How to Make Butternut Squash Macaroni and Cheese

1. Cook the pasta in a large pot of salted water until it’s just al dente. Before you drain it, save about ⅓ cup of the pasta water, then set the pasta aside.
2. While the pasta is cooking, steam or boil the butternut squash until it’s really soft, about 10–12 minutes. Blend it until smooth using a blender or immersion blender.
3. Melt the butter in a saucepan over medium heat. Whisk in the flour and cook for 1–2 minutes, just until the mixture is lightly golden. This is your roux and will help thicken the sauce.
4. Slowly pour in the milk, whisking as you go so everything stays nice and smooth. Keep stirring until the sauce thickens, about 4–5 minutes.
5. Stir in the butternut squash puree, salt, black pepper, garlic powder, onion powder, and a pinch of nutmeg if you’re using it.
6. Turn the heat down to low and add the cheddar, mozzarella, and Parmesan. Stir until all that cheesy goodness is melted and the sauce is smooth.
7. If the sauce feels a little too thick, add a splash of that reserved pasta water until it reaches your favorite creamy consistency.
8. Add the cooked pasta and give everything a good stir until every noodle is coated in that creamy, cheesy sauce.
9. Serve it up warm and enjoy!

Variations & Substitutions

Pasta Options:
While traditional macaroni noodles are classic, feel free to use any type of pasta you love. Chickpea pasta or other gluten-free pasta works wonderfully and adds extra protein. Just cook according to package instructions until al dente for best results.

Cheese Swaps:
Sharp cheddar cheese is my go-to, but mixing in different shredded cheeses creates depth. Try gruyere, fontina, or extra Parmesan cheese. My hubs’ favorite addition is Swiss. While pre-shredded cheese is convenient, shredding your own cheese gives you better melt and flavor since it doesn’t contain anti-caking agents. The choice is yours based on your sodium level preferences too!

Milk Alternatives:
Whole milk creates the richest creamy texture, but you can substitute with almond milk, oat milk, or even a splash of milk mixed with Greek yogurt for tanginess. Just add a splash of milk at the end if your sauce gets too thick. NOTE – don’t use heavy cream. You can sub in about half if you want it thicker and richer – but the roux will seize up if you use all heavy cream when making this. You need the thinner consistency of milk for this.

Squash Substitutions:
No butternut? Try sweet potato or even pumpkin puree (hello, pumpkin mac!). A small squash versus a large squash just means adjusting quantities. You want about 2 cups of puree for a good base.

Add-Ins:
Crumbled bacon, sautéed mushrooms, or fresh thyme take this to the next level. For a crunchy topping, mix panko breadcrumbs with melted butter and sprinkle on top before baking. Fresh herbs like sage pair beautifully during this time of year.

Storage

Refrigerator Storage:
Store leftover butternut mac in an airtight container in the fridge for up to 4 days. The flavors actually develop and get even better the next day! When reheating, add a splash of milk to bring back that creamy sauce consistency since the cooked pasta absorbs moisture over time.

Freezer Storage:
I’m not a fan of thawed noodles; the texture is just never the same. I don’t recommend freezing this recipe.

Reheating Tips:
Reheat on medium-low heat on the stovetop, stirring frequently and adding milk as needed. You can also microwave individual portions, though the stovetop method on medium heat gives the best flavor and texture. If reheating the full recipe from the fridge, pop it in a preheated oven at 350°F covered with foil, then uncover for the last few minutes to crisp up the top.

Expert Tips

Roasting the Squash:
For maximum sweetness of the squash, roast your whole butternut (or halved large squash) cut-side down on a baking sheet until fork-tender. This concentrates the flavors better than steaming. Drizzle with olive oil and roast in a preheated oven at 400°F until golden brown and caramelized.

Cheese Melting:
Remove your large saucepan from heat before stirring in shredded cheeses. This prevents the cheese from becoming grainy. Stir in batches and let each addition melt before adding more. This is why shredding your own cheese matters since pre-shredded cheese doesn’t melt as smoothly.

Baking (Optional):
If you want that golden brown top, transfer everything to a large baking dish, top with extra cheese or panko breadcrumbs mixed with remaining butter, and bake until bubbly. This step isn’t required but makes it extra special!

FAQ’s

Can I use store-bought butternut squash puree?

Absolutely! Check the freezer or canned goods section at your grocery store. Just make sure it’s plain puree without added seasonings. This saves tons of time and still delivers a delicious mac and cheese.

Why is my sauce grainy?

This usually happens when cheese is added while the sauce is too hot or if you use pre-shredded cheese with anti-caking agents. Always remove from heat before adding cheese, and grate your own cheese when possible for the creamiest texture.

What should I serve with this?

This butternut mac pairs beautifully with roasted chicken, a simple green salad, or soft dinner rolls. It’s rich enough to stand alone as a vegetarian main or works perfectly on your Thanksgiving table alongside other sides.

What if I don’t have an immersion blender?

A food processor works perfectly! You can also use a potato masher for a chunkier texture, or even mash with a fork if your roasted butternut is soft enough. The goal is a smooth puree that blends seamlessly into your cheese sauce.
