Slice the avocados in half lengthwise. Carefully remove the pits. Using a knife, make horizontal and vertical cuts int he avocado, being careful not to cut through the skin. Scoop out the avocado flesh and add to a mixing bowl.
Squeeze the fresh lime juice over the avocado and using a fork, mash the avocado until it reaches the desired consistency.
Stir in the finely diced red onion, jalapeno (optional), chopped cilantro, and season with salt and pepper. Serve immediately or store tightly covered in the refrigerator for 3-4 days. (Note 1)
Transfer the guacamole to an airtight container. Place plastic wrap over the guacamole, pressing the wrap so that's it's touching the surface of the guacamole and blocking exposure to air. Secure the lid and store in the refrigerator for up to 3-4 days.
Make the guacamole right before you want to serve it. Avocados turn brown easily, so it's best not to make it ahead of time. The lime juice is key here - the acid helps prevent the avocado from turning brown.
Customize the flavors to your taste. Adjust the amount of onion, jalapenos, and cilantro based on your personal preference.
Add ins: Stir in chopped tomatoes, cotija or feta cheese, or grilled corn. Get creative with different flavor combos.
