Preheat the oven to 400° F.
Use a sharp knife or food processor to thinly shave the brussel sprouts.
Toss everything (except the lemon juice) together and spread into an even layer on a large sheet pan. Add another drizzle of olive oil.
Bake for 35-40 minutes, stirring every 15 minutes or so, until the bacon and brussel sprouts are crispy.
Squeeze over the lemon juice and serve.
