Disaster Preparedness

Solar ovens are valuable assets during emergencies or natural disasters when conventional energy sources may be disrupted. They provide a reliable and independent means of preparing food.

How to Make a DIY Solar Oven

In this experiment, we are going to create a homemade oven that uses energy from the sun, rather than electricity, to heat foods to about 200°F. This is a great temperature for reheating leftover pre-cooked foods such as pizza. You can also use your homemade oven to melt cheese for nachos or to make delicious s’mores!

Required Materials

To build a solar oven, you will need the following materials:

  • A large pizza box with a lid
  • Aluminum foil
  • Black construction paper
  • Clear plastic wrap
  • Tape (preferably duct tape)
  • Scissors
  • Ruler
  • Pencil
  • Styrofoam or cardboard
  • Thermometer (optional but recommended)


Step #1. Prepare the Pizza Box

Begin by removing any grease stains or leftover food remnants from the pizza box. Ensure that it is clean and dry. Next, open the lid of the box and reinforce it with tape along the back seam to make it sturdier. This step is crucial to maintain the oven’s shape and prevent heat loss during cooking.

Step #2. Line the Interior with Aluminum Foil

Take a sheet of aluminum foil and cut it to fit the bottom of the pizza box. Use tape to secure it in place, ensuring that it is smooth and wrinkle-free. The aluminum foil will reflect and intensify the sunlight inside the oven, helping to increase the temperature. Remember to keep the shiny side facing up for maximum reflection.

Step #3. Create the Insulation Layer

To retain heat, the solar oven needs proper insulation. Cut a piece of styrofoam or cardboard to fit the size of the box’s bottom. Place this insulation layer on top of the aluminum foil, making sure it is snugly fitted. This layer will prevent heat from escaping through the box, ensuring efficient cooking.

Step #4. Line the Top with Black Construction Paper

Cut a piece of black construction paper to match the size of the pizza box’s lid. Attach it using tape, ensuring that it covers the entire inner surface. The black paper will help absorb the sunlight and convert it into heat, aiding in the cooking process.

Step #5. Create a Transparent Window

On the lid of the pizza box, cut out a square or rectangular window using scissors. This will act as a transparent panel through which sunlight enters the oven. Cover the opening with clear plastic wrap and secure it tightly using tape. The plastic wrap allows sunlight to pass through while trapping the heat inside.

Step #6. Assemble the Reflector Panels

To enhance the oven’s heating efficiency, construct reflector panels using aluminum foil. Cut two large rectangular pieces of cardboard or heavy-duty paper and cover one side of each piece with aluminum foil. Attach them to the sides of the pizza box using tape, ensuring that the foil faces inward to reflect sunlight onto the cooking area.

Step #7. Set the Oven to Harness Solar Energy

Go outside and find a good spot with full sunlight to use your oven. Adjust the angle of the flap to find the best sun angle for your pizza oven. Cut a plastic straw or wooden chop stick to prop up the flap at the angle you have chosen. Preheat your oven for 30 minutes by letting it sit in the sun and get warm.

Step #8. Preparing & Cooking Food

Now that your solar oven is ready, it’s time to start cooking! Place your food inside a dark, heat-resistant container and position it on the aluminum foil-lined bottom of the oven. Close the lid and align the oven so that it faces the sun directly. The cooking time will vary based on the dish and the sun’s intensity, so check periodically and adjust accordingly.
