Frozen prawns are a convenient and delicious option for seafood lovers who want to enjoy the taste of the ocean without spending too much time or money. However, not all frozen prawns are created equal, and selecting the best ones can be daunting. In this article, we will guide you through choosing the best frozen prawns so that you can enjoy mouthwatering dishes with ease.

Know Your Prawns: Types and Sizes

Before diving into the world of frozen prawns, it is vital to understand the different types and sizes available in the market. There are various species of prawns, but the most common ones include:

  • Tiger Prawns – Known for their distinctive black and white stripes, tiger prawns are large and have a firm texture. They are ideal for grilling and barbecuing.
  • King Prawns – These large prawns have a sweet and succulent flavour. They work well in curries, stir-fries, and pasta dishes.
  • Whiteleg Prawns – Also known as Pacific white shrimp, these prawns are smaller and have a mild flavour. They are perfect for salads, tacos, and light dishes.

Regarding size, prawns are often labelled by the number of pieces per pound (e.g., 16/20, 21/25). The lower the number, the larger the prawn.

What to Look for When Buying Frozen Prawns

Packaging and Appearance

The packaging of frozen prawns can provide valuable information about their quality. Make sure to look for the following when examining the package:

Clear and intact packaging

The packaging should be transparent so you can see the prawns inside, and there should be no tears or punctures.

No freezer burn

Freezer burn appears as white, icy patches on the prawns. It is a sign of dehydration and can affect the taste and texture of the prawns.

Minimal ice crystals

A small number of ice crystals are normal, but an excessive amount may indicate that the prawns have been thawed and refrozen.

Sustainably Sourced

Choose frozen prawns that are sustainably sourced to ensure you are supporting environmentally responsible practices. On the packaging, look for certifications like Marine Stewardship Council (MSC) or Aquaculture Stewardship Council (ASC).

Origin and Processing

The country of origin and processing can also impact the quality of frozen prawns. Prawns from countries with strict regulations and high-quality standards, such as Australia and New Zealand, are often considered superior. Furthermore, prawns that have been processed and frozen quickly after harvest will retain their freshness and flavour better than those transported long distances before freezing.

How to Store and Prepare Frozen Prawns

To maintain the quality of your frozen prawns, store them in the coldest part of your freezer, ideally at -18°C or below. When you are ready to cook them, thaw the prawns in the refrigerator overnight or under cold running water. Avoid using hot water or microwaving them, which can cause uneven thawing and affect their texture.

Once thawed, it is essential to cook the best frozen prawns thoroughly to ensure food safety. Cook them until they turn opaque and pink, with an internal temperature of 74°C (165°F).


Selecting the best frozen prawns can be a breeze if you know what to look for. Remember the type and size of prawns you prefer, examine the packaging and appearance, and opt for sustainably sourced and high-quality options.
