Prep
  1. Preheat oven to 375°F.

  3. Place on a parchment-lined sheet pan.
  4. Bake for 45 minutes to 1 hour until completely soft when pierced with a knife.
  5. Let cool enough to handle.
  6. Cut the sweet potatoes in half and scoop out the flesh into a mixing bowl.
  7. Discard the skins.

Notes

This casserole works best when assembled ahead—the flavors meld and the make-ahead approach removes stress from holiday cooking timelines. Toast the pecans in the melted butter to develop deeper flavor before mixing with the streusel topping. If the marshmallows brown too quickly, tent loosely with foil for the final 10 minutes. You can substitute canned sweet potato puree to save time, but roasting whole sweet potatoes gives better texture and flavor control. Leftovers reheat well covered at 325°F for 15-20 minutes, though the topping won't be as crisp. The dish can go straight from refrigerator to oven; just add 5-10 minutes to the bake time.
