Ingredients
Fresh and Simple Ingredients
To make this glazed fish recipe, you’ll need fresh mackerel fillets, Dijon mustard, honey, garlic, lemon juice, soy sauce, and a few spices. These ingredients come together to create a flavorful and aromatic dish that’s sure to impress.
Substitutions and Variations
If mackerel isn’t available, you can substitute with other firm white fish such as cod or haddock. For a spicy kick, add a pinch of cayenne pepper to the glaze. Experiment with different mustard varieties, like whole grain or spicy brown, to customize the flavor to your liking.
Step-by-Step Instructions
Preparing the Mackerel
Start by preheating your oven to 400°F. Rinse the mackerel fillets under cold water and pat them dry with paper towels. Season both sides with salt and pepper, then place them skin-side down on a baking sheet lined with parchment paper.
Creating the Mustard Glaze
In a small bowl, whisk together Dijon mustard, honey, minced garlic, lemon juice, soy sauce, and a dash of salt. Once combined, brush the glaze generously over the mackerel fillets, ensuring an even coating.
Baking to Perfection
Place the baking sheet in the preheated oven and bake the mackerel for 15-20 minutes, or until the fish is opaque and flakes easily with a fork. The glaze should be bubbling and slightly caramelized. For an extra golden finish, broil the fish for an additional 1-2 minutes.
