One-Dish Sweet Potato-Chicken Gratin Casserole

Who doesn’t love a one-dish meal that’s ready in under 45 minutes? And that also happens to be a sweet potato casserole?

If you’ve been craving for some creamy AIP gratin packed with veggies & protein, then this one-dish sweet potato gratin casserole is exactly what you need!

One-Dish Sweet Potato-Chicken Gratin Casserole

Did you know?

1. This casserole also called “Gratin Dauphinois” originates from a province in southeastern France known as “Dauphiné”.

2. The name “Dauphiné” came from the word ‘dolphin’. The rulers of that province at that time had this aquatic mammal drawn on their arms.

3. The classic French gratin dauphinoise consists of:

  • Potatoes
  • Milk
  • Garlic cloves
  • Heavy cream
  • Sour cream
  • Butter
  • Gruyere cheese
  • Black pepper
  • Nutmeg

To prep this meal, make sure that you have the following ingredients on hand:

  • Extra virgin olive oil
  • Garlic
  • Red onion
  • Kale
  • Shredded chicken
  • Full fat, unsweetened coconut milk
  • Sweet potatoes
  • Fresh thyme

Ingredients Method Notes

Ingredients
  

  • 4 tablespoons extra virgin olive oil
  • 1 small red onion (⅛ pound), thinly sliced
  • 15 garlic cloves
  • 3 cups finely chopped kale
  • ½ pound shredded chicken
  • 1 cup full fat coconut milk
  • 1 handful fresh thyme
  • 3 medium sweet potatoes (¾ pound each), peeled and thinly sliced (abpit ⅛-inch thick)
  • 2½ teaspoons sea salt

Method
 

  1. Preheat oven to 400°F and lightly grease a large casserole dish.
  2. Pour the extra virgin olive oil in a large skillet. Then add the minced garlic and sliced onion. Let it sauté for about 1 minute.
  3. Add the chopped kale and shredded chicken. Sauté for another 3 minutes over medium heat (until all the kale has wilted.)
  4. Pour the coconut milk into the skillet along with the thyme. Bring to boil.
  5. Then toss in the sliced sweet potatoes and salt. Bring to simmer and cook on low heat for about 7-10 minutes.
  6. Carefully transfer everything to your casserole dish.
  7. Bake for 15-20 minutes until the sweet potatoes are fork tender and have absorbed all the coconut milk. *See notes below

Notes

1. This sweet potato gratin tastes best when freshly cooked but you can still refrigerate it for 1-2 days in an airtight container.
2. Want your gratin to be slightly wet? Bake it for 10 minutes instead of 15-20 minutes.
3. The baking time will vary depending on:
  • the thickness of your sliced sweet potatoes,
  • the type of sweet potato you used,
  • where you live, and
  • how hot your oven is.

    This is absolutely delicious! I accidentally put a little too much salt but even so, the flavor is just wonderful. It’s also fairly quick and easy to put together. I will definitely be making this often!

    (I did use garlic infused olive oil in lieu of the garlic cloves because LOWMAP.)

    This was truly amazing! I used spinach instead of kale, as that is what I had available. I know I will be making this often, it is so GOOD!
