Bacon in the oven is hands-off and consistent. I like to use applewood smoked bacon that's cut very thick. Cooking time will vary depending on thickness, so watch carefully toward the end of cooking until you get a feel for how your oven and bacon work together. :)
Preheat oven to 400°F with a rack in the center. Line a rimmed half-sheet pan with aluminum foil. Arrange bacon in a single layer. (If you have to overlap the slices a little, it's okay -- they'll shrink.) Bake for 10 minutes, then flip slices and continue to bake until crisped to your liking, watching carefully toward the end. Cooking time will vary depending on thickness. Drain on paper towels and serve.
To make bacon in the oven for a bigger crowd, double the recipe. Use two baking sheets, one in the top third and one in the bottom third of the oven. Switch pans halfway through baking.
