Ingredients for alfredo spaghetti pie
Twelve ingredients, twelve layers of creamy perfection—your no-bake masterpiece starts here.
| Ingredient | Amount | Notes |
|---|---|---|
| Spaghetti 🍝 | 2 lbs | Cooked al dente, drained well |
| Unsalted Butter 🧈 | 1 ½ cups | Cold, cut into cubes (trust me on this) |
| Heavy Whipping Cream 🥛 | 2 cups | Full-fat for velvety texture |
| Parmesan Cheese 🧀 | 2 cups | Freshly grated from block (no pre-grated) |
| Cream Cheese 🧀 | 16 oz | Full-fat, room temperature (softened) |
| Mozzarella Cheese 🧀 | 32 oz | Fresh mozzarella, shredded (low-moisture works too) |
| Garlic Cloves 🧄 | 4 cloves | Minced for alfredo sauce (or 1 tsp garlic powder) |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal kosher salt (adjust to taste) |
| Black Pepper 🌶️ | ½ tsp | Freshly cracked for depth |
| Nutmeg 🌿 | ¼ tsp | Freshly grated for warmth |
| Fresh Basil Leaves 🌿 | ¼ cup | Chopped for garnish (optional but stunning) |
| Granulated Sugar 🍚 | 1 tbsp | Balances tangy cream cheese |
The butter and cream are your golden duo—European-style butter if you can find it, or Land O’Lakes unsalted in a pinch. Heavy cream is non-negotiable here; half-and-half will thin your sauce. For the Parmesan, Parmigiano-Reggiano from the deli counter is worth the splurge—pre-grated has anti-caking agents that ruin texture. The mozzarella? Fresh mozzarella from Trader Joe’s shreds beautifully, but low-moisture block cheese works if you're in a hurry. Pro tip: shred your own cheese—store-bought pre-shredded has additives that make it gummy. The garlic should be freshly minced (not jarred)—it makes all the difference in that alfredo sauce.
No heavy cream? Full-fat coconut cream works in a bind, though it’ll have a slight coconut flavor. Substituting Parmesan? Pecorino Romano at 1:1 ratio adds a sharper bite. Cream cheese too tangy? Mix in 1 oz cream cheese with 1 oz mascarpone for a smoother texture. The nutmeg is key—skip the pre-ground stuff and grate it fresh from a whole nutmeg. Fresh basil? Dried oregano at 1/4 the amount gets you close if you’re out. For the sugar, honey or maple syrup work 1:1, but sugar keeps it neutral. The spaghetti must be well-drained and tossed with a bit of oil to prevent clumping in the sauce.
This pie is all about patience—chill it for at least 6 hours (overnight is ideal) for clean slices. Store leftovers in the fridge for up to 5 days, covered tightly with plastic wrap. To reheat, microwave in 30-second bursts—it’ll lose its sliceability if overcooked. For parties, assemble it in the morning and let it firm up in the fridge. The layers hold beautifully, so you can even freeze it for 2 months—thaw overnight in the fridge before serving. Garnish with extra Parmesan and basil right before serving, because presentation matters—this looks like a restaurant dessert!

