Ingredients
For the Sweet Potato Base:
- 4 cups mashed sweet potatoes (about 3–4 large sweet potatoes)
- ½ cup unsalted butter, melted
- ½ cup packed brown sugar
- 2 large eggs, beaten
- ½ cup whole or evaporated milk
- 1 teaspoon vanilla extract
- ½ teaspoon ground cinnamon
- ¼ teaspoon ground nutmeg
- Pinch of salt
For the Pecan Topping:
- 1 cup chopped pecans
- ½ cup all-purpose flour
- ½ cup packed brown sugar
- ¼ cup unsalted butter, melted
Optional Variation:
Swap the pecan topping for mini marshmallows if you prefer a gooey, golden layer instead of the nutty crunch.
Instructions
- Preheat the oven to 350°F (175°C). Grease a 9×13-inch casserole dish with butter or non-stick spray.
- Bake the sweet potatoes: Scrub them clean, pierce with a fork, and bake for 45–60 minutes until tender. Once cool enough, scoop out the flesh and mash until smooth.
- Prepare the base: In a large bowl, mix the mashed sweet potatoes with melted butter, brown sugar, eggs, milk, vanilla, cinnamon, nutmeg, and a pinch of salt. Stir until creamy and well blended.
- Transfer to dish: Spread the sweet potato mixture evenly into the prepared baking dish, smoothing the top with a spatula.
- Make the topping: In another bowl, combine pecans, flour, brown sugar, and melted butter. Mix until crumbly.
- Assemble and bake: Sprinkle the topping evenly over the sweet potato layer. Bake uncovered for 25–30 minutes, or until the topping is golden and crisp.
- Cool and serve: Let it rest for about 10 minutes before serving. The texture firms up slightly, making it easier to slice — though honestly, spoonfuls straight from the dish are just as heavenly.
Tips & Tricks
- For extra creaminess: Use an electric mixer instead of a masher for the sweet potatoes.
- Make ahead: Assemble the casserole (without baking) the day before, cover, and refrigerate. Bake when ready to serve.
- For lighter sweetness: Cut the brown sugar in half — the natural sweetness of the potatoes will still shine through.
- Texture tip: For an extra-crispy topping, broil for the last 1–2 minutes (keep a close eye!).
Substitutions & Variations
- Vegan-friendly: Use plant-based butter, coconut milk, and a flaxseed egg (1 tbsp flaxseed + 3 tbsp water).
- Nut-free: Replace pecans with crushed pretzels, oats, or cornflake crumbs for texture.
- Gluten-free: Use almond flour or gluten-free all-purpose flour in the topping.
- Dessert twist: Add a drizzle of maple syrup or a sprinkle of sea salt caramel before baking for an extra indulgent flavor.
Frequently Asked Questions
Can I use canned sweet potatoes?
Yes — just drain them well before mashing. Canned yams in syrup can make it overly sweet, so rinse them lightly if needed.
