Sweet Potato Gratin
September 24, 2019

The recipe as written is delicious. I did sub swiss for Gruyere because my local cheese counter was out and I couldn't find it elsewhere. I was concerned with my sweet potatoes fully cooking and baked 1/2 hour covered followed by another half hour to 45 minutes uncovered and my potatoes were still not done when I went to serve them. The potatoes had been sliced thin using my mandoline.
