This creamy avocado cilantro lime sauce is easy to make, taking just 5 minutes from start to finish. With only 6 ingredients, it's simple to prepare in a blender or food processor. This versatile sauce doubles as a dipping sauce for chips and veggies or as a topping for fish tacos. Featuring a tangy lime flavor and a hint of cilantro, it adds freshness to any dish.
Use a sharp knife and cutting board to cut the avocado in half, then use a spatula, spoon, or other utensil to scoop out the flesh and place it in a blender (or food processor).
Use measuring spoons to measure out the lime juice, garlic powder, and kosher salt (or juice a lime if needed) and add it into the blender, along with the whole cilantro leaves. Place the lid on the blender and blend on medium-low until the ingredients are well mixed (should be no longer than 1 minute, though you may need to stop once or twice to help them mix as the sauce will be thick).
Remove the lid from the blender and scrape down the sides with the utensil you used for the avocado. Use measuring cups to measure out then add in the sour cream to the blender. Put the lid on again and blend on low until the sour cream is incorporated (no more than 30 seconds).
Use the spatula to spoon the sauce into a bowl or other dish and serve! To store, place the sauce in an airtight container and keep in the fridge for 3 to 4 days.
Notes
Don't blend the sauce at too high a speed once it has the sour cream in it. That can cause the sauce to get air bubbles. You want to mix it at a lower speed and just long enough to incorporate everything.
If you want a thinner sauce, you can either add more lime juice or a little bit of the "water" from the sour cream container.
If you'd like a stronger cilantro flavor, increase the amount to either ¾ cup or 1 cup of fresh cilantro leaves.
