The basics
Fish is the most perishable thing in the kitchen, so the skill of using it well is partly cooking and partly planning. Buy fresh fish for the first meals in the week, and keep frozen fish and tinned fish for the days after. Cook the fresh fish on the day you buy it or the next. Frozen fish is excellent if it is frozen well and thawed slowly in the fridge.
A fish supper needs timing, because fish cooks in minutes and goes cold quickly. Everything else should be ready before the fish goes on: potatoes boiling, vegetables prepped, plates warming. This chapter brings together the whole course: Cooking Skills: Fish and Shellfish 1, chapters 1 to 7. For wider meal planning see Cooking Skills: Potatoes 1, chapter 9, and for a sauce to go with fish Cooking Skills: Sauces 1, chapter 6.
The method
- Plan the week: fresh fish for the first two days, then frozen, tinned and smoked fish.
- Write the timeline backwards from serving time, with the fish going on last.
- Prepare sauces and sides first; fish is the last thing to cook and the first to be spoilt by waiting.
- Freeze extra fillets on the day you buy them, wrapped well and labelled.
- Defrost in the fridge overnight, and cook within a day.
| Day | Fish | Style | From |
|---|---|---|---|
| Monday | Fresh sea bass or salmon | Pan-fried or baked | Chapters 2 and 3 |
| Tuesday | Prawns or mussels | Quick shellfish dish | Chapter 6 |
| Wednesday | Frozen white fish | Fish fingers or tacos | Chapters 1 and 7 |
| Thursday | Smoked haddock | Kedgeree or pie | Chapters 4 and 5 |
| Friday | Tinned sardines or mackerel | Toast or pâté | Chapter 1 |
Freezing, defrosting and keeping fish safe
Raw fish: keep raw fish on its own board and plate, away from food that won't be cooked. Wash your hands, boards and knives in hot soapy water afterwards, and store raw fish on a plate on the bottom shelf of the fridge so it can't drip onto other food.Leftover fish: cool cooked fish quickly, refrigerate it within 1 to 2 hours, and eat it within about 1 day (2 at most). Reheat only once, until steaming hot all the way through. Do not refreeze fish that was frozen and thawed unless you cook it first.
Freezing and defrosting: freeze fish flat in labelled bags for up to about 3 months (general guidance). Defrost on a plate on the bottom shelf of the fridge, never on the worktop, and cook it within a day. Do not refreeze raw fish that has thawed.

Level 1 · Start here
A fish supper for four
Pan-fried sea bass with lemon butter, buttered new potatoes and green beans. The fish takes 6 minutes, so everything else is ready first. Follow the timeline and keep plates warm. Pan-frying is covered in Cooking Skills: Fish and Shellfish 1, chapter 2.
Ingredients (4 portions)
- 4 sea bass fillets, skin on
- 600 g baby new potatoes
- 200 g green beans, trimmed
- 50 g butter
- 1 lemon, juiced
- 2 tbsp chopped parsley
- 1 tbsp rapeseed or sunflower oil
- 45 minutes before: boil the potatoes for 15 to 20 minutes. Warm the plates in a low oven. Dry the fish well on kitchen paper.
- 10 minutes before: boil the beans for 4 minutes and drain. Heat the oil, lay the fish skin side down and cook 3 to 4 minutes without moving it.
- Turn the fish for 1 minute, add half the butter and the lemon juice to the pan, and toss the potatoes with the rest of the butter and parsley. Serve at once.
Hot pan, boiling water and allergens
Hot pan and hot oil: frying fish uses a hot pan and spitting oil. Dry the fish well, lay it down away from you, use a splash guard if you have one, keep the handle turned in and keep children well back.Hot liquid and steam: hot milk, stock and poaching liquid scald badly and steam burns faster than boiling water. Keep the handle turned in, lift lids away from your face, use a slotted spoon or fish slice over the pan, and never carry a full pan across a busy kitchen.
Is it cooked?: fish is done when the flesh turns opaque (no longer glassy) and flakes easily with a fork. A probe thermometer reads about 63°C in the thickest part (general guidance). Take it off the heat a minute early, because it keeps cooking as it rests.
Allergens: fish is one of the 14 major allergens, and cross-contact is easy: it can pass on boards, oil, tongs and pans. Crustaceans (prawns), molluscs (mussels, scallops), gluten, milk and egg also appear in fish recipes. Always tell guests what is in a dish.
Level 2 · Plan
A week of fish meals
Plan five fish meals for two, using fresh, frozen, smoked and tinned fish across the week. Buy on Sunday or Monday and freeze whatever is not for the first two days. The shopping list shows the fish, with the vegetables left to you.
Ingredients (5 meals for 2)
- 300 g fresh sea bass or salmon (Monday)
- 300 g raw prawns or mussels (Tuesday, buy that day)
- 300 g frozen white fish (Wednesday)
- 300 g undyed smoked haddock (Thursday)
- 2 tins of sardines or mackerel (Friday)
- 1 freezer bags and a marker
- On Sunday write the plan: day, fish, method, and the chapter in this course. Check what is in the freezer.
- Buy the Monday fish fresh; put the Wednesday fish in the freezer if it is fresh, or take it out on Tuesday night to defrost in the fridge.
- Each evening cook the planned dish, and tick it off. At the end of the week note what you would change.

