Recipe Ingredients

  • Grouper fillets: Fresh or frozen, if using frozen, thaw in the fridge overnight.
  • Blackened seasoning: When buying a blackened seasoning, try to find one that doesn’t have salt listed as the first ingredient.
  • Vegetable oil: Use whatever you have on hand; olive oil, canola, and grapeseed will all work well.
  • Lemon: Sliced or cut into wedges, to be served with the grouper.
  • Parsley: I like to use fresh parsley, but dried parsley will also work as a garnish.

Variations

  • Add more Spice: Sprinkle the fish with a touch of cayenne pepper or red chili flakes.
  • Swap the Fish: Instead of grouper, use your favorite white fish.
  • For a Change of Pace: Instead of eating with a few sides for dinner, stuff the fish into taco shells instead of your usual go-to fillings.

How To Make Pan Fried Grouper

Step 1: Dry the grouper fillets with paper towels and brush both sides with half the vegetable oil.

Tips for the Best Blackened Grouper

  • Dry Fish Will Hold the Oil Better: Make sure to pat the fish well so the oil sticks. Once the fish is coated in oil, it will hold the blackened seasoning well.
  • Preheat the Pan: If the pan is hot when the fish hits it, you’ll get a nice crispy coating.
  • Fresh Seasoning: You’ll get a way better tasting dinner if your blackened seasoning is fresh. If it’s been sitting in your pantry for more than a year, toss it and buy a new one.
  • Watch the Cook Time: Depending on the thickness of your fish, the cook time may vary. Fully cooked fish is opaque and flakes easily.

Grouper is a Good Source of Protein

Low in Fat and High in Protein: Grouper is a good source of lean protein, making it an excellent choice for those looking to maintain or increase muscle mass while lowering calorie intake. For example, 3oz of grouper is about 17 grams of lean protein. It’s also relatively low in saturated fat.

Vitamins and Minerals: Grouper provides various nutrients, including B vitamins (especially niacin and B6), phosphorus, potassium, and selenium. These play roles in energy production, bone health, immunity, and more.

Omega-3 Fatty Acids: While not as high in omega-3 fats as oily fish like salmon, grouper still contributes a moderate amount of these heart-healthy fats.
