Butternut squash mac and cheese takes the comfort of a classic favorite and adds a cozy autumn twist. The creamy sauce gets natural sweetness and velvety texture from butternut squash. With herby notes of thyme and a double cheese blend, this dish sneaks in veggies while feeling totally indulgent. It is my top way to add some fall feels to a busy weeknight—and nobody has ever noticed the extra veg.

I threw this together on an autumn night for a family dinner and we scraped the pan clean. What surprised me is how the goat cheese and squash together make it taste fancy with almost no work.

Ingredients

  • Butternut squash: frozen cubes make this hands-off or you can use fresh for stronger flavor look for squash with firm skin and deep orange flesh
  • Butter (unsalted): lets you control seasoning and helps the sauce gloss
  • Salt and black pepper: season every layer to keep flavors lively
  • Flour: helps make the creamy roux base use all purpose for best results
  • Whole milk: brings out creaminess avoid skim or watery milk for best sauce body
  • Cheddar cheese (sharp): melts into a classic tang and color always buy in a block and shred yourself for smoothest melt
  • Goat cheese (crumbled): adds a delicious tang and creamy lift look for fresh chevre not aged
  • Dried thyme: adds a savory fall note fresh thyme is even better if you have it
  • Garlic powder: boosts umami in the sauce choose a fine ground for even mixing
  • Cayenne powder: adds a whisper of warmth you can skip for kid friendly but I love the depth
  • Pasta (large shells or twirly shapes): hold the sauce best look for pasta with grooves or hollows
  • Pasta water (reserved): to adjust sauce consistency gives it perfect cling

Step-by-Step Instructions

Prep the Squash:
Combine frozen or peeled squash cubes with a splash of water in a skillet. Cover and steam on medium until squash is fork tender about seven minutes. Stir occasionally so nothing sticks. Uncover the pot then cook until water is gone and squash is soft and slightly caramelized. This helps concentrate flavor.
Build the Roux:
Add butter salt and pepper to the skillet. Stir until butter melts and coats the squash. Sprinkle flour over and stir constantly to form a paste. Cook until flour is absorbed and you smell a warm toasty aroma. This step gives the sauce its velvety finish.
Make the Cheese Sauce:
Slowly pour in the milk a bit at a time stirring smoothly so lumps do not form. Add garlic powder cayenne and thyme. Continue stirring and bring to a gentle simmer. Toss in both cheddar and goat cheese. Stir non-stop until everything melds together into a thick creamy sauce. Let cool slightly—this keeps it silky and prevents separation.
Boil the Pasta:
While sauce is cooling boil pasta in salted water three minutes shy of the timing on the box. Save some pasta water before draining. Return the cooked pasta to its pot.
Puree the Sauce:
Once the sauce is not piping hot transfer it gently to a blender. Puree until completely smooth and velvety. Do this in two batches if needed so it does not overflow.
Combine and Finish:
Pour the pureed cheese sauce over the cooked pasta in the pot. Stir with care so every shell is coated. Heat over low until the sauce thickens and clings perfectly. Add splashes of reserved pasta water to get your ideal creamy texture. Let the dish rest for five minutes so the sauce sets up and becomes luscious.

The tang that goat cheese brings is my absolute favorite part. My nephew once called this magical orange pasta after a fall picnic—it made me grin for days.

Storage Tips

Place leftovers in an airtight container and keep in the fridge for up to three days. When reheating add a splash of milk or water to loosen the sauce since it thickens as it chills. For longer keeping portion into ramekins and freeze for a quick thaw and heat meal on busy nights.

Ingredient Substitutions

You can use sweet potato instead of butternut squash which gives similar body and sweetness. If cheddar or goat cheese are not your thing swap in gruyere fontina or cream cheese for a milder creamy sauce. To make gluten free use chickpea or lentil pasta—just be careful with cooking time as they get soft quickly.

