Step-by-Step Cooking Instructions

Learning to cook blackened mahi mahi needs precision and the right technique. Start by preparing your ingredients and setting up the perfect cooking area. Pat your mahi mahi filets dry with paper towels for a crispy crust.
Make your blackening seasoning by mixing these spices:
- 1 teaspoon paprika
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- ½ teaspoon sea salt
- ¼ teaspoon dried thyme
- ¼ teaspoon ground black pepper
- ⅛ teaspoon cayenne pepper
Coat both sides of the mahi mahi with the spice mix. Heat a cast-iron skillet over medium-high heat and add olive oil. The cooking technique is key for a perfect blackened crust.
Place the seasoned filets in the hot skillet. Cook for 3-4 minutes on the first side until it’s dark and crispy. Flip the fish and cook for another 2-3 minutes. The fish should reach 145 degrees Fahrenheit for the best taste.
Pro tip: Avoid moving the fish while it cooks to develop a beautiful, crisp blackened crust.
Total cooking time is about 15 minutes, making two 6-ounce servings with 25 grams of protein.
Creating the Perfect Avocado Lime Sauce
Elevate your spicy blackened fish with a creamy avocado lime sauce. This sauce turns your meal into something special. It adds fresh flavor that matches the bold taste of your blackened mahi mahi.
Blending the Perfect Sauce Consistency
To make the perfect avocado lime sauce, focus on texture and technique. Use a food processor or blender for a smooth, creamy sauce. Choose a ripe avocado that’s slightly soft but not too mushy.
- Use a large ripe avocado (approximately 1 whole)
- Add ⅓ cup Mexican crema or sour cream
- Incorporate ⅓ cup finely chopped cilantro
- Squeeze in 2 tablespoons of fresh lime juice
Balancing Flavors and Heat Levels
For an amazing avocado lime sauce, balance the flavors well. Start with ½ teaspoon of salt and adjust to taste. Add finely chopped serrano peppers for extra heat.
Ingredient | Quantity | Flavor Impact |
---|---|---|
Lime Juice | 2 tablespoons | Brightness and Acidity |
Cilantro | ⅓ cup | Fresh Herbaceous Note |
Serrano Pepper | To taste | Heat Level Control |
Make-Ahead and Storage Tips
Your avocado lime sauce recipe can be made ahead of time. Store it in an airtight container in the fridge for 3-4 days. Press plastic wrap directly on the sauce to stop it from browning.

Use this creamy sauce on fish tacos or as a dip. It will make your dishes more vibrant and delicious.
Serving Suggestions and Pairings
Turn your blackened mahi mahi into versatile dishes with different serving options. Try blackened mahi mahi tacos for a fun twist on a healthy meal. They’re great for a quick dinner or a laid-back weekend meal.
Wrap the fish in soft tortillas, add fresh slaw, and drizzle with avocado lime sauce. This mix of flavors is exciting.
For a fancier look, serve the mahi mahi over coconut or cauliflower rice. These options are low in carbs and add a tropical flavor. Roasted potatoes or a fresh corn salad add texture and balance.
Grilled zucchini and bell peppers add a smoky taste that goes well with the blackened seasoning.
Try different side dishes to make your meal even better. A cucumber dill salad is fresh and herby, while a quinoa salad adds a nutty crunch. For bold flavors, mango salsa or pineapple chutney can add sweetness and tanginess.
Pair the fish with quick and easy sides to enhance your meal. Sautéed spinach balances the fish’s richness, and almond flour biscuits are tender and soak up juices. The key is to mix textures and flavors for a great meal.
