Seafood Lasagna On A Finances
This white seafood lasagna is loaded with taste from candy onions, celery, garlic, juicy little shrimp, and chopped imitation crab (although in case your finances permits, you’ll be able to splurge on recent crab or scallops and use them as a substitute!). Additionally, I sneak in a handful of spinach for coloration, splash in a bit lemon juice, and add simply sufficient Cajun seasoning to wake every part up. Then all of it will get tucked between layers of tender noodles, cottage cheese, a comfortable do-it-yourself white sauce, and loads of mozzarella on prime. It has that very same big-pan-of-comfort feeling you get from conventional lasagna, however with a creamy white sauce and a easy seafood filling that makes it really feel recent and enjoyable. This recipe for seafood lasagna can be good for meal prepping!
- Let the white sauce absolutely thicken. The butter and flour (roux) want a minute of cooking to take away the uncooked flour style, then the milk ought to be added steadily whereas whisking always. Because it heats, the sauce will thicken, and persistence is necessary! Speeding it or including the milk too rapidly retains the sauce from thickening correctly.
- Watch the broiler carefully. The toasted cheese on prime is one in all my favourite components, however it might go from golden to burnt quicker than you’d assume! I hold the dish close to the entrance of the oven and pull it out as soon as golden on prime.
- Let the lasagna relaxation earlier than slicing. Giving your creamy seafood lasagna 10-Quarter-hour to settle after baking makes such a distinction. The layers agency up, the sauce thickens only a bit, and the slices maintain collectively higher for serving.

Serving Options
I really like serving this shrimp lasagna with a easy inexperienced salad tossed in zesty Italian dressing as a result of it cuts by the richness within the nicest approach. Garlic bread or a crusty Italian loaf is a traditional pairing with lasagna, so it matches proper in with this seafood model, too. Or for a lighter household dinner, I’ll add roasted or steamed broccoli, sautéed Brussels sprouts, or air-fried asparagus.
Storage & Reheating
Preserve leftover seafood lasagna within the fridge, tightly lined or in an hermetic container, for as much as 3 days. To freeze, I like to recommend assembling the layers, however don’t bake. As a substitute, wrap the assembled lasagna in plastic and foil, and freeze it for as much as 2 months. Once you’re able to bake, let it thaw within the fridge in a single day, then prepare dinner as proven within the recipe above. Add about 15–20 minutes to the baking time because it’s beginning out chilly.
For reheating, 350°F within the oven works effectively. Cowl particular person slices with foil to maintain them moist, then warmth for about 15–20 minutes. If you happen to’re quick on time, the microwave works in fast bursts.
This white seafood lasagna may be made a day forward. Assemble it, cowl tightly, and refrigerate.
