Ingredients

Scale

TUNA MORNAY

  • 500 g (1 lb 2 oz) conchiglioni (giant pasta shells, or any other pasta you like)
  • 100 g (3½ oz) unsalted butter
  • 2 tsp freshly grated garlic
  • ⅓ cup (50 g) plain (all-purpose) flour
  • 3½ cups (875 ml) full-cream (whole) milk
  • 2 cups (90 g) baby spinach
  • 1 cup (155 g) frozen peas
  • 425 g (15 oz) canned tuna in olive oil, drained (see note 1)
  • Zest and juice of 1 lemon (about 3 tbsp of juice)
  • 1 cup (125 g) grated cheddar or other similar cheese
  • ½ cup (50 g) finely grated parmesan
  • 1½ tsp sea salt flakes
  • ¼ tsp cracked black pepper

PANKO TOPPING

  • ½ cup (60 g) grated cheddar
  • ¼ cup (25 g) finely grated parmesan
  • 1 cup (60 g) panko breadcrumbs
  • Olive oil spray, or 1–2 tbsp olive oil for drizzling

Instructions

  1. Preheat the oven to 200°C (400°F) (all oven types).
  2. Bring a large pot of salted water to the boil and cook the pasta according to the packet instructions. Rinse in cold water to stop the pasta cooking, then drain and set aside.
  3. Heat the butter in a large, deep, heavy-based ovenproof frying pan over medium heat. Once melted, add the garlic and cook, stirring, for 30 seconds.
  4. Add the flour and stir it through until it is dissolved.
  5. Add half of the milk and whisk until well combined with the flour mixture. Add the remaining milk, bring to a simmer and cook, whisking constantly, for 4–5 minutes until thickened.
  6. Remove from the heat and stir through the baby spinach and peas.
  7. Add the tuna, lemon zest and juice, cheddar, parmesan, salt and pepper. Stir to combine.
  8. Toss the cooked pasta shells through the sauce, using your spoon to fill some of the shells with the mixture. Turn some of the shells so they are facing upwards (for presentation). If you don’t have an ovenproof frying pan, transfer to a baking dish.
  9. For the panko topping, sprinkle over the cheddar, parmesan and panko breadcrumbs, in that order. Spray with olive oil spray or drizzle with olive oil.
  10. Bake for 15–20 minutes until golden brown and bubbling around the edges.
  11. Serve immediately.

Notes

Note 1 – For a milder flavour, you can use tuna in springwater, instead of olive oil.

 

Make ahead

Freeze ahead – Assemble the dish, cover with foil and freeze for up to 3 months. Thaw in the fridge overnight before baking.
