Step-by-step process (detailed)
1. Preheat and prepare
Preheat oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.
2. Mash the yams
Place drained canned yams in a large bowl. Mash until smooth using a potato masher or hand mixer.
3. Mix the base
Add melted butter, brown sugar, eggs, milk, vanilla, cinnamon, nutmeg, and salt. Mix thoroughly until creamy and well combined.
4. Transfer to baking dish
Spread the sweet potato mixture evenly into the prepared baking dish, smoothing the top.
5. Add topping
For marshmallows: sprinkle evenly over the top.
For pecan streusel: mix brown sugar, flour, melted butter, and pecans, then sprinkle evenly over the casserole.
6. Bake
Bake uncovered 25–30 minutes, until heated through and lightly set.
7. Brown the topping
If using marshmallows, switch oven to broil for 1–2 minutes, watching closely, until golden brown.
8. Rest and serve
Let the casserole rest 5–10 minutes before serving so it sets properly.
