The magic here is texture — tender fish flakes against the crackle of jicama and cabbage — and balance: fresh mango sweetness, citrus acidity, and a savory kiss from the chili‑lime spice. This version is intentionally low in fat but not in flavor, trading heavy creams for the lift of lime and the creaminess of strained yogurt so the fish and produce remain the stars. It’s a practical recipe for summer cookouts and busy weeknights alike: the slaw can be made ahead (keep the dressing separate if you want maximum crunch), and the fish adapts cleanly to either the grill or an air fryer. Small technique choices — patting the fish dry, a very short marinade, warming tortillas so they don’t crack — make the difference between a good taco and one you’ll want to repeat. Serve these to guests who want bold fresh flavors with fewer calories, families who need a fast crowd‑pleaser, or anyone who appreciates clean, bright seafood. ## Recipe Information - Prep Time: 25 minutes - Cook Time: 12 minutes - Total Time: 37 minutes - Servings: 4 - Difficulty: Easy - Category: Mexican ## Ingredients ### Make a low‑fat lime marinade and marinate the fish - 1 1/2 lb Firm white fish fillets (mahi mahi, cod, halibut), skin removed if desired - 4 tbsp Fresh lime juice (divided: marinade, slaw, crema) - 1 tbsp Olive oil (or a neutral spray for lower fat) - 2 tsp Chili-lime spice blend (chili powder, ground cumin, salt, pepper) or store-bought ### Prepare the mango–jicama slaw - 1 large Ripe mango, peeled and diced - 1 cup Jicama, peeled and cut into matchsticks - 2 cups Shredded green cabbage - 1/4 cup Red onion, finely chopped ### Whip up the tangy yogurt–lime crema - 1/2 cup Low-fat plain Greek yogurt (for crema) ### Cook the fish — grill or air fryer - 8 count Small corn tortillas ## Ingredient Guide ### Jicama, peeled and cut into matchsticks Jicama is a crisp, slightly sweet tuber native to Mexico and commonly used in Mexican and Southeast Asian salads and slaws. Raw, it has a juicy crunch similar to water chestnut with a mild, slightly nutty flavor and little aroma. You can find it in the produce section of larger supermarkets or Hispanic/Latin markets; if unavailable, substitute raw water chestnuts, peeled apple or firm pear, or thinly sliced daikon for a similar crunch and mild sweetness. ## Instructions ### 1. Make a low‑fat lime marinade and marinate the fish Whisk 2 tbsp of the lime juice with the olive oil and the chili-lime spice blend; season lightly with salt and pepper. Pat the fish dry, place in a shallow dish or zip-top bag, pour the marinade over the fillets, and refrigerate for 15–30 minutes (no longer, or acid will begin to firm the fish). Remove fish from marinade and pat lightly with a paper towel before cooking. ### 2. Prepare the mango–jicama slaw In a large bowl, combine the diced mango, jicama matchsticks, shredded cabbage, and chopped red onion. Add 1 tbsp of the reserved lime juice, a pinch of salt, and toss gently to combine. For make-ahead: refrigerate the slaw in an airtight container up to 24 hours; if you prefer extra crunch, keep the lime tossed separately and add just before serving. ### 3. Whip up the tangy yogurt–lime crema Stir the low-fat Greek yogurt with the remaining 1 tbsp lime juice and a pinch of chili-lime spice or black pepper to taste until smooth; add 1–2 tsp of water if you want a thinner drizzle. Chill until assembly; the crema brightens the tacos with minimal fat compared with sour cream. ### 4. Preheat grill or air fryer and prepare for cooking If grilling: preheat to medium-high (about 400–450°F / 200–230°C) and clean and oil the grates. If using an air fryer: preheat to 400°F (200°C). Lightly brush the fish with a tiny extra swipe of oil or use cooking spray to prevent sticking; you want flavor without excess fat. ### 5. Cook the fish — grill or air fryer Grill fillets 3–4 minutes per side (depending on thickness) until opaque and flaky and an instant-read thermometer registers 145°F (63°C); avoid overcooking. For air fryer: place fillets in a single layer in the basket and cook 8–10 minutes at 400°F, flipping once halfway, until cooked through. Let fish rest 2 minutes, then flake into large pieces with a fork. ### 6. Warm tortillas and assemble tacos Warm tortillas on the grill or in a dry skillet for 20–30 seconds per side (or microwave wrapped in a damp towel for 20–30 seconds). To assemble: place fish pieces on each tortilla, top with generous mango–jicama slaw, and drizzle with the yogurt–lime crema; garnish with extra lime wedges if desired. Serve hot — recipe yields 8 tacos (about 2 tacos per person); serving size listed as 1 taco. ## Nutrition Estimated nutrition per serving (1 taco): - Calories: 507 kcal - Protein: 53.7 g - Carbohydrates: 42.2 g - Fat: 15.5 g - Saturated Fat: 2.6 g - Trans Fat: 0 g - Fiber: 7.1 g - Sugar: 12.2 g - Added