Rochelle and I must be thinking along the same lines here :) just this last week I made a healthy version of mac and cheese as well using a baked butternut squash. It's so delicious, you can't stop eating it! Bon appetite!
Butternut Squash Mac and Cheese
6 T. butter
6 T. whole wheat flour
6 C. fat free milk
Make a roux with the butter and flour and then gradually add the milk until you have a thick white sauce.
1 package fat free cream cheese
1/2 C. parmesan cheese
1 C. cooked ground beef (optional)
1 butternut squash, baked and pureed*
Mix in the cheeses until melted, then add the other ingredients. Serve over noodles!
* I cut my butternut squash lengthwise and placed on a cookie sheet and baked in the oven at 375 for about 1 1/2 hours. You just need to make sure it's really cooked through to get the nice smooth texture you want for this recipe.
