Blackened Grouper and Mango Salsa Ingredients

Use fresh or frozen Grouper filets. Fresh chopped pineapple will have a better flavor than canned, but both are fine.

For the Blackened Grouper

• Grouper filets - Fresh or frozen, about 24 oz for four servings.
• Blackening Seasoning - Any store bought or make our Blackening Seasoning Recipe.
• Olive oil - You will need one or two tablespoons of olive oil, or any vegetable oil.

For the Mango Salsa

• Mangoes - Large mango, or two of the small mangoes. Remove the seed, score the flesh, and flip each mango half out so you can cut the scored dice off the peel.
• Avocado - Large, seeded and peeled, then dice.
• Red Onion - About ¼ of a large red onion, or ½ of a small red onion, diced.
• Jalapeno - Seeded and diced. Optional, you can substitute a mild green or red bell pepper as well.
• Garlic - Fresh cloves, minced fine.
• Cilantro - Fresh chopped. Optional, if you omit, replace with green or red bell pepper for color.
• Lime juice - Fresh squeezed, about two medium limes.

How To Make Blackened Grouper

Cooking grouper filets in a hot cast iron skillet, or any skillet, takes only 2 - 3 minutes per side, so you'll want to prepare the mango salsa first so it can marinate.

I like to coat my fish filets with the blackening seasoning right after setting the mango salsa in the refrigerator to chill.

This lets more of the blackening flavors seep into the fish before searing them in the hot skillet. More flavor, win win!

Make The Mango Salsa First

1. In a large bowl, combine the diced mango, avocado, red onion, jalapeno, garlic, and fresh cilantro.
2. Add the fresh lime juice and season with salt and black pepper. Toss to combine and refrigerate to chill while preparing the blackened grouper filets.

PRO TIP: Prepare the Mango Salsa the day before, or morning of when you plan to blacken the grouper filets. The salsa will have time to marinate and blend the flavors together.

Prepare The Grouper Filets

1. Rinse the grouper filets and pat them dry with paper towels. This patting dry will help more of the blackening seasoning stick to the raw grouper filets.

Coat Both Sides With Blackening Seasoning

3. Sprinkle the blackening seasoning evenly over each side of the grouper filets. Rub in gently to ensure the seasoning is evenly distributed and adheres to the grouper filets.

Grouper Filets In Cast Iron Skillet

4. Heat 1-2 tablespoon of olive oil in a cast iron skillet over medium heat until hot.
5. Place the seasoned grouper filets into the hot skillet and cook 2 - 3 minutes on each side. Cook time will depend on the thickness of the filets.
6. Remove blackened grouper filets from the heat and transfer to a serving platter. Garnish with the chilled mango salsa on top, and serve immediately.

PRO TIP: If you have a Blackstone griddle, you can blacken about 16 fish filets at the same time, perfect if you are feeding a crowd! It's a great Blackstone alternative to steak!

Equipment

Storage and Reheating

• The cooked fish can be stored in the refrigerator for up to 3 days. The mango salsa can be stored in the refrigerator for up to 2 days.
• To reheat in the oven, preheat the oven to 350 degrees Fahrenheit. Place the dish in the oven and heat for 15-20 minutes, or until heated through.

Tips for Success

• Make sure to pat the grouper dry before cooking. This will help the spices to adhere to the fish.
• Cook the grouper over medium-high heat. This will help to ensure that the fish cooks evenly and does not become overcooked.
• Use fresh, ripe mangoes for the salsa.
• If using a Blackstone to cook the blackened filets, heat it to medium high, and oil it so the fish don't stick. Flip blackened filets after 2-3 minutes.
