What is the best durable solar oven for large batches

I’m really considering buying or building a solar oven. However, I need another project like I need a hole in my head, and the ones I see for sale seem kind of chintzy. I’m intending it for three season use- using the oven when it’s near zero degrees out doesn’t feel wasteful, but running the oven when it’s 70 degrees is kind of creating a problem.

Ideal solar oven:
-Big enough to cook loads of potatoes for chickens and pigs.
- super ideal but I know it’s unrealistic: can be used to boil down sauces and broths
- easy to clean!!
- minimal use of plastic
- durable and ready to go to work more days than not (I see a lot of solar ovens that look like cheap junk marketed to campers wanting a lightweight camping oven, where I want something sturdy that stays in one place.)

I have a solar oven that is adequate to cook a meal, but it is not going to cook loads of anything.   I suspect youroven will have to be constructed as a home project.

Wood is stored solar energy.
I would build a rocket stove and get a big pressure cooker.
