How to Make Pecan Sweet Potato Casserole?
Making this Fall casserole is as easy as pie. You just mash, mix, layer, and bake your way to buttery heaven.
Step 1: Chop and boil sweet potatoes. Cut sweet potatoes into 1-inch pieces. Add to a large pot, cover with water, and boil for 20 minutes until fork-tender and ready for mixing.

Step 2: Drain and cool the potatoes. Drain well and let sweet potatoes steam-dry in the pot for 2 minutes. This keeps them from being watery when you start mixing.
Step 3: Mix the sweet potato filling. Add the drained sweet potatoes, brown sugar, melted butter, milk, eggs, vanilla, cinnamon, and salt to a large mixing bowl. Use a hand mixer to blend until smooth—no lumps left!
Step 4: Fill the baking dish. Lightly grease a 9×13-inch baking dish. Spoon in the sweet potato filling and use a spatula to smooth it into a nice, even layer.

Step 5: Make the pecan topping. In a separate bowl, stir together chopped pecans, brown sugar, flour, and melted butter. Mix until it’s well blended and the pecans are glossy and coated.

Step 6: Add the topping and bake. Sprinkle the pecan crumble evenly over the sweet potatoes. Bake uncovered at 350°F for 35 minutes until golden and bubbly with a toasty aroma filling your home.
Step 7: Cool slightly and serve. After baking, let the casserole cool for 10 minutes. This helps the top crisp up, allowing everyone to enjoy it.

Tips for the Best Pecan Sweet Potato Casserole
This dish turns out tastiest when you follow these simple tips, straight from my kitchen to yours.
- Use fresh sweet potatoes: They will taste sweeter and bake up soft, not watery or stringy.
- Don’t overmix the base: Too much mixing can make it dense instead of nice and fluffy.
- Toast the pecans first: It brings out their flavor, making the topping extra nutty and crunchy.
- Taste before adding salt: Sweet potatoes vary—sometimes you need a pinch more salt, sometimes less.
- Let it cool before serving: Gives the topping time to set, making it crispy rather than soggy or soft.

- Add mini marshmallows on top: Makes it gooey and sweet, reminding every bite of cozy childhood memories.