Sugars: 0 g - Cholesterol: 121 mg - Sodium: 903 mg - Potassium: 1043 mg - Calcium: 156 mg - Iron: 5.4 mg - Vitamin D: 0 mcg ## Tips ### Keep the marinade short Because lime begins to cook fish on contact, limit marinating to 15–30 minutes to avoid a rubbery texture and to preserve delicate flavor. ### Dry the fish thoroughly Pat fillets completely dry after removing them from the marinade so the surface sears instead of steaming, which gives better color and prevents sticking. ### Air‑fryer spacing matters Arrange fillets in a single layer with space between pieces so hot air circulates evenly; cook in batches if needed to avoid a soggy exterior. ### Toss slaw before serving If making ahead, mix the lime with the slaw just before serving to keep jicama and cabbage crisp instead of limp. ### Warm tortillas the right way Heat tortillas briefly on a hot grill or skillet or wrap in a damp towel for 20–30 seconds in the microwave to make them pliable and prevent tearing. ## Variations and Substitutions ### Spicy chipotle shrimp Swap 1.5 lb peeled shrimp for fish and cut the chili‑lime blend with 1 tsp chipotle powder; shrimp will cook in 2–3 minutes per side on the grill. ### Dairy‑free crema Use unsweetened coconut yogurt or a cashew crema thinned with lime juice for a dairy‑free option that still offers tang and body. ### Blackened seasoning twist Replace the chili‑lime spice with a blackening rub and sear the fish hard for a smokier, more robust taco suited to bolder palates. ### Veggie‑forward tofu tacos Press and cube extra‑firm tofu, toss with the marinade, and air‑fry until golden for a vegetarian version with similar textures. ## Notes This is a lighter take on classic Baja tacos — bright, crunchy, and easy to scale for a crowd. The mango–jicama slaw can be made ahead, and the fish cooks quickly on the grill or in an air fryer for a fuss-free summer main. ### Storage and Make-Ahead Store components separately: keep slaw in an airtight container up to 24 hours (lime tossed separately if you want extra crunch) and the crema refrigerated up to 3 days. Cooked fish is best the same day but will keep tightly wrapped in the fridge for up to 24 hours; reheat gently in a 275°F oven covered with foil for 10–12 minutes to avoid drying. Assembled tacos do not store well and will become soggy, so assemble just before serving. ### Serving Suggestions Pair these tacos with grilled street corn (elote) or a chilled black‑bean and corn salad to echo the bright, citrusy flavors. For drinks, serve a light Mexican lager, a lime margarita, or a cucumber‑lime agua fresca; garnish tacos with extra lime wedges, chopped cilantro, and thinly sliced jalapeño for heat. ## Frequently Asked Questions ### Can I use frozen fish for this recipe? Yes — thaw frozen fillets fully in the refrigerator and pat dry before marinating; because thawed fish releases more moisture, shorten the marinade to the lower end of the 15–30 minute window. ### How do I prevent tortillas from falling apart? Warm tortillas until pliable and keep them wrapped in a clean kitchen towel; using small double‑layered corn tortillas or lightly toasting the edges helps them hold fillings without tearing. ### What’s the best way to tell when the fish is done? An instant‑read thermometer should register 145°F (63°C) in the thickest part, and the flesh will flake easily but remain moist; remove from heat promptly and let rest for 1–2 minutes. ### Can I make the slaw completely ahead of time? You can prep the slaw up to 24 hours in advance, but for maximum crunch keep the lime juice and any salt separate and toss them in just before serving. ### How can I add more heat without overwhelming other flavors? Thinly sliced fresh jalapeño or a drizzle of adobo sauce provides controlled heat; add sparingly so the mango sweetness and yogurt crema remain balanced. ## Related Recipes and Guides - [Cheesy Enchilada Casserole](https://www.topshelf.recipes/recipes/cheesy-enchilada-casserole) - [Instant Pot Beef Enchiladas](https://www.topshelf.recipes/recipes/instant-pot-beef-enchiladas) - [Smoked Pulled Pork Enchiladas](https://www.topshelf.recipes/recipes/smoked-pulled-pork-enchiladas-mole-pellet-smoker) - [Vegan Black Bean Enchiladas](https://www.topshelf.recipes/recipes/vegan-black-bean-sweet-potato-enchiladas) - [Chicken Enchiladas Red Sauce](https://www.topshelf.recipes/recipes/chicken-enchiladas-red-sauce) - [Green Chile Chicken Enchiladas](https://www.topshelf.recipes/recipes/green-chile-chicken-enchiladas) - [Weeknight Grill Roundup: 18 Recipes Under 30](https://www.topshelf.recipes/articles/weeknight-grill-roundup-18-under-30) - [Gluten-Free Weeknight Grilling Plan](https://www.topshelf.recipes/articles/gluten-free-weeknight-grilling-plan) - [Low-Fat Grill Swaps for Big Flavor](https://www.topshelf.recipes/articles/low-fat-grill-swaps-big-flavor)
