Fish Tacos (Light, 25g Protein)

2026-02-267 min read + cook time 15 min

[!TIP] Use corn tortillas

  • Corn tortillas = 50-70 cal each (smaller standard)
  • Flour tortillas = 100-150 cal each (much heavier)
  • Tacos feel indulgent with corn tortillas but keep calories reasonable

Why This Works

Fish taco advantages:

  • Fresh, light: Easier on stomach than heavier meats
  • High protein: 6 oz fish = 35g protein spread across tacos
  • Customizable: Add/subtract toppings for appetite/texture preferences
  • Different from standard fare: Keeps meals from getting boring

GLP-1 portion reality:

  • Restaurant: 3-4 tacos + side + chips = 1000+ cal
  • This recipe: 2-3 tacos = legitimate meal (350-450 cal)
  • Appetite naturally smaller = won't eat restaurant portions anyway

Fish Options

| Fish Type | Protein (6 oz) | Flavor | Best For | |-----------|---------------|--------|----------| | Cod/White fish | 25-30g | Mild | Classic, versatile | | Tilapia | 30g | Mild | Inexpensive, cooks fast | | Mahi-Mahi | 30g | Mild | Similar to cod, slightly firm | | Halibut | 35g | Mild | Higher protein, pricier | | Salmon | 35g | Rich | Strong flavor (not traditional, but good) | | Shrimp | 25g | Sweet | Already covered separately |

Recommendation:

  • Cod/Tilapia = inexpensive, mild, cooks fast
  • Halibut/Mahi-Mahi = if budget allows, slightly firmer
  • Salmon = if you like strong fish flavor (not traditional but works)

Base Recipe (Cod Fish Tacos)

Ingredients (makes 4-6 tacos):

Marinade/Seasoning:

  • 6 oz cod fillet (or tilapia/mahi-mahi)
  • 1 tbsp olive oil
  • 1 tbsp lime juice (fresh)
  • 1 tsp cumin
  • 1/2 tsp chili powder
  • 1/2 tsp garlic powder
  • Salt + pepper

Tacos:

  • 4-6 small corn tortillas (50-70 cal each)
  • 1/2 cup shredded cabbage or lettuce mix
  • 1/2 cup pico de gallo (salsa)
  • 2 tbsp fresh cilantro, chopped
  • Optional: 1/4 cup sour cream or Greek yogurt
  • Optional: 2 tbsp cotija cheese (crumbly white cheese, optional)

Directions:

  1. Marinade fish: Mix olive oil + lime juice + spices. Rub over fish (15 min marinade OK, longer is fine).
  2. Cook fish:
    • Pan-sear: Hot skillet with oil, 3-4 min per side.
    • Oven bake: 400°F for 8-12 min (for larger pieces).
    • Air fryer: 8-10 min at 375°F.
  3. Season fish: Additional salt + pepper if needed.
  4. Warm tortillas: Briefly warm in dry pan 30 sec per side (softens, not crunchy).
  5. Assemble tacos: Flake fish, distribute across tortillas, add cabbage, pico de gallo, cilantro.
  6. Add optional toppings: Sour cream/Greek yogurt + cotija cheese.
  7. Serve with lime wedges (fresh squeeze adds brightness).

Cooking Methods

Pan-Seared (Preferred)

Why it works:

  • Creates slight crust on fish
  • Fast cooking
  • Easy to watch doneness

Method:

  • Heat skillet medium-high, add 1 tsp oil.
  • Sear fish 3-4 min per side.
  • Done when fish flakes easily.

Oven-Baked

Why it works:

  • Hands-off
  • Good for larger pieces
  • Less oil needed

Method:

  • Preheat 400°F.
  • Place cod on baking sheet (lined with parchment).
  • Season as above with oil + spices.
  • Bake 8-12 min until translucent (cooking time varies by thickness).

