Step 1

Preheat oven to 220°C/430°F (all oven types).

Step 2

Pour wine and half the butter into 9 x 13" / 22 x 33cm baking pan (see Note 3 if using glass). Place in oven for 10 minutes to reduce.

Step 3

Toss prawns with remaining butter, garlic, lemon juice, salt and pepper. Butter may harden - that's ok.

Step 4

Mix Crunchy Topping ingredients.

Step 5

Remove pan from oven. Add prawns - spread out in single layer, but snug.

Step 6

Top with Crunchy Topping. Bake 12 minutes.

Step 7

Flick to broiler/grill on high, broil for 1 - 2 minutes (max) to brown top a bit more.

Step 8

Sprinkle with parsley. Serve immediately with lemon wedges and crusty bread to mop up the incredible sauce!
