Seafood gets a comforting twist in this creamy and cheesy Seafood Mac and Cheese topped with crunchy buttery panko bread crumbs. It’s a dish that’s impossible to resist for seafood lovers!
Shrimp and lump crab meat are surrounded by tender macaroni in a rich and decadent cheese sauce prepared with 3 cheeses… this is a seafood dinner of your dreams and is totally worth the effort.
What You’ll Need
- Shrimp
- Crab meat
- Butter (unsalted)
- Elbow macaroni
- Whole Milk
- Onions
- Garlic
- Cheeses – Cheddar, Swiss and Parmesan.
- Flour (all-purpose)
- Seasonings – Salt, pepper, Old Bay Seasoning and ground nutmeg.
- Bread crumbs – Italian seasoned panko bread crumbs. My grocery store was out of Italian seasoned panko bread crumbs, so I added about ½ teaspoon of Italian seasoning to my plain panko bread crumbs.
How to Prepare
Following is a brief overview of how to prepare; please see the recipe card for full detailed instructions.
- Begin cooking your macaroni according to package directions (cooked 2 minutes less than al dente). Drain and rinse with cold water.
- Cook shrimp in butter until shrimp have just turned pink. Remove from heat and set aside.
- Melt butter in a 6 quart Dutch oven or large pot. Transfer 2 tablespoons of the melted butter to the bread crumbs in a medium bowl and toss to combine.
- Cook diced onions and garlic in the remaining melted butter (until onions are soft) in a 6 quart Dutch oven or large pot.
- Add flour and continue to stir until a paste is formed.
- Slowly pour in milk and stir until smooth. Bring to a simmer and cook until thickened. Season with salt, pepper, nutmeg and Old Bay.
- Remove pot from burner and stir in cheeses until smooth.
- Fold in cooked macaroni, shrimp and crab meat.
- Transfer to a 3 quart baking dish that has been sprayed with cooking spray.
- Sprinkle evenly with bread crumbs. Bake for 15 to 20 minutes, or until bread crumbs are golden and sauce is bubbling around edges.
Serve with a garden salad for a complete meal!
How to Store
Allow to reach room temperature and store in an airtight container in the fridge for up to 3 days. When reheating, you’ll probably need to add a couple of tablespoons of milk, as the macaroni continues to absorb the sauce.
Recipe Variations
- Swap out the shrimp or crab meat for your favorite seafood (such as cooked lobster and/or bay scallops).
- Substitute one or more of the cheeses with your favorite cheese, such as Gruyere.

Awesome recipe
Easy fast to deliver
thank you
It came out soooo good . I appreciate the recipe. After reading the instructions I did decide to season my shrimp (added crawfish) and season the milk while simmering for more of a Cajun spicy taste ( Cajun, garlic pepper, red pepper flakes, cayenne, and paprika). Everything else was on point and perfect, panko bread crumbs was a hit . Thanks !!!!
