What is Branzino Fish
Branzino is a European or Mediterranean Sea Bass. I'm a big fan of all types of sea bass and this one is definitely no exception!
Branzino has a mild and slightly sweet taste, similar to other types of sea bass and halibut. It is known for its lean white-firm meat and perfectly grilled, roasted, baked, steamed, or pan-seared.
The Best Substitutes for Branzino
If you can't find Branzino, feel free to substitute with flounder, Atlantic croaker, sea trout, red snapper, or any fish that is white, lean, and flaky.
Where to Purchase and Branzino Fish Price
You can purchase Branzino at Costco, Trader Joe, Whole Foods, or any seafood market. It's sold both as a whole fish and as fillets.
It's around $12.99 per pound (whole fish) or $7 per pound (fillets).
Ingredients for Pan-Seared Branzino
To make pan-seared branzino you will need branzino fillets, oil, lemon, butter, salt, black pepper, and fresh thyme leaves.
How to Pan-Sear Branzino Fillets
I usually cook fish fillets skin-side down first. However, for this particular recipe, in order to keep the skin crispy after basting, I decided to cook the skin side up first.
Basting will add flavor and keep the fish from drying out. The extra fat also helps crisp up the skin.
Step 1. Add Seasoning to Fish
- Pat the fish fillets dry with paper towels.
- With your hand at least 12 inches away, lightly sprinkle salt and black pepper on both sides of fish fillets in a single layer.
Step 2. Preheat Your Pan
- Preheat a heavy large non-stick or stainless-steel skillet over high heat for about 3 minutes (hot but not smoking).
- Reduce the heat to medium, add oil and wait a few seconds for the oil to heat.
Step. Pan-Sear
- Place the fish fillets in the hot pan, skin side up. Cook for about 90 seconds - 2 minutes or until lightly browned. Do not overcrowd the pan to prevent steaming. Work in multiple batches if needed.
- Carefully flip the fish fillets and cook the skin for about 3 minutes. Using a spatula, hold for a few seconds to ensure even cooking and crisp skin all over.
- Add butter, thyme, and fresh lemon juice to pan. Tilt the pan slightly and use a spoon to baste the fish with melted butter. Continue basting until cooked through for about 1 minute or more, depending on the thickness of the fish.
FAQ and Cooking Tips
Here's how to get the perfect crispy skin:
1. You have to dry the fish really well with paper towels. After that, place the fish fillets on a wire rack and let them come to room temperature on the counter for 15 minutes before you cook them.
2. Do not overcrowd the pan to prevent steaming. The more food added, the lower the temperature falls. Make sure that the fish fillets have plenty of space and are not touching each other.
3. Always preheat the skillet for a few minutes.
4. Don't salt your fish until right before you put it in the pan because salt draws moisture to the surface of the fish.
Place the leftover cooked fish in an airtight container. If the fish is still hot, then allow it to cool before sealing it. Properly stored, it can last 3-4 days in the fridge or up to a month in the freezer.
Place the leftover pan-seared fish on a lightly greased baking sheet. Broil for 1-3 minutes on each side to reheat it. Leave the oven door partially ajar during cooking.
