Freezer Friday: It’s My Birthday – So I Made a Fish Pie in Pastry

Freezer Friday: It’s My Birthday – So I Made a Fish Pie in Pastry

It’s my birthday today – and while that might call for something fancy or a night off cooking, I’ve decided to celebrate in true me style: by raiding the freezer and wrapping dinner in pastry.

This week’s Freezer Friday recipe is something a little indulgent, a little comforting, and very much made with what I had on hand.
It’s a hybrid salmon wellington meets fish pie, made with frozen salmon, frozen veg, a creamy herbed sauce, and a sheet of puff pastry to bring it all together. Simple, satisfying, and surprisingly elegant for a meal built from the freezer.


Why This Works for Freezer Friday

  • It clears out those frozen fillets you’ve been saving “for one day.”
  • You can bulk it out with frozen spinach, peas, or leftover cooked veg.
  • It’s easy to double – make one for now, one for later.
  • And frankly, pastry makes everything feel a bit more like a treat.

The Birthday Bake – Recipe

Ingredients

  • 2–3 frozen salmon fillets (thawed or part-frozen is fine)
  • 1 small leek or half an onion, finely sliced
  • 1 cup frozen spinach or peas (or both)
  • 2 tbsp butter
  • 2 tbsp plain flour
  • 1 cup milk
  • ½ tsp Dijon mustard (optional)
  • A handful of fresh herbs – dill or parsley
  • Salt and pepper
  • 1 sheet puff pastry, thawed
  • 1 egg, beaten (for brushing)

Optional Extras

  • Spoon of mashed potato (for extra creaminess)
  • Chopped hard-boiled egg (a nod to a traditional fish pie)
  • Grated cheese (always welcome)

Method

  1. Make the white sauce: Sauté leek/onion in butter until soft. Stir in flour, cook for a minute, then gradually whisk in milk. Add mustard, season, and stir in frozen greens and herbs. Let it cool a little.
  2. Prep the salmon: Cut into chunks if partially frozen, or use whole fillets if easier.
  3. Assemble: On a lined tray or dish, lay out pastry. Spoon some sauce down the centre, layer salmon, top with more sauce. Fold the pastry over and seal. Brush with egg.
  4. Bake at 200°C (fan 180°C) for 30–35 minutes until golden and puffed.
  5. Cool and freeze any extras – or prep a second one while you’re at it.

To Serve

Pair it with a crisp green salad, roasted carrots, or steamed greens from the garden. A glass of wine wouldn’t go astray either – it is my birthday, after all.


Freezer Tips

  • To freeze unbaked: wrap tightly, freeze flat. Bake from frozen with an extra 10–15 minutes.
  • To freeze after baking: cool completely, slice into portions, and freeze for quick lunches or dinners.

So there you have it – a Freezer Friday meal that’s birthday-worthy without the fuss.
It’s warm, filling, and made entirely from things I already had on hand.
Honestly, what more could I want for a birthday dinner?
