How to Make No-Bake Vegan Key Lime Pie

It’s so easy to make this vegan key lime cheesecake. Simply follow these steps:

Step One: Prepare the Crust

We’ll use this vegan graham cracker crust recipe for the perfect buttery crust!

A hand presses the crust into a pie pan.

To prepare the graham cracker crust, combine graham cracker crumbs with softened coconut oil. Stir these two together and then press into the bottom of a prepared pie pan. Place this in the fridge to allow the crust to set.

Step Two: Create the Lime “Jello”

A lime mixture in the bottom of a sauce pan.
This vegan keylime pie begins with making a lime vegan jello.

To make this no-bake pie filling, we going to create a vegan jello. Here’s how to do it: combine lime zest, lime juice, water, agar flakes and sugar in a small saucepan. Bring that to a low boil over medium heat and then reduce heat to a simmer and cook for about 5 minutes.

If you’re wondering about agar flakes, it’s a jello-type thickener that’s made from sea algae. You can find it in health food stores or see the link below to buy it online.

Remove the saucepan from heat and then transfer that mixture to a bowl and put it in the fridge to cool.

Step Three: Prepare the No-Bake Key Lime Pie Filling

A lime pudding is in a food processor.
This vegan key lime pie silken tofu recipe is so easy to make!

In a food processor combine vegan cream cheese, vegan vanilla yogurt, silken tofu, and just a little bit of fresh spinach (for color). Pulse these until smooth and creamy.

Add the cooled lime jello mixture into the yogurt mixture and pulse again until smooth. Pour this filling into the cooled vegan key lime pie crust.

Lime filling is being poured into the prepared pie crust.

Step Three: Cool until Set

Place the vegan lime pie in the fridge and let it set for up to two hours before serving.

Be sure to have some vegan whipped cream handy. I love making my coconut Vegan Whipped Cream because it’s so easy and so healthy! But there are plenty of store-bought dairy-free whipped creams these days!

How to Thicken Vegan No-Bake Key Lime Pie Filling

In this recipe, I’m using agar agar flakes to thicken the key lime pie filling. I highly recommend agar because it’s a no-carb thickener that’s perfect for a vegan diet. Agar is made from red sea algae and is much more easily available than it used to be.

Finding Vegan Graham Crackers

There are a lot of accidentally vegan products available these days, but for some reason finding a vegan graham cracker can be challenging. Why? Because a lot of graham crackers include honey. Some vegans choose not to eat honey. For me, honey is just not on my radar screen. It’s as if you can look at levels of veganism and I’m completely content to be what I refer to as a Secular Vegan. I’m passionate about my veganism, just not rigid.

Anyway, there are some brands of graham crackers that do not include honey, such as the original Nabisco Graham Crackers. You can also purchase Nabisco graham cracker crusts and they are dairy-free as well. Finally, I have been known to use Teddy Grahams or even vanilla Oreo Cookies in place of graham crackers too.

Light Key Lime Pie

There’s something about combining tart and sweet that cannot be denied. This eggless key lime pie is great for people with diet sensitivities too. This is also a low sugar key lime pie recipe vegan (see tips below for making it sugar-free).

If you’re into crunchy crusts with a sweet and creamy filling (with a little bit of tartness to boot), you’re gonna love this easy vegetarian key lime pie.

Besides, you know I’m really into vegan pies, right? For example, there’s my super easy Vegan Peanut Butter Pie. It’s like taking a bite of love in a pie crust! 😍

More Vegan Pies

Of course, if you want to add a little variety to your vegan desserts, I happen to have a thing for pies, so you could also check out this Vegan Lemon Meringue Pie if you love sweet but tart desserts. Of course, you could never go wrong with a Chocolate Meringue Pie. And speaking of meringue, everyone loves this sweet and creamy Coconut Meringue Pie! They’re all so good.

Marly’s Tips

Use these tips and tricks for making this healthy key lime pie recipe perfect every time:

