What Is Tuna Tartare?

Tuna tartare is a raw tuna appetizer made from finely diced, sushi-grade tuna. Unlike cooked tuna dishes, tartare showcases the delicate texture and natural flavor of raw fish. It’s often seasoned with citrus juice, herbs, olive oil, and savory condiments like capers or soy sauce.

This version leans into Mediterranean-style simplicity with lime, olive oil, and herbs, plus a gentle kick from sriracha—a popular chili garlic sauce you can adjust to your taste.

Ingredients for 3 Servings

All quantities are carefully calibrated to balance flavor and freshness.

400 g (14 oz) Pacific bluefin tuna, sushi-grade, previously frozen and thawed in the fridge
8 g (3 tbsp) fresh chives, finely chopped
6 g (2 tbsp) fresh dill, finely chopped
Zest of 1 lime
15 ml (1 tbsp) fresh lime juice
18 g (1 tbsp heaping) capers, drained and roughly chopped
22 ml (1 tbsp + 1 tsp) extra virgin olive oil
5 ml (1 tsp) sriracha, or more to taste
2–3 g (½ tsp) fine sea salt, or to taste
2 g (½ tsp) ground black pepper
10 g (1 handful) arugula or microgreens, for garnish
4 slices rye bread, lightly toasted, for serving

💡Note on tuna safety: Always use sushi-grade tuna that has been properly frozen and thawed. Ask your fishmonger for sashimi-quality cuts.

Step-by-Step Instructions

1. Prepare the Tuna

Remove any skin or sinew from the tuna. Using a very sharp knife, cut it into thin strips, then dice into small cubes. The cut should be clean, not mashed, to preserve the integrity of the fish.

Pat the tuna gently with a paper towel if there’s excess moisture.

2. Prep the Flavorings

Chop the herbs: Finely mince the chives and dill.
Zest and juice the lime: Avoid bitter white pith.
Chop the capers: Just a few strokes to release flavor without turning them into paste.

3. Combine Everything

In a large glass or stainless steel mixing bowl (chilled if possible), combine:

Diced tuna
Lime zest and juice
Capers
Chopped herbs
Olive oil
Sriracha
Salt and pepper

Use a flexible spatula or spoon to gently fold the ingredients together until the tuna is evenly coated.

For a spicier tartare, increase the sriracha to your liking. Start with 1 tsp, taste, and adjust.

4. Chill Briefly

Cover the bowl and refrigerate for 20 to 30 minutes. This allows the flavors to meld while keeping the tuna raw and fresh. Don’t marinate too long or the citrus will start to “cook” the fish, changing its color and texture.

5. Plate Like a Pro

To make your tartare look as good as it tastes:

Place a metal ring mold in the center of each plate.
Fill with tartare, gently pressing to shape without compressing.
Carefully lift the mold.
Add arugula or microgreens around the tartare.
Serve with toasted rye bread on the side or underneath.

Finish with a drizzle of olive oil and a touch of lime zest for extra brightness.

Pro Tips for Success

Use cold tools: Chill your knife, bowl, and cutting board beforehand.
Taste before serving: Adjust salt, pepper, and heat levels as needed.
Serve immediately after resting: Tartare should be eaten fresh and cold.
Never use a food processor: Only hand-cutting preserves the right texture.
Don’t over-marinate: 30 minutes max to avoid “cooking” the fish with citrus.