Air Fryer (Fast)

Why it works:

  • Fast, consistent cooking
  • Less oil than pan-sear
  • Crisps slightly (fish doesn't fry, but nice effect)

Method:

  • Preheat 375°F.
  • Place cod in basket (may need 2 batches depending on size).
  • Cook 8-10 min, flip halfway.

Topping Variations

Classic Baja Style

  • Cabbage + pico de gallo + sour cream
  • Fresh cilantro, radish slices
  • Lime wedges

Spicy Arrabbiata

  • Add jalapeño slices + hot sauce
  • Omit sour cream (or use Greek yogurt mixed with hot sauce)
  • Extra chili powder in fish seasoning

Avocado Cream

  • Mash 1/2 avocado + 1 tbsp lime juice + 2 tbsp Greek yogurt
  • Use instead of sour cream (healthy fat substitute)
  • Adds creaminess without heavy calories

Mango Salsa

  • Replace pico de gallo with mango salsa (sweeter)
  • Still use cabbage crunch
  • Tropical spin on classic

Greek Yogurt "Sour Cream"

  • 2 tbsp Greek yogurt + 1 tsp lime juice + 1 tsp cumin
  • mimics sour cream, adds protein, fewer calories

Comparison:

  • Regular sour cream: 60 cal per 2 tbsp, 0g protein
  • Greek yogurt sub: 30 cal per 2 tbsp, 4g protein

Tortilla Options

| Tortilla Type | Calories | Protein | Flavor Profile | |---------------|----------|---------|----------------| | Corn tortilla (small) | 50-70 cal | 1-2g | Authentic, corn flavor | | Flour tortilla (small) | 100-150 cal | 2-3g | Softer, less corn taste | | Cauliflower tortilla | 30-60 cal | 0-1g | Low carb alternative | | Coconut tortilla | 30-50 cal | 0g | Grain-free option |

Recommendation:

  • Corn tortillas = authentic, low-cal
  • If intolerant: Cauliflower or coconut (more expensive option)
  • Avoid large flour tortillas (too calorie-dense for GLP-1 portions)

Side Options

As complete meal (with small side):

  • Guacamole: 1/2 avocado mashed = 120 cal + healthy fats
  • Black beans: 1/4 cup = 60 cal + fiber
  • Mexican rice: 1/4 cup = 50-70 cal (if you can handle starch)
  • Extra veggies: Cucumber, jicama, radish (minimal calories, crunch)

Avoid standard restaurant sides:

  • Chips and salsa: 400-500 cal for small portion
  • Fried side dishes: Add unnecessary calories
  • Heavy refried beans: Can be 200 cal for 1/2 cup

Meal Prep

Fish cooking:

  • Fish doesn't hold up well as leftovers (gets fishy).
  • Cook fresh day-of (best approach).
  • Or cook fish in morning, assemble tacos for dinner later.

Tortillas/toppings:

  • Tortillas hold for days.
  • Cabbage/lettuce: Prep ahead, store separately.
  • Pico de gallo: Fresh is best, but store-bought works.
  • Cilantro: Freshest same day

Reheating:

  • Fish: Reheating makes fish fishy - best cooked fresh
  • Tortillas: 30 sec microwave or toaster (warms, not crunchy)
  • Assembly: Assemble tacos right before eating

[!WARNING] Watch fish doneness

  • Undercooked fish: Still translucent, raw texture
  • Perfect: Flakes easily with fork, opaque throughout
  • Overcooked: Dry, tough, unpleasant (fish dries out fast)
  • Better undercooked than overcooked (for cod - firm white fish like halibut, aim for perfect)

[!NOTE] Cod vs Tilapia

  • Cod: Slightly firmer texture, tends to be higher quality
  • Tilapia: Often cheaper, softer texture
  • Both work fine in tacos
  • Freshness matters more than variety (off fish = bad tacos regardless)

[!BONUS] Fish is lean protein

  • 6 oz cod = 120-150 cal, 30g protein WITHOUT tortilla/toppings
  • Compare: 6 oz beef = 350-400 cal, 30g protein (much higher fat/calories)
  • Same protein, way fewer calories with fish
