This sweet potato casserole is an impressive, easy side dish ideal for your Thanksgiving or Christmas holiday dinners. The sweet potatoes are shingled (sliced thinly), then stacked in a casserole dish with a bit of maple syrup poured over the top. Once they're soft and slightly crispy at the edges, sprinkle with peppery pecans and serve.
Preheat your oven to 400 degrees Fahrenheit. Grease a 9x13-inch casserole dish with oil. Cut the sweet potatoes, preferably with a mandoline, and place them in a large bowl.
3 lb sweet potatoes
Add the avocado oil, salt, cinnamon, cloves, and cayenne to the bowl and carefully mix the sweet potatoes.
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.
¼ cup maple syrup
While the casserole is baking, make the peppery pecans. Heat the butter in a medium frying pan over medium-high heat. Add the pecans and let them toast until they begin to darken and smell fragrant, about 4-5 minutes. Add the sage and garlic and let them cook for 30 seconds. Remove them from the heat and stir in the pepper.
Turn your oven to broil (see notes) and broil the casserole for about 5 minutes, or until the top starts to brown. Remove the casserole from the oven and pour the buttery pecans over the top.
Notes
If you can't control the broil temperature on your oven, keep a close eye on it to ensure it doesn't burn.
