I want all.the.pasta!

It’s that time of year when I start craving butternut squash everything and pasta. So why not combine the two? I mean, you probably already have a zillion recipes calling for butternut squash, so really what’s one more? Because this one is pretty darn tasty and was the first “Macaroni and cheese” recipe I made in my 20’s that was edible. True story. Thanks to Rachel Ray (and her body suits😂), I was able to make mac and cheese (or rigatoni and cheese) successfully.

Squash. Pasta. Cheese. Heaven.

Cheesy Roasted Butternut Squash Rigatoni ingredients

To Make This Cheesy Roasted Butternut Squash Rigatoni You Will Need:

  • dried rigatoni pasta
  • butter
  • shallot
  • garlic
  • fresh sage
  • unbleached all-purpose flour
  • low-sodium chicken broth
  • half & half
  • kosher salt
  • freshly ground black pepper
  • ground nutmeg
  • butternut squash puree
  • parmesan cheese
  • sharp cheddar (white or yellow)

I highly suggest that your ingredients be measured and by the stove top which will help speed it all along nicely.

butternut squash puree in glass bowl

Earlier this morning I roasted my butternut squash and pureed it.

dried rigatoni noodles in a bowl

Bring a large pot of water with a palmful of sea salt to a boil. I do this first before starting my sauce. It takes a bit to get a pot of water to boil, so it’s important to start this first. The sauce can wait on the pasta, not the other way around.

melted butter in saucepan

In a saucepan over medium to medium-low heat, I threw in 4 tablespoons of unsalted butter to melt.

shallots and garlic in melted butter

Once the butter has melted add in the minced shallots and garlic with a pinch of kosher salt. Stir and let it cook until softened, about 2-3 minutes.

sage added to sauteed shallots and garlic

Meanwhile I plucked ten beautiful, soft, fresh sage leaves from my garden and gave them a mince. It should be about 2 tablespoons.

flour added to herbs and garlic mixture

Once melted, I sprinkled in three tablespoons of flour.


Whisk it all together and let the flour cook for a minute.

add broth to roux

Once the flour has cooked, whisk in 1 cup chicken stock.

add half & half to broth and flour mixture

And 1-1/2 cups half & half.

season with black pepper and nutmeg

Season with a pinch of kosher salt, lots of freshly ground black pepper and 1/8 teaspoon nutmeg. I go easy on the salt because of the parmesan cheese and cheddar that I’ll be adding later.

thickened sauce

Now just cook the sauce on medium-low, whisking every so often, until it thickens. About 4-5 minutes.

add butternut squash and parmesan cheese to sauce

After the sauce has thickened, add in 1-1/2 cups of roasted butternut squash puree with 1 cup grated Parmesan cheese.

The squash is really what gives this pasta its color!

whisk cheese and squash into the sauce

Whisk to combine.

a little sharp cheddar into the sauce

Lastly, add in 1/4 cup of the extra sharp cheddar cheese. White or yellow cheddar, it doesn’t matter.

whisk until smooth

Keep whisking until everything is melty and smooth.

cooked rigatoni in a colander

Keep the sauce warm over low heat while you cook the noodles, following the directions on the box of course.

add cooked pasta to cheese sauce

When the noodles are al dente, add them into the pan with the cheese sauce.

toss to combine the pasta and cheese sauce

Toss well to combine.

top with cheese

Transfer the cheesy pasta to a lightly greased baking dish and sprinkle with the remaining 1 cup of cheddar. Preheat your broiler and slip it underneath for about 3 to 4 minutes. Watch carefully to avoid burning.


Oh yes. Crispy cheddar top, saucy center…

cheese strings!

All the cheese strings!

Serve spoonfuls into bowls and sprinkle with a little black pepper. Maybe even some chopped parsley if you’re feeling fancy.

I love the sage and shallot flavors going on. That along with the subtle sweetness of the squash and sharp cheese – SO, so good!

Enjoy! And if you give this recipe a try, let me know! Snap a photo and tag me on twitter or instagram!
