Garlic Shrimp Mac and Cheese

Step 1: Preheat the broiler or oven grill to high.

Step 2: Mix the breadcrumb topping ingredients together.

Step 3: Heat the oil and melt 1 tablespoon of the butter in a large, deep skillet or heatproof pot over high heat. Add the shrimp and sprinkle with pepper. Cook for 1 minute, then add the garlic and cook for another minute, until the shrimp have changed color but are not fully cooked. Transfer them to a bowl.

Step 4: Reduce the heat to medium and melt the remaining butter. Add the flour and cook for 1 minute. Slowly pour in the milk, stirring as you go. Once it is incorporated and smooth, using a whisk if needed, stir in the seasonings, then add the water.

Step 5: Once the liquid is hot, add the macaroni. Cook for 8 minutes, stirring regularly, until it is almost cooked through. Remove the pot from the heat.

Step 6: Stir in the cheeses, then add the shrimp. Taste and adjust the salt if needed. The mixture should still be saucy; the sauce will be absorbed and thicken more in the next step.

Step 7: Sprinkle the breadcrumb mixture over the top. Place the pot under the hot grill for 2–3 minutes, until the topping is golden.

Step 8: Sprinkle with parsley if desired and serve immediately.
