Turmeric-Coriander Fish Tacos with Pickled Red Onion
Turmeric-Coriander Fish Tacos with Pickled Red Onion
Flaky seared fish gets a golden crust of turmeric and coriander, then tucks into warm tortillas with crisp lime slaw and sweet-tangy pickled onions. Thirty minutes, one skillet, big flavor.
What You'll Need
Any firm white fish works here — cod, tilapia, and mahi are all forgiving choices for a quick weeknight sear.
The Turmeric-Coriander Rub
- 1 tbsp Organic Turmeric Powder
- 1 tbsp Organic Coriander Powder
- 1 tsp Organic Red Chili Powder
- 1 tsp Organic Garlic Granules (swap in for a milder, sweeter edge)
- 1 tsp Fine Ground Himalayan Pink Salt
- 1.5 lbs firm white fish fillets
- 2 tbsp neutral oil
Pickled Onion & Slaw
- 1 small red onion, thinly sliced
- 1/2 cup white vinegar
- 1/2 cup water
- 1 tbsp sugar
- 1 tsp Organic Allspice Berries
- 2 cups shredded green cabbage
- 1/4 cup chopped cilantro
- 2 tbsp lime juice
- 1/4 tsp Organic Black Peppercorns, freshly ground
- 8 small corn or flour tortillas
- Lime wedges, for serving
Step by Step
Pickle the onions first
Combine vinegar, water, sugar, and allspice berries in a small saucepan. Bring to a simmer, drop in the sliced red onion, then remove from heat. Let it cool on the counter while you prep everything else — 15 minutes is enough to soften the bite and turn the onions a lovely pink.
Mix the spice rub
In a small bowl, stir together the turmeric powder, coriander powder, red chili powder, garlic granules, and salt until evenly blended. This rub does double duty as flavor and a beautiful golden crust on the fish.
Season the fish
Pat the fillets dry with paper towels — this helps the rub stick and the fish sear rather than steam. Coat both sides evenly, pressing gently so the spices adhere.
Sear until golden
Heat oil in a skillet over medium-high until shimmering. Add the fish and cook 3-4 minutes per side, undisturbed, until a deep golden crust forms and the fish reaches 145°F and flakes easily with a fork. Break into large chunks with a spatula.
Toss the slaw
In a bowl, combine shredded cabbage, cilantro, lime juice, and a pinch of freshly ground black pepper. Toss well and taste — add more lime if it needs brightness.
Warm the tortillas
Warm tortillas in a dry skillet or over an open flame for about 20 seconds per side, just until pliable and lightly toasted at the edges.
Build the tacos
Layer slaw, a generous portion of seared fish, and a few drained pickled onion rings into each tortilla. Finish with extra cilantro and a squeeze of lime.
Make the pickled onions the night before — they only get better sitting in the fridge, and you'll have a jarful ready for tacos, sandwiches, or grain bowls all week.
The Spices Behind the Tacos
Common Questions
Can I use frozen fish?
Yes — thaw completely and pat very dry before applying the rub so the spices form a proper crust instead of sliding off.
What if I don't have allspice berries?
You can pickle the onions plain, or swap in a few whole peppercorns and a pinch of cinnamon for a similar warm, spiced backdrop.
How spicy is this recipe?
It's mild by design, with just a teaspoon of chili powder. Add extra chili powder or hot sauce at the table for more heat.
Can I grill the fish instead of searing it?
Absolutely — brush the grates with oil, grill fillets over medium-high heat about 3-4 minutes per side, and flake as directed.
How long do the pickled onions keep?
Stored in their brine in a sealed jar in the fridge, they stay bright and crunchy for about two weeks.
