This gluten free key lime pie recipe is the kind of dessert that disappears fast at every cookout, potluck, and holiday table.
It has that classic tart and sweet combo everyone loves, but with a graham crust that anyone avoiding gluten can actually enjoy.
You only need a handful of ingredients and about twenty minutes of hands on time before the oven and fridge do the rest of the work.
I have made this pie more times than I can count for my family, and it always gets the same reaction: quiet at the table because everyone is too busy eating to talk.

Recommended Products for This Recipe
These are a few products I personally use and recommend for this recipe, based on making it in my own kitchen more times than I can count.
1. Schar Gluten Free Honeygrahams
These are the closest gluten free cracker I have found to a classic honey graham, both in flavor and in how well they hold together once crushed and baked into a crust.
They give you that familiar cinnamon sweetness without any weird aftertaste some gluten free products have.
2. Nellie and Joe’s Key West Lime Juice
Fresh key limes are tiny and take forever to juice, so I keep a bottle of this on hand for whenever the craving hits.
It has that true key lime tang without any of the effort.
3. OXO Good Grips Citrus Juicer
If you do go the fresh lime route, this juicer gets every last drop out without much arm strength needed.
It has saved me so much time compared to squeezing everything by hand.
4. Pyrex 9 Inch Glass Pie Plate
A glass pie dish lets you see exactly how golden the crust is getting while it bakes, which matters more than you would think for a graham crust.
It also transitions straight from oven to fridge without any issue.

Step-by-Step Instructions: How to Make Gluten Free Key Lime Pie
1. Preheat the Oven and Prep the Pan
- Preheat your oven to 350 degrees Fahrenheit.
- Lightly grease your 9 inch pie dish with a thin layer of butter or nonstick spray.
- Set the pan aside while you make the crust mixture.
2. Make the Gluten Free Graham Crust
- In a medium mixing bowl, combine the gluten free graham cracker crumbs and the granulated sugar.
- Pour in the melted butter and stir with a fork until every crumb is evenly moistened.
- The texture should look like wet sand and hold together when you press a bit between your fingers.
3. Press and Pre-Bake the Crust
- Transfer the crumb mixture into the prepared pie dish.
- Use the bottom of a measuring cup to press the crumbs evenly across the bottom and up the sides of the dish.
- Bake the crust for 8 to 10 minutes, until it looks set and slightly golden at the edges.
- Remove from the oven and let it cool on the counter for about 10 minutes while you prepare the filling.
This same Sugar Free Key Lime Pie Recipe uses a nearly identical crust method if you also need to cut back on sugar.
4. Whisk the Egg Yolks and Condensed Milk
- In a large mixing bowl, add the egg yolks.
- Whisk them on their own for about 30 seconds, until they lighten slightly in color.
- Pour in the sweetened condensed milk and whisk again until fully combined and smooth.
5. Add the Lime Juice and Zest
- Add the key lime juice, lime zest, and a pinch of salt to the egg yolk mixture.
- Whisk everything together until the filling is smooth and slightly thickened.
- The mixture will thicken naturally as the acid from the lime juice reacts with the condensed milk.
6. Bake the Pie
- Pour the lime filling into the cooled, pre-baked crust.
- Spread it into an even layer with a spatula.
- Bake at 350 degrees Fahrenheit for 15 minutes, just until the center is set but still has a slight jiggle.
- Avoid overbaking, since the filling should stay soft and creamy, not firm like a custard.
If you prefer more of a citrus punch, this Cranberry Lime Pie Recipe plays with a similar tart profile using cranberries alongside the lime.
7. Cool and Chill
- Let the pie cool at room temperature for about 30 minutes.
- Transfer it to the refrigerator and chill for at least 4 hours, though overnight is even better.
- The pie needs this time to fully set into clean, sliceable pieces.
8. Make the Whipped Cream and Serve
- Right before serving, add the heavy whipping cream and powdered sugar to a chilled mixing bowl.
- Beat with a hand mixer on medium high speed until soft peaks form, about 2 to 3 minutes.
- Spread or pipe the whipped cream over the chilled pie.
- Garnish with extra lime zest right before slicing and serving.
Tips for The Best Gluten Free Key Lime Pie
A few small details make a big difference in how this pie turns out, especially when it comes to the crust and the chilling time.
- Press the crust firmly and evenly, since a loose crust will crumble when sliced
- Do not skip pre-baking the crust, or it will turn soggy under the filling
- Let the pie chill the full time, since rushing this step leads to a runny slice
- Use room temperature egg yolks so they whisk together smoothly
- Add the whipped cream just before serving, not before chilling
For a citrus dessert with a completely different texture, try this Lemon Meringue Pie Recipe next, which swaps whipped cream for toasted meringue.
These Lime Crinkle Cookies are another great way to use up extra lime zest and juice if you have some left over.
Serving Suggestions
This pie is rich enough to stand on its own, but it pairs nicely with a few other desserts if you are building out a dessert table.
- Serve alongside fresh berries for extra color and brightness
- Pair with a scoop of vanilla ice cream on the side
- Add a light dusting of graham cracker crumbs over the whipped cream
- Set out lime wedges for anyone who wants an extra pop of tartness
If you are hosting, this Lemon Cheesecake makes a great second dessert option for guests who want something equally tangy but different in texture.
Another good pairing is this Strawberry Cream Cheese Pie, which brings a fruitier, less tart flavor to round out the table.
Variations of Gluten Free Key Lime Pie
Once you have the base recipe down, there is plenty of room to make it your own.
- Swap the graham crust for a gluten free vanilla wafer crust
- Use coconut cream instead of half the whipped cream for a tropical twist
- Add a thin layer of white chocolate on the crust before adding the filling
- Top with toasted coconut flakes instead of extra lime zest
- Make individual mini pies in a muffin tin for easy serving
This Lemon Icebox Pie Recipe uses a nearly identical no fuss method, just with lemon in place of lime.
If a creamier, less tart pie sounds appealing, this Coconut Cream Pie Recipe is worth trying next.
Storage and Reheating
This pie is meant to be served cold, so there is no reheating involved, just proper storage to keep it fresh.
- Cover the pie loosely with plastic wrap or foil and store in the refrigerator
- It keeps well in the fridge for up to 4 days
- Freeze the pie without the whipped cream topping for up to 2 months
- Thaw frozen pie overnight in the refrigerator before adding fresh whipped cream and serving
This No Bake Cheesecake Recipe follows a similar make ahead and chill approach, so it stores just as easily.

