Preheat oven to 400 degrees
Lay bacon strips on a parchment paper lined baking sheet, with spaces between strips. Wash brussels sprouts, trim ends and cut in half, pat dry. Place sprouts in between bacon strips, being careful not to put them on top of bacon. Drizzle with a little olive oil and season with salt and pepper.
Check after 15 minutes and remove bacon strips as they become done, continuing to check every 2 minutes, and removing bacon and sprouts to paper towels to drain after they are cooked. You want the bacon crisp and the Brussels sprouts slightly charred.
Add butternut squash to the same baking sheet and toss it around in the rendered bacon fat and season with salt and pepper. Return to oven for 5-7 minutes until noodles soften
Cut bacon into 2 inch pieces with scissors. Spray a baking dish and add noodles, bacon and Brussels sprouts. Drizzle with Alfredo, you can use a lot or a little, whatever your preference. Add some of the Parm and toss to combine. Add more cheese on top.
Cover and refrigerate at this point before baking if desired
Bake uncovered at 350 degrees until hot, about 30 minutes
