How to Make Seafood Mac & Cheese: The Best Ever Creamy Recipe You’ll Love
Step 1: Prep the Pasta and Baking Dish
Start by preheating your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish so nothing sticks later. Then, cook your elbow macaroni according to package directions until just al dente—they’ll absorb a bit more sauce as baking finishes them off, so don’t overcook. Drain them and set aside while you tackle that dreamy cheese sauce.
Step 2: Make a Velvety Cheese Sauce
Place a large saucepan over medium heat and melt the butter. Sprinkle in the flour and whisk constantly for a minute or two, creating a smooth, lightly golden roux. Gradually pour in the milk and heavy cream, whisking as you go to keep everything silky—watch as it thickens after a few minutes. Now, stir in the Dijon mustard, Old Bay seasoning, garlic powder, salt, and pepper. This mix will fill your kitchen with mouthwatering aromas!
Step 3: Add the Cheeses for Maximum Creaminess
Move the sauce off the heat and toss in the cheddar, mozzarella, and Parmesan cheeses. Stir until everything melts into a glorious, stretchy, smooth sauce. This is the true heart of Seafood Mac & Cheese: The Best Ever Creamy Recipe You’ll Love—don’t rush it, and watch as it transforms before your eyes.
Step 4: Fold in Seafood and Flavor Bursts
Gently fold in the lump crab meat, chopped cooked shrimp, and green onions. This is where the magic happens—soon, every bite will be packed with both tender noodles and generous bits of perfectly seasoned seafood. Toss in the drained macaroni and stir everything together until each tube is coated in luscious cheese sauce.
Step 5: Assemble and Top with Crunch
Pour your seafood mac mixture into the prepared baking dish, spreading it evenly. In a small bowl, combine the panko breadcrumbs with the olive oil or melted butter for your crisp topping, then scatter it over the surface. This not only locks in flavor and moisture but also delivers a golden, crunchy crown that contrasts all the creaminess underneath.
Step 6: Bake to Bubbling Perfection
Slide the dish into the oven and bake for 20 to 25 minutes, until the top is golden brown and the edges are bubbling with anticipation. Let it rest for 5 to 10 minutes before serving, as this gives the cheese just enough time to set up perfectly—hot, oozy, and so satisfying.
How to Serve Seafood Mac & Cheese: The Best Ever Creamy Recipe You’ll Love

Garnishes

Freezing

Reheating

FAQs
Can I use other types of seafood?
Absolutely! While crab and shrimp make a classic combo, scallops, lobster, or firm white fish can all work beautifully. Just make sure your seafood is cooked (if needed) and roughly chopped for easy mixing and eating.
Is there a way to make this dish spicier?
If you crave more heat, add a pinch of cayenne pepper, hot sauce, or diced jalapeño to the cheese sauce. The creamy base absorbs spice really well, so it’s easy to customize to your preferred level.
Can I make Seafood Mac & Cheese: The Best Ever Creamy Recipe You’ll Love ahead?
Yes! You can assemble the whole thing (minus the breadcrumb topping) a day in advance, then add the crumbs and bake when you’re ready. The chilling time actually helps the flavors blend even more.
Which cheese melts best for this recipe?
