Tips When Buying Grouper…

When buying grouper from your local fish market:

  • The grouper should have a pale, opaque color with no obvious stains in the filet.
  • Ask how fresh the fish is. And ask if you can sniff it.
  • The fish should smell “fresh” – like the sea, and not nasty-fishy.
  • Also, a grouper is a fish with bones, so it’s best to ask the fishmonger to remove all skins, spines, and bones.

Ingredients Needed:

Here is a quick overview of the ingredients you will need:

  • Grouper Fish: the grouper should be skinless and boneless filet or fillets.
  • Vinegar: We prefer apple cider vinegar for a tangy, sweet flavor.
  • Honey: Choose any honey in your pantry; it will work with this recipe.
  • Dijon Mustard: A grainy (stony ground) Dijon mustard is best for the optimal flavor with grouper.
  • Extra Virgin Olive Oil: Choose the best quality of extra virgin olive oil for the best flavor in the glaze.
  • Garlic: You will need a few cloves of garlic, preferably minced.
  • Seasonings: You will only need some sea salt, black pepper, and cayenne pepper.
  • Fresh Parsley: Choose fresh parsley as the garnish on fish.
All the ingredients are displayed on the table, and a raw grouper is placed on wax paper.

How to prepare the Grouper?

Before you do anything to the grouper, give the fish a rinse under cold water, then allow it to drain and paper towel it dry. Now, your grouper is ready for any recipe.

Directions to Make It:

  1. Preheat the Oven: Preheat your oven to 350F degrees (180C).
  2. Prep the Grouper: Rinse and drain the grouper, and paper towel dry. Then transfer the fish to your baking dish.
  3. Make the Honey Mustard Glaze: In a small mason jar, measure all the ingredients and add them directly into the jar. Close and shake it until well combined.

  1. Pour and Bake: Pour enough glaze to cover the grouper, about 1/2 of the amount. Then place it on the middle rack of your oven and bake for 25 to 30 minutes, or until the internal temperature reaches 142F to 145F degrees.
  2. Before Serving: Transfer cooked fish to your plates and drizzle additional honey mustard glaze on top, garnish with minced parsley, and serve immediately.

This is a wonderful recipe to make with other kinds of fish as well. Try it with salmon, cod, halibut, and sea bass.


  1. What kind of fish is a Grouper? Grouper fish is one of the largest fishes found on coral reefs, and eat a wide range of marine life, including fish, crustaceans, and even small sharks.
  2. What does Grouper taste like? Grouper is a white fish with a mild flavor, similar to seabass and halibut. It has a light, sweet taste with large, chunky flakes, almost like lobster or crab.
  3. Why is Grouper an expensive fish? Some say grouper has a sweet flavor and flaky texture, Grouper is among the fish for “people who don’t like fish.” It is also a highly sought-after species, and most difficult to harvest.


Any “cooked” white fish should be stored in an air-tight container and kept chilled in the refrigerator. It will stay fresh for up to 2 days. After that, you should discard any leftovers.

Honey Mustard Grouper is an easy recipe for white fish baked with a flavorful honey mustard glaze. This grouper always turns out moist, tender, and delicious-tasting every time.

Prep Time 5 minutes
Cook Time 25 minutes
Total Time 30 minutes


  • 14 ounces skinless, boneless Grouper


  • 1/4 cup apple cider vinegar
  • 4 Tbsp. honey
  • 5 Tbsp. grainy Dijon mustard
  • 1/4 cup extra virgin olive oil
  • 1 tsp. minced garlic (about 2 cloves)
  • dash of cayenne pepper
  • 1/2 tsp. sea salt
  • fresh cracked black pepper, to taste
  • freshly minced parsley, as garnish


  1. Preheat the oven to 350 degrees F, (180C).
  2. In a small mason jar, measure all the ingredients for the Honey Mustard Glaze. Close the jar and shake it until well combined.
  3. Rinse and drain your grouper. Then use a paper towel to pat it dry. Place the grouper in your 2.5 Qt. (2.3L) round or oval baking dish.
  4. Pour about 1/3 cup of the honey mustard glaze over the grouper and let it sit to marinade until the oven has reached its temperature. When the oven is ready, place the grouper onto the middle rack in the oven.
  5. Bake for 25 to 30 minutes, until the fish flakes off when touched with a fork. Or when it reaches the internal temperature of 142F -145F degrees at the thickest part. Transfer to serving plates, and spoon some of that remaining glaze over the fish. Then add 1 to 2 tablespoons of the glaze from the baking pan or the jar over the fish. Garnish with freshly minced parsley and serve.


Important Notes To Remember:

  • Grouper will shrink in size when it is baked.
  • Plus, all ovens vary, so its best to check on the fish to see if its done, at 20 minutes.
  • And, this grouper can be served as 1 or 2 servings, if cut in half.
