20 Keto Seafood Casserole Recipes

Seafood Casserole is one of the favorite dinner ideas, especially on the summer day, we talk here about shrimp, salmon, crab, scallop, and other fish casseroles. I tried in this article to gather as much possible a keto version of seafood casseroles. So here’s a list of 20 Best keto seafood casserole recipes that you will absolutely love.

1. Keto Lobster Casserole

You have to give this Keto Lobster Casserole a go if you want to make the most delicious casserole in the history of casseroles. Because of how delicious this low carb supper meal is, it will quickly become a staple on your menu.

I will be the first to confess that the ingredients for this seafood casserole are on the pricier side when compared to some of my other recipes. Lobster flesh and whipped cream have a tendency to be on the costlier side of the menu. It is still a wonderful meal that should be made sometimes as a treat for the family.

2. Keto Tuna Casserole

This Keto Tuna Casserole is a dish that is reassuring, warming, and really simple to prepare. It’s prepared in the form of tuna noodle casserole using keto noodles, and it’s done in little more than 20 minutes.

This Keto Tuna Noodle Casserole will bring back memories of the classic tuna noodle casserole, but with a significant reduction in the amount of carbohydrates. Because of the use of keto noodles, the dish does, in fact, have a noodle foundation exactly like the original.

The tuna, noodles, and vegetables are mixed together in a sauce that is creamy and cheesy. There is just a tiny quantity of peas and carrots in the dish, which is not enough to raise the carbohydrate count but is enough to give it the flavor of a classic tuna noodle casserole.

3. Simple Seafood Casserole

The easiest and most delicious seafood casserole we’ve ever made is called Simple Seafood Casserole. A flavorful sauce is created as a result of the combination of garlic and cream in this dish.

This recipe for a quick seafood casserole is one of the family favorites that I get asked for the most often. We wouldn’t have any trouble eating this once a week.

This dish is typically served over rice pilaf or jasmine rice, as well as broccoli. This casserole works really well as a supper for a group of people. You may make it earlier in the day, and then when you’re ready to eat it, all you have to do is put it in the oven.

4. Shrimp and Cauliflower Rice Casserole

Anything that includes shrimp is one of my favorite foods. As well as rice. And cheese. And in a baking dish or casserole. It’s kind of like shrimp and grits, except with cauliflower rice instead of grits.

This shrimp and cauliflower rice casserole is very amazing. Because I was born and raised in the South and also spent some time in Louisiana, eating shrimp and grits is practically an obligation for me.

I am always looking for new and simple cauliflower keto dishes to try. I have adapted this recipe to be keto and low carb friendly. Because of its high nutrient density, those who consume it should monitor their macronutrient intake carefully.

When I’m not attempting to limit the amount of carbohydrates I eat, I replace the cauliflower rice with grits or regular rice. You may use lighter versions of the cheeses if it appears like there is too much richness in the dish.

5. Easy Baked Crabmeat Casserole Recipe

Try out this recipe for a baked crabmeat casserole for a dish that is both simple and delicious to make with seafood.

It resembles a quiche but does not have a crust and can be prepared with fresh, tinned, or frozen meat instead of the traditional quiche filling. Even fake crab flesh that has been finely shred can be utilized.

I would compare this crab casserole that is baked in the oven to something more akin to a super large omelette that is baked. In point of fact, for the better part of the past week, we’ve been having it for breakfast.

You may use fresh or frozen meat in this recipe if you don’t live near the water and don’t have easy access to fresh crabs. This dish might alternatively be made with crab meat that has been canned.

6. Chinese Baked Crab Delight Seafood Casserole

You may easily make your own version of the popular meal known as Chinese Buffet Seafood Bake, which is offered at a large number of Chinese Buffets all over the world.

Do you enjoy Chinese buffets a lot? They offer a wide variety of mouthwatering dishes to choose from. The seafood bake is one of the most popular dishes, and many people have requested me to reproduce it. This seafood bake requires very little effort to prepare. It is made using extremely basic components all the way through.

This recipe is really simple to make; all you have to do is mix the ingredients together, put them in a casserole dish, and bake them in the oven for approximately half an hour. Therefore, in only half an hour, you will have a great meal ready for you and your family to enjoy.

7. Salmon Casserole 

In contrast to the classic salmon casserole, which is typically loaded with carbs in the form of noodles, this variation omits the pasta and instead focuses on the ingredients that really matter.

This meaty meal gives the impression of being comfort food, yet there is none of the associated guilt. The slight sourness that comes from the goat cheese is the key ingredient in this dish’s successful battle against becoming overly heavy.

In addition, despite the fact that the casserole has a lot of moisture on its own, the crumble topping adds just the proper amount of diversity to the texture.

8. Creamy White Seafood Lasagna

This recipe for Creamy White Seafood Lasagna is simple to prepare and is stuffed with large shrimp, lobster, and lump crab meat. The most delicious sauce is the creamy cheese-filled alfredo one. This meal is available with a healthy alternative, so feel free to try it out! You won’t need to go to Olive Garden for dinner because of this!

Palimini Lasagna Sheets are fantastic and come highly recommended from me. Hearts of palm are used in the preparation of these. It is a type of food that is taken from the budding bud and inner core of some palm palms. And when it’s put into spaghetti, it has an incredible flavor!

For YEARS, zucchini noodles have been one of my go-to noodle alternatives. It came as a complete surprise to me when I tried the linguine and discovered that it outperformed my go-to zucchini noodles by a significant margin.

9. Smoked Haddock Bake

Recipe for a fast and straightforward Smoked Haddock Bake that is both tasty and healthy to one’s health. It only requires nine components, and the entire process takes about half an hour to complete. Gluten-Free. Low-Carb. Keto.

For this recipe, you’ll only need 9 basic ingredients. The majority of the necessary produce is comprised of fundamental items that are probably already a regular component of your weekly shopping.

This smokey fish meal may be ready in only 30 minutes, and only 10 minutes of that time will require your direct participation in the cooking process (the rest of the time your dish will be in the oven)!

10. Keto Fish Pie

This dinner dish for keto fish pie is simple to make and is the epitome of comfort food. The white fish, salmon, and prawns are served in a cheese sauce that is velvety, and the dish is finished off with a cheesy cauliflower mash.

The classic British recipe for fish pie calls for mashed potatoes to be used as the topping. Cauliflower, with all of its many uses, is used in this recipe for fish so that it may be classified as a low-carb dish. In addition to being a low carb choice, the creamy sauce is made with cream cheese.
