1mediumbutternut squash, halved, seeds and pulp discarded
12ouncesfettuccine pasta
6-8strips bacon, chopped
3clovesgarlic, finely minced
Pinchof ground sage
½cupmilk
½cuplow-sodium chicken broth
1cupshredded sharp cheddar cheese
1cupshredded white cheddar cheese
½cupfreshly grated Parmesan cheese
Instructions
Preheat the oven to 400 degrees. Place the butternut squash cut side down on a large, rimmed baking sheet. Add 1 1/2 cups water to the pan (it's easiest to add the water when the pan is already on the oven rack) and bake for about 40-45 minutes until the squash is tender. Remove from the oven and let cool in the pan for a bit (say, 10 minutes or so).
When cool enough to handle, scoop the flesh out of the squash halves and discard the skin. Puree the squash in a blender or food processor until smooth. You'll need at least 2 1/2 cups puree for this recipe.
In a large pot of boiling, salted water, cook the pasta according to the package directions. Reserve 1 cup of pasta water in a small bowl right before draining! Drain the pasta and set aside.
While the pasta is cooking, cook the bacon in a large, nonstick skillet until crisp. Transfer to a paper towel lined plate and drain all but 1 teaspoon grease from the skillet. Add the garlic and stirring constantly, cook briefly, about 30 seconds. Stir in 2 1/2 cups of the squash puree (reserve any remaining for another use) with the ground sage. Stir in the milk, broth, and 1/2 cup of the pasta water and bring the mixture to a low simmer.
One small handful at a time, add the cheddar cheeses, letting each addition melt before adding more. Add salt and pepper to taste (will depend on how salted your pasta water is; taste and add more if needed). Add the cooked pasta noodles and toss so the noodles are evenly coated with the sauce. Add any remaining pasta water if the sauce needs to be thinned out a bit.
Sprinkle with the Parmesan cheese and reserved bacon and serve immediately.
Notes
Noodles: for a true macaroni and cheese, sub out the fettuccine noodles for elbow macaroni. Squash: if you are working with already cubed butternut squash (like you can find in some produce sections), roast it on a sheet pan in the oven until soft and then puree. You want 2 1/2 cups butternut squash puree total. Make Ahead: the squash puree can be prepared a couple days ahead of time and refrigerated.
