How to Build a Cardboard Pizza Oven

How to Build a Cardboard Pizza Oven

Building your own cardboard pizza oven is a fun DIY project that allows you to make delicious homemade pizzas. With just a few simple materials, you can construct an oven that will heat up to over 700°F and cook authentic brick oven-style pizzas.

Gather the Necessary Materials

To build the cardboard pizza oven, you will need:

  • Cardboard boxes – Look for large, sturdy boxes. Appliance boxes or moving boxes work well. You need about 6-8 boxes.

  • Aluminum foil – Get heavy duty foil to withstand high heat. You’ll need about 50 square feet.

  • Scissors or box cutter – To cut and shape the cardboard pieces.

  • Glue – Go for a strong glue like wood glue or liquid nails.

  • Duct tape – Helpful for assembling and sealing the oven.

  • Pizza stone – Absorbs moisture for crispy crusts. Get a round one that fits your oven.

  • Parchment paper – Place this on the pizza stone to prevent sticking.


  • Small bubble level – To ensure oven sits level
  • Paint or varnish – For finishing touches

Construct the Oven Frame

The first step is building the main body of the oven:

  1. Cut the cardboard into panels using scissors or a box cutter. Make the panels about 12-18 inches wide.

  2. Assemble into a dome shape. Glue the panels together in an arched dome formation. Think igloo shape. Use plenty of glue for strong bonds.

  3. Create an oven entrance. Cut out a large opening (8×12 inches) in the front for the pizza entrance.

  4. Build up the entrance. Use cardboard pieces to create a raised surface around the opening. This allows you to slide pizzas in and out easily.

  5. Add structural support. Use extra cardboard panels glued inside to reinforce the shape. Aim for 2-3 layers total.

  6. Seal all seams thoroughly with glue and duct tape. This prevents smoke and heat escaping.

Insulate and Finish the Oven

Now insulate and finish the oven:

  • Wrap oven in foil. Cover every surface with heavy duty aluminum foil. Reflects heat back into the oven.

  • Add insulation. Surround oven with crumpled newspaper or fiberglass insulation. This traps heat inside for maximum temperatures.

  • Install pizza stone. Place round pizza stone in center of oven floor to absorb moisture.

  • Decorate (optional). Spray paint or varnish the exterior for aesthetics. Get creative with patterns and designs!

Preheat and Cook Amazing Pizzas

You’re finally ready to fire up your DIY pizza oven!

  • Start by preheating for 30-60 minutes. This allows temperatures to reach 700°F+. Use a thermometer to monitor.

  • When preheated, prepare the pizza stone. Place parchment paper on top to prevent sticking. Sprinkle with cornmeal for a crispy crust.

  • Stretch and top the dough. Shape dough rounds into crusts. Top with tomato sauce, cheese and toppings of choice.

  • Slide pizza onto the stone. Use a pizza peel to transfer into the super hot oven.

  • Cook for just 3-5 minutes. Rotate occasionally for even browning.

  • Enjoy incredible homemade pizza! The fast, hot temps create a crispy, chewy, wood-fired taste.

So grab some cardboard and build your own portable pizza oven! With this simple design, you can cook pizza just like the professionals. Invite friends over for a DIY pizza party.
