How to Make Salmon Taco with Cabbage, Pickled Onions, and Avocado Recipe

Step 1: Pickle the Onions

Start by thinly slicing half a medium red onion and placing it in a medium bowl. Then, bring together cider vinegar, granulated sugar, kosher salt, and water in a small saucepan. Heat until boiling and stir until the sugar fully dissolves. Pour this hot vinegar mixture over the onions, letting them soak and develop their tangy flavor at room temperature while you prepare the rest of the taco components.

Step 2: Season the Salmon

Pat your salmon fillet dry, then sprinkle it evenly with chili powder, ground cumin, the remaining kosher salt, and half of the ground black pepper. These simple spices infuse the fish with a perfect balance of smoky warmth and subtle heat, readying it for a beautiful sear.

Step 3: Sear the Salmon

Heat vegetable oil in a large, oven-safe nonstick skillet over medium heat. Place the salmon flesh-side down and let it cook undisturbed for about 3 to 4 minutes. This step is crucial for developing a deep golden brown crust that locks in moisture and flavor.

Step 4: Finish Cooking the Salmon in the Oven

Flip the salmon so the skin side is down, then transfer the skillet to a 400 degrees Fahrenheit oven. Cook until the internal temperature reaches 145 degrees, which might take anywhere between 5 and 15 minutes depending on thickness. The result is a tender, flaky fish that stays juicy and flavorful.

Step 5: Prepare the Cabbage Mixture

While the salmon cooks, toss green cabbage, chopped cilantro, half of your Fish Taco Sauce, and the remaining ground black pepper in a large bowl. This crunchy, herbaceous blend adds refreshing texture and a burst of flavor that complements the salmon perfectly.

Step 6: Drain the Pickled Onions

Once your onions have marinated sufficiently, drain off the pickling liquid to avoid sogginess, leaving just the bright, piquant slices that will provide a lively punch to your tacos.

Step 7: Assemble the Tacos

After removing the salmon from the oven, run a spatula between the skin and flesh to discard the skin. Break the salmon into large, inviting chunks and arrange them atop warmed corn tortillas. Layer on the cabbage mixture, sprinkle with the pickled onions, and finish with creamy slices of avocado. Serve with the remaining Fish Taco Sauce on the side for drizzling as you please.

These salmon tacos pair wonderfully with light and fresh sides such as Mexican street corn, a simple black bean salad, or a zesty guacamole. The goal is to balance richness with refreshing, crisp flavors to round out your meal perfectly.

Make Ahead and Storage

Storing Leftovers

If you have any leftovers, keep the cooked salmon chunks separate from the cabbage mixture and pickled onions for best texture retention. Store everything in airtight containers in the refrigerator and consume within 2 days for maximum freshness.

Freezing

While the salmon can be frozen ahead of time, it’s best to freeze it plain, without assembling the tacos. Thaw it gently in the refrigerator before reheating. Avoid freezing the pickled onions or cabbage mixture, as their textures suffer from freezing.

Reheating

Reheat the salmon gently in a skillet over low heat or in a warm oven to prevent drying it out. Warm your tortillas separately to keep them soft and pliable. Reassemble the tacos just before serving to enjoy that lively contrast of flavors and textures.

FAQs

Can I use a different type of fish in this Salmon Taco with Cabbage, Pickled Onions, and Avocado Recipe?

Absolutely! While salmon offers a rich, buttery flavor, you can substitute with other firm fish like cod, halibut, or mahi-mahi. Just adjust cooking times accordingly to ensure the fish stays moist and flaky.

How long can I marinate the onions for the pickling part?

The quick pickled onions can sit for as little as 20 minutes to develop their tangy flavor, but leaving them at room temperature for up to an hour improves their zest and crunch. For a milder taste, refrigerate them after pickling.

What if I don’t have Fish Taco Sauce? Can I make my own?

Definitely, a simple sauce made from mayonnaise, lime juice, garlic, and a touch of hot sauce can work beautifully. It adds creamy tang and a little spice to complement the salmon and fresh veggies.

Can I prepare the cabbage mixture ahead of time?

Yes, you can toss the cabbage, cilantro, and sauce up to a few hours ahead and keep it chilled. This actually allows the flavors to meld nicely, but avoid mixing it more than a day in advance to keep the cabbage crisp.

Are these tacos gluten-free?

When made with corn tortillas, this Salmon Taco with Cabbage, Pickled Onions, and Avocado Recipe is naturally gluten-free. Just check your Fish Taco Sauce ingredients to confirm any pre-made sauces you might use.
