Milk Calendar Hearty Sweet Potato Au Gratin

Sweet Potato Au Gratin is the ultimate comfort food casserole recipe.

Thinly sliced sweet potatoes, smothered in a cream sauce, topped with cheese. Hearty and delicious.

This au gratin potato recipe was originally posted in the 41st edition of the Milk Calendar and I shared it in December 2017 as a sponsored post.

I was thrilled when I was asked to recreate the January 2018 recipe Hearty Sweet Potato Au Gratin because I am a potato lover.

I was so excited when I was asked to take part in the #MilkCalendar campaign that year. My fridge is ALWAYS stocked with several varieties of cheese. I use it in delicious recipes for any meal of the day. When I want a snack, crackers and cheese are my “go-to” options most days of the week.

RECIPE and INSTRUCTIONS for this sweet potato gratin recipe can be found at the bottom of this post.

These scalloped sweet potatoes are simple and oh so delicious. Cheese is the most important factor in au gratin potatoes.

• This will take about 4-5 minutes.

Step THREE:
