How to make low-carb crustless custard pie

Ready to see how this low-carb indulgence comes together with kitchen-staple ingredients?

Ingredients for the custard pie laid out on a table
  • Eggs — Let the eggs sit out until they reach room temperature. This will help the custard set evenly.
  • Sugar — You can adjust the amount based on your preferences to get just the right amount of sweetness.
  • Vanilla extract — This adds a warmth and subtle, sweet flavor. Use pure vanilla extract for the best results.
  • Flour — You can use white wheat or all-purpose flour to thicken the custard.
  • Warm spices — Cinnamon and nutmeg add just the right amount of warmth.
  • Whole milk — This adds richness and creaminess to the custard. I don’t recommend substituting with anything else because other, thinner milks could make the custard watery.

How to make low-carb crustless custard pie

Step 1: Preheat the oven to 350°F and spray a pie plate with nonstick cooking spray.

Step 2: With an electric or stand mixer, beat the eggs with the sugar and vanilla until the eggs are well-beaten and the mixture is uniform in color.

Step 4: With the mixer running, alternate adding 1 tablespoon of the flour mixture with a ¼ cup of the milk until everything has been added and all the ingredients are well-combined.

Step 5: Pour the mixture into the prepared pie plate

Recipe tips and tricks

  • Use room-temperature eggs for a smooth custard that blends easily without any lumps.
  • Whisk the ingredients thoroughly to ensure everything is evenly combined before baking.
  • Let the pie cool completely before slicing so it has time to set.

Substitutions and variations

  • You can use a sugar substitute like granulated monk fruit sweetener or stevia for a lower-carb version of the custard.
  • I sometimes like to add a pinch of cardamom for a more complex warm-spice flavor.

What to serve with this recipe

For a classic combination, finish your dessert with some sugar-free whipped cream. A little dollop always looks right at home on top of a slice of pie.

I also enjoy fresh fruit on the side. Raspberries, blueberries, or sliced strawberries are my favorites!

For maximum coziness, treat yourself to a slice of custard pie with a cup of keto hot chocolate!

Storage and freezing

  • Let the custard pie fully cool before covering to avoid condensation. Once cooled, store leftovers covered in the refrigerator for up to 3 days.
  • Custard doesn’t freeze well, so I would not recommend storing your custard pie in the freezer.
