Can I make this casserole ahead of time?
Yes. Assemble the casserole up to 2 days ahead, cover, and refrigerate. Add the pecan crumble topping just before baking to keep it crispy.
What does browning the butter do for this recipe?
Browned butter adds a nutty, complex flavor that elevates the sweet potato base beyond standard casseroles and mimics the steakhouse version.
Can I use candied pecans instead of making the crumble?
Store-bought candied pecans can work, but homemade crumble with brown sugar and cinnamon sugar gives better texture and control over sweetness.
How do I know when the sweet potato casserole is done baking?
The filling should be set but still slightly jiggly in the center when gently shaken. The pecan topping should be golden brown and fragrant.
Can I substitute the pecans with another nut?
Walnuts or chopped almonds work as alternatives, though pecans provide the classic steakhouse flavor and slight bitterness that balances the sweetness.
