Ingredients Method

Ingredients

  

• 2 (5-ounce) cans tuna, drained (albacore or chunk light)
• 1 large ripe avocado
• 2 tablespoons fresh lemon juice (plus more to taste)
• 1 small celery stalk, finely chopped
• 2 tablespoons red onion, finely minced
• 2 tablespoons chopped fresh parsley or cilantro
• 1 teaspoon Dijon mustard
• 1 tablespoon extra-virgin olive oil (optional for silkier texture)
• Salt and black pepper to taste
• Optional mix-ins: 1 tablespoon capers, 1 small dill pickle chopped, 1/4 teaspoon garlic powder, red pepper flakes, or everything bagel seasoning
• For serving: whole-grain bread, crackers, romaine or butter lettuce leaves, cucumber slices, or mixed greens

Method

 

1. Prep your mix-ins. Finely chop the celery, red onion, and herbs. Smaller pieces blend better and give even flavor.
2. Mash the avocado. In a medium bowl, scoop out the avocado and mash it with a fork until mostly smooth with a few small chunks.
3. Add flavor boosters. Stir in the lemon juice, Dijon mustard, and olive oil (if using). Season with a pinch of salt and pepper.
4. Fold in the tuna. Add the drained tuna, breaking it up gently with a fork. Fold until coated but not overmixed to keep a pleasant texture.
5. Stir in crunch and herbs. Mix in the celery, red onion, and parsley or cilantro. Add any optional mix-ins like capers or a pinch of garlic powder.
6. Taste and adjust. Add more lemon, salt, or pepper as needed. If it’s too thick, a splash of olive oil or an extra squeeze of lemon loosens it up.
7. Serve your way. Spoon onto toast, tuck into lettuce wraps, top a salad bowl, or serve with cucumber rounds and crackers.

Storage Instructions

Best same day: Avocado will slowly brown, even with lemon, so this is at its peak right after mixing. Leftovers are still tasty.

Short-term storage: Transfer to an airtight container. Press plastic wrap directly on the surface to limit browning.

Refrigerate up to 1–2 days.

Meal prep tip: Mix the tuna, celery, onion, and seasonings ahead. Add mashed avocado and lemon right before eating for the freshest color and flavor.

Do not freeze: The texture becomes watery and grainy after thawing.

Health Benefits

• High-quality protein: Tuna provides lean protein to help keep you full and support muscle maintenance.
• Healthy fats: Avocado offers heart-healthy monounsaturated fats that support satiety and nutrient absorption.
• Omega-3s: Tuna contains omega-3 fatty acids, which support brain and heart health.
• Fiber and micronutrients: Avocado and veggies add fiber, potassium, folate, vitamins C and K, and antioxidants.
• Lower in mayo and sugar: Skipping traditional mayo keeps this salad lighter without sacrificing creaminess.

Common Mistakes to Avoid

• Using underripe avocado: Hard avocados won’t mash well and won’t coat the tuna. Choose one that yields slightly to gentle pressure.
• Skipping acid: Lemon juice keeps flavors bright and helps slow browning.

  Without it, the salad can taste flat.

• Overmixing: Stir just until combined to maintain texture. Overmixing can make the salad dense.
• Too much liquid: If your tuna is very wet, press it gently in a sieve after draining to avoid a watery salad.
• Under-seasoning: Tuna and avocado both need salt and pepper. Taste at the end and adjust.

Variations You Can Try

• Mediterranean: Add chopped cucumber, cherry tomatoes, Kalamata olives, and a sprinkle of feta.

  Use fresh dill and a splash of red wine vinegar.

• Spicy Chipotle: Mix in chipotle chili powder or minced chipotle in adobo, corn kernels, and cilantro. Finish with lime juice instead of lemon.
• Herby Crunch: Add chopped dill, chives, and sliced radishes. Top with toasted sunflower seeds for extra texture.
• Apple and Walnut: Fold in small diced green apple and toasted walnuts.

  The sweet-crunch combo is great on whole-grain toast.

• Greek Yogurt Boost: For extra protein, replace 1/4 of the avocado with plain Greek yogurt. It stays creamy with a subtle tang.
• No-Tuna Option: Swap tuna for canned salmon or chickpeas (roughly mashed) for a pescatarian or vegetarian twist.

FAQ

Can I use fresh tuna instead of canned?

Yes, but cook it first. Sear or poach fresh tuna, let it cool, and flake it.

Canned tuna is more convenient and gives that classic texture.

What type of canned tuna is best?

Albacore is meaty and mild, while chunk light is softer with a stronger tuna flavor. Choose what you prefer. Look for tuna packed in water to control the fat and texture.

How do I keep the avocado from browning?

Use plenty of lemon juice and store with plastic wrap pressed directly on the surface.

A thin film of olive oil on top also slows oxidation.

Is this recipe dairy-free and gluten-free?

Yes, the salad itself is dairy-free and gluten-free. If serving with bread or crackers, choose gluten-free options if needed.

Can I add mayonnaise?

Absolutely. A tablespoon or two of mayo can make it extra creamy.

You can also use a half-and-half mix of avocado and mayo.

What can I use instead of celery?

Try diced cucumber, bell pepper, or jicama for crunch. Keep the pieces small so they mix smoothly.

How can I make it spicier?

Add minced jalapeño, red pepper flakes, hot sauce, or a pinch of cayenne. Start small and adjust to taste.

Is it safe to meal prep with tuna?

Yes.

Keep it refrigerated in an airtight container and eat within 1–2 days. For best results, mix in the avocado right before serving.

What should I serve it with?

It’s great on toast, stuffed into pita, rolled in tortillas, scooped into lettuce cups, or spooned over a big salad. Crackers and sliced cucumbers make easy dippers.

Can I make it low-carb or keto-friendly?

Yes.

Serve it on lettuce wraps, with cucumber slices, or over salad greens. Skip bread and high-carb crackers.
