For the Mashed Sweet Potatoes

  • 4 large sweet potatoes
  • ½ cup granulated sugar
  • 1 tsp kosher salt

Directions

  6. Add topping: Sprinkle streusel evenly over the baked potatoes and return to the oven for another 10–15 minutes until the crumble is lightly browned and crisp.
  7. Serve: Remove from oven and let set briefly, or cover with foil and serve within 30 minutes.

FAQs

1. How can I cook the sweet potatoes?

You can boil peeled wedges for 20 min, bake whole at 400 °F for 45–60 min, or microwave each potato (pierced) for 8–10 min until soft.

2. Can I prepare ahead of time?

Yes—assemble and refrigerate (without topping) up to a day ahead. Bake when ready and add streusel later.

3. Can I reduce sugar?

Yes—reduce granulated sugar to ¼ cup and brown sugar topping to ½ cup, or use a sugar substitute.

4. What’s the best nut for the topping?

Pecans add classic flavor and texture, but walnuts or chopped almonds work well too.

5. Can I make it dairy-free?

Use vegan butter alternatives and omit eggs, or replace with flax eggs.

6. Is this gluten-free?

With gluten-free flour or oat flour in the topping, and using certified GF ingredients, yes.

7. Can I double the recipe?

Yes—use a larger baking dish and adjust baking time slightly (about 5–10 extra minutes).

8. What if I don’t have an electric mixer?

Mash by hand or with a potato masher, then stir thoroughly to ensure smoothness.

9. Can I make it less sweet?

Omit sugar entirely or reduce it to suit savory preferences—add spices like cinnamon for balance.

10. Can I top with fresh herbs?

Optional: Garnish with fresh thyme or rosemary for a savory accent.
