Step‑by‑Step Instructions

Prepare the Sweet Potatoes
Place cubed sweet potatoes in a large pot, cover with cold water, and bring to a boil. Simmer 12‑15 minutes until fork‑tender. Drain well and return to pot.
Mash & Enrich
Add melted butter, heavy cream, cinnamon, nutmeg, and sea salt to the potatoes. Mash until smooth and fluffy; avoid over‑mixing to keep a light texture.
Assemble the Base
Transfer the mash into a greased 9‑x‑13‑inch baking dish, spreading evenly.
Prepare the Streusel
In a bowl combine brown sugar, maple syrup, chopped pecans, and a tablespoon of melted butter. Mix until crumbs form and the mixture clings together.
Bake & Serve
Sprinkle streusel evenly over the mash. Bake at 375°F for 20‑25 minutes, until topping is golden and bubbling. Let rest 5 minutes before slicing.
Expert Tips
Tip #1: Use Hot Cream
Warm the heavy cream before mixing; it blends smoothly and keeps the mash airy, preventing a gummy texture.
Tip #2: Chill the Dish
After assembling, refrigerate for 30 minutes before baking. The chilled base helps the topping stay crisp.
Tip #3: Add a Pinch of Cayenne
A tiny dash of cayenne in the mash brightens the sweet flavors without overwhelming heat.
Tip #4: Serve Warm
This casserole shines at 70‑75°F. Reheat gently in a low oven to retain the crunchy topping.
Storage & Variations
Store leftovers in an airtight container in the refrigerator for up to 4 days; reheat covered at 325°F until warmed through. For a vegan twist, replace butter with coconut oil and cream with oat milk, and use maple‑sweetened coconut sugar in the streusel. Add dried cranberries to the topping for a festive burst of tartness.
