Cooking Seafood for a Crowd: Easter Entertaining Made Easy

Cooking for 4 is straightforward. Cooking for 10, 15, or 20? That's where the panic sets in. The timing goes wrong, the kitchen's a disaster zone, and you're plating the last course while your first guests are finishing. We see this every Easter — customers come to us stressed about feeding a big group. Here's how to make it painless.

The Golden Rule: Don't Try to Cook Everything to Order

This is the mistake that derails every large Easter gathering. Pan-searing individual fish fillets for 15 people one at a time is a recipe for a nervous breakdown. Instead, choose dishes that can be:

1. Prepared in advance (cold platters, boiled prawns)
2. Cooked in bulk (sheet-pan baked fish, whole roasted fish)
3. Served at room temperature (salads, smoked salmon)
4. Held warm (seafood chowder in a slow cooker)

How Much Seafood to Buy

Per Person Guidelines

| Meal Type | Fish | Prawns | Other | Total | |-----------|------|--------|-------|-------| | Sit-down main | 200g | 100g | 80g | 380g | | Buffet (seafood only) | 150g | 80g | 60g | 290g | | Buffet (mixed dishes) | 100g | 60g | 40g | 200g | | Platter/grazing | — | 80g | — | 80g |

For 12 people at a sit-down Good Friday lunch:

• 2.4kg fish fillets
• 1.2kg prawns (shell-on weight)
• 1kg mixed (oysters, calamari, etc.)
• Total: approximately 4.5–5kg

Our rule of thumb: Calculate what you think you need, then add 15%. You never want to run out, and leftover seafood makes excellent sandwiches, salads, and fried rice the next day.

Scaling Common Recipes

Garlic Prawns

• For 4: 500g prawns, 2 garlic cloves, 40g butter
• For 12: 1.5kg prawns, 6 garlic cloves, 120g butter
• Note: Cook in 2 batches. Overcrowding the pan drops the temperature and steams instead of searing.

Beer-Battered Fish

• For 4: 4 fillets, 1 cup flour, 1 cup beer
• For 12: 12 fillets, 3 cups flour, 3 cups beer
• Note: Fry in batches of 3–4. Keep finished pieces warm on a wire rack in a 120°C oven.

Baked Salmon

• For 4: 4 fillets on 1 tray, 15 minutes
• For 12: 12 fillets on 3 trays, stagger by 3 minutes so they finish at different times
• Note: This is the easiest dish to scale. Just add more trays.

Equipment Checklist

Before you start, make sure you have:

• [ ] Enough sheet trays / baking dishes
• [ ] Large serving platters
• [ ] Crushed ice (2–3 bags from the servo)
• [ ] Serving tongs, fish slices, and spoons
• [ ] Paper towels (you'll use a lot)
• [ ] A large pot for boiling prawns
• [ ] A thermometer if deep frying
