Heat the oven to 200°C (400°F). Line a baking tray with foil and sit a wire rack on top for even crisping, or lay the bacon straight on the tray to keep more of the rendered fat.
Arrange the bacon in a single layer with no overlap. No oil needed, it cooks in its own fat.
Bake for 18 to 22 minutes, until deep golden and crisp. Thicker cuts take a little longer, so check from 18 minutes.
Rest the bacon for a minute to firm up. Pour the hot fat through a sieve into a jar, that is your dripping, perfect for frying eggs, searing steak and roasting.
Notes
Save every drop of the rendered fat. Beef and bacon dripping was the backbone of the British kitchen for centuries, before seed oils replaced it.
