Mushroom & Fennel Cast Iron Pizza

by | Updated: January 25th, 2023

This recipe gives the “personal pan pizza” a whole new meaning! Cancel your pizza delivery and instead take out your cast-iron skillet. If pizza dough sounds daunting, get a little help with the store-bought variety. Roast mushrooms and fennel in just 20 minutes, press the dough into your oiled skillet and top with sauce and prepared veggies. The piping hot cast iron skillet pizza will be all the more satisfying since it came directly from your oven.
