Tips for Success
Cook the macaroni just until al dente because it will continue cooking in the oven.
Use freshly shredded Colby Jack and cheddar whenever possible for a smoother cheese sauce.
Pat the seafood dry before adding it to prevent excess moisture from thinning the casserole.
Fold the seafood into the sauce gently to keep the shrimp, crab, and lobster pieces intact.
Don’t overbake the casserole because seafood can become tough and dry when exposed to excessive heat.
Allow the casserole to rest for 5–10 minutes after baking so the sauce can thicken slightly.
Instructions
Step 1 Prepare the Oven
Preheat the oven to 375°F (190°C).
Lightly grease a 9 × 13-inch baking dish.
Step 2 Cook the Macaroni
Bring a large pot of salted water to a boil.
Add the macaroni and cook according to the package directions until al dente.
Drain thoroughly and set aside.
Step 3 Prepare the Seafood
If using pre-cooked seafood, ensure the shrimp, crab, and lobster are properly drained.
Place them in a bowl and gently toss with the lemon juice and seafood seasoning.
Set aside.
Step 4 Prepare the Cheese Sauce
Melt the butter in a large saucepan over medium heat.
Whisk in the flour and cook for approximately 1 minute.
Gradually add the milk and heavy cream while whisking continuously.
Cook for approximately 4–6 minutes, stirring frequently, until the mixture begins to thicken.
Add the garlic powder, onion powder, paprika, dried parsley, salt, and black pepper.
Step 5 Melt the Cheese
Reduce the heat to low.
Add the cubed Velveeta gradually, stirring until completely melted.
Add the shredded Colby Jack and cheddar.
Continue stirring until the sauce becomes smooth and creamy.
Avoid boiling the sauce.
Step 6 Combine the Pasta and Seafood
Add the cooked macaroni to the cheese sauce.
Stir gently until the pasta is completely coated.
Fold in the shrimp, crab meat, and lobster.
Mix carefully so the seafood remains in substantial pieces.
Step 7 Assemble the Casserole
Transfer the seafood mac and cheese to the prepared baking dish.
Spread evenly.
Combine the panko breadcrumbs, melted butter, Parmesan cheese, and parsley in a small bowl.
Sprinkle the mixture evenly over the top.
Add the remaining Colby Jack cheese.
Step 8 Bake
Cover the casserole loosely with aluminum foil.
Bake for 20 minutes.
Remove the foil and continue baking for another 10–15 minutes, until the cheese is bubbling and the topping is golden.
For an extra-crispy topping, broil for 1–2 minutes, watching carefully.
Step 9 Rest and Serve
Remove the casserole from the oven.
Allow it to rest for 5–10 minutes.
Garnish with fresh parsley and serve with lemon wedges.
Serve warm.
