How Long to Reheat Deep Dish Pizza in Oven: A Comprehensive Guide to Pizza Perfection

Getting your deep dish pizza back to its former glory is all about finding the right oven temperature and timing. The thickness of your pizza, how hot it was when you put it away, and how crispy you want it to be—these all come into play. 

This guide will break down the factors that matter and give you step-by-step instructions for reheating your pizza to perfection!

Factors Affecting the Time Required for Reheating a Deep-dish Pizza

• Thickness of the Pizza
  Deep-dish pizzas are known for their substantial thickness, often measuring 1-2 inches or more. The thicker the pizza, the longer it will take for the heat to penetrate through to the center. A thicker pizza will require a longer reheating time compared to a thinner one, even at the same oven temperature.
• Initial Temperature of the Pizza
  If the pizza is taken straight from the refrigerator or freezer, it will require a longer time to reheat compared to a pizza that has been allowed to come to room temperature before reheating.
• Moisture Content
  Deep-dish pizzas tend to have a higher moisture content due to the generous amount of sauce and toppings. Maintaining the right moisture balance is crucial during reheating to prevent the crust from becoming soggy or drying out. Techniques like spritzing water or covering the pizza with foil can help retain moisture, potentially affecting the reheating time.
• Toppings and Fillings
  The type and quantity of toppings and fillings can also influence the reheating time. Pizzas with a higher concentration of toppings, such as meats or vegetables, may require longer reheating times to ensure that the toppings are heated through. Additionally, certain toppings like pepperoni or sausage may release more moisture during reheating, affecting the overall time required.
• Oven Type and Heating Mechanism
  Different oven types and heating mechanisms can impact the reheating time. For example, a convection oven, which circulates hot air, may reheat the pizza more quickly and evenly compared to a standard radiant oven. Similarly, a pizza oven designed specifically for high-temperature baking may require different reheating times compared to a conventional home oven.
• Preheating and Placement in the Oven
  Properly preheating the oven and the position of the pizza within the oven can also affect the reheating time. Placing the pizza on a preheated baking stone or pizza steel can help achieve a crispier crust more quickly, while positioning the pizza closer to the heat source may speed up the reheating process.

Remember, patience is key to perfectly reheating your deep dish pizza to preserve its flavor and texture. Keep a close eye on the oven to avoid overheating.

Step-by-Step Guide to Reheat a Deep Dish Pizza

Reheating a deep dish pizza correctly preserves its flavors and textures. Preparing the pizza properly before reheating is crucial to avoid a soggy crust or a dried-out topping.

Step 1: Preheat the Oven

First, you need to preheat your oven. Set the oven to the desired temperature. A moderate heat of about 350 degrees Fahrenheit (177 degrees Celsius) is ideal. Preheating ensures an even and efficient reheating process.

Step 2: Prepare the Deep Dish Pizza

If your deep dish pizza is coming out of the refrigerator, let it cool to room temperature for a few minutes. Cover the pizza with plastic wrap or place it in an airtight container to maintain its moisture.

Step 3: Moisture Boost

Before putting the pizza in the oven, spray a fine mist of water over the pizza to provide a moisture boost. A spray bottle is perfect for this step. This helps to keep the crust from drying out and becoming too tough.

Step 4: Cover the Pizza

Place the pizza slices on a baking sheet lined with parchment paper or aluminum foil for easy cleanup. Then cover the pizza loosely with a sheet of aluminum foil. This will prevent the toppings from burning and help retain the pizza's inherent moisture.

Step 5: Bake

Place the pizza in the preheated oven. The heating time can vary but typically bake for about 15-20 minutes. For thinner deep-dish pizzas, only 1-2 inches (2.5-5.1 cm) thick, baking for 15-17 minutes in the pizza oven is sufficient. For truly thick deep-dish pizzas or toppings that are harder to cook like mushrooms and tough vegetables like broccoli, cauliflower, squash, or fennel, you may wait for the full 20 minutes. As each slice of pizza's cheese begins to melt, and the dough takes on a slightly darker hue, you can tell that the pizza is fully cooked. It is also essential to check that the internal temperature reaches a safe level at 350 degrees Fahrenheit (177 degrees Celsius) and the crust becomes crispy.

Step 6: Serve and Enjoy

Once the pizza is heated through, and the crust is to your liking, remove the pizza from the oven. Let it cool for a 2-3 minutes, then serve and enjoy your delicious, perfectly reheated deep dish pizza.

Precautions for Reheating Deep Dish Pizza in the Oven

1. Avoid High Temperatures: Set the oven to 350°F (177°C). Higher temperatures may cause the crust to burn before the cheese and toppings are thoroughly heated.
2. Prevent Drying Out: Cover the pizza with aluminum foil. Wrap it loosely to keep the moisture in and prevent the crust and toppings from drying out.
3. Check for Uneven Heating: Rotate the pizza halfway through reheating. Ovens can have hot spots, and rotating the pizza ensures it heats evenly on all sides.
4. Monitor Closely: Check the pizza frequently, especially during the last 5-10 minutes. This helps you avoid overcooking or burning the pizza.
5. Handle with Care: Use oven mitts or heat-resistant gloves: When placing and removing the pizza from the oven to avoid burns. Be especially cautious of hot trays and racks.
6. Avoid Direct Rack Placement for Toppings: Place the pizza on a baking sheet or tray. This prevents toppings from falling off and making a mess in the oven. It also makes handling the pizza easier.
7. Ventilation: Ensure proper ventilation while using aluminum foil. Trapping too much moisture can lead to a soggy crust, so wrap it loosely and leave some gaps.
8. Prevent Soggy Crust: Remove the foil for the last 5 minutes of reheating. This allows the crust to crisp up while keeping the pizza moist and delicious.
9. Safety with Aluminum Foil: Ensure the aluminum foil does not touch the heating elements. This can cause a fire hazard. Keep the foil securely around the pizza but away from direct contact with the oven’s heating parts.
