Traeger Blackened Fish Tacos
Traeger blackened fish tacos are a house favorite—simple, full of flavor, and ready in about 20–30 minutes from start to finish. The method is straightforward: a hot cast-iron pan on the grill, a liberal dusting of blackening seasoning, and minimal handling so the fish stays flaky and intact.
What’s in the slaw?
A quick slaw softens the cabbage and adds bright citrus notes. Use a pre-shredded coleslaw mix or finely sliced cabbage and toss with fresh lime juice to taste. For assembly, spread a thin layer of slaw on a warm corn tortilla, top with a piece of blackened fish and a spoonful of salsa or sauce, then finish with a squeeze of lime.
What kind of fish is best for grilled fish tacos?
Firmer, white-fleshed fish work best for blackened tacos because they hold together on the grill and take on a nice crust. Rockfish was used here, but bass, halibut, cod, flounder, and walleye are all excellent choices. Choose fresh filets that are roughly similar in thickness so they cook evenly.

What kind of sauce goes on fish tacos?
Fish tacos pair well with a range of toppings. A citrusy slaw provides crunch and brightness, but creamy sauces are also popular. Avocado-lime sauce is a classic accompaniment. For a tangy, creamy option, mix sour cream with lime juice and garlic; add a splash of hot sauce like Tapatío or Cholula if you want heat.
Can other types of fish pinch hit?
Yes. Most white fish handle the blackening process and grill heat well. Try cod, rockfish, walleye, halibut, or flounder. Adjust cooking time based on thickness—thinner filets will cook faster.
What is blackening?
Blackening is a cooking technique that creates a deeply colored, flavorful crust on fish or other proteins. Traditionally, filets are dipped in melted butter and dredged in a spice blend before cooking in a very hot pan. For a lighter version, you can skip the butter and use a very hot, well-seasoned cast iron pan with a light spray of avocado or other high-heat cooking oil to prevent sticking.
Blackening seasoning usually includes garlic powder, onion powder, thyme, oregano, black pepper, and chili pepper, among other spices. The combination caramelizes against the hot pan and forms a rich, dark crust without tasting burnt.
Where can I get blackening seasoning?
Pre-made blackening blends are widely available at spice shops and online retailers. If you prefer to make your own, a simple homemade blend of paprika, garlic powder, onion powder, thyme, oregano, cayenne, and black pepper works very well. Taste and adjust proportions to suit your heat preference.
Is blackened fish burnt?
No. Blackened fish has a dark, deeply seasoned crust created by spices and high heat. When done correctly it’s richly flavored rather than burnt. Avoid overheating the pan to the point of smoking and follow recommended cooking times to keep the interior moist and flaky.
Can you reheat these?
Fish is best fresh, but leftovers keep in the refrigerator for 2–3 days. Reheat gently: avoid the microwave, which dries fish out. Instead, warm filets in an oven set to 250°F (about 120°C) for roughly 10 minutes, or use an air fryer for a few minutes until heated through.
How to make grilled blackened fish tacos
Grilling blackened fish tacos is straightforward, but a few key techniques make a big difference:
You need a cast-iron pan
Use a cast-iron skillet or a grill-safe flat that prevents delicate filets from falling through the grates. A sturdy surface helps develop an even crust and keeps the fish intact.
Preheat your pan with the grill
Place the pan on the grill while it preheats so it becomes blistering hot. A thoroughly heated pan produces the best crust quickly, minimizing cooking time and preserving moisture.
Don’t skimp on the seasoning
Generously dust all sides of the fish with blackening seasoning for full flavor. The seasoning is what creates the characteristic dark, well-seasoned exterior.
Leave it alone
Once the fish is in the hot pan, avoid moving it. Let it form a crust and flip only once with a wide spatula to keep the filets intact. Frequent flipping increases the chance of breaking the fish apart.
Can I cook blackened fish tacos in the oven or on the stove?
Yes. On the stovetop, preheat the pan thoroughly and consider a light cover to help finish cooking. In the oven, use the same principle: a very hot pan and minimal handling. Grilling does add a subtle wood-fired flavor that many enjoy, but stovetop or oven methods work well when grilling isn’t an option.

Instructions
- Preheat your Traeger or grill to 400°F (204°C). Place a cast-iron pan on the grill while it preheats so the pan becomes very hot.
- Generously dust all sides of the fish with blackening seasoning.
- Carefully remove the hot pan using a pot holder, and spray lightly with cooking spray off the grill. (Do not spray while the pan is on the grill; spray is flammable.)
- Return the pan to the grill, place the fish in the pan, and close the lid.
- Grill for 4–5 minutes until the bottom is browned and a crust has formed.
- Flip the fish carefully one time with a wide spatula, close the lid, and cook an additional 4–5 minutes.
- Cooking time depends on filet thickness—thinner filets cook more quickly. The fish is done when it is no longer translucent and flakes easily with a fork.
