If you’re craving a quick lunch that feels light but still fills you up, these Avocado Tuna Salad Bowls deliver. They’re creamy, crunchy, and bright with lemon—no fussy steps, no hard-to-find ingredients. Everything mixes together in minutes, and you can customize each bowl with add-ins you already have.

It’s the kind of meal that works for meal prep or a last-minute lunch, and it tastes great straight from the fridge. Simple, clean, and genuinely delicious.

Why This Recipe Works

Avocado brings natural creaminess, so you don’t need much mayo—just enough to bind the tuna and add a little richness. Lemon juice and herbs lift the flavors and keep the avocado from browning, while crunchy veggies add texture so every bite feels fresh.

Using canned tuna keeps it affordable and convenient, but the bowl still feels complete thanks to the toppings and greens. It’s balanced with protein, healthy fats, and fiber, which makes it satisfying without being heavy.

What You’ll Need

• 2 cans (5 oz/142 g each) tuna, drained (water-packed or olive oil—your choice)
• 1 large ripe avocado, diced
• 2 tablespoons mayonnaise (or Greek yogurt for a lighter option)
• 1 tablespoon Dijon mustard
• 2 tablespoons lemon juice (plus more to taste)
• 1 small celery stalk, finely diced
• 1/4 small red onion, finely chopped (or 2 scallions, sliced)
• 1 small cucumber, diced
• 2 tablespoons fresh herbs (dill, parsley, or chives), chopped
• 1 tablespoon capers, drained (optional but great)
• Salt and black pepper, to taste
• 2–3 cups mixed greens (spring mix, arugula, or chopped romaine)
• Cherry tomatoes, halved (about 1 cup)
• Cooked grains for serving (optional): quinoa, brown rice, or farro
• Olive oil, for drizzling (optional)

Instructions

1. Prep the base. Add the mixed greens to 2–3 bowls. If using grains, add a warm or room-temp scoop to each bowl.
2. Make the tuna mix. In a medium bowl, combine the drained tuna, mayonnaise, Dijon mustard, lemon juice, celery, red onion, herbs, and capers.

   Stir to combine, then season with salt and pepper. Taste and adjust lemon, salt, and mustard as needed.

3. Add the avocado. Gently fold in the diced avocado so it stays chunky. If your avocado is very soft, fold lightly to keep the texture creamy but not mushy.
4. Assemble the bowls. Spoon the tuna-avocado mixture over the greens and grains.

   Add cucumber and cherry tomatoes around the edges for color and crunch.

5. Finish and serve. Drizzle a little olive oil and an extra squeeze of lemon over each bowl. Crack fresh black pepper on top and serve immediately.

Storage Instructions

Refrigerate the tuna mixture (without greens) in an airtight container for up to 2 days. The lemon helps keep the avocado from browning, but a light press of plastic wrap directly on the surface adds extra protection.

Store the greens, tomatoes, and cucumber separately to keep them crisp. Assemble just before eating.

If you plan to store longer than 24 hours, add the avocado right before serving for best color and texture. Leftovers are safe to eat cold straight from the fridge.

Benefits of This Recipe

• High in protein and healthy fats: Tuna provides lean protein; avocado offers heart-healthy monounsaturated fat.
• Quick and no-cook: Ideal for busy days or hot weather—everything comes together in minutes.
• Balanced and filling: Fiber from veggies and optional grains helps keep you full longer.
• Budget-friendly: Uses pantry staples and flexible produce you may already have.
• Customizable: Easy to adapt for different diets—gluten-free, low-carb, dairy-free.

What Not to Do

• Don’t skip the acid. Lemon juice brightens the flavors and keeps avocado fresh-looking.
• Don’t overmix the avocado. Stir gently to avoid a mushy texture.
• Don’t use watery tuna. Drain well or the salad will be soggy and bland.
• Don’t dress the greens ahead of time. They’ll wilt.

  Add lemon and oil right before serving.

• Don’t overload the mayo. The avocado already adds creaminess; too much mayo can dull the flavors.

Alternatives

• No mayo option: Use Greek yogurt or mashed avocado only. Add a splash of olive oil for richness.
• Protein swaps: Use canned salmon or shredded rotisserie chicken. For vegetarian, try chickpeas or white beans.
• Flavor twists: Add a pinch of cumin and smoked paprika; or go Mediterranean with chopped olives, feta, and oregano.
• Crunch upgrades: Toasted almonds, pumpkin seeds, or crushed pita chips.
• Greens and grain swaps: Kale, spinach, or cabbage slaw; farro, couscous, or cauliflower rice.
• Heat lovers: Stir in sriracha, red pepper flakes, or diced jalapeño.

FAQ

Can I make this ahead for meal prep?

Yes.

Mix everything except the avocado and greens up to 2 days in advance. Add avocado just before eating and assemble over fresh greens for the best texture.

Which tuna is best for this recipe?

Solid or chunk light tuna in water is clean and lean; tuna in olive oil has richer flavor. Albacore is milder and meatier, while skipjack is more budget-friendly.

Use what you like and drain well.

How do I keep the avocado from browning?

Toss it with lemon juice and fold it into the tuna mixture. Press plastic wrap directly on the surface of leftovers. If serving later, add avocado right before eating.

Is there a dairy-free option?

Yes.

Use mayonnaise or mashed avocado only and skip the yogurt. Everything else in the recipe is naturally dairy-free.

Can I use frozen or fresh tuna instead of canned?

You can. Cook fresh tuna to medium, let it cool, then flake it into the mixture.

Keep seasoning the same and adjust lemon and salt to taste.

What can I use instead of celery?

Try diced fennel, bell pepper, or extra cucumber for crunch. Finely chopped pickles also work if you like a tangy bite.

How do I make it low-carb?

Skip the grains and serve over leafy greens or shredded cabbage. Add extra cucumber and avocado to make it more filling.
