One-Pot Butternut Squash Mac

Featured in: Hearty Dinners

This dish combines tender butternut squash and pasta cooked together in a single pot. The squash is simmered until soft, then blended into a smooth, creamy sauce enriched with sharp cheddar and mozzarella cheeses. Aromatics like onion, garlic, Dijon mustard, and warm spices bring depth of flavor while the pasta cooks to a perfect al dente texture within the sauce. This method offers a cozy, vegetable-forward meal that's easy to prepare and satisfying to serve.

Recipe FAQs

Can I use a different type of squash?

Yes, butternut squash is preferred for its sweetness and creaminess, though kabocha or acorn squash can also work with slight flavor variations.

How do I prevent the pasta from sticking?

Stir frequently while simmering, and add additional milk as needed to maintain a smooth, saucy consistency around the pasta.

Is an immersion blender necessary for this dish?

An immersion blender blends the squash and aromatics directly in the pot, but you may use a countertop blender by carefully transferring the mixture in batches.

Can I add protein to this dish?

Yes, cooked diced chicken or white beans can be stirred in at the end to boost protein content without altering the creamy texture.

What cheese alternatives work well here?

Gruyère or Fontina can replace cheddar for a different flavor profile while maintaining creaminess.
