Butternut Squash Mac and Cheese

This creamy butternut squash mac and cheese is comfort food at its coziest. Roasted squash adds a gentle sweetness and smooth texture that transforms classic macaroni and cheese into something nourishing and just a little bit special. I love making this dish for weeknight dinners when I want a hearty meal that is still packed with goodness.

My kids ask for this every time the weather gets cold. I first made it as a holiday side and it quickly became the star of the meal.

Ingredients

• Elbow macaroni or small pasta shells: these shapes hold onto the creamy sauce and give a satisfying bite. Look for bronze cut pasta for best texture.
• Butternut squash, peeled and diced: brings creamy richness and natural sweetness. Choose squash with a firm skin and deep orange color.
• Small onion, diced: for a sweet savory backbone. Yellow onions work best but shallots add complexity.
• Garlic, minced: a gentle punch of flavor. Fresh cloves always beat pre-minced for taste.
• Unsalted butter: balances richness and keeps the sauce smooth.
• Whole milk: adds creaminess and helps blend the squash. Whole milk is ideal but two percent can work if needed.
• Sharp cheddar cheese, shredded: melts smoothly and gives classic tang. Always grate from a block for best texture.
• Gruyère cheese, shredded: brings nutty depth. Use high quality cheese for optimal melt.
• Parmesan cheese, grated: for that salty umami kick. Freshly grated is key.
• Sour cream: lifts the sauce with a slight tang and extra body.
• Salt: start with half a teaspoon and adjust to taste. Sea salt rounds out flavors.
• Ground black pepper: gives a hint of spice and heat.
• Ground nutmeg: brings warmth and complexity. Just a pinch goes a long way.
• Mustard powder (optional): highlights the cheese flavor. Use fresh powder for brightness.
• Panko breadcrumbs (optional topping): adds crunch. Japanese style is particularly crisp.
• Melted butter: for mixing with breadcrumbs to help brown and crisp the topping.

Instructions

Prep the Squash and Oven:

Preheat your oven to two hundred degrees Celsius or four hundred degrees Fahrenheit. Line a baking sheet with parchment paper so the squash will not stick and cleanup is easier.

Roast the Squash:

Toss peeled and diced butternut squash with a splash of olive oil salt and black pepper. Arrange the squash pieces in a single layer for even roasting. Bake for twenty to twenty five minutes until fork tender and caramelized on the edges. This brings out depth and sweetness.

Boil the Pasta:

Fill a large pot with water and season generously with salt. Bring to a rolling boil then add the pasta. Cook until al dente according to package instructions. Do not overcook as pasta will absorb some sauce later. Drain well and set aside.

Sauté Onion and Garlic:

Melt unsalted butter in a large heavy saucepan over medium heat. Add diced onion and sauté for three or four minutes until translucent and soft but not browned. Sprinkle in the garlic and cook for one more minute. This builds a flavorful base for your sauce.

Combine and Puree:

Place roasted squash pieces into the saucepan with onion and garlic. Pour in whole milk to help blend everything together. Use an immersion blender right in the pan or transfer everything to a blender in batches. Blend until perfectly smooth and creamy for a luscious sauce texture.

Add Cheeses and Seasonings:

Return the smooth sauce to your saucepan if you used a blender. Immediately stir in all shredded cheeses and grated Parmesan. Add sour cream nutmeg and mustard powder if using. The heat will melt everything into a velvety sauce. Taste and adjust salt and pepper to your liking.

Mix with Pasta:

Add cooked pasta directly to the cheese sauce and gently stir with a spatula or spoon until every shape is thoroughly coated and glossy.

Finish with Crunchy Topping:

If you like a crunchy topping move oven rack to broiler position and preheat broiler. Mix panko breadcrumbs with melted butter and scatter over the top of mac and cheese in an oven-safe dish. Broil just two or three minutes until golden browned and smelling toasty. Watch closely so it does not burn.

Serve Immediately:

Spoon hot mac and cheese onto plates. Garnish with an extra sprinkle of Parmesan cheese or fresh herbs like chives or parsley for color and flavor.

Save

My favorite part is always the combination of sharp cheddar and Gruyère that gives this dish both comfort and elegance. Making this with my little ones is a family tradition and we love all pitching in to stir the bubbling sauce together.

Storage Tips

This mac and cheese keeps beautifully in the fridge for three days in a tightly covered container. For best texture add a splash of milk before reheating to loosen the sauce. Leftovers can be microwaved in short bursts or gently baked in the oven.

Ingredient Substitutions

You can swap Gruyère with mozzarella for a milder flavor or choose Monterey Jack for extra creaminess. Gluten-free pasta and gluten-free breadcrumbs make this accessible for those with sensitivities. For a dairy-free option substitute with plant based milk vegan cheese and coconut yogurt for the sour cream.

Serving Suggestions

Serve alongside a crisp green salad dressed with lemon vinaigrette for balance. Steamed broccoli or sautéed peas make a lovely companion and add color. This dish pairs beautifully with dry Chardonnay or a tart apple cider for grown ups.

Cultural and Historical Notes

Mac and cheese is American comfort food but the butternut squash twist brings in a New England autumn influence. Roasting squash dates back centuries for making soups and stews hearty and nourishing while cheddar cheese has historic roots in farmhouse kitchens.

This recipe brings extra warmth to any dinner table and is sure to be a new family favorite. Leftovers are just as delicious the next day.
