January comfort food at its finest: velvety butternut squash folded into sharp cheddar and Gruyère, blanketing perfectly al dente elbow macaroni. It’s the hug-in-a-bowl we all need after the holiday whirlwind.
Every January, after the sparkle of the holidays fades and the fridge is finally clear of cookie plates and champagne bottles, I crave something nourishing but still indulgent—something that tastes like coziness without the post-feast slump. That’s how this butternut squash mac and cheese was born. I first tested it during a snow-day marathon baking session; the squash was sitting on my counter begging to be used, and the kids were clamoring for “regular mac and cheese.” One blender whir later, the vibrant orange purée disappeared seamlessly into the cheesiest sauce we’d ever tasted. They devoured seconds. I did a quiet mom-victory dance.
The beauty of this dish is that it feels decadent, yet it sneaks in a full cup of vegetables per serving—so you can start the year on a feel-good note without sacrificing flavor. Make it for a weeknight family dinner, serve it in mini skillets for a casual winter gathering, or pack it into thermoses for ski-day lunches. However you spoon it up, it’s guaranteed to brighten the coldest, darkest month of the year.

Ingredients You'll Need
Quality ingredients make or break mac and cheese. Here’s what to look for:
Butternut Squash: Choose one that feels heavy for its size with matte, unblemished skin. If you’re in a rush, grab two 10-oz packages of pre-peeled squash cubes. Frozen squash works too—just thaw and pat dry.
Elbow Macaroni: Classic, yes, but shells or cavatappi trap extra sauce. Whole-wheat elbows add nuttiness; gluten-free brown-rice pasta works without becoming gummy.
Sharp Cheddar: Buy a block and shred yourself. Pre-shredded cellulose coatings inhibit smooth melting. White or yellow both taste great.
Gruyère: A small wedge lends incredible nutty aroma. Can’t find it? Swap in fontina or mild provolone.
Whole Milk & a Splash of Cream: The squash already lightens things, so you need just enough dairy for silkiness. Oat milk works for dairy-free—opt for the “full-fat” version.
Nutmeg & Sage: January squash’s best friends. A whisper of nutmeg amplifies sweetness; fresh sage sautéed in brown butter is heavenly if you want to gild the lily.
Dijon Mustard: My secret weapon—1 tsp brightens all that cheesy richness.
How to Make Creamy Butternut Squash Mac and Cheese for January
Roast (or Boil) the Squash
Preheat oven to 425 °F if roasting. Toss 4 cups cubed squash with 1 Tbsp olive oil, salt, and pepper on a parchment-lined sheet. Roast 20 min until caramelized edges appear. OR skip the oven: simmer squash in the same pot you’ll later cook pasta in, 10 min until fork-tender. Drain and set aside.
Cook the Pasta
Bring a large pot of well-salted water to boil (1 Tbsp salt per quart). Add 12 oz elbows and cook 1 minute shy of package directions. Reserve 1 cup starchy pasta water, then drain. Do not rinse—the residual starch helps sauce cling.
Purée the Veg
Blend warm squash with 1 cup milk, ¼ cup cream, 1 tsp Dijon, pinch nutmeg, and ½ tsp salt until velvety. A high-speed blender aerates beautifully; an immersion blender works right in the pot.
Build the Roux
Return pot to medium heat. Melt 3 Tbsp butter, add 2 Tbsp flour, whisk 60 sec until nutty aroma rises but color stays pale. Gradually whisk in squash mixture until thick enough to coat the back of a spoon.
Melt in the Cheese
Reduce heat to low. Stir in 1½ cups shredded sharp cheddar and 1 cup shredded Gruyère a handful at a time until glossy. If sauce tightens, splash in reserved pasta water.
Marry Pasta & Sauce
Fold drained elbows into the pot until every noodle is luxuriously coated. Taste and adjust salt and pepper.
Optional Crunch Topping
For bakery-style crunch, melt 1 Tbsp butter in a skillet, add ¾ cup panko + pinch smoked paprika, toast 2 min. Sprinkle over mac.
Serve or Bake
Serve stovetop-creamy, or transfer to a buttered 9-inch baking dish, top with extra cheese and panko, and bake 10 min at 400 °F for bubbly edges.
Expert Tips
Low Heat = Smooth Sauce
High heat splits cheese, creating grainy texture. Patience pays.
Reserved Pasta Water
Its starch loosens sauce without watering down flavor.
Frozen Squash Shortcut
Skip peeling—use frozen cubes. Thaw, pat dry, then purée.
Double Batch Rule
Cheese sauce freezes well; freeze flat in zip bags for quick thaw meals.
Color Pop
Add roasted red-pepper strips for sweet contrast and photo-ready hue.
Make-Ahead Bake
Assemble the night before; refrigerate. Add 10 min to covered bake time.
Variations to Try
- Spicy Kale: Stir in 2 cups chopped kale and ½ tsp red-pepper flakes with the roux; finish with pepper-jack cheese.
- Smoky Bacon: Cook 4 strips bacon until crisp; use 2 Tbsp rendered fat instead of butter for roux. Top with crumbled bacon.
- Vegan Remix: Swap butter for olive oil, flour for rice flour, milk for oat milk, and cheese for 1 cup nutritional yeast + ½ tsp white miso.
- Lobster Luxe: Fold in 8 oz cooked lobster meat and 1 tsp lemon zest before baking—perfect for New Year’s Eve leftovers.
- Maple-Glazed Squash: Drizzle squash with 1 Tbsp maple syrup before roasting for sweet-savory depth.
Storage Tips
Refrigerate: Cool completely, transfer to airtight container, and refrigerate up to 4 days. Reheat gently with a splash of milk while stirring.
Freeze: Portion into freezer-safe containers, press plastic wrap onto surface to prevent ice crystals, freeze up to 3 months. Thaw overnight in fridge, then reheat stovetop or covered at 350 °F until center reaches 165 °F.
Make-Ahead Casserole: Assemble through Step 6, cover tightly with foil, refrigerate up to 24 hrs. Add 10 min to covered bake time; uncover for final 5 min to brown top.
