Creamy Seafood Mac and Cheese Bake Step-by-step instructions

Before you start

Before beginning this recipe, ensure that all ingredients are measured and ready to go. Grate the cheddar cheese if using a block and chop the fresh herbs. Preheat your oven broiler to high. Have your large stockpot for boiling pasta and a large mixing bowl prepared.

If using frozen shrimp, make sure they are completely thawed and patted dry with paper towels to prevent excess moisture from diluting your final cheese sauce. Having everything organized in advance makes the cooking process smooth and stress-free.

Instructions

Pasta and Shrimp Preparation

1. 1Prepare Pasta and Shrimp
   Bring a large pot of salted water to a boil. Cook the elbow macaroni according to package directions until al dente. Drain and set aside. Ensure the shrimp are cooked until opaque and pink, reaching an internal temperature of 145°F (63°C).
   Look for Shrimp should be opaque and pink.
   Safe temperature 145°F (63°C) internal temperature (shellfish)
   Tip Do not overcook the pasta, as it will continue to cook in the oven.

The pasta should be cooked to al dente, meaning it still has a slight bite, and the shrimp should be fully opaque and pink. Ensure the shrimp are cooked through to 145°F (63°C).

Drain the pasta thoroughly so no excess water remains to dilute the sauce later. Once these are ready, set them aside while you focus entirely on combining the cheese base, which requires your full attention to achieve the right consistency.

Combining Ingredients

2. 2Combine Ingredients
   In a large bowl, combine the cooked macaroni and shrimp with the prepared cheese sauce. Stir in the shredded cheddar cheese until the mixture is evenly coated and well combined.
   Look for Sauce should be thick and smooth.
   Tip Mix gently to avoid breaking the shrimp.

The mixture is ready when it is thick, smooth, and coats the pasta and shrimp evenly. When you stir the cheese into the sauce and pasta, the color should be uniform and the texture velvety. If the sauce seems too thick, you can whisk in a small splash of warm milk, but ensure it is fully incorporated before transferring to the baking dish to maintain the desired thickness.

Assembly and Broiling

3. 3Assemble and Bake
   Preheat the oven broiler. Transfer the mixture into a 9x13 inch baking dish. Place under the broiler for 3 to 5 minutes until the top is golden and bubbling. Garnish with fresh herbs before serving.
   Look for Cheese should be golden and bubbling.
   Tip Watch the casserole closely under the broiler as it can burn very quickly.

The casserole is finished when the top is golden-brown and the edges are bubbling aggressively. The aroma should be rich and savory. Watch the oven closely during the final broiling stage, as the transition from perfectly golden to burnt can happen in seconds. Once the desired crust is achieved, remove the dish from the oven and let it stand for a few minutes so the sauce thickens to the perfect serving consistency.

Common mistakes

A common mistake is adding the cheese to the sauce while it is still over high heat, which can cause the proteins to seize and the fat to separate, resulting in a grainy or oily sauce.

Another frequent error is overcooking the pasta in the boiling water; keep it slightly firm, or al dente, because the pasta will continue to absorb moisture and soften while it bakes in the oven, preventing a mushy final texture. Ensure the shrimp are not overcooked before assembly.

How to tell it’s done

The dish is considered done when the cheese sauce is hot and bubbling vigorously throughout the entire casserole. When you insert a spoon into the center, the sauce should be thick and creamy, not runny.

The shrimp must be cooked to an internal temperature of 145°F (63°C) to ensure safety and the best texture. The top should be nicely browned and crispy from the broiler. Let the dish rest for about 5 minutes before serving to allow the sauce to set slightly.

• Shellfish: 145°F (63°C) in the thickest part
