To sun-cook fava beans, you'll need a simple solar oven made from a cardboard pizza box lined with aluminum foil and covered with plastic wrap. Position your oven in direct sunlight between 11 am and 3 pm, and preheat it for an hour. Select fresh, firm fava pods with slight bronzing, then soak, drain, and peel the beans before cooking them in water inside your solar setup. Check every 10 minutes until tender, which typically takes 10-45 minutes. Season with olive oil, garlic, and lemon juice for a Mediterranean flavor. The combination of proper setup and timing holds the key to perfectly tender, sun-cooked fava beans.
Preparing Your Solar Cooking Setup

Ready to harness the sun's power for cooking? You'll need to build a simple yet effective solar oven, which you can create from a basic cardboard pizza box.
Start by cutting and folding the box to form your cooking chamber, then line the inside with aluminum foil for maximum light reflection.
Add black surfaces inside to absorb heat, and use newspaper as insulation between the walls.
To trap heat effectively, you'll need to cover your cooking chamber with clear plastic wrap or glass. Position the reflective surfaces at angles that concentrate sunlight into the chamber.
You'll want to set up your oven in direct sunlight, specifically between 11 am and 3 pm when the sun's rays are strongest. This method of cooking is completely sustainable and doesn't require any fossil fuels.
Before cooking your fava beans, preheat your solar oven for up to an hour.
Don't forget essential safety measures: wear protective eyewear during setup, place your oven on a stable surface, and never look directly at the sun while adjusting the reflectors.
Keep a thermometer handy to monitor the internal temperature, and you'll need to rotate the oven periodically to follow the sun's path.
Fresh Fava Bean Selection
Now that your solar oven is set up, let's focus on selecting the perfect fava beans for sun cooking. You'll want to choose firm, heavy pods that resemble giant green beans with slight bronzing on the exterior. These ancient cultivated plants have been feeding humans for over 10,000 years, making them a time-tested addition to any meal.
Look for pods that are full from end to end, avoiding any that show discoloration or shriveling.
When you're at the market, you'll find fresh fava beans primarily during spring. If it's not the growing season, check the frozen food section or visit Middle Eastern and Greek markets for dried alternatives. Remember that smaller pods are ideal if you're planning to cook them whole.
Picture the perfect fava bean pod by checking these essential qualities:
- The pod should feel substantial in your hand, with subtle bumps indicating plump beans inside
- The exterior should maintain a consistent green color with minimal markings
- When gently squeezed, the pod should feel firm but not woody or brittle
Once you've selected your beans, store them in a plastic bag in your refrigerator's crisper drawer if you're not cooking them immediately. They'll stay fresh for up to 10 days, though younger beans should be used sooner for the best results.
Sun Cooking Time Requirements

After soaking, drain and rinse your beans thoroughly.
You'll need to peel them by gently squeezing each bean between your thumb and forefinger.
While specific sun cooking times aren't standardized, you can use conventional cooking times as a baseline.
Add your peeled beans to 10 cups of fresh water and place them in your solar cooker.
You'll want to check your beans every 10 minutes, as cooking times can range from 10 to 45 minutes depending on bean size.
They're done when they're tender but not mushy.
For extra flavor and authenticity, consider adding two cloves of garlic during the cooking process.
Remember to use fresh water for the cooking process, as this helps prevent digestive discomfort from oligosaccharides present in the soaking water.
Seasoning During Solar Cooking
During the solar cooking process, seasoning your fava beans requires a thoughtful approach to achieve the best flavor. Start by placing your beans in a large pot with plenty of water in your solar oven, and don't forget to reserve the cooking liquid for later seasoning adjustments. Since fava beans have a natural buttery texture, you'll want seasonings that complement rather than overpower this characteristic.
For a traditional Mediterranean-style seasoning blend, you'll want to combine olive oil, garlic, and lemon juice as your base. Then, enhance the flavor profile with cumin, paprika, and a pinch of cayenne if you're looking for heat. You can adjust the consistency using the reserved cooking liquid, ensuring your beans aren't too dry or too soupy.
Here's how to layer your flavors for maximum impact:
- Start with the olive oil base and aromatics (garlic, herbs) while the beans are still warm
- Add your spice blend (cumin, paprika, cayenne) and salt, stirring gently to combine
- Finish with a splash of lemon juice and adjust seasonings to taste
Remember to taste as you season, and don't be afraid to experiment with different herbs like thyme, rosemary, or bay leaf to create your perfect flavor combination. The key is finding the right balance between earthy spices, bright acids, and aromatic herbs.
Serving Solar Cooked Favas

Fresh from your solar oven, fava beans transform into versatile ingredients that shine across multiple serving options.
Transfer your cooked beans to a food processor, adding garlic, olive oil, lemon juice, and seasonings like cumin, paprika, and cayenne. You'll want to mash them to achieve your desired consistency, adding reserved cooking liquid as needed. Using the Cook'n Recipe Window, you can customize your recipe to adjust seasonings and ingredient amounts to match your preferences.
You can serve these sun-cooked favas in various ways. Create a delicious dip by garnishing with fresh herbs and a drizzle of olive oil, or incorporate them into salads for added protein. They'll work wonderfully in soups or as a side dish alongside roasted vegetables. For a complete meal, mix them into rice or pasta dishes.
For storage, keep your cooked favas in the refrigerator for short-term use or freeze them for later. When you're ready to use frozen beans, thaw and reheat them gently by simmering in water or broth. You'll maintain their texture and flavor by following proper storage techniques.
Remember to taste and adjust seasonings before serving, whether you're enjoying them warm or cold.
