Thanksgiving Sweet Potato Recipes: Pecan Streusel Bake

• Roasting rather than boiling keeps the potato flesh drier, so the mashed base needs less adjustment before it goes into the dish. Active time: about 25 minutes; cost: $$.
• An egg gives the filling a set, spoonable texture while evaporated milk adds richness from one shelf-stable can. Both are easy to measure, and neither requires a stand mixer.
• That pecan streusel is mixed in one bowl and scattered loosely, creating clear contrast with the soft filling. Use a timer for final baking to keep topping golden.

• 4 medium orange-fleshed sweet potatoes, scrubbed (1800 g)
• 1 cup evaporated milk (240 g)
• 2 large eggs, beaten (100 g)
• 1/2 cup packed light brown sugar (110 g)
• 4 tablespoons unsalted butter, melted, divided (57 g)
• 2 teaspoons vanilla extract (10 g)
• 1 1/2 teaspoons ground cinnamon, divided (4 g)
• 1/2 teaspoon kosher salt, divided (3 g)
• 1/4 teaspoon ground nutmeg (1 g)
• 3/4 cup all-purpose flour (90 g)
• 3/4 cup chopped pecans (85 g)
• 1/3 cup packed brown sugar (73 g)

Ingredient notes

• Orange-fleshed sweet potatoes, often labeled garnet or jewel, give the mash a vivid color and moist texture. Choose similarly sized potatoes so they roast at the same pace, and skip any with soft spots.
• Evaporated milk is concentrated canned milk, not sweetened condensed milk, and it brings richness without another dairy container. Whole milk can stand in, although the filling will be a little looser and less rounded overall.
• Light or dark brown sugar both work in the filling and topping. Dark brown sugar has more molasses character, while light keeps the casserole brighter; use whichever bag is already open, then pack it into cup.
• Pecans deliver crunch and toast quickly in the oven. Walnuts are a direct substitute, or leave nuts out and use an equal amount of old-fashioned oats for a softer, crumbly top with less bite.
• Unsalted butter lets the small amount of added salt stay predictable across brands. Melt it just until fluid, then cool before combining it with sugar; hot butter can make the topping greasy rather than crumbly.

1. 1Heat the oven

   Set a rack in the center and heat oven to 400°F. Line a rimmed baking sheet with foil and prick each sweet potato several times. Arrange them with space between so heat can circulate. Roast until a knife slides through the centers easily, about 50 to 55 minutes.

2. 2Roast potatoes

   Transfer potatoes to a board and let them stand until cool enough to handle. Split skins open, scoop flesh into a large bowl, and discard skins. Mash while warm with a potato masher until no large chunks remain. A few small pieces add welcome texture.

3. 3Mix filling

   Lower oven to 350°F. Grease a 9-by-13-inch baking dish with butter. Whisk mashed potato with evaporated milk, eggs, brown sugar, melted butter, vanilla, cinnamon, salt, and nutmeg. Stir until glossy and evenly combined, then scrape mixture into prepared dish. Smooth the surface with a spatula.

   

4. 4Build topping

   In a small bowl, stir flour, brown sugar, chopped pecans, cinnamon, and salt. Drizzle in melted butter and rub it through with a fork until damp clumps form. Scatter them across filling without pressing down. Leave a few uneven peaks for a crisper finish.

   

5. 5Bake the casserole

   Bake until filling is gently puffed and topping is deeply golden, 30 to 35 minutes. Rotate dish once if your oven browns unevenly. The center should no longer look wet and loose when the pan is nudged. Let it rest 10 minutes before serving.

6. 6Finish and serve

   Move the dish to a trivet and spoon portions from the warm edges inward. Add a light pinch of flaky salt or extra pecans only at the table. Serve warm with roast turkey, ham, or a crisp green vegetable for balance.

• Roast potatoes until completely tender; underdone pieces leave stubborn lumps in the mash. If one potato finishes early, remove it and let the others continue rather than forcing every potato out together.
• Measure the mashed potato after roasting, rather than guessing from raw weight. A dry measuring cup makes the filling consistent, especially when potato sizes vary from bag to bag.
• Use a glass or ceramic baking dish and set it on a rimmed sheet pan if carrying a full dish worries you. The sheet pan catches any butter drips and makes rotation simpler.
• Rest the bake before serving so the filling settles into neat spoonfuls. Cover only after it has cooled; trapped steam softens the topping you worked to keep crisp.

Spoon the casserole from its baking dish while it is warm, using a broad serving spoon to keep some topping on every portion. It fits beside herb-roasted turkey, gravy, and tart cranberry sauce, while a sharp green salad or simply cooked green beans keeps the plate from becoming too sweet. For a smaller meal, halve the recipe in an 8-inch square dish and begin checking the bake at 25 minutes. Time: 10 minutes; cost: $.
