Zucchini casserole is one way to use up some of the vegetables from the garden. It's that time of year when there is so much to harvest. One thing that I love about having a garden is how it forces me into coming up with up new ways to use all the veggies that are growing. Over the winter, I decide what I'm cooking with, but right now, it's the garden that decides.

The zucchini seem to appear out of nowhere, and we have to watch carefully so that they don't grow into monsters. They are definitely best to eat when still on the smaller side. Not that they're  terrible when they get big. We once gave some neighbours a zucchini the size of a small child. They had a house full of teenage boys staying with them, so they stuffed it with ground beef and rice, baked it, and were able to feed their army with little fuss or expense. Usually though, we try to pick them before they get so huge.

Finding ways to use zucchini without getting tired of them is always a challenge, though. This zucchini tomato bake is one very delicious and easy way to make quick work of (yet another) zucchini, as well as those garden tomatoes that are ripening all at once.

A layer of potatoes goes on the bottom, which absorbs a lot of the liquid created by the vegetables when cooking. The topping is flavourful Parmesan and panko bread crumbs, giving it a nice, cheesy, crispness. You can easily make this zucchini tomato bake gluten-free by changing the panko crumbs for a gluten-free breadcrumb.

This fresh and flavourful casserole is great on its own with some crusty bread, or, as a side dish. Makes 6 servings.

  1. I’ll definitely be bookmarking this. I make a mean zucchini lasagna, but this is a nice twist on that and it uses up even more veggies with the potatoes! Your pics are beautiful. I’m now hungry.

    1. Thanks so much Tiffany! I love zucchini lasagna too. And thanks, I wasn’t really thrilled with the pics, so sometimes an unbiased comment makes all the difference! I think a lot of us food bloggers are too self critical sometimes. Have a great evening!

  2. This looks wonderful and such good timing as we still have these veggies grown locally. It is beautiful as well and love the crispy cheese topping.
