Butternut squash mac and cheese topped with golden crunchy panko bread crumbs and rich aromatic rosemary makes for a creamy, nutty, and healthy(ier) Thanksgiving side- or just a nice fall dish. One that makes you feel cozy and comfy as nights become cooler and forgotten warm winter coats are reluctantly remembered. Since I was a kid I have been making the macaroni and cheese recipe from Betty Crocker’s Cook Book for Boys and Girls. I have mentioned this tattered and loved cookbook before, whose recipes I still use in modified extent.
For the butternut squash mac and cheese I replaced the macaroni for roasted butternut squash, added a bit of depth with spices and rosemary, and crunch with the toasted panko bread crumbs. The butternut squash was perfectly tender and well-coated in the sharp cheddar cheese sauce. I like to use a shallow dish to maximize surface area for lots of crisp rosemary panko. Roasted butternut squash mac and cheese is fitting for a feast like Thanksgiving or if you’re feeling fancy, just a nice Tuesday night dinner.
Butternut Squash Mac and Cheese
- 2 lb butternut squash peeled, cored, and diced
- 2 tsp melted butter or ghee
- 1 tsp sea salt
- 1 tbsp butter
- 1 small diced white onion
- ¼ cup all-purpose flour
- ½ tsp dried ground mustard
- ¼ tsp cayenne pepper
- 2 cups milk (I used 2%)
- 12 ounces grated sharp cheddar cheese, 2 oz set aside for topping
- 1/8 tsp freshly grated nutmeg
- ¼ cup panko bread crumbs
- 1 sprig rosemary chopped
Preheat the oven to 400F. Peel the butternut squash, cut it in half, and core out the seeds. Dice the squash into nice little cubes for your butternut squash mac and cheese. Toss the diced butternut squash with the butter or ghee and sea salt. Roast the butternut squash for about 20 minutes or until almost done through. I opened the oven at 10 minutes and stirred the squash so it wouldn’t stick to the cast iron skillet. I like to use the skillet for aesthetics, but this would be easily done in a glass pyrex dish 9×13 would probably work best.
While the squash is roasting make the cheddar cheese sauce starting with the roux. I didn’t get to take great pictures of this step because my kitchen lighting is dismal. Melt the butter on medium to low heat and cook the onion until soft and tender. Add the flour and stir well, add the spices and allow the roux base to toast slightly for 2-3 minutes. Slowly add the milk, stirring constantly. Stir in the zebra white and yellow shredded cheddar and cook over low heat until sauce is thickened. Grate the nutmeg into the sauce and stir.
Add the butternut squash to the cheese sauce and gently stir. You want to keep the squash in neat little cubes. Add the butternut squash and cheese back into the cast iron skillet (or pyrex you roasted the squash in). I hate doing dishes so I try to use as few as possible! Mix the panko bread crumbs, rosemary, and the extra side of cheddar cheese. Top the butternut squash with the bread crumb mixture and bake for an extra 10 minutes until nice and golden brown on top. Butternut squash macaroni and cheese is a great Thanksgiving side dish.