Step-by-step instructions for no-bake alfredo spaghetti pie
This decadent twist on classic alfredo transforms spaghetti into a creamy, cheesy showstopper—no oven required.
Prepare the Ultra-Creamy Alfredo Filling
In a large saucepan, melt the 1.5 cups unsalted butter over medium-low heat until fully liquid but not browned. Add the 2 cups heavy whipping cream and bring to a gentle simmer. Stir in the minced 4 cloves garlic, 1 tbsp granulated sugar, and 1.5 tsp salt, letting the mixture bubble softly for 5 minutes until slightly thickened.
Reduce heat to low and whisk in the 16 oz room-temperature cream cheese and 2 cups freshly grated parmesan cheese until completely smooth. The sauce should coat the back of a spoon with a velvety consistency. Remove from heat and stir in the 0.5 tsp black pepper and 0.25 tsp nutmeg. Let cool slightly—this prevents the cream cheese from melting too quickly when combined with the hot spaghetti.
Assemble the Pasta Layers
In a 9x13-inch baking dish, spread half of the cooked spaghetti in an even layer, pressing down gently with a spatula to create a firm base. Pour half of the warm alfredo sauce over the spaghetti, spreading it evenly. Sprinkle half of the 32 oz shredded mozzarella cheese over the sauce.
Repeat with the remaining spaghetti, sauce, and mozzarella, creating a second layer. The final layer should be spaghetti to ensure a clean top. Press down lightly on each layer to compact the spaghetti—this prevents a runny pie and creates that perfect sliceable texture. Cover the dish with plastic wrap and refrigerate for at least 4 hours (overnight is ideal) to allow the filling to fully set.
Chill and Garnish for Restaurant-Worthy Presentation
After chilling, run a knife around the edges of the pie to loosen it from the dish. Sprinkle the 0.25 cup chopped fresh basil leaves evenly over the top, pressing down gently so they adhere. For extra flair, use a fork to create a crisscross pattern in the mozzarella topping—this adds visual appeal and ensures every bite has a basil-infused finish.
Serve chilled or at room temperature. The pie should hold its shape when sliced, with creamy alfredo oozing slightly at the edges. For a showstopping presentation, dust with additional freshly grated parmesan cheese and serve with a side of garlic bread to soak up every last drop of that rich, cheesy goodness.

Flavor customization for this recipe
Sweet & Tangy Twist
Add a ¼ cup of apricot jam or peach preserves to the alfredo sauce for a subtle sweetness that balances the cream cheese tang. I like to simmer the jam with the butter and cream for 3 minutes before adding garlic—this creates a silky, fruity depth.
Top with toasted pecans or candied walnuts for crunch and a gourmet touch. 🍯

Frequently asked questions
Can I make this alfredo spaghetti pie ahead of time?
This is one of its best features. Assemble the pie up to 24 hours ahead and refrigerate it uncovered for the first 4 hours to help it firm up. Then cover tightly with plastic wrap and store in the fridge for up to 5 days. The flavors actually improve with time! For parties, assemble it in the morning and let it sit at room temperature for 1-2 hours before serving.
Why does my alfredo sauce get watery when mixed with spaghetti?
This usually happens when the spaghetti is too hot or the sauce isn't thick enough. Let the sauce cool slightly before mixing with the hot spaghetti, and make sure it coats the back of a spoon. For extra insurance, toss the drained spaghetti with 1 tablespoon of olive oil first to create a slight barrier. Also, press the layers firmly when assembling to compact the spaghetti and prevent sauce leakage.
What's the best way to slice this pie without it falling apart?
Chill the pie thoroughly for at least 6 hours (overnight is ideal) to ensure clean slices. Use a long, sharp chef's knife and warm it slightly by running it under hot water, then wipe it dry. Press down firmly as you cut through each layer. For extra stability, run a thin knife around the edges of the pan before removing it from the fridge to loosen the pie.
Can I make this recipe without cream cheese?
Yes, but the texture will be less creamy. Replace the 16 oz cream cheese with 12 oz mascarpone cheese or 8 oz ricotta cheese mixed with 4 oz sour cream. For a lighter version, use 1 cup Greek yogurt (full-fat) instead. The pie will still hold together, but it won't have that signature tangy richness. The nutmeg and basil will help compensate for the flavor difference.
How do I make this recipe vegetarian?
This recipe is already vegetarian-friendly! Just ensure your butter is dairy-free if needed, and use vegan cream cheese (like Tofutti) and vegan mozzarella (like Miyoko's). For the alfredo sauce, replace the heavy cream with full-fat coconut cream or cashew cream (blend 1.5 cups soaked cashews with 1.5 cups water until smooth). The texture will be slightly different but still delicious!
