Ingredients

  

Filling

• 4 large sweet potatoes (about 3 pounds), peeled and cubed
• 0.5 cup granulated sugar or brown sugar for a richer taste
• 2 large eggs
• 1 tsp pure vanilla extract
• 0.5 cup milk whole or 2%
• 0.5 cup unsalted butter melted
• 0.25 tsp salt

Pecan Topping

• 0.5 cup all-purpose flour
• 0.33 cup brown sugar packed
• 0.25 tsp ground cinnamon optional but cozy
• 0.5 cup chopped pecans
• 0.25 cup unsalted butter softened

Instructions

 

• Step 1: Boil the peeled, cubed sweet potatoes in a large pot of water until fork-tender (about 15 minutes). Drain well and mash until completely smooth—no lumps!
• Step 2: In a mixing bowl, combine the mashed sweet potatoes, sugar, eggs, vanilla, milk, melted butter, and salt. Stir until silky and well blended. Taste and adjust sweetness if needed.
• Step 3: Transfer the filling to a buttered 9×13-inch baking dish. Use a spatula to smooth it into an even layer.
• Step 4: In a small bowl, mix flour, brown sugar, cinnamon (if using), and pecans. Cut in the softened butter using a fork until the mixture resembles wet, clumpy sand.
• Step 5: Sprinkle the pecan mixture evenly over the sweet potato layer. Bake at 350°F (175°C) for 35–40 minutes, or until the topping is golden and slightly crispy.

Notes

Make Ahead: Assemble the casserole (filling + topping) a day in advance. Refrigerate and bake just before serving. Add 5–10 minutes if baking from cold.

Nut-Free: Replace pecans with oats or crushed pretzels.

Dairy-Free: Use plant-based milk and vegan butter alternatives.

Sweeter Topping: Add mini marshmallows halfway through baking for a gooey layer.

Texture Tip: Use a hand mixer for ultra-smooth sweet potatoes.
