Tip: use a mortar and pestle or an authentic Molcajete to grind the onion and cilantro into a paste before adding the avocado. This really helps to develop the flavors and makes the guacamole so much better!

This simple recipe only requires a few ingredients, such as:

How to make guacamole

You can whip this guacamole with tomatoes up in just a few easy steps. Here is how to make this perfect guacamole salsa recipe at home:

Step 2: add the avocados

Add in the rest of the cilantro, the lime juice, pepperoncini, and tomatoes. Taste and season with salt and cumin as desired.

Tips for success

  • Instead of lime juice, substitute or combine some of the remaining liquid from the pepperoncini jar. The extra dash of juice adds extra flavor and spice to your guacamole salsa and tastes delicious. Feel free to add more lime juice as needed to balance out the flavors in this guacamole salsa.
  • Use Roma tomatoes, they have less water so you don’t end up with soupy guacamole.
  • Try to avoid using metal tools when preparing or mashing your avocado as much as possible since these contribute to a faster browning process.
  • If you cannot get your hands on some pepperoncini, another possible substitute would be jalapeno peppers. These are a bit spicier but provide a similar taste and texture in this dish.

How do I prevent my guacamole from browning?

Guacamole can last in the refrigerator for up to two days in an airtight container. Although, this dish is better when served fresh since avocado tends to brown quite quickly. If your guacamole is just slightly brown, remove those parts and add a bit extra lime juice for added freshness.

You can prevent browning in the fridge by covering the guacamole with a thin layer of water. Drizzle water over your guacamole in an airtight container, just enough to coat the entire surface. Seal it and place it in the fridge. When you are ready to enjoy some more guacamole, simply pour off the water and stir it up.

How do I know if my avocado is ripe?

            Whether or not your avocado is ripe or not will truly make or break your guacamole salsa. Stay away from perfectly green, firm avocados for this dish. Avocados are deep green or purple in color when ripe and will feel slightly squishy when pressure is applied. On the other hand, if your avocado is too mushy or dark in color, it can be overripe.

            I use the fruit often and tend to buy unripe avocados in advance and let them ripen on my counter until I am ready for some delicious guacamole. If you leave your avocado out alongside other fresh fruit, it tends to ripen a bit more quickly.

What type of tomatoes for guacamole?

Roma tomatoes are perfect for guacamole. They tend to have a lot less water content. This will help to give you that creamy, delicious guacamole. Nobody likes a watery or runny guac.

Guacamole with Tomatoes and Pepperoncini

Yield: 4 to 6 servings
Prep Time: 10 minutes
Total Time: 10 minutes

This easy guacamole salsa is studded with bright red tomatoes and tangy, zesty pepperoncini peppers. The secret to killer guacamole is creating a paste out of the onions and cilantro. This is the perfect recipe for those game days with your friends or on Taco Tuesday. Put it on anything from fajitas to toast. It is sure to be a hit!


  • half yellow onion, chopped
  • 1/3 cup chopped fresh cilantro leaves (divided)
  • 1/2 teaspoon salt
  • 1/2 teaspoon cumin powder
  • 3 medium avocados
  • 3 to 4 tablespoons lime juice (or use the juice from the pepperoncini jar)
  • 1/3 cup chopped pepperoncini’s
  • 2 tomatoes, diced


  1. Put the onion, half of the cilantro, salt, and cumin in a mortar and pestle bowl or a food processor.  Smash or blend until it turns into a paste. 
  2. Scoop the onion paste into a large bowl and add the avocados. Mash to your desired consistency. 
  3. Stir in the rest of the cilantro, the lime juice, pepperoncini, and tomatoes. Taste and season with more salt if desired.


Smashing the onions and cilantro into a paste will give the guacamole more depth of flavor than if you just stir in chopped onions. If you don't have a mortar and pestle you can use a food processor or mash it with a rolling pin.

Guacamole is best when it is made fresh but if you have any leftover sprinkle some lime or lemon juice over the top then press plastic wrap directly onto the guacamole. The plastic wrap needs to touch the surface of the guacamole so air does not come into contact with it.  Store in  the fridge for up to 2 days.
