Butternut Squash Mac & Cheese
Ingredients
- 1 medium butternut squash about 2 pounds, peeled, seeded, and cut into 1-inch cubes
- 2 tablespoons olive oil
- 1 teaspoon salt divided
- ½ teaspoon black pepper divided
- 1 pound elbow macaroni or shells, cavatappi, or other short pasta
- 3 tablespoons butter
- 3 tablespoons all-purpose flour
- 2 cups whole milk can substitute 2% milk
- 1 cup vegetable or chicken broth
- 2 cups sharp cheddar cheese freshly grated (pre-shredded won’t melt as well)
- ½ cup Parmesan cheese freshly grated
- ¼ teaspoon ground nutmeg
- ¼ teaspoon cayenne pepper optional
- ½ cup panko breadcrumbs optional, for topping
Instructions
- Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper for easy cleanup.
- Toss the butternut squash cubes with olive oil, ½ teaspoon salt, and ¼ teaspoon black pepper until evenly coated. Spread in a single layer on the prepared baking sheet.
- Roast the squash for 25-30 minutes, stirring halfway through, until fork-tender and slightly caramelized at the edges.
- While the squash roasts, bring a large pot of salted water to a boil and cook the pasta according to package directions until al dente. Drain and set aside.
- Transfer the roasted squash to a blender or food processor and add the broth. Purée until completely smooth, adding more broth if needed to achieve a velvety texture.
- In the same pot used for pasta, melt butter over medium heat. Add flour and whisk constantly for 1-2 minutes to create a roux (it should smell slightly nutty but not brown).
- Slowly pour in the milk while whisking continuously to prevent lumps. Cook for 3-4 minutes until the mixture thickens enough to coat the back of a spoon.
- Stir in the butternut squash purée, remaining salt and pepper, nutmeg, and cayenne (if using) until well combined.
- Reduce heat to low and add the grated cheddar cheese in handfuls, stirring until completely melted before adding more. Then stir in ¼ cup of the Parmesan.
- Fold the cooked pasta into the cheese sauce until every piece is well coated. Taste and adjust seasonings if needed.
- For a baked version, transfer to a buttered 9×13 baking dish, top with remaining Parmesan and panko breadcrumbs, and bake at 350°F for 15-20 minutes until bubbly and golden on top.
Notes
- For extra flavor, add 1 tablespoon of fresh sage or thyme to the sauce.
- You can prepare the butternut squash purée up to 3 days in advance and refrigerate it until ready to use.
- This dish reheats beautifully – add a splash of milk when warming leftovers to maintain creaminess.
- For a time-saving hack, use pre-cut butternut squash from the grocery store.
- If you have an immersion blender, you can purée the squash directly in the pot instead of transferring to a blender.

Common Mistakes to Avoid
- Overcooking the pasta – Cook it just until al dente as it will continue cooking in the sauce.
- Using pre-shredded cheese – These contain anti-caking agents that prevent proper melting. Always grate your own for the creamiest sauce.
- Rushing the roux – Take your time with the flour and butter mixture; rushing can lead to a grainy sauce.
- Not thoroughly blending the squash – Ensure it’s completely smooth for the best texture.
- Adding cheese to a too-hot sauce – This can cause the cheese to seize and become stringy instead of melty. Always reduce heat before adding cheese.
Alternatives & Substitutions
- Dairy-free option: Use plant-based butter, unsweetened almond milk, and vegan cheese alternatives.
- Gluten-free version: Substitute gluten-free pasta and use rice flour for the roux.
- No butternut squash? Sweet potatoes or pumpkin purée work wonderfully as alternatives.
- Cheese variations: Try Gruyère, fontina, or gouda for different flavor profiles.
- Protein boost: Add cooked chicken, bacon bits, or sautéed mushrooms.
- Veggie additions: Fold in steamed broccoli florets, peas, or sautéed kale before baking.
