• 1 tbsp unsalted butter or cooking spray, for the pan

Brown-Sugar Butter (for coating)

• 6 tbsp (85 g) unsalted butter, melted

• 1/2 tsp ground ginger
• 1/4 tsp ground nutmeg

• 3/4 cup (85 g) chopped pecans

Cream-Cheese Drizzle

• 3 oz (85 g) cream cheese, softened
• 1/2 cup (60 g) confectioners’ sugar

Step-by-Step Instructions

Step 1: Preheat and prepare the pan

Preheat the oven to 375°F (190°C) with a rack in the center. Butter a 9-inch round baking dish, pie plate, or a 10-inch oven-safe skillet (cast iron works beautifully). For super-clean release, you can line the bottom with a parchment circle.

Step 2: Slice the sweet potatoes

Peel the sweet potatoes and slice them into even 1/8-inch (3 mm) rounds, ideally with a mandoline for uniform thickness. Keep the slices stacked and nearby—uniform slices bake evenly and create a neat spiral. If you prepped slices ahead in cold water, drain and pat them very dry before continuing.

Step 3: Make the brown-sugar butter

In a medium bowl, whisk together the melted butter, dark brown sugar, cinnamon, ginger, nutmeg, fine sea salt, vanilla, and orange zest (if using). The mixture should be glossy and spoonable; if it thickens, warm it for 10–15 seconds to loosen.

Step 4: Coat and spiral the slices

Reserve 3 tablespoons of the brown-sugar butter. Add the sweet-potato slices to the remaining mixture and toss gently to coat. Start from the center of the prepared pan and stand the slices on their edges, overlapping tightly in a spiral (like a giant cinnamon roll). Tuck in smaller slices as you reach the edges. Spoon any residual mixture from the bowl over the top, then brush with the reserved 3 tablespoons for even coverage.

Step 5: Steam-bake to soften

Tent the dish tightly with foil so steam is trapped. Bake for 25 minutes. This step softens the potatoes so they finish tender without drying out.

Step 6: Add pecans and caramelize

Remove the foil and scatter the chopped pecans evenly over the top, nudging some into the crevices. Return to the oven and bake uncovered for 20–25 minutes, rotating once, until the potatoes are fork-tender and the edges are deeply caramelized and glossy. For extra toasty edges, broil on high for 1–2 minutes—watch closely.

Step 7: Mix the drizzle and finish

While the casserole finishes, whisk the cream cheese, confectioners’ sugar, 2 tablespoons milk, vanilla, and a pinch of salt until smooth and pourable; add the remaining milk if needed. Let the casserole rest 10 minutes, then drizzle in loose zigzags. Finish with a pinch of flaky sea salt and a little extra orange zest, if you like. Serve warm.

Pro Tips

• For the prettiest spiral, sort slices by size and start with the largest at the center, working outward to smaller pieces.
• A mandoline set to 1/8 inch (3 mm) ensures even cooking and tidy layers; use a cut-resistant glove for safety.
• Place the baking dish on a rimmed sheet pan to catch any buttery drips.
• Room-temperature cream cheese makes a silky, lump-free drizzle in seconds.
• If your oven runs hot, reduce to 365°F (185°C) for the uncovered portion to prevent over-browning.

Variations

• Maple-Walnut: Replace half the brown sugar with 1/4 cup pure maple syrup and swap pecans for walnuts.
• Chai Spice: Use 1 tsp cinnamon, 1/2 tsp cardamom, 1/4 tsp ginger, 1/8 tsp cloves for a chai-like profile.
• Savory-Sweet: Skip the drizzle; add 1/4 tsp smoked paprika and 1/8 tsp cayenne to the butter mixture and finish with toasted pepitas.

Storage & Make-Ahead

Assemble up to 12 hours ahead: arrange the spiral, cover tightly, and refrigerate. Bake straight from the fridge, adding 5–10 minutes to the covered bake. Leftovers keep 4 days in an airtight container in the fridge; reheat at 325°F (165°C) for 10–15 minutes. Freeze the baked (undrizzled) casserole up to 2 months; thaw overnight in the fridge, warm at 325°F (165°C), then add the fresh drizzle before serving.
