Pumpkin Alfredo Pasta with Sage Walnut Crispies
This pumpkin alfredo pasta is the fall dinner I look forward to making every single year and the one that genuinely surprises people when they taste it. The pumpkin disappears into the Alfredo sauce and becomes this rich, slightly sweet, deeply savory cream sauce that coats every piece of rigatoni and tastes like autumn in a bowl. And then the sage walnut crispies go on top, and suddenly you have a pasta dish that looks and tastes like something from a really good restaurant.
Why You’ll Love This Recipe
Thirty minutes and one skillet for the sauce. The whole dinner comes together faster than most weeknight pasta recipes and with a finished result that tastes genuinely special.
Pumpkin puree stirred into a classic Alfredo base adds a natural creaminess and a subtle sweetness that makes the sauce taste more complex and more interesting than a plain cream and Parmesan sauce.
This is an impressive enough dinner to serve to guests and an easy enough recipe for a regular fall weeknight.

Ingredients Needed to Make Pumpkin Pasta
The Pumpkin Alfredo Sauce
Unsalted butter, a finely chopped shallot, and minced garlic build the aromatic base. Pumpkin puree adds the natural sweetness and body of the sauce. Chicken or vegetable broth loosens the pumpkin base before the cream goes in. Heavy cream adds the rich, silky Alfredo character. Freshly grated Parmesan melts into the sauce and adds the salty, nutty depth. A pinch of nutmeg adds a warmth that pairs specifically well with pumpkin. Reserved pasta water adjusts the final consistency.
The Sage Walnut Crispies
Finely chopped walnuts toasted in melted butter until fragrant then finished with fresh chopped sage, brown sugar, salt, and pepper. The brown sugar caramelizes around the walnuts as they cook and produces a slightly sweet, slightly crunchy, intensely savory and herby topping that is completely unlike any standard pasta garnish.

How to Make Creamy Pumpkin Alfredo Pasta
Step 1: Make the Crispies First
Heat a skillet over medium-low. Toast the walnuts in melted butter for 2 to 3 minutes. Add the sage, brown sugar, salt, and pepper and stir constantly for 1 to 2 more minutes until caramelized and fragrant. Transfer immediately to a plate to cool. Do not leave them in the hot pan or the sugar will continue cooking and burn.
Step 2: Cook the Pasta
Boil the pasta in generously salted water until al dente. Reserve a full cup of pasta water before draining.
Step 3: Build the Sauce
Melt the butter in a large skillet over medium-low. Cook the shallot until soft then add the garlic for 30 seconds. Add the pumpkin puree and broth and simmer for 2 to 3 minutes. Reduce to low and stir in the cream, Parmesan, salt, pepper, and nutmeg. Cook gently for 2 to 3 more minutes until smooth and slightly thickened. Keep the heat low throughout.
Step 4: Combine
Add the drained pasta to the sauce and toss until every piece is coated. Add pasta water a few tablespoons at a time until the sauce is silky and the right consistency. Taste and adjust seasoning.
Step 5: Serve
Divide into bowls and top generously with the sage walnut crispies. Extra Parmesan and cracked black pepper over the top.
Storing and Reheating
Store in a sealed airtight container in the refrigerator for up to 4 days. Store the sage walnut crispies separately in a small container at room temperature so they stay crispy. The sauce thickens significantly as it cools. Add a splash of broth or cream when reheating and stir over medium-low heat until smooth. Microwave on medium power in 60-second intervals with a small splash of liquid. Add the crispies fresh after reheating.

Serving Suggestions
Serve immediately in wide shallow bowls with the sage walnut crispies piled generously on top. Extra Parmesan grated over the top and a few whole fresh sage leaves fried in butter for 30 seconds as an additional garnish makes this look stunning. A simple arugula salad alongside adds a peppery, slightly bitter contrast that cuts through the richness of the cream sauce beautifully

Pumpkin Alfredo Pasta with Sage Walnut Crispies (Easy Fall Recipe)
Method
- Heat a skillet over medium-low heat.
- Add the melted butter and chopped walnuts. Cook for 2–3 minutes, stirring frequently, until the walnuts are lightly toasted and fragrant.
- Add the chopped sage, brown sugar, salt, and black pepper. Continue cooking for 1–2 minutes, stirring constantly, until the sage is fragrant and the walnuts are lightly caramelized.
- Immediately transfer the walnut mixture to a plate and spread it into an even layer to cool and crisp up.
- Watch the mixture closely once the sugar is added—it can burn quickly.
- Bring a large pot of generously salted water to a boil. Cook the pasta according to the package directions until al dente.
- Before draining, reserve at least 1 cup of pasta water.
- While the pasta cooks, melt the butter in a large skillet or sauté pan over medium-low heat.
- Add the shallot and cook for 2–3 minutes, until softened.
- Add the garlic and cook for about 30 seconds, just until fragrant. Be careful not to brown it.
- Stir in the pumpkin puree and broth. Simmer for 2–3 minutes, stirring occasionally, until smooth and heated through.
- Reduce the heat to low and stir in the heavy cream, Parmesan, salt, black pepper, and nutmeg.
- Cook for another 2–3 minutes, stirring frequently, until the sauce is smooth and slightly thickened. Avoid boiling the sauce after adding the cream.
- Add the drained pasta directly to the skillet with the pumpkin Alfredo sauce.
- Toss until the pasta is evenly coated. Add reserved pasta water, a few tablespoons at a time, until the sauce reaches a smooth, creamy consistency that coats the pasta without being too thick.
- Taste and adjust the salt and pepper as needed.
- Divide the pasta among bowls and top generously with the sage walnut crispies.
- Finish with additional Parmesan and freshly cracked black pepper, if desired.
- For extra protein, serve with sliced grilled or roasted chicken.
Notes
- Use pumpkin puree, not pumpkin pie filling. Pumpkin pie filling contains added sugar and spices and will change the flavor of the sauce.
- Freshly grated Parmesan works best: It melts more smoothly into the sauce than pre-shredded Parmesan.
- Don’t boil the Alfredo sauce: Keep the heat low once the cream and Parmesan are added to help prevent the sauce from becoming grainy.
- Save your pasta water: The starchy water helps loosen the sauce and gives it a silky, glossy texture.
- Adjust the consistency: The sauce will thicken as it sits. Add a splash of pasta water when reheating or if the sauce becomes too thick.
- Watch the walnut crispies: The brown sugar caramelizes quickly. Keep the heat at medium-low and stir frequently.
- Pasta options: Rigatoni works especially well because the sauce gets caught inside the tubes, but penne, shells, fettuccine, or bow ties would also work.
- Add chicken: For a higher-protein meal, top with sliced grilled chicken, roasted chicken, or leftover rotisserie chicken.
- Make it vegetarian: Use vegetable broth instead of chicken broth.
