Instructions

  • Preheat oven to 350 degrees F.
  • In a medium pot, add in quartered sweet potatoes and cover with cold water. Over high heat, bring to a boil, then lower the heat to medium (gentle boil). Cook potatoes till they are easily pierced with a fork (about 10-15 minutes). Drain and return to pot.
  • Add in 3 tbsp butter and mash the sweet potatoes [see note]. Add in the cinnamon, nutmeg, brown sugar, kosher salt, and slowly incorporate the half in half until fully combined. Taste and adjust seasoning if necessary. In a greased baking dish (I used a pie dish), add the mashed sweet potatoes.
  • Place in oven and bake uncovered for 20 minutes.
  • When there is 5 minutes left of the casserole baking, in a small bowl combine the crunchy topping ingredients [see notes]. Remove the casserole from the oven, spread the crunchy topping evenly over the sweet potatoes, and bake for an additional 10 minutes.
  • Remove from oven and serve immediately.

Notes

Sweet Potato Casserole Notes/FAQ's

  • Cooking sweet potatoes you can oven roast them (takes much longer) or boil them (quicker & method used in recipe)
  • Bring your potatoes to a boil in a pot of cold water to ensure even cooking
  • If preparing in advance, stop after making the mashed sweet potatoes and store in fridge for 3-5 days. Or you can freeze a week ahead and thaw overnight in the refrigerator prior to baking.
  • Do not prepare topping in advance, butter will cause cornflakes to get soggy
