Zucchini, Tomato and Potato Casserole
Harvest from your summer garden and make this delicious Zucchini, Tomato and Potato Casserole recipe! Itโs a perfect summer side dish for veggie lovers!
If you have a garden full of zucchini (or summer squash or courgette or whatever you choose to call itโฆ) you are probably looking for delicious ways to use it up.ย I came across some beautiful local organic yellow zucchini and knew I had to come up with something to really showcase the flavour and colour.ย Just look at that vibrant yellow!
This casserole is a perfect side dish for many summer meals.ย ย Caramelized onions line the bottom, with layers ofย sliced of zucchini and potato with a final layer that is carefully and beautifully arranged to include tomato.ย It is then topped with basil and almonds.ย This recipe was inspired by this recipe in Southern Living.
It didnโt take me long to prep but my knife skills are severely lacking.ย I wish I had a mandolin when I was doing this.ย I do have a food processor but Iโve never used the slicing blade and didnโt think this was the time to try.
It is important to try and get an even thickness with your slices though so that it all cooks evenly.
