When preparing this recipe, you might need to visit the supermarket for a few key ingredients.

Ingredients For Seafood Lasagna With Crab And Shrimp
Lasagna noodles: Wide, flat pasta used as the base layers for the lasagna.
Crab meat: Sweet, tender meat from crabs, adding a rich seafood flavor.
Shrimp: Small, succulent shellfish that are peeled, deveined, and chopped for this recipe.
Ricotta cheese: A creamy, mild cheese that adds richness to the lasagna layers.
Mozzarella cheese: A stretchy, melty cheese that provides a gooey texture.
Parmesan cheese: A hard, aged cheese that adds a sharp, nutty flavor.
Olive oil: Used for sautéing the garlic and seafood, adding a subtle fruity flavor.
Garlic: Adds a fragrant, savory note to the seafood mixture.
Marinara sauce: A tomato-based sauce that ties all the flavors together.
Technique Tip for Making Seafood Lasagna
When preparing the seafood mixture, ensure that the shrimp and crab meat are cooked just until the shrimp turns pink and opaque. Overcooking the seafood can result in a rubbery texture, which can detract from the overall dish. Additionally, when layering the lasagna, make sure to spread the ricotta mixture evenly to create a balanced flavor and texture in each bite. Using a spatula can help achieve a smooth and even layer.

How to Store or Freeze Your Seafood Lasagna
Allow the seafood lasagna to cool completely at room temperature before storing. This helps prevent condensation, which can make the lasagna soggy.
For short-term storage, transfer the lasagna to an airtight container or cover the baking dish tightly with plastic wrap or aluminum foil. Store in the refrigerator for up to 3-4 days.
For long-term storage, cut the lasagna into individual portions. Wrap each portion tightly in plastic wrap, then place them in a freezer-safe bag or container. Label with the date and contents.
To reheat refrigerated lasagna, preheat your oven to 350°F (175°C). Place the lasagna in an oven-safe dish, cover with aluminum foil, and bake for about 20-25 minutes or until heated through. If you prefer a crispy top, remove the foil for the last 5 minutes of baking.
To reheat frozen lasagna, you have two options:
- Thaw in the refrigerator overnight, then follow the reheating instructions for refrigerated lasagna.
- Bake directly from frozen. Preheat your oven to 350°F (175°C). Place the frozen lasagna in an oven-safe dish, cover with aluminum foil, and bake for about 60-75 minutes. Remove the foil for the last 10-15 minutes to allow the top to become bubbly and golden.
If you prefer using a microwave, place a portion of lasagna on a microwave-safe plate. Cover with a microwave-safe lid or another plate to retain moisture. Heat on medium power for 3-5 minutes, checking and rotating halfway through, until heated thoroughly.
For best results, avoid reheating seafood lasagna multiple times. Reheat only the portions you plan to consume immediately to maintain the quality and texture of the dish.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover seafood lasagna in an oven-safe dish. Cover it with aluminum foil to prevent it from drying out. Bake for 20-25 minutes or until heated through.
For a quicker method, use the microwave. Place a slice of seafood lasagna on a microwave-safe plate. Cover it with a microwave-safe lid or another plate to retain moisture. Heat on medium power for 2-3 minutes, checking halfway through to ensure even heating.
If you have an air fryer, preheat it to 350°F (175°C). Place a slice of seafood lasagna in the air fryer basket. Heat for 5-7 minutes, checking halfway through to ensure it doesn't dry out.
For stovetop reheating, place a slice of seafood lasagna in a non-stick skillet over medium-low heat. Add a splash of water or marinara sauce to the pan and cover with a lid. Heat for 10-15 minutes, checking occasionally to ensure even heating.
To retain the creamy texture of the ricotta mixture and mozzarella cheese, consider reheating in a double boiler. Place the seafood lasagna in a heatproof dish and set it over a pot of simmering water. Cover and heat for 15-20 minutes, ensuring the water doesn't touch the bottom of the dish.
