Solar Cooking: Hard-Boiled Eggs

I got a new toy that I wanted to share with you.  We purchased a Global Sun Oven to try some free-energy cooking. You can bake, boil and steam with it and also dehydrate. It doesn’t matter what time of year it is, the Sun Oven is supposed to be able to get up to 400°, even in winter (It was 40° today).


So it arrived this week and I decided to start off easy: hard-boiling eggs without water. On a full sunny day it should take 35 minutes to hard boil the eggs.  We had a partly sunny day. So it needed more like an hour and a half.


The temperature got to 230 degrees in about 20 minutes and topped off at 260.


Eggs are cooked in their cardboard holder. You can fit 2 dozen in the oven.

However, I didn’t think this through properly. We started late in the day and the sun was low in the sky, then it set before the time was up. The eggs were very good, but closer to soft boiled. I peeled them (even fresh eggs peel super easy with solar cooking) and made egg salad for dinner. Not bad for a 40° winter day!


A little underdone as the sun did not cooperate and set!

I am trying a pork roast on the next sunny day we have.

If you are ever interested in purchasing one, always check the internet for a coupon. I think they run them fairly constantly for different packages. We got the package that included 3 dehydrator racks, 2 pots with lids, 2 bread pans, a turkey roasting rack (will cook an 18lb turkey in a roasting bag), and a water pasteurizing indicator. Our coupon took off almost 1/3 the price and shipping was free.

    We’ve been wanting to get one of those for quite some time. Glad to see it worked and I’m sure the temp would have gotten higher if it was started earlier in the day. We did purchase a Crises Cooker some time ago and have used it several times. It only took half the amount of charcoal to cook steaks and if you take the briquet’s and dump them in cold water as soon as your done cooking they can be reused again. Simply remove them from the water and let them dry out in the sun for several days. So you can store a lot of charcoal cheaply and it will last a lot longer then you think.

    My experiment with storing the chicken feed (pellets) worked out well. I had two 5 gallon buckets and added an oxygen absorber in each one and then sealed the bucket. It was last Feb when I did this and I opened one bucket last October and used it with no ill effect and had the same result at the end of Jan when I opened the second bucket and used it. The eggs seemed normal and the hens didn’t show any ill effects from the storage.

    That is very cool. About what do they run and how big is it? I wonder if Bass Pro has them and runs sales on them, too.
    Be careful the government doesn’t tell you they are illegal b/c you are using “their” sun. They are already claiming rainwater run off is theirs in some areas of the US!!!!!!
    Your package sounds like a good one.
    Have fun! 😉

      You should come over and see it! It’s pretty big, like a kitchen sink (dumb, but that’s what it reminds me of size-wise). Hit the link in the beginning to see prices. There are a bunch of variations with different prices.

  3. This is really neat. i’m very impressed. I can barely manage to cook with an oven, much less something like this. haha Thank God my husband likes to cook or my family would starve. This seems like a cool thing to have though, glad it worked well and hope you enjoy it!

    Make sure you use a meat thermometer when roasting your pork. Slow is good, thorough cooking of pork, in particular, is essential.
    Ireally like this idea for “boiling” eggs, but probably won’t purchase a solar oven just for that
