    A pizza oven is about 450 C, so I’ll figure it out based on this graph of the temperature in the Earth by depth.

    0 to 500 C = 80 px
    6.25 C per pixel
    450/6.25 = 72 px
    
    0 to 100 km = 54 px
    1.85 km per pixel
    
    Line y coordinate at 72 px x coordinate = 9 px
    9*1.85 = ~17 km
    

    The deepest hole we’ve ever actually drilled is the Kola superdeep borehole, which is a bit over 12 km deep. This is a fair bit short of our ideal pizza oven temperature, but it did see temperatures of 180 C, which is certainly enough to cook a pizza.

      The geothermal gradient is different at different parts of the earth. You can probably bake a pizza at much shallower depths at the mid ocean ridge, near a volcano, or even at an active orogeny.

      In the area I live, this would mean you could be standing right next to the pizza cooking bore, and still be outside of the delivery range.
