We made a lot of pizzas while testing outdoor pizza ovens but we made even more mistakes. Outdoor pizza ovens are relatively niche compared to grills and there's even more of a learning curve to master skills. To save you some time and hassle, I've compiled a list of what went wrong while testing pizza ovens along with lessons learned. The vast majority of outdoor pizza ovens have foldable legs that only raise the oven a couple inches off the ground. Cooking in an outdoor pizza oven is a hobby because of the hands-on method and endless topping combos.
