dairy-free potato gratin

When it comes to food, Jon and I are so similar yet so different. We both favor home cooked meals above all, we both can’t get enough of desserts and veggies, and we both love watching all TV shows about cooking — from Top Chef and MasterChef to even the most random documentaries about culinary events and products. But then there’s steak, which Jon could eat every day while I can’t even swallow a single bite. And then there’s cheese, which I can’t live without while Jon can’t stand most of the varieties. Finding out that I was lactose intolerant in October literally shattered my world, making me change my whole diet that mainly consisted of dairy products and fresh produce. Luckily pills exist to help my body digest lactose, as well as so many lactose-free products that allow me to continue enjoying my favorite foods. Nevertheless, I’ve challenged myself to recreate many of my favorite dishes in dairy-free versions, from lemon meringue pie all the way to this creamy, crispy, and just-unbelievably-perfect potato gratin.

Known as well as gratin dauphinois, potato gratin is created out of layers of uncooked thinly sliced potatoes that are cooked with cream in the oven until crispy. Some top the dish with Parmesan or Cheddar cheese and others add vegetables between the layers, but I decided to stick to the original French version and substituted the cream for a dairy-free homemade béchamel sauce.  Béchamel sauce is typically made by cooking butter and flour to make a roux and then whisked together with milk until thick and creamy. I chose to use margarine instead of butter and soy milk instead of regular milk, following the same steps to make this white sauce. The result was mind-boggling — it tasted identical to the real deal and made my potato gratin such a success.

My potato gratin consists of three different layers — sauce béchamel, potatoes and onion — which are stacked on top of each other until you’ve exhausted all of your potatoes. Making this recipe is much easier if you own a food processor, as thinly chopping the potatoes and onion is a must to create a crispy gratin. Slicing them up in the food processor takes less than 3 minutes, but if you don’t own one I still urge you to give this one a go. It will take some time but it’s well worth the effort.

Recipes like this don’t make me sad about cutting out dairy from my diet — on the contrary, they make me happy since they’ve pushed me out of my comfort zone and given me the power to be even more creative in the kitchen. With all the wonderful products out on the market today, all one needs is a bit of creativity to work with substitutes to recreate favorite dairy-free dishes. Jon was happier than ever since I didn’t include any cheese in the recipe, and as we both love potatoes, we were so happy to share this dish together!

    Oh, I love potatoes, and this recipe, and your photos look so yummy, I wish I were at home right now so I could start cooking it…

    I’m sorry to hear you are lactose intolerant, it might be hard have to give up on foods you love, but it’s good you are creative and found a way around it to keep making the recipes you love.
