Bright, citrusy, and impossibly fresh, this ceviche is the kind of dish that makes a serious impression with very little effort. Sushi-grade tuna gets a quick cure in a punchy blend of lime and orange juice with freshly grated ginger, turning out tender and flavorful with just the right amount of zing. The short refrigerator cure — only about 12 to 15 minutes — keeps the fish silky at the center rather than tough, which is the detail that separates a great ceviche from a mediocre one. Crisp English cucumber, scallion greens, cilantro, and creamy avocado round everything out, making each bite feel balanced and vibrant. A finishing drizzle of olive oil and a hit of lime zest tie it all together beautifully. Every single ingredient here is naturally free from tree nuts, so there's no need to scrutinize labels or swap anything out — it just works as written. Serve it immediately after folding in the avocado for the best texture and color.

Ingredients

4 servings

1 lb sushi-grade tuna, cut into ½-inch cubes
½ cup fresh lime juice (from about 4 limes)
2 tbsp fresh orange juice
1 tsp fresh ginger, finely grated
½ tsp fine sea salt
1 medium english cucumber, seeded and diced small
3 scallions (green tops only), thinly sliced
1 ripe avocado, diced
¼ cup fresh cilantro leaves, roughly chopped
2 tbsp fresh mint leaves, roughly chopped (optional)
1 tbsp extra-virgin olive oil
1 tsp lime zest

Instructions

1
In a large mixing bowl, combine the tuna cubes, lime juice, orange juice, grated ginger, and sea salt. Toss gently to coat every piece of tuna evenly.
2
Cover the bowl and refrigerate for 12–15 minutes, until the tuna cubes are opaque on the outside but still have a slightly translucent, tender center — they should feel firm to a gentle press but not rubbery.