  • This recipe makes a homemade graham cracker crust, but you can buy graham cracker crusts at the store — most are egg and dairy-free (be sure to check the ingredients)
  • I use vegan yogurt for this recipe, but you could transform this into a coconut key lime pie by using a can of coconut cream (like the kind sold at Trader Joe’s or Sprouts with lots of thick cream) instead. Be prepared for a more coconut flavor, but the lime and the coconut work well together. A key lime pie coconut milk infused is fabulous
  • Make this into a vegan gluten-free key lime pie by using gluten-free graham crackers for the crust. That means a gluten-free dairy-free key lime pie would be great for most everyone!
  • To make a vegan key lime pie avocado infused, simply add 1/2 cup mashed avocado to the food processor with the vegan cream cheese and pulse until smooth.
  • Key limes are a hybrid fruit and they’re smaller than the average lime and a bit more aromatic. If you don’t have key limes in your area, use lime juice with a little bit of lemon juice added. That should give you that distinctive key lime flavor
  • For vegan cream cheese, I use either Tofutti or Daiya cream cheese
  • Be sure and allow this key lime pie recipe time to chill in the fridge before serving
  • You’ll notice spinach leaves in the recipe, this is added for color purposes and will not flavor the pie filling
  • Make this a sugar-free key lime pie by substituting Swerve for the sugar in the recipe below
  • To make a raw key lime pie, simply replace the crust with a nut-based crust like the one on my Raw Vegan Cheesecake
  • Agar agar is sold in most health food stores and online and is derived from red algae and is a perfect thickener!

You can see why this is the best vegan pie recipe!

    I love Key Lime Pie and what a dream to be able to make it Vegan!

    Is there a substitute for tofu, it’s not that I don’t like it, but recently found out I am allergic to soy, as well as dairy and wheat. I use a lot of vegan substitutes like Daiya cream cheese and So Delicious dairy free coconut milk yogurt. I would buy more Silk if it wasn’t mostly soy products.

    • Avatar thumbnail image for MarlyMarly

      Hi Arianne. Sorry to hear about your soy allergy. This recipe might be difficult to make soy-free. If I were going to try it, I would probably add a cup of soaked and drained cashews and coconut milk yogurt. Blend that with everything else until it’s very smooth. I can’t guarantee that will set as firmly as the one above, but it should taste pretty good. Let me know how it goes!

    I bet basil leaves instead of spinach leaves would be even better

    • Avatar thumbnail image for MarlyMarly

      Hi Wendy! Well, the thing I like about spinach leaves is it adds a little color without impacting the flavor of the pie. The basil would definitely add some flavor. I can’t decide if I would like that or not, but it would definitely be fun to try it! Let me know how it goes!

      I love key lime pie,but where do l get the agar flakes and vegan produce?

    • Avatar thumbnail image for MarlyMarly

      You can buy agar agar flakes at most health food stores. I bought mine at Natural Grocers and it can be found in the Asian section. The other products, like the vegan cream cheese and vegan yogurt, can be purchased at health food stores, but I also find it in the health food section of our grocery store.

    What is the fat content ? Since you are using coconut oil , what is the cholesterol level in the pie?

    I can’t wait. I’m going to make this tomorrow. I found key limes today for the first time in years!

      Key limes are a great find!

    Do youwant the jello to be runny? In the directions it just says cooled, so not solid? And I plan to use gelatin which i know isn’t vegan but as a substitue it says online that it is a 1:1 ratio.

    • Avatar thumbnail image for MarlyMarly

      Hi Mariah! Thanks for your visit. I refrigerate the vegetarian jello in this recipe, which means it firms up. This is a good question and I will add it to the recipe notes. I can’t speak to gelatin because I never use it, since it’s not vegetarian. I really love working with agar agar and you can find it at health food stores and Asian markets as well.

      Where I live the only healthfood store got closed down a few years ago, and next is in seattle 4hr away.

    • Avatar thumbnail image for MarlyMarly

      Oh, that is a long drive. I feel your pain. We didn’t use to have many health food stores and the ones we had were not very good. Kinda nut and twiggy! But now we have several. I will keep my fingers crossed for you that some return to your town. In the meantime, you can buy agar agar online. That’s the brand I use. It is pricey, but it lasts a long time. I know this won’t arrive in time for tomorrow’s dinner, but thought I’d give you that resource for next time. Hugs!!

    I must have done something wrong. Mine came out so bitter I couldn’t eat it. : (

      Did you use key limes?

  8. Avatar thumbnail image for MarlyThyra Rutter Reply

    I substituted corn starch for the agar agar (since I couldn’t find it) it’s also vegan- I think my limes weren’t quite ripe enough as it came it a tad too tart, but otherwise, the texture was wonderfl.

  9. Avatar thumbnail image for MarlyMeghan James Reply

    Wayyy too tart. I could hardly eat it. I’d use less limes and more sugar.

    • Avatar thumbnail image for MarlyMarly

      Hi Meghan. Thanks for your comment. Sweetness is such a personal thing. We really love the tart, lightly sweet flavor of this pie. If you want more sweetness, you could drizzle a little bit of agave nectar over the top of each slice. Hope that helps!
