Keto Spaghetti Squash Carbonara

Preheat the oven to 400 degrees F (200 degrees C). Line a baking sheet with parchment paper; place squash on top, cut-side down.

Bake in the preheated oven until skin is easily pierced with a fork, about 45 minutes.

While squash is cooking, fry bacon in a large skillet over medium-high heat until crisp, 5 to 10 minutes. Transfer to a paper towel-lined plate, reserving grease in skillet. Crumble bacon when cool enough to handle.
