Ingredients
In our Weight Watchers Key Lime Pie recipe, we focus on simple, health-conscious ingredients that deliver the signature tart and zesty flavors of this classic dessert while keeping calories in check. Below, we list the ingredients in the order they’re used—starting with the crust, followed by the filling, and finally the topping—to ensure a smooth preparation process.
Crust Ingredients
- 1 ½ cups crushed reduced-fat graham crackers: We use these as the base for a lighter crust; crush them finely for even texture.
- 2 tablespoons granulated sugar: A touch to enhance sweetness without overpowering.
- ¼ cup unsalted butter, melted: Opt for a reduced-fat version if available; melt it just until liquid for easy mixing.
Filling Ingredients
- 1 can (14 ounces) fat-free sweetened condensed milk: This is our key ingredient for creamy texture; pour it in next for the pie’s body.
- ½ cup fresh key lime juice: Freshly squeezed for that authentic tart punch—aim for about 4-5 limes to yield this amount.
- 1 tablespoon key lime zest: Grated finely from the limes; add it right after the juice to amplify the citrus aroma.
- 4 large egg yolks: These bind the filling; separate them carefully to avoid any whites mixing in.
Topping Ingredients
- 1 cup light whipped topping: We top with this for a fluffy, low-calorie finish; keep it chilled until ready to use.
- Optional: Fresh lime slices: Slice thinly for garnish; use 4-6 slices to add visual appeal and extra zest.

Tools and Equipment
To prepare our Weight Watchers Key Lime Pie with ease and precision, we rely on a few essential tools that streamline the process and ensure the pie’s signature tart and creamy texture comes out perfectly. Let’s break down the key items we’ll need, organized by their role in the recipe for better flow.
Must-Have Tools
We recommend gathering these core tools before starting, as they directly support the steps from mixing the crust to chilling the final pie:
- Pie dish (9-inch): This is crucial for baking our reduced-fat graham cracker crust and holding the tangy filling. Opt for a glass or ceramic version for even heat distribution and a golden finish.
- Mixing bowls (medium and large): Use these to combine ingredients like the crushed graham crackers for the crust or the key lime filling. A large bowl works best for whisking the egg yolks and condensed milk to avoid splatters.
- Measuring cups and spoons: Accuracy is key in our Weight Watchers recipe, so precise measurements ensure the pie stays within those 5 SmartPoints per serving. For example, use a 1-cup measuring cup for the graham crackers and a tablespoon for lime juice.
- Zester or microplane: Essential for grating fresh key lime zest, which adds vibrant flavor without extra calories. We love how it captures the aromatic oils for that authentic Key Lime Pie tang.
- Whisk or electric mixer: This helps us blend the filling smoothly, incorporating the fat-free sweetened condensed milk and egg yolks for a light, airy result.
Additional Equipment for Efficiency
For smoother preparation, especially if you’re making this pie for gatherings, consider these extras that enhance our process:
- Food processor or rolling pin: If crushing the graham crackers, a food processor speeds things up for a fine, even texture in the crust. Alternatively, use a rolling pin with a resealable bag for a no-mess option.
- Spatula: Perfect for spreading the light whipped topping evenly over the cooled pie, ensuring a professional-looking finish.
- Oven and refrigerator: A standard oven set to 350°F bakes the pie to perfection, while the refrigerator chills it for at least 2 hours to set the filling firmly.
By having these tools ready, we can transition seamlessly from the ingredients stage to baking, maintaining the recipe’s focus on healthy, flavorful results.
Instructions
Let’s guide you through creating our lighter Weight Watchers Key Lime Pie step by step, using the fresh ingredients and tools we’ve prepared to achieve a tart and creamy dessert that’s both healthy and irresistible.
Prepare the Crust
First, we preheat our oven to 350°F to ensure even baking for a crisp base. In a medium mixing bowl, we combine 1 ½ cups of crushed reduced-fat graham crackers and 2 tablespoons of granulated sugar, stirring them together until evenly mixed for a balanced sweetness that complements the tart filling.
Next, we add 4 tablespoons of melted unsalted butter to the mixture and use a fork to blend everything until it forms a crumbly texture that holds together when pressed—this creates a sturdy yet light crust. We transfer the mixture to a 9-inch pie dish and press it firmly against the bottom and up the sides using the back of a spoon or our fingers, ensuring an even layer for optimal structure.
