Why Eggless and Sugar-Free?
There are several reasons why you might want to make an eggless and sugar-free version of lemon meringue pie. Many people have egg allergies, while others follow a vegan lifestyle, which excludes eggs from their diet. Additionally, with more people reducing or eliminating sugar intake for health reasons, finding alternatives to traditional sweeteners is essential. Whether you're baking for yourself or a group with diverse dietary needs, this recipe accommodates both egg-free and sugar-free requirements while retaining the essence of a great lemon meringue pie.
Key Substitutes for Egg and Sugar
Before diving into the recipe, it’s important to understand the primary substitutes used for both eggs and sugar in this version of the pie.
Egg Replacements
Eggs serve two main purposes in lemon meringue pie: they help thicken the filling and create the meringue topping. To replace eggs in the filling, you'll need a thickening agent such as cornstarch, which will help achieve the same creamy consistency. For the meringue topping, aquafaba—a liquid from a can of chickpeas—is a great egg white substitute. When whipped, it mimics the texture of meringue beautifully.
Sugar Replacements
For the sweet component, you can use natural sweeteners such as stevia or erythritol, both of which are excellent sugar-free alternatives. They provide the sweetness needed for the filling and meringue without the calories or blood sugar spikes.
Ingredients for the Eggless and Sugar-Free Lemon Meringue Pie
Let’s break down the ingredients you'll need to make this pie, including the pie crust, lemon filling, and meringue topping.
Crust
While the filling and meringue are the stars of lemon meringue pie, the crust is equally important as the base that holds everything together. You can use a pre-made sugar-free pie crust, but making your own is easy and allows for better control over the ingredients. Here's a simple crust recipe:
1 ½ cups almond flour (for a gluten-free option)
¼ cup melted coconut oil or vegan butter
1-2 tbsp erythritol (optional for a slightly sweeter crust)
A pinch of salt
Lemon Filling
The lemon filling is the heart of this pie, and its tangy flavor is essential to balancing out the sweetness of the meringue. Here are the ingredients you'll need:
1 ¼ cups water
½ cup fresh lemon juice (about 3-4 lemons)
1 tbsp lemon zest
½ cup erythritol or stevia (adjust to taste)
¼ cup cornstarch (for thickening)
¼ cup coconut milk (or any plant-based milk for added creaminess)
A pinch of turmeric (optional, for color)
Meringue Topping
The meringue traditionally relies on egg whites, but aquafaba—a liquid found in canned chickpeas—works wonders as an egg replacement in this recipe. You'll need the following ingredients for the meringue:
¾ cup aquafaba (liquid from a can of chickpeas)
¼ tsp cream of tartar (helps stabilize the aquafaba)
2-3 tbsp erythritol or stevia (to sweeten)
½ tsp vanilla extract (optional, for added flavor)
Step-by-Step Recipe
Now that we have our ingredients ready, let’s walk through the steps to make this eggless and sugar-free lemon meringue pie.
Step 1: Prepare the Pie Crust
Preheat your oven to 350°F (175°C).
In a bowl, mix the almond flour, melted coconut oil (or vegan butter), erythritol, and a pinch of salt until the mixture resembles coarse crumbs.
Press the mixture evenly into the bottom of a 9-inch pie pan. Make sure it covers the bottom and sides of the pan.
Bake the crust for 10-12 minutes or until lightly golden. Once done, remove it from the oven and set it aside to cool.
Step 2: Make the Lemon Filling
In a medium saucepan, whisk together the water, lemon juice, lemon zest, erythritol, and cornstarch until well combined.
Heat the mixture over medium heat, stirring constantly. The cornstarch will start to thicken the mixture as it heats.
Once the mixture has thickened (about 5-7 minutes), remove it from the heat and stir in the coconut milk and a pinch of turmeric for color, if desired.
Pour the lemon filling into the pre-baked pie crust and let it cool while you prepare the meringue.
Step 3: Whip the Aquafaba Meringue
In a large mixing bowl, add the aquafaba and cream of tartar. Using an electric mixer, whip the mixture on high speed until it begins to form soft peaks (this usually takes around 5-10 minutes).
Gradually add the erythritol, one tablespoon at a time, and continue to whip until stiff peaks form, much like traditional meringue. This can take another 5-7 minutes.
Once the meringue has reached stiff peaks, gently fold in the vanilla extract if you're using it.
Step 4: Assemble the Pie
Spread the whipped aquafaba meringue evenly over the lemon filling, making sure to seal the edges so that the meringue doesn’t shrink during baking.
Create some decorative peaks on the meringue using the back of a spoon or spatula for a beautiful finish.
Step 5: Bake the Pie
Preheat your oven to 375°F (190°C). Bake the pie for 10-12 minutes, or until the meringue turns golden brown on top.
Keep a close eye on it to avoid burning the meringue.
Once the meringue is beautifully browned, remove the pie from the oven and let it cool completely at room temperature.
After cooling, place the pie in the fridge to chill for at least 3-4 hours before serving. This will help the lemon filling set properly.
Tips for the Perfect Eggless and Sugar-Free Lemon Meringue Pie
Aquafaba Tips: Make sure to use room-temperature aquafaba for best results when whipping. Also, if you're using canned chickpeas, make sure the liquid is unsalted to avoid altering the taste of the meringue.
Sweetness Adjustment: Since erythritol and stevia can be sweeter than sugar, it's essential to taste as you go to adjust the sweetness according to your preference.
Thickening the Filling: Cornstarch is key for thickening the lemon filling, but if you find that it's not thick enough, you can increase the cornstarch slightly and cook it longer on the stove.
Storage: This pie is best enjoyed the same day it's made, but it can be stored in the refrigerator for up to 2 days. Be aware that the meringue may lose some of its fluffiness over time.
Final Thoughts
An eggless and sugar-free lemon meringue pie might seem like a challenge at first, but this recipe proves that it's entirely possible to make a delicious version that meets dietary restrictions. The tangy lemon filling, the crispy almond crust, and the fluffy aquafaba meringue come together to create a dessert that’s both satisfying and guilt-free. Whether you’re making this pie for a special occasion or as a healthy alternative to the classic recipe, you’ll find that it’s a crowd-pleaser every time.
