1. Avocado Tuna Salad Recipe (Yield: 6 Servings)

Ingredients

• 15 oz tuna in oil, drained and flaked (about 3 small cans)
• 1 English cucumber, sliced
• 2 large or 3 medium avocados, peeled, pitted, and sliced
• 1 small/medium red onion, thinly sliced
• 1/4 cup cilantro, chopped (about half of a small bunch)
• 2 tbsp lemon juice, freshly squeezed
• 2 tbsp extra virgin olive oil
• 1 tsp sea salt, or to taste
• 1/8 tsp black pepper

Instructions

Prepare the tuna

Start by draining the canned tuna thoroughly to remove excess oil or liquid. Flake the tuna into bite-sized pieces using a fork and place it into a large mixing bowl.

Slice the vegetables

Wash and slice the English cucumber into thin rounds. Thinly slice the red onion and chop the cilantro finely. Then, peel, pit, and slice the avocados. To prevent browning, drizzle a small amount of lemon juice over the avocado slices.

Combine the ingredients

Add the cucumber, avocado, red onion, and cilantro to the bowl with the tuna. Toss the ingredients gently with a large spoon or salad tongs, taking care not to mash the avocado pieces.

Make the dressing

In a small bowl, whisk together the freshly squeezed lemon juice, extra virgin olive oil, sea salt, and black pepper. Taste and adjust the seasoning if needed.

Mix and serve

Pour the dressing over the salad mixture and toss gently until everything is evenly coated. Serve immediately for the freshest flavor and best texture.

Optional presentation

For an elegant touch, serve the salad on a bed of mixed greens or in avocado halves for a beautiful presentation. Garnish with extra cilantro or a lemon wedge for added freshness.

2. Tips for Perfect Avocado Tuna Salad

To make the perfect Avocado Tuna Salad every time, start with high-quality tuna. Tuna packed in olive oil adds a rich flavor and moist texture, making the salad more delicious. If you prefer a lighter option, tuna in water can also be used — just add an extra drizzle of olive oil to balance the flavor.

Use ripe but firm avocados for the best results. They should yield slightly to gentle pressure but not feel mushy. Overripe avocados may make the salad too soft and lose their shape when mixed.

Always use freshly squeezed lemon juice instead of bottled lemon juice for a bright and natural citrus flavor that complements the tuna and avocado perfectly. Lemon juice also helps slow down the browning of avocados, keeping the salad vibrant.

If you want extra crunch, consider adding chopped celery or bell peppers to enhance the texture. For a spicy kick, sprinkle in a pinch of red chili flakes or diced jalapeño.

Lastly, if you plan to make this salad ahead of time, store the components separately — especially the avocado — and combine them just before serving. This helps maintain the freshness and appearance of the dish.

3. Frequently Asked Questions

Can I use canned tuna in water instead of oil?
