I use a 10"x15" jelly roll pan or the bottom of a broiling pan. I buy parchment paper for baking in rolls in bulk online, but you can get it at the supermarket or any cooking supply store.
I bake 3 pounds of bacon at a time ( not all at once - in batches) and freeze it in individual servings.
Preheat oven to 400 degrees F.
Line a 10"x15" jelly roll pan with parchment paper for cooking/baking.
Place 8 slices of bacon across the short side of the jelly roll pan flat on top of the parchment paper.
When the oven comes up to temperature, place the pan with the bacon on the middle shelf of the oven and bake for 15 minutes. When the 15 minutes is up, check the bacon.
Sometimes, I like to have it a little limp (for things like potato soup) , but if you like it crispy, add more time, rechecking it every 1-2 minutes for desired doneness. ( crisp is usually about 20 minutes)
Remove finished bacon to paper towels or brown paper and blot excess grease off bacon with paper towels.
Drain bacon grease into a can.
Repeat process until entire 3-pounds of bacon is cooked.
Freeze in portion sized bags.
