We love making guacamole from scratch. This is the best guacamole recipe we have tried. It is inspired by a guacamole frescos dish we like to order from our favorite Mexican restaurant in town and they make it tableside.

Keto Homemade Fresh Guacamole

Frequently Asked Questions

Can I use frozen avocados for this guacamole recipe?

I haven't tried this myself, but you can use frozen avocados if you're in a pinch. Thaw them completely and drain any excess moisture before mashing. Fresh will always give you better flavor and texture though.

What can I substitute for cilantro if I don't like it?

If you're not a fan of cilantro, swap it for fresh parsley or just leave it out. Green onion works well too if you want something different.

How long will my guacamole stay fresh in the fridge?

I cover mine the way I described above - pack it down, add a thin layer of lemon juice on top, and seal it tight. It keeps for 2-3 days in the fridge that way.

Is this guacamole recipe keto-friendly?

Yes! Avocados are packed with healthy fats and this whole recipe is only 4.7g net carbs per serving. Perfect for keto. Just watch your portions with the dippers.

Can I make guacamole ahead of time for a party?

Yes! I make it a few hours ahead all the time. Add a thin layer of lime juice on top and press plastic wrap right against the surface. That keeps it green until you're ready to serve.

How to pick the perfect ripe avocado for the best keto guacamole?

Picking a ripe avocado comes down to feel and outer appearance.

Look for one that is firm, but has a little bit of give to it when you squeeze it. If the avocado is squishy, it is too ripe. If the avocado is rock hard, it is not ready yet; however, these avocados are great to buy if you want to make guacamole a few days later.

The color of a ripe avocado is a dark, almost blackish green. If the avocado is green; many times, it is not ripe yet.

One trick I use to tell if an avocado is ready to eat – take the button stem off the top. If the flesh underneath is bright avocado green, then it is ready to be cut open and used. If that area under the stem is brownish in color, then it is overly ripe and the avocado will probably be brown inside as well.

How to prevent your guacamole from turning brown?

If you plan on eating all of your guacamole in one go, you don’t have to worry about storing it.

Unfortunately, guacamole can oxidize quickly and turn an unappealing brown color. The lime juice in the recipe helps to slow down the oxidation process, but I find that my guac still turns brown after I store it overnight unless I do an extra step to preserve it.

The best method I have used to store guacamole and keep it green is to cover it with a layer of lemon juice or water.

First, pack the guacamole down in an airtight container.

Then add a thin layer of lemon juice or water on top. This creates a barrier between the air and the guacamole to prevent oxidation from occurring. Using the lemon juice provides an additional antioxidant effect to further prevent any browning since it is filled with Vitamin C – a powerful antioxidant.

Next cover with a lid or plastic wrap and store in the refrigerator for up to 2-3 days.

Next time you reach for your guacamole, pour off the excess water or lemon juice and enjoy!

Keto foods you can pair with guacamole?

  • Pork rinds – These make excellent scoopers for guacamole during snack or game time.
  • Veggies – Try using celery, cauliflower, or sliced cucumber to scoop up your guacamole.
  • Keto tortilla chips – If you are really craving tortilla chips, make some low-carb tortilla chips using three ingredients!
  • Steak – I love adding a heaping spoonful of guacamole to my steak – especially a flat iron or skirt steak.
  • Eggs– Scrambled eggs or fried eggs with a side of guacamole makes for a delicious breakfast.
