Ingredients
Sweet Potato Base
29ozcanned yams in syrup(not drained)
¼cupsalted butter(melted)
½cuphalf and half
2large eggs
1teaspooncinnamon
1teaspoonnutmeg
Brown Sugar and Pecan Topping
¼cupsalted buttermelted
1cuplight brown sugar
½cupcrushed pecans
½cupall-purpose flour
1teaspooncinnamon
Instructions
Preheat oven to 350 degrees.
In a large bowl, lightly mash the 29oz of canned yams. Add ¼ cup melted butter, ½ cup half and half, 2 eggs, 1 teaspoon cinnamon, and 1 teaspoon nutmeg. Stir well.
Pour mixture in a greased 8x8" glass baking dish.
In a separate bowl, use a fork to mix ¼ cup melted butter, 1 cup brown sugar, ½ cup crushed pecans, ½ cup flour, and 1 teaspoon cinnamon. Sprinkle this mixture over the sweet potatoes in the baking dish.
Bake for 35-40 minutes at 350° until brown sugar and pecan topping starts to turn golden brown.
Notes
Don’t drain the canned yams - the syrup adds sweetness and moisture. For a less-sweet casserole, pour off half before mashing.
Use an 8x8-inch dish for one 29 oz can. Double everything for a 9x13 pan and bake 45–50 minutes.
The mixture will look thin before baking - it thickens as it cooks and sets while cooling.
For extra crunch, toast pecans before mixing into the topping.
Prefer marshmallows? Top with about 3 cups mini marshmallows and broil 2–3 minutes after baking.
To make ahead, prep the base a day in advance and refrigerate. Add topping just before baking.
Freezer option: assemble the base in a foil pan, wrap well, and freeze up to 3 months. Thaw overnight, add topping, and bake as directed.
Avoid over-mixing the sweet potato base - leave a little texture for the best flavor.
