This Gordon Ramsay key lime pie recipe creates the perfect balance of tangy citrus and sweet creaminess in every bite. The homemade graham cracker crust provides the ideal foundation for the light, airy filling that carries the distinctive punch of fresh lime.
I discovered this recipe during a summer dinner party where I needed something refreshing yet elegant. The bright citrus flavor earned so many compliments that it's now my signature dessert when entertaining.
Ingredients
- Graham crackers crumbs: Forms the perfect buttery foundation that complements the tangy filling
- Unsalted butter: Binds the crust together while allowing you to control the saltiness
- Egg yolks and whites: Creates structure while keeping the filling light and airy
- Sweetened condensed milk: Delivers creaminess and balanced sweetness without being overwhelming
- Fresh lime juice: Provides that signature tangy flavor — true Key limes offer the most authentic taste
- Lime zest: Intensifies the citrus flavor and adds beautiful specks of color
- Heavy cream: Creates a pillowy topping that balances the tartness of the filling
- Confectioners sugar: Sweetens the whipped cream without leaving any graininess
- Vanilla extract: Adds depth to the whipped cream topping
Step-by-Step Instructions
- Prepare the crust:
- Mix graham cracker crumbs and melted butter thoroughly until the texture resembles wet sand. Press this mixture firmly into your pie plate, using the bottom of a measuring cup to create an even layer along the bottom and sides. The crust should be about 1/4 inch thick throughout. Bake at 160°C for exactly 15 minutes until it turns a light golden brown and feels set to the touch. Allow to cool for a full 10 minutes before adding the filling.
- Create the filling base:
- Whisk the egg yolks and whole egg vigorously for about 2 minutes until the mixture becomes noticeably thicker and takes on a pale yellow color. This process incorporates air that will give your filling a lighter texture. Slowly pour in the condensed milk while continuing to whisk, then add the lime juice and zest. The acid in the lime juice will begin to thicken the mixture immediately.
- Incorporate the egg whites:
- In a separate clean, dry bowl, beat the egg whites with an electric mixer on medium high speed for about 3 minutes until they form stiff peaks that stand straight up when the beaters are lifted. Using a rubber spatula, gently fold these whites into the lime mixture using a figure eight motion. Take care not to overmix and deflate the whites as they provide the airy texture.
- Bake the pie:
- Pour the combined filling into your cooled crust and smooth the top with a spatula. Bake for 13 to 15 minutes, watching carefully near the end. The pie is done when the filling is just set but still has a slight jiggle in the center. Overbaking will cause the filling to crack. Cool completely at room temperature before transferring to the refrigerator to chill for at least 6 hours.
- Finish with whipped topping:
- Just before serving, whip the cold heavy cream with confectioners sugar and vanilla extract until it holds medium peaks that slightly curl over when the beater is lifted. This usually takes about 3 minutes. Spread or pipe this over the chilled pie and garnish with additional lime zest and thin lime slices.

The fresh lime zest is my secret weapon in this recipe. When I first made this pie without it, the flavor was good but somewhat flat. Adding that extra tablespoon of zest transformed the dessert with bright aromatic notes that make people close their eyes and smile with their first bite.
Perfecting Your Crust
The graham cracker crust forms the foundation of this dessert, so taking time to get it right pays off. For the best texture, process store bought graham crackers in a food processor until you achieve fine, even crumbs. The butter should be completely melted but not hot when mixed with the crumbs. Press the mixture firmly into your pie plate, creating an even layer with slightly thicker edges. This prevents the crust from crumbling when you slice the finished pie. If your crust seems too dry and isn't holding together well, add an additional tablespoon of melted butter.
The Magic of Key Limes
True Key limes differ significantly from the Persian limes commonly found in grocery stores. They're smaller, more aromatic, and have a distinctive flavor that balances sweetness and acidity perfectly. If you can find fresh Key limes, they're worth the extra effort of squeezing despite their smaller size. One pound of Key limes yields approximately 1/2 cup of juice. If Key limes aren't available, regular limes make an excellent substitute, though the flavor will be slightly different. Bottled Key lime juice works in a pinch, but always zest your limes fresh rather than using dried zest for the brightest flavor.
Serving Suggestions
This key lime pie presents beautifully and tastes even better with thoughtful accompaniments. Serve slices chilled but not ice cold to fully appreciate the flavors. For an elegant presentation, add a sprig of fresh mint alongside each serving. The pie pairs wonderfully with coffee or an after dinner liqueur. For a more substantial dessert course, add a small scoop of vanilla ice cream on the side. During summer months, consider freezing the pie for 30 minutes before serving for a semifrozen treat that's especially refreshing. Always use a warm, clean knife for slicing, wiping the blade between cuts for picture perfect slices.

Frequently Asked Questions
- → Can I use regular limes instead of Key limes?
Yes, you can substitute regular limes for Key limes. The flavor will be slightly different as Key limes are more aromatic and tart. If using regular limes, you might want to use a bit less juice (about ¼ cup) as they tend to be more acidic.
- → Why do I need to refrigerate the pie for so long?
The 6-hour (or overnight) refrigeration allows the filling to fully set and the flavors to develop. This crucial step ensures the proper consistency and enhances the tangy lime flavor throughout the pie.
- → Can I make this pie ahead of time?
Absolutely! This pie is perfect for making ahead. The crust and filling can be made 1-2 days in advance and kept refrigerated. Add the whipped cream and garnishes just before serving for the freshest presentation.
- → Why do we beat the egg whites separately?
Beating the egg whites until stiff and folding them into the filling creates a lighter, more airy texture. This technique, which differs from some traditional Key lime pie methods, results in a less dense final product with a subtle meringue-like quality.
- → What can I use if I don't have graham crackers?
If graham crackers aren't available, you can substitute digestive biscuits, vanilla wafers, or even ginger snap cookies. Simply crush them to the same fine consistency and proceed with the recipe as directed.
- → How do I know when the pie is properly baked?
The pie is done when the edges are set but the center still has a slight jiggle when gently shaken. It will continue to set as it cools. Avoid overbaking, which can cause the filling to crack or become rubbery.
