20 Easy Keto Fish Recipes for a Light Dinner

If you think keto is too restrictive, you have to try these easy keto fish recipes. I bet you’ll find them just as bright, tasty, and filling as any carb-filled meal.

Like most types of meat, fish is an excellent source of protein, and it’s full of vitamins, minerals, and antioxidants to boot.

But unlike many keto diet staples, fish isn’t that fatty. So, you can enjoy these recipes on just about any diet – low-carb, low-calorie, you name it!

These keto fish recipes couldn’t be easier to whip up, and they’re pretty darn delicious, too.

1. Air Fryer Salmon Teriyaki

Many people assume that the keto diet strictly forbids anything fried. But that’s not true at all; you just need the right tools for the job.

In this case, that tool is an Air Fryer.

With only five ingredients – keto teriyaki sauce, salmon filets, xanthan gum, toasted sesame seeds, and scallions – you can have this tender, flaky salmon ready in just 15 minutes. 

2. Keto Low-Carb Salmon With White Wine Sauce

Of course, if you don’t have an Air Fryer, you can always pan-sear the fish instead. It tastes just as impressive and stays wonderfully juicy and flavorful.

This recipe, in particular, has a ton of flavor because you’ll cook the fish with garlic, butter, white wine, lemon juice, capers, and more.

It takes longer than the Air Fryer salmon recipe, but it’s every bit as delicious.

(Seriously, though, if you don’t have an Air Fryer, you should invest in one ASAP. They’re pretty awesome.)

3. Keto Creamy Lemon Garlic Salmon

It’s hard to believe that anything covered in a thick and creamy sauce could be considered “diet food,” but this creamy lemon garlic salmon is 100% ketogenic-friendly.

The rich garlic and lemon sauce is unbelievably rich, and despite how decadent the dish looks, it has only six carbs per serving.

4. Alaskan Salmon with Butter Cream Sauce and Avocado

This simple 15-minute salmon recipe combines salmon, butter, shallots, dry white wine, heavy whipping cream, an avocado, salt, and pepper for a tasty dish that’s packed with protein.

This one is especially great if you’re managing macros and need more fat because the heavy cream-based sauce really piles it on.

5. No-Fail Keto Baked Salmon with Cilantro Pesto

The cilantro lovers in your life will go nuts for this baked salmon recipe.

The fish is mild and flaky, but the cilantro pesto comes in with a wallop of flavor that’ll have you craving more. 

Best of all, you’ll need fewer than ten ingredients to make it, and you can have it on the table in 30 minutes or less!

Serve it with some roasted garlic cabbage or a crunchy keto slaw.

6. Keto Asian Glazed Salmon

Looking for a keto fish recipe with an Asian flair? How about this sticky, sweet, and savory salmon?

The combination of lime juice, ginger, and garlic is light, bright, and perfect. One bite, and you’ll think this came from your favorite Chinese restaurant.

And even with the glaze, each serving has only a single carb! 

7. Parmesan Baked Cod Recipe (Keto, Low Carb, GF)

Let’s change gears and step away from salmon for a minute.

This baked cod recipe is cheesy, garlicky, and soooo buttery. It’s also keto-friendly and gluten-free. 

It takes a little over half an hour to make, has only two carbs, and boasts a whopping 37 grams of protein. 

Serve it with one of these yummy keto sides for a more complete meal.

8. Breakfast Everything Bagel Keto Salad

You’re probably wondering how you can enjoy an everything bagel when bagels are strictly a no-go on the keto diet.

Well, you can’t. Sorry.

But you can enjoy a delectable and satisfying salad overflowing with all those yummy flavors, thanks to the addition of everything bagel spice. 

The recipe also calls for smoked salmon, avocado, cucumbers, cherry tomatoes, dill fronds, and more. 

Beyond that, just keep the ingredients low-carb, and add whatever you like.

9. Keto Parmesan Crusted Flounder Fish

This 20-minute flounder recipe should be a go-to in any keto-friendly household. It’s quick and easy to make, requires the simplest ingredients, and tastes phenomenal. 

Plus, since you’ll cover it in parmesan and blanched almond flour, it actually has a nice, crispy crust to enjoy, as well.

This fish is super flavorful and would be the perfect addition to one of these incredible Indian keto recipes.

