Delicious Cheesy Leek and Potato Bake - easy to make and perfect to enjoy as a side dish or even a main course.

Cheesy Leek Potato Gratin
Who doesn't love a dish with potatoes and cheese? You won't ever see me raising my hand to that question.
Cheesy potato anything is just like the perfect combo. You could literally put it on the menu every single day and I don't think I would ever complain.
Add some leeks to the mix and well, that's heaven right there. Cheesy yummy Leek and Potato Bake - oh my!!

Best Potatoes for Gratin
I like to use Yukon Golds for this recipe, which are a semi waxy yellow flesh potato, they have a delicious almost buttery flavour.
But any potatoes will work well. I do recommend choosing a good quality variety for this.

Cheese Substitutes for Gratin
Feel free to use any cheese you like for the topping for this, so long as it melts well then it will work perfectly.
Don't like parmesan? Use cheddar, mozzarella, Gruyère whatever you fancy, just remember some cheeses are quite mild tasting, so may affect the overall flavour.

IN THE OVEN! I didn't have any mozzarella. I was generous with the Romano and Parmesan sooooo... fingers crossed!
Jonesy says
I do not like Parmesan cheese I find it too strong. Is there anything I can replace it with? Thanks
Shevy (Slimming Eats) says
You can use cheddar instead if you prefer. 🙂
Natalie says
What would you suggest serving with this? Thanks
Shevy (Slimming Eats) says
Hi Natalie, I usually serve it as a side with a protein-based dish - a chicken based dish would be perfect. http://www.slimmingeats.com/blog/category/recipes/by-ingredient/poultry
karen says
would this freeze.?
Shevy (Slimming Eats) says
Hi Karen, yes this will freeze fine.
Allison says
Hi, could you use Creme fraiche in this?
Siobhan (Slimming Eats) says
I am sure you can, I haven't personally tested, just ensure you count the syns as creme fraiche is not free.
Eve H says
I made this this evening with vegan parmesan and vegan feta in place of mozarella. It is the first potato and leek bake that I have made that was perfect - thank you so much for this recipe it's now going to be a weekly family favourite 🙂
Pamela Graham says
Perfect with our Monday dinner of cold roast chicken. Thank you
Jane Rawlinson says
I made this yesterday and we loved it! I was running short on time so I microwaved on high before I topped it with cheese. I then added the cheese and finished it off in the oven. I will definitely make this again and may try adding the cream cheese too.
Patricia says
Made this yesterday amazing thank you
Mary Carmen Bonnici says
It was delicious, but I made some changes due to lack of ingredients. Used both sweet potatoes and normal potatoes, used onions with leeks and beaten egg cheese and milk on top. My sons are both chefs and they liked it.
Siobhan (Slimming Eats) says
sounds delicious, thank you for sharing your variation and so happy to hear that your sons (who are chefs) also approved.
Bev says
Made this tonight 14/10/2021 and it was absolutely gorgeous I did make sure I seasoned it well with the black pepper and sea salt and i added extra garlic will definitely make again.
June says
I have made this versatile recipe several times. It’s great with roast, warms up well for cold cuts and is so tasty cold with salad. A firm favourite with us. Thanks.
