BUTTERNUT MAC 'N' CHEESE

Steps:

• Squash:.
• Preheat oven to 400°F.
• Cut squash in half, lengthwise and rub cut side with olive oil.
• Place cut-side down on a baking sheet and roast for 60 - 75 minutes or until completely cooked and soft.
• Scoop out flesh while still warm and break apart with a spoon.
• Timing-wise, finish the squash roughly the same time the pasta and the sauce is cooked so that it's still warm.
• NOTE: You can change the ratio of squash to macaroni if you want it to be more or less squashy-I think this ratio is ideal because is comes out like mac n' cheese but there is still a good amount of squash hiding in there --.
• Cook macaroni in salted water.
• Let drain well. Timing-wise, finish the pasta and the sauce about the same time.
• Sauce:.
• In a saucepan, melt the butter on MEDIUM heat until shimmery.
• Stir in the onion as it's prepped, then the nutmeg and white pepper, cook until onions soften.
• Stir in the flour and mix well.
• A tablespoon at a time, add the milk, incorporating each tablespoon well before adding another. (If you add it all at once, or without working in each time, there's risk of ending up with a lumpy sauce).
• Stirring often, let the sauce come almost to the boiling point, it will thicken slightly.
• Add the cheese and let melt, adjusting temperature so that the sauce won't boil. (It's not a disaster if it does, since it's going into the casserole, but it'll look curdled).
• COMBINE.
• In a large bowl, break the squash apart, mashing it really, with a wooden spoon.
• Stir in the hot, drained pasta and combine well, distributing the squash throughout. Stir in the sauce and combine well.
• Transfer to a greased baking dish.
• If you like, sprinkle the top with pimento or paprika.
• If making ahead, let cool to room temperature, cover and refrigerate.
• BAKE.
• Return dish to room temperature.
• Bake at 350°F for 30 minutes until hot and bubbly throughout.
• To add color to the top, place under the broiler for 2 - 3 minutes, watching carefully so not to burn. When covered with foil, holds its temperature for a good 30 minutes.
