  • Prep Time: 15 min
  • Cook Time: 55 min
  • Total Time: 1 hour 10 minutes
  • Yield: 4-5 servings 1x



  • 34 pounds sweet potatoes, washed and peeled
  • 8 tbsp salted butter or ghee 
  • 3 cloves garlic, minced
  • 1 tbsp fresh herbs, minced (any combo of rosemary, thyme and sage)
  • salt



  1. Preheat oven to 375’F.
  2. Melt butter (or ghee) in a small pot.  Once melted, turn off heat and drop in garlic and fresh herbs.  Set aside. 
  3. Slice sweet potatoes into thin slices with a mandolin and arrange upright on their sides in a 10 inch skillet.
  4. Brush garlic butter mixture over the sweet potatoes, pushing the brush between the slices to coat them. 
  5. Cover and bake for 40 minutes, until just tender.  Remove cover and turn heat up to 475’F.  Bake for another 10-15 minutes, or until edges start to brown a bit. Sprinkle top with a bit of salt. Enjoy!




If you don’t have a 10 inch skillet, this can be made in an 8×8 baking dish. 

I highly recommend slicing your sweet potatoes with a mandolin to get perfectly even slices. THIS is the mandolin I use.
