Ingredients
Step-by-Step Method
Drain and Press the Tuna
Open both cans of tuna and drain them through a fine sieve. Transfer the tuna to a clean paper towel and press firmly with another paper towel to remove as much moisture as possible. This step is what most recipes skip — residual liquid turns the filling watery within minutes. Repeat the press once more if the tuna still feels wet.
Prep the Avocados
Halve each avocado lengthwise and remove the pit. Use a large spoon to scoop out a small additional amount of flesh from the center cavity, creating a deeper bowl shape. Set the scooped flesh aside — it can be mixed into the tuna filling or mashed separately as extra. Score the remaining avocado flesh lightly with a knife without cutting through the skin.
Mix the Tuna Filling
Combine the pressed tuna, Greek yogurt or mayonnaise, Dijon mustard, lemon juice, diced celery, and diced red onion in a mixing bowl. Stir until evenly combined. The mixture should hold its shape on a spoon — if it looks loose, add another half tablespoon of yogurt. Season with salt at this point, right before filling, to avoid drawing out moisture.
Stuff the Avocados
Spoon the tuna filling generously into each avocado half, pressing it slightly into the cavity so it sits above the rim. Divide evenly across all four halves. The filling should be compact enough that it doesn't fall off when you pick up the avocado half. If the avocado halves feel unstable on the plate, trim a thin slice off the rounded underside to create a flat base.
Garnish and Season Check
Squeeze a small additional amount of lemon juice over the filled avocados to keep them from browning. Add a light sprinkle of black pepper or chili flakes if you want heat. Tear fresh coriander leaves and place them directly on top of the filling — don't chop them fine, larger pieces hold up better visually and in flavor. Taste one bite before serving and adjust salt if needed.
Serve Immediately
Plate the stuffed avocado halves on a bed of arugula or serve alongside sliced cherry tomatoes. Eat within 20-30 minutes of assembling for the best texture — the avocado starts to oxidize around the cut edges after that. Serve at room temperature, not cold from the fridge, as chilled avocado mutes the flavor of the filling.
Frequently Asked Questions
Do I need to cook anything for this recipe?
No. This is a no-cook recipe with 0 minutes of cook time. You drain and press the tuna, mix the filling, and stuff the halved avocados, so nothing is heated at any stage.
How do I stop the tuna filling from turning watery?
Drain both cans through a fine sieve, then press the tuna between paper towels to remove as much moisture as possible, repeating the press if it still feels wet. Residual liquid is what turns the filling watery within minutes. Season with salt right before filling rather than earlier, so the salt does not draw out more moisture.
How do I keep the avocado from browning?
Squeeze fresh lemon juice into the filling and a little more over the filled halves. The lemon slows oxidation, but the stuffed avocados are still best eaten within 20 to 30 minutes of assembling, before the cut edges start to brown.
Should I serve this cold or at room temperature?
Serve at room temperature rather than straight from the fridge. Chilled avocado mutes the flavor of the filling, so let the halves come up from cold before serving on a bed of arugula or alongside cherry tomatoes.
