About the ingredients
Method
- Heat a 5 to 6-quart heavy-bottomed saucepan over medium-high. Add cubed sweet potatoes and enough water to cover them by about an inch.
- Cover and steam until potatoes are fork tender. This usually means poking with a fork until it slides through easily, around 15-18 minutes. Drain well, return potatoes to the saucepan to absorb residual heat and evaporate excess moisture for 1-2 minutes.
- While potatoes drain, preheat oven to 355 F. Grease a 9x13 baking dish lightly with nonstick spray.
- Add brown sugar, softened butter, vanilla extract, cinnamon, and grated ginger to the saucepan with hot potatoes. Use a potato masher to mash everything together. No blender or mixer; you want some texture but no large chunks. If too dry, splash a bit of milk or cream, but don't overdo it or it gets runny.
- Fold in half a cup of chopped pecans for crunchy pockets throughout. Patience here; folding preserves nut integrity versus stirring.
- Spread the mash evenly into the prepared dish, pressing lightly to level out. This makes a nice even cook and crisp edges.
- Evenly scatter the remaining chopped pecans on top, then cover with a generous mound of mini marshmallows.
- Bake uncovered around 27 minutes until the marshmallows are puffed, golden with some toasted spots. You want that scent of toasted sugar and buttery nuts filling the kitchen. Watch closely last 5 minutes to avoid burning marshmallows.
- Serve hot straight from the oven. The top is crisp and gooey, the inside tender and sweet with a touch of spice and crunch.
Cooking tips
Chef's notes
- 💡 Start potatoes in cold water, this avoids uneven cooking & ugly lumps later. Drain thoroughly but keep pan on heat for a minute or two for steam evaporation; helps avoid watery mash. Timing each step by feel not just clock saves texture.
- 💡 Use freshly grated ginger instead of nutmeg; the zing cuts sweetness sharply. Stir in ginger with cinnamon & vanilla while potatoes still hot so flavors meld well but don’t overpower. Be cautious with amount; ginger too much masks everything else.
- 💡 Brown sugar gives deeper caramel notes; maple syrup or coconut sugar swap easily but adjust quantity as liquids differ. Butter must be softened not melted to keep mash creamy but slightly firm; it traps air and creates body without runniness.
- 💡 Fold nuts gently, do not overmix or pecans crush into mush. Half in the mash, half on top keeps crunchy contrast. Toast nuts lightly before adding if you want extra aroma; raw nuts can feel dull once baked under marshmallows.
- 💡 Watch marshmallows closely last 5 minutes; puffed and golden with little toasted spots is the cue. Too dark means bitter burnt sugars. Oven temps vary - use visual cues over timer. Let dish rest briefly post bake to set edges; avoids marshmallow tearing when served.
Common questions
How to know potatoes are done?
Fork test only. Should slide easily. Check around 15 minutes. Don’t trust timer alone. Soft but not falling apart. If tough, steam longer. Don’t rush or lumps form.
What else besides pecans works?
Walnuts or sliced almonds are fine alternatives. Pumpkin seeds if avoiding nuts totally. Toast these first for flavor. Can skip nuts but expect less crunch. Mix nuts wisely with folding, not stirring hard.
My bake turned watery, why?
Probably didn’t drain or steam potatoes enough. Water content high. Return potatoes to pan after draining to evaporate residual moisture a few minutes. If mash runs, add more butter or brown sugar, no milk until texture settled.
Can leftovers be stored?
Use airtight container fridge up to 4 days. Reheat gently in oven so marshmallow top softens again. Freeze not ideal due to marshmallows changing texture. If frozen, thaw slow overnight in fridge before reheating.
