There’s something magical about the way fresh tuna melts in your mouth, especially when it’s prepared as a crudo. Today, I’m excited to share my favorite tuna crudo recipe that combines the buttery richness of sashimi-grade tuna with a bright citrus caper vinaigrette. This dish brings together Italian and Japanese influences, creating a harmonious blend that’s perfect for warm summer evenings or elegant dinner parties.
What is Crudo?
Before we dive into the recipe, let’s understand what makes a crudo special. Unlike ceviche, where seafood is “cooked” in citrus juice, crudo is the Italian approach to serving raw fish. The fish is typically dressed with high-quality olive oil and seasonings just before serving, allowing its natural flavors to shine through.
Selecting Your Ingredients
The Star of the Show: Tuna
When it comes to crudo, the quality of your tuna is paramount. Here’s what I look for:
- Color: Vibrant red with no brown spots
- Texture: Firm and resilient when pressed
- Smell: Clean, oceanic scent with no fishiness
- Grade: Always choose sashimi-grade tuna from a reputable supplier
Essential Ingredients Table
| Ingredient | Quantity | Notes |
|---|---|---|
| Sashimi-grade tuna | 1 pound | Ask for center-cut loin |
| Blood oranges | 2 medium | Plus extra for garnish |
| Lemons | 2 large | Organic preferred |
| Extra virgin olive oil | 1/2 cup | Highest quality available |
| Capers | 3 tablespoons | Drained and rinsed |
| Shallots | 2 medium | Finely minced |
| Fresh herbs | 1/4 cup each | Mixture of chives, basil, and mint |
| Flaky sea salt | To taste | Maldon or Fleur de sel |

Equipment Needed

The Art of Preparation
Preparing the Tuna
- Remove the tuna from refrigeration 30 minutes before slicing
- Pat dry with paper towels
- Using a sharp knife, slice against the grain into 1/4-inch thick pieces
- Arrange on a chilled platter
- Cover with plastic wrap and return to refrigerator
Making the Vinaigrette
The vinaigrette is where this dish truly comes alive. Here’s my tried-and-true method:
- Supreme the blood oranges:
- Cut off the top and bottom
- Remove the peel and pith
- Release segments between membranes
- Reserve juice
- Combine citrus elements:
- 1/4 cup blood orange juice
- 2 tablespoons lemon juice
- Zest of one lemon
- Create the emulsion:
- Whisk juices with minced shallots
- Slowly drizzle in olive oil while whisking
- Add chopped capers
- Season with salt and pepper
Assembly and Presentation
- Remove tuna from refrigerator
- Drizzle with vinaigrette
- Garnish with:
- Fresh herbs
- Microgreens
- Blood orange segments
- Extra capers
- Flaky sea salt
- Fresh cracked pepper
Temperature and Timing
The success of this dish relies heavily on temperature control. Here’s my temperature guide:
| Component | Ideal Temperature | Maximum Hold Time |
|---|---|---|
| Tuna | 38-40°F (3-4°C) | 2 hours |
| Serving Platter | 35-38°F (2-3°C) | N/A |
| Vinaigrette | Room temperature | 4 hours |
Serving Suggestions
I love serving this dish as:
- A sophisticated appetizer for 6-8 people
- Light main course for 4 people
- Part of a seafood tasting menu
- Summer dinner party starter
Accompaniments that work well include:
- Grilled sourdough crostini
- Fresh fennel salad
- Pickled ginger
- Wasabi paste (use sparingly)
Storage and Food Safety
When working with raw fish, food safety is crucial. Follow these guidelines:
| Aspect | Recommendation |
|---|---|
| Storage Temperature | Below 40°F (4°C) |
| Maximum Storage Time | 24 hours |
| Preparation Surface | Sanitized stainless steel |
| Hand Washing | Before and during prep |
| Cross Contamination | Use separate cutting boards |
Common Questions and Answers
Q: Can I make this dish ahead of time?
No, crudo should be prepared and served within 15-30 minutes of assembly. The vinaigrette can be made up to 4 hours ahead.
Q: What’s the best substitute for blood oranges when they’re not in season?
Regular oranges or cara cara oranges work well, though they’ll provide a slightly different flavor profile.
Q: How do I know if my tuna is fresh enough?
Fresh tuna should have a clean ocean smell, bright red color, and firm texture. Always purchase from a trusted seafood supplier.
Q: Can I freeze the tuna and use it later?
While technically possible, I don’t recommend freezing tuna intended for crudo. Fresh is always best for raw preparations.

Troubleshooting Tips
If you encounter any of these common issues:
- Tough tuna: Likely sliced with instead of against the grain
- Bitter vinaigrette: Too much pith included from citrus
- Fishy smell: Tuna isn’t fresh enough – don’t use
- Runny presentation: Didn’t pat tuna dry before slicing
Seasonal Variations
While this recipe is perfect year-round, I like to make these seasonal adjustments:
- Spring: Add fresh pea shoots and mint
- Summer: Include stone fruit like peaches
- Fall: Incorporate pomegranate seeds
- Winter: Use citrus supremes and fennel
Understanding these seasonal nuances helps create a dish that’s always at its peak of flavor and freshness.
Recipe Success Tips
- Keep everything cold until the last moment
- Use the sharpest knife you own
- Don’t overdress the fish
- Season just before serving
- Present on chilled plates
Remember, the key to an exceptional crudo lies in the quality of your ingredients and your attention to detail in preparation. With practice, this dish will become a go-to for impressing guests or enjoying a restaurant-quality meal at home.
