Step-by-Step Instructions

1. Combine Ingredients

In a large mixing bowl, add the tuna, red onion, celery, cucumber, and parsley. Gently mix to combine the ingredients.

Drizzle the mixture with avocado oil and lemon juice. Season with kosher salt and black pepper. Stir everything together until well combined.

4. Adjust & Serve

Taste and adjust the seasoning if needed. Serve immediately or refrigerate for later.

Serving Suggestions

This salad can be enjoyed in various ways, making it suitable for different meals and preferences. Here are some of the best ways to serve it:

1. On Its Own

Enjoy a bowl of avocado tuna salad as a light and refreshing meal. It’s perfect for a quick lunch or dinner when you want something filling but not heavy.

2. In Lettuce Wraps

For a low-carb, gluten-free option, scoop the salad into romaine, butter, or iceberg lettuce leaves. The crisp texture of the lettuce contrasts nicely with the creamy tuna mixture.

3. As a Sandwich

Spread the tuna salad between two slices of toasted whole-grain, sourdough, or keto bread for a satisfying sandwich. Add extra toppings like sliced tomatoes or cucumbers for more texture.

4. With Crackers or Rice Cakes

Serve the salad with whole-grain crackers, almond crackers, or rice cakes for a crunchy, bite-sized snack. This is a great way to enjoy it as an appetizer or light meal.

5. Over a Bed of Greens

Transform this dish into a full salad by placing it on top of mixed greens, arugula, or spinach. Drizzle with extra lemon juice and olive oil for added freshness.

6. Stuffed in Avocado Halves

For an extra avocado boost, scoop the salad into halved avocados. This not only enhances the creamy texture but also makes for an elegant presentation.

7. With Pita or Flatbread

Use whole-wheat pita, naan, or low-carb flatbread as a base to create a tuna salad wrap or an open-faced sandwich. Add sliced radishes, cucumbers, or sprouts for extra crunch.

8. In a Stuffed Bell Pepper

For a colorful and nutritious option, fill halved bell peppers with the tuna salad. This adds a natural sweetness and crunch while keeping the meal low in carbs.

Common Mistakes to Avoid

While this recipe is simple, a few common mistakes can affect the taste and texture. Here’s what to watch out for:

1. Over-Mashing the Avocado

If you prefer a chunkier texture, avoid over-mashing the avocado. Mash it lightly so that some pieces remain intact, adding more dimension to the salad.

2. Using Dry Tuna

Canned tuna comes in both oil-packed and water-packed varieties. If using water-packed tuna, make sure it’s well-drained but not overly dry. Adding a little extra avocado oil or olive oil can help maintain a smooth consistency.

3. Not Draining the Tuna Properly

Excess liquid from the tuna can make the salad too watery. To prevent this, drain the tuna thoroughly before mixing it with the other ingredients.

4. Skipping the Lemon Juice

Lemon juice not only adds a bright, tangy flavor but also helps prevent the avocado from browning too quickly. If you plan to store the salad, don’t skip this step.

5. Overloading with Salt

Since tuna has a natural saltiness, start with a small amount of kosher salt and adjust to taste. Adding too much at once can make the salad overly salty.

6. Using Unripe Avocados

Unripe avocados are difficult to mash and won’t create the creamy texture needed for this recipe. Choose avocados that are slightly soft but not overly mushy.

7. Not Chilling Before Serving (Optional)

While the salad can be eaten immediately, chilling it for 15-20 minutes can help the flavors meld together for an even better taste.

8. Adding Too Many Ingredients

While additional veggies can enhance the salad, adding too many can overpower the tuna and avocado. Stick to a balanced mix of crunchy and soft ingredients.

Best Side Dishes for Avocado Tuna Salad

Pairing your creamy avocado tuna salad with the right side dish can enhance the overall meal. Here are eight great options:

1. Kale Caesar Salad

A crisp, garlicky kale Caesar salad adds a flavorful contrast to the creamy tuna salad. The crunch from the kale pairs well with the softness of the avocado.

2. Roasted Sweet Potatoes

For a healthy carb option, serve the salad with roasted sweet potato slices. Their natural sweetness complements the savory tuna salad.

3. Cucumber & Tomato Salad

A simple cucumber and tomato salad with olive oil and vinegar keeps the meal light and refreshing. This side dish adds extra hydration and a burst of fresh flavor.

4. Zucchini Noodles

For a low-carb alternative to pasta, serve the tuna salad alongside zucchini noodles. Drizzle with a little olive oil and lemon juice for a light and satisfying meal.

5. Garlic Parmesan Roasted Asparagus

Roasted asparagus with garlic and Parmesan adds a savory, slightly crispy texture that pairs beautifully with the creamy avocado tuna salad.

6. Avocado Fries

If you love avocado, try baking avocado slices with a crispy almond flour coating. These avocado fries add crunch and pair well with the creamy tuna mixture.

7. Cauliflower Rice

For a low-carb, grain-free option, serve the tuna salad with lightly seasoned cauliflower rice. It absorbs flavors well and makes the meal more filling.

8. Soup

A warm bowl of tomato or butternut squash soup balances out the cold, creamy tuna salad, making it a comforting meal.

Recipe Tips for the Best Avocado Tuna Salad

1. Use High-Quality Tuna

Choose wild-caught, sustainable tuna for the best flavor and nutrition. Tuna packed in olive oil tends to have a richer taste, but water-packed tuna works well if drained properly.

2. Choose the Right Avocados

Select ripe avocados that are soft but not mushy. If the avocados are too firm, they will be difficult to mash and won’t blend smoothly into the salad.

3. Add Extra Crunch if Desired

If you like a crunchier texture, consider adding chopped bell peppers, shredded carrots, or slivered almonds. These ingredients provide additional layers of flavor and texture.

4. Balance the Flavors

Since canned tuna has a natural saltiness, always start with less salt and add more as needed. The lemon juice helps balance the flavors, so don’t skip it.

5. Keep It Creamy

If your salad seems too dry, add an extra drizzle of avocado oil or olive oil. You can also mix in a little more mashed avocado for a richer texture.

6. Customize the Seasoning

This recipe is flexible. Try adding:

• Red pepper flakes or diced jalapeño for a spicy kick.
• Garlic powder or minced garlic for deeper flavor.
• Dijon mustard for an extra tangy taste.

7. Chill Before Serving for Better Flavor

While the salad can be eaten immediately, letting it sit in the refrigerator for 15-20 minutes allows the flavors to meld together for a more developed taste.

Storage & Reheating Instructions

How to Store Avocado Tuna Salad

Proper storage is key to keeping this salad fresh:

✔ Refrigerator: Store the salad in an airtight container for up to 3 days.
✔ Prevent Browning: The lemon juice helps, but placing plastic wrap directly on the surface of the salad minimizes oxidation.
✔ Avoid Freezing: Avocado doesn’t freeze well, and the texture will become grainy and watery after thawing.

How to Keep Avocado from Browning

Avocados naturally turn brown when exposed to air. Here are some ways to slow down the process:

• Use Extra Lemon Juice: The acidity in lemon juice helps prevent oxidation.
• Press Plastic Wrap Against the Salad: This creates a barrier between the avocado and air.
• Store in an Airtight Container: Less air exposure means slower browning.

Can You Make This Salad Ahead of Time?

Yes, but for the freshest taste, it’s best to prepare it no more than 24 hours in advance. If making ahead, add a little extra lemon juice to keep the avocado from browning.
