Mother's Squash Pie

Squash pie is the original American custard pie, and this heirloom recipe uses mashed butternut squash instead of canned pumpkin for a filling that’s silkier and naturally sweeter. The triple-spice combination of ginger, nutmeg, and cinnamon gives it that familiar autumn warmth without being heavy-handed.

What makes this recipe different is the double-boiler step. Heating the milk and squash together before combining with the egg mixture means the filling goes into the pie shell already warm. This cuts baking time significantly and helps the custard set more evenly from edge to center.

The two-temperature bake is key: a hot blast at 400°F (200°C) for the first 10 minutes sets the crust and gets the filling moving, then dropping to 350°F (175°C) finishes it gently so the custard doesn’t crack or curdle. The pie is done when the center barely jiggles. It will firm up as it cools.

Kitchen Tips

• Don’t boil the milk-squash mixture in the double boiler. Boiling can cause the eggs to scramble when added.
• A tablespoon of flour in the filling acts as insurance against a runny center.
• Let the pie cool to room temperature before refrigerating. Condensation from a hot pie makes the crust soggy.
• Freshly grated nutmeg makes a noticeable difference over pre-ground.

Variations

• Use acorn squash or kabocha in place of butternut for a slightly different flavor profile.
• Add a splash of bourbon or dark rum to the filling for a boozy holiday twist.
• Top with sweetened whipped cream and a dusting of cinnamon before serving.
