🥗 Ingredients

The Sweet Potato Base

  • 4 pounds Sweet Potatoes (peeled and cut into 1-inch cubes)
  • 1/2 cup Unsalted Butter (melted and slightly browned)
  • 1/4 cup Whole Milk (at room temperature)
  • 1/4 cup Maple Syrup (Grade A dark preferred)
  • 2 Eggs (large, lightly beaten)
  • 1 tablespoon Bourbon (optional, for depth of flavor)
  • 1 teaspoon Vanilla Extract (pure Madagascar vanilla)
  • 1 teaspoon Kosher Salt
  • 1/2 teaspoon Ground Cinnamon
  • 1/4 teaspoon Ground Nutmeg (freshly grated if possible)

The Pecan Streusel Topping

  • 1 1/2 cups Pecans (roughly chopped)
  • 1/2 cup Light Brown Sugar (packed)
  • 1/3 cup All-Purpose Flour
  • 4 tablespoons Unsalted Butter (chilled and cubed)
  • 1/2 teaspoon Flaky Sea Salt (for finishing)

👨‍🍳 Instructions

  1. 1

    Preheat your oven to 375°F (190°C). Grease a 9x13 inch ceramic baking dish with a light coating of butter or non-stick spray.

  2. 2

    Place the cubed sweet potatoes in a large pot and cover with cold water. Bring to a boil over high heat, then reduce to a simmer and cook for 15-20 minutes until fork-tender.

  3. 3

    While the potatoes boil, prepare the streusel. In a medium bowl, combine the chopped pecans, brown sugar, and flour. Use your fingers or a pastry cutter to work the chilled cubed butter into the mixture until it forms pea-sized clumps.

  4. 4

    Drain the cooked sweet potatoes thoroughly in a colander. Let them steam for 2-3 minutes to ensure excess moisture evaporates, which prevents a runny casserole.

  5. 5

    Transfer the warm potatoes to a large mixing bowl. Use a potato masher or an electric hand mixer on low speed to break them down until mostly smooth.

  6. 6

    In a small saucepan, melt the 1/2 cup of butter over medium heat, swirling until it smells nutty and shows small brown flecks. Pour this brown butter into the potatoes.

  7. 7

    Add the milk, maple syrup, bourbon, vanilla, salt, cinnamon, and nutmeg to the potato mixture. Whisk or beat until fully incorporated and light.

  8. 8

    Taste the mixture (before adding eggs!) to adjust seasoning. Once satisfied, fold in the beaten eggs until the batter is silky and uniform.

  9. 9

    Spread the sweet potato mixture evenly into the prepared baking dish, smoothing the top with a spatula.

  10. 10

    Sprinkle the pecan streusel mixture generously over the entire surface, ensuring even coverage from edge to edge.

  11. 11

    Bake for 25-30 minutes. The edges should be bubbling slightly, and the pecan topping should be a deep golden brown and fragrant.

  12. 12

    Remove from the oven and immediately sprinkle with a pinch of flaky sea salt to balance the sweetness. Let the casserole rest for 10 minutes before serving to allow the base to set.

💡 Chef's Tips

For the smoothest texture, pass the boiled potatoes through a potato ricer before mixing. Avoid over-boiling the potatoes; if they absorb too much water, the casserole will be soggy. If you prefer a boozeless version, substitute the bourbon with an equal amount of orange juice for a bright citrus note. Make-ahead tip: You can prepare the potato base and the topping separately up to 24 hours in advance; just store them in the fridge and assemble right before baking. Check the topping halfway through baking; if the pecans are browning too fast, tent the dish loosely with aluminum foil.

🍽️ Serving Suggestions

Serve alongside a herb-roasted turkey or honey-glazed ham for a traditional holiday feast. Pairs beautifully with a crisp, dry Riesling or a glass of spiced apple cider. Add a side of sautéed garlicky kale or roasted Brussels sprouts to cut through the richness. For a decadent touch, serve with a small dollop of crème fraîche on the side. Leftovers are incredible when reheated and served with a scoop of vanilla bean ice cream as a rustic dessert.
