Crispy Skin Wild Black Bass with Beurre Blanc, Roasted Baby Potatoes, & Charred Broccolini
There’s a moment in every home cook’s journey where a frustration turns into a discovery. Mine came while chasing my love of Peruvian ceviche.
While developing my recipe for Wasabi Ceviche, I ran into a wall that I suspect a lot of home cooks hit: finding genuinely high-quality white fish suitable for raw preparation locally. Salmon and tuna? Easy. Every counter in town has something labeled “sushi grade.” But a clean, firm, raw-eating white fish? That search came up empty again and again.
So I took it online, and what started as frustration turned into one of the best sourcing discoveries I’ve made in years: Browne Trading Co.
Since finding them, I’ve ordered all kinds of exceptional ingredients, but the wild Black Sea Bass fillets are what stopped me in my tracks. They arrived pristine, firm, and genuinely sushi grade. I could have sliced it straight into ceviche or sashimi. Instead, I decided to do something different: sear it, and build a dish around that impossibly crisp skin.
That decision became this recipe.
What “Sushi Grade” Actually Means (and Doesn’t)
“Sushi grade” and “sashimi grade” get thrown around like they’re an official stamp of approval — they aren’t. There’s no USDA or FDA certification behind the term. No government inspector signs off on a fish and declares it “sushi grade.” It’s a designation the seafood merchant applies themselves, based on their own standards for freshness, handling, and sourcing.
The one place federal regulation does enter the picture is around parasite risk. The FDA has freezing guidelines — commonly citing something like freezing at -4°F for 7 days, or -31°F until solid followed by storage at -31°F for 15 hours — designed to kill parasites in fish destined to be eaten raw. But even that isn’t a blanket rule; some species (certain tuna, most farmed salmon) are considered low-risk enough to be exempt.
In other words: “sushi grade” tells you the seller believes the fish is safe to eat raw at the moment you bought it. It says nothing about what happens after that. The responsibility shifts to you the second it’s in your hands. I bring a cooler packed with ice every single time I pick up fish from a trusted seafood counter — whether I plan to eat it raw or cook it — because keeping the cold chain unbroken is what actually keeps you safe, not the label on the package.
There’s a lot more nuance to sourcing raw-grade seafood responsibly, but that’s a deep dive for another post.
Why Black Sea Bass
Black Sea Bass is one of those fish that rewards you the moment it hits a hot pan. The skin is thin but sturdy, which means it renders down to something genuinely shatter-crisp instead of chewy or rubbery, a common failure point with thicker-skinned fish. The flesh underneath stays snow-white, flaky, and mild enough to let a proper beurre blanc do what it does best: coat, not compete.
The Technique: Getting Genuinely Crispy Skin
Crispy skin is one of the most-requested, most-botched techniques in home cooking. A few things make the difference between shatter-crisp and sad-and-soggy:
- Dry the skin completely. Pat it down with paper towels, then let it sit uncovered in the fridge for at least 20–30 minutes (longer if you have time) so surface moisture evaporates. Wet skin steams instead of crisping.
- Score lightly. A few shallow cuts through the skin (not into the flesh) help prevent curling and let the skin render more evenly.
- Do not use a non-stick pan. Cast iron is best. Get the oil smoking hot, then put the fish skin side down, and don’t move it. Resist the urge to nudge or flip early. The fish will release naturally once the skin has properly rendered and crisped. Forcing it early is how you tear the skin and leave it stuck to the pan.
- Press gently for the first 30–60 seconds. A fish spatula with light, even pressure keeps the fillet flat against the pan so the whole surface makes contact and crisps evenly, instead of curling up in the center.
- Cook it almost all the way through on the skin side. Black bass fillets are thin enough that you can get 80–90% of the cook on the skin side alone, then just finish with a brief flip at the end. This maximizes crisp time without overcooking the flesh.
Building the Beurre Blanc
A classic French beurre blanc is deceptively simple, a reduction of white wine and shallots, mounted with cold butter off the heat – but it rewards patience. A few tips that made a difference here:
- Keep the wine-shallot reduction assertive; it needs to carry flavor through all that butter.
- Mount the butter off direct heat, adding it a few cubes at a time and swirling constantly. If the sauce breaks (goes oily/separated), it’s almost always because the pan got too hot.
