Butternut Squash Mac and Cheese

By Sammi Brondo — February 16, 2026

All the amazing cheesiness of regular mac & cheese, plus the warm, fall flavors of butternut squash. This recipe is so delicious.

I’ve seen a lot of versions of butternut squash mac and cheese.

Usually, they replace the cheese entirely for butternut squash. They call it a “healthier” version of mac & cheese.

This isn’t one of those.

Because I don’t think mac & cheese needs to be replaced or made healthier. I think it’s perfectly delicious as is.

Instead, this recipe adds butternut squash to really elevate the flavor. It gives the mac & cheese a burst of warm, fall flavor. It also adds plenty of nutrients, like vitamin C and fiber.

And it’s just a fun spin on a traditional mac.

I love that this recipe is also totally family friendly too. I don’t believe in sneaking or hiding veggies into your kids’ meal – it can create negative associations.

But, I love finding fun and creative ways to use veggies and tell them about it. And this recipe definitely fits that bill.

My 2 year old loves it. I hope you and yours do too!

Prepare ingredients

You’ll need: butternut squash, vegetable broth, elbow pasta, olive oil, all-purpose flour, cheddar cheese, parmesan, garlic powder, onion powder, breadcrumbs, salt and pepper

Cook the squash

Preheat the oven to 375 F.

Bring a large pot of water to a boil. Add the chopped squash and cook for about 5-10 minutes, until fork tender.

Blend

Using a slotted spoon, place the butternut squash in a large blender (leave the boiling water on the stove as you’ll add the pasta to it soon).

Add 1/2 cup of the vegetable broth and blend until smooth. Set aside.

Prepare the sauce

Add the olive oil and flour to the pot over medium heat. Stir well to create a roux. Add the blended butternut squash to the pot and stir well. Bring to a boil and then turn the heat down to a simmer.

Cook pasta

Add elbow pasta to the boiling water and cook for about 5-7 minutes.

Add the broth & cheese

Add the remaining 1 cup of vegetable broth, cheddar cheese, 1/4 cup of the grated parmesan cheese, garlic powder, onion powder, salt and pepper to the pot. Stir constantly, until melted and smooth.

Pour over pasta

Pour the sauce over the pasta in the baking dish.

Stir gently

Stir gently so that the pasta is evenly covered by the sauce (it may look like a lot of sauce for the pasta but it will cook down!)

Prepare the breadcrumbs

In a small bowl, combine the breadcrumbs, remaining 1/4 cup parmesan cheese, salt, and pepper. Sprinkle on top of the pasta.

Bake

Bake in the preheated oven for 20-25 minutes, until the top is golden.

Garnish

Optional: top with parsley for a pop of color.

Let cool & serve

Scoop with a serving spoon and serve.

Enjoy!

Notes:

  • Butternut squash: If you can’t find fresh, frozen will work perfectly fine. Just make sure to cook it until it’s fork tender.
  • Vegetable broth: The broths adds moisture to the mac. I use a low sodium version.
  • Elbow pasta: The best traditional mac shape! You can use any other small pasta shape though too.
  • All-purpose flour: The small amount of flour in this recipe is used to create a roux that helps thicken the sauce.
  • Cheddar cheese: While it is more tedious, I highly recommend using a block of cheddar cheese and shredding yourself vs. using pre-shredded cheese. It’ll melt much better. If shredding by hand is too much of a headache, try throwing in a food processor.
  • Parmesan cheese: This adds a delicious umami, salty flavor to both the sauce and golden top.
  • Breadcrumbs: Plain breadcrumbs are great here. Panko works too and will give a thicker texture.
  • Cooking tips: It will seem like you have a lot of sauce for the pasta – this is good! The sauce will cook down while in the oven, leaving just the right amount.
  • Storage: Store mac & cheese in an airtight container in the fridge for 3-4 days.
