Tips for successfully preparing gratin

  • You can slice the potatoes in advance to make the dish easier to prepare. Simply store them in a bowl of ice-cold water in the fridge and then pat them dry before using them in the recipe. They are fine up to 24 hours in advance.
  • The gratin can also be prepared in advance. Allow to cool to room temperature and store in the refrigerator for up to two days. To reheat, remove from the fridge and bring to room temperature for 30 minutes while the oven heats to 180°C to prevent a cold dish from cracking in a hot oven. Once the oven has heated up, cover the gratin with aluminum foil and reheat for about 20 minutes or until warm and bubbly.
  • Another way to serve the gratin is to let it cool and then cut it into slices. Place the rounds on a greased baking sheet and heat in a 350°F oven for about 10 minutes.

“This recipe is the epitome of a made-from-scratch potato gratin. Although it takes time to prepare the potatoes and other ingredients, it was tiring but worth the effort. The recommended cheeses are a little more expensive than some other options, but the combination of Gruyère and Brie make this dish great.” –Colleen Graham