- Capers and a finish of fresh chives brighten what could otherwise be a very rich sauce. The brininess cuts right through the butter and plays beautifully against the crispy fish skin.
Charred Broccolini – Don’t Be Afraid of the Black Bits
Broccolini wants real, aggressive heat. The move here is a two-stage oven method: roast first to get the stems tender, then finish under the broiler to actually char the floret tips. Roasting alone won’t get you that dark, smoky char. You need the direct top-down heat of the broiler for the last few minutes, watched closely so it colors without burning. A squeeze of fresh lemon at the end brightens the char and balances the richness of the butter sauce.
Roasted Baby Potatoes
Simple, high-heat roasting with olive oil, thyme, and smashed garlic. They go in first since they take the longest, and the broccolini joins partway through so everything lands hot and ready at the same time.

Ingredients
Fish
- 2 wild black bass fillets skin-on, about 6 ounces each
- 1 teaspoon kosher salt
- 1 tablespoon ghee for searing
Roasted Baby Potatoes
- 1 pound baby red and yellow potatoes
- 2 tablespoons olive oil
- 1 teaspoon kosher salt
- ½ teaspoon black pepper freshly cracked
- 2 sprigs fresh thyme
- 1 garlic clove smashed
Charred Broccolini
- 6 ounces broccolini trimmed
- 1 tablespoon avocado oil
- 2 garlic cloves thinly sliced
- ½ teaspoon red pepper flakes
- 1 lemon wedge for finishing
Beurre Blanc
- 1 shallot minced
- 3 tablespoons dry white wine
- 1 tablespoon fresh lemon juice
- 3 tablespoons unsalted butter cold, cubed
- 1 tablespoon capers drained
- 1 tablespoon fresh parsley chopped
Instructions
- Dry the fish skin: 8-10 hours before cooking (or the night before), place the bass fillets skin side up on a plate, uncovered, in the refrigerator. The airflow will dry the skin to a taut, papery texture — the foundation of a truly crispy crust. Do not salt at this stage.
- Roast the potatoes: Preheat oven to 425°F. Toss the baby potatoes with the olive oil, salt, pepper, thyme, and smashed garlic. Spread in a single layer on a sheet pan. Roast for 20-25 minutes until deeply golden and fork-tender.
- Roast the broccolini: About 10 minutes before the potatoes finish, toss the broccolini with the avocado oil, sliced garlic, red pepper flakes, and a pinch of salt. Spread in a single layer on a second sheet pan and add to the oven alongside the potatoes. Roast for 8-11 minutes until the stems are tender and beginning to color, then move the rack to the top position and broil on high for 2-3 minutes, watching closely, until the floret tips are dark and charred. Squeeze the lemon wedge over the top and keep warm.
- Prep the fish: Remove the bass fillets from the fridge 15 minutes before cooking. Score the skin with shallow slits just deep enough to break the membrane, about ⅛ inch deep, spaced ½ inch apart. This prevents curling and maximizes crispiness on thin fillets. Pat the skin dry one final time with a paper towel. Season both sides with the kosher salt right before cooking.
- Start the sauce and sear the fish simultaneously: In a small saucepan over medium heat, cook the minced shallot for 3 minutes. Add the white wine and lemon juice and reduce until nearly a syrup, about 2 minutes. Meanwhile, heat a separate stainless steel or cast-iron skillet over high heat until nearly smoking. Add the ghee and swirl to coat. Lay the fillets skin side down. Immediately press each fillet firmly with a spatula for 10 seconds to ensure full skin contact. Do not move them. They will release when ready.
- Finish the sauce: Remove the saucepan from heat. Whisk in the cold cubed butter, one cube at a time, until the sauce is glossy and emulsified. Stir in the capers and parsley. Taste and adjust salt. Keep warm on the lowest possible heat or simply off heat. The emulsion will hold for a few minutes.
- Finish the fish: After 2 minutes skin side down, flip the fillets, but don't force them to release. Cook the flesh side for just 30-45 seconds. If they took longer to release, just hit them for 20 seconds on the other side. Immediately transfer the fish to a warm plate so they don't overcook in the pan. Place skin side up.
- Plate and serve: Place the broccolini in the center of the plate. Place the fish on top of the broccolini. Spoon the beurre blanc alongside or around the fish. You can drizzle a tiny bit over the skin, but not too much or it will go soft. Add the roasted potatoes. Serve at once.
