Ingredients

For the Sweet Potato Base

  • 4 pounds (1.8 kg) sweet potatoes, peeled and cubed into 1-inch pieces

  • ⅓ cup (75g) unsalted butter, melted

  • ½ cup (120ml) pure maple syrup (preferably Grade A Dark)

  • 2 large eggs, room temperature

  • ¼ cup (60ml) heavy cream or whole milk

  • 1 teaspoon pure vanilla extract

  • 1 teaspoon ground cinnamon

  • ½ teaspoon ground nutmeg

  • ¼ teaspoon ground ginger

  • ¾ teaspoon kosher salt

For the Pecan Streusel Topping

  • 1 cup (120g) all-purpose flour

  • ¾ cup (150g) packed light brown sugar

  • ½ cup (115g) cold unsalted butter, cut into small cubes

  • 1½ cups (180g) pecans, roughly chopped

  • ¼ teaspoon kosher salt

Choose Grade A Dark maple syrup for robust flavor that won’t disappear during baking. Cold butter is essential for achieving a crumbly streusel texture rather than a greasy paste.

Pro Tips

Maple Syrup Selection: Grade A Dark (formerly Grade B) maple syrup provides the strongest maple flavor that stands up to baking and complements sweet potatoes beautifully. Avoid pancake syrups or artificial maple flavoring, which add chemical sweetness without depth. Real maple syrup contains natural minerals and complex sugars that caramelize during baking, creating layers of flavor impossible to replicate with substitutes.

Perfect Streusel Texture: Keep your butter ice-cold and work quickly when mixing the streusel topping. Use a pastry cutter, two forks, or pulse in a food processor just until the mixture resembles coarse crumbs with pea-sized butter pieces visible. Overmixing creates a dense, cookie-like topping instead of the crispy, crumbly texture you want. Refrigerate the prepared streusel for 15 minutes before sprinkling over the casserole to ensure it stays separate and crunchy.

Smooth Base Secrets: After boiling, spread sweet potatoes on a baking sheet for 5 minutes to allow steam to escape before mashing. This extra drying step prevents watery filling. For the smoothest Southern Maple Sweet Potato Casserole, use a food processor or immersion blender rather than a hand masher, which leaves fibrous strands. Beat the mixture until it looks glossy and completely homogeneous, about 2-3 minutes with an electric mixer.

Instructions

Step 1: Cook the Sweet Potatoes

Place cubed sweet potatoes in a large pot and cover with cold water by 2 inches. Add 1 teaspoon of salt to season the potatoes as they cook. Bring to a rolling boil over high heat, then reduce to medium-high and maintain a steady simmer for 15-20 minutes until the sweet potatoes are completely tender and fall apart when pierced with a fork. The largest pieces should offer no resistance. Drain thoroughly in a colander, then spread the sweet potatoes on a rimmed baking sheet in a single layer. Let them steam-dry for 5 minutes, allowing excess moisture to evaporate so your casserole won’t be soupy.

Step 2: Prepare the Sweet Potato Mixture

Preheat your oven to 350°F (175°C) and butter a 9×13-inch (23x33cm) baking dish generously. Transfer the dried sweet potatoes to a large mixing bowl or food processor. Add melted butter, maple syrup, eggs, heavy cream, vanilla extract, cinnamon, nutmeg, ginger, and salt. Using an electric mixer on medium-high speed or pulsing the food processor, blend for 2-3 minutes until the mixture becomes completely smooth, silky, and fluffy with no visible lumps or fibrous bits. The filling should look glossy and pour easily. Taste and adjust spices or maple syrup if you prefer bolder flavor—this is your opportunity to customize the sweetness level.

Step 3: Make the Pecan Streusel

In a medium bowl, combine flour, brown sugar, and salt. Add the cold butter cubes and use a pastry cutter or two forks to work the butter into the dry ingredients until the mixture resembles coarse breadcrumbs with pea-sized butter pieces throughout. You should still see distinct butter chunks—this creates the flaky, crispy texture. Fold in chopped pecans until evenly distributed. Place the streusel bowl in the refrigerator while you assemble the casserole base to keep the butter cold and prevent premature melting.

Step 4: Assemble the Casserole

Pour the sweet potato mixture into your prepared baking dish, using a spatula to spread it evenly to all corners and smooth the top surface completely flat. This even layer ensures uniform cooking and provides a level base for the streusel. Tap the dish gently on the counter 2-3 times to release any trapped air bubbles. Remove the chilled streusel from the refrigerator and sprinkle it evenly over the entire surface of the Southern Maple Sweet Potato Casserole, breaking up any large clumps with your fingers. Distribute the pecan pieces evenly so every serving gets plenty of crunchy topping.

