Preheat oven to 400 Degrees Fahrenheit and place oven rack in middle position.
Prepare Brussel sprouts by removing stem end and cutting in half lengthwise. Repeat process until all Brussel Sprouts are done.
Cut slices of bacon into 1/4 inch slices crosswise.
Place Brussel Sprouts on oiled sheet pan. If you like you can foil the pan but great the foil a bit with whatever oil you are using.
Place sprout face down to get the best caramelization and color.
Place chopped bacon on top of sprouts and drizzle with avocado oil and maple syrup.
Season with salt, pepper, and cayenne pepper (if using).
Toss together the spices, sprouts and bacon until well coated.
Once everything is coated well turn the sprouts face down and distribute the bacon pieces evenly so they get good contact with the pan and caramelize.
Place in oven for 20 to 30 minutes. Check after 20 to see if you are getting good color n the sprouts and that the bacon is looking good. If more cooking is needed let cook full 30 minutes and enjoy.
