This Seafood Mac and Cheese recipe is made with crab, shrimp, and macaroni pasta. This is the perfect, simple cheesy casserole to add to any spread. Add Old Bay Seasoning for an additional kick of flavor!
What Type of Seafood to Use
I love to use shrimp and jumbo lump crab in this recipe. You can also use scallops, lobster, mussels, or pretty much whatever you like.
What Type of Shrimp to Use
Shrimp can be found at the grocery store in a few different ways. There is raw, pre-cooked, raw and frozen, deveined, tails on, tails off, etc.
I never use pre-cooked shrimp. There is an obvious difference in taste due to the lack of quality. The shrimp is cooked and then frozen and you have to cook it/warm it up again. This usually overcooks the shrimp. Raw shrimp only takes minutes to make, just buy it raw.
Can You Use Frozen Shrimp? How to Thaw
You should thaw it first. You can thaw frozen shrimp in a bowl of cold water for 20 minutes.
Do You Keep the Tails on the Shrimp?
This is completely up to you and is a matter of preference. Often the tails are left on for presentation purposes only. The shrimp simply looks nicer and will have a nice curve to it when the tails are left on.
Leaving the tail on is often inconvenient when it comes to devouring the meal!
What Type of Crab to Use
I use lump crab meat. You can find it in the refrigerated meat section of the grocery store. Lots of people use imitation crab meat, sometimes called krab meat. You can use that if you wish, it’s also sometimes easier to find.
Imitation crab is processed fish meat. It is seafood and comes from surimi that has been deboned and minced into a paste. It does not contain crab. Crab extract is sometimes added for flavor.
Substitutions and Additional Add-In Ideas
- Caramelized Onions
Can You Make it Ahead
If you’re making this for a crowd, I wouldn’t make it ahead the night before. This is a dish that’s best served fresh while the cheese is still soft and gooey. After making it, I leave it in the oven on warm and covered in foil. You can, because the dish does reheat. It’s just served best when fresh.
How to Store It
You can store leftovers in the fridge, tightly covered for 3-4 days.
How to Reheat it
The best way to reheat it is in the air fryer on 350 degrees for 4-5 minutes or until warm. You can also use the oven at the same temperature. Heat until warm. You can use the microwave, but it doesn’t result in the best texture in my opinion.

Always purchase your cheese in block form and shred or grate it yourself. You can also use a food processor. Pre-shredded cheese has preservatives and potato starch to keep it from going bad quickly. These additives don’t melt nicely and the dish won’t be as creamy. Grate your own cheese. It makes a huge difference.
Feel free to add more cheese as you deem necessary. To make this a really creamy and cheesy dish, I often add 1 to 1 1/2 cups of additional shredded cheddar. I typically add this additional cheese to the cheese sauce to make it really thick.
If you’re using baby shrimp, you probably don’t need to slice them into chunks.
You can whatever milk you choose in the recipe.
If you’re making this for a crowd, I wouldn’t make it ahead. This is a dish that’s best served fresh while the cheese is still soft and gooey. After making it, I leave it in the oven on warm and covered in foil.
I also wouldn’t prep it in advance. This will ruin the texture of the cheese.
