Vegetarian Key Lime Pie Recipe

If you’re trying to avoid animal products or just prefer a pie that has a less heavy feel without sacrificing flavor, this is the recipe for you.
It combines the tartness of fresh lime juice, the creamy richness of coconut milk (or another non-dairy milk), and the sweetness of maple syrup or agave nectar, making it a more inclusive take on the original. The crust? It’s typically made from graham crackers, offering the perfect combination of crunch and sweetness that complements the smooth, tangy filling.

- Lime zest (adds an extra punch of citrus flavor)

Cooking Instructions
Now, let’s get into the kitchen and whip up this fantastic vegetarian key lime pie! Don’t worry, it’s super easy, and the results will be absolutely mouthwatering. Here’s how to do it step-by-step:
-
Prepare The Crust
- Preheat your oven to 350°F (175°C).
- Crush your graham crackers in a food processor or place them in a zip-top bag and crush with a rolling pin until they resemble fine crumbs.
- In a bowl, mix the graham cracker crumbs, melted coconut oil (or butter), and sugar until everything is well combined.
- Press the mixture evenly into the bottom of a pie dish (9-inch size works perfectly). Use the back of a spoon to firmly pack it down.
- Bake the crust for about 8-10 minutes, or until it’s golden brown and fragrant. Remove from the oven and let it cool completely before adding the filling.
-
Make The Filling
- In a medium saucepan, whisk together the coconut milk, lime juice, lime zest, maple syrup (or agave), and cornstarch (or arrowroot powder).
- Place the saucepan over medium heat and cook, stirring constantly, until the mixture begins to thicken. This will take around 5-7 minutes.
- Once thickened, remove from the heat and stir in the vanilla extract for added flavor.
- Pour the filling into the cooled graham cracker crust. Smooth the top with a spatula for an even finish.
-
Chill The Pie
- Refrigerate the pie for at least 4 hours, or ideally overnight, so the filling can set and become nice and firm.
- Once set, slice up the pie and garnish with fresh whipped cream, lime slices, or toasted coconut flakes, if desired.
-
Serve And Enjoy
- Your vegetarian key lime pie is now ready to be served! The tangy, creamy, and sweet flavors make for a perfectly refreshing treat.
Ingredient Science Spotlight
The ingredients in key lime pie aren’t just picked for their taste-they each play a specific role in the texture, consistency, and flavor profile of the pie.
- Coconut milk: The full-fat version is key for giving the pie its creamy texture without needing dairy. The fats in coconut milk mimic the rich texture you would normally get from eggs and cream, allowing the filling to hold its shape and provide that luxurious mouthfeel.
- Lime juice: The star of the show! The acidity from the lime juice creates the signature tang of key lime pie. The tartness also helps balance out the sweetness, preventing the pie from being overly sugary. The zest, on the other hand, enhances the lime flavor and adds depth.
- Cornstarch: Used to thicken the filling, cornstarch ensures that the pie has a custard-like consistency without the need for eggs. It works by absorbing the liquids and swelling when heated, creating a gel-like texture that holds everything together.
- Graham crackers: The base of the crust is made from graham crackers, which have a subtle honey flavor and crunchy texture. When mixed with fat (butter or coconut oil) and sugar, they create the perfect firm, slightly crumbly crust.
Expert Tips
- Use fresh limes: It’s tempting to use bottled lime juice, but fresh lime juice and zest make all the difference in flavor. Fresh limes are much more aromatic and offer a more intense tang.
- Don’t skip the chill time: The longer you let the pie chill, the better it will set. If you try to cut it too soon, the filling may not be firm enough and could ooze out.
- Make it gluten-free: Swap the graham crackers for gluten-free graham-style crackers or use a blend of gluten-free oats and coconut flakes for a more nutty crust.
- Add a bit of salt: A pinch of salt in the filling can bring out the sweetness and help balance out the acidity from the lime. It’s a small touch, but it elevates the overall flavor profile.
- Whipped cream is your friend: A dollop of whipped cream on top adds richness and complements the tart filling. You can make a dairy-free whipped cream using coconut cream or even whip up some aquafaba (the liquid from a can of chickpeas) for a vegan version!
Recipe Variations
While the traditional vegetarian key lime pie is a crowd-pleaser, there are plenty of ways to make this dessert your own:
- Vegan Version: For a fully plant-based pie, use coconut milk, coconut cream, and a plant-based sweetener like agave nectar. You can even use a cashew-based whipped cream topping for extra richness.
- Baked Version: If you prefer a slightly firmer, more traditional pie, you can bake the filling in the crust at 350°F (175°C) for 10-15 minutes before chilling. This will give the filling a more custardy texture.
- Chocolate Crust: For a richer twist, use chocolate graham crackers instead of regular ones. The bitterness of the chocolate pairs wonderfully with the tangy lime.
- Fruit Variations: Try blending some fresh berries (like raspberries or strawberries) into the filling for a fruity variation. Just be sure to strain out any seeds before adding to the pie.
Final Words
Key lime pie is one of those desserts that never fails to impress. Its balance of tangy, sweet, and creamy flavors combined with a crunchy crust makes it a universal favorite. The vegetarian version ensures you can enjoy all the flavor with none of the animal products-while still capturing the spirit of the original.
Whether you’re making it for a family dinner or bringing it to a potluck, this vegetarian key lime pie is a guaranteed showstopper. And the best part? It’s simple, straightforward, and can be easily customized to meet a variety of dietary needs.

