Preheat oven to 400F. Place bacon on a parchment lined baking sheet and bake for 15-20 minutes or until very crispy. Allow to drain on a paper towel and then crumble into small pieces. Set aside.
When done with the bacon, switch the oven to 350F.
In a medium/large saucepan heat the butter over medium heat. Once fully melted, add the flour, salt, pepper and garlic powder, and stir constantly to combine.
Slowly pour in the milk and cream, whisking constantly while you add. Allow to thicken, continuing to stir, until bubbly.
Add in the cheese, one cup at a time, stirring to melt before adding the second cup. Stir in the pumpkin and sage.
Remove from the heat and pour over the cooked pasta, stirring to combine. Stir in the bacon crumbles, reserving some for garnish if desired.
In a separate small bowl, combine panko, parmesan, and olive oil.
Pour the macaroni into a large baking dish, pressing down slightly with your spoon to make the top level.
Pour the panko mixture over the noodles, covering the entire top. Sprinkle with extra sage if desired.
Bake for 30 minutes, or until everything is hot and bubbly and the bread crumbs are golden and toasted.
Remove from the oven and allow to cool for 10 minutes before serving. Sprinkle with extra bacon!! Enjoy!
