Let’s Make This Life-Changing Butternut Squash Mac and Cheese!

Step 1: Get Your Oven Ready Preheat to 400°F and grab a 9×13 baking dish. Get all your ingredients out because once you start, this butternut squash mac and cheese comes together pretty quickly.

Step 2: Cook That Pasta Bring a big pot of salted water to a boil (and I mean SALTED – it should taste like the ocean). Cook your rotini for 8 minutes until it’s al dente. Don’t overcook it because it’ll keep cooking in the oven.

Step 3: Make the Magic Roux While the pasta’s cooking, melt butter in a large saucepan over medium heat. Whisk in flour, garlic powder, onion powder, dry mustard, and nutmeg. Cook for exactly 1 minute, whisking constantly – this gets rid of that raw flour taste.

Step 4: Build That Cheese Sauce Slowly whisk in the milk, adding it gradually so you don’t get lumps (nobody wants lumpy mac and cheese). Cook until it bubbles and thickens to about heavy cream consistency – this takes about 5 minutes.

Step 5: Add the Good Stuff Remove from heat and stir in your mashed butternut squash and both cheeses. Keep stirring until everything melts into this gorgeous, creamy sauce. Season with salt and pepper to taste.

Step 6: Bring It All Together Mix your cooked pasta with the cheese sauce until every piece is coated. Transfer to your baking dish and sprinkle those breadcrumbs on top for that perfect golden crust.

Step 7: Bake to Perfection Pop it in the oven for 20 minutes until the top is golden and the sauce is bubbling around the edges. Let it rest for 5 minutes before diving in – this butternut squash mac and cheese is molten hot when it first comes out!

Frequently Asked Questions

Can I use frozen butternut squash for this mac and cheese?

Absolutely! Frozen butternut squash works perfectly in this recipe. Additionally, it saves significant prep time while maintaining excellent flavor.
Thaw the squash completely and drain excess moisture before mashing. Furthermore, frozen squash often provides more consistent results than fresh.

How do I prevent the cheese sauce from becoming lumpy?

Always remove the roux from heat before adding cheese. Additionally, add cheese gradually while whisking continuously.
Furthermore, use freshly grated cheese rather than pre-shredded varieties. The anti-caking agents in pre-shredded cheese can cause lumps.

Can I make this butternut squash mac and cheese ahead of time?

Yes! Assemble the entire casserole up to 24 hours in advance. Additionally, cover tightly and refrigerate until ready to bake.
Add the breadcrumb topping just before baking. Furthermore, you may need to extend the baking time by 5-10 minutes if starting from cold.

What’s the best way to reheat leftover butternut squash mac and cheese?

Reheat individual portions in the microwave with a splash of milk. Additionally, cover to prevent drying out during reheating.
For larger portions, reheat in a 350°F oven covered with foil. Furthermore, stir halfway through the reheating process for even warming.