Step 5: Bake to Golden Perfection

Place the casserole on the center oven rack and bake for 40-45 minutes until the streusel turns deep golden brown and the sweet potato filling bubbles gently around the edges. The topping should look crispy and toasted, with pecans releasing their aromatic oils. Insert a knife into the center—it should come out clean with no liquid sweet potato clinging to it. If the streusel browns too quickly before the filling sets, tent loosely with aluminum foil for the final 10-15 minutes of baking. Remove from the oven and let rest for 10-15 minutes before serving, allowing the filling to firm up slightly and making it easier to serve clean portions.

Variations

Bourbon-Spiked Version: Add 3 tablespoons of bourbon or whiskey to the sweet potato mixture along with the maple syrup for a grown-up twist with sophisticated depth. The alcohol cooks off during baking, leaving behind warm, oaky notes that complement the maple beautifully. Sprinkle the finished casserole with flaky sea salt for a sweet-salty contrast that enhances all the flavors.

Dairy-Free Adaptation: Replace butter with coconut oil (use refined for neutral flavor or virgin for subtle coconut notes) and substitute full-fat coconut cream for the heavy cream. Use dairy-free butter or additional coconut oil in the streusel topping. This version maintains the creamy texture and rich flavor while accommodating lactose-intolerant and vegan guests when you swap eggs for flax eggs (2 tablespoons ground flaxseed mixed with 6 tablespoons water, let sit 5 minutes).

Lighter Oat Crumble Topping: Replace half the flour in the streusel with old-fashioned rolled oats and reduce butter to ⅓ cup for a heartier, slightly healthier topping with more texture. Add ½ teaspoon of cinnamon to the streusel mixture and consider mixing in ¼ cup of unsweetened shredded coconut alongside the pecans for tropical flair that pairs surprisingly well with maple sweetness.

Storage and Serving

Store leftover Southern Maple Sweet Potato Casserole covered with aluminum foil or transferred to an airtight container in the refrigerator for up to 5 days. The streusel topping softens slightly during storage but maintains pleasant texture. Reheat individual portions in the microwave for 1-2 minutes, or warm the entire casserole covered at 325°F (165°C) for 20-25 minutes until heated through. For crispier topping, uncover for the final 5 minutes of reheating or place briefly under the broiler.

Serve this maple-glazed sweet potato casserole as a stunning centerpiece alongside roasted turkey, herb-crusted ham, or maple-glazed pork tenderloin for a cohesive flavor theme. The dish works beautifully for Thanksgiving, Christmas, or Sunday dinner gatherings. For elegant presentation, garnish with a drizzle of additional maple syrup and a sprinkle of toasted pecan halves just before bringing to the table. Consider pairing with tart cranberry sauce and savory green beans to balance the sweetness across your meal.

FAQs

Can I make this casserole ahead of time?
Yes, assemble the complete casserole with the streusel topping, cover tightly with plastic wrap and foil, and refrigerate for up to 24 hours. Remove from the refrigerator 30 minutes before baking to take the chill off, then bake as directed, adding 5-10 extra minutes to the cooking time since it starts cold.

What’s the difference between maple syrup grades?
Grade A Dark (formerly Grade B) has a more robust, intense maple flavor perfect for baking, while Grade A Golden is lighter and more delicate, better suited for pancakes. Both are pure maple syrup, but the darker grade won’t get lost among the other flavors in this Southern sweet potato bake.

Can I use canned sweet potatoes?
While fresh sweet potatoes provide superior flavor and texture, you can substitute three 29-ounce cans of drained sweet potatoes or yams. Skip the boiling step entirely and reduce the cream to 2 tablespoons since canned varieties contain more moisture. The texture won’t be quite as fluffy, but the maple flavor will still shine through.

Why is my streusel topping soggy?
Soggy streusel results from butter that’s too warm when mixed or a sweet potato base that’s too wet. Always use cold butter and work quickly when making streusel, and ensure your sweet potato filling isn’t runny before baking. Proper steam-drying after boiling prevents excess moisture from making toppings soggy.

Can I freeze this casserole?
Freeze the baked and cooled casserole wrapped tightly in plastic wrap and aluminum foil for up to 3 months. Thaw overnight in the refrigerator, then reheat covered at 325°F for 30-35 minutes. Alternatively, freeze just the unbaked sweet potato base (without streusel), add fresh streusel after thawing, and bake as directed for optimal texture.
