Why I love this recipe.

Pasta with a cheese sauce is already perfect and often comes in the form of macaroni and cheese. This recipe is not meant to replace the macaroni and cheese we all know and love. Instead, this is a great variation when you want to use something seasonal in a new and exciting way. Butternut squash, and any winter squash, has become the start of fall cooking. The squash can be roasted, blended into soups, and sautéed so why not make it into a cheese sauce? Instead of hiding a vegetable, this recipe celebrates the addition of squash. The sweet and buttery-tasting squash is blended with some cheese for a sauce that is lighter than traditional cheese sauce but full of flavor. This may not take the place of all macaroni and cheese recipes, but it will definitely find a spot in the weekly lineup.

Everything you’ll need to make this recipe.

  • Butternut squash is a perfect fall-time addition and has a delicious flavor profile. This recipe uses one pound of squash, so look for a small to medium-sized one.
  • Garlic will add an immense depth of flavor that is needed to cut through the squash and cheese.
  • Chicken or vegetable stock is used to create a sauce with the squash. Use chicken or vegetable stock depending on personal preference for keeping it vegetarian.
  • Milk helps thin the sauce and create the right consistency while also offering a bit of richness.
  • Cheddar cheese will be the carrier of the cheese sauce. Use a good quality sharp cheddar for a more intense flavor or a milk cheddar for a more kid-friendly sauce.

Here’s how to make this recipe.

  1. Prepare the sauce. Over medium heat, melt butter in an oven-safe pan. Dice the onion and add to the butter along with the salt. Once the onion has begun to cook and turn translucent, add in the garlic and cook briefly for about 30 seconds to 1 minute. Then, add the chicken stock. Dice the squash into small cubes and add to the pan. Cover and let cook for 15-20 minutes.
  1. Cook the pasta. As the squash cooks, bring the water to a boil. Add kosher salt and the noodles and cook until al dente according to the pasta instructions.
  1. Blend the sauce. While the pasta cooks, take the sauce off the heat and add it into a blender with the milk. Blend until smooth, then add back to the pan. Add additional salt and black pepper. Add the shredded cheddar cheese and place on low heat until the cheese melts.
  1. Assemble and bake the dish. Drain the pasta and place it into the saucepan. Fold into the sauce. In a small bowl, combine melted butter, breadcrumbs, and Parmesan cheese. Place in a 375°F oven for 18 to 22 minutes until it bubbles throughout. Once baked, remove and serve warm.

These pro tips will make this recipe a success.

  • Preparing the squash is important. Make sure to remove the seeds and peel the squash. This dish requires the sauce to be well-blended and smooth. By removing the peel, the squash has a better consistency. When dicing the squash, be sure to cut it into small, uniform pieces. The smaller the pieces, the quicker it will cook.
  • Cooking the pasta al dente is vital for creating a good dish. Al dente means the pasta is not fully cooked yet. This is exactly what you want, as the noodles will finish baking in the sauce in the oven.
  • Vent the top of the canister when blending. Make sure the lid of the canister is on but has an opening for heat to escape while the squash blends. If it doesn’t have a place to escape, the heat can build, forcing the lid off the blender and causing a mess.

Frequently asked questions about this recipe.

Can a different type of squash be used?

Yes, any sweet winter squash can be used, but butternut is the easiest to peel. Kobocha, buttercup, and red kuri would be delicious but can be a bit more difficult to peel.

Can an immersion blender be used instead of a canister blender?

An immersion blender can be used but may not give the silky texture needed for this recipe. In a pinch, it will work, but for the best texture, a high-powered blender is best.

How long does this recipe keep after preparing?

The leftovers should be stored in an airtight container in the refrigerator. They will keep for 7 to 10 days.

Can this be made with vegetable stock in place of chicken stock?

Yes, the stock is easily substituted with vegetable in place of chicken.

What is a good cheese alternative to cheddar?

This is a great recipe with which to use any combination of cheeses. Gruyére, Monterey Jack, pepper jack, aged cheddar, and others would all be great options to use in place of the cheddar cheese. Stay away from dry cheeses, as they will not melt into the sauce correctly.

    Wondering about suggestions to add more protein (ie meat) to this recipe. Feeding 2 big guys who like their veggies and pasta but require meat with a meal too. Thinking sauté chicken cubes with the onions to give some colour then just carry on.
    Or serve chicken on the side!
