Solar Potatoes and Onions au Gratin

Vegetables done au gratin can be very impressive, even though they are very easy to prepare. Never able to leave well-enough, alone, I just had to add onions to the potatoes and came up with a very tasty dish.

This is a case where the vegetables are at odds -- the potatoes are dense and the onions are not, so we have to balance the cooking process. Give the sliced potatoes a head start with a 2-minute zap in the microwave before layering them in your casserole. It's not cheating; it's what a multi-tasking cook does!

Potatoes and Onions au Gratin
3 medium red potatoes, thinly sliced
2 medium onions, thinly sliced crosswise
1 tsp salt
1/8 tsp black pepper
1.25 cups chicken stock
1 small can evaporated milk + 1 can hot water
1 tsp powdered cream
1/8 tsp garlic powder
1 tsp parsley
1/2 tsp dill leaves
1/2 cup shredded cheese of your choice

Preheat solar oven to 225F. Lightly grease casserole.  Alternate layers of potato and onion in casserole, starting and ending with potatoes. In large tempered glass measuring cup, blend liquids with herbs and spices; zap in microwave for 2 minutes; pour over potato-onion layers. Cover and bake in solar oven for 70 minutes; uncover, spread shredded cheese over top; return to solar oven and bake for an additional 45 minutes or until top is golden brown and potatoes are fork tender.

Do you have a special au gratin recipe?


  1. Yum....this sounds delish. I love Potatoes au Gratin and I love potato and onion combinations.

    Thanks for the idea, though I must shamefacedly confess I do not have a solar oven and will have to resort to the usual gas stove. I do believe in Solar cooking though.....I am just too lazy.

    1. It's one of my favorite comfort foods. Some folks add those crispy onion rings, but I like it plain. You don't have to solar cook to enjoy this, either. Thanks for stopping by, Lo.

  2. I'm all about your kind of not-cheating! Anything that can hurry along potatoes au gratin is a winner in my book. These look fantastic. I'm a big fan of adding onions too, though I know some don't like them.

    You know I'd be all over the solar oven thing if I could do it. Someday, doggonit.

    1. That's exactly why I think solar cooking will work for the mainstream -- use all appliances (110v type) to help the oven. It's not an adversarial thing -- just makes money sense. I know you'd be doing it, too, and maybe the day will come. If not, at least, you can spread the word. And, remember, my recipes work just as well in a conventional oven at the lower temp that will help reduce fuel bills, too! Thanks for stopping by.

    1. Yes, just enough to make it pop. I love trying new combinations. You never know what the result will be, but age has at least given me a sense of what will work better than just any combo. Thanks for stopping by. Hope all is well in your neck of the woods.

  4. Thank you for writing these details on the internet.
