🍽️ Recipe At A Glance

  • Cook Time: 8–12 minutes (depends on prawn size)
  • Difficulty: Easy
  • Servings: 4 (serving 5–6 oz cooked prawns each)

Why This Recipe Works:

This Baked Garlic Butter King Prawns recipe guarantees restaurant-worthy results at home because it’s rooted in smart, proven cooking science. First, briny king prawns are patted truly dry—this key step helps them sear and prevents steaming. They’re tossed in rich garlic butter, locking in moisture while maximizing flavor, then roasted hot and fast so they stay *juicy* in the center, not tough.

The short roast at 400–425°F hits the sweet spot: high heat for caramelized, golden edges, but brief enough (8–12 minutes) to preserve their springy bite. A final 1–2 minute broil ramps up browning and aroma. Bright lemon juice and zest cut through the richness, while the butter delivers gloss and a silken mouthfeel. And with an instant-read thermometer—pulling at 120–125°F for perfect doneness—you’ll hit the mark every time. It’s easy garlic butter shrimp meets lemon garlic butter prawns, with results that impress at any table.

Baked Garlic Butter King Prawns: Easy 20-Minute Recipe For Busy Weeknights 19

Ingredients You’ll Need for

  • 1 lb (450 g) raw king prawns
    • peeled and deveined, tail-on preferred (16/20–21/25 count per lb for large/jumbo)
  • 4 tablespoons (56–60 g) unsalted butter
    • softened (or sub ghee/olive oil for dietary tweaks)
  • 4 garlic cloves
    • fresh, finely minced or microplaned
  • 2 tablespoons freshly squeezed lemon juice
  • 1 teaspoon finely grated lemon zest
  • 1 teaspoon kosher salt
  • 1/2 teaspoon freshly ground black pepper
  • 1 tablespoon finely chopped fresh parsley
  • Optional flavor boosters:
    • 1/2 teaspoon chili flakes (for heat)
    • 1 teaspoon anchovy paste or fish sauce (for umami, gluten-free if needed)
    • 1 tablespoon extra-virgin olive oil (for drizzling or swapping butter)

Scaling Tip: Increase all ingredients proportionally; use 1 tablespoon butter per ~112 g (4 oz) prawns for batch size changes. Do not over-salt—reduce salt by 25% if using salted butter.

💡 Ingredient Pro Tip: For the freshest garlic flavor, microplane (not chop) the cloves—no bitterness, just a sweet, mellow bite. For maximum citrus aroma, zest the lemon *before* juicing.

Step-by-Step Cooking Instructions:

  1. Thaw and Prep the Prawns:
    • If frozen, thaw king prawns overnight in the fridge or quick-thaw in a colander under cold water for 20–30 minutes. Pat dry thoroughly with paper towels.
    • Remove shells (leave tails on for presentation if desired). Devein (cut along the back, remove the black vein).
  2. Preheat & Prepare Butter Mixture:
    • Preheat your oven to 400°F (200°C) and set a rack to center position. If using a rimmed baking sheet or large cast-iron skillet, place it in the oven now to preheat for a better sear.
    • In a small saucepan, melt unsalted butter over low heat. Add minced garlic and lemon zest, gently warming for 1–2 minutes until aromatic. Remove from heat and stir in lemon juice and optional anchovy/fish sauce for umami.
  3. Marinate:
    • In a bowl, toss prawns with garlic butter mixture, kosher salt, black pepper, and chili flakes if using. Let stand 10–20 minutes (do not marinate longer or prawns lose moisture).
  4. Arrange Prawns & Bake:
    • Carefully remove hot sheet/skillet from oven. Arrange prawns in a single layer, not overlapping (for best caramelization).
    • Pour any remaining garlic butter over the top.
  5. Roast:
    • Bake for 8–11 minutes for king prawns (21/25–16/20 count), or 10–12 minutes for jumbo/giant prawns. Halfway through, rotate pan once for even heat.

