Potato, Tuna & Mushroom Gratin

This Potato, Tuna & Mushroom Gratin is adapted from the recipe for Gratin of Potatoes, Onions and Anchovies from Julia Child’s infamous “Mastering the art of French Cooking“. The first time I cooked the Gratin, I followed her recipe to the letter – only to discover that neither myself nor anyone in the family is even the slightest bit fond of anchovies!

I had wondered why I didn’t cook with them more often and after the first fishy bite of the Gratin I knew why – it’s just TOO fishy for my tastes. (No offence to anyone who is fond of anchovies!)

So, I re-jigged the recipe, including family favorite flavors such as tuna, mushrooms and cheese and we have a winner. Comfort eating at it’s yummiest!

 

The Gratin is incredibly simple to prepare. You boil the diced potatoes until just tender as they will have further cooking time in the oven.

In a frying pan, soften the mushrooms and onions, helping build flavor for the gratin they become.

Then, it’s simply a matter of putting all the elements together in a large dish.

Finally, cook in the oven for 35 minutes, and you can indulge in a deliciously comforting Potato, Tuna & Mushroom Gratin.
