Ingredients for Old Chicago Spaghetti Pie

Hearty layers of pasta, savory meat, and melty cheese come together for this baked masterpiece.

The beef and cheese quality are non-negotiable. 80/20 ground chuck delivers the right fat for flavor and moisture. For cheese, Whole Foods or Costco have excellent full-fat cottage cheese. The mozzarella should be low-moisture part-skim to prevent a soggy crust. Parmesan must be freshly grated from a wedge—pre-shredded contains anti-caking agents that disrupt the melt.

Need to swap the beef? Ground turkey or Italian sausage work well (adjust seasoning if using sausage). No cottage cheese? Ricotta at a 1:1 ratio gives a similar texture. The marinara can be jarred—Rao’s or Victoria are restaurant-quality. For extra depth, brown the beef with a pinch of red pepper flakes (trust me on this one).

Assemble and bake immediately, or refrigerate the layered pie for up to 24 hours before baking. Leftovers reheat beautifully—store in the fridge for 4-5 days or freeze for 3 months. Portion before freezing for easy single servings.

Step-by-Step Instructions for Spaghetti Pie

This layered masterpiece comes together through precise preparation and assembly of every component.

Step 1: Cook and Prepare the Spaghetti Base

Cook the 8 oz Spaghetti Noodles in salted boiling water until al dente, then drain thoroughly. I press the noodles between paper towels to remove all moisture—this prevents a soggy crust.

Transfer the noodles to a bowl and toss with the 2 whole Large Eggs, 1.5 cups Cottage Cheese, 0.5 cup Parmesan Cheese, 1 tsp Dried Oregano, 1 tsp Dried Basil, and 1 tsp Salt. The mixture should look like wet sand and hold together when pressed.

Step 2: Sauté the Aromatic Meat Filling

Heat the 1 tbsp Olive Oil in a large skillet over medium-high heat. Add the 1 whole Onion (finely diced) and cook for 3-4 minutes until translucent and soft.

Add the 1 lb Ground Beef and cook until browned and crumbly, breaking it up with a wooden spoon. Stir in the 3 cloves Garlic Cloves and 0.5 tsp Black Pepper, cooking for 30 seconds until fragrant. Pour in the 2 cups Marinara Sauce and simmer for 5 minutes until thickened.

Step 3: Assemble the Layers in the Dish

Generously grease a 9-inch pie dish with the 2 tbsp Butter, ensuring all surfaces are coated. Press the spaghetti mixture evenly into the bottom and up the sides, creating a sturdy crust.

Spread the meat mixture evenly over the spaghetti base. Top with the 2 cups Shredded Mozzarella Cheese, ensuring complete coverage. The layers should be distinct but evenly distributed for consistent texture in every slice.

Step 4: Bake to Golden Perfection

Preheat your oven to 375°F. Bake the pie for 25-30 minutes until the cheese is bubbly and golden brown and the edges are set. You’ll see the center jiggle slightly—this is normal.

Let it rest for 10 minutes before slicing. This allows the layers to set and makes serving easier. The top should have a beautiful golden crust, while the spaghetti base holds its shape when cut.

Regional Styles of This Recipe

Chicago-Style Original

The Old Chicago version layers spaghetti with a cottage cheese-egg mixture to create a firm crust. They use 80/20 ground beef for rich flavor and top it with low-moisture mozzarella that browns perfectly. This is the classic preparation that started it all.

Italian-American Fusion

Some Chicago pizzerias add sweet Italian sausage to the beef for extra depth. They also mix ricotta cheese into the pasta layer for a creamier texture. The marinara often includes fennel seeds to complement the sausage.

Vegetarian Adaptation

Replace the beef with browned mushrooms and lentils for a meat-free version. Use the same cottage cheese-egg base and layer with spinach and sun-dried tomatoes. The baking time remains 25-30 minutes at 375°F. 🌱

Spicy Kick Variation

Add ½ tsp red pepper flakes to the beef while browning for heat. Some Chicago cooks also mix hot Italian sausage with the ground beef. Top with pepper jack cheese instead of mozzarella for an extra spicy finish.

Deep Dish Inspiration

Create a thicker pie by using 12 oz of spaghetti and pressing it up the sides of a deep dish pan. Layer with extra cheese between the meat and pasta. Bake for 35-40 minutes until the edges are crisp.

Quick Weeknight Version

Use pre-cooked spaghetti and jarred marinara to save time. Rao’s or Victoria brands work well. Assemble the night before and refrigerate—just add 10 minutes to the baking time when cold. ⏰
