Step-by-step

  • Place the sweet potatoes in a large pot or dutch oven and cover them completely with water. Bring water to a boil. Reduce heat and simmer for 20 minutes or until the potatoes are tender.
  • Drain the water and allow the sweet potatoes to cool for 15 minutes.
  • Preheat oven to 350°F (177°C). Grease a 9x13 baking pan (or a similar size casserole dish, or a 12-inch deep oven-safe skillet). Set aside.
  • Place the potatoes in a large mixing bowl. Using a handheld or stand mixer, beat the potatoes until relatively smooth-- I like to leave some chunks for texture. For your reference, you will have about 4 cups of mashed sweet potatoes.
  • Add the butter, brown sugar, beaten, eggs, cream, vanilla, and salt. Spoon/pour the mixture into prepared pan.
  • For the topping: In a medium bowl, whisk the flour, brown sugar, and cinnamon together. Using a rubber spatula, fold in the melted butter and pecans until the mixture is totally combined. Spoon evenly over potatoes.
  • Bake for 30-40 minutes or until golden brown on top.
  • Allow to cool for 5 minutes, then top with a little fresh rosemary and a sprinkle of sea salt. Serve warm.
  • Make ahead tip: This is a great make ahead recipe! Here's how to get started 1-2 days before-- prepare potatoes through step 3, then prepare the topping. Cover each separately and refrigerate for up to 2 days. Then, assemble and bake. Assembled, unbaked casserole can be frozen up to 2 months. Thaw overnight in the refrigerator, bring to room temperature, and continue with step 5. Baked casserole can be frozen up to 2 months. Thaw overnight in the refrigerator, bring to room temperature, and bake at 350°F (177°C) until warmed through.

Boiling sweet potatoes whole with their skins intact prevents them from absorbing excess water, which directly avoids a watery, dense final puree. Starch molecules gelatinize during the twenty-minute boil, softening the cell walls so they accept butter, cream, and eggs smoothly without turning gluey. Handheld mixers provide control over the final consistency, allowing cooks to retain small vegetable fragments that offer contrasting bite against the rich dairy and sugar. When preparing the topping, melted butter binds flour, brown sugar, and chopped nuts into a cohesive mass rather than a loose scatter, ensuring uniform crispness across the baking dish.

Fat and Sugar Interactions in the Topping

Brown sugar contains molasses, which introduces moisture and acidity. This acid reacts with trace minerals, while the fat content from the unsalted butter coats the flour proteins to inhibit excessive gluten development during the thirty to forty minutes at 350 degrees Fahrenheit. Without this protective fat barrier, the flour would absorb too much moisture from the potatoes and steam rather than toast. Pecans contribute high oil content; as they bake, these natural oils fry the surrounding flour particles, producing a brittle crust that contrasts against the velvety interior.

  • Drain boiled potatoes thoroughly and allow them to rest for fifteen minutes to steam off residual surface moisture.
  • Keep the assembled, unbaked casserole covered in the refrigerator for up to two days before baking.
  • Freeze baked portions for up to two months, thawing them overnight in the refrigerator prior to reheating at 350 degrees Fahrenheit.
