Pumpkin Pasta Sauce

This creamy pumpkin pasta sauce recipe is a take on the classic alfredo sauce. A fall themed creamy pasta sauce made with seasonal ingredients.

This pumpkin pasta sauce is ultra creamy and makes for the perfect cheesy fall pasta.

It’s officially that time of year when I find myself wanting all the pumpkin recipes!

When you think of pumpkin, you may immediately think of dessert, but this recipe may change your mind on just how versatile this fall favorite ingredient is. 

If “pumpkin pasta” makes you go hmmmm, just think of it like this – it tastes pretty similar to butternut squash would in the same dish.

Ingredients to make pumpkin pasta sauce

  • heavy cream
  • freshly grated parmesan cheese
  • ground sage: sage and pumpkin are the perfect combination
  • garlic
  • onion
  • canned pumpkin: or use fresh if you have it!
  • unsalted butter
  • milk
  • rigatoni or pasta of choice: fettuccini would be fun for a fall alfredo
  • salt

This decadent sauce needs just ten ingredients and is ready in 30 minutes from start to finish.

How to make pumpkin pasta sauce

Step 1: Melt the butter in a dutch oven or large pot, then add the fresh garlic and onion. Cook over medium high heat for 8 – 10 minutes, stirring often, until onion is softened.

Step 2: Add milk, pumpkin, heavy cream, and sage, and cook over medium low heat, stirring often, until the pumpkin sauce begins to thicken, around 10 – 15 minutes.

While the sauce is thickening, cook one pound pasta of choice to al dente.

Step 3: Stir in the fresh grated parmesan cheese and stir to melt. Add in the cooked pasta (we used rigatoni) and salt to taste. Serve topped with extra fresh grated parmesan on top!

This recipe was inspired by one of my absolute favorite recipes to cook every fall – this One Pot Sweet Potato and Spinach Pasta in a parmesan cream sauce. 

The flavor of this pumpkin pasta sauce is similar to that recipe. 

Once you realize that sweet potato and pumpkin taste very similar, it opens up a whole new world of using pumpkin for savory recipes.

Can I add more veggies to this dish?

Yes, you can!

An easy addition of veggies would be to throw in some chopped fresh spinach to wilt in the last 2 minutes before serving. 

What do you serve with pumpkin pasta sauce?

Serve it over whatever your favorite pasta is – it doesn’t have to be rigatoni. Fettuccini, bowtie pasta, macaroni noodles, ziti, etc.

Salad and baked garlic bread would complement this dinner beautifully. 

How many servings does this make?

This pumpkin pasta will serve at least 6 generous main dish portions, or more if you are serving it along side other dishes.
