Ingredients

450g (1 lb) large prawns, peeled and deveined with tails on


85g (6 tablespoons) butter


6 cloves garlic, minced (18g)


2 tablespoons (30 ml) lemon juice


1 tablespoon (15 g) fresh parsley, finely chopped


1 teaspoon (5 g) sea salt


1 teaspoon (5 g) black pepper


1/2 teaspoon (2.5 g) red chilli flakes


1 tablespoon (15 ml) vegetable oil


Lemon wedges for serving

Cooking Instructions

Step 1:
Preheat your BBQ to medium-high heat (200°C/400°F). While heating, pat 450g (1 lb) prawns dry with paper towels.

Step 2:
In a small saucepan on the BBQ or stovetop, melt 85g (6 tablespoons) butter over medium heat. Add 6 cloves (18g) minced garlic and cook for 1 minute until fragrant.

Step 4:
Thread prawns onto skewers, using two parallel skewers per row of prawns to prevent spinning and make flipping easier. Place about 4-5 prawns per skewer set.

Step 5:
Brush prawns with 1 tablespoon (15 ml) vegetable oil and place on the preheated grill.

Step 6:
Cook for 2-3 minutes per side until prawns turn pink and opaque, brushing with the garlic butter mixture halfway through cooking.

BBQ Garlic Prawns

What side dishes and accompaniments pair best with these BBQ garlic prawns?

These BBQ garlic prawns make a stunning centrepiece that pairs beautifully with several complementary sides. For a complete meal, serve with a fresh green salad dressed with lemon vinaigrette to echo the citrus notes in the prawns. Grilled vegetables like asparagus, zucchini, or capsicum work brilliantly as they can cook alongside the prawns in just minutes. For a heartier option, serve over cauliflower rice to keep it low-carb, or with fragrant jasmine or coconut rice to absorb the delicious garlic sauce. Fresh crusty bread is perfect for mopping up the flavourful butter or oil mixture. For a Mediterranean twist, pair with a Greek-style cucumber, tomato, and feta salad. Mango salsa makes a refreshing sweet-tangy counterpoint to the garlicky prawns, while a simple herb-infused couscous provides a light but satisfying base. For a dinner party presentation, serve the prawns atop a creamy avocado and lime puree with fresh coriander garnish for a restaurant-quality dish that comes together in minutes.

How do I know when my BBQ garlic prawns are perfectly cooked?

Perfect prawns should be cooked just until they turn opaque and pink—this typically takes only 2-3 minutes per side at 200°C (400°F). The biggest mistake is overcooking, which results in tough, rubbery prawns. Look for these visual indicators: the prawns should change from translucent grey to opaque pink-white, and they'll naturally curl into a loose "C" shape. If they curl into a tight "O" shape, they're overcooked. For food safety, the internal temperature should reach 63°C (145°F), but since prawns cook so quickly, visual cues are usually more practical. If you're unsure, cut one open—the flesh should be opaque throughout with no translucent centre.

Can I substitute the butter in the traditional recipe for dietary needs or health reasons?

Absolutely! The low-calorie version already demonstrates one excellent substitution using avocado oil instead of butter, reducing the fat content by 50% (from 14g to 7g) and calories by 32% (from 215 to 145) while maintaining a 95% protein content. For dairy-free needs, use olive or avocado oil as in the low-cal version. For a heart-healthy option that retains richness, try ghee (clarified butter) which has reduced lactose and casein. Coconut oil will add a subtle tropical flavour that pairs nicely with the prawns, though it won't significantly reduce calories. If you enjoy the buttery flavour but want fewer calories, try a 50/50 mix of butter and olive oil. Each of these substitutions maintains the recipe's keto-friendly, high-protein profile while accommodating various dietary preferences.

What's the best way to prevent prawns from sticking to the BBQ grates?

To prevent sticking, follow these key techniques: First, ensure your BBQ grates are properly cleaned and preheated to 200°C (400°F) before cooking. Next, thoroughly pat the prawns dry with paper towels—this is crucial as moisture creates steam that causes sticking. Using the double-skewer technique mentioned in the recipe is excellent as it keeps prawns flat and makes them easier to flip. Before placing on the grill, brush both the prawns and the grates with oil (the 1 tablespoon called for in the recipe). When it's time to flip, if you feel resistance, wait a few more seconds—prawns will naturally release when they've developed a proper sear. For extra insurance, you can lightly spray the grates with a high-heat cooking oil just before placing the prawns down, or use a well-seasoned cast iron plate over your grill grates.

How does this recipe fit into various nutrition plans, and what are the key nutritional benefits?

These BBQ garlic prawns are extremely versatile nutritionally. The traditional version features an 83% protein/fat ratio with minimal carbs (1.4% of calories), making it excellent for keto and low-carb diets. The low-calorie version offers an impressive 55% protein, 43% fat ratio with the same low carbs, suitable for higher-protein plans. Both versions are gluten-free and dairy-free (low-cal version only). Prawns are nutritional powerhouses containing selenium (nearly 100% of daily needs per serving), which supports thyroid function and acts as an antioxidant. They're also rich in iodine for metabolic health, vitamin B12 for energy production, and provide approximately 19-20g of complete protein per serving, supporting muscle maintenance with all essential amino acids. The omega-3 fatty acids in prawns (approximately 540mg per serving) offer anti-inflammatory benefits, though not as high as fatty fish like salmon.
