Streuseled Sweet Potato Casserole: A Thanksgiving Tradition Reimagined

The aroma of sweet potatoes roasting is practically synonymous with Thanksgiving in my mind. As a child, I remember my grandmother, a woman who ruled the kitchen with a gentle hand and an iron will, always made a sweet potato casserole. It wasn’t the marshmallow-laden kind; her version was far more sophisticated, nuanced with spices and a hint of citrus. The warm, earthy sweetness filling the air, mingling with the crisp scent of autumn leaves outside – that’s what Thanksgiving smelled like. This streuseled sweet potato casserole honors her memory, while offering a welcome twist on a beloved classic.

Recipe Overview

• Prep Time: 45 minutes
• Cook Time: 1 hour 45 minutes
• Total Time: 2 hours 30 minutes
• Servings: 10-15
• Yield: One 9×13 inch casserole
• Dietary Type: Vegetarian

Ingredients

• 7 lbs sweet potatoes (6 to 8 medium)
• 5 tablespoons unsalted butter, cut into pieces and softened, plus additional for greasing pan
• 1/2 cup all-purpose flour
• 1/2 cup packed brown sugar
• 2 1/4 teaspoons salt, divided
• 1 cup pecans
• 5 tablespoons unsalted butter, melted
• 1/2 teaspoon ground nutmeg
• 1/2 teaspoon ground black pepper
• 1 tablespoon vanilla extract
• 4 teaspoons fresh lemon juice
• Granulated sugar, to taste (up to 4 Tbsp)
• 4 large egg yolks
• 1 1/2 cups half-and-half

Equipment Needed

• Baking sheet
• Aluminum foil
• 9-by-13-inch baking dish
• Food processor
• Large bowl
• Medium bowl
• Rubber spatula

Instructions

1. Prepare the sweet potatoes: Preheat your oven to 400 degrees Fahrenheit. Poke each of the sweet potatoes several times with a knife. Arrange them evenly on a baking sheet lined with aluminum foil.
2. Bake the sweet potatoes: Bake the sweet potatoes, turning them once halfway through, until they are very tender and easily squeezed with tongs. This should take between 1 hour and 1 hour 30 minutes.
3. Cool the sweet potatoes: Remove the potatoes from the oven and cut them in half lengthwise to allow the steam to escape. Let them cool for at least 10 minutes.
4. Scoop the potato flesh: Once the sweet potatoes are cool enough to handle, scrape the flesh away from the skins into a large bowl. You should have approximately 8 cups of sweet potato flesh. At this point, you can cool the flesh to room temperature, and refrigerate it if you’re making this ahead of time.
5. Prepare the streusel topping: Butter a 9-by-13-inch baking dish.
6. Combine dry streusel ingredients: In a food processor, pulse the flour, brown sugar, and 1/4 teaspoon of salt until well blended.
7. Incorporate the butter: Sprinkle the butter pieces over the flour mixture and pulse until a crumbly mass forms, about 6 to 8 one-second pulses.
8. Add the pecans: Sprinkle the pecans over the mixture and pulse until combined, but some large nut pieces remain, about 4 to 6 one-second pulses.
9. Transfer the streusel: Transfer the streusel to a medium bowl and return the work bowl to the food processor.
10. Prepare the sweet potato filling (part 1): Place half of the sweet potato flesh into the food processor. With a rubber spatula, break the remaining flesh in the bowl into 1-inch chunks.
11. Prepare the sweet potato filling (part 2): Add the melted butter, 2 teaspoons of salt, nutmeg, pepper, vanilla, and lemon juice to the potatoes in the food processor. Process until smooth, about 20 seconds.
12. Sweeten to taste: Taste the mixture for sweetness, and add up to 4 tablespoons of granulated sugar if desired, processing briefly to incorporate.
13. Add the egg yolks: Add the egg yolks and process for about 15 seconds.
14. Incorporate the half-and-half: With the processor running, pour the half-and-half through the feed tube and process until blended, about 30 seconds.
15. Combine the mixtures: Transfer the puréed sweet potato mixture to the large bowl with the sweet potato chunks. Stir gently until combined.
16. Assemble the casserole: Pour the sweet potato filling into the prepared baking dish and spread evenly with a spatula. Sprinkle the streusel over the top, breaking up any large pieces with your fingers.
17. Bake the casserole: Bake until the topping is well browned and the filling is puffy around the edges, about 45 minutes.
18. Cool and serve: Cool slightly before serving. Alternatively, you can cool to room temperature, then cover and refrigerate. To reheat, bake at 400 degrees Fahrenheit for about 25 minutes.

Expert Tips & Tricks

• Baking the potatoes a day ahead is a great time-saver, especially during the holiday rush. Just be sure to let them cool completely before refrigerating.
• Don’t over-process the streusel. You want some texture from the pecans, so avoid pulverizing them into a paste.
• Adjust the sweetness to your liking. Start with a tablespoon or two of granulated sugar, taste, and add more if needed. Remember that the brown sugar in the streusel also contributes to the overall sweetness.
• If the streusel starts to brown too quickly during baking, tent the casserole dish loosely with foil.
• For a richer flavor, try using brown butter in the streusel. Simply melt the butter in a saucepan over medium heat, swirling occasionally, until it turns golden brown and smells nutty. Let it cool slightly before using.

Serving & Storage Suggestions

Serve this streuseled sweet potato casserole warm as a side dish alongside your favorite Thanksgiving or holiday meal. It pairs exceptionally well with roasted turkey, ham, or even a vegetarian main course like a nut roast.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, bake in a preheated oven at 350 degrees Fahrenheit until warmed through, or microwave individual portions.

While freezing is possible, it can slightly alter the texture of the sweet potato filling. If freezing, wrap the casserole tightly in plastic wrap and then foil. Thaw overnight in the refrigerator before reheating.
