In a small bowl, add the ground cumin, onion powder, garlic powder, and salt. Stir to combine.
Pat the tilapia fillets with a paper towel on both sides to remove any excess moisture.
Season both sides of the fillets with the seasoning mixture.
Heat olive oil in a large nonstick skillet over medium-high heat. Lay the fish in the skillet and cook for 3-4 minutes per side until cooked through.
Transfer fish to a plate and flake it into big bite-sized pieces with a fork.
Serve in warm corn tortillas and top with chipotle lime sauce, sliced radishes, shredded lettuce or cabbage, chopped cilantro, and lime wedges.
For the sauce
Add all ingredients to a small blender and blend until smooth. Serve immediately or chill in the fridge until ready to eat.
Notes
To add a little extra crunch, serve each taco with shredded cabbage, lettuce, or a creamy topping like my Fish Taco Slaw or this easy jicama slaw.
Don't have tilapia? You can use cod, flounder, or sole instead.
To make the chipotle lime sauce spicy, add an extra chipotle pepper in adobo sauce. The yogurt really tames the heat of the pepper, so you may need to add more if you like it hot!
These tacos are great served in corn and flour tortillas! You can use your favorite store-bought tortillas or make your own using these corn tortilla or flour tortilla recipes.
