2cupscooked butternut squash flesh or 3 cups cubed, cooked squash
½teaspoondried mustard
2cupsgrated sharp cheddar cheese
2tablespoonsmelted unsalted butter
½cupbreadcrumbs
¼cupgrated parmesan
Instructions
Bring a large pot of salted water to a boil over high heat. Add the pasta and cook according to the package directions until al dente, 6 to 8 minutes. Drain the pasta and set aside.
Place cooked squash in a blender or food processor and puree, gradually adding in ½ cup of the milk, until the squash is smooth.
Melt the butter in a large saucepan over medium heat. Add the garlic and cook, stirring frequently, until fragrant, about 2-3 minutes. Whisk in the flour and cook until lightly browned, about 1 minute. Add the nutmeg and dried mustard and stir to blend in. Gradually whisk in the remaining 2 cups of milk and let the mixture come to a boil, continuing to whisk until the sauce has thickened. Turn the heat to low and whisk in butternut squash mixture. Remove from the heat and stir in the grated cheddar cheese a bit at a time until the cheese is melted. Add the cooked macaroni to the sauce and stir until the pasta is fully coated with the sauce.TIP: to up the vegetable content even more, add broccoli or cauliflower florets that have been pre-cooked, but are still el dente, to the macaroni and cheese sauce before baking.
Butter a 2-quart baking dish. Pour the macaroni and cheese sauce mixture into the baking dish.
Mix the breadcrumbs, grated parmesan, and the melted butter together. Sprinkle evenly overtop of the mac and cheese mixture.
Bake until bubbling and the breadcrumbs are lightly toasted, about 25-30 minutes. Remove from the oven and let rest for 5 minutes before serving.
