Ingredients
- 3 pounds fresh sweet potatoes (about 6-8 medium potatoes)
- 6 tablespoons unsalted butter, divided
- 1/2 cup whole milk
- 1/4 cup heavy cream
- 1/2 cup granulated sugar
- 1 teaspoon vanilla extract
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg
- 1/4 teaspoon ground ginger
- 1/8 teaspoon ground cloves
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 2 large eggs, room temperature
- 1 cup chopped pecans
- 3/4 cup brown sugar, packed
- 1/2 cup all-purpose flour
- 1/4 teaspoon salt (for topping)
- 3 tablespoons cold unsalted butter (for topping)
Instructions
- Preheat your oven to 350°F. Wash the sweet potatoes thoroughly under running water and pierce each one several times with a fork to allow steam to escape during cooking.
- Place the prepared sweet potatoes directly on the oven rack with a baking sheet positioned on the lower rack to catch any drips. Bake for 40-50 minutes, until the sweet potatoes are completely tender when pierced with a fork.
- Remove the sweet potatoes from the oven and allow them to cool for 10 minutes until they’re safe to handle but still warm, as this makes peeling much easier.
- Once cooled slightly, carefully cut each sweet potato in half and scoop the soft flesh into a large mixing bowl, discarding the skins. You should have approximately 3 cups of cooked sweet potato flesh.
- Using an electric mixer or by hand with a sturdy wooden spoon, mash the warm sweet potatoes until they’re relatively smooth but still contain a few small lumps for texture.
- Add 4 tablespoons of the butter to the warm sweet potatoes and mix until completely melted and incorporated throughout.
- In a small bowl, whisk together the milk, heavy cream, granulated sugar, vanilla extract, cinnamon, nutmeg, ginger, cloves, salt, and black pepper until well combined.
- Pour the milk mixture into the sweet potato mixture and stir until everything is evenly combined and smooth.
- In a separate small bowl, beat the room-temperature eggs with a fork until they’re well combined and slightly frothy.
- Slowly add the beaten eggs to the sweet potato mixture while stirring constantly to prevent the eggs from cooking. Mix until everything is fully incorporated and the mixture is creamy and smooth.
- Pour the sweet potato mixture into a buttered 9×13-inch baking dish, using a rubber spatula to spread it evenly into an even layer.
- In a medium bowl, combine the chopped pecans, brown sugar, flour, and salt for the topping. Mix these dry ingredients together thoroughly.
- Cut the 3 tablespoons of cold butter into small cubes and add to the pecan mixture. Using your fingertips, work the butter into the pecan mixture until it resembles coarse breadcrumbs with pea-sized pieces of butter throughout.
- Sprinkle the pecan streusel topping evenly over the sweet potato layer, pressing down gently so it adheres to the surface but doesn’t compact too much.
- Bake at 350°F for 30-35 minutes, until the topping is golden brown and the edges of the casserole are bubbling slightly around the sides.
- Remove from the oven and allow the casserole to rest for 5-10 minutes before serving, which allows it to set slightly and makes for easier portioning.
- Serve the casserole warm, either on its own or with a drizzle of bourbon sauce or a dollop of whipped cream for extra indulgence.
Pro Tips
For make-ahead preparation, you can assemble the casserole completely up to 24 hours in advance. Cover it tightly with plastic wrap and refrigerate. When ready to bake, add approximately 10-15 minutes to the baking time since you’ll be baking from a cold state.
The key to the perfect texture is achieving a balance between smooth and slightly lumpy in the base. Over-mixing creates a dense, gluey consistency, while under-mixing leaves unpleasant chunks. Aim for the consistency of soft mashed potatoes.
Room-temperature eggs are crucial for this recipe because they incorporate more smoothly into the warm sweet potato mixture without creating scrambled bits. Remove eggs from the refrigerator 30 minutes before starting if possible.
If you prefer a less sweet casserole, reduce the granulated sugar to 1/3 cup and the brown sugar to 1/2 cup. Conversely, if you like it sweeter, add an extra 2 tablespoons of brown sugar to the topping.
The spice ratios in this recipe are authentic to Ruth’s Chris, but feel free to adjust them to your preference. Some people love extra cinnamon, while others prefer more nutmeg. Start with the recipe as written and adjust in future preparations.
Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave for 1-2 minutes or reheat the entire casserole covered in a 325°F oven for 15-20 minutes.
This casserole can be frozen before baking for up to 2 months. Wrap it tightly in plastic wrap and aluminum foil. Bake from frozen at 350°F for 50-60 minutes, covering with foil if the topping browns too quickly.
For a bourbon version similar to Ruth’s Chris restaurants, add 2 tablespoons of bourbon whiskey to the milk mixture for an elevated, sophisticated flavor.
