Heirloom Sweet Potato Gratin

Try this spicy, smoky, savory heirloom sweet potato gratin recipe for something a little different.

For most of my life I have eaten sweet potatoes or yams in a syrupy, sweet form. When I was growing up we had them with marshmallows and brown sugar. When I was making them myself it was most often bourbon, pecans, and brown sugar…I love sweet potatoes when they are made like that but as time went on I learned to love them in other ways. Baked, sweet potato salad, and sweet potato hash… so many amazing variations besides just sweet!

For the Captain Morgan’s blog challenge I wanted to do sweet potatoes. After all, it’s close to Thanksgiving and I needed to do something with sweet potatoes anyway, right? I also just happened to have several pounds of heirloom Crimson Red Velvet sweet potatoes that I had picked up at the Dallas Farmer’s Market.

I wanted the dish to have a uniquely Texas twist to it and I wasn’t at all sure I wanted it to be sweet. I wanted to create something that was an update on traditional sweet potatoes, something creamy but also something that allowed the flavor of the heirloom variety to shine.

This Heirloom Sweet Potato Gratin is complex with smoky, spicy, sweet, and rich flavors and textures all tap dancing across your tastebuds like a scene in a Fred Astaire and Ginger Rogers movie. The potatoes are sliced thinly and layered with bacon and smoked gouda, then covered in a blend of chipotle, Captain Morgan’s black rum, half and half cream, and a little brown sugar and baked until the potatoes are tender and have soaked up the liquid.

If you make it a day ahead of time and warm it up when you are serving dinner it is even better! This is a great make ahead side dish that you don’t have to save just for the holidays!
