Ingredients

Trout and Marinade

• 4 fresh Idaho Rainbow Trout fillets (boneless)
• 2 tbsp Olive oil (for brushing)
• 1 tsp Sea salt
• 1/2 tsp Freshly ground black pepper
• 1/2 tsp Garlic powder (optional)

Zesty Cabbage Slaw

• 2 cups Green cabbage, thinly shredded
• 1 cup Purple cabbage, thinly shredded
• 1/4 cup Fresh cilantro, chopped
• 1 Jalapeño, seeded and minced (optional for heat)
• 2 tbsp Lime juice (freshly squeezed)
• 1 tbsp Honey or agave syrup
• 1 pinch Salt and pepper to taste

Taco Assembly

• 8 Corn tortillas
• 1 large Avocado, sliced
• 1/4 cup Cotija cheese, crumbled
• Lime wedges (for serving)
• Favorite hot sauce

Instructions

Step 1: Prep and Preheat

1. Start by firing up your Arteflame grill. Aim to get the cooktop hot and ready for grilling. You want a medium-high heat zone for the fish.
2. While the grill heats, prepare the slaw. In a medium bowl, combine the shredded green and purple cabbage, cilantro, lime juice, honey, and minced jalapeño. Toss well to coat and season with salt and pepper. Set this aside to let the flavors marry.
3. Pat the trout fillets dry with a paper towel. This ensures a good sear. Brush both sides of the fish with olive oil and season generously with sea salt, pepper, and garlic powder.

Step 2: Grill the Trout and Tortillas

1. Apply a thin layer of oil to the flat cooktop surface of the Arteflame.
2. Place the trout fillets on the cooktop, skin-side down first (if the skin is on). Cook for about 2-3 minutes until the skin crisps up and releases easily from the metal.
3. Flip carefully and cook the flesh side for another 1-2 minutes. The fish is done when it is opaque and flakes easily with a fork. Move the fish to the outer, cooler edge of the grill to stay warm.
4. While the fish rests for a moment, place the corn tortillas directly on the hot griddle surface. Toast them for about 30-45 seconds per side until they are pliable and have slight char marks.

Step 3: Assemble and Serve

1. Remove the tortillas from the grill.
2. Flake the grilled trout into large chunks, discarding the skin if you prefer (though crispy skin adds texture).
3. Layer the fish onto the warm tortillas. Top generously with the zesty cabbage slaw and slices of fresh avocado.
4. Finish with a sprinkle of crumbled Cotija cheese and a drizzle of your favorite hot sauce. Serve immediately with extra lime wedges on the side.

Tips

Cooking delicate fish like rainbow trout requires a bit of finesse, especially when working with a flat-top grill. To get the best results, ensure your cooktop is well-seasoned with oil before placing the fillets down to prevent sticking. Aim for the medium-heat zones of the griddle rather than the searing center; trout cooks quickly, and you want to retain its moisture. If your fillets still have the skin on, always grill skin-side down first to get it nice and crispy—it adds a fantastic texture and helps hold the fish together. For the slaw, try to make it at least 20 minutes before serving. This allows the lime juice and salt to break down the cabbage slightly, resulting in a more tender crunch that integrates better with the soft fish. Finally, don’t skimp on the lime; the acidity cuts through the richness of the trout perfectly.

Variations

While Idaho Rainbow Trout is the star here, this recipe is incredibly flexible and can be adapted to suit whatever is fresh at the market or in your tackle box. If you cannot find trout, other white fish like tilapia, snapper, or mahi-mahi work beautifully on the flat top. For those who crave a bit more heat, try adding a dusting of cayenne pepper or smoked paprika to the fish before grilling. You can also swap the flavor profile entirely by using a mango salsa instead of the traditional cabbage slaw for a sweeter, tropical vibe. For a low-carb option, skip the tortillas entirely and use large butter lettuce leaves.

• Spicy Kick: Add chipotle powder to the fish rub.
• Tropical Twist: Top with mango or pineapple salsa.
• Low Carb: Use Butter Lettuce or Romaine leaves instead of tortillas.
• Creamy Style: Add a drizzle of chipotle lime crema.
• Shellfish Swap: Replace trout with grilled shrimp or scallops.

Best pairings

A light, flavorful meal like fish tacos calls for equally refreshing beverages and sides that won't overpower the delicate taste of the trout. A crisp, cold Mexican lager with a wedge of lime is the classic choice, cutting through the savory spices. Alternatively, a chilled Sauvignon Blanc or a dry Rosé pairs wonderfully with the citrus notes in the slaw. For non-alcoholic options, a sparkling cucumber limeade or an iced hibiscus tea is a crowd-pleaser. As for side dishes, consider utilizing the rest of your grill space while the fire is hot. Grilled corn on the cob (elote style) is a natural companion, as is a simple salad of grilled peppers and onions.

• Mexican Lager or Pale Ale
• Chilled Sauvignon Blanc
• Grilled Corn on the Cob (Elote)
• Black Bean and Corn Salad
• Cilantro Lime Rice
