Ingredients:

  • 3 lbs Sweet Potatoes (Jewel or Garnet), peeled and cubed
  • 1/2 cup Unsalted Butter, softened
  • 1/2 cup Light Brown Sugar, packed
  • 2 Large Eggs, lightly beaten
  • 1/4 cup Whole Milk or Half-and-Half
  • 1 teaspoon Vanilla Extract
  • 1 teaspoon Ground Cinnamon
  • 1/2 teaspoon Ground Nutmeg
  • 1/2 teaspoon Fine Sea Salt
  • 1/2 cup All-Purpose Flour (for streusel)
  • 1/3 cup Light Brown Sugar, packed (for streusel)
  • 1 cup Pecans, roughly chopped
  • 4 tablespoons Unsalted Butter, melted (for streusel)
  • 1/8 teaspoon Pinch of Salt (for streusel)

Instructions:

  1. Preheat your oven to 350°F (175°C). Lightly grease the 9x13 inch casserole dish with butter.
  2. Place the cubed sweet potatoes in a large saucepan and cover with cold, salted water. Bring to a boil, then reduce heat and simmer until the potatoes are fork-tender (about 15-20 minutes).
  3. Drain the potatoes thoroughly using a colander, allowing excess steam to escape for a minute or two.
  4. Transfer the hot potatoes to a large mixing bowl. Mash them until very smooth. (For the best texture, use an electric hand mixer.)
  5. Add the softened butter, brown sugar, eggs, milk, and vanilla extract to the mashed potatoes. Mix until fully incorporated.
  6. Whisk in the ground cinnamon, nutmeg, and sea salt. Mix until the base is perfectly smooth and the color is uniform.
  7. Pour the sweet potato base into the prepared casserole dish and smooth the top with a spatula.
  8. In a separate medium bowl, combine the flour, brown sugar, chopped pecans, and a pinch of salt. Stir briefly.
  9. Pour the 4 tablespoons of melted butter over the dry streusel ingredients. Toss or stir with a fork until large, defined crumbs form.
  10. Evenly distribute the pecan streusel mixture over the sweet potato base, covering the entire surface.
  11. Bake for 45–50 minutes, or until the sweet potato base is set and the streusel topping is golden brown and bubbling slightly.
  12. Remove the casserole from the oven and let it rest for 10–15 minutes before serving. This allows the internal filling to set up completely.
