This Vegan Pumpkin Alfredo Cheese Sauce Recipe is perfect for everyone!
No matter if you’re vegan or vegetarian or meat-eater because everyone will love this healthy dairy-free cheese sauce! Since it’s much healthier than real cheese, you can also make it when you want to reduce calories in your diet. Even if you’re avoiding carbs like pasta, this Pumpkin Alfredo cheese sauce is perfect because it’s very versatile and also delicious to serve over vegetables!
Simple & healthy Ingredients
This Vegan Pumpkin Alfredo Sauce recipe is originally adapted from my classic vegan mac and cheese sauce while there are a few swaps and options. It’s mainly just made of pumpkin (no potatoes) and non-dairy milk but the flavors of roasted garlic and nutritional yeast are still an important part of this dairy-free cheese sauce! I also like to some warming fall spices like nutmeg or pumpkin spice but you can vary the seasonings to your desired taste!
Which non-dairy milk can I use?
You can pretty much use any non-dairy milk based on your personal nutrition and taste. If tolerating nuts, I suggest using creamy cashew milk or almond milk because they’re relatively neutral in taste. For a nut-free vegan alfredo cheese sauce, I suggest using oat milk or soy milk or coconut milk. However, also another non-dairy milk like hemp or sunflower seed will do! Just make sure to use a pretty rich and no watery milk if you want a super creamy sauce!
Make your own non-dairy cream!
I often find non-dairy milk in the supermarket which is very expensive and has high water content, about 90%! So I prefer making my own dairy-free milk because it’s not only cheaper but I also want to be sure that it contains no added flavors or sweeteners. Besides this, homemade non-dairy milk or cream is also very easy to make! Just blend up soaked nuts (or seed butter if nut-free) with water and that’s it! What I also love is that you can vary the amount of water. So adding less water for a rich and creamy milk or adding water more to thin.
How to make Vegan Pumpkin Alfredo Sauce
Step 1: Make Pumpkin or squash purée
For this recipe, you’ll need pumpkin purée or butternut squash purée. I prefer making my own homemade pumpkin purée by roasting a Hokkaido pumpkin (also known as “Red Kuri Squash”) in the oven as directed in this recipe or this recipe. However, you could also cook the pumpkin or squash on the stove or in the microwave as instructed here.
Can I use canned pumpkin purée?
If you don’t have much time you can definitely use canned pumpkin purée as mentioned in the recipe notes. Anyway, I still recommend roasting a whole smaller pumpkin or squash in the oven because this gives the sauce the most richness, creamiest consistency, and best flavorful taste!
Step 2: Blend all the ingredients into a creamy cheesy vegan sauce!
Once you’ve cooked the pumpkin or butternut squash and have all the remaining ingredients prepared, just blend everything into a creamy and smooth vegan Alfredo cheese sauce! If making your own non-dairy milk or cream with whole nuts or seeds I suggest using a high-speed blender for the creamiest and smoothest result. But if using store-bought non-dairy milk or nut butter, it’s totally fine to use a simple stand mixer or immersion stick blender.

- Nut-free (optional)
- Can be made Gluten-free
- Loaded with Pumpkin

Use any pasta or gluten-free noodles!
While traditional Mac and Cheese is often served with Maccaroni and Carbonara with Spaghetti, most people serve the classic Alfredo Sauce with Fettuccine Pasta. Anyway, I don’t always follow this tradition because the pumpkin sauce is delicious with any pasta, especially with Homemade Pasta! By the way, have you tried my healthy and gluten-free spiralized veggie noodles yet? They would be also perfect to serve with this BEST creamy Pumpkin Alfredo Sauce if you’re looking for a healthier low-carb option! Also, sweet potato noodles or squash noodles or Gnocchi or Ravioli are a great choice!
What else can I serve with vegan Pumpkin Cheese Sauce?
As mentioned before, this dairy-free sauce is not only perfect for pasta but also to serve as vegan cheese sauc! To make the sauce “cheesier” and “more stretchy” I suggest adding a bit of tapioca starch, then it’s perfect to use for a vegan grilled cheese sandwich or vegan quesadillas! But I also love to use it for a crunchwrap supreme, Mexican sweet potato skins or BBQ Jackfruit Burger and Tortillas! However, you can also drizzle it just over crispy baked potato fries or use it as a dip for vegan burrito samosas. There are so many ways!

Vegan Pumpkin Alfredo PastaAuthor:
Vegan Pumpkin Sauce
- 1 3/4 cups pumpkin puree 400g, 1 small pumpkin or butternut squash*
- 1 tbsp coconut oil or vegan butter
- 2 cloves garlic or 1 tsp garlic powder
- 1/4 tsp smoked paprika
- 1/2 tsp salt or to taste
- 5 tbsp nutritional yeast
- 1 cup non-dairy milk or more as needed, *see recipe notes
- 1-2 tbsp tapioca starch optional, *see recipe notes
- 3-4 tbsp cashew butter optional, *see recipe notes
To serve (optional)
- vegan parmesan cheese
- 14 oz pasta 400g, of your choice
Prepare Pumpkin Purée
- To make homemade pumpkin purée, cook a small pumpkin or squash in the oven, or on the stove or microwave until soft as directed in this recipe.
- If serving the sauce with pasta, cook the pasta according to the packaging instructions until 'al dente'. Then drain, toss with a little oil and set aside.
Make Pumpkin Sauce
- To make the sauce, sauté the garlic in 1 tablespoon oil for a minute over medium heat, until fragrant.
- Add the soft cooked pumpkin along with sautéed garlic, smoked paprika, salt, nutritional yeast, non-dairy milk, tapioca flour*, and cashew butter* if using to a blender and blend until smooth and creamy (or use an immersion stick blender).
- Pour the sauce into a large pan and heat over medium heat, stirring frequently, until hot and slightly thickened. Taste and adjust seasonings. (If it gets too thick, add a bit more non-dairy milk to thin).
- Add cooked pasta to the sauce and toss to combine. Serve with vegan parmesan cheese and fresh basil or other toppings you like. Enjoy!
- You can either make your own pumpkin purée or use 2 cups of canned pumpkin purée.
- If you want to serve the pumpkin sauce as a vegan cheese sauce, I suggest adding the tapioca starch because it helps to make the sauce thicker and "cheesier" similar to a real cheese-sauce. But if serving with pasta you could also omit it. Alternatively, you could substitute cornflour or arrowroot starch to thicken but this won’t be as stretchy.
- You can use your favorite non-dairy milk such as almond, cashew, soy, coconut or oat milk.
- The cashew butter is an optional ingredient which makes the sauce richer and creamier. I suggest using cashew or almond butter. For a nut-free sauce, you could use sunflower seed butter, pine nuts or vegan cream cheese. If using raw nuts or seeds, please make sure to soak them in water overnight or boil for 20 minutes until slightly softened. 1/2 cup raw cashews are equal to 4 tbsp cashew butter.
