Seafood Mac and Cheese Ingredients
Craft this comforting dish with fresh flavors!
For the Pasta
• Elbow Macaroni – The classic base for holding the creamy cheese sauce; feel free to swap in cavatappi for a fun twist.
For the Cheese Sauce
• Unsalted Butter – Essential for making the roux; margarine can be used if you’re out of butter.
• All-Purpose Flour – Thickens your cheese sauce beautifully; gluten-free flour is a great alternative.
• Whole Milk – Creates a rich bechamel base; low-fat or non-dairy milk can accommodate different dietary needs.
• Heavy Cream – Adds indulgent creaminess; half-and-half serves as a lighter option if preferred.
• Dijon Mustard – Infuses depth of flavor into the sauce; yellow mustard can stand in if necessary.
• Old Bay Seasoning – Brings a coastal flair; substitute with Cajun seasoning for a different twist.
• Garlic Powder, Salt, Black Pepper – Season to taste; adjust these spices according to your preference.
• Sharp Cheddar Cheese – Offers a tangy kick as the primary cheese; Monterey Jack works well for a milder flavor.
• Gruyère Cheese – Contributes to the creaminess; you can use Swiss cheese if you’d like.
• Parmesan Cheese – Lends a nice salty touch; Pecorino Romano is a suitable substitute.
For the Seafood
• Shrimp – Use fresh or frozen, ensuring they are peeled and deveined for convenience.
• Lump Crab Meat – Add sweetness and texture; imitation crab is a budget-friendly alternative.
• Scallops – Tender morsels that elevate the dish; feel free to omit if you prefer a simpler version.
• Olive Oil or Butter – For cooking the seafood, keeping it from sticking while adding flavor.
For the Topping
• Panko Breadcrumbs – For that irresistible crispy crust; regular breadcrumbs work, but they alter the texture.
• Melted Butter – Mix this with breadcrumbs for a golden, crispy topping that everyone loves.
This Seafood Mac and Cheese is your ultimate comfort food, so get ready to enjoy every cheesy bite!
Step‑by‑Step Instructions for Seafood Mac and Cheese
Step 1: Cook the Pasta
Bring a large pot of salted water to a boil and add the elbow macaroni. Cook the pasta until it’s al dente, usually about 7-9 minutes, while stirring occasionally. Once cooked, drain the pasta in a colander and set it aside, ensuring it doesn’t stick together as you prepare the creamy sauce.
Step 2: Sauté the Seafood
In a large skillet over medium heat, warm a tablespoon of olive oil or butter. Add the shrimp and scallops, cooking them for 2-3 minutes until they turn opaque. Lightly season with salt and pepper, and if using crab, fold it in gently afterward. Once done, remove the seafood from the skillet and set aside.
Step 3: Make the Roux
In the same skillet, melt 2 tablespoons of unsalted butter over medium heat. Once melted, whisk in 2 tablespoons of all-purpose flour to create a roux, stirring continuously for about 1-2 minutes until it’s golden. This will serve as the base for your cheese sauce, so keep an eye on it to prevent browning.
Step 4: Create the Cheese Sauce
Gradually pour in 2 cups of warmed whole milk and 1 cup of heavy cream while whisking constantly. Continue to cook this mixture until it thickens, which should take about 4-5 minutes. Stir in the Dijon mustard, Old Bay seasoning, garlic powder, salt, and pepper for flavor, creating a deliciously rich base for your Seafood Mac and Cheese.
Step 5: Add the Cheeses
Remove the saucepan from the heat and immediately add in 1 cup each of shredded sharp cheddar and Gruyère cheese. Stir until the cheese melts completely into a creamy sauce. This step is vital for ensuring your mac and cheese is deeply flavorful, so take your time mixing it all together.
Step 6: Combine Pasta and Seafood
Carefully fold in the cooked elbow macaroni and the sautéed seafood into the cheese sauce. Use a spatula to mix everything gently, making sure each piece of pasta is coated with the rich, cheesy goodness. The Seafood Mac and Cheese should have a luscious consistency at this point.
Step 7: Prepare for Baking
Preheat your oven to 375°F (190°C). Lightly grease a baking dish with butter or cooking spray to prevent sticking. Pour the creamy mac and cheese mixture into the dish, spreading it evenly. This sets the stage for a beautifully baked dish that is ready to shine.
Step 8: Add the Topping
In a small bowl, mix 1 cup of panko breadcrumbs with 2 tablespoons of melted butter. Sprinkle this mixture generously over the Seafood Mac and Cheese for a crispy topping. This added layer will provide a delightful crunch once baked, making your dish even more irresistible.
Step 9: Bake to Golden Perfection
Place the baking dish in your preheated oven and bake for 20-25 minutes, or until the top is golden-brown and the cheese is bubbly. Keep an eye on it as the timer approaches; you want that perfect crispy top to give your Seafood Mac and Cheese a beautiful finish.
Step 10: Rest and Serve
Once baked to perfection, remove the dish from the oven and allow it to rest for about 5 minutes. This helps the flavors meld together beautifully. Serve warm and enjoy this comforting, indulgent Seafood Mac and Cheese that’s sure to be a hit with family and friends!

