Instructions

SWEET POTATO FILLING

Add potatoes to a Dutch oven and add just enough water to cover potatoes. Season with 1/2 teaspoon salt. Bring to a boil then reduce heat and simmer 10-15 minutes or until very tender when pierced with a fork; drain VERY WELL.
Preheat oven to 350 degrees F.
Add potatoes to large bowl (to use with hand held mixer). Add all “Casserole” ingredients except eggs and beat until combined.
Add eggs; beat well, but don’t beat out all the lumps. You don’t want it to be perfectly smooth.
Pour potato mixture into a 13 x 9–inch baking pan coated with cooking spray.

BROWN SUGAR PECAN TOPPING**

Add pecans, maple syrup and vanilla extract to food processor. Pulse 3 times to slightly chop up pecans. Add all remaining topping ingredients and pulse until it resembles coarse pebbles. (See notes if you don’t have a food processor.)
Evenly spread Brown Sugar Pecan Topping over potatoes and bake at 350 degrees F for 30 minutes or until golden.

MARSHMALLOWS

Remove casserole and line top with marshmallows (you won’t use the whole bag). Bake an additional 5-10 minutes (closer to 10 minutes for extra gooey marshmallows that spread together, my personal preference) then broil marshmallows until golden brown, watching carefully so they don't burn.

MAKE AHEAD

Make casserole as directed through spreading sweet potatoes in baking pan. Let sweet potatoes cool completely, cover and refrigerate for up to 3 days.
Meanwhile, prepare Brown Sugar Pecan Topping as directed and store in a sealed container or plastic bag in the refrigerator.
When ready to bake, remove potatoes and topping from the refrigerator at the same time. Uncover potatoes and bake at 350 degrees for 20 minutes. Add topping and continue to bake an additional 30 minutes OR until potatoes are completely warmed through. Add marshmallows and bake as directed, 5-10 minutes.
