Healthy Tuna Mornay Bake

This ultimate healthy tuna bake is creamy-comfort vibes without the heavy calories: a rich tomato-basil “mornay-style” sauce folded through chickpea pasta and tuna, finished with a golden parmesan top. It’s a high-protein, family-friendly dinner that lands around ~500 cals per serve, and it pairs perfectly with a chilled BE on the side for the easiest, feel-good meal prep win.

Serves 4

Ingredients:

  • 1 tin of tuna (185 g), drained
  • 500 g passata
  • 1 chicken stock cube
  • 250 g chickpea pasta
  • 1 red onion, finely diced
  • 1 red capsicum, finely diced
  • 2 tbsp sun-dried tomatoes
  • Handful of fresh basil
  • 2 tsp crushed garlic
  • Parmesan cheese, for grating
  • Salt, pepper, and a drizzle of olive oil

Method:

  1. Preheat the oven to 180°C fan-forced.
  2. Dice the vegetables finely. Sweat the onion and capsicum in a deep pan or cast iron skillet with a pinch of salt and pepper for ~10 minutes, until golden and fragrant, and any excess water has evaporated.
  3. Meanwhile, cook the pasta in salted boiling water, removing it 2 minutes before the packet instructions for al dente texture.
  4. Mash together the sun-dried tomatoes, basil, and crushed garlic to form a paste. Add this to the vegetable mix and fry for a few minutes. Pour in the passata, 150 ml water, and crumble in the chicken stock cube. Simmer for 10 minutes, stirring occasionally, until thickened.
  5. Stir in the drained tuna and the pasta. Transfer the mixture to a deep baking dish if your skillet isn’t oven-safe. Grate a generous amount of Parmesan over the top, season with black pepper, and drizzle with olive oil.
  6. Bake for 6–10 minutes, then switch to grill mode for the last few minutes to crisp up the top. Serve warm.
