First, check that your Ooni Pro is ready to be fired up: Remove the chimney cap, open the chimney and ceiling vents and put on the door you want to use.
Remove the hatch and place a layer of charcoal or a small stack of wood in the wood and charcoal burner. Our favourite methods for lighting wood and charcoal are a gas blowtorch or Ooni Firestarters.
Once you have a nice burn going, add more fuel. Replace the hatch and leave your Ooni Pro to preheat for 20-30 minutes. Keep an eye on the fire and add more fuel as needed. Remember, less is more and adding too much at once can smother the flame.
You can use charcoal and wood on their own, but we love combining the two for an even heat and unbeatable flavour. You can see how Kristian does it here:
