Tuna and Farro Mediterranean Salad
Chewy farro tossed with flaked tuna, halved cherry tomatoes, diced cucumber, kalamata olives, red onion and crumbled feta in a bright lemon, olive oil and oregano dressing finished with fresh parsley.
Why You'll Love This Recipe
This is a hearty grain salad that works as a make-ahead lunch you can pack and eat cold, no reheating required. It suits anyone who wants a filling midday meal that leans on pantry tuna and a cooked grain rather than a sandwich, and it holds up well in a lunch bag or in the fridge for a few days, which makes it friendly for people cooking for one or batching several meals at once.
The dish works because the farro is dressed while it is still slightly warm, or at least freshly cooled, so the porous grains drink in the lemon juice and oregano instead of leaving the dressing pooled at the bottom of the bowl. Flaking the tuna into large pieces rather than mashing it keeps distinct bites of fish against the chew of the grain, and the salty olives and feta season the whole bowl so you need very little added salt. The raw red onion and cucumber add sharp, cooling crunch that keeps each forkful from feeling heavy.
A substantial amount of protein from the tuna and feta meets a whole grain that brings real chew and staying power, so the meal holds you through the afternoon rather than fading an hour later. The tomatoes and cucumber add water and freshness, the olive oil makes it feel rich, and the lemon keeps it bright, so it eats as a complete meal in one bowl instead of a side that needs something alongside it.
Ingredients
- 20 oz tuna in water, drained
- 2 1/2 cups cooked farro
- 1 1/2 cups cherry tomatoes, halved
- 1 cucumber, diced
- 1/2 cup kalamata olives, halved
- 3/4 cup crumbled feta
- 1/2 small red onion, thinly sliced
- 4 tbsp parsley, chopped
- 3 tbsp lemon juice
- 2 tbsp olive oil
- 1 tsp dried oregano
Instructions
- Cook the farro: Rinse the farro under cool water, then simmer it in a pot of water until the grains are tender but still pleasantly chewy, about 25 to 30 minutes. Drain well in a colander and spread it out to cool to room temperature so it does not steam and turn mushy.
- Prep the vegetables: While the farro cools, halve the cherry tomatoes, dice the cucumber into bite-sized pieces, halve the kalamata olives, thinly slice the red onion, and roughly chop the parsley. Slice the onion as thin as you can manage, and if raw onion tends to shout, drop the slices into cold water for five minutes and drain them well.
- Make the dressing: In a large bowl, whisk together the lemon juice, olive oil, and dried oregano for about twenty seconds, until the mixture looks slightly thickened and blended. Crush the oregano between your fingers as it goes in, which wakes up oils that have gone quiet sitting in the jar.
- Toss the base: Add the cooled farro, tomatoes, cucumber, olives, and red onion to the bowl and toss until everything is evenly coated in the dressing. Doing this at room temperature rather than while the grain is still warm is what keeps the cucumber crisp and stops the tomatoes going slack.
- Fold in the tuna: Drain the canned tuna well, flake it into large pieces with a fork, and fold it into the salad along with the chopped parsley, stirring gently so the tuna keeps some of its texture rather than breaking down into paste.
- Finish and rest: Sprinkle the crumbled feta over the top and let the salad sit for 5 minutes so the grains soak up the lemon and oregano before serving. If you are building it ahead for lunches, hold the feta and the parsley back and add them at the table.
Variations
- Swap the grain: Use cooked pearl barley or wheat berries in place of the farro for a similar chew; both take dressing well and still contain gluten.
- Make it grain-free: Trade the farro for cooked and cooled quinoa, which removes the gluten and gives a lighter, fluffier texture while keeping the salad filling.
- Add more vegetables: Fold in diced roasted red pepper or a handful of baby spinach for extra color and volume without changing the character of the dressing.
- Herb it up: Stir in chopped fresh dill or mint along with the parsley for a greener, more aromatic finish that plays off the lemon.
- Swap the fish: Replace the canned tuna with drained canned salmon or cooked, flaked white fish for a different flavor while keeping it a seafood dish.
Storage & Leftovers
Stored in an airtight container in the refrigerator, this salad keeps well for up to three to four days. The flavor actually improves after the first several hours as the farro continues to absorb the lemon and oregano, though the cucumber will soften and give off a little water over time.
This dish is meant to be eaten cold or at room temperature, so there is no reheating step. If it has been in the fridge and tastes flat, let it sit on the counter for 10 to 15 minutes to take the chill off, then brighten it with a fresh squeeze of lemon and a little more chopped parsley before eating.
To make it ahead, cook and dress the farro with the tomatoes, olives and onion and refrigerate that base, but hold off folding in the tuna, cucumber and feta until the day you plan to serve. That keeps the tuna from breaking down, the cucumber crisp, and the feta from dissolving into the grains.
Notes & Tips
- Choose the tuna: Solid or chunk tuna packed in water flakes into meatier pieces than flaked-style cans; drain it firmly by pressing the lid against the fish so the dressing is not watered down.
- Cook the farro right: Semi-pearled or pearled farro cooks faster and softer, while whole-grain farro stays chewier and takes longer, so taste a grain near the end and pull it while it still has bite.
- Tame the onion: If raw red onion is too sharp for you, soak the slices in cold water for about 10 minutes and pat them dry before adding, which mellows the bite without losing the crunch.
- Salt with care: The olives, feta and canned tuna all bring salt, so taste the finished salad before adding any, and lean on extra lemon or oregano to lift the flavor instead.
- Double the batch: This salad scales up easily for meal prep; cook a large pot of farro at once and build bowls through the week, adding the feta and cucumber fresh each day for the best texture.
- Serve it well: Pile it onto a bed of greens or scoop it into a halved tomato or bell pepper to turn a bowl into more of a plated meal, or wrap it in warm flatbread for a portable lunch.
Nutrition & Mindful Eating
- Grain, fish and vegetables are dressed as one thing here. The farro soaks up the lemon and oil, the tuna spreads its savoriness through the bowl, and the tomato and cucumber keep releasing juice as you eat.
- Farro cooks up chewy and springy, every kernel staying distinct rather than going soft, and that texture along with the fiber in it is what gives a cold grain salad its real staying power.
- Feta and olives are the salt in this dish, one crumbling and milky, the other briny and firm, and the olives carry the same kind of fat as the oil they were cured in.
- Tuna broken into large flakes sits in pieces you can actually find, firm and mild against the soft grain, and it brings the protein and omega-3 fats that turn a bowl of grain into lunch.
- Tomato and cucumber keep everything cold and wet, raw onion runs sharp underneath, and parsley and dried oregano crushed between your fingers release the dusty, faintly bitter smell that makes this salad recognizable.
- As you eat, chase a piece of feta and a bit of tomato onto the same fork as the farro, and let the chewing this salad asks for set a pace slow enough to notice the bowl doing its job.
Frequently Asked Questions
Can I make this salad ahead of time?
Yes, and it is one of its strengths. The dressed farro base holds and improves overnight. For the best texture, wait to fold in the tuna, cucumber and feta until the day you serve, since the cucumber softens and the feta dissolves into the grains over time.
Do I have to serve it cold?
It is designed to be eaten cold or at room temperature, so there is no reheating involved. If it has been in the fridge, let it sit out for 10 to 15 minutes and refresh it with a squeeze of lemon before eating.
My farro turned out mushy. What happened?
Most often the grain was cooked too long or not drained and cooled well, so it kept steaming. Simmer just until the farro is tender with a little chew, drain it thoroughly, and spread it out to cool before dressing.
The salad tastes bland. How do I fix it?
Because the tuna, olives and feta already bring salt, the usual fix is not more salt but more acid and herb. Add a fresh squeeze of lemon juice and a pinch more dried oregano, toss, and let it sit a few minutes before tasting again.
