What Ingredients You Will Need

This recipe uses fresh, high-quality ingredients to create a stunning flavor and texture combination. Here’s everything you’ll need:

• Sushi-grade tuna steak: Aim for a thick, fresh cut (about 8 ounces).
• Puff pastry: Store-bought works perfectly; just make sure it’s thawed before using.
• Egg yolk: For brushing the pastry to achieve that golden finish.
• Sesame seeds: Optional, but they add a lovely nutty crunch to the crust.
• Dijon mustard: Adds a tangy layer that complements the tuna’s richness.
• Spinach leaves: Lightly sautéed, they provide a fresh, earthy flavor.
• Shallots: Finely diced for a subtle sweetness.
• Butter: For sautéing the spinach and shallots.
• Salt and pepper: To season the tuna and veggies.

If you’re feeling adventurous, you can even add a thin layer of mushroom duxelles under the tuna for extra depth of flavor. Don’t worry if you’re missing an ingredient or two—this recipe is easy to adapt!

Equipment Needed

• Non-stick skillet: Essential for searing the tuna without sticking.
• Baking sheet: To bake your Wellington to golden perfection.
• Pastry brush: For applying the egg wash evenly.
• Sharp knife: To trim the pastry and slice the finished Wellington.
• Rolling pin: If your puff pastry needs a little extra rolling.

No fancy equipment is required for this recipe, but if you’re missing a pastry brush, you can use a clean paper towel to apply the egg wash. A cast-iron skillet works beautifully for searing the tuna, but any heavy-bottomed pan will do the trick.

Preparation Method

1. Prepare the tuna: Pat the tuna steak dry with paper towels and season generously with salt and pepper. Heat a non-stick skillet over medium-high heat, add a splash of oil, and sear the tuna for about 30 seconds on each side. You just want a light crust—don’t cook it all the way through.
2. Sauté the spinach and shallots: In the same skillet, add a small knob of butter and sauté finely diced shallots until they’re soft and fragrant. Add the spinach leaves and cook until wilted. Remove from heat and let cool.
3. Roll out the pastry: On a lightly floured surface, roll out your puff pastry into a rectangle large enough to wrap the tuna completely.
4. Assemble the Wellington: Spread a thin layer of Dijon mustard onto the pastry. Spoon the cooled spinach mixture over the mustard, spreading it evenly. Place the seared tuna in the center and gently wrap the pastry around it, sealing the edges with a bit of egg yolk.
5. Brush and garnish: Brush the outside of the pastry with egg yolk to ensure a golden color. Sprinkle with sesame seeds if you like.
6. Bake: Preheat your oven to 400°F (200°C). Place the Wellington on a parchment-lined baking sheet and bake for 15-20 minutes, or until the pastry is golden and puffed.
7. Rest and slice: Allow the Wellington to rest for 5 minutes before slicing. This helps the pastry stay crisp and the tuna retain its juices.

Pro tip: If your pastry seems too soft to handle, chill the assembled Wellington in the fridge for 10 minutes before baking.

Cooking Tips & Techniques

• Don’t overcook the tuna: The beauty of this dish lies in the rare center of the tuna. A quick sear is all you need.
• Keep the puff pastry cold: Warm pastry can become sticky and hard to work with. Chill it if it starts to soften.
• Seal the edges properly: Use egg yolk to glue the pastry edges together to prevent leaks while baking.
• Let it rest: Resting the Wellington ensures the juices stay inside the tuna and the pastry remains crisp.

These tips have saved me many times while testing this recipe! Trust me, follow these tricks, and your Tuna Wellington will turn out flawless.

Variations & Adaptations

• Gluten-free option: Use gluten-free puff pastry for a celiac-friendly version.
• Asian-inspired twist: Swap the Dijon mustard for wasabi mayo and add a sprinkle of furikake seasoning.
• Vegetarian idea: Replace the tuna with marinated tofu or a thick slice of roasted eggplant.
• Seasonal touch: Incorporate sautéed mushrooms or caramelized onions in the filling for a wintery vibe.

One of my favorite variations is adding a touch of miso paste to the spinach mixture for an extra umami boost. Feel free to experiment and make this recipe your own!

Serving & Storage Suggestions

Serve the Tuna Wellington warm, sliced into thick pieces that showcase the beautiful layers. Pair it with a crisp green salad, roasted veggies, or even a light citrusy sauce to complement the tuna’s richness. A glass of chilled white wine or champagne is the perfect accompaniment.

For leftovers, wrap the Wellington tightly in foil and store it in the fridge for up to 2 days. Reheat in a 350°F (175°C) oven for about 10 minutes to revive the pastry’s crispness. Avoid microwaving, as it can make the pastry soggy.
