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.
0to500 C =80 px
6.25 C per pixel
450/6.25=72 px
0to100 km =54 px
1.85 km per pixel
Line y coordinate at72 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.

Keep digging. You can’t rush a good pizza.
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.
