Yes, you can bake an undercooked deep dish pizza in the oven to finish cooking it. Here's how you can do it:
Preheat the oven: Preheat your conventional oven to around 375-400 degrees Fahrenheit (190-200 degrees Celsius). Adjust the temperature based on your oven's settings and the specific instructions for your deep dish pizza.
Check the pizza: Take a look at the undercooked deep dish pizza. If the crust is already browned and only the toppings need further cooking, you can proceed to step 3. However, if the crust is still pale or uncooked, you may need to cover the top with aluminum foil to prevent over-browning while the crust cooks through.
Transfer to oven-safe dish: If the pizza was initially baked in a non-oven-safe pan or skillet, transfer it to an oven-safe dish. A pizza stone or a baking sheet lined with parchment paper would work well.
Continue baking: Place the pizza in the preheated oven and bake until the crust is fully cooked, and the toppings are heated through and appropriately melted and browned. The cooking time will vary based on the thickness of the pizza and the specific toppings used. It typically takes around 10-15 minutes, but keep a close eye on it to avoid overcooking.
Check for doneness: To check if the deep dish pizza is fully cooked, insert a toothpick or a knife into the center of the pizza through the crust. If it comes out clean and the crust looks golden-brown, it's likely done.
Rest before serving: Allow the pizza to rest for a few minutes after taking it out of the oven. This helps to set the toppings and make it easier to slice and serve.
Keep in mind that while it's possible to finish cooking an undercooked deep dish pizza in the oven, the final result may not be the same as if it had been cooked correctly from the start. The texture and taste could be slightly different, but it should still be safe to eat as long as it reaches a safe internal temperature (above 165°F/74°C) during the baking process.
