This recipe is now our tested, tried-and-true family favorite for an indulgent, yet secretly healthier, weeknight easy dinner. It delivers maximum comfort food vibes without the guilt. You absolutely need to make this!

💡 Expert Tips for the Best Results
- Roast the Squash: While you can boil or steam the squash, roasting brings out its natural sweetness and depth of flavor. Don’t skip this step!
- Use Freshly Grated Cheese: Pre-shredded cheese is coated in starches that prevent it from melting smoothly. Grate your cheese right before use for a perfectly smooth sauce.
- Low and Slow Roux: Cook your butter and flour mixture (the roux) slowly for 1-2 minutes. This removes the raw flour taste and ensures a flawless base.
- Nutmeg is Key: A pinch of freshly grated nutmeg elevates the cheddar flavor beautifully. It’s the secret ingredient of great cheese sauces.
Variations & Substitutions
This recipe is highly customizable! Here are some ways to switch it up based on your dietary needs or preference:
- Gluten-Free: Use your favorite gluten-free pasta (we love chickpea rotini!) and swap the all-purpose flour in the roux for GF flour or cornstarch.
- Dairy-Free/Vegan: Use plant-based butter, oat milk, and high-quality vegan cheddar shreds. The squash puree maintains the creamy texture, making this substitution surprisingly easy.
- Cheese Blends: Replace half the sharp cheddar with Gruyère, smoked Gouda, or Monterey Jack for a richer flavor profile.
- Add Protein: Stir in shredded rotisserie chicken, crumbled bacon, or Italian sausage.
Storage & Freezing
Mac and cheese is always best fresh, but it stores and reheats quite well if you follow these steps!
- Refrigeration: Store leftovers in an airtight container for up to 4 days. When reheating, add a splash of milk to loosen the sauce and restore creaminess.
- Freezing: We recommend freezing before baking if you are making a casserole dish. Assemble the dish, wrap tightly, and freeze for up to 2 months. Thaw overnight in the fridge before baking as directed, adding 10-15 minutes to the bake time.
Frequently Asked Questions
Do I have to roast the butternut squash?
While you can steam or boil it, roasting develops a caramel sweetness that greatly enhances the overall flavor of the sauce. It is highly recommended!
Can I use frozen squash?
Yes, you can! Thaw the frozen squash chunks and roast them briefly (or boil/steam) until tender. Just be sure to drain any excess water before pureeing.
What kind of pasta works best?
Any short pasta with ridges or curves works well to trap the sauce. Elbow macaroni is classic, but rigatoni, rotini, or cavatappi are also great choices.

Creamiest Mac and Cheese with Butternut Squash Puree
Ingredients
- 2 cups butternut squash, roasted and pureed (about 1 medium squash)
- 1 pound elbow macaroni or pasta of choice
- 4 tablespoons unsalted butter
- 1/4 cup all-purpose flour
- 3 cups whole milk, warmed
- 2 cups sharp cheddar cheese, freshly grated
- 1/2 cup grated Parmesan cheese
- 1/4 teaspoon nutmeg
- Salt and black pepper to taste
Instructions
- Step 1 Prepare Squash: Preheat oven to 400°F (200°C). Roast squash halves (cut side down) until tender (30-40 mins). Scoop out flesh and puree until smooth. Set aside 2 cups of puree.
- Step 2 Cook Pasta: Cook the macaroni according to package directions until al dente. Drain well and set aside.
- Step 3 Make Roux: Melt butter in a large saucepan over medium heat. Whisk in flour and cook for 1-2 minutes until golden, creating a roux.
- Step 4 Add Milk: Gradually whisk in the warm milk until smooth. Bring the mixture to a simmer, stirring constantly, until the sauce thickens (about 5-7 minutes).
- Step 5 Add Cheese & Puree: Remove the sauce from heat. Stir in cheddar cheese, Parmesan, nutmeg, salt, and pepper until the cheese is completely melted. Gently stir in the 2 cups of butternut squash puree until fully combined.
- Step 6 Combine and Serve: Add the cooked macaroni to the cheese sauce and toss gently until every noodle is coated. Serve immediately, or transfer to a baking dish, top with breadcrumbs, and bake for 15 minutes for a baked mac and cheese.
