Healthy Sweet Potatoes Coconut Cream Au Gratin With Herbs And Spices

Last updated on

Spice up your dinner table with a garlic and herb infused Sweet Potatoes Coconut Cream Au Gratin. This is a much lighter and healthier version of a traditional dish!

Potatoes au gratin is definitely a comfort food for me. The creamy goodness and starchy potatoes makes me think of childhood potlucks and parties, where this dish was always abundant.

While potatoes au gratin is certainly delicious, it is of course usually made with white potatoes and cream-of-something canned soup. However, it’s possible to make potatoes au gratin with whole foods and still keep the cozy flavors. This casserole is made with sweet potatoes, coconut milk, herbs, and garlic.

I used white sweet potatoes (usually sold as “jersey yams“) for this recipe because I love how their creamy yellow color highlights the herbs. White sweet potatoes taste exactly like regular orange sweet potatoes, except they’re lighter in color. Don’t worry: They are not a nightshade.

If you aren’t able to find white sweet potatoes, feel free to use regular sweet potatoes or even purple sweet potatoes in this recipe. Using a mixture of assorted root veggies like turnips, rutabaga, carrots, and parsnips would be very delicious in this dish as well.

The rosemary in this dish sets off the sweetness of the root veggies, but you can swap it for thyme or your favorite herb. Make sure you let the casserole stand for the allotted time after it comes out of the oven; this allows the sweet potatoes to absorb any excess moisture from the sauce and enhances the flavors before you dig in.

This simple sweet potatoes au gratin recipe would be wonderful served with roasted meat or a fancier dish for a special dinner. It’s also an easy-to-make dish to bring to a potluck.
