This super hearty, comforting dish is perfect for enjoying on those cooler evenings and is the ideal quick dinner, as well as being a great accompaniment to pretty much any dish.
We’ve used a mandoline to slice our vegetables, but if you don’t have one then you could use a knife instead – just try to get nice, even thin slices when you’re cutting.
You can use whichever colour of courgette you prefer as there’s no difference in taste. We do like the extra pop of colour that using half of a yellow one and half of a green one adds though!
It might be tempting to peel your potatoes, but leaving the peel on helps to give this dish a really lovely crunch and golden colour. If you’d prefer to remove the peel then you definitely can, but your dish may not be as crunchy or golden when baked.
This Cheesy Courgette Gratin doesn’t freeze particularly well, but it will be fine in the fridge for up to 2 days, so it’s perfect for portioning up and enjoying for a tasty lunch as well.

Hi, I have Diverticulitis and onion is one of my trigger foods. Would leek work as a substitute in this dish?
HollyTuesday 27th April 2021
Hey Barbara, yes leek would work great in this recipe, hope that helps!
Sam WSunday 18th April 2021
I made this and it was really good even though I’m not a fan of tomatoes but the work really well. The only problem I had is the ingredients say ‘ 1 stock cube made up with 25ml boiling water’ and it was no where near enough so I used 125ml water instead and this seemed to work. Not sure but I think this might be a typo?
HollyMonday 19th April 2021
Hey Sam, so glad to hear you enjoyed this recipe! 25ml is correct as the courgettes can release a lot of moisture if you felt like you needed a little extra just top it up with some boiling water. Hope that helps!
ClaireTuesday 6th April 2021
Just made this but had to put a lot more stock in & cream cheese but it tastes lovely xx
