  • Lock the lid in place and move the valve to the Sealing position. Pressure Cook/Manual on HIGH pressure for 4 minutes (half of the boiling time as instructed on the box).
  • When finished cooking perform a Quick Release of the pressure by slowly moving the valve to the venting position. Do it slowly to prevent any splattering.
  • Carefully open the lid and stir in half of the cheese and all but 9 pieces of pepperoni. Stir in olives or cooked bacon if using.
  • Sprinkle the remaining Mozzarella cheese on top and then place the remaining pepperoni on top of the cheese. Close the lid and let the cheese melt.

You can also freeze this casserole by transferring it to a foil pan before placing the Mozzarella and pepperoni on top. Once the casserole is in the foil, then place the remaining cheese and pepperoni on top. Cover and freeze.
To reheat the casserole, thaw it out the night before and heat in oven with the top loosely covered with foil at 350°F for 20-30 minutes.
