If prawns are a favourite in your house, this Kerala prawn roast is one of the best ways to cook them. It’s quick, packed with flavour, and tastes like something from a coastal restaurant.
This Kerala prawn roast, also called chemmeen roast, is irresistibly tasty yet simple to prepare. A fresh spice mix locks in bold flavours and, because the prawns go into the masala immediately, it’s essentially a convenient one-pan dish. It works brilliantly as an appetizer or as the star of a coastal-style meal.
I like serving this at gatherings because it disappears fast, but it also makes a great weekend lunch with neer dosa, appams, or with dal and roti. The concentrated, roasted masala clings to the prawns and gives a smoky, caramelised finish that guests always praise.

Ingredients for Kerala Prawn Roast
Prawns: 400 grams, peeled and deveined. Fresh prawns give the best texture and flavour; frozen prawns are fine if fully thawed and drained.
Marinade: crushed garlic, crushed ginger, coriander powder, cumin powder, crushed pepper, Kashmiri chilli powder, turmeric, fennel seed powder, and garam masala. These combine to make a fragrant, balanced masala that penetrates the prawns.
Sambar Onions: halved. They caramelise quickly on high heat and add natural sweetness to the roast.
Curry Leaves: used generously while frying and as a fresh finishing touch for aroma and taste.
Green Chillies: slit, for heat and layered flavour.
Coconut Oil: ideal for authentic Kerala flavour, though any neutral oil will work if preferred.
Top Tips
- Use a wide, flat pan. Give the prawns room to sit in a single layer so they roast and caramelise instead of steaming. If the pan is crowded, cook in batches.
- Leave prawns undisturbed initially. After adding them to the pan, allow 1–2 minutes without moving them so a good sear forms.
- Marinate at least 15 minutes. The spices need time to flavor the prawns properly; brief marination yields only surface flavour.
- Finish with a drizzle of coconut oil. Optional but traditional: added at the end for fragrance and richness.
- Defrost properly if using frozen prawns. Thaw in the fridge or under cold running water and pat dry to avoid excess moisture and potential spoilage.
Frequently Asked Questions
Prawn roast is a dry Kerala-style preparation where prawns are cooked in a spiced masala on high heat until the mixture caramelises and coats the prawns. Unlike a curry, there’s no gravy—the flavors concentrate and cling to each piece.
Prawns cook quickly: about 4–5 minutes once they hit the pan. High heat and minimal cooking time prevent them from turning chewy. As soon as they curl and turn pink, they are done.
Yes. Chicken can work with the same spice mix but requires a longer cook time. Firm fish fillets or thick vegetables like mushrooms or baby corn also take well to the masala.
Sliced, thick mushrooms or halved baby corn roast nicely in this masala. While they won’t taste like prawns, the coastal spices and coconut oil give them a satisfying, savory finish.
Storage Tips
- Fridge: Store in an airtight container for up to 2 days. Flavours remain good, though the crispness lessens.
- Freezing: Not recommended. Texture changes lead to rubbery reheated prawns.
- Reheating: Warm briefly on a hot pan for a minute or two to revive the roasted finish; avoid microwaving when possible.
Serving Ideas
This prawn roast works as a starter or as part of a larger meal. Popular pairings include:
- Jeera Rice: The cumin-scented rice pairs beautifully with the roasted spices.
- Neer Dosa: Soft, lacy neer dosa is a classic Kerala pairing that soaks up the masala perfectly.
- Tender Coconut Appam: Soft appams complement the spicy roast and add a hint of sweetness.
- On its own: Serve with a squeeze of lemon and sliced onions for a simple snack or appetizer.
Did You Know?
Prawns turn pink when cooked because of a pigment called astaxanthin. In raw prawns this pigment is bound to protein, making the shell appear grey or translucent. Heat releases astaxanthin, producing the bright pink-orange colour you see in cooked prawns. This same pigment helps flamingos get their pink colour from a diet rich in shrimp and algae.
This prawn roast is quick, bold and deeply flavorful — a great way to bring coastal Kerala flavours into your kitchen. Once you try it, it often becomes a repeat favourite because the technique is simple and the results are impressive.
Make it, enjoy it, and share your experience with friends and family.

Ingredients
For marination
- 400 g prawns, peeled & deveined
- 8 cloves garlic, crushed
- ¾ inch ginger, crushed
- 2 tsp coriander powder
- ½ tsp cumin powder
- ½ tsp crushed black pepper
- 1 tsp Kashmiri chilli powder
- ¼ tsp turmeric powder
- ¼ tsp fennel seed powder
- ¼ tsp garam masala
For roasting
- 3½ tbsp coconut oil or neutral oil
- ½ tsp fennel seeds
- ½ cup halved sambar onions
- 4 sprigs curry leaves, divided
- 2 green chillies, slit
- 1 tsp Kashmiri chilli powder (for paste)
- ½ tsp salt (adjust to taste)
Instructions
Marinating prawns
- Combine prawns with the crushed garlic and ginger and all the dry spices listed for marination. Mix thoroughly so each prawn is coated. Set aside to marinate for at least 15 minutes.
Prawn roast
- Heat 2 tablespoons of coconut oil in a wide, flat-bottomed pan over medium-high heat. Add fennel seeds and let them crackle briefly.
- Add the halved onions, two sprigs of curry leaves and the slit green chillies. Fry for about 1–1½ minutes until the onions turn light golden.
- Mix 1 teaspoon Kashmiri chilli powder with 2 tablespoons water to make a smooth paste.
- Add the marinated prawns and ½ teaspoon salt. Spread the prawns in a single layer so they roast rather than steam. Cook undisturbed for 1–2 minutes to get a good sear.
- Add the chilli paste, toss gently and continue cooking for 2–3 minutes until prawns are cooked through and coated in the roasted masala. Remove from heat.
- Optionally, drizzle 1½ tablespoons of coconut oil over the prawns for an authentic fragrance before serving. Garnish with the remaining curry leaves.
