Start heating oven to 400°F. Place the bacon strips close together on the baking sheet and put the baking sheet immediately into the oven even before the oven is completely heated.
Bake 20 minutes, turning the slices over after about 12 minutes, if desired. Remove from the pan with a pair of tongs and place on paper towels on a platter.
Save the grease to use in other ways … like cooking eggs, sauteeing vegetables, or making tortillas.
