Step 1To crisp your pancetta, lay the strips out on an oven rack and cook at 180 °C/ 355 °F (fan assisted), or 200 °C/ 400 °F (conventional), for 10 minutes until crispy. They will crisp further as they cool, so don’t overcook them.
Step 2Increase the heat to 190 °C/ 375 °F (fan assisted), or 210 °C/ 410 °F (conventional).
