Start by preheating the oven to 400 degrees (convection bake).
Peel and dice the butternut squash (or buy precut) and add to a bowl.
Add oil and seasonings (salt, garlic, pepper and thyme).
Pour on a parchment lined baking sheet and set aside.
Line up bacon on parchment lined baking sheet.
Bake squash and bacon at the same time! Bacon will go about 20 minutes or so. I like it crispy, but just keep an eye on it. Squash will need 25-30 minutes. You want it golden brown.
While those are baking, boil water for pasta and cook according to package.
Chop spinach and shred parmesan and set aside.
Once the pasta is done, take 3/4 to 1 cup of pasta water out and set aside. You will need this for the sauce.
Drain pasta and add back to the pot.
Add in the butter, parmesan and half the pasta water and stir until combined!
Add in spinach, roasted butternut squash and a little salt.
Top with more fresh parmesan and the crispy bacon and enjoy!
