Butternut Squash +
Sweet Potato Gratin


My husband’s grandmother makes a mean potato gratin. It’s a dish that is synonymous with Thanksgiving in his mind.

So this year, as we were booking tickets to visit my family in Tucson for the holiday, it was one of the first things he asked about – “Please tell me there’s going to be potato gratin,” he implored.

Hesitantly, I informed him that my family usually makes candied sweet potatoes instead of gratin. The disappointment in his face was unmistakable. “Don’t worry I responded, I’ll come up with something that will make everyone happy.”

Sweet potato gratin – a perfect solution to please all parties. The creamy comfort of gratin combined with caramelized sweet potatoes. Everybody wins.


And because the rd-to-be in me can’t help but up the nutrient ante of every meal I create, I tweaked a few key elements to make this dish extra nutritious.

Low-fat organic milk from Clover Organic Farms replaces the half and half found in traditional potato gratin recipes, while part-skim cheese adds flavor with reduced saturated fat.


Butternut squash is an excellent source of vitamin A, vitamin C, and phytonutrients called carotenoids, which are antioxidants that may reduce the incidence of cardiovascular disease and some cancers.

Combining the squash and sweet potato with dairy, and cooking it, is a strategic move. Fat helps improve the bioavailability of carotenoids.


With eight simple ingredients, this butternut squash and sweet potato gratin is the perfect healthy holiday dish that still invokes those nostalgic feelings of Thanksgiving past.
