Preheat the oven to 400°F and place a wire rack on top of a rimmed baking sheet and spray with nonstick spray and set aside. Slice the top off of the jalapeños and carefully remove the seeds inside.
Wrap each jalapeno with a strip of bacon. Place onto the prepared wire rack-lined baking sheet and bake for 10 minutes on the center rack. Turn over and bake for another 10 minutes.
