When we think of fish tacos, most of us probably imagine filets of white fish that have been breaded and deep-fried before they’re stuffed into a tortilla or shell. While delicious, they can pack in a lot of carbs, fat, and grease.

These low-carb salmon tacos are a whole new way to enjoy fish tacos! Flaky, tender filets are topped with a bright salsa featuring corn, avocado, and jalapeño that’s bursting with bright, acidic flavor. They’re so refreshing!

And to top it off, this entire meal can be ready to eat in less than half an hour. Simply rub the salmon filets with oil and seasoning before placing them in the oven. Then, while the fish bakes, toss your salsa ingredients together, and that’s it! When the salmon is ready, all you have to do is assemble your tacos and dig in.

For a nutritious meal that’s quick to make and still delivers big on flavor, you have to try these low-carb fish tacos. They might become a weekly staple on your menu!

Ways to customize this recipe

This recipe is relatively low in carbs as-is. If you’re looking for a keto-friendly dish, you can omit the corn and use low-carb tortillas or lettuce wraps.

Have a little more room for carbs in your diet? Feel free to add black beans for some extra fiber! I highly recommend making your own low-sodium no-soak beans for maximum flavor.

Prefer to enjoy this fiesta of flavors as a bowl instead? Ditch the tortillas and serve your ingredients over low-carb cauliflower rice!

You can also play around with your ingredients based on tastes, preferences, or simply what you have in your kitchen. Don’t like spicy? Swap out the jalapeño for chopped bell pepper. Prefer yellow onion? Use that instead. Want to top everything with sour cream or shredded cheese? Go for it!

Storage

I recommend storing any leftover salmon and leftover salsa in separate airtight containers in the refrigerator. The fish will stay fresh for up to three to four days and the salsa will keep for up to a week.

When you’re ready to eat, gently reheat the salmon in the microwave or the oven. Once warmed through, top with your salsa and enjoy!
