Prep & Cook Time

Prep Time: 70 minutes | Cook Time: 55 minutes | Total Time: ~2 hours 5 minutes (plus cooling) | Servings: 16

Ingredients

• 2 pie crusts (store-bought or homemade (see note**))
• 4 tbsp salted butter (melted)
• ⅔ cup dark brown sugar (packed)
• 1 cup salted butter (cut into cubes or slices)
• 3 lbs sweet potatoes (about 3 large sweet potatoes)
• ¾ cup light brown sugar (packed)
• ¾ cup granulated sugar
• 1 cup evaporated milk
• 4 tsp pure vanilla extract
• 3/4 tsp ground cinnamon
• 3/4 tsp ground nutmeg (freshly ground, if possible)
• 3 tbsp orange juice
• 2 tbsp all-purpose flour
• 3 large eggs (room temperature)

Instructions

1. Preheat & Prepare Crusts: Preheat oven to 400°F (200°C). Place two 9-inch pie dishes on a baking sheet. Place one pie crust in each dish. Use a fork to gently prick the bottom and sides all over. Brush the inside of each crust, including the rim, with the 4 tbsp of melted butter.
2. Make Brown Sugar Layer: In a small bowl, mix the ⅔ cup dark brown sugar and 2 tbsp all-purpose flour. Sprinkle this mixture evenly over the bottom of each buttered crust.
3. Brown the Butter: In a light-colored saucepan, melt the 1 cup of cubed butter over medium heat. Continue cooking, swirling often, until the butter foams, then turns a deep golden brown and smells nutty, about 5-8 minutes. Immediately pour into a heat-proof bowl to stop cooking. Set aside to cool slightly.
4. Cook Sweet Potatoes: While butter browns, peel and cube the sweet potatoes. Place in a large pot, cover with water, and bring to a boil. Cook until very tender, 15-20 minutes. Drain well.
5. Make Filling: Return drained sweet potatoes to the warm pot. Add the ¾ cup light brown sugar, ¾ cup granulated sugar, 3/4 tsp cinnamon, 3/4 tsp nutmeg, and 3 tbsp orange juice. Mash with a potato masher until completely smooth. Let cool for 10 minutes.
6. Combine: To the sweet potato mixture, whisk in the slightly cooled brown butter, 1 cup evaporated milk, 4 tsp vanilla extract, and the 3 room-temperature eggs until fully combined and smooth.
7. Bake: Divide the filling evenly between the two prepared pie crusts. Place the baking sheet with the pies in the oven. Bake at 400°F for 15 minutes, then reduce heat to 350°F (175°C) and bake for another 35-40 minutes, or until the edges are set and the center jiggles only slightly.
8. Cool Completely: Remove pies from oven and let cool on a wire rack for at least 4 hours before slicing to allow the filling to fully set.

Variations

• Single Deep-Dish Pie: Use one deep-dish pie pan and all the filling. Baking time may need to increase by 10-15 minutes.
• Gingersnap Crust: Swap the pie crust for a homemade crust made from crushed gingersnap cookies and butter for a spiced twist.
• Marshmallow Topping: After baking and cooling, top with mini marshmallows and broil for 1-2 minutes until golden and toasty.
• Chilled Serve: For a denser texture, chill the pie thoroughly before serving.

Tips for Success

• Use a light-colored saucepan to brown your butter so you can easily see the color change.
• Ensure your sweet potato mash is completely smooth and cooled slightly before adding the eggs to prevent them from cooking.
• Room temperature eggs incorporate more evenly into the filling, creating a smoother custard.
• Let the pie cool completely—this is non-negotiable for a clean slice and perfect texture.

Storage & Reheating

Store leftover pie, covered, in the refrigerator for up to 4 days. You can enjoy it cold, or reheat individual slices in a 300°F oven for 10-15 minutes until warmed through.

FAQ

Why two pies?

This recipe makes a generous amount of filling. Using two standard 9-inch pie pans ensures even baking and perfect results.

Can I use unsalted butter?

Yes, but you may want to add an extra pinch of salt to the filling to balance the sweetness.

Do I have to use evaporated milk?

Evaporated milk is recommended for its rich, creamy texture and stability. Heavy cream is the best substitute in a pinch.

My crust is browning too fast. What should I do?

If the crust edges brown too quickly, use pie shields or strips of aluminum foil to cover them for the remainder of the baking time.

Can I make this ahead?

Absolutely! Bake the pies, let them cool completely, and store covered in the fridge for 1-2 days before serving. This can even improve the flavor.

The center is still wobbly after baking. Is it done?

Yes, it should have a slight jiggle in the very center. It will continue to set as it cools on the counter.
