Savory Sweet Potato Pie

Why This Savory Sweet Potato Pie Works

During boiling, the sweet potatoes soften all the way through, so they mash very smooth. Once the butter and heavy cream go in, the warm potatoes melt the butter and soak up the cream. Everything blends into a thick, silky mash instead of a loose filling. When the eggs are mixed in, they spread through that warm potato mixture and wait to set in the oven.

In the skillet, the onion and garlic slowly soften in the olive oil. As they cook, they lose their sharp bite and start to taste sweeter and milder. Mixed into the potatoes, they spread that gentle onion and garlic taste through every bite instead of sitting in chunks.

In the oven, the heat firms up the eggs and melts the parmesan into the potatoes. The filling goes from a loose mash to a sliceable pie that still feels soft and creamy. At the same time, the pie crust bakes and stays sturdy around the edges, so the rich sweet potato center holds together when cut.

Mistakes To Avoid

Boiling the sweet potatoes too long makes them waterlogged, so when they’re mashed the mixture turns loose and runny. In the oven this kind of filling doesn’t set well, so the pie cuts into saggy slices that slump out of the crust.

Adding the eggs while the sweet potatoes are still hot can cause the eggs to start cooking in little bits right in the bowl. Those tiny scrambled pieces stay in the filling and bake into rubbery chunks instead of a smooth, custardy texture.

Pouring the filling into a raw, cold crust straight from the fridge and overfilling it often leads to a soggy bottom. The wet filling soaks into the dough before it has a chance to firm up, so the base stays pale and soft instead of holding its shape.

Pulling the pie from the oven while the center still jiggles a lot leaves the middle undercooked. As it cools, the outside may slice fine but the center stays mushy and almost pudding-like instead of cutting into neat wedges.
