Prep the oven and pan. Heat oven to 450°F (232°C). Line a sheet pan with parchment and set a wire rack on top. Lightly oil the rack. This keeps the fish elevated and crisp on all sides.
Mix the dredge. In one shallow bowl, whisk the flour with salt, pepper, smoked paprika, garlic powder, and chili powder. In a second bowl, beat the eggs. In a third, pour the panko.
Portion the fish. Pat fish dry and cut into 1-inch-wide strips. Dry fish = better crunch. No soggy energy here.
Bread it right. Dredge fish in seasoned flour (shake excess), dip in egg, then coat in panko, pressing gently to adhere. Arrange on the rack and drizzle or mist lightly with oil.
Bake to golden. Bake 10–14 minutes, flipping once midway, until the coating is deep golden and the fish flakes easily. Internal temp should hit about 145°F (63°C). If you want extra color, broil for 60–90 seconds at the end. Watch closely.
Make the slaw. While fish bakes, toss cabbage, carrots, cilantro, green onion, and jalapeño with lime juice, vinegar, olive oil, honey, and salt. Taste and adjust acidity and salt. It should be punchy.
Whisk the crema. Combine yogurt, mayo, lime juice, zest, garlic, cumin, and salt until smooth. Thin with a splash of water if needed for drizzling.
Warm the tortillas. Wrap tortillas in foil and warm in the oven for 3–5 minutes, or toast individually in a dry skillet for 20–30 seconds per side.
Assemble. Tortilla, slaw, crispy fish, drizzle of lime crema, cilantro, maybe a squeeze of lime and a few radish slices. Repeat until happy.
Serve immediately. Crispy things wait for no one. Call the squad before you pull the pan.
