Description
These grilled Cajun prawns come out juicy, buttery, and just messy enough to make you grab extra bread for the sauce. The garlic butter with thyme and chili sinks right into the prawns while the edges get slightly crisp from the grill.
Ingredients
- 30 to 40 prawns, cleaned, deveined, washed, and drained well
- 2 to 3 tbsp olive oil, for coating prawns
- Cajun spice, to taste
- 1.1 cup approx – 250 g butter
- 1/2 cup olive oil
- 2 tsp crushed garlic
- 1 tsp dried thyme
- Salt, to taste
- 2 dried chili peppers, broken into pieces
- Lemon wedges, for serving, optional
Instructions
- Preheat your oven to 425⁰F (220⁰C).
- If your prawns are still a bit wet, pat them dry with a paper towel first. This really helps them brown properly instead of steaming.
- Place the 30 to 40 cleaned prawns in a single layer in a large oven tray.
- Drizzle over 2 to 3 tbsp olive oil and sprinkle generously with Cajun spice.
- Toss everything together with your hands so all the prawns are lightly coated.
- Bake or grill the prawns on the middle oven shelf for about 8 to 10 minutes until the tops start browning.
- Turn them over and cook another 5 to 7 minutes until lightly crisp around the edges.
- The time will depend on your own oven, so be careful not to overcook them, or they’ll go rubbery pretty quickly
- While the prawns cook, add 250 g butter, 1/2 cup olive oil, 2 tsp crushed garlic, 1 tsp dried thyme, salt to taste, and 2 broken dried chili peppers to a saucepan.
- Cook the butter mixture over medium heat for about 10 minutes, stirring now and then.
- Keep the heat gentle so the garlic softens and flavours the butter without burning. If the garlic starts colouring too fast, lower the heat slightly.
- Remove the prawns from the oven and pour the hot garlic butter mixture evenly over them.
- Spoon some of the garlic and chili bits over the tops for that awesome flavour.
- Lower the oven temperature to 350⁰F (180⁰C) and return the tray to the oven for another 8 to 10 minutes so the prawns soak up the butter properly.
- Serve hot with lemon wedges and chopped parsley if using.
- Crusty bread, rice, or even hot chips work really well for soaking up the buttery sauce.
Notes
Created, prepared, tried, and tested by Irene
Additional Information
- Can This Be Frozen? Yes. Freeze cooked prawns in an airtight container with some of the butter sauce for up to 2 months.
- How Long Can This Be Stored? Store leftovers in the fridge for up to 2 days in a sealed container. Reheat gently so the prawns don’t toughen.
- Should the prawns be peeled? Either peeled or shell on works, but shell on gives more flavour.
- Can I make this less spicy? Yes, reduce the Cajun spice and use only 1 dried chili.
- Do I need fresh prawns? Frozen prawns work perfectly, just thaw and drain them really well first.
Ingredient Substitutes
- Butter: Use margarine if needed, though butter gives the best flavour.
- Dried thyme: Italian seasoning or oregano works too.
- Cajun spice: Use peri peri seasoning or smoked paprika with cayenne.
- Dried chili peppers: Chili flakes work well.