This Lemon Cream Pie Recipe has a fairly similar nutrition profile, since both desserts lean on condensed milk and citrus for the filling.
Health Benefits of Key Ingredients
While this is very much a dessert, a couple of the ingredients do carry some genuine nutritional upside.
- Lime juice is a good source of vitamin C, which supports immune function
- Egg yolks provide protein along with vitamin D and choline
- Heavy cream, in moderation, supplies fat soluble vitamins like A and D
- Lime zest contains plant compounds linked to antioxidant activity
This Banana Cream Pie Recipe also leans on eggs and dairy for its filling, so the nutritional benefits are fairly comparable between the two.

FAQs About Gluten Free Key Lime Pie
1. Is key lime pie filling naturally gluten free?
Yes, the filling itself is naturally gluten free since it only contains egg yolks, sweetened condensed milk, and lime juice.
The only part of a traditional key lime pie that typically contains gluten is the graham cracker crust, which this recipe solves by using certified gluten free graham crackers.
2. Can I use regular limes instead of key limes?
Yes, regular limes work well if key limes are hard to find.
You will need slightly fewer regular limes since they are larger, and the flavor will be a touch less tart but still delicious.
3. Why is my pie filling runny after chilling?
A runny filling usually means the pie did not chill long enough or was not baked quite long enough to set properly.
Give it the full 4 hours in the fridge, and check that your oven temperature is accurate with an oven thermometer if this keeps happening.
4. Can I make this pie ahead of time?
Absolutely, this pie is actually best made a day ahead since it needs time to chill and set fully.
Just hold off on adding the whipped cream topping until right before you plan to serve it.
5. How do I know when the pie is done baking?
The pie is done when the edges look set but the very center still has a slight jiggle when you gently shake the pan.
It will continue to firm up as it cools and chills, so a little jiggle in the middle is exactly what you want.
