This is one of my favorite go to meals when I want something that feels fancy but comes together in under an hour. The beauty of this dish is how simple it really is, yet it tastes like you've been cooking all day. Prawns are packed with protein and selenium, which supports heart health, so you're getting nutrition alongside pure deliciousness. Everything comes together on the grill and stovetop at the same time, making it perfect for weeknight dinners or impressing guests without stress. The crispy garlic potatoes are absolutely addictive, and that lemon herb butter ties everything together beautifully.

Instructions
- 1
Toss the potato cubes with 3 tablespoons of olive oil, half the minced garlic, rosemary, thyme, salt, and pepper. Spread on a baking sheet and roast at 400°F for 20-22 minutes, stirring halfway through, until golden and crispy.
Tip: Ensure potatoes are cut uniformly for even cooking.
- 2
While potatoes roast, pat the prawns dry with paper towels and season both sides with paprika, remaining salt, pepper, and chili flakes.
Tip: Dry prawns grill better and get a nicer crust.
- 3
Heat a grill pan or outdoor grill to high heat. Brush with remaining olive oil to prevent sticking.
Tip: A screaming hot grill ensures prawns cook quickly and develop a charred exterior.
- 4
Grill the prawns for 2-3 minutes per side until they turn opaque and develop light char marks. Transfer to a plate.
Tip: Don't overcook prawns as they become rubbery—they cook very quickly.
- 5
In a small skillet, melt butter over medium heat and add the remaining minced garlic. Sauté for about 1 minute until fragrant, then add lemon juice and zest.
Tip: Keep the heat moderate so the garlic doesn't burn and turn bitter.
- 6
Remove the roasted potatoes from the oven and transfer to a serving platter. Arrange the grilled prawns over and around the potatoes.
Tip: Serve immediately while everything is hot.
- 7
Drizzle the warm lemon garlic butter over the prawns and potatoes, garnish with fresh herb sprigs, and serve with extra lemon wedges on the side.
Tip: The butter creates a luxurious sauce that brings all the flavors together.