10. Air Fryer Parmesan Crusted White Fish (Keto)

White fish is what most people go for, especially those who don’t like fishy fish.

Whether you use tilapia or something else, it has such a mild, non-fishy taste that it’s an easy one to love.

Use this recipe and your Air Fryer to make some of the most flavorful, well-seasoned fish possible. The whole process shouldn’t take more than 25 minutes. 

11. Keto Parmesan and Pecan Crusted Halibut

With its fantastic, decadent crust and bold taste, this halibut is a must-try for anyone.

Instead of using breadcrumbs, you’ll make your own from parmesan, crushed pecans, and garlic.

You’ll love the crazy flavor that’s packed into every bite, and the soft, flaky insides are a delightful contrast against the crispy crust. 

12. Fish Pie with Cauliflower Mash (Low-Carb) 

I know what you’re thinking: this looks too casserole-like to be a low-carb dish!

But I swear it’s low-carb and keto-approved.

It’s all down to the mashed cauliflower heads, which make all the difference when counting carbs.

However, thanks to the sour cream, butter, cheddar, chives, nutmeg, and salt, the taste is still incredible – like cheesy mashed taters.

So the next time you want a good home-cooked Southern-style meal but don’t want to knock yourself out of ketosis, you can’t beat this easy cauliflower recipe.

13. Crispy Keto Salmon Patties

Crispy salmon patties are something we can all enjoy, keto diet or not!

Each of these is packed with green onions, Cajun seasoning, jalapeños, and more, so you might want to make extra!

Serve these to your family, and I bet they won’t even know it’s “diet” food.

And if you like bright, colorful, and spicy food, why not try some of these heavenly keto Mexican recipes?

14. Keto Tuna Casserole

Here’s another comforting casserole you can enjoy guilt-free – even on the ketogenic diet. It takes 30 minutes to whip up, and half the casserole has only two net carbs! 

Did you read that?! Half of this entire dish has just two net carbs.

Sorry, I just think that’s incredible and deserves to be repeated!

Plus, it features half a cup of Gruyère cheese, one of the most delicious cheeses. That alone makes up for the casserole not having any noodles.

15. Tomato Avocado Tuna Melt

One thing that’s hard to escape is the lack of carbs on keto. Usually, that’s not an issue, especially when you have cauliflower to fill the hole.

But how can anyone give up sandwiches?

Luckily, with this recipe, you don’t have to. It might not be exactly the same, but it’s super satisfying and should curb those cravings.

All you need to do is swap the bread for juicy tomatoes.

Everything else – from the tuna and pickles to the mayo and cheese – stays the same. So, if you’re in the mood for a deli favorite, give this recipe a try.

16. Keto Battered Fish – Perfect Crispy Low-Carb Batter

How do you enjoy traditional battered fish with crispy, crunchy outsides and soft, flaky insides without eating too many carbs?

With almond flour and protein powder, of course!

I won’t lie; it doesn’t taste exactly the same as non-keto battered fish, but it’s close enough. 

And once you dip it in the keto lemon tartar sauce, you’ll never know the difference.

17. Keto Tuna Cakes

Keto tuna cakes are just like you’d expect, only they’re made with almond flour instead of all-purpose. That means they’re just as crispy, tender, and herby as standard tuna cakes.

The fact that they have two net carbs per serving doesn’t hurt, either.

18. Salmon In Roasted Pepper Sauce

This is one of those meals that’s all about the sauce.

Don’t get me wrong; the salmon is delicious! But the sauce? Amazing.

It’s creamy, thick, buttery, cheesy, and peppery. There’s absolutely nothing about it you won’t love. 

19. Hearty Keto Seafood Chowder

High in fat and low in carbs, keto seafood chowder is the ideal recipe for anyone on the keto diet.

It has a wonderfully smooth and creamy consistency, and the flavor is overflowing with umami goodness.

It takes less than an hour to make and even features crunchy pieces of salty bacon too. Serve it with a leafy green salad or even some low-carb bread for a complete meal.

20. Easy Keto Baked Tilapia

This scrumptious baked tilapia takes 25 minutes to prepare and bake, has less than two net carbs per serving, and features 34.5 grams of protein.

Does it get any better than that?

It’s so simple to make and has an incredible cheese and herb flavor that even non-fish lovers can appreciate. It’s one the whole family will love.
