Instructions
Prep & Sweet Potato Base
- Preheat to 350°F. Lightly grease a 9×13 inch baking dish with butter or nonstick spray.
- Place potatoes in a large pot, cover with cold water, add a pinch of salt, and bring to a boil. Simmer 15 to 20 minutes until very tender. Drain well and return to the warm pot to steam off excess moisture for 2 minutes.
- Mash the potatoes until smooth. Stir in melted butter, brown sugar, maple syrup, milk, vanilla, cinnamon, nutmeg, and salt. Let cool 2 to 3 minutes so the mixture is warm, not hot.
- Whisk the eggs in a small bowl. Stir a spoonful of warm potato mixture into the eggs to temper, then stir eggs into the pot until fully incorporated.
- Spread the sweet potato mixture evenly in the prepared dish, smoothing the top.
Pecan Topping & Bake
- In a bowl, mix pecans, brown sugar, flour, cinnamon, and salt. Drizzle in melted butter and stir until sandy clumps form. If using oats, fold them in now.
- Sprinkle the topping evenly over the potatoes. Bake 30 to 35 minutes until the topping is golden and the edges are gently bubbling. The center should be set; leftovers should reheat to 165°F.
- For extra crunch, broil 1 to 2 minutes, watching closely to prevent burning.
- Let the casserole rest 10 minutes so it slices neatly and the topping stays crisp.

FAQs
Can I use canned yams Yes. Drain very well, pat dry, and reduce added sugar to taste since canned yams are often sweetened.
How far in advance can I make this Assemble up to 2 days ahead, keep the topping in a separate container, then sprinkle on just before baking for best crunch.
How do I keep the topping crispy Bake uncovered, avoid excess moisture in the base, and broil briefly at the end if needed.
Can I skip the eggs Yes. Use the flax egg option. The texture will be slightly less custardy but still delicious.
What size pan should I use A 9×13 inch dish is perfect. For a deeper casserole, use a 9×9 and add 5 to 10 minutes to the bake time.
