Potato Casserole – Kitchen Staples Recipe

Plate with potato and zucchini casserole


I was first introduced to this potato casserole a year ago. I was visiting family out of town and we had plans for dinner. 


Our host was very kind and tried her best to cater to some food sensitivities that I had then. Long story short, pregnancy had me go dairy and gluten free overnight. I also had to quit chocolate, caffeine, raw veggies and more.

Having to deal with so many limitations would have set anyone off. But not her. She came up with this recipe that is not only delicious but super versatile too. All five of us were raving about it.

The original recipe used mushrooms too, but since I didn’t have any on hand I just omitted them. You can also substitute any other veggie that you have in your fridge for the zucchini. Potatoes make a good base for most vegetables. And I am willing to bet that you can even use any frozen vegetable that you might have in you freezer to make it.

Since now most of us are trying to stay away from the shops as much as possible our buying habits have changed. We tend to buy more food that has a long shelf life. Potatoes store really well and are a staple in almost every house. 

And I have yet to meet a person who doesn’t like them!

I wanted my veggies very thinly sliced so I put my food processors’ slicer to good use. I would highly recommend you do the same. You can also use a mandolin or the wide vegetable cutter on your box grater.

I hope you give this casserole a try. You can even serve it as a side dish. But be prepared for it to steal the show.

Don’t forget to tag me @olivetreemeals. I loooooove seeing your dishes. I feel like I am invited over for dinner!
