What goes into the recipe

ingredients for sweet potato, bacon and leek quiche: shortcrust pastry, sweet potato, cream, leek, bacon, eggs, cheese, butter, thyme

sweet potato - not only is it a nutritional powerhouse, but sweet potato tastes great and is super versatile. I have used it so much on the blog, that I've got a post all about sweet potato for kids! Grating it into this recipe and cooking it with the bacon and leek means it ends up deliciously sweet and also savoury.

leek don't have one? Swap for 2 onions, but be warned, you will need to caramelise them for longer to get the same sweetness that you get from leek. I love leeks and they are so easy to grow in the garden!

bacon- this was 4 rashers of streaky bacon, but they were chopped in half to fit in the fridge. I feel streaky bacon is a good option here as it has more fat and more flavour, and therefore adds more to the sweet potato mix.

shortcrust pastry- I've used Pampas brand, whatever you find is fine. If you would prefer to make your own crust, the shortcrust in this recipe will work just fine.

dried thyme- it's such a simple flavour, but it works super well with sweet potato and leeks and therefore is our flavour of choice. This quiche is quite mild in flavour, so if you want more flavour, you could also add paprika, or even a little bit of chilli. I wouldn't recommend adding more salt, as the bacon is already salty and any extra salt will overwhelm the sweetness of the sweet potato and caramelised leek.

Expert Tips and FAQS

There is no need to spend time making your pastry perfectly fit for this dish. That's why I pop a sheet down on the bottom and cut the second into thirds, wrapping around the dish and folding over.

Why do we cut and paste the pastry?

Because it's simple! Shortcrust pastry comes in sheets and this is the easiest way to make a quiche case! I can't be bothered measuring, re rolling and organising it to perfection and for this recipe you don't need to!

Can I use already cooked sweet potato?

Yes, you can, but don't cook it with the bacon and leek, instead just stir the bacon and leek through the cooked sweet potato.

How do I store this quiche?

For 2-3 days in the fridge. It will be fine either cold, or heated up for meals.

Can I freeze this quiche?

Yes! I freeze in slices, for convenience. If you are making this in advance for a picnic you don't need to slice first, but if you're keeping it for lunchboxes, or easy dinners, slicing is best. It will defrost just fine in the fridge or you can reheat in the oven , sandwich press or even the airfryer!
