Best of all, this recipe is adaptable—add cooked chicken, sausage, or extra cheese to customize it to your taste. Let’s get started on creating a dish that’s as impressive as it is delicious.

Ingredients for alfredo spaghetti pie

Sixteen ingredients for a pie that delivers restaurant-quality creaminess with crispy tortilla perfection.

The tortillas are the foundation—Mission brand or La Tortilla Factory low-carb tortillas work best for that ideal crisp. Look for ones with minimal ingredients—just flour, water, and salt. The Parmesan must be freshly grated; pre-shredded contains anti-caking agents that prevent proper melting. For the alfredo sauce, European-style butter (like Plugrá) adds more flavor than regular butter, but any high-quality unsalted will do. Shallots are key here—they add sweetness without overpowering the garlic.

No heavy cream? Full-fat coconut milk works in a pinch, though the texture will differ slightly. Substitute mozzarella with fontina or Gruyère for deeper flavor. The nutritional yeast can be omitted if you're avoiding it, but it's worth the 2 tablespoons for that cheesy umami punch. For a lighter crust, brush the tortillas with olive oil instead of butter before baking. The spaghetti should be broken into 3-inch pieces—longer strands won't bake evenly, and shorter ones risk turning mushy.

Assemble the pie up to 24 hours ahead and refrigerate—it actually tastes better the next day as flavors meld. Store leftovers in an airtight container for 4 days in the fridge, or freeze portions for 3 months. Reheat covered at 350°F for 15-20 minutes to restore crispiness. The tortillas lose crispness when reheated, so enjoy straight from the oven whenever possible.

Step-by-step instructions for alfredo spaghetti pie

Here's how to build layers of rich alfredo and crispy tortilla perfection.

Melt the 0.75 cup unsalted butter in a saucepan over medium heat until foaming. Add the 2 whole shallots and 4 cloves minced garlic, cooking for 3-4 minutes until softened and fragrant—just until the garlic loses its raw bite but doesn't brown. This ensures sweetness without bitterness.

Pour in the 1.5 cups heavy cream and bring to a gentle simmer. Immediately reduce heat to low and whisk in the 1.5 cups freshly grated parmesan cheese and 2 tablespoons nutritional yeast until completely melted and smooth. The sauce should coat the back of a spoon with a velvety consistency. Season with 0.75 teaspoon kosher salt and 0.25 teaspoon black pepper, then remove from heat and set aside.

Break the 12 oz spaghetti into 3-inch pieces by hand for even baking. Cook in boiling salted water until al dente—about 2 minutes less than package instructions. Drain immediately and toss with 1 tablespoon olive oil to prevent sticking.

In a large bowl, combine the cooked pasta with half of the alfredo sauce, 4 oz shredded mozzarella, and 0.5 teaspoon kosher salt. Mix gently but thoroughly to distribute the cheese evenly. The pasta should be coated but still hold its shape when pressed—this ensures proper layering without mushiness.

Preheat oven to 375°F. Brush a 9x13-inch baking dish with 1 tablespoon olive oil, then arrange 4 large flour tortillas in a single layer at the bottom, overlapping slightly. Brush the tortillas with remaining olive oil and sprinkle with 0.5 teaspoon kosher salt and 0.25 teaspoon black pepper.

Spread the pasta mixture evenly over the tortillas, creating a single even layer. Top with remaining alfredo sauce, spreading it to the edges. Sprinkle the remaining 4 oz shredded mozzarella evenly over the top. The crust should be fully covered but not buried under cheese.

Bake uncovered for 25-30 minutes until the tortilla crust is deep golden brown and the edges are crispy. If the top browns too quickly, loosely tent with foil for the last 10 minutes to prevent over-browning while finishing the crust.

For the final touch, remove from oven and drizzle with the 0.25 cup heavy whipping cream immediately after baking. The cream will create a glossy, creamy finish that seals in moisture. Let rest for 5 minutes before slicing—this ensures clean cuts and prevents the filling from sliding out.

Cut into squares and serve immediately while the crust remains crispy. Each bite should deliver the contrast of crunchy tortilla against the creamy alfredo and tender pasta. For extra crispiness, broil for 1-2 minutes before serving if the crust softens during resting.

Pair with a simple arugula salad dressed with lemon vinaigrette to cut through the richness. The pie holds well for 3 days refrigerated, but the crust loses its crispness—best enjoyed fresh from the oven.

Perfect pairings for this recipe

Creamy Sauce Balance

Pair this alfredo spaghetti pie with a bright, acidic side to cut through the richness.

I love a simple arugula salad tossed with 2 tbsp lemon vinaigrette—just 3 tbsp extra-virgin olive oil, 1 tbsp fresh lemon juice, ½ tsp Dijon mustard, and a pinch of flaky sea salt. The peppery greens and citrus balance the creamy filling perfectly. 🥗

Crunchy Additions

For extra texture contrast, serve with toasted breadsticks or garlic knots on the side. Brush warm breadsticks with garlic-infused olive oil and sprinkle with parmesan cheese before baking at 400°F for 8-10 minutes. The crispy, cheesy bites complement the pie’s tortilla crust beautifully.

Light Beverage Pairings

A crisp Italian white wine like Pinot Grigio or Vermentino enhances the dish’s creamy, cheesy flavors. For non-alcoholic options, try sparkling water with a splash of lemon or iced hibiscus tea—both refresh the palate between bites. Avoid heavy reds that would overpower the delicate alfredo. 🍷

Sweet Contrast Finish

End the meal with a light dessert like lemon sorbet or dark chocolate-dipped strawberries. The tartness of the sorbet or the bitterness of dark chocolate cleanses the palate after the rich pie. For a quick option, serve vanilla bean ice cream with a drizzle of honey—simple but effective.

Protein Boost Options

If you want to add protein, serve with grilled chicken tenders or prosciutto-wrapped asparagus. The smoky, savory notes of prosciutto elevate the dish without competing with the alfredo. For a vegetarian option, mushroom risotto adds earthy depth that pairs wonderfully with the pie’s creamy layers. 🍗

Make-Ahead Serving Tips

If assembling ahead, refrigerate the unbaked pie for up to 24 hours—it actually tastes better the next day. Reheat at 350°F for 15-20 minutes to restore crispiness.

For a crowd, serve with individual tortilla cups filled with extra alfredo and mozzarella for dipping. This keeps the pie’s signature flavors intact while offering variety. 💡
