Cod & Anchovy Bake Recipe
Introduction
This Cod & Anchovy Bake is a comforting and flavorful dish that combines tender cod loins with a savory tomato and anchovy sauce layered over soft potatoes and onions. Perfect for a hearty family meal, it’s topped with golden cheddar for a delicious finish.

Ingredients
- 1 large or 2 medium potatoes, sliced into 5mm-thick rounds (about 280g)
- 1 onion, thinly sliced (about 160g)
- 1 tbsp thyme leaves
- 10g anchovies, finely chopped
- 1 tbsp olive or rapeseed oil
- 1 red pepper, quartered, deseeded and sliced
- 2 large tomatoes, roughly chopped (about 250g)
- 1 tsp white wine vinegar
- ½ tsp vegetable bouillon powder
- 1 garlic clove, finely grated
- 2 skinless, boneless cod loins (280g)
- 25g cheddar, finely grated
- 250g baby spinach, wilted, to serve
Instructions
- Step 1: Cook the sliced potatoes and onions in boiling water for 5-7 minutes until just tender. Drain well and gently mix them with thyme leaves, finely chopped anchovies, and a good crack of black pepper.
- Step 2: While potatoes cook, heat the oil in a pan over medium heat. Add the sliced red pepper, cover, and cook for 5 minutes until softened.
- Step 3: Add the chopped tomatoes, white wine vinegar, vegetable bouillon powder, and grated garlic to the pan. Cook uncovered for 8-10 minutes, stirring occasionally, until the tomatoes have softened and excess liquid has evaporated.
- Step 4: Preheat your oven to 200°C (180°C fan)/gas mark 6. Place the cod loins in a shallow ovenproof dish.
- Step 5: Spoon the tomato and pepper mixture evenly over the cod loins. Next, layer the potato and onion mixture on top, spreading it out evenly.
- Step 6: Sprinkle the grated cheddar over the layered ingredients. Bake in the oven for 30 minutes until the cheese is golden and bubbling, and the fish flakes easily but remains moist.
- Step 7: Serve the bake hot alongside wilted baby spinach for a fresh, nutritious finish.
Tips & Variations
- Use fresh thyme leaves for the best aroma, but dried thyme works well in a pinch—use about one-third of the amount.
- If you prefer a milder anchovy flavor, reduce the quantity to 5g or rinse the anchovies lightly before chopping.
- Swap cheddar for Parmesan or Gruyère for a different cheese twist.
- For a richer dish, add a splash of cream to the tomato mixture before layering.
Storage
Store any leftovers in an airtight container in the refrigerator for up to 2 days. Reheat gently in a low oven or microwave until warmed through. The fish is best eaten fresh, but careful reheating helps keep it moist.

FAQs
Can I use frozen cod instead of fresh?
Yes, frozen cod can be used. Thaw it completely and pat dry before assembling the bake to avoid excess moisture.
Is there a substitute for anchovies if I don’t like them?
You can omit anchovies or substitute with a teaspoon of capers or olives to add a similar salty, savory depth without the fishy taste.

Ingredients
Potato & Onion Mixture
- 1 large or 2 medium potatoes, sliced into 5mm-thick rounds (about 280g)
- 1 onion, thinly sliced (about 160g)
- 1 tbsp thyme leaves
- 10g anchovies, finely chopped
- Black pepper, to taste
Tomato & Pepper Sauce
- 1 tbsp olive or rapeseed oil
- 1 red pepper, quartered, deseeded and sliced
- 2 large tomatoes, roughly chopped (about 250g)
- 1 tsp white wine vinegar
- ½ tsp vegetable bouillon powder
- 1 garlic clove, finely grated
Other Ingredients
- 2 skinless, boneless cod loins (280g)
- 25g cheddar, finely grated
- 250g baby spinach, wilted, to serve
Instructions
- Prepare the Potatoes and Onions: Boil the sliced potatoes and thinly sliced onions in boiling water for 5-7 minutes until just tender. Drain well and transfer to a bowl.
- Mix with Seasonings: Gently fold the thyme leaves, finely chopped anchovies, and a pinch of black pepper into the drained potatoes and onions. Set aside.
- Cook the Peppers: Heat the olive or rapeseed oil in a frying pan over medium heat. Add the quartered, deseeded, and sliced red pepper, cover the pan, and cook for 5 minutes until slightly softened.
- Add Tomatoes and Flavors: Stir in the chopped tomatoes, white wine vinegar, vegetable bouillon powder, and finely grated garlic. Continue cooking uncovered for 8-10 minutes, until the tomatoes have softened and much of the liquid has evaporated, resulting in a thick sauce.
- Preheat the Oven: Set the oven to 200°C (180°C fan) or gas mark 6.
- Assemble the Bake: Place the cod loins evenly in a shallow ovenproof dish. Spoon the tomato and pepper mixture evenly over the cod, then layer the potato and onion mixture on top. Sprinkle the grated cheddar evenly over the surface.
- Bake the Dish: Bake in the preheated oven for 30 minutes, until the cheese is golden and bubbly, and the cod flakes easily but remains moist.
- Prepare Spinach and Serve: While baking, wilt the baby spinach by lightly steaming or sautéing. Serve the baked cod and vegetable layers hot with the wilted spinach on the side.
Notes
- You can substitute cheddar with another melting cheese like mozzarella or gruyere for a different flavor.
- Ensure the tomato mixture is not too wet before assembling to prevent soggy layers.
- Adjust seasoning with salt if needed, but remember anchovies and bouillon add saltiness.
- Baby spinach can be wilted by briefly sautéing in a little olive oil or by steaming.
- This dish is ideal for a balanced, hearty dinner and can be prepared ahead and baked just before serving.
