Sweet Potato Gratin

Sweet Potato Gratin are sweet potatoes drizzled in a dairy-free "cream" sauce. This Vegan and Paleo dish makes an easy side dish to a family dinner or a delicious to your holiday table.

Oh man guys. I could not live without potatoes especially sweet potatoes or yams. They're a staple in my house and one I can never get enough of. Last week I posted another Whole30 casserole on my Instagram feed and someone asked how can you eat potatoes and lose weight.

Say whahathahat? Of course you can eat potatoes and lose weight. In fact, you should eat potatoes. They're good for you! Anything that comes from nature can and should be eaten. It's when we eat too much of a certain food group or too many boxed, canned or packaged foods that it leads to problems.

That casserole in fact was on my high protein low calorie meal plan and my friends could not believe they were actually able to eat such delicious foods that are healthy. It's about balance and moderation and I do all the balance for you on the back end of those meal plans so you don't have to think about it!

No one should eat an entire batch of that casserole or healthy Sweet Potato Gratin in one sitting just because it's "healthier."

Easy Sweet Potato Gratin

This Sweet Potato Potato Gratin recipe is a healthier and lighter version of au gratin and it's one of my holiday go to recipes. It replaces heavy cream with a thick and delicious Vegan friendly cashew cream sauce. The same sauce I used in my Creamy Brussels Sprout Bake. Another holiday recipe for you to add to your list!

Cashews add healthy fat to this recipe in just the right amount. This is key to making recipes filling so you DO NOT over eat them. Potatoes are a healthy carb, but it's easy to go overboard. The healthy fat prevents that!

What You Need

• Yams or sweet potatoes
• Cashews
• Onion
• Dairy-free milk
• Rosemary
• Garlic
• Parsley

How To Make Dairy Free Sweet Potato Au Gratin

Start by soaking the cashews in a bowl of water 2-3 hours. Drain the cashews then place in a food processor with water, lemon and milk. Blend on high until thick and smooth. You can adjust the texture by adding more or less milk. Add the spices (omitting the rosemary) and blend once more.

Slice the sweet potatoes to about 1/4 to 1/2 inch thickness and place in a baking dish greased with a little extra virgin olive oil. Place the sweet potatoes in the dish layering the bottom of the dish first then layering over each other.

Pour the cashew cream sauce over the top, sprinkle the onions and rosemary over the top, bake and eat!

Helpful Tips

To make this dish nut free, replace the cashew, milk, water and lemon with 1 cup coconut cream and 2 tablespoons of tapioca flour.

Any potato can be used in this recipe. I just love the natural sweetness of yams and how good they taste with the cashew cream sauce!
