Every year I make a solemn promise to myself that the next year I will not plant an excessive number of zucchini plants. Then, the very next year, I plant an absolutely silly number of plants for two people. Our son and his girlfriend don’t eat zucchini and trying to give them away in this rural area is like trying to sell sand at the beach. I’ve gotten pretty creative with how to use all the zucchini I produce and, since I also grow tomatoes and potatoes, my Garden Vegetable Casserole is a great way to enjoy our fresh from the garden goodies.
I was supposed to be taking it easy because of my fall but I just couldn’t resist using the fresh vegetables I gathered from the garden. Gathering the vegetables was also on my “you’re not allowed to do it” list but…
The first thing I need to do is a little prep work. I slice a medium onion, a medium zucchini, a large potato, and a couple of my Roma tomatoes all about 1/4 inch thick. I was excited to use my mandolin which my friend, Peg brought me when she came to dinner last week. It makes the prep work go really fast!
I cook the onions over a medium heat in about a tablespoon of butter until they are slightly caramelized. To help them caramelize I sprinkle a little salt on them as the cook.
I butter the casserole dish and lay the onions in a layer on the bottom.
Then I spread a layer of potatoes and lightly season them with salt and pepper.
Next a layer of the sliced zucchini is placed on top of the potatoes. I add a pinch of oregano on top of the zucchini layer. I’m also really proud that I grew and dried the oregano myself!
The top layer is the sliced tomatoes which are also seasoned with salt and pepper.
Covering the casserole dish with foil, I bake it at 400F for about 40 minutes.
I mix melted butter with Italian panko breadcrumbs and, when the 40 minutes is up, I spread the breadcrumbs over the entire dish.
I return the casserole dish to the oven and turn the heat up to 500F and bake the casserole an additional 5 – 10 minutes or until the bread crumbs are browned.
Chock full of vegetables this casserole is a great way to enjoy the best my summer garden has to offer!

It sounds delicious!!! I must try it with some of my garden veggies. And if only I were closer I’d take some of that zucchini off you 😉

It’s really good and I’d gladly give you some. I feel as though I’m in a 1950’s sci-fi movie…”Attack of the Killer Zucchini!”
