Ingredients
Scale
Sweet Potato Mixture
- 3 lbs sweet potatoes (5–6 medium)
- 6 tbsp melted butter
- 1/2 cup sugar
- 2 large eggs
- 2 tsp vanilla extract
- 1 tsp cinnamon
- 1 tsp salt
- 1/4 cup half-and-half
Brown Sugar Streusel Topping
- 3 tbsp softened salted butter
- 1 cup brown sugar
- 1/3 cup flour
Instructions
- Preheat and Prepare Sweet Potatoes: Preheat your oven to 400°F (204°C). Pierce each sweet potato several times with a fork to allow steam to escape while baking. Place them directly on the oven rack and bake for 50–60 minutes until they are very soft when pierced with a fork.
- Mash Sweet Potatoes: Once baked and cool enough to handle, scoop out the flesh from the sweet potatoes into a large mixing bowl. Mash them until smooth, ensuring there are no lumps.
- Mix Sweet Potato Ingredients: To the mashed sweet potatoes, add the melted butter, sugar, eggs, vanilla extract, cinnamon, salt, and half-and-half. Mix everything thoroughly until well combined and creamy.
- Spread Mixture: Transfer the sweet potato mixture into a greased 9×13 inch baking dish, spreading it evenly.
- Prepare Streusel Topping: In a separate bowl, combine the softened salted butter, brown sugar, and flour. Mix until coarse crumbs form and the mixture is crumbly.
- Top the Casserole: Sprinkle the brown sugar streusel mixture evenly over the sweet potato layer in the baking dish.
- Bake the Casserole: Reduce oven temperature to 350°F (177°C). Bake the casserole for 20–25 minutes until the streusel topping is golden brown and crisp.
- Rest and Serve: Remove the casserole from the oven and let it rest for a few minutes before serving to allow it to set slightly and cool down for best texture.
Notes
- You can prepare the sweet potatoes ahead of time by baking and mashing them a day in advance, then assembling just before baking.
- Use salted butter in both the sweet potato mixture and streusel for a balanced flavor.
- If you prefer a nuttier topping, feel free to add chopped pecans to the streusel mix.
- For a dairy-free version, substitute half-and-half and butter with coconut milk and vegan butter alternatives.
- Make sure the sweet potatoes are thoroughly cooked and soft to achieve the best mash consistency.
