Tuna Pie in Puff Pastry – Super Easy, Super Tasty

The beauty of this pie lies in its simplicity: it comes together with ingredients that most of us already have in our pantry or fridge. A can of tuna (or even mackerel), a couple of eggs, some tomato passata, and puff pastry are often all you need.

It’s proof that with just a few everyday staples, you can create a dish that’s versatile enough to fit every season.

How I Make It

I begin by gathering all the ingredients: about 250 g of well-drained tuna, a couple of anchovy fillets (optional, but they give wonderful depth to the sauce), diced tomato, scallions, a red bell pepper, and 2 cloves of garlic. I also prepare two hard-boiled eggs and around 120 g of thick tomato passata.

If I have them on hand, I like to add a few capers for extra flavor. For seasoning, I use salt, black pepper, chili flakes or sweet paprika, a little fresh thyme, and just a pinch of sugar to balance the sauce. The puff pastry stays in the fridge until the filling is ready, so it keeps nice and firm.

I start by dicing the tomato, onion, and red bell pepper, then set them aside. Next, I mince the garlic together with the anchovies and thyme until they turn into a kind of paste, and I blend in a tablespoon of tomato paste.

Since I use tuna preserved in olive oil, I save that oil after draining it and add a couple more tablespoons to the pan. In goes the garlic-thyme-anchovy paste, and a few capers, and I let them sizzle gently for about 5 minutes until the oil is fragrant.

Then I add the diced vegetables and let them cook down for about 15 minutes. I season with salt, pepper, paprika (or chili flakes), and a little sugar to balance the flavors. Once the veggies are soft, I stir in the tuna and cook for another 5 minutes.

The passata goes in last, and I let it simmer until the sauce is thick and not watery. Then I add the green part of the scallions.

While the filling cools, I chop the hard-boiled eggs—my trick is to do this with a fork so the pieces stay chunky instead of mushy. I mix them into the filling once it’s cooled completely.

Now it’s time for the pastry! I line a silicone tray with one sheet of puff pastry, spoon in the filling, and cover it with another sheet.

If I have leftover pastry, I like to cut it into the shape of a fish to decorate the top. It bakes for about 20 minutes, or until the crust is golden. I serve it warm, but honestly, it’s just as delicious at room temperature.

One Pie… Many Pies

Fish Variations: Yes, you guessed right, tuna is not the only option, you can make this pie with other fish:

• Mackerel pie
  Use canned mackerel in olive oil instead of tuna for a richer, more intense flavor. Works well with capers and a touch of lemon zest.

• Salmon pie
  Swap tuna for canned or fresh-cooked salmon. Add dill or parsley to the filling for freshness.

• Sardine pie
  Use canned sardines (remove any bones) for a rustic twist. Pair with olives and red onion for a Mediterranean touch.

• Cod pie
  Flake in cooked cod or even salted cod (after desalting). Excellent with extra peppers and a hint of smoked paprika.

Chicken Variation

• Chicken puff pastry pie
  Replace tuna with shredded cooked chicken (great for leftovers or rotisserie chicken). Add mustard or curry powder for extra flavor.

Vegetarian Variation

• Mediterranean veggie pie
  Skip the fish and use diced zucchini, mushrooms, and extra peppers. Add chickpeas or lentils for protein, and optionally crumble in some feta.

Cheesy Twist

• Tuna and cheese pie
  Mix grated cheese (such as kefalotyri, Parmesan, or cheddar) into the filling for a creamier, richer pie.

Fresh Herb Upgrade

• Add chopped parsley, dill, or basil to the filling before baking for a fresher taste.

Make Ahead & Storage

• Prepare the filling in advance
  The tuna mixture can be made up to 2 days ahead and stored in an airtight container in the fridge. Let it cool completely before storing.

• Refrigerate
  Store leftover pie in the fridge, covered or in an airtight container, for up to 3 days.

• Reheat
  Warm slices in the oven at 180°C (350°F) for 10–15 minutes. Avoid microwaving if possible, as it softens the pastry.

• Freezing
  Unbaked pie – Assemble the pie, wrap it tightly in plastic wrap and foil, and freeze for up to 2 months. Bake directly from frozen, adding about 10 extra minutes to the baking time.
