Gnocchi Fish Pie Recipe
Introduction
This comforting gnocchi fish pie combines soft gnocchi with a creamy, flavorful fish filling. It’s a quick and satisfying twist on a classic pie, perfect for a family dinner that feels special but is easy to prepare.

Ingredients
- 350g gnocchi
- 200ml semi-skimmed milk
- 2 tbsp cornflour
- 400g fish pie mix, or a mix of salmon, smoked haddock and prawns
- 4 spring onions, sliced
- 1 tbsp chopped chives, or ½ tbsp finely chopped tarragon
- 150ml reduced-fat crème fraîche
- 1 tsp capers, drained
- 200g frozen peas
- 1 tsp olive oil
- 250g long-stem broccoli or green beans, steamed, to serve
Instructions
- Step 1: Place the gnocchi in a deep ovenproof frying pan and cover with boiling water and a pinch of salt. Simmer for 2–3 minutes, then drain and leave to steam-dry.
- Step 2: Mix a small amount of the milk with the cornflour until smooth, then add this to the remaining milk. Pour the mixture into the frying pan with the gnocchi.
- Step 3: Add the fish pie mix and sliced spring onions to the pan. Bring to a gentle simmer, stirring frequently, and cook for 4–5 minutes or until the sauce thickens and the fish is just cooked. Season well.
- Step 4: Stir in the chopped herbs, crème fraîche, capers, and frozen peas, and bring back to a simmer.
- Step 5: Preheat the grill to medium-high. Arrange the gnocchi evenly over the fish filling, brush with olive oil, and season with black pepper.
- Step 6: Grill for 5–10 minutes until the gnocchi puffs up and turns golden on top. Serve immediately with steamed broccoli or green beans on the side.
Tips & Variations
- Use fresh herbs like dill or parsley for a different flavor twist.
- Swap crème fraîche for Greek yogurt for a tangier, lighter option.
- Add a sprinkle of grated cheese on top before grilling for a crusty finish.
- If you don’t have a grill, finish the dish under a hot oven grill setting or bake at 200°C for 10–12 minutes.
Storage
Store any leftovers in an airtight container in the refrigerator for up to 2 days. Reheat gently in the oven or microwave until warmed through. The gnocchi topping may soften upon reheating but will remain tasty.

To Serve

Instructions
- Cook Gnocchi: Place the gnocchi in a deep ovenproof frying pan and cover with boiling water and a pinch of salt. Simmer for 2-3 minutes until just cooked, then drain and leave to steam-dry in the pan.
- Prepare Sauce: In a small bowl, mix a splash of the semi-skimmed milk with cornflour to form a smooth paste. Add this to the remaining milk and pour the mixture into the frying pan with the cooked gnocchi. Add the fish pie mix and sliced spring onions.
- Simmer Sauce & Cook Fish: Bring the pan contents to a gentle simmer, stirring frequently, and cook for 4-5 minutes until the sauce thickens and the fish is just cooked. Season well with salt and pepper.

- Serve: Serve the gnocchi fish pie hot from the pan, accompanied by steamed long-stem broccoli or green beans on the side for a fresh green balance.
Notes
- Using an ovenproof frying pan is essential as the dish moves directly from stovetop to grill.
- Ensure the sauce is gently simmered to prevent overcooking the fish, which can become tough.
- For a dairy-free version, substitute crème fraîche with a plant-based alternative and use suitable milk.
- Gnocchi can be fresh or store-bought; cooking times may vary slightly depending on type.
- Steaming the vegetables preserves their nutrients and complements the creamy fish filling perfectly.
