- 2 tsp Dijon mustard
- 1 tsp Old Bay seasoning (or paprika + pinch cayenne)
- 1/2 tsp garlic powder
- 1/2 tsp salt (adjust to taste)

- 1 cup Gruyère cheese (shredded (or Swiss))

- 1 Tbsp olive oil or butter
- Pinch of salt & pepper
Optional topping:
- 1 cup panko breadcrumbs
- 2 Tbsp butter (melted)
- 2 Tbsp Parmesan cheese
Directions
- Cook the pasta: Bring a large pot of salted water to boil. Cook pasta until al dente according to package directions. Drain and set aside.
- Cook the seafood: In a large skillet, heat olive oil or butter over medium heat. Add shrimp and scallops, cooking 2–3 minutes per side until just opaque. Stir in crab gently. Season lightly with salt and pepper. Remove from heat.
- Make the cheese sauce: In a large saucepan, melt butter over medium heat. Whisk in flour and cook for 1–2 minutes to form a roux. Slowly whisk in warm milk and cream until smooth. Stir in Dijon, Old Bay, garlic powder, salt, and pepper. Simmer gently until slightly thickened, about 5 minutes. Remove from heat and stir in cheddar, Gruyère, and Parmesan until melted and creamy.
- Combine: Add cooked pasta and seafood to the cheese sauce. Stir until everything is coated.
- Bake (optional): Preheat oven to 375°F (190°C). Transfer mixture to a buttered 9×13-inch baking dish. Mix panko with melted butter and Parmesan, sprinkle over the top. Bake uncovered for 20 minutes, until golden and bubbly.
How to Serve Seafood Mac and Cheese
Serve your Seafood Mac and Cheese hot from the oven for the best experience. This dish is hearty enough on its own, but you can pair it with a side salad or garlic bread for a complete meal. Sprinkle some extra parsley or chives on top for added freshness and color!
How to Store Seafood Mac and Cheese
If you have leftovers, let the dish cool completely before transferring to an airtight container. It will keep well in the refrigerator for up to 3 days. To reheat, simply warm it in the oven or microwave until heated through. If you bake it again, consider adding a little extra cheese or a splash of milk to keep it creamy.
Tips to Make Seafood Mac and Cheese
- Make sure not to overcook the pasta; it should be just al dente since it will bake later.
- Use fresh seafood for the best flavor. If using frozen, ensure it’s fully thawed and drained well.
- Adjust the cheese according to your preference; feel free to mix in other cheeses like Monterey Jack or Fontina for a different taste.
