I’m always looking for seafood dinner ideas. As a lover of shrimp, crab, and just about all of it….why not make a casserole from scratch and load it with all of my favorites?!
The white cream sauce in this recipe is rich and decadent. If you are familiar with my other recipes using white sauce, this is the same….with a little kick from an additional ingredient.
What Type of Noodles to Use
For regular lasagna, you can use no-boil, oven-ready or standard boiled noodles.
Low Carb Lasagna Noodles
I recommend and love Palimini Lasagna Sheets. They are made with hearts of palm. It’s a vegetable harvested from the inner core and growing bud of certain palm trees. And it tastes darn good when made into pasta!
I’ve been a lover of zucchini noodles FOR YEARS. I was totally shocked to find that when I tried the linguine, it blew my normal zucchini noodles out of the water.
What Type of Seafood to Use
I use wild-caught seafood. Studies have shown that farm-raised typically has more contaminants. The following are used in this recipe:
- Lobster Tails
- Real Lump Crab Meat
You can also use:
- Imitation Crab
- Any cooked and chopped fish
How to Make Seafood Lasagna
- Boil the noodles in accordance with the package instructions.
- Slice the shrimp and lobster into large chunks.
- Heat a large pan on medium-high heat. Spray with cooking oil.
- Season and saute the shrimp and lobster for 2-3 minutes until pink.
- Add in the crab meat and stir. Remove and set aside.
- Add butter and garlic to the pan. Saute.
- Add in whipping cream, almond milk, dry white wine, Parmesan cheese and cream cheese. Stir.
- Add the cooked seafood back to the pan and stir.
- Layer a 9×13 baking dish with noodles. Add sauce, ricotta, and shredded cheese.
- Create another layer of sauce and cheese.
- Top with noodles and then shredded cheese.
How Many Layers Should it Have?
Lasagna needs a minimum of 2 layers to maintain the definition of a lasagna. There needs to be a sauce and noodle layer and at least 1 inner layer of filling, typically sauce + cheese as a minimum and then a top noodle layer on top of which is sauce + cheese and/or just cheese.
Is Lasagna Better with Ricotta or Cottage Cheese?
You can use cottage cheese instead of ricotta if you are looking to lower the fat and calories in the dish. Strain or blend the cottage cheese if you want the consistency to be closer to ricotta.
Why Do You Cover it With Foil?
Covering it with foil will prevent the lasagna from drying out.
Can You Make it Ahead of Time?
Yes, you can make it up to 24 hours in advance and then refrigerate. Bring the casserole to room temperature before baking.
How Long Will it Last in the Fridge
Cover and store it in the refrigerator for 3-5 days.
How to Freeze the Lasagna
When freezing, ensure the dish is tightly covered and sealed. To reheat from frozen, place the lasagna in the fridge to thaw overnight.

- You can use cottage cheese instead of ricotta if you are looking to lower the fat and calories in the dish. Strain the cottage cheese if you want the consistency to be closer to ricotta.
- Modify my recipe to suit your needs. Use whatever type of seafood you want. If you want more cheese, add more cheese. If you want more layers of lasagna, add more pasta.
- If you use less seafood, you may have excess cream sauce that you will need to reserve.
- If using the Palmini Lasagna Sheets, you can expect some moisture, water from the noodles after baking. This is normal when using vegetable pasta. The longer the lasagna sits after baking, the less of a watery mess you will have.
- Leftover palmini can be stored in a refrigerator for up to three days and no longer than a week
- You can use any type of milk you prefer. You can also use half and half. Heavy whipping cream provides the best taste.
- Do not use sweet wine in this recipe.
