How to make this pretty sweet potato casserole recipe

Even though this casserole looks impressive, it's quite simple to make. The one tool that will really help you here is a mandolin. It makes quick work of slicing the sweet potatoes and ensures that each slice is uniform. This is the mandolin that we have. While there are better quality ones available, this one is inexpensive and does the trick.

We leave the skin on the sweet potatoes. It's less work that way. If your sweet potatoes are looking a little rough or you know you don't like the skin, you can always peel it.

  1. Slice the sweet potatoes using a mandoline.
  2. Toss the slices with some oil, salt, and a little cayenne then arrange them in a casserole dish and pour some maple syrup over the top.
  3. Cover the casserole and pop it into your oven. After a half-hour, uncover it and keep on baking.
  4. Now stovetop toast some pecans in a little butter then add lots of pepper.
  5. Broil the casserole briefly so it gets a little crispy then sprinkle the pecans over the top.

Done! If needed, you can arrange the casserole and make the pecans ahead of time.

Ingredients

  • 4 lbs sweet potatoes, sliced ⅛ inch thick
  • 3 tablespoons avocado oil
  • 1 teaspoon salt
  • ¼ teaspoon cayenne
  • 3 tablespoons maple syrup
  • 1 cup pecans

    4 lbs sweet potatoes
  • Add the avocado oil, salt, and cayenne to the bowl and carefully mix the sweet potatoes.
    3 tablespoons avocado oil, 1 teaspoon salt, ¼ teaspoon cayenne
  • Add the sweet potatoes to your casserole dish so that they stand on end – see picture. Cover the casserole dish with a lid or foil and bake for 30 minutes.
  • Take the casserole out of the oven and remove the foil or lid. Pour the maple syrup over the top and put it back into your oven, uncovered, for 40 minutes.
    3 tablespoons maple syrup
  • While the casserole is baking, make the peppery pecans. Heat the butter in a large frying pan over medium-high heat. Add the pecans and let them toast until they begin to smell fragrant, about 4-5 minutes. Remove them from the heat and stir in the pepper.
    1 cup pecans, 1 tablespoon butter, 1 teaspoon pepper
  • Turn your oven to broil (see notes) and broil the casserole for 5-10 minutes, or until the top starts to brown. Remove the casserole from the oven and sprinkle the pecans over the top.

Notes

If you can't control the temperature your oven broils at, keep an extra close eye to make sure it doesn't burn. A few very dark spots are ok but you don't want too many.
