Finding high-quality frozen prawns that deliver on flavour and texture can feel like a challenge. Too often, what looks promising in the freezer aisle ends up being disappointing once cooked. As home cooks and food enthusiasts, we want convenience without compromising on the quality needed for a truly delicious meal.
This guide is designed to help you navigate the options when you want to buy prawns online. We will break down the different types available, explain what to look for and offer some practical recommendations to help you choose the right frozen prawns for your next culinary project, from a quick weeknight stir-fry to a show-stopping paella.
Your Guide to Choosing Frozen Prawns
Before adding to your basket, understanding a few key terms can make all the difference. This will ensure you get exactly what your recipe requires.
1. Raw vs. Cooked: What's the Difference?
The first choice you will often face is between frozen raw prawns and frozen cooked prawns.
- Raw Prawns: These are translucent and greyish in colour. They are the most versatile option as they need to be cooked from scratch. This allows them to absorb the flavours of your dish, whether it's a fragrant curry, a garlic and chilli marinade or a simple butter sauce. They are ideal for dishes where the prawn is a central, flavour-infused ingredient.
- Cooked Prawns: These are pink and opaque, having been cooked before being frozen. Their main advantage is convenience. They are ready to eat once thawed, making them perfect for prawn cocktails, salads, sandwiches or being gently warmed through at the very end of cooking a pasta dish. Be careful not to overcook them, as this can make them tough.
2. Understanding the Format: HOSO vs. P&D
Prawns come in several preparations, each suited to different purposes.
- Head-On, Shell-On (HOSO): As the name suggests, these are whole prawns. Many chefs prefer head on shell on prawns because the head and shell lock in moisture and a significant amount of flavour during cooking. The shells and heads can also be used to make a rich, flavourful seafood stock, adding another layer of depth to your cooking.
- Peeled and Deveined (P&D): For ultimate convenience, peeled and deveined prawns are the go-to choice. The shell has been removed and the digestive tract (the "vein") has been taken out, making them ready to cook straight from the bag. This saves considerable preparation time, especially when cooking for a crowd.
3. The Importance of IQF
You will often see the term IQF prawns on packaging. This stands for Individually Quick Frozen. It means each prawn was frozen separately, rather than in a large, solid block of ice. This method is superior as it helps preserve the individual texture of each prawn, prevents them from clumping together and allows you to easily take out only the portion you need, keeping the rest perfectly frozen for another time.

For Effortless Entertaining: ADRIENNE Crevettes Tropical HOSO Cooked Shrimps
- Why It Stands Out: These prawns are fully cooked and frozen, offering exceptional convenience. The Head-On, Shell-On (HOSO) format makes for a visually impressive presentation, perfect for seafood platters or as a centrepiece. They are ready to serve once thawed.

- Ready to eat after thawing, no cooking required.
- The HOSO format retains natural sweetness and looks striking.
- IQF for easy portioning.

For Maximum Flavour: ECUAGOLD Frozen Head On Shell On Raw Prawns
- Why It Stands Out: These are large frozen prawns in their raw, HOSO state, which is the format many chefs choose for achieving the deepest flavour. Cooking them with the head and shell on keeps the flesh incredibly juicy and succulent. The shells can then be used to create a delicious stock.
- Pros:
- Raw format allows for maximum flavour absorption from marinades and sauces.
- Shells and heads are perfect for making rich seafood broths.
- The extra-large 20/30 size provides a satisfying, meaty bite.

For Ultimate Convenience: ROYAL STAR Raw Peeled & Deveined Prawns
- Why It Stands Out: These frozen king prawns are the definition of "chef-ready." They come fully peeled and deveined, saving you valuable time and effort in the kitchen. As they are raw, they still offer the versatility to be used in any cooked dish while eliminating the messy prep work.
- Pros:
- Completely ready to cook, with no peeling or deveining needed.
- IQF technology ensures freshness and easy portion control.
- Versatile raw state is ideal for stir-fries, curries, pasta and skewers.

Frequently Asked Questions
What do the numbers on prawn packaging mean (e.g., 21/25)?
These numbers refer to the size grading of the prawns, indicating the approximate number of prawns per kilogram or pound. A smaller number range means larger prawns. For example, a bag graded 21/25 will contain between 21 and 25 large frozen prawns per unit of weight, whereas a bag graded 30/40 will contain smaller prawns.
Do I need to defrost frozen prawns before cooking?
For the best results, yes. Cooking prawns from frozen can lead to uneven cooking, with the outside becoming tough before the inside is cooked through. The best way to thaw them is to place them in the refrigerator overnight. For a quicker method, put the frozen prawns in a colander and run them under cold water until they are fully thawed. Pat them dry with a paper towel before cooking.
How can I tell if frozen prawns are good quality?
Good quality frozen prawns should feel firm to the touch once thawed. They should have a fresh, clean scent of the sea, not an overly "fishy" or ammonia-like odour. Visually, look for prawns with minimal ice crystals on the surface. A heavy coating of ice can indicate that the product may have partially thawed and been refrozen, which can negatively affect the texture.
