Sweet Potato Streusel Casserole

This is the sweet potato casserole that earns its spot at the holiday table. Baked sweet potatoes mashed with butter, brown sugar, eggs, milk, and a generous pour of bourbon create a custardy, spiced base that smells like autumn in Louisiana.

Cinnamon and nutmeg do the expected work, but it’s the bourbon that sets this apart. Half a cup goes in, and as it bakes, the alcohol cooks off while leaving behind that warm, oaky, vanilla-tinged depth that pairs with sweet potatoes like they were made for each other.

The streusel topping is where the texture magic happens. Rolled oats, flour, brown sugar, and butter cut together until pea-sized, then tossed with chopped pecans. Bake it until heated through, then hit it under the broiler for 3 minutes to crisp that top into a golden, crunchy lid. That broiler step is optional but highly recommended. Without it, you have a soft topping. With it, you have crunch that shatters with every spoonful.

Pro Tips

• Bake the sweet potatoes rather than boiling them. Baking concentrates their natural sugars and keeps the filling from getting waterlogged.
• Watch the broiler like a hawk. Three minutes under high heat takes the streusel from golden to charred fast.
• Let the casserole rest for 10 minutes after baking so the filling sets up slightly and doesn’t run when scooped.

Variations

• Swap bourbon for dark rum for a more tropical, molasses-forward warmth.
• Add a layer of mini marshmallows under the streusel for a classic sweet-meets-crunchy combination.
• Fold in a mashed ripe banana for extra natural sweetness and moisture.
