Step 1

Preheat broiler/grill on high.

Step 2

Mix together Breadcrumb Topping.

Step 3

Heat oil and melt 1 tbsp butter in a large, deep skillet or heatproof pot on the stove over high heat.

Step 4

Add shrimp, sprinkle with pepper, then cook for 1 minute. Add garlic and cook for another minute until the shrimp has changed colour but not fully cooked.

Step 5

Transfer to bowl. Turn heat down to medium.

Step 6

Melt remaining butter. Add flour and cook for 1 minute.

Step 7

Pour milk in slowly, stirring as you go. Once incorporated and lump free (use whisk if needed), stir in Seasonings, then water.

Step 8

Once the liquid is hot, add macaroni. Cook for 8 minutes, stirring regularly, until macaroni is almost cooked through, then take it off the stove.

Step 9

Add cheeses and stir through, then add shrimp. Taste for salt - tweak if needed. It should be saucy (see video) - it gets absorbed. Should still be saucy at this stage - sauce gets absorbed/thickens more in next step.

Step 10

Sprinkle over breadcrumbs, then place under the hot grill for just 2 - 3 minutes until the top is golden.

Step 11

Sprinkle with parsley if desired and served immediately!
