The prawns are the star—wild-caught from a trusted seafood counter is ideal, but high-quality frozen (thawed properly) works nearly as well. Look for 16/20 count per pound for even cooking and impressive presentation. Most Whole Foods or local fishmongers will have what you need. Avoid pre-cooked or previously frozen prawns that smell fishy or have a slimy texture.

No fresh lemons? Bottled lemon juice at half the amount works in a pinch, but fresh zest is non-negotiable—it carries the citrus aroma. If you’re out of smoked paprika, regular paprika plus a pinch of cayenne adds similar depth. For a brighter herb profile, swap oregano for fresh dill or thyme. The olive oil should be something you’d eat plain—no old, bitter bottles.

Marinated prawns keep in the fridge for up to 12 hours—longer and the citrus starts to cure them. Cooked prawns are best eaten immediately but will hold in a warm oven for 20 minutes. Leftovers? Refrigerate for 1-2 days and use in tacos or salads.

Step-by-Step Instructions for Simple Grilled Prawns

Master the technique for perfectly charred prawns with bright citrus notes.

Step 1: Prepare the Marinade

In a large bowl, whisk together 2 tbsp Fresh Lemon Juice, 1 tbsp Lemon Zest, 3 tbsp Extra-Virgin Olive Oil, 3 cloves minced Garlic Cloves, 1.5 tsp Kosher Salt, 1 tsp Freshly Ground Black Pepper, 0.5 tsp Smoked Paprika, and 0.5 tsp Dried Oregano. I crush the dried oregano between my fingers as I add it to release its aromatic oils.

This marinade balances acidity, fat, and spices to both tenderize the prawns and build layers of flavor. The smoked paprika adds depth without overpowering the natural sweetness of the seafood.

Step 2: Marinate the Prawns

Add the 1.5 lb Large Prawns to the marinade, ensuring each piece is fully coated. I prefer to leave the tails on for presentation and easier handling on the grill. Let them marinate at room temperature for 15-20 minutes.

Don’t exceed 30 minutes of marinating time—the acid in the lemon juice will begin to “cook” the prawns, turning them mushy. The prawns should develop a slight sheen as they absorb the flavors.

Step 3: Grill to Perfection

Preheat your grill to medium-high heat. Lightly oil the grates to prevent sticking. Remove the prawns from the marinade (reserve any leftover for basting if desired) and arrange them on the grill in a single layer, leaving space between each piece for even cooking.

Grill for 2-3 minutes per side until the prawns turn opaque and pink with defined grill marks. The prawns are done when they curl into a loose “C” shape and the flesh feels firm to the touch. Avoid overcooking—they’ll continue to cook slightly off the heat.

Step 4: Finish and Serve

Transfer the grilled prawns to a serving platter. Sprinkle with 0.25 cup chopped Fresh Parsley and, if desired, 0.25 tsp Red Pepper Flakes for a subtle heat. The parsley adds a fresh, herbal note that brightens the dish.

Serve immediately while hot. The prawns should have a smoky char from the grill with a tender, juicy interior. Any reserved marinade can be boiled for 1 minute and drizzled over the top for extra flavor, though I often skip this to keep the dish light and simple.

Dietary Considerations for This simple grilled prawns

Pescatarian Friendly

This dish is naturally pescatarian, making it perfect for seafood lovers. The 1.5 lb Large Prawns provide lean protein without any meat, and the marinade uses only plant-based ingredients. I often serve this at gatherings where guests follow pescatarian diets. 💪

Gluten-Free Safe

All ingredients in this recipe are inherently gluten-free. Just ensure your Kosher Salt and spices are certified gluten-free if you have celiac disease. I always double-check labels at the local butcher shop to be safe.

Dairy-Free Naturally

There’s no dairy in this creation, so it’s suitable for lactose-intolerant diners. The Extra-Virgin Olive Oil and citrus provide all the richness needed. I’ve never missed the butter when grilling prawns this way.

Low-Carb Option

With practically no carbs, this fits perfectly into keto or low-carb meal plans. Each serving has less than 2g net carbs. I pair it with a simple green salad to keep the meal light and satisfying.

Shellfish Allergy Warning

Since prawns are shellfish, this dish is not safe for anyone with a shellfish allergy. For a similar grilled experience, try swapping in chicken tenders with the same marinade. Always confirm allergies with your guests beforehand.

Nut-Free Preparation

This recipe contains no nuts, making it safe for those with nut allergies. Just ensure your grill hasn’t previously cooked nut-containing foods. I clean my grill grates thoroughly with a brush before cooking. 🌿
