Key Ingredients & Smart Swaps
- Butternut Squash: Buy it pre-cubed in the produce section to save 15 minutes of peeling and chopping!
- Sharp Cheddar Cheese: Always grate it yourself from a block. Pre-shredded cheese contains anti-caking agents that make sauces grainy.
- Pasta Shells: The little cups perfectly catch and hold the thick cheese sauce. Macaroni or cavatappi work great too.
- Heavy Cream & Broth: Thins out the squash puree into a pourable, rich sauce.
- Fresh Sage: A classic pairing with butternut squash. Frying the leaves in a little butter for 30 seconds makes an incredible crispy garnish.
Step-by-Step Cooking Walkthrough
1. Roast the Squash: Toss cubed butternut squash with olive oil and salt. Roast at 400°F (200°C) for 25 minutes until tender and caramelized on the edges.
2. Boil the Pasta: Cook your pasta shells in heavily salted boiling water until al dente. Drain and set aside.
3. Blend the Sauce Base: Transfer the roasted squash to a blender along with the heavy cream, vegetable broth, and minced garlic. Blend until completely smooth.
4. Melt the Cheese: Pour the squash mixture into a large pot over medium-low heat. Stir in the butter, grated cheddar, and parmesan cheese until melted and velvety.
5. Combine & Garnish: Fold the cooked pasta into the cheese sauce until every shell is coated. Top with fresh sage leaves crisped in butter and serve immediately!
3 Chef Secrets for Perfect Results
1. Salt Your Pasta Water: It should taste like the sea. This is your only chance to season the actual pasta itself from the inside out.
2. Roast, Don’t Boil: Roasting the butternut squash evaporates excess water and concentrates the natural sugars, leading to a much deeper flavor than boiling it.
3. Never Boil Cheese: When melting the cheese into the squash puree, ensure the sauce never comes to a rolling boil, or the proteins will seize and separate.
What to Serve With Butternut Squash Mac and Cheese
- Proteins: Serve as a decadent side dish alongside roasted chicken, pork chops, or our Garlic Butter Steak Bites.
- Greens: A bright, acidic arugula salad with lemon vinaigrette cuts through the richness beautifully.
- Roasted Vegetables: Charred broccoli or Brussels sprouts.
Storage, Freezing & Reheating Instructions
- Refrigeration: Store leftovers in an airtight container for up to 4 days.
- Gentle Reheating: Reheat in a saucepan over medium-low heat. Add a splash of milk or broth to loosen the sauce, as it will thicken significantly in the fridge.
- Freezing Guidelines: Freeze in an airtight container for up to 2 months. Thaw overnight in the fridge before reheating gently.
