Recipe Steps

24 min

  • Step 1

    Preheat the oven to 400 degrees Fahrenheit.
  • Step 2

    Crack the eggs into a mixing bowl, season with salt and pepper and beat together to combine.
    Step 2
  • Step 3

    Add the watercress, discarding any tough stems and stir into the beaten egg. Set aside.
    Step 3
  • Step 4

    Thinly slice the onion. Heat the oil in an oven proof skillet over a low/medium heat. Add the onion and capers and sweat gently for 2-3 minutes until tender and fragrant.
    Step 4
  • Step 5

    Flake in the tuna and stir well to combine, distributing the filling evenly across the base of the skillet.
    Step 5
  • Step 6

    Pour the beaten egg and watercress over the tuna and allow to settle and cook for a few minutes. Once the frittata starts to set around the edges, use a spatula to gently ease the cooked egg away from the skillet sides, allowing any uncooked egg to flow underneath.
    Step 6
  • Step 7

    Once the frittata is almost cooked through with a thin layer of liquid remaining on the surface, transfer to the oven to bake for a further 6-7 minutes or until cooked through and golden brown all over. Carefully slide out of the skillet using a spatula to serve.
    Step 7

    Tasty and I say it filled me up I used spinach and onion only. But it was very filling!

        Good, but it needed garlic,so I added a chopped clove to the onions otherwise it was bland.