Finally, we bake the crust in the preheated oven for 8-10 minutes until it’s lightly golden and fragrant, setting the stage for the vibrant flavors of our Key Lime Pie.
Make the Filling
Once the crust has cooled for about 10 minutes, we start on the filling by whisking 3 large egg yolks in a separate mixing bowl until they’re smooth and pale, which helps incorporate air for a silky texture.
We then add 1 can (14 ounces) of fat-free sweetened condensed milk, ½ cup of fresh key lime juice, and 1 tablespoon of key lime zest, whisking vigorously until the mixture thickens and turns a vibrant green hue—this step captures the pie’s signature tartness while keeping it light. For the best flavor, we recommend using freshly squeezed juice to enhance the zesty, refreshing notes that make this dessert stand out.
Pour the filling into the prepared crust, smoothing it out with a spatula to ensure even distribution, which promises a consistent creamy bite in every slice.
Bake the Pie
We place the assembled pie in the oven preheated to 350°F and bake it for 15-18 minutes, or until the filling is set around the edges but still slightly jiggly in the center—this gentle bake helps maintain the pie’s smooth, velvety consistency without overcooking.
As it bakes, the aroma of tangy lime and sweet cream will fill our kitchen, signaling that our Weight Watchers Key Lime Pie is transforming into a guilt-free treat. Once done, we remove the pie from the oven and let it cool on a wire rack for about 30 minutes to lock in the flavors.
Chill and Serve
After cooling, we cover the pie and refrigerate it for at least 3 hours or overnight to allow the filling to firm up and develop its full tangy-sweet profile, resulting in a refreshingly cool dessert that’s perfect for any occasion.
Just before serving, we top the pie with 1 cup of light whipped topping, spreading it evenly for a fluffy contrast to the creamy base, and optionally garnish with fresh lime slices for a pop of color and extra zest. Slice and enjoy the pie’s bright, citrusy flavors that make it a confident choice for our healthy eating plans.
Make-Ahead Instructions
One of the best features of our Weight Watchers Key Lime Pie is its flexibility for make-ahead preparation, allowing us to enjoy a fresh, tangy dessert without last-minute rush. By planning ahead, we maintain the pie’s signature tart and creamy texture while adhering to healthy eating goals.
Preparing the Crust in Advance
We can prepare the crust up to 3 days ahead to streamline assembly. Follow these steps:
- Crush the reduced-fat graham crackers and mix with sugar and melted unsalted butter as outlined in our earlier instructions.
- Press the mixture into the 9-inch pie dish and bake until golden.
- Allow it to cool completely on a wire rack, then wrap tightly with plastic wrap and store in the refrigerator.
Making the Filling Ahead
The filling holds up well when made in advance, giving the key lime flavors time to intensify. We suggest preparing it 1 to 2 days before serving:
- Whisk the egg yolks, fat-free sweetened condensed milk, fresh key lime juice, and key lime zest until thickened.
- Pour the mixture into the cooled crust if assembling immediately, or transfer it to an airtight container and refrigerate separately.
- Note: Do not bake the filling until you’re ready to assemble the full pie to avoid over-setting.
Assembling and Storing the Pie
For full assembly, we can complete the pie up to 24 hours in advance:
- Bake the filled pie as per the step-by-step instructions until set.
- Cool it on a wire rack for 1 hour, then refrigerate for at least 4 hours or overnight to firm up.
- Once chilled, cover the pie loosely with plastic wrap and keep it in the refrigerator.
Storage Tips and Serving Guidelines
To preserve freshness and minimize SmartPoints impact, we follow these guidelines:
| Storage Method | Duration | Key Tips |
|---|---|---|
| Refrigerator | Up to 3 days | Keep the pie covered to prevent drying; add the light whipped topping and lime garnish just before serving to maintain texture. |
| Freezer | Up to 1 month | Wrap the fully assembled pie (without topping) in freezer-safe wrap, then thaw in the refrigerator overnight before adding topping and serving. |
By following these make-ahead strategies, we ensure our Weight Watchers Key Lime Pie remains a guilt-free, flavorful treat ready for any occasion.
