easy oven-baked garlic prawns recipe


I have used more frozen food products during the past year than I have during the last decade. Their convenience has grown on me, especially vegetables which require very little preparation. Most surprising is frozen raw seafood. This New Years‘s Eve, I discovered that you can bake frozen prawns! It is not fresh off the boat but satisfying none the less. The key is preparation – defrosting and not to overcook.  I made garlic prawns and squid in the oven. It was my first experience with frozen prawns, a rather satisfying one. They are certainly better suited for making prawn biryani than pre-cooked ones are. For this recipe, I opted for a lemon, rosemary and olive oil marinade. My favoured flavour combination after making lemon and rosemary leg of lamb. I used olive oil instead of butter, under the guise of a healthy start to the year. Served with oven Belgian fries (believe it or not also considered a healthy potato chip) More about that in another post. The perfect compliment to this meal was tapenade and dry white wine.

Can You Cook Frozen Cooked Prawns Without Defrosting?

This is
a common question when preparing frozen prawns. Unfortunately, the
answer … better not!. The result will be rubbery overcooked prawns.
For best results, I recommend defrosting overnight in the fridge. If the
prawns have been frozen for a long time it may require a longer
defrosting time. If there are traces of icicles, simply rinse the prawns
with cold water then pat dry with a paper towel before marinating. Less
excess moisture will allow the prawns to cook in their moisture,
resulting in succulent prawns.


How to Make Garlic Prawns with Frozen Raw Prawns

To make this recipe I recommend lots of garlic, chopped in fine pieces or grated, combine with lemon juice and olive oil. Add fresh green chilli or red chilli flakes for added zing.

After defrosting, pat the prawns dry with a paper towel. Rub in grated garlic, sprinkle with salt and rosemary then drizzle with olive oil. Work the added ingredients into the prawns by gently turning over. Allow resting for 15 minutes or so before baking.
