Ingredients
- For the fish:
- 1.25–1.5 lb firm white fish fillets (cod, mahi-mahi, halibut, or tilapia)
- 2 tbsp avocado oil (or olive oil)
- 1.5 tsp chili powder
- 1 tsp smoked paprika
- 1 tsp ground cumin
- 1/2 tsp garlic powder
- 1/2 tsp onion powder
- 1/2 tsp sea salt
- 1/4 tsp black pepper
- Pinch of cayenne (optional, for heat)
- 1 lime, zested and juiced (divided)
- For the bowl base:
- 1 medium head cauliflower, riced (about 4 cups)
- 1 tbsp avocado oil or butter
- 1/2 tsp sea salt
- 1/4 tsp garlic powder
- Fresh toppings:
- 1 cup shredded green or purple cabbage
- 1 small avocado, sliced or cubed
- 1/4 cup red onion, finely diced
- 1/4 cup fresh cilantro, chopped
- 1 jalapeño, thinly sliced (optional)
- Lime wedges, for serving
- Creamy lime-cilantro sauce:
- 1/2 cup sour cream (or full-fat Greek yogurt)
- 2 tbsp mayonnaise
- 2 tbsp fresh lime juice
- 2 tbsp cilantro, finely chopped
- 1 small garlic clove, grated
- Pinch of salt
Cooking Instructions
- Season the fish: Pat fillets dry. Mix chili powder, smoked paprika, cumin, garlic powder, onion powder, salt, pepper, and cayenne.
Rub with avocado oil and spice mix. Add half the lime zest and 1 tsp lime juice. Rest 10 minutes.
- Make the sauce: Whisk sour cream, mayo, lime juice, cilantro, grated garlic, and a pinch of salt until smooth.
Adjust acid/salt to taste. Chill until serving.
- Cook the cauliflower rice: Heat 1 tbsp oil in a large skillet over medium-high. Add cauliflower rice, salt, and garlic powder.
Sauté 5–6 minutes until tender with a little bite. Remove from heat and set aside.
- Cook the fish (stovetop): Heat 1–2 tbsp oil in a nonstick or cast-iron skillet over medium-high. Add fish and cook 2–4 minutes per side depending on thickness, until it flakes easily and is opaque.
Squeeze with remaining lime juice.
- Alternative—bake or air-fry: Bake at 400°F (205°C) for 10–12 minutes or air-fry at 390°F (200°C) for 7–9 minutes, flipping once. Internal temp should reach about 135–140°F before resting.
- Flake the fish: Transfer to a plate and gently flake into big chunks. Don’t shred it into oblivion—you want texture.
- Assemble the bowls: Divide cauliflower rice between bowls.
Top with cabbage, avocado, red onion, jalapeño, cilantro, and generous chunks of fish. Drizzle with creamy lime-cilantro sauce. Finish with lime wedges and remaining lime zest for pop.
How to Store
- Fish: Store cooked fish in an airtight container for up to 3 days.
Reheat gently in a skillet over low heat or in the air fryer for 2–3 minutes to avoid drying out.
- Cauliflower rice: Keeps 3–4 days. Reheat in a skillet to revive texture.
- Sauce: Lasts 4–5 days in the fridge. Sauce tends to thicken; thin with a splash of lime juice if needed.
- Toppings: Keep cabbage, onions, and cilantro in separate containers to preserve crunch.
Slice avocado fresh (IMO, it browns fast even with lemon).
- Meal prep tip: Pack components separately and assemble right before eating for best texture.
Benefits of This Recipe
- Keto-aligned macros: High in protein and healthy fats, low in net carbs. The cauliflower rice keeps things light yet filling.
- Omega-3s (if using fatty fish): Mahi-mahi is lean, but salmon is an option if you want extra omega-3s and satiety.
- Micronutrient-dense: Cabbage, cilantro, and lime deliver vitamin C and antioxidants; avocado brings potassium and fiber.
- Anti-boredom insurance: Spice blend and creamy sauce create a restaurant-level flavor profile. No “diet food” vibes here.
- Customizable heat and texture: Jalapeño for kick, crunchy cabbage, silky sauce—each bite hits different.
Common Mistakes to Avoid
- Overcooking the fish: Dry fish ruins everything.
Pull it when it just flakes; it’ll finish cooking off heat.
- Watery cauliflower rice: Don’t overcrowd the pan. High heat, quick sauté. If it steams, it sogs.
- Underseasoning: Keto recipes need bold flavor.
Taste and adjust salt, lime, and spice at each step.
- Using low-fat dairy in the sauce: It’ll be tangy but thin. Full-fat keeps you satisfied and keto-friendly.
- Skipping the zest: Lime zest = amplified citrus flavor without extra carbs. Small detail, big payoff.
Different Ways to Make This
- Blackened salmon bowls: Swap fish for salmon; use extra paprika and cayenne.
Killer with the same sauce.
- Grilled version: Grill fish on an oiled grate or basket for smoky char. Great for summer cookouts.
- Chipotle-lime variation: Add 1–2 tsp chipotle in adobo (minced) to the sauce for smoky heat.
- Tropical twist: Add a tablespoon of diced pickled jalapeños and a few cubes of fresh cucumber for crunch. Keep fruit minimal to stay keto.
- Extra crunch factor: Top with crushed pork rinds for a tortilla-chip vibe without the carbs.
FYI, surprisingly awesome.
- Dairy-free: Swap sour cream/mayo for full-fat coconut yogurt and avocado oil mayo. Flavor stays sharp.
FAQ
What kind of fish works best?
Firm, mild white fish like cod, mahi-mahi, halibut, or tilapia hold up well and take on spice beautifully. If you want richer flavor and more healthy fats, try salmon—just adjust cook time since it’s thicker.
Can I make this without cauliflower rice?
Absolutely.
Use shredded lettuce for a taco salad vibe, or try sautéed zucchini ribbons. If you’re low-carb (not strict keto), a small portion of black soybeans can be added for fiber.
How do I keep the fish from sticking to the pan?
Use a well-oiled nonstick or properly preheated cast-iron skillet. Let the fish develop a crust before flipping—if it resists, give it another 30–60 seconds.
Is the sauce necessary?
Technically no, practically yes.
The sauce brings acidity and creaminess that balance the spices and richness. It’s the “restaurant” element at home.
What’s the estimated carb count?
Depending on portions, you’re looking at roughly 7–10g net carbs per bowl, mostly from cauliflower and toppings. Exact macros vary with brands and amounts, so plug it into your tracker for precision.
Can I make this spicy?
Yes—add cayenne to the rub, use serrano instead of jalapeño, and spike the sauce with chipotle or hot sauce.
You’re in charge of the fire.
Can I use frozen fish?
Yes, just thaw completely and pat very dry before seasoning. Extra moisture = steaming and blandness, which we don’t invite to dinner.
How do I meal prep this for the week?
Cook fish and cauliflower rice, mix sauce, chop toppings (except avocado). Store separately.
Reheat rice and fish gently, then assemble with fresh avocado and sauce right before eating.
My Take
Keto Fish Taco Bowls are the kind of meal that makes “eating clean” feel almost suspiciously easy. The spice crust on the fish, the lime-zinged sauce, and the crunchy cabbage bring fast-casual energy to your kitchen without the drive-thru detour. It’s efficient, satisfying, and endlessly modifiable—aka the trifecta for weekday wins.
If you want a low-effort, high-reward dish that still feels like a treat, this is it.
