Ingredients for Vegan Mac and Cheese

The perfect butternut squash mac and cheese begins with a combination of key ingredients that build creamy, cheesy flavor. 

I recommend using fresh butternut squash when you can, but there are actually a few substitutions that work just as well. You can also swap in a 15 ounce can of butternut squash or pumpkin puree. Frozen butternut squash chunks from the grocery store or your freezer work just as well too. 

If you opt for the canned puree, just make sure you’re choosing pure pumpkin puree, not pumpkin pie filling. The pie filling has a lot of spices and sugar that clash with this recipe.

To make this you’ll need:

  • Butternut squash, cooked or frozen, or one 15 ounce can of puree
  • Raw cashews, soaked overnight
  • Nutritional Yeast
  • Prepared Mustard
  • Onion Powder
  • Smoked Paprika
  • Nutmeg
  • Sea Salt
  • Black Pepper
  • Lemon Juice, fresh
  • Coconut Milk
  • Cooked Pasta, of choice, rigatoni or macaroni work great

If you have the time, I highly recommend roasting your butternut squash cubes first. This draws out a lovely caramelized flavor from the squash’s natural sugars and adds a depth to your sauce. 

You can even roast frozen butternut squash. Just place frozen cubes on a parchment or silpat lined baking sheet and roast at 425°F until you see it begin to caramelize, about 20 minutes. 

How many butternut squashes do I need if I want to use fresh squash?

For 2 full cups after peeling and seeding your squash, look for one 1 ½ pound to 2 pound butternut squash. You should get anywhere from 2 to 3 cups. 

However, if you’re looking to save time later, prep extra and freeze it for another night when you’re craving squash mac and cheese.

How to Make Squash Mac and Cheese

With a creamy sauce that comes together in the time it takes your pasta to cook, this is an easy and flavorful weeknight meal. To get started, get your high powered blender out and ready to go. 

Begin by bringing a salted pot of water to boil for your pasta. Follow the pasta’s package instructions for cooking times.  While you do that, prepare your sauce. 

Combine your cooked butternut squash, soaked and drained cashews, and all other ingredients into your blender. Blend on high until the sauce is smooth and creamy. This took about 2 minutes for me, but may take a little longer in your blender.

Taste your sauce and if needed, add more salt, pepper, or other spices to suit your tastes. I definitely recommend using smoked paprika if possible, it builds a nice but subtle smoky flavor that compliments the squash.

If you forgot to soak your cashews overnight, you can always soak them quickly for 30 minutes in boiling water before making your sauce. Just be sure to drain them well before using them. 

Once your pasta is cooked to al dente, drain it and return it to the pan. Pour the creamy squash cheese sauce on top and stir it over medium heat until well combined and hot. 

I always find that reserving a tablespoon of pasta water to add to the sauce while heating is a great way to help the sauce cling to the pasta and thicken beautifully. 

Serve immediately and enjoy! You just made a butternut squash mac and cheese vegan masterpiece in about 15 minutes.

Jazzing up your Mac and Cheese

I can guarantee that a bowl of this vegan mac and cheese is satisfying as it is. Butternut squash is creamy, full of nutrients, and delicious. 

But sometimes, I like to change things up. Here are a few ways to make this different from time to time. 

  • Roast your squash with some add paprika or herbs to infuse it with flavor. 
  • Add a teaspoon or two of roasted garlic to your sauce.
  • Add sautéed or roasted kale, spinach, peppers, or broccoli to your finished dish for added bursts of veggies. 
  • Transfer your butternut squash mac and cheese to an oven safe pan or dish and top with breadcrumbs that have been tossed with oil, salt, and pepper. Bake until the breadcrumbs are toasted and enjoy.

How to Store Leftovers

If you have any pasta left or decide to make extra for an easy meal later in the week, vegan mac and cheese stores well in the fridge. Simply store it in an airtight container in the fridge for up to five days. 

You can also freeze this in any freezer-safe, airtight container for up to 3 months. To prepare from frozen, allow it to thaw in the fridge then reheat gently on the stovetop and serve warm. 

When reheating your squash mac and cheese, you may find that you need to add a splash of non-dairy milk or water to help the sauce loosen up. Taste and adjust seasonings if you do this, and serve as usual.

This cheesy-tasting vegan mac is the perfect comfort food for fall. Since it’s full of winter squash, it’s a healthy and guilt-free even your kids will beg for. Better yet is how fast you can whip up this meal when you simply would rather not cook. It’s my go-to savory cheese sauce for the fall and winter.
