If you grew up in America, Mac and cheese is pretty much the definition of childhood nostalgia.

Although I enjoyed many home-cooked meals, I also deeply loved good ole’ Kraft mac and cheese. My favorite was the shaped pasta. For some reason, it tasted better than the regular macaroni noodles. And we can’t forget the glaringly neon orange cheese powder that you’d rehydrate with milk and pour over the cooked pasta with a pat of butter.

This vegan butternut squash mac and cheese is kind of like the grown-up version of that once beloved pasta with a dairy-free, seasonal twist. Its hue is naturally orange from the squash and the ingredients are rather simple yet give it a complex flavor.

Ingredients

The best part? 95% of this recipe is made with capsule pantry ingredients. This is what I used:

  • Pasta – I suggest using any type of smaller-shaped pasta noodles such as elbows, shells, ziti, fusilli, rigatoni, etc. Use gluten-free noodles if needed.
  • Butternut squash – contributes to the creaminess, flavor, and orange color.
  • Raw cashews – they make dairy-free sauces extra creamy and velvety.
  • Plant milk – I love oat milk, but you can use whatever kind of dairy-free milk you like.
  • Reserved pasta water – the starch in the water helps create a more cohesive and creamier sauce.
  • Miso paste – this is the secret ingredient that adds the complexity that cheese has.
  • Nutritional yeast – gives it a slightly cheesy, umami flavor.
  • Lemon juice – cuts through the richness and adds some tang.
  • Dijon mustard – gives the sauce a sharp, tangy flavor.
  • garlic & onion powder – give it a savory flavor.
  • Smoked paprika – adds a nice smokiness.
  • Nutmeg – used in traditional bechamel sauce (a French, dairy-based sauce) to elevate the overall flavor.
  • Kosher salt & freshly cracked black pepper – to taste.

How to Make Vegan Butternut Squash Mac and Cheese

Roast the squash. Peel the butternut squash and cut it into cubes until you have 2 cups, toss with a little olive oil, kosher salt, and black pepper. Spread them out into a single layer on a lined baking sheet and roast until fork-tender, about 25 minutes.

Cook the pasta. When the squash is halfway done, cook the pasta in a pot of salted water according to the package directions. Keep warm and set aside.

Make the butternut sauce. Add all the ingredients to a blender and blend until smooth and creamy. Taste, and add more salt, pepper, or lemon juice as needed.

Assemble mac and cheese. Add the butternut sauce to the pasta and stir to combine.

How can you make this vegan butternut squash mac and cheese using what you already have? Here are some ideas

Frequently Asked Questions

What does butternut squash mac and cheese taste like?

It’s ever so slightly sweet and nutty because of the roasted butternut squash, yet still savory because of the addition of other seasonings.

Do you need to peel butternut squash?

For this recipe, yes. We want the sauce as smooth and creamy as possible, so be sure to peel the skin of the squash before you roast it.

Can you use canned butternut squash or pumpkin puree instead of fresh?

You can, but roasting the butternut squash adds more flavor to the sauce.

How can I prevent the sauce from drying out?

Only add the sauce to the pasta noodles if you’re going to eat them right away, otherwise, they’ll dry out.

How long will it keep?

Store the sauce and cooked pasta separately in an airtight container for up to 5 days. Reheat in the microwave or on the stovetop. If you’ve already mixed the pasta and sauce, you may need to add a splash or two of plant milk before reheating to rehydrate it.

    Absolutely killer! I had been looking forward to making this for a large group of people. Went to the grocery store with my list only to find no butternut squash. When I inquired about it, I was directed to some bagged, pre peeled, cubed squash. I wasn’t exactly excited by that but it was my only option. Turns out it worked perfectly well. And this pasta did not disappoint! I’m delighted that I doubled the recipe and I have some leftover to relive the taste. I followed Lindsey’s suggestion of keeping the sauce and the pasta separate and it heated really well when I combined them just before placing them in the microwave. Thanks for another incredible recipe! And by the way, I am not vegan but prefer this to “regular” Mac and cheese!!
