Potato Layer:

  • 2.5 pounds sweet potatoes peeled and cubed
  • 3 Tbsp milk cow, almond, goat, etc.
  • 2 Tbsp butter
  • 1 Tbsp brown sugar or maple syrup
  • 1/2 tsp salt

Oatmeal Pecan Crumble Layer:

  • 2/3 cup steel-cut oats
  • 1 Tbsp white whole wheat flour
  • 2/3 cup unsalted pecans chopped
  • 2 Tbsp. brown sugar
  • 1 tsp. ground cinnamon
  • 2 Tbsp. butter softened
  • pinch of salt


  • Peel and chop sweet potatoes into 1-inch thick cubes.  Add potatoes to a pot of cold water and bring to a boil.  Boil sweet potatoes until fork tender (approx. 25-30 minutes).
  • While potatoes are boiling, preheat oven to 375 degrees F and spray an oven-safe dish with cooking spray.  I used a 10" x 2" tart pan.
  • Meanwhile, in a small bowl, combine the oats, flour, chopped pecans, brown sugar, cinnamon and salt.  Add in your softened butter, using your hands to completely incorporate it with the dry ingredients.
  • Drain potatoes and add to a large bowl.  Add milk, butter, brown sugar (or maple syrup) and salt.  Using a potato masher, mash and mix the potatoes and other ingredients until smooth and combined.  Spread evenly into your prepared baking pan.
  • Finally, sprinkle your crumble mixture evenly over the top of the sweet potatoes.
  • Bake for 20-25 minutes, or until nuts and oats are golden brown.


this recipe is as simple as it gets.  You can whip your potatoes in a standing mixer until they are light and fluffy, however, I find it easier to simply mash it all together.  You can also save time by boiling your potatoes the day before and refrigerate them until you are ready to use them.
