Sometimes you just want to eat something warm, hearty, and enhanced by melted cheese! There's nothing like a gratin dish to accomplish that all at once. While traditional versions of potatoes au gratin include white potatoes and larger ratios of cream and cheese, this one makes a few nutritious swaps – namely, using sweet potatoes and a more careful use of seasoning and dairy.
Skill level: intermediate. Serving size: 1/2 cup, or approximately 1/8th of pan.

  • 4 medium-large sweet potatoes, rinsed and cut into slices 1/8th of an inch thick
  • 1 cup half and half
  • 2 whole garlic cloves, peeled and minced
  • 1 1/2 tsp. smoked paprika
  • Salt and pepper to taste
  • 1/2 T. coconut oil (or oil of choice), melted
  • 1/2 cup havarti cheese, grated


  • Preheat oven to 350 degrees.
  • Slice sweet potatoes and set aside. Make sure to slice thin (use a mandoline slicer if possible).
  • In a small mixing bowl, combine half and half with minced garlic and seasoning. Set aside.
  • Grease 9" x 9" or medium-large casserole pan with oil.
  • Layer the sweet potatoes in the pan. Spread them out as evenly as possible – there will probably be 3-4 layers. 
  • Pour half and half mixture on top of the potatoes. 
  • Bake for 30 minutes or until potatoes have softened. Remove and sprinkle shredded cheese in an even layer over the top.
  • Bake additional 10 minutes or until cheese has slightly browned.
  • Allow to cool for 5-10 minutes before slicing. Enjoy!
