Ingredients
- Avocados: Go for mini ripe but firm avocados so they hold their shape when mixed. Soft ones can turn mushy too quickly. Love avocados? Try our Blackened Shrimp and Avocado Salad.
- Tomato: Beefsteak is our top choice for their juicy, meaty texture and natural sweetness. If they’re extra ripe, they add even more flavor.
- Red Onion: A little goes a long way! It adds crunch and a sharp bite that balances the creamy avocado. If you want a milder taste, soak the slices in cold water for 10 minutes.
- Cilantro and Oregano: This gives the salad a fresh Mexican flavor. If you’re not a cilantro fan, parsley or basil would make a great substitute.
- Dressing (Olive Oil, Lemon Juice, Salt & Pepper): The dressing brightens the flavors and keeps the avocado from browning.

Substitutions & Variations

- Cilantro: Parsley or basil will make a good substitute.
Storage
This salad is best enjoyed fresh but can be stored in an airtight container in the refrigerator for up to 24 hours. To prevent the avocado from browning, squeeze extra lemon juice over the top before storing.
Recipe FAQs
To keep avocado from browning, toss it with lemon or lime juice before adding it to the salad. The acidity helps slow oxidation, keeping the avocado fresh and vibrant. Storing the salad with plastic wrap pressed directly against the surface also minimizes air exposure.
A simple olive oil and lemon dressing keeps it fresh and light, but you can also use balsamic vinaigrette for a different flavor. For a creamy option, mix Greek yogurt with lime juice and add garlic.
To prevent excess liquid, seed the tomatoes before chopping and add salt just before serving to keep the ingredients from releasing too much moisture. Using firm avocados and tossing the salad gently also helps maintain texture.
