Easy Gluten-Free Lemon Meringue Pie

Easy Gluten Free Lemon Meringue Pie is my adaptation of my mother's perfect lemon meringue pie recipe. Using a dairy-free lemon meringue recipe and substituting gluten-free flour in the filling, I also used a frozen 9-inch gluten-free crust, and made this lemon meringue pie recipe using fresh lemons. 


Allergy note: This lemon meringue pie recipe uses eggs but no milk. Gluten free crust may contain milk.

The Best Way to Separate Egg Yolks 

My mother was very specific in how to separate egg yolks and egg whites. She told me to have two CLEAN bowls ready ahead of time and to use a different clean dry whisk or egg beater for each. This video shows a method of separating egg whites from yolks.

INSTRUCTIONS: 

Preheat oven to 350 degrees.

Pie Crust:
Unwrap one 9-inch frozen gluten-free pie crust or pastry shell and place it into the preheated oven. As the pie crust begins to soften, use a fork to poke holes into the bottom and sides of the crust so it doesn't bubble up. Continue baking 5-7 minutes or until golden brown. Remove from oven and allow to cool.

Lemon Filling: 

Using a medium saucepan, first add the dry ingredients: sugar, gluten-free flour, cornstarch, and salt. Whisk together well and then gradually stir in the water, vanilla (if used), lemon juice, and lemon zest. Cook over medium-high heat and continue to stir well until mixture comes to a boil. Stir in the butter.

How I Make Grated Lemon Zest

How Do You Zest a Lemon?

You might be wondering what is lemon zest? The "zest" is what you get when you grate a lemon rind. I use a firm fresh lemon and just grate the yellow part all around the lemon. Don't shave the white part or it gives a bitter taste. You can use a special lemon zester but I use the tiniest part of my metal food grater to make lemon zest.

I use a clean stiff brush to dust the zest from the grater into a bowl.

To the egg yolks in a small bowl, add a small amount of the hot sugar mixture from the saucepan. Immediately add the egg yolk mixture back into the saucepan and stir or whisk continuously as you bring the mixture to a boil. Continue stirring until the mixture is thick. Because gluten-free flour is used, the mixture may take a little longer to thicken. Remove saucepan from heat.

Use a spatula to help pour the lemon filling into the baked gluten-free pie crust. Allow to cool for a few minutes.

Meringue:

In a medium to large glass or Pyrex bowl with steep sides, whip the egg whites until they are foamy and beginning to stand up in peaks. Add the sugar a little at a time, until the egg white mixture stands up in stiff peaks that only droop a little at their tops. If you wish to add vanilla extract, add it now and whip lightly into the mixture.

Spoon the egg white mixture over the cooled lemon filling in the pie shell. Use a spatula to spread the meringue over the entire filling and onto the edges of the pie crust. The meringue will be very high but will become lower as the pie bakes. 

Bake in the preheated oven for 10 minutes or until the peaks and edges of the meringue are golden brown. 

Cool on a rack or refrigerate.

Best lemon meringue pie I have ever made!  

I prepared this to take along to visit family who live on a mountain road. Despite all the twisting and turning on the way, the lemon meringue stayed ON TOP OF THE PIE and did not slide or shrink. That's never happened when I made other lemon meringue pie recipes, and it was a big hit with everyone!
