  1. Select the right box

    Choose a sturdy box that is large enough to hold the cooking container. It should have an attached lid.

  2. Cut the oven door

    Mark a line 1 inch from three edges of the box lid. Use a box cutter to cut along the line, leaving the flap attached at the back of the box.

  3. Cover the inside with foil

    Use glue to attach aluminum foil to the inside of the box. Cover the inside of the cardboard flap with foil. Keep the foil as free of wrinkles as possible so it forms a mirror-like surface.

  4. Create a window

    Use tape to attach plastic wrap to both sides of the opening surrounding the flap.

  5. Test the oven

    Lift the box lid to place the food inside the oven. Close the lid. Turn the oven so the sun reflects from the flap through the window onto the food. Use a stick to prop the flap in position. Adjust the position of the oven and flap as the sun moves while cooking. Once the food is ready, open the lid and use oven mitts to remove it from the oven.