Serving Suggestions

Serve with a simple leafy green salad for a crisp contrast. Top with extra thyme and a scatter of toasted breadcrumbs if you want crunch. For a dinner party make this the centerpiece with sautéed mushrooms and a big bowl of roasted beets. Try serving it as a Thanksgiving side instead of traditional mac and cheese.

Cultural and Seasonal Touch

Butternut squash is a staple in fall and winter kitchens. Adding it to macaroni and cheese is a nod to classic southern vegetable bakes with a modern twist. My grandmother always baked squash casseroles for holidays so making this feels like a fresh version of those comfort foods.

Commonly Asked Questions

→ Can I use fresh instead of frozen butternut squash?

Large shells, cavatappi, or gemelli are excellent choices as they hold sauce beautifully and deliver satisfying texture.

→ How do I make the sauce extra creamy?

Ensure the roux is well blended and add milk gradually, stirring constantly. Pureeing the squash mixture yields a luxuriously smooth sauce.

→ Is goat cheese necessary?

Goat cheese adds tangy depth but you can use all cheddar if you prefer, or substitute with your favorite soft cheese.

→ Can I prepare this ahead of time?

Yes, store in an airtight container in the fridge for up to three days and gently reheat with a splash of milk to loosen the sauce.

What You'll Need

→ Sauce

01 500 g frozen butternut squash cubes (may substitute freshly peeled and cubed butternut squash)
02 60 ml water
03 2 tablespoons unsalted butter
04 0.5 teaspoon fine sea salt
05 0.25 teaspoon freshly ground black pepper
06 2 tablespoons plain flour
07 400 ml whole milk
08 0.5 teaspoon garlic powder
09 0.25 teaspoon cayenne pepper
10 1 teaspoon fresh thyme leaves
11 120 g sharp cheddar cheese, grated
12 80 g goat cheese, crumbled

→ Pasta

13 400 g large pasta shells or cavatappi
14 2 litres water, for boiling
15 1 tablespoon kosher salt, for pasta water

Step-by-Step Directions

Step 01

Fill a large pot with water, add 1 tablespoon salt, and bring to a rolling boil over high heat.

Step 02

In a large skillet, combine frozen butternut squash and 60 ml water over medium-high heat. Cover and cook, stirring occasionally, until squash is tender, 5 to 7 minutes. Uncover, increase heat to evaporate remaining liquid, stirring constantly for 2 to 3 minutes.

Step 03

Add butter, salt, and pepper to the skillet. Stir until butter melts. Sprinkle in flour and stir continuously until no dry flour remains and mixture is thickened, about 2-3 minutes.

Step 04

Slowly pour in milk, stirring constantly until incorporated. Add garlic powder, cayenne pepper, and thyme leaves. Bring sauce to a gentle simmer. Fold in cheddar and goat cheese; stir until completely melted and sauce is smooth. Remove skillet from heat and let sauce cool slightly.

Step 05

Add pasta to the boiling water and cook for about 3 minutes less than package instructions for al dente. Reserve 120 ml of pasta water, then drain pasta and return to pot.

Step 06

Transfer slightly cooled butternut squash cheese mixture to a blender. Blend until completely smooth and velvety. Work in batches if necessary.

Step 07

Return cooked pasta to low heat. Pour sauce over pasta, stirring until noodles are evenly coated. Cook gently until sauce just thickens, about 2 minutes. Remove from heat and allow to stand 5 minutes; sauce will continue to thicken as it cools. Stir in reserved pasta water as needed for desired consistency.

Step 08

Divide between serving bowls. Garnish with extra thyme if desired and serve immediately.

Helpful Notes

  1. Reserve some pasta cooking water to adjust sauce consistency if needed.
  2. For enhanced flavor, use roasted butternut squash instead of boiled, adding extra water if necessary during blending.
  3. Letting the combined pasta and sauce rest before serving ensures a creamy, cohesive dish.
