Expert Tips

1. Don’t overboil the potatoes: Too much water can make the filling runny.

2. Use room-temperature ingredients: Butter and eggs mix better when not cold.

3. Cut butter cold for topping: Cold butter ensures a crumbly, crispy streusel.

4. Choose the right dish: A shallow baking dish gives more surface area for that golden topping.

5. Let it rest: 10 minutes of cooling helps the flavors meld and topping crisp up further.

Storage and Reheating

• Refrigerate: Store leftovers covered for up to 4 days.

• Reheat: Warm in a 350°F oven for 10–15 minutes to crisp the topping again.

• Microwave: Works for quick reheats, but topping may soften slightly.

FAQs

Can I use canned sweet potatoes?
Yes, but drain them well and reduce sugar slightly since canned versions are often sweetened.

How do I prevent the topping from sinking?
Make sure your streusel has enough flour and cold butter — that’s what keeps it crumbly.

Can I double this recipe for a crowd?
Absolutely! Use a large roasting pan and increase bake time by 10 minutes.

Is this dish gluten-free?
Use a gluten-free flour blend for the topping, and it will be fully gluten-free.

Can I make it without eggs?
Yes — substitute 2 tablespoons of cornstarch mixed with 2 tablespoons of water to bind the filling.

The Secret to the Perfect Streusel

The key to a crisp, golden streusel is using cold butter and even-sized pecan pieces. When baked, the butter melts slowly, allowing the sugar and flour to caramelize around the nuts — creating that irresistible crunch.

For an extra golden finish, sprinkle a light dusting of coarse sugar before baking.
