There's a reason guacamole is the most popular dip at any party. Not only is it delicious, but fresh, green guacamole can only last for so long. Leave out a bowl of guac for a few hours, and it's not long before it develops an unappealing brown top layer that everyone is sure to avoid.

So, is there anyway to ensure that your prized guacamole will last a little longer without turning brown? Turns out there's a simple solution for keeping your guac green for a few more days. Keep reading for step-by-step instructions on the best way to keep guacamole from turning brown.

How to Keep Guacamole From Turning Brown

The solution lies with good ol' H2O. Topping off guacamole with water keeps air, at least in part, from being able to penetrate the guacamole, which keeps it from browning. By using this simple technique, you can keep guacamole from browning for up to three days.

  1. Once you're ready to store your guacamole, place it in an airtight storage container (like this Amazon best seller). You may also use a bowl and cover it tightly with plastic wrap.
  2. Use a spoon to flatten the surface of the guac and remove any air bubbles.
  3. Add about a ½ inch of water to the top of the guacamole. Make sure the water covers the whole surface of the guac.
  4. Put the lid or covering on the container, and store the guac in the fridge for up to three days.
  5. When you're ready to enjoy your guac, gently pour out the water and stir before serving.

Why Does Guacamole Turn Brown?

It's a question we're all faced with, as we've all been victim to brown guac at some point. Avocado flesh turns brown when an enzyme in avocado reacts with oxygen in the air. This process is known as oxidation. And because avocado is the primary ingredient in guacamole, you'll notice your guac will change in color as well.

You may find that the top layer of your guac is brown, while the guac towards the bottom of the bowl is still green. This is because the top layer is guarding the bottom layers from oxygen in the air.

Can You Eat Brown Guacamole?

Brown avocado is safe to eat, so long as you store it in the fridge and consume it within a few days. It may be slightly more mushy and/or bitter than green guac, but it's still safe to eat. If you didn't store your guac with a layer of water on top, you can simply scrape off the top layer to reveal the bright bring guacamole underneath.
