Easy Blackstone Fish Tacos

Blackstone Fish Tacos are an easy way to bring fresh flavor to your table. The combo of golden-seared tilapia, crisp toppings, and creamy sauce tucked in warm tortillas creates a crowd-pleasing meal that always disappears fast around here. Whenever I fire up the Blackstone, these tacos are the first thing my family requests.

I first tried this on a busy Tuesday when I wanted something new but fast. The griddle made the fish caramelized on the outside but soft inside and my friends raved for days.

Step-by-Step Instructions

Prepare and Preheat the Grill:

Set the Blackstone grill to medium high about 400 degrees F to ensure even searing and easy flipping later

Season the Fish:

Drizzle the tilapia filets with avocado oil and fresh lime juice then sprinkle both sides generously with chili powder garlic powder and salt pressing lightly so seasonings adhere well

Oil the Griddle:

Pour a small amount of oil onto the grill and spread evenly using a spatula to prevent sticking and help with that golden crust

Cook the Fish:

Lay the tilapia filets onto one side of the hot grill cooking undisturbed for 3 to 4 minutes on the first side until you see browning then flip gently with a spatula and cook the second side for another 3 to 4 minutes until the fish is opaque and flakes easily

Rest and Slice:

Transfer cooked fish to a clean plate and let it rest for 5 minutes so juices redistribute then slice into large chunks to keep them moist in the tacos

Mix the Sauce:

Combine sour cream lime juice mayonnaise garlic powder and sriracha in a small bowl stirring until completely smooth

Fry the Tortillas:

Melt butter on the empty side of the grill then lay out the mini tortillas directly in the butter flipping after a minute so both sides are lightly browned and flexible with crisped edges

Assemble:

Layer two warm tortillas per taco add generous pieces of the cooked tilapia then drizzle with a spoonful of sauce and pile on the cabbage avocado tomato onion cilantro and cotija cheese finish each with a squeeze of fresh lime

Serve:

Enjoy immediately while everything is hot and the tortillas are at their crispiest

Save

Cotija cheese is my personal favorite part its salty crumbly bite makes every taco extra special. I remember my sister and I racing for the last handful to sprinkle on top of our tacos laughter and cheese everywhere.

Storage Tips

Store leftover fish separately in an airtight container in the refrigerator for up to three days. Keep toppings like cabbage and tomato in small containers as well to keep everything crisp. Reheat fish gently in a pan over low heat or on the Blackstone to avoid drying out.

Ingredient Substitutions

Try cod or flounder if you do not have tilapia. Use Greek yogurt in place of sour cream for a lighter sauce. If you prefer flour tortillas swap them in but toast them on the griddle for best texture.

Serving Suggestions

Pair these tacos with a simple side of Mexican street corn or a crunchy slaw. They also go well with black beans and rice for a more filling meal. I love setting out extra lime wedges and pickled jalapeño for guests to customize to their liking.

Cultural Notes

While fish tacos have roots in the beach food buzz of Baja California they have become a mainstay of American cookouts and weeknight meals. The Blackstone method gives you that street taco vibe right at home and the smoky flavor feels like summer at any time of year.
