Is Key Lime Pie Keto?
Most key lime pie recipes are not keto friendly, since they contain refined sugar, conventional sweetened condensed milk, and a traditional graham cracker crust with gluten. However, it’s easy to swap these ingredients to make a recipe for sugar-free key lime pie that tastes just as delicious!
Ingredients You’ll Need
This section explains how to choose the best ingredients for sugar-free key lime pie, what each one does in the recipe, and substitution options. For measurements, see the recipe card below.
Almond Flour Pie Crust – You can also use coconut flour pie crust for a nut-free variation.Sugar-Free Sweetened Condensed Milk – Helps make the creamy consistency, and it’s easy to make yourself! You may be able to make a dairy-free version if you need to by using coconut cream or full-fat coconut milk instead of heavy cream.Egg Yolks – Help the key lime pie filling “set” and adds to the rich and smooth mouthfeel.Besti Powdered Monk Fruit Allulose Blend – This one dissolves the best and tastes the most like sugar, all with 0g net carbs. You can use other powdered sugar substitutes, but many other brands have erythritol in them and have a tendency to crystallize when storing, so the texture may be gritty if not using Besti.Key Lime Juice – Get a bottled version like this for convenience, or squeeze your own limes. You can use regular or key limes for this juice.Lime Zest – Adds extra lime flavor with minimal extra carbs.Sea Salt – Balances the tart and tangy sweetness.Optional Garnishes – Thinly sliced fresh limes and sugar-free whipped cream.

Try these cool and summery pies next — all with no sugar whatsoever. The filling will not completely set until it sits in the fridge for 3-4 hours. Make and serve this pie easily with a few key tips:
Don’t skip the chilling time. Otherwise the pie will be too runny and hard to cut. Make clean slices. Use a sharp knife to cut the pie, wiping it clean between slices. Serve it soon. For best results, serve the pie within 24 hours of making it. The crust can be made ahead, but once the filling is added, the crust has the best texture within the first 24 hours after it sets.
