Step 1First, prepare the crispy bacon. Preheat the oven to 190 °C/ 375 °F (fan assisted), or 210 °C/ 410 °F (conventional). Line a baking sheet with parchment paper. Lay the bacon strips out flat on the paper, leaving space so they don’t overlap. Place the tray in the oven and cook for about 10 to 15 minutes until the bacon is browned.
