FAQs
What seafood goes well with mac and cheese?
Shrimp, crab, lobster, scallops, and salmon work beautifully in mac and cheese. These seafood options add a sweet, delicate flavor that pairs well with the creamy, cheesy base.
Do cheese and seafood go together?
Absolutely! While some seafood dishes traditionally avoid cheese, creamy seafood pasta dishes (like lobster mac and cheese) prove that cheese and seafood can be a delicious match. The key is using mild cheeses that don’t overpower the seafood’s delicate flavors.
What mixes well with mac and cheese?
Seafood, bacon, roasted vegetables, caramelized onions, and spicy seasonings like Cajun or Old Bay add extra flavor. Topping it with crispy breadcrumbs or crushed crackers adds a nice crunch!
Do cheese and crab go together?
Yes! Crab and cheese are often paired with crab dip, stuffed mushrooms, and seafood mac and cheese. The smooth, creamy texture of melted cheese pairs beautifully with the sweetness of other ingredients, and the crab meat is ideally tender.
Top Tips for Perfecting Seafood Mac and Cheese
Want to ensure your mac and cheese turns out rich, creamy, and flavorful? Here are some helpful tips:
1. Choose the Right Cheese
A combination of cheddar, mozzarella, and Parmesan works best. Avoid pre-shredded cheese containing anti-caking agents that can make the sauce grainy.
2. Use Fresh or Frozen Seafood
Fresh seafood is always great, but frozen works too! If using frozen shrimp or crab, thaw completely and pat dry before cooking to avoid extra liquid in the sauce.
3. Don’t Overcook the Seafood
The shrimp is cooked in just a few minutes, and the crab meat is already cooked. Overcooking makes the seafood rubbery, so add it at the last minute.
4. Adjust the Seasoning
Seafood mac and cheese pairs well with Old Bay, garlic, smoked paprika, and a pinch of cayenne for a slight kick. Taste and adjust seasonings as needed.
5. Bake for a Crispy Topping
If you love a crispy top, sprinkle breadcrumbs mixed with butter over the mac and cheese before baking. This gives a delightful crunch with every bite.!
Storing and Reheating Tips
Made too much? No worries! Here’s how to store and reheat your Seafood Mac and Cheese without losing its flavor and texture.
How to Store Leftovers:
- Refrigerate: Store in an airtight container for up to 3 days.

How to Reheat:

- In the Oven: Cover with foil and bake at 350°F (175°C) for 15-20 minutes.
