Seafood Macaroni and Cheese

Introduction

The kitchen smelled like butter and sea air as I pulled this out of the oven—warm, cheesy steam that makes you slow down. Right away I knew this Seafood Macaroni and Cheese would be a keeper: creamy noodles, sweet crab, and just-cooked shrimp. This always takes me back to Sunday dinners. For a little twist, I sometimes pair it with a crisp salad and a cold glass of white wine to balance the richness. Also, if you like a similar twist on mac, try this honey pepper chicken mac and cheese for weekday comfort.

Ingredients You’ll Need

• 2 cups dry Macaroni
• 6 oz Claw Crab Meat
• 8 oz Shrimp, peeled and deveined
• 8 oz Sour Cream
• 4 Tablespoons Butter
• 2 Tablespoons Flour
• 1 Spring Onion
• 1 can Evaporated Milk
• 8 oz block Sharp White Cheddar Cheese
• 4 oz block Mozzarella Cheese
• 1/4 cup Panko Bread Crumbs
• Salt, to taste
• Black Pepper, to taste
• Paprika, for color

Chef notes:

• Use fresh crab when possible — sweeter results.
• Unsalted butter helps control final salt.
• Panko gives a light, crunchy top.

How to Make It

1. First, preheat the oven to 350°F and boil salted water for the macaroni. Cook pasta al dente per package, then drain well and return to a large bowl.
2. Next, stir in the sour cream until every noodle glows with creaminess, then fold in the claw crab meat gently.
3. Meanwhile, melt butter in a skillet over medium heat and add the shrimp; listen for the satisfying sizzle. Cook until just opaque, about 2–3 minutes per side, then remove, let cool briefly, chop slightly, and add to the macaroni.
4. Then, finely chop the spring onion; sauté the white parts in the same pan until tender and fragrant. Sprinkle the flour over the onions, stir, and let it toast for about one minute—this builds a nutty base.
5. Slowly pour in the evaporated milk while whisking; keep stirring until the sauce thickens and coats the back of a spoon. Gradually stir in the grated cheddar until smooth and silky.
6. Now, pour the hot cheese sauce over the macaroni and seafood, season with salt and black pepper, and stir until combined. Taste and adjust seasoning.
7. Finally, transfer the mixture to a well-buttered baking dish, top with shredded mozzarella and panko, dust lightly with paprika, and bake 20–25 minutes until golden and bubbling at the edges. Let rest a few minutes before serving.

Kitchen Tips (From My Kitchen)

1. Time-saver: Use pre-shredded cheese in a pinch, but grate fresh for the creamiest melt.
2. Common mistake + fix: Overcook shrimp—stop at opaque to avoid rubbery bites; remove early and finish in sauce.
3. Simple variation: Stir in a pinch of Old Bay or smoked paprika for extra warmth.

Serving Ideas

• Serve as a cozy weeknight dinner with steamed green beans.
• For brunch, plate smaller portions alongside a crisp arugula salad.
• Bring to a potluck; it travels well and reheats safely.
• Pair with a lemony slaw or crusty bread; garnish with chopped chives or parsley.
• Try with a meatier side like crockpot tortellini and sausage for a hearty meal.

Storing & Leftovers

• Fridge: Store in an airtight container for 3–4 days.
• Freezer: Freeze portions for up to 2 months; thaw overnight in fridge.
• Reheat: Warm in a 325°F oven covered until heated through to keep it creamy.
  
  Leftover idea: Turn cold portions into a quick bowl with a fried egg on top.
