How we came up with this recipe

Boulangere Potatoes are similar to Dauphinoise, but instead they’re cooked in stock rather than cream (so they feel much lighter).

When my husband cooks lunch on a Sunday, this is one of those dishes I always ask for, so I knew at some point I needed to share it with you! Plus it has just 5 ingredients and NO any pre-boiling at all. 


Ingredients

Ingredients for Boulangere Potatoes laid out on a white counter. The shot from above shows potatoes, butter, stock cube, onion and fresh thyme.
  • Potatoes – Something like Maris Piper is perfect. The potatoes need to be a floury variety, not waxy so that they soften perfectly in the stock.
  • Onion – A regular white onion, peeled and sliced VERY thinly. (I use a mandolin.)
  • Vegetable stock – This should be boiling hot, just made up. Made with a cube is fine.
  • Fresh thyme – Leaves only. Strip the leaves from the woody stems and discard the stems.
  • Butter – I like to use salted, good quality butter here as it adds additional flavour. If you only have unsalted, add extra seasoning.

Top tips

Slicing

It’s important to slice the potatoes very thinly for this recipe. I used this handy chopping device for the job, which saves time.

Herbs

If you can, use fresh herbs here as they will give a much better flavour. Dried herbs tend to work better when cooked in a larger volume of liquid. If you do need to use dried herbs, halve the amount in the recipe.

FAQs

Do you know any other ways to jazz up potatoes?

Yes, try my Parmentier Potatoes.

For something a little more ‘humble’ go for my Colcannon (Irish mash), make-ahead Roast Potatoes, Air Fryer Baked Potatoes or delicious Homemade Chips!

What kind of pan should I use for making Boulangere Potatoes?

I use a medium sized heavy cast iron pan for this. Just make sure you use one that is safe to go in the oven, and perhaps something that looks nice in the middle of the table!

  1. Hi just looking at the roast beef and noticed your Boulangere potatoes… this also works well in the slow cooker under the meat don’t need much stock just a spay because the juices from the meat do the job. Usually do it with lamb but can’t wait to try it with beef.
    Thanks for all the recipes they’re a great midweek help!
