How to Make Savory Sweet Potato Casserole

Creating this casserole is a straightforward journey that ends in a burst of flavor. Follow these steps for perfect results every time:

Preheat the oven to 375°F (190°C). This ensures that your casserole will bake evenly, forming that beautiful golden crust on top.
Peel and chop the sweet potatoes into even chunks. Take your time to make them uniform; this will help them cook at the same rate.
Boil the sweet potato chunks in salted water until fork-tender, about 15-20 minutes. Keep an eye on them to prevent overcooking; they should be soft but not mushy.
Drain the sweet potatoes and return them to the pot. Allow excess water to drain fully to prevent your casserole from becoming watery, which can muddle the flavors.
Add milk, Parmesan cheese, garlic powder, onion powder, salt, and pepper; mash until smooth. Use a strong arm or your trusty potato masher to achieve a creamy texture that’s still fluffy.
Pour the sweet potato mixture into a greased 9×13 inch baking dish. Spread it evenly, smoothing the top to prepare for the glorious topping.
In a bowl, mix melted butter, walnuts, and breadcrumbs for the topping. The butter ensures that every crumb toasts beautifully in the oven.
Sprinkle the topping evenly over the sweet potato mixture. Make sure it covers every inch; we want maximum crunch!
Bake for 25-30 minutes until the topping is golden brown. Keep an eye during the last few minutes to prevent burning.
Serve warm as a side dish. Relish in the smile this dish brings to your table as everyone raves over the flavors.

Tips: Taste your sweet potato mixture before baking—seasoning at this stage is key for the best outcome.

Overbaking: Keep an eye on the casserole—watch for a golden topping, but don’t let it turn too dark.