  6. Check Doneness:
    • Insert an instant-read thermometer into the thickest part—remove from oven at 120–125°F (49–52°C). Prawns should be opaque, pink, and feel just-firm.
    • Let rest 2–3 minutes on the tray to finish cooking to about 130°F (carryover heat for juiciness).
  7. Broil (Optional):
    • To brown the tops, broil 1–2 minutes, watching closely—edges will caramelize and juices sizzle.
  8. Finish & Serve:
    • Toss with chopped parsley and a final squeeze of lemon juice. Spoon pan juices over the prawns. Serve immediately.
👨‍🍳 Chef’s Hack: For easy cleanup, line the hot pan with parchment just before arranging prawns—or finish in a cast-iron skillet for a tableside sizzle.

Recipe Variations & Dietary Modifications:

  • Keto/Low-Carb Version: This recipe is already keto as written! For extra flavor, swap in 1 tsp anchovy paste or double the butter. Omit bread or rice when serving.
  • Vegan/Vegetarian Version: Substitute king oyster mushrooms or extra-firm tofu (pressed & sliced) for prawns, and use vegan butter. Roast as directed, reducing cook time to 7–8 minutes.
  • Gluten-Free Version: Baked Garlic Butter King Prawns are naturally gluten-free—just confirm your fish sauce or any additions are wheat-free. Serve with gluten-free grains or low-carb sides.
  • Dairy-Free Version: Replace butter 1:1 with ghee, high-quality olive oil, or coconut oil. Ghee gives a buttery finish without dairy proteins—use the same quantity as butter, and cook exactly as written.
  • Spicy/Mild: Add extra chili flakes or a pinch of cayenne with the marinade for heat, or omit them for a milder crowd-pleaser.
  • Herbed Variation: Add 1 tablespoon chopped fresh dill, tarragon, or basil in place of (or with) parsley.

Tip: If you reduce or switch the fat (e.g. swap some butter for olive oil), the flavor becomes brighter and lighter, and texture stays just as juicy. For extra protein, toss in shelled edamame or serve with a side of Lemon Balm Cauliflower Rice.

Serving Suggestions & Pairings:

These Baked Garlic Butter King Prawns shine brightest when plated simply—spoon pan juices over the top, stack prawns artfully on a platter, and scatter with freshly chopped parsley, dill, or microgreens. Add a few lemon wedges for squeezing and watch your guests swoon.

Pairings are endless, but here are my favorites for a blissfully fast, gourmet-style meal:

  • Classic Sides: Crispy Air Fryer Smashed Potatoes, steamed asparagus, or lemon-herb rice
  • Keto/Low-Carb: Garlic zoodles (spiralized zucchini), cauliflower purée, or a leafy green salad
  • Bread Lovers: Grilled sourdough, gluten-free focaccia, or garlic toast for soaking up the buttery sauce
  • Wine Pairing: Dry Chardonnay, Sauvignon Blanc, or a sparkling wine—clean flavors, citrus notes
  • Cocktail: Try a classic gin and tonic with a twist of lemon zest

Storage & Meal Prep Tips:

Baked Garlic Butter King Prawns are at their best fresh, but here’s how to store and prep for busy nights:

  • Storage (Refrigerate): Place cooled prawns and sauce in an airtight container, refrigerate up to 48 hours. Keep sauce and prawns separate if possible for best reheating.
  • Freezing: Freeze cooked or raw (marinated) prawns in a single layer on a tray; once solid, transfer to vacuum-seal or airtight container. Use within 3 months for best texture. Thaw overnight in fridge before reheating or cooking.
  • Reheating: Warm gently in a skillet with a splash of water/lemon over low heat, or bake at 300°F (150°C) for 6–8 minutes, just until warmed through (avoid microwaving, which toughens shellfish). Do not exceed 140°F.
  • Make-Ahead Sauce: Garlic lemon butter can be mixed and refrigerated up to a week, or frozen as “flavor cubes” for instant seafood nights.

FAQ:

How do I keep Baked Garlic Butter King Prawns from getting rubbery?

Can I use frozen prawns for Baked Garlic Butter King Prawns?

Yes! Just thaw them first, either in the fridge overnight or in cold water for 20–30 minutes. Pat thoroughly dry for best caramelization and to avoid a watery bake.

Can I scale this Baked Garlic Butter King Prawns recipe up for a crowd?