Expert Tips for Seafood Mac and Cheese
• Fresh Cheese Only: Use freshly shredded cheese for the best melt and flavor; pre-shredded varieties often contain anti-caking agents that can affect creaminess.
• Dry the Seafood: Ensure your shrimp and scallops are patted dry before cooking to prevent excess moisture, which can make the Seafood Mac and Cheese watery.
• Adjusting Thickness: If you prefer a creamier texture, consider serving the dish straight from the pot rather than baking it, which enhances its indulgent quality.
• Breadcrumb Substitutes: While panko breadcrumbs create an ideal crunch, regular breadcrumbs can also be used; just remember, they yield a slightly different texture.
• Layer of Flavor: Don’t shy away from seasoning—taste as you go! Adjusting the Old Bay seasoning and salt can elevate the overall flavor profile dramatically.
• Customizable Ingredients: Feel free to swap seafood based on what’s available or what you love, making this dish as unique to your taste as possible.
Make Ahead Options
These Seafood Mac and Cheese are perfect for busy home cooks looking to save time without sacrificing flavor! You can assemble the entire dish up to 24 hours in advance, simply preparing everything through the mixing step and tightly covering the baking dish with foil or plastic wrap before refrigerating.

To maintain quality, be sure to let the dish sit at room temperature for about 30 minutes before placing it in the oven. Finally, bake according to the original instructions and enjoy a gourmet comfort meal that feels just as indulgent as when you made it fresh!

Seafood Mac and Cheese Recipe FAQs
What type of seafood is best for this dish?
Absolutely! A combination of shrimp, crab, and scallops creates a delightful flavor profile. However, you can customize based on your preferences—feel free to swap in lobster, mussels, or even omit the scallops for a simpler take. Just ensure any seafood you choose is fresh or properly thawed if frozen.
How should I store leftover Seafood Mac and Cheese?
You can store your delicious Seafood Mac and Cheese in an airtight container in the fridge for up to 3 days. Be sure to let it cool completely before sealing it to maintain freshness. For optimal results, reheat gently before serving; I often find reheating on the stovetop with a splash of cream helps restore its creamy texture.
Can I freeze Seafood Mac and Cheese?
Yes, you can absolutely freeze this comforting dish! Wrap it well in plastic wrap or store it in a freezer-safe container for up to 2 months. When you’re ready to enjoy it again, thaw in the refrigerator overnight and reheat in the oven at 350°F (175°C) for about 25-30 minutes until heated through, adding a touch of cream will help revive its creaminess.
What if my cheese sauce turns out lumpy?
If your cheese sauce curdles or appears lumpy, don’t worry! This can happen if the heat is too high or the cheese was added too quickly. To salvage it, try whisking vigorously to break up the lumps. You can also add a splash of warm milk while stirring over low heat to smooth it out. Next time, ensure you let the cheese melt slowly off the heat for a creamy finish.
Are there any dietary considerations to keep in mind?
Yes! If you’re cooking for someone with shellfish allergies, you may want to stick to just crab or opt for a seafood alternative like chicken. Also, for lactose sensitivity, consider substituting whole milk and heavy cream with non-dairy milk options and a lactose-free cheese. It’s wonderful how adaptable this Seafood Mac and Cheese can be!
