Ingredients for This Recipe
Roasting is a balanced way to cook sea bass because the flesh is evenly cooked through and the skin is crispy.
We season the fish with a diverse blend: Cajun seasoning, garlic powder, paprika, salt, and pepper are the spices that we use in this recipe, with garlic acting as an aromatic. Lastly, we add olive oil to combine everything.
Polenta plays the role of the starch component – which is usually rice, pasta, or mashed potatoes.
In this recipe, we make polenta by mixing cornmeal with chicken broth and milk. Water is more than enough to get the job done, but cooking polenta with broth and milk adds two things: extra flavor and creaminess.
To double down on the richness, we stir in parmesan cheese, butter, and heavy cream. This polenta makes a perfect “sauce” to eat with the fish.
Crunchy asparagus and lemon slices are roasted alongside the fish. These vegetables release flavors that blend with the fish, adding more taste to the sea bass fillets.
Sautéed mushrooms make a mini side dish that adds a different texture to the dish.
How to Make Sea Bass Skin Crispy in the Oven
The first step is to make sure that the skin is dry. Patting the fillets dry with paper towels and then letting them rest at room temperature for an hour will effectively dry the skin.
Placing the fish correctly will also help crisp the skin. Similar to searing on a hot pan, laying the fish skin-side towards the heat source will make it crispy. In this recipe, we roast the sea bass fillets skin-side up so that they are near the upper heat source.
How to Store and Reheat Leftovers
Sea bass will last for 3-4 days in the fridge and up to 4 months in the freezer. Store the leftovers in airtight containers or heavy-duty freezer bags.
You can reheat the fish the same way you cooked it. Place the fish on a lined baking tray or baking dish and cover with foil to lock in the moisture. Bake in a 275 °F preheated oven until the fish reaches 145 °F.
