How to Make Southern Fried Prawns

Step 1: Marinate the Prawns

This helps tenderise the prawns and creates a coating that adheres beautifully.

Mayonnaise
Sour cream
Dill
Chives
Garlic
Lemon juice
Buttermilk

Mix until smooth and refrigerate until serving.

Using the correct temperature ensures:

Crispy coating
Even cooking
Less oil absorption

Step 4: Coat the Prawns

Combine:

Self-raising flour
Cajun seasoning
Salt

Coat each prawn thoroughly.

The prawn flesh should not be visible through the flour mixture.

Step 5: Fry Until Golden

Cook in batches for 1–2 minutes until:

Golden brown
Crispy
Just cooked through

Transfer to a wire rack to maintain crispness.

Step 6: Serve

Drain on a Wire Rack

A wire rack keeps the coating crisp better than paper towels alone.

Frequently Asked Questions

Can I use frozen prawns?

Yes. Thaw completely and pat dry before marinating.

Why marinate in buttermilk?

Buttermilk helps tenderise the prawns and improves coating adhesion.

Can I make the ranch sauce ahead?

Yes. Prepare up to 24 hours in advance and refrigerate.
