Materials & Tools

2 cardboard boxes. One should fit inside the other with two to three inches of space on each side. Make sure there is no Styrofoam in the boxes.


Aluminum foil

Plastic Wrap

Non-toxic tape—you don’t want anything in your oven that might give off toxic fumes when heated

Black construction paper





CRUMPLE up some newspaper and use it to line the bottom of the larger box.

PLACE the smaller box inside the large box and fill the two-to-three inch space around the smaller box with crumpled newspaper.

LINE the sides of the interior 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.

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

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

DRAW a line two-inches around the trace line and cut out to make a reflector.

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.

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

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

PUT your food in the solar oven. 13. Stretch clear plastic wrap across the top of the large box. Secure the plastic with tape around the entire box. Remember, it should take approximately double the time it would take to bake in a conventional oven.

Your solar oven should reach a maximum heat of 200 to 275°F. Don’t cook dishes that require high heat in a solar oven.