Level 2 · Freezer
Freezing a batch of fish
Buy a larger pack when fish is on offer and freeze it in portions. Freeze it the day you buy it. Good wrapping stops freezer burn. Label each bag with the fish, the date and the number of portions.
Ingredients (4 fillets)
- 4 fresh fish fillets
- 4 freezer bags
- 1 roll of cling film
- 1 permanent marker
- 1 plate for defrosting
- Pat the fillets dry, wrap each tightly in cling film and put each in a freezer bag, pressing out the air. Label with the fish, date and portions.
- Freeze flat on a tray for 2 hours, then stack. Use within about 3 months.
- To defrost, put a fillet on a plate on the bottom shelf of the fridge overnight. Pat dry before cooking and cook within a day.

Level 3 · Signature
Your signature fish dish
Choose a fish, a method (pan-fry, bake, poach, grill or coat) and a sauce (lemon butter, dill yogurt, salsa or parsley sauce), and write the recipe as you cook it. Make it twice, changing one thing. A signature dish is one you can cook without a recipe.
Ingredients (your choice)
- 1 fish of your choice (about 150 g a person)
- 1 method from chapters 2 to 7
- 1 sauce or topping of your choice
- 1 notebook and pen
- Choose your fish, method and sauce, and write them down before you start.
- Cook it, noting the times, the temperatures and what you would change.
- Cook it again with your change, then write the final recipe on a card.

Experiments
Experiment
A timed fish session
Planning.
- Cook a full fish supper for two with a timer and write down when each task started and finished.
Look for: You will see that fish is the quickest part and the vegetables set the pace. Start the slow things first.
Experiment
Swap one fish
Flexibility.
- Cook the same recipe with a different fish, for example salmon instead of sea bass.
Look for: Oily and white fish cook differently; note how much the timing and the flavour change.
Experiment
Freezing against fresh
Quality.
- Cook a fresh fillet and one frozen for a month, the same way, and compare.
Look for: Properly wrapped fish loses very little; badly wrapped fish is dry at the edges. Wrapping matters.
Experiment
Your own signature dish
Making it yours.
- Cook your signature dish for a friend and ask for one comment.
Look for: A repeated dish improves every time. Write it down.

Troubleshooting
| Problem | Likely cause | What to do |
|---|---|---|
| Fish ready but sides not | Poor timing | Write the timeline backwards and start the slow items first |
| Fish cold at the table | Plates cold or waited too long | Warm the plates and serve at once |
| Frozen fish watery | Thawed too fast or wrapped badly | Defrost in the fridge, pat dry, and wrap tightly |
| Fish smells before cooking | Old fish | Don't eat it; buy fresh next time |
| Week plan falls apart | Too ambitious | Plan fewer fresh-fish days and rely on frozen and tinned |
| Freezer burn | Air in the bag | Press out the air and double-wrap |
Freezing, leftovers and allergens
Leftover fish: cool cooked fish quickly, refrigerate it within 1 to 2 hours, and eat it within about 1 day (2 at most). Reheat only once, until steaming hot all the way through.
