This is the best way to cook a whole bunch of bacon at once and have it come out perfect every time.
Line baking sheet with foil or parchment paper. For even crispier bacon, you can put a wire cooking rack on top of the foil and lay the bacon on that.
Place cookie sheet in UNHEATED oven and heat to 400 degrees.
Bake for 20-25 minutes to desired level of crispiness. Cooking time varies from oven to oven. Monitor the first batch to determine your ideal cooking time.
Cool and drain on paper towels.
Enjoy!
