Why You'll Love These Keto Fish Recipes

I put this list together because I got tired of seeing the same three salmon recipes everywhere. These are 25 recipes I actually love, and they cover so much ground.

Salmon, tilapia, codfish, catfish, tuna - they are all here, and they are all keto friendly. Most fish have zero to one net carb, so you can eat well without stressing your macros at all.

I love how many cooking styles are in this collection. Crispy air fryer fish, baked whole catfish, spicy soups, fish cakes, even tuna stir fry over cauliflower rice. You will find something for a quick Tuesday dinner and something impressive enough for guests.

A lot of these recipes bring bold, spiced-up flavors you won't find on most keto blogs. Peppered croaker fish and African fish stew are two I keep coming back to. Once you try fish cooked with those deep, layered spices, plain baked fish feels like a downgrade.

How to Prepare Fish

There are so many ways to prepare fish. You can fry them in a pan with a little oil and spices for flavor. Be careful when flipping them so they don't break apart.

You can also fry them in an air fryer which is so easy and convenient to use. This method also uses less oil.

Baking fish in an oven with spices and herbs is a great way for fish to come out tender with loads of flavor. Other ways of preparing fish include grilling, sautéing in a sauce, or making it in a pressure cooker.

Frequently Asked Questions

Is fish low carb?

Yes, all fish are naturally low carb. Most have zero to one net carb per serving, which makes them one of the best proteins you can eat on keto. You really can't go wrong with fish.

What is the best fish for keto?

Honestly, any fish works. I personally love salmon, catfish, tilapia, and codfish because they are easy to find, easy to cook, and hold up well to bold seasonings. Salmon is especially great because it is also high in healthy fats, which is exactly what you want on keto.

Are keto fish recipes hard to make?

Not at all. Most of the recipes in this collection come together in 30 minutes or less. Some take even less time than that. The air fryer recipes especially are done before you know it.

What can I season fish with on keto?

So many things. I use spices like paprika, garlic powder, cayenne, and cumin a lot. You can also use a store-bought fish seasoning, fresh herbs, or a marinade with lemon and olive oil. The key is to not be shy with the seasoning because fish can handle a lot of flavor.

How many carbs are in fish?

Most plain fish have zero carbs. The net carb count goes up slightly depending on the seasoning or sauce you use, but even then most of these recipes stay under 3 net carbs per serving.
