What You Need

You can find the full printable recipe, including ingredient quantities, below. But first, here are some explanations of ingredients and steps to help you make this recipe perfect every time.

Here are the ingredients you’ll need for this recipe:

  • Graham cracker crust — You can use a store-bought graham cracker crust (which are Accidentally Vegan) or you can make a homemade Vegan Graham Cracker Crust. Of course, I prefer homemade.
  • Key lime zest — You can find bags of little key limes in the produce section of most grocery stores in the spring and summer. Use a microplane or box grater to zest the limes, but watch your fingers! You can substitute regular lime zest if you’re unable to find key limes.
  • Key lime juice — Juice several key limes (see more on that below) or substitute regular lime juice.
  • Sweetened condensed milk — You can buy coconut cream sweetened condensed milk in the store these days. I usually find them in the baking section next to the other condensed milk products. Or you can make homemade vegan sweetened condensed milk.
  • Vegan cream cheese — I use either Tofutti’s or Daiya vegan cream cheese.
  • Silken tofu — Here’s more on buying tofu at the grocery store. You can usually find silken tofu in the produce section or at healthy food stores.
  • Coconut oil — I’m using coconut oil to create a firmer custard. I recommend using refined coconut oil because it has a more neutral flavor, but if you like coconut combined with lime (it’s a famous flavor combination), then use unrefined coconut oil.
  • Color — You don’t have to add any color, but if you prefer a green hue to your pie, you can add several fresh spinach leaves (never frozen spinach), but be sure to use a high-speed blender rather than a food processor in order to blend the spinach leaves. Otherwise, you can add 1 to 2 drops of organic green food coloring.

Ingredient Spotlight

What are Key Limes?

Key limes are a hybrid fruit and they’re smaller than the average lime and a bit more aromatic. You’ll commonly find them in the summer in the produce section of most grocery stores. 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.

How to Make Vegan Key Lime Pie

  1. Prepare the crust, press it into a pan, bake for 8 to 9 minutes, then set it aside to cool.

How to Juice Key Limes

Key limes are not your typical citrus fruit. They’re much smaller than standard limes and even lemons. Here are some favorite tips for zesting and juicing key limes.

To finely grate or zest key limes:

  1. Wash the limes.
  2. Only zest the bright outside part of the lime, the white skin underneath is bitter and not suited for pies.
  3. Microplane: Using a microplane zester, it takes about 4 minutes to zest 6 key limes. Hold the microplane in one hand and the lime in the other and gently press the lime across the microplane, turning the lime as you go.
  4. Grater: Use a grater with fine holes and and press the lime against it, turning the lime to zest only the outer layer.
  5. Knife: You can use a knife but it takes a bit longer. Hold the lime down on a cutting board and cut off thin strips of the peel. Dice the lime strips into fine pieces.

To juice key limes:

  1. It takes around 18 key limes to create 1/2 cup of juice. You can supplement mostly key lime juice with some lime juice.
  2. Microwave the key limes for 20 to 30 seconds to soften them.
  3. Cut a key lime in half (cutting through the rounder side rather than stem to stem).
  4. Remove any obvious seeds.
  5. Press it onto a juicer to soften it (or use a fork).
    A hand holds a key lime on a glass zester. There are fresh key limes around it along with several key limes that have already been juiced.
  6. Then press the lime between your fingers to get all the juice.
  7. Repeat with the remaining limes.

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 and some vegans choose not to eat honey. Some brands, such as the original Nabisco Graham Crackers, do not include honey.

You can also purchase Nabisco graham cracker crusts and they are dairy-free as well. I have substituted gluten-free graham crackers, Teddy Grahams, or even vanilla Oreo Cookies in place of graham crackers.

Serving Suggestions

Serve this tasty summer pie as is, or add any of these as toppings:

Storage Tips

Store the entire pie or individual slices in an airtight container in the fridge for up to 4 or 5 days. The pie can also be frozen for up to 2 months. Serve the pie frozen by allowing it to thaw for a few minutes.

Marly’s Tips

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

  • You can 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 of the cream cheese.
  • Make this into a vegan gluten-free key lime pie by using gluten-free graham crackers for the crust.
  • Make this a sugar-free key lime pie by substituting Swerve for the sugar.
  • To make a raw key lime pie, simply replace the crust with a nut-based crust like the on 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!

    I am confused as I read some of the comments. People asking about agar agar flakes and vegetarian jello? I don’t see these ingredients in the recipe or in the blog post. I made it exactly like the recipe says and put it in the fridge but now am wondering if it is going to set?
