Why We Love Pumpkin Alfredo

I am a huge fan of Alfredo, but I usually enjoy it sparingly it since it’s definitely an indulgence. The classic sauce calls for 2 cups of heavy cream and a whole stick of butter (yikes!).

This Pumpkin Alfredo recipe uses only two-thirds of a cup of half and half (half milk, half cream) and 6 tablespoons of butter. The addition of the pumpkin gives the same velvety smooth texture of cream, without the fat and calories.

It’s velvety and smooth and rich and with less than a quarter of the cream and less butter than classic Alfredo sauce. So not only does it taste amazing, but you won’t even miss the cream or butter!

Since pumpkin has such a neutral taste it’s the perfect substitution, which is why I’m always on the hunt for new pumpkin recipes! Plus, you can customize the sauce by adding veggies or protein, like mushrooms, baby spinach or chicken.

How to Make Pumpkin Alfredo

The sauce is super simple to make. The sauce is made quickly while the pasta is cooking and then the pasta is tossed with the sauce. The whole thing is done in less than 15 minutes!

Tools needed (affiliate links): 12″ saute pan, Stockpot, Whisk

  • Use the stockpot to cook the fettuccine pasta according to the package instructions. Drain, reserving about a cup of the pasta water for the sauce.
  • While the fettuccine is cooking, melt butter and stir in some minced garlic (I use jarred for ease and simplicity) in a large skillet over medium heat. Once the garlic begins to smell delicious (it doesn’t take long), pour in the half & half, pumpkin, Parmesan cheese and a pinch of nutmeg. Whisk it all together with the butter and garlic until the cheese is melted.
  • I added about half of a cup of the pasta cooking water to thin out the sauce a bit since the pumpkin is a little on the thicker side. Simmer for a few minutes. You can add as much or as little of the pasta water as you like until the sauce is to your desire consistency.
  • Finally, toss the pasta with the sauce until well coated.
  • This dish makes about 4 servings and it’s perfect for company or just when you need an easy weeknight meal this fall. I like to add fresh minced parsley on top for color and freshness.

Serving Suggestions

Because of its mild, slightly nutty flavor, this dish will pair well with lots of dinnertime favorites, from baked chicken to baked pork chops. It would be delicious tossed with some Parmesan Baked Shrimp, too!

For a meatless meal, serve with Sauteed Mushroomsroasted broccoliGarlic Green Beans or just a copycat Olive Garden Salad.

What to Do With Leftovers

Storage: Store leftovers in an airtight container in the fridge for up to 2-3 days.

Reheating: For just the sauce, reheat in a small saucepan over medium-low heat. If you’ve stored the leftovers mixed with pasta, you can reheat in a saucepan or in the microwave for about 60 seconds. If it’s too thick, add a little bit of milk or water to thin it out.

Two plates of pumpkin alfredo
  • You definitely want to use fresh Parmesan, grated off the block for this alfredo recipe. The canned grated cheese will not melt properly and will make your sauce lumpy.
  • Instead of using butter, feel free to use olive oil for sauteing the garlic.
  • Make it vegan – use a non-dairy milk alternative, like cashew milk or oat milk and a non-dairy Parmesan cheese.
  • Any kind of pasta will work, from long noodles like spaghetti or linguine, to smaller cuts like rotini or penne.
  • Try adding some sage, rosemary or thyme with the garlic. Saute, then remove just before adding the pumpkin and cream.

Total Time 20 minutes
Servings 6 servings


  • 1 pound fettuccine cooked to al dente, reserve 1 cup of pasta water
  • 6 tablespoons butter
  • 2 garlic cloves minced
  • 1 cup pumpkin puree not pie filling
  • 1/8 teaspoon nutmeg
  • 2/3 cup half & half
  • 1/2 cup freshly grated Parmesan cheese off the block
  • 1 tablespoon fresh chopped parsley


  • Bring a stockpot of water to a boil over high heat. Add a teaspoon of salt to the boiling water, then add fettuccine. Cook until al dente (check package instructions). Reserve about 1 cup of the pasta water.
  • Meanwhile, melt butter over medium-low heat. Stir in garlic and cook for about a minute, careful not to burn. Stir in half & half, Parmesan, pumpkin and nutmeg. Stir until sauce is heated through and cheese is melted. Stir in pasta water, about ¼ cup at a time, until sauce is desired consistency (I used about ½ a cup, and it was thick and creamy. For a thinner sauce, use more pasta water).

  • Divide into bowls and garnish with fresh chopped parsley and fresh grated Parmesan, if desired.

  1. I had pumpkin left over after making a cheesecake, so decided to try this recipe. It was simple to make (perfect for a weekday meal) and came out sooo good! I will definitely make this again and again.

  2. Absolutely loved this recipe wow!! Perfect for fall, I doubled this recipe for a group and it was a hit!!! I did add about 1/4th tsp of pumpkin pie spice to add some more fall flavor in! A keeper of a recipe for sure!!!

  3. My family really liked this dish with some sliced sausage. My husband has to have some kind of meat in his meals. I did have to add a little extra seasoning and cheese. Other than that, I love the idea of using pumpkin. Even my mini me who is a very picky eater enjoys this dish.

  4. I just made this for dinner tonight but used spaghetti instead and it’s yummy but I have some sauce leftover do you think I could freeze the sauce to use for another batch?

    1. Unfortunately alfredo sauce doesn’t freeze well. You could try it though, I just don’t have high hopes that it will work well.

  5. I have made this several times but always need to tweak it a bit, there just isn’t enough flavor….added salt and pepper, extra Parmesan, dash of smoked paprika and extra pumpkin, delicious!

    1. Because of the cheese sauce, I would eat it right away. You can refrigerate leftovers and reheat in the microwave at 50%, but use up within a couple of days.

  6. This looks so good! What a fun way to switch up a pasta option when company comes over! Are there any meats that go well with it?

  7. This dish is delicious! I made it tonight for dinner, it only took 20 minutes to make and my boyfriend and I both love it. I’m calling this my “pumpkin redemption dish” because I’ve wanted to learn a good pumpkin recipe after a pumpkin ravioli disaster last year.

    1. Thank you Brianna! Loved your Phrase “pumpkin redemption dish” Thank you for stopping by and leaving your positive feedback.

    1. I’m sorry, I haven’t made this in the IP so I don’t have a recommendation. I imagine it would be similar to any other ip alfredo recipe that you google.
