whole milk small curd cottage cheese: Gives a creamy, mild layer that contrasts beautifully with the sauce.
1 cup shredded mozzarella cheese: Melts to a golden, bubbly finish binding everything together.

How to Make Spaghetti Pie Casserole Recipe

Step 1: Prepare the Pie Plate and Cook Spaghetti

Start by greasing a 10-inch pie plate with cooking spray so your pie crust releases easily after baking. Preheat the oven to 350º Fahrenheit—it’s important to have it ready for later. Cook the spaghetti according to the package directions until al dente, then drain it well. This ensures your crust forms nicely without being soggy.

Step 2: Form the Spaghetti Crust

While the pasta is still warm, toss it with the butter until fully melted. This step adds luscious flavor and helps the noodles stick together. Next, stir in the grated parmesan and beaten eggs, mixing thoroughly to bind the crust. Press this mixture firmly into the bottom and sides of your pie plate, shaping a spongy, golden base that will hold the filling.

Step 3: Make the Meat Sauce

In a skillet set to medium heat, brown the ground beef, Italian sausage, and diced onions until the meat is cooked through and the onions are tender. Drain any excess fat to keep the sauce from being greasy. Add the minced garlic and immediately stir in the diced tomatoes with their juice, tomato paste, sugar, oregano, and garlic salt. Reduce heat to medium-low and simmer the sauce until all the flavors meld and it’s heated through properly.

Step 4: Assemble the Casserole

Spread an even layer of cottage cheese over your spaghetti crust—it creates a creamy buffer between pasta and meat that’s positively dreamy. Then pour the warm meat sauce over the top, spreading it gently so it fills the pie evenly. Place the pie plate in the oven and bake for 20 minutes, letting everything meld and bubbles entice from the edges.

Step 5: Add Mozzarella and Finish Baking

After the initial bake, sprinkle shredded mozzarella over the top and return the casserole to the oven. Bake for another 5 to 10 minutes until the cheese is melted and bubbling beautifully. For an irresistible golden-brown finish, place the pie briefly under the broiler for 2 to 4 minutes, watching closely so the cheese doesn’t burn. This final touch adds a crispy, cheesy cap that’s hard to resist!

Garnishes

Keeping it simple works best here: a sprinkle of fresh basil or chopped parsley brings a bright pop of color and a hit of fresh flavor. Grated parmesan on top just before serving can add another layer of salty goodness. A sprinkle of red pepper flakes also works wonders if you like a little heat.

Side Dishes

This dish is a full meal on its own, but pairing the Spaghetti Pie Casserole Recipe with a crisp green salad or roasted seasonal vegetables adds balance and freshness. Garlic bread or warm focaccia makes for an irresistible side to mop up any leftover sauce. A light, citrusy vinaigrette on your salad will contrast beautifully with the casserole’s richness.

Creative Ways to Present

Slice the spaghetti pie like a pizza wedge to keep that charming pie look, serving individual portions on colorful plates. For a casual party, consider making mini versions in muffin tins—everyone loves personal pies! You can also layer additional veggies or swap out cheeses for different flavors, customizing it to suit your mood or what’s in your fridge.

Make Ahead and Storage

Storing Leftovers

Leftovers of the Spaghetti Pie Casserole Recipe keep well when stored in an airtight container in the refrigerator. They will stay tasty and moist for up to 4 days, making it perfect for weekend meal prep or a quick dinner after busy days.

Freezing

This casserole freezes wonderfully! Wrap it tightly with plastic wrap and foil to avoid freezer burn, then freeze for up to 3 months. When you’re ready to enjoy it again, thaw overnight in the fridge before reheating to keep the texture just right.

Reheating

To reheat, place individual slices on a microwave-safe plate and warm for 1 to 2 minutes or until hot. For a crispier top and edges, reheat leftovers in a 350º Fahrenheit oven for 15 to 20 minutes. This returns some of the fresh-baked magic to your Spaghetti Pie Casserole Recipe.
