Butternut squash mac and cheese is one of those fall dishes that feels both comforting and a little unexpected. I first tasted this variation at a family Thanksgiving and have been hooked ever since. While the squash does lighten the dish slightly compared with a traditional all-cheese sauce, the real appeal is the flavor: sweet, creamy squash balanced by sharp cheddar and fragrant herbs.
This version yields a smooth, velvety sauce that clings to the pasta and complements classic holiday flavors on your plate. The butternut squash becomes a subtle backdrop, while sharp cheddar provides the cheesy punch. I like to add fresh rosemary and thyme for warmth and complexity, and I always finish the bake with buttered panko and grated Parmesan for a crunchy, golden topping—don’t skip that final step if you want a contrast of textures.
No Roux Required
Unlike many mac and cheese recipes that start with a roux, this recipe relies on pureed butternut squash combined with milk and butter to create the sauce. The blended squash gives a naturally thick, creamy base that melts the cheese beautifully and shortens the prep. Because the squash is mild, be generous with salt and freshly ground black pepper to make the flavors sing.
Best Cheese for Mac and Cheese?
Because butternut squash has a gentle sweetness and subtle texture, it benefits from cheeses with clear flavor. I recommend a sharp cheddar as the backbone for flavor, and you can add a milder melting cheese—such as Fontina or mozzarella—for creaminess. Avoid overly salty or strongly flavored cheeses that will overpower the squash; the goal is balance, letting the squash and herbs complement the cheddar rather than compete with it.
Canned Versus Fresh Butternut Squash
Fresh butternut squash is my usual choice because it’s easy to prepare and you can cook it in the same pot you use for pasta to save time and dishes. A squash just over a pound is ideal for this recipe, or use pre-cut squash to speed up prep. You’ll only need a blender or food processor to turn it into a silky sauce.
If fresh squash isn’t available, a 15-ounce can of pureed butternut squash can substitute directly. Heat the canned puree with butter, garlic (or garlic powder if you prefer), chopped rosemary, and milk in a skillet until warm and smooth, then proceed with the rest of the recipe as written.

Butternut Squash Mac and Cheese Recipe
Ingredients
- 1 pound mezzi rigatoni, small shells, or elbows
- 1 pound fresh butternut squash, cubed (see note on canned)
- 8 ounces shredded sharp cheddar cheese
- 3/4 cup panko crumbs
- 1/2–1 cup whole or 2% milk (add more if needed)
- 1/3 cup shredded Parmesan cheese
- 4 tablespoons butter, divided
- 2 sprigs fresh thyme, leaves removed
- 1 sprig fresh rosemary, leaves removed
- 1/2 teaspoon garlic powder
- Salt and pepper, to taste
Instructions
- Preheat the oven to 400°F (200°C).
- Bring a large pot of generously salted water to a boil. Add the cubed butternut squash and cook until tender when pierced with a fork, about 10 minutes.
- While the squash cooks, mix the panko, 2 tablespoons melted butter, thyme leaves, and Parmesan in a small bowl. Set aside.
- Remove the cooked squash with a slotted spoon and transfer it to a blender. Add the pasta to the same boiling water and cook until al dente. Drain the pasta and set aside.
- Add the rosemary leaves, milk, garlic powder, and the remaining 2 tablespoons of melted butter to the blender with the squash. Blend until smooth and pourable; add more milk if the sauce is too thick.
- Pour the blended squash sauce into an oven-safe skillet over medium heat. Season with salt and pepper, then stir in the shredded cheddar until fully melted and the sauce is smooth.
- Add the cooked pasta to the skillet and stir to coat the noodles in the sauce. Evenly sprinkle the panko mixture on top and bake for 10 minutes. For a deeper golden crust, broil for 1–2 minutes, watching closely to avoid burning.
- Garnish with extra thyme if desired and serve warm.
Notes
Using canned squash: A 15-ounce can of pureed butternut squash can replace the fresh squash. Heat the canned puree in a skillet with melted butter, garlic (or garlic powder), finely chopped rosemary, and milk until smooth and warm before adding the cheese.
Texture tips: If you prefer a looser, creamier sauce, gradually add more milk until you reach the consistency you like. This recipe yields a creamy but somewhat dense sauce that clings to the pasta rather than running off.
Equipment note: A blender or food processor is needed to puree the squash into a silky sauce.
