‍ Creating Your Holiday Masterpiece: Step-by-Step

Step 1: Prepare Your Sweet Potatoes

Oven Method (Recommended for Best Flavor):
Preheat oven to 400°F (200°C). Pierce sweet potatoes with a fork, bake for 45-60 minutes until tender. Scoop out flesh.

Quick Boil Method:
Peel and cube sweet potatoes, boil until fork-tender (15-20 minutes). Drain well.

Step 2: Create the Creamy Base

Reduce oven temperature to 350°F (175°C). Grease a 9×13 inch baking dish.
In a large bowl, combine mashed sweet potatoes, granulated sugar, brown sugar, eggs, melted butter, milk, vanilla, cinnamon, nutmeg, and salt. Mix until smooth and well-combined.
Spread evenly into your prepared baking dish.

Step 3: Make the Pecan Streusel

In a medium bowl, combine brown sugar, flour, chopped pecans, and optional cinnamon. Add cold cubed butter.
Using a pastry cutter, two forks, or your fingers, work the butter into the dry ingredients until the mixture resembles coarse crumbs with some pea-sized butter pieces remaining.

Step 4: Assemble and Bake

Sprinkle the pecan streusel evenly over the sweet potato base.
Bake for 30-35 minutes, until the topping is golden brown and the filling is bubbly around the edges.
For extra crunch, broil for the final 1-2 minutes—watch closely to prevent burning!

Step 5: The Perfect Rest

Let the casserole cool for 15-20 minutes before serving. This allows the filling to set for perfect scooping.

5 Pro-Tips for Casserole Excellence
ROAST, DON’T BOIL: Roasting sweet potatoes caramelizes their natural sugars, creating deeper, richer flavor

DRAIN WELL: If boiling, drain potatoes thoroughly and return to warm pot to evaporate excess moisture

TOAST YOUR PECANS: Spread pecans on a baking sheet and toast at 350°F for 6-8 minutes before chopping for maximum flavor

DON’T SKIP THE EGGS: They provide structure and help create the perfect creamy-yet-firm texture

USE COLD BUTTER: For the best streusel texture, your butter must be cold straight from the refrigerator

Make-Ahead & Storage Tips
1 DAY AHEAD: Assemble completely, cover, and refrigerate. Add 5-10 minutes to baking time.

FREEZE UNBAKED: Wrap tightly and freeze for up to 3 months. Thaw in refrigerator before baking.

LEFTOVERS: Store covered in refrigerator for up to 4 days. Reheat in oven for best texture.
