I’m a big fan of mac and cheese! That creamy cheesy sauce covered pasta is so comforting.

I usually make my Vegan Baked Mac and Cheese recipe. It’s so delicious! But I’m always looking for another vegan mac and cheese recipe. With butternut squash being in season, I thought it would be a great time to make a vegan butternut squash mac and cheese.

This mac and cheese is quick and easy to make on the stove top. It’s completely dairy free and oil free, and can even be made gluten free by using gluten free pasta.

It’s full of delicious fall flavor from the butternut squash, made creamy with some raw cashews, and gets a delicious cheesy taste from nutritional yeast.

The whole family will love it, and it’s a great way to sneak in some healthy vegetables for picky kids!

Ingredients needed for this recipe

Ingredients for butternut squash mac and cheese.
  • Pasta – you can use macaroni noodles or any other small shaped pasta such as small shells, penne, or rotini. Feel free to use whole grain pasta or gluten free pasta to meet your dietary needs.
  • Butternut squash – you can peel and cut fresh butternut squash, or save time and effort by purchasing pre-cut butternut squash. You can even use canned or frozen butternut squash.
  • Onion – yellow onion is best in this recipe, but you can also use a white onion.
  • Raw cashews – these create the creamy base for this butternut squash cheese sauce.
  • Non-dairy milk – I used soy milk, but unsweetened almond milk or oat milk should also work.
  • Nutritional yeast – this adds a cheesy flavor to the sauce. Nutritional yeast is not the same as baking yeast.
  • Garlic – for flavor.
  • Lemon juice – to add a little acidity.
  • Turmeric – for that nice yellow color as well as the amazing health benefits.
  • Paprika – you can substitute this with smoked paprika if you like a smoky cheese sauce.
  • Dijon mustard – this also helps create that cheesy flavor. You can use regular yellow mustard if you don’t have Dijon.
  • Salt and Pepper – to round out the flavor.

How to make vegan butternut squash mac and cheese

If you are using a whole butternut squash, cut it in half and remove the seeds. Then peel and cut it into cubes. To save time, you can use already peeled and cubed butternut squash from the store.

Place it, the onion, and the cashews in a medium pot of water and boil for about 15 to 20 minutes, until the squash and onions are tender. If you are using cooked butternut squash, measure the amount needed for the recipe and set it aside (do not boil it with the onions and cashews).

While the vegetables are cooking, heat a large pot of water and cook the pasta according to package instructions. Drain the pasta, return it to the pot, and set it aside.

When the onions are tender, drain the vegetables. Add all the ingredients except the pasta to a blender and blend until completely smooth.

    The ingredients picture shows dijon mustard and cornstarch but mustard and cornstarch are not listed in the recipe ingredients. The directions say to add the cornstarch but nothing about the mustard. How much cornstarch and mustard are to be added?
