10 Delicious Low Carb Baked Fish Recipes

Low carb diets are more popular than ever. But after a while, eating chicken, pork, and beef gets boring real fast. If you’d like to switch things up at dinnertime, why not try fish instead? Although eating fish can be a challenge since it’s so often served up bread and fried, it doesn’t have to be. Fortunately, there are plenty of ways to bake fish and make it low carb.

Fish are an excellent source of omega-3 fatty acids, are packed with protein, and are quick and easy to bake. Here are some tips on our favorite fish choices as well as 10 no-fail baked fish recipes that are low carb and keto friendly.

What Fish is Best for a Keto Diet?

Since keto focuses a lot on healthy fats, you’ll find that the most recommended fish are ones that are high fat. Popular favorites include:

  • King (chinook) salmon – 6 oz. rings in at 304 calories, 17.7 grams of fat, 33.9 grams of protein, and 0 carbs
  • Sardines – 3.5 oz. has 208 calories, 11.5 grams of fat, 0 carbs
  • Anchovies – a 3 oz. serving has 111 calories, 4 grams of fat, 17 grams of protein, and 0 carbs
  • Mackerel – a 3 oz. serving has 170.9 calories, 8.6 grams of fat, 21.9 grams of protein, and 0 carbs

That said, many of us (myself included) have to watch our fat intake when low-carbing. For that reason, we should usually choose lean fish like tilapia, cod, haddock, tuna, mahi-mahi, and trout, among others.

We’ll include recipes for both some fatty fish and lean fish in the list below to provide a few options for everyone.

Which Fish is Low Carb?

All fish have zero (or nearly zero) carbs, so any of them are suitable for a keto diet. If you love seafood, that’s great news for you!

Just keep in mind any other dietary restrictions you may have. For example, if you’re on a low fat, low carb diet, avoid fish that are higher in fats like salmon and sardines.

Is Oven-Baked Fish Healthy?

Oven-baked fish is as healthy as you want to make it. If you keep the oil to a minimum, avoid creamy sauces (unless it fits your macros) and avoid rolling it in breadcrumbs, then yes, it’s usually healthy.

Tasty Baked Fish Recipes for a Low Carb Diet

Baked Cod with Garlic and Herbs

Those new to seafood dishes will enjoy this baked cod recipe. Cod has a very mild flavor and is often called the chicken of the sea for that reason. The tender, flaky cod is marinated with olive oil, soy sauce, lemon zest, garlic, and fresh herbs for at least half an hour or up to 8 hours. Then, it’s baked in the oven until it’s perfectly cooked.

Serve this fish over cauliflower rice or zoodles to keep it low carb. A serving of green veggies like asparagus on the side will pair nicely, too.

The marinade works for other mild whitefish as well as salmon.
