Why Seafood Mac and Cheese?
I’ve always had a deep love for seafood—there’s something about the fresh, oceanic flavor that brings a sense of luxury and sophistication to any dish. On the other hand, mac and cheese holds a special place in my heart as the ultimate comfort food, satisfying the soul with its creamy texture and rich cheese flavor. Combining the two? It was a natural next step for me in the kitchen.
The result is a dish that’s comforting yet elegant, hearty yet refined. Whether you’re using shrimp, lobster, or crab, the addition of seafood introduces a delightful burst of flavor, making this mac and cheese stand out from the usual. Let’s dive into how to create this irresistible dish from scratch.
Ingredients:
For the Seafood:
- 1 lb shrimp, peeled and deveined (or lobster, crab, or scallops)
- 1 tbsp olive oil or butter
- 1 tsp garlic powder
- 1 tsp paprika
- Salt and pepper to taste
For the Mac and Cheese:
- 1 lb elbow macaroni or your favorite pasta
- 4 tbsp butter
- 4 tbsp all-purpose flour
- 2 cups whole milk
- 1 cup heavy cream
- 2 cups shredded sharp cheddar cheese
- 1 cup shredded Gruyère cheese
- 4 oz cream cheese (softened)
- 1 tsp Dijon mustard (optional)
- 1 tsp garlic powder
- ½ tsp onion powder
- Salt and freshly ground black pepper to taste
- 1 cup panko breadcrumbs (optional, for topping)
- Fresh parsley or chives for garnish (optional)
Instructions:
1. Prepare the Seafood:
- Cook the Seafood: In a medium skillet, heat 1 tablespoon of olive oil or butter over medium-high heat. Add the seafood (shrimp, lobster, crab, or scallops), and season with garlic powder, paprika, salt, and pepper. Sauté for 2-3 minutes (for shrimp) or until the seafood is cooked through and opaque. Remove from heat and set aside.
- For shrimp: Cook until pink and slightly curled.
- For lobster: Cook until the meat is opaque and firm.
- For crab: If using fresh crab, cook until the meat is just tender. If using canned crab, simply warm it up.
- For scallops: Sear each side for 2-3 minutes, ensuring a golden-brown crust while keeping the inside tender.
- Chop the Seafood: Once cooled, chop the seafood into bite-sized pieces if needed and set aside for later use in the mac and cheese.
2. Cook the Pasta:
- Bring a large pot of salted water to a boil. Add the macaroni and cook according to the package instructions until al dente, about 8-10 minutes. Drain and set aside.
3. Make the Mac and Cheese Sauce:
- Prepare the Roux: In a large pot, melt 4 tablespoons of butter over medium heat. Once melted, whisk in 4 tablespoons of flour. Continue to whisk for 2-3 minutes until the mixture becomes golden and bubbly.
- Add the Dairy: Slowly pour in 2 cups of whole milk and 1 cup of heavy cream, whisking constantly to prevent lumps. Continue to cook for another 5 minutes until the mixture thickens slightly.
- Melt the Cheese: Lower the heat and add the 2 cups of shredded sharp cheddar, 1 cup of shredded Gruyère, and 4 oz of cream cheese. Stir until the cheese is completely melted and the sauce is smooth.
- Season the Sauce: Add 1 teaspoon of Dijon mustard (optional), 1 teaspoon of garlic powder, ½ teaspoon of onion powder, and salt and pepper to taste. Stir to combine.
4. Combine the Pasta and Seafood:
- Mix the Pasta and Sauce: Add the drained pasta to the cheese sauce, stirring gently to coat each piece of pasta with the creamy sauce.
- Fold in the Seafood: Gently fold in the prepared seafood, distributing it evenly throughout the mac and cheese. Be careful not to break up the seafood too much.
5. Optional: Bake the Mac and Cheese (For a Crispy Top)
- Preheat your oven to 350°F (175°C). If you prefer a crispy topping, transfer the seafood mac and cheese to a greased baking dish.
- Top with Breadcrumbs: Sprinkle the top with 1 cup of panko breadcrumbs for added crunch and texture.
- Bake: Place the dish in the oven and bake for 20-25 minutes, or until the top is golden brown and crispy.
6. Serve and Garnish:
- Once baked (if you chose to bake it), remove from the oven and let it sit for 5 minutes before serving.
- Garnish with freshly chopped parsley or chives for a pop of color and extra flavor.
7. Enjoy!
Serve your seafood mac and cheese hot, with a side of fresh salad or garlic bread if desired. Enjoy the creamy richness of the mac and cheese paired with the succulent, flavorful seafood.
Storage and Reheating:
If you have leftovers, store them in an airtight container in the fridge for up to 3 days. To reheat, simply microwave individual portions or warm the mac and cheese in the oven, adding a little extra milk or cream to restore its creamy texture.
Frequently Asked Questions (FAQ) – Seafood Mac and Cheese
1. What is the best seafood to use in mac and cheese?
You can use shrimp, lobster, crab, scallops, or a combination of these. Shrimp and crab add a sweet, delicate flavor, while lobster and scallops bring a rich, buttery taste.
2. Can I use frozen seafood?
Yes! Just thaw it completely in the refrigerator overnight or under cold running water before cooking. Pat dry to remove excess moisture to prevent a watery dish.
3. What cheese works best for seafood mac and cheese?
A mix of sharp cheddar, Gruyère, and cream cheese provides a creamy, flavorful base. You can also use smoked Gouda, Monterey Jack, or Parmesan for extra depth.
4. Can I make seafood mac and cheese ahead of time?
Yes! Assemble the dish without baking, cover it tightly, and refrigerate for up to 24 hours. When ready, bake as directed, adding a few extra minutes to the cooking time.
5. How do I prevent the cheese sauce from becoming grainy?
To ensure a smooth sauce:
- Use low heat when melting cheese.
- Shred cheese fresh from the block (pre-shredded cheese contains anti-caking agents).
- Stir constantly and avoid overheating the sauce.
6. Should I bake seafood mac and cheese?
Baking is optional. If you love a crispy, golden crust, sprinkle panko breadcrumbs on top and bake for 20-25 minutes at 350°F. If you prefer it extra creamy, skip baking and serve right from the stovetop.
7. Can I make this recipe gluten-free?
Absolutely! Use gluten-free pasta and substitute all-purpose flour with gluten-free flour or cornstarch to thicken the sauce. Also, use gluten-free breadcrumbs if baking.
