Fire Roasted Whole Branzino

Fire Roasted Whole Branzino

I have a genuine love-hate relationship with fish. Some fish I love, others I just can’t stand because, well—they taste like fish. Odd right? That a fish would taste like a fish? In any case, I’m all about the lighter tasting fish, but the fishy fish, nooo thanks.

Enter branzino, which might be the lightest fish ever. Whole roasted branzino doesn’t taste fishy at all, which for me is a good thing. In fact, roasted branzino takes on flavor very well and this fresh fish with lemon, rosemary, and thyme is quickly becoming a favorite around casa de seeker.

You’ll find no shortage of roasted branzino recipes online, all using the oven of course, and those are great too. Today though, we’re not only going to take advantage of the fresh herb and citrus notes, but also the subtle but definitely present flavor the grill brings to this fish.

Before we get into the recipe, I’ll answer a few often asked questions about branzino, and then offer a few tips for cooking branzino on the grill.

Are Branzino and Chilean Sea Bass the Same?

No. Chilean Sea Bass isn’t even a bass actually, and if you’ve ever seen a picture of one, you’d probably have wished you hadn’t. Cleaver marketing put this fish on the map, as Chilean Sea Bass has a much nicer ring to it than Patagonian Toothfish. Branzino on the other hand is a member of the bass family.

They are also very different flavor profiles. As I mentioned earlier, branzino is a very light fish, almost sweet even—and takes on the flavor from herbs and seasoning very well. Chilean Sea Bass is a much hardier fish, with a more robust texture.

What’s The Difference Between Branzino and Branzini?

Nothing! They are the same fish, but depending on what country you’re in, they are called different names. I’ve also heard some refer to more than one branzino as branzini, like branzini is the plural version of the word. I’m no English teacher, but I’m pretty sure that’s not right.

Where to Buy Branzino

I’ve found the best source for buying branzino is online. Some larger grocery store chains with extensive seafood sections have branzino on occasion, but it’s inconsistent at best.

Tips For Roasting Branzino on the Grill

The Placement: The head “end” of the fish will cook slower than the tail end, so when placing the fish on the grill, place the head end towards the fire.

The Temperature: We’ll be roasting the fish at two different temperatures, 425°F and 500°F. Be sure to remove the fish from the grill while it’s heating from 425° to 500°, or the fish will overcook.

The Flavor: If you want to kick this up even more, feel free to add a wood chunk to the coals and infuse some smoke to the fish. I recommend a mild wood like pecan as the fish takes smoke quickly and more intense woods will overpower it.

The Prep: If at all possible, have your fishmonger gut and remove the scales from the fish. Neither are hard to do, but both are messy, and the scales get everywhere.

Fire Roasted Whole Branzino Recipe

Serves: 3 | Prep Time: 15 minutes | Cook Time: 20 minutes total

Ingredients
2-3 fresh whole branzino, cleaned and scaled
12 cherry tomatoes
5 lemons
6 sprigs rosemary
12 sprigs fresh thyme
¼ cup extra virgin olive oil
sea salt and fresh cracked pepper to taste

How to Roast Branzino

Step 1: Light your grill and set up for two zone heating. Using a reliable leave-in thermometer, establish grill temperature at 425°F.

Step 2: Using a sharp knife, make three to five 1/4″ deep slices (oriented top to bottom and spaced evenly) on the side of each fish. Flip the fish, and make an equal number of slices. Evenly coat the inside and outside of all three fish with olive oil, ensuring the oil penetrates into the slices in the sides of the fish. Season with salt and pepper, both inside the cavity and on the skin.

Step 3: Slice two lemons into 9 slices. Cut the remaining lemons in half and set aside.

Step 4: Stuff the cavity of each fish with three slices of lemon, two rosemary sprigs, and four sprigs of fresh thyme.

Then, using butchers twine, tie the fish closed. Toss tomatoes in remaining olive oil and sea salt.

Step 5: Place the fish and tomatoes on a parchment paper-lined sheet pan, and transfer to the grill over indirect heat. Close the grill’s lid and allow to roast for 10-12 minutes.

Step 6: Remove fish from the grill and quickly stoke coals to raise the grill’s temperature to 500°F. Return fish to the indirect heat zone of the grill, and place the lemon halves cut-side down over the direct heat zone of the grill. Close the lid and allow to roast for 5 minutes.
