This autumn-inspired mac and cheese transforms a classic comfort food with the addition of sweet roasted pumpkin and mellow roasted garlic.<br/>The combination creates a silky, flavorful sauce that coats every bite of pasta with cozy fall flavors while maintaining that cheesy goodness we all crave.
I first created this recipe when looking for ways to use the abundance of sugar pumpkins from our local farmers market. My family was skeptical about pumpkin in mac and cheese until they tasted it now it has become our most requested fall dinner tradition.
Ingredients
- Sugar pumpkin: freshly roasted pumpkin provides natural sweetness and a velvety texture that canned varieties simply cannot match
- Whole garlic head: roasting transforms harsh raw garlic into caramelized mellow goodness that infuses the entire dish
- Elbow macaroni: the classic shape catches pockets of sauce in each bite but any short pasta works well
- Sharp cheddar cheese: provides the quintessential mac and cheese flavor with just the right amount of tanginess
- Gruyère cheese: adds nutty complexity and superior melting qualities for the ultimate creamy texture
- Whole milk: creates a richer sauce than lower fat alternatives
- Butter and flour: forms the roux that thickens your sauce to the perfect consistency
- Nutmeg and smoked paprika: these warming spices complement both the pumpkin and cheese beautifully
- Panko breadcrumbs: optional but highly recommended for that irresistible crispy topping
Instructions
- Roast the pumpkin and garlic:
- Begin by preheating your oven to 400°F. Toss your peeled and cubed pumpkin with olive oil making sure each piece is well coated. Arrange in a single layer on a baking sheet. For the garlic slice just the top portion off to expose the cloves then drizzle with olive oil and wrap completely in foil. Place both on the same baking sheet and roast for a full 25 to 30 minutes. The pumpkin should be fork tender and slightly caramelized at the edges while the garlic will become soft and golden. This roasting process concentrates the flavors and adds a subtle sweetness that makes this dish special.
- Prepare the pasta:
- While your pumpkin roasts bring a large pot of water to a rolling boil. Add a generous amount of salt the water should taste like the sea. Cook your pasta for exactly 2 minutes less than the package directions indicate. This undercooking is crucial as the pasta will continue to cook when combined with the hot cheese sauce. Drain thoroughly but do not rinse the starchy exterior helps the sauce adhere better.
- Create the pumpkin garlic purée:
- Once your roasted items have cooled slightly transfer the pumpkin to a blender or food processor. Squeeze the roasted garlic cloves from their papery skins directly into the blender. Process until completely smooth with no visible lumps. This purée forms the flavor foundation of your sauce and should have a rich orange color and velvety consistency.
- Make the cheese sauce:
- In a heavy bottomed saucepan melt butter over medium heat. Sprinkle in the flour and whisk continuously for a full minute to cook out the raw flour taste. This creates a blonde roux which will thicken your sauce. Gradually add the milk about a half cup at a time whisking constantly to prevent lumps from forming. Continue cooking for 3 to 4 minutes until the sauce coats the back of a spoon. Stir in your pumpkin garlic purée until fully incorporated then add both cheeses a handful at a time allowing each addition to melt completely before adding more. Season with nutmeg smoked paprika salt and freshly ground pepper adjusting to taste.
- Combine and finish:
- Fold your cooked pasta into the cheese sauce ensuring each piece is thoroughly coated. For an extra special touch transfer to a baking dish and top with a mixture of panko breadcrumbs Parmesan cheese and melted butter. Broil for just 2 to 3 minutes watching carefully until the top becomes golden and crispy. This contrast of textures elevates the dish from good to memorable.

The roasted garlic is truly the secret weapon in this recipe. While it might seem like an extra step that could be skipped please trust me when I say it transforms the entire dish. I once made this recipe without roasting the garlic first and the difference was remarkable. The roasting process mellows the sharpness while bringing out a nutty sweetness that complements the pumpkin perfectly.
Make Ahead Magic
This mac and cheese can be prepared up to two days in advance. Simply assemble everything except the breadcrumb topping cover tightly and refrigerate. When ready to serve allow the dish to come to room temperature for about 30 minutes then bake at 350°F for 20 minutes. Add the breadcrumb topping and broil for the final few minutes. The flavors actually develop and improve with time making this an ideal dish for entertaining.
Seasonal Adaptations
While this recipe shines during pumpkin season it can be enjoyed year round with simple adaptations. In winter butternut squash makes an excellent substitute with a similar sweetness profile. Spring calls for lighter additions try stirring in fresh peas and herbs like thyme or basil just before serving. Summer versions can incorporate roasted cherry tomatoes or zucchini for bright seasonal flavor. The cheese sauce base remains your constant while the seasonal additions keep the dish fresh and exciting throughout the year.
Creative Serving Ideas
Transform this mac and cheese from a side dish to an impressive main course with thoughtful serving suggestions. Serve individual portions in hollowed out mini pumpkins for a show stopping presentation at fall gatherings. For a complete meal add a layer of sautéed garlicky kale or spinach before topping with breadcrumbs. The slight bitterness of the greens balances the richness perfectly. For a protein boost fold in crispy pancetta bits or top with butter seared scallops for an upscale dinner party option.
Cheese Variations
While sharp cheddar and Gruyère create the perfect balance of flavor and meltability feel free to experiment with different cheese combinations. Fontina offers exceptional meltability with a mild buttery taste. Smoked gouda adds depth and complexity that complements the roasted garlic beautifully. For a more pronounced fall flavor blue cheese can be added in small amounts approximately 1/4 cup crumbled into the sauce. Just remember to maintain a ratio of at least 75% good melting cheeses like cheddar Gruyère or fontina to ensure proper sauce consistency.

This creamy and flavorful mac and cheese is perfect for a cozy night in or a festive fall gathering. Enjoy the delicious taste of autumn in every bite.
