Before you start
Before you begin, ensure all ingredients are measured and ready. Prepare your baking dish by lightly greasing it with butter or non-stick spray to ensure easy serving.
Have your shrimp peeled, deveined, and patted dry with paper towels. This preparation allows the cooking process to flow smoothly, ensuring the sauce is prepared at the ideal consistency before the final bake.

Instructions
Pasta and Shrimp Preparation
- Prepare Pasta and ShrimpBoil a large pot of salted water and cook the macaroni until al dente. Drain well in a colander. In a separate pan, cook the shrimp until they turn pink and opaque. The shrimp must reach an internal temperature of 145°F (63°C) to be safely consumed.Look for shrimp are opaque and pinkSafe temperature 145°F (63°C) internal temperature (shellfish)Tip Do not overcook the pasta as it will soften further in the oven.
The pasta should be cooked to al dente, meaning it still has a slight bite, while the shrimp should be opaque and pink. Ensure the shrimp are handled safely and cooked through to 145°F (63°C) before being removed from the heat. Drain the pasta thoroughly so no excess water dilutes the richness of your cheese sauce.
Combining Ingredients
- Combine IngredientsIn a large mixing bowl, combine the cooked macaroni and the cooked shrimp. Add the cheese sauce and stir until the pasta and shrimp are evenly coated with the sauce.Look for pasta is fully coated in cheese sauceTip Ensure the sauce is at room temperature before mixing to ensure even distribution.
The mixture is ready when it has thickened significantly and the cheese sauce coats every noodle and shrimp evenly. The cheese should be completely incorporated, and the texture should be smooth and consistent.
Check for seasoning at this stage, adding a touch more salt or pepper if you prefer a bolder flavor profile before combining.
Final Bake and Assembly
- Assemble and BakePreheat your oven to 375°F (190°C). Pour the mixture into a 9x13 inch baking dish. Bake in the preheated oven for 15 to 20 minutes, or until the cheese is bubbling and the top is golden brown. Let the dish rest for 5 minutes before serving.Look for cheese is bubbling and goldenTip Use a metal spoon to scoop a generous portion to ensure you get plenty of shrimp.
The final dish should look golden and inviting, with the cheese sauce bubbling vigorously. The aroma should be rich and savory. Once taken out of the oven, the mixture should hold its shape slightly when scooped. Allow it to rest for a few minutes to ensure the sauce thickens to the perfect consistency for serving.
Common mistakes
A common mistake is using a sauce that is too thin, which results in a runny dish rather than a creamy, cohesive one. Another error is overcooking the pasta; remember that it will continue to soften as it bakes in the cheese sauce.
Finally, ensure the shrimp are not overcooked during the initial searing phase, as they will spend additional time in the oven.
How to tell it’s done
The dish is ready when the cheese sauce is actively bubbling around the edges of the dish and the top has developed a beautiful, golden-brown crust. The shrimp, having been pre-cooked to 145°F (63°C), will be perfectly heated through.
Avoid baking for too long, as this can cause the cheese sauce to separate or the pasta to become mushy. Always allow the dish to rest for at least 5 minutes before serving to allow the sauce to set slightly.
