Ingredients
Scale
Main Ingredients
- 340g baby spinach, roughly chopped
- 400g can chopped tomatoes with garlic and herbs
- 225g sustainable white fish fillets, chopped into large chunks
- small bunch basil, shredded
- 100g cooked and peeled prawns
Topping
- 2 tbsp finely grated parmesan
- 2 tbsp breadcrumbs
- 2 tbsp oats
To Serve
- 170g broccoli, boiled or steamed
Instructions
- Prepare the Spinach: Place the chopped spinach in a large colander and pour boiling water over it to wilt. Once it’s cool enough to handle, squeeze out the excess water to prevent a watery gratin. Season the spinach with salt and pepper to taste.
- Make the Tomato Sauce: Pour the canned chopped tomatoes with garlic and herbs into a frying pan. Season with salt and pepper, then simmer gently for about 5 minutes, allowing the sauce to thicken slightly.
- Add Fish and Basil: Add the chunks of sustainable white fish to the tomato sauce and heat for 1-2 minutes until they start to firm up but are not fully cooked. Stir in the shredded basil to infuse the sauce with fresh aroma.
- Preheat the Oven: Heat the oven to 220°C (200°C fan)/Gas Mark 7 to prepare for baking the gratins.
- Assemble the Gratin: Divide the squeezed spinach evenly between two gratin dishes. Spoon the fish, prawn, and tomato sauce mixture over the spinach layers.
- Create the Topping: In a small bowl, mix together the parmesan, breadcrumbs, and oats. Sprinkle this mixture evenly over the fish and tomato layer in each gratin dish to create a crispy topping.
- Bake: Place the gratin dishes in the preheated oven and bake for 20 minutes or until the topping is golden brown and bubbling hot.
- Serve: Remove from the oven and serve immediately alongside the boiled or steamed broccoli for a delicious and balanced meal.
Notes
- Ensure to squeeze out all excess water from the spinach to avoid a soggy gratin.
- Use sustainable fish varieties for an environmentally friendly dish.
- If you prefer, you can substitute the prawns with other seafood such as scallops or crab meat.
- For extra flavor, add a pinch of chili flakes into the tomato sauce while simmering.
- Using oats in the topping adds a nutritious twist and contributes to a crunchy texture.
- Broccoli can be steamed or boiled lightly to retain its vibrant color and crunch.
