Truffled Potatoes au Gratin
A classic recipe dressed up for special occasions, humble potatoes are bathed in a truffle studded cheese sauce and baked until tender. Truffled Potatoes au Gratin are very simple to make and are a stellar addition to any dinner.
Growing up, one of my favorite side dishes was Potato Gratin. It came from a box, had a powdered cheese sauce and always tasted completely, insanely amazing. Potatoes baked in a cheese sauce (real or not) was always the way to turn my smile upside down…..even if it was piled high next to a slab of liver or a chicken croquette.
It kind of took the sting out of my main course. I still will whip out the box, on occasion, if dinner needs to be on the table in a hurry like this one-pot chicken casserole but there’s nothing quite like making Au Gratin Potatoes from scratch. Especially, if you have a bunch of truffle butter lying around.
So, when D’artagnan Foods contacted me to create a recipe using some of their products I jumped at the chance. I’ve been using their duck and truffle products for years. It was my way of eating a king’s meal on a poor girl’s budget in my 20’s.
Their Black Truffle Butter is amazing and filled with true truffle flavor. It’s easy to infuse any dish with that rich, earthy black truffle essence without breaking the bank and is completely bonkers in this Truffled Potatoes au Gratin recipe. And really, when you tell your dinner guests a dish has black truffles in it…they get all excited and think that they’re something special because you sprung for truffles! 🙂
These Truffled Potato au Gratin are so simple to make. I made my favorite, from scratch, Potatoes au Gratin (which I now realize is not on my site…fixing that soon!) and replaced the butter with the black truffle butter. Instead of the traditional cheddar cheese, I substituted a mild, creamy Havarti so the flavor of the cheese would not overpower the truffle.
It was the perfect blend of smooth, velvety, earthiness that I was looking for in a sauce. It enrobed the potatoes just beautifully and after it was finished baking, a golden cheesy crust developed making it a dish hard to resist digging into while I was shooting the photos. The whole recipe takes less than 30 minutes to prep and you can make the dish ahead of time…baking just before serving making this the perfect side dish for the holidays.
So, there you have it…my life saving childhood side dish made a little more sophisticated. What’s your favorite childhood dish all grown up?