What Ingredients Can Be Used As A Replacement For Eggs In A Vegetarian Key Lime Pie?
To replace eggs in a vegetarian key lime pie, options include silken tofu for creaminess, agar-agar as a gelling agent, or a combination of non-dairy yogurt and cornstarch to help thicken the filling.
Can I Use A Store-bought Pie Crust For A Vegetarian Key Lime Pie?
Yes, store-bought pie crusts can be used, but you should ensure they are labeled vegetarian (without any animal-based ingredients). Some store-bought crusts may contain butter, so be sure to choose a plant-based or vegan option.
How Can I Make The Key Lime Pie Filling Dairy-free?
To make the filling dairy-free, use coconut milk, almond milk, or soy milk in place of condensed milk. You can also opt for a non-dairy cream cheese or a mixture of coconut cream and sweetener to achieve a rich, creamy texture.
What Is The Best Way To Achieve A Tangy Flavor For A Vegetarian Key Lime Pie?
The best way to achieve a tangy flavor in a vegetarian key lime pie is by using fresh lime juice and lime zest. Key limes, if available, offer a more authentic and tart flavor, but regular limes can also be used as an alternative.
How Can I Make A Vegan Key Lime Pie Instead Of Just Vegetarian?
To make a vegan key lime pie, use plant-based substitutes for all dairy and egg products. Replace any dairy ingredients with coconut milk, almond milk, or a vegan cream cheese alternative, and use silken tofu or a dairy-free yogurt for creaminess.
Can I Use A Different Type Of Citrus Instead Of Lime For The Pie?
While traditional key lime pie uses key limes, you can substitute regular limes, or experiment with other citrus fruits like lemons, oranges, or grapefruits for a different twist on the flavor. However, the tanginess of lime is characteristic of key lime pie.
Do I Need To Bake A Vegetarian Key Lime Pie?
Most vegetarian key lime pie recipes do not require baking, as the filling sets in the refrigerator. However, if you choose to bake the crust, you can pre-bake it before adding the filling to ensure it’s firm and golden.
How Long Should I Refrigerate A Vegetarian Key Lime Pie Before Serving?
Refrigerate the pie for at least 4 hours or overnight to allow the filling to set properly. The longer the pie sits in the fridge, the firmer the texture will become, allowing for cleaner slices when serving.
