Make a Solar Oven- Have Fun with a Different Take on Boxing Day

Tis the season for too many empty boxes around the house.  Tis also the season for trying to figure out what to do with the kids home from school.  If you are feeling adventurous, here are the step-by-step instructions for using some of those boxes to create your own solar oven. 

Things You’ll Need

  • Aluminum Foil
  • Cardboard
  • Large And Small Cardboard Boxes
  • Non-toxic Glues
  • Non-toxic Invisible Tape
  • Plastic Wrap
  • Scissors
  • Newspaper
  • Pencils
  • Black Construction Paper
  • Staplers


Step One

Find two boxes. One should fit inside the other with a 2- to 3-inch space on each side. (This can vary slightly – the space will be filled with newspaper.)

Step Two

Line the bottom of the large box with crumpled newspaper.

Step Three

Place the smaller box inside the large box.

Step Four

Fill the space between the sides of the two boxes with crumpled newspaper.

Step Five

Line the sides of the inside of the smaller box with aluminum foil. You can use a non-toxic tape or fold the edges of foil over the top of the box to hold it in place.

Step Six

Line the bottom of the inside of the smaller box with black construction paper to absorb heat.

Step Seven

Lay a piece of cardboard on top of the large box and trace the shape of the box onto the cardboard.

Step Eight

Add 2 inches around the trace line and cut out to make a reflector.

Step Nine

Cover the cardboard piece with aluminum foil. Smooth out any wrinkles and secure the aluminum foil to the cardboard with non-toxic glue or tape.

Step Ten

Staple the reflector to the outside back of the large box.

Step Eleven

Situate the oven with the box opening up and the reflector facing the sun for maximum heat.

Step Twelve

Place food to be cooked in the solar oven.

Step Thirteen

Stretch clear plastic wrap across the top of the large box. Secure the plastic with tape around the entire box.

Tips & Warnings

  • Cooking time is about twice as long as in a conventional oven.
  • Preheating takes about 30 minutes.
  • Use bigger boxes for a larger oven.
  • A small pizza box oven is good for kids to make s’mores or mini-pizzas.
  • Do not use any materials that could give off toxic fumes when heated, such as duct tape or Styrofoam.
  • Do not use a solar oven for foods that must reach a high temperature or cook rapidly.
