Italian Tuna and Brown Rice Salad, or Riso e Tonno, is a simple, flavorful dish that makes a terrific make-ahead lunch, meal-prep option, or portable meal for busy days. Built from pantry staples like canned tuna, cooked brown rice, capers and high-quality olives, this salad is brightened with lemon juice and balanced with a touch of olive oil. It’s hearty yet light, and it tastes even better after the flavors have melded in the refrigerator.

Italian Tuna and Brown Rice Salad (Riso e Tonno)
This salad is inspired by the classic Italian riso e tonno: a satisfying, no-fuss combination of rice and tuna that’s perfect straight from the fridge. Using brown rice adds whole-grain texture and a nutty flavor, while tuna packed in olive oil gives a richer mouthfeel than water-packed tuna. Capers and black olives contribute briny notes that lift the dish, and a squeeze of fresh lemon keeps the flavors bright.
If you prefer a sandwich, this mixture also makes a delicious filling for a light tuna sandwich or wrap. It’s versatile: serve it chilled on its own, toss it with a bed of greens, or spoon it into pita pockets for a portable lunch.
Why this version works
Early tests showed that the tuna choice and quality of olives make a real difference. Tuna packed in olive oil contributes flavor and moisture, so reserve a little of that oil to dress the salad. If you only have tuna packed in water, it will still work—just add a touch more olive oil to compensate. Likewise, higher-quality black olives add depth, but common canned olives are fine when needed.
Tips
- Drain the tuna thoroughly and reserve a tablespoon of the oil for the dressing if using oil-packed tuna.
- Allow the salad to rest in the refrigerator for at least an hour or overnight — the flavors meld and the salad tastes better the next day.
- Substitute ingredients to suit what you have on hand: canned tuna in water, different mixed vegetables, or green olives can be used, but the taste will vary slightly.
Ingredients
- 2 cans (about 4 oz each), drained — premium canned yellowfin tuna in olive oil (reserve a little oil)
- 1 cup cooked and cooled brown rice
- 8 oz frozen mixed vegetables, cooked and cooled
- 1/4 cup good-quality sliced black olives, chopped if desired
- 2 tbsp drained capers, plus 1 tbsp caper brine
- 1/4 cup chopped red bell pepper
- Juice of 1/2 lemon
- 1/2 tbsp olive oil (use some of the reserved oil from the tuna if available)
- Salt and freshly ground black pepper, to taste
Instructions
- Drain the tuna very well and set aside about a tablespoon of the oil if your tuna is packed in oil.
- In a large bowl, combine the cooked and cooled brown rice, drained tuna, mixed vegetables, sliced olives, capers and chopped red bell pepper. Break up the tuna into bite-sized pieces as you mix.
- Add one tablespoon of the caper brine, the juice of half a lemon and the 1/2 tablespoon of olive oil. If you reserved tuna oil, use that in place of some or all of the olive oil. Toss everything gently until evenly combined.
- Taste and adjust seasoning with salt and pepper. If the salad tastes dry, add a splash more olive oil or a little more lemon juice for brightness.
- Cover and refrigerate for at least an hour to allow the flavors to meld. This salad keeps well for several days refrigerated in an airtight container.
Serving suggestions and variations
Serve the salad chilled as a hearty lunch on its own, or spoon it over a bed of mixed greens. It also works as a stuffing for tomatoes, in pita pockets, or as a topping for crostini. For a creamier texture, stir in a tablespoon of plain yogurt or a light mayonnaise substitute. For extra freshness, add chopped parsley or a few halved cherry tomatoes just before serving.
Storage
Store in an airtight container in the refrigerator for up to 3–4 days. Because this salad contains cooked rice and seafood, keep it chilled and discard if left out at room temperature for more than two hours.
