Easy Seafood Lasagna
Fun fact: Nearly one in four Americans are Catholic. And since Catholics can’t eat meat on Fridays during Lent – but can eat fish – that adds up to a lot of fish being sold during this season. Stores all over the country have great sales on seafood, and normally pricey treats like shrimp and crabmeat are available at bargain prices.

So basically, even for those of us who aren’t Catholic, this is a great time of year to try out new seafood recipes. And it’s healthy, too!
So, in honor of this season of seafood, I decided to try a fish-based version of that classic Italian treat, lasagna.

How to Make Seafood Lasagna:
First, I swapped out the ground beef for a mixture of luscious shrimp and crabmeat. Then, since a hearty red sauce would drown out the more delicate flavors of the seafood, I replaced it with a basic white sauce with a touch of parmesan. And I skipped the zesty basil and oregano in favor of chopped parsley, which complements the fishy flavors.
Eating lasagna this way will make you see this classic recipe with new eyes. It’s a deliciously different twist on your grandma’s lasagna that will make you fall in love with this old favorite all over again.

Made this a day ahead and baked it the next evening. This was so delicious! Served it with Caesar salad and homemade French bread. Husband said not to lose the recipe. Thank you for sharing.
I made a delicious twist on the shrimp dish! I added some cooked spinach to the mixture and swapped out the crab for tilapia (it was more budget-friendly). Everyone loved it!
Love the swaps you made. I’ll have to try that next time I make this!
Could I make this the day before ?
Yes. Cover and refrigerate until the next day.
I made this and it was great! I never cook my noodles just make sure to cover the bottom of the dish with sauce and the top layer is also covered with sauce and cheese. It does have to bake covered about 10 minutes longer and then uncovered but it’s a great time saver.
Anyone use a jar white sauce instead of making your own?
