This Pan Seared Sea Bass is drizzled with a buttery Lemon Pepper Sauce and adorned with a Fennel Stir-Fry. Together, these elements make for a beautiful presentation. Quick and easy, this healthy main course is perfect for casual entertaining and also great on busy weeknights.
Pan Seared Sea Bass only takes about 4 minutes to cook. And with a quick lemon pepper sauce and fennel stir fry, all made in the same pan, it's an incredibly satisfying and delicious dish.
Recipes with sea bass are a great choice for a group with varying palates because it's a mild fish that most people love. And this particular recipe is always a hit!
- sea bass fillets - Always buy the freshest fish possible. If you have a specialty fish market near you, that's probably your best bet. Pan seared Sea Bass is great with the skin left on for ultimate crispiness.
- olive oil - Regular or extra virgin.
- lemon - Use Meyer lemons if they're in season.
- unsalted butter - It's a good idea to cook (and bake) with unsalted butter, so you can control the amount of salt in a recipe.
- fennel bulb - It's great if you can get them with the stems attached with their leaves (feathery fronds), then you can use them in the stir fry and/or for garnish.
- red bell pepper - A good pepper should be firm, deeply colored and slightly shiny.
- onion - Choose firm onions that are heavy for their size, and without bruises.
- Kosher salt - I cook with Kosher salt. I prefer it for a few reasons: its larger flake size, it's less refined and usually doesn't contain additives, and it does a great job enhancing the flavor of foods without making them taste salty.
- black pepper - Freshly ground if possible.
(See recipe card for quantities.)
- It's imperative the pan be very hot when the fish hits it. That's the key to searing, as it almost instantly begins to caramelize and form a "crust." If you don't hear a strong sizzling sound when the fish hits the pan, it's not hot enough yet.
- Do not crowd the pan. If you do, you won't get the browning and caramelization we want. In my 12-inch cast iron skillet, I can sear two average-sized sea bass fillets at a time. (Each fillet is about 6-ounces.)
- Do not cook the fish ahead of time. It'll only take a few minutes and is best right out of the pan.
- The stir-fry is on the crunchy side. If you prefer it softer, cook it for another few minutes.
- If you choose not to eat the skin, once cooked, it can very easily be removed.
- The fish is delicious even without the vegetables -- with just a drizzle of the lemon pepper sauce.
- If you can't get Sea Bass, Cod and Grouper are both excellent substitutes.
- You can use kohlrabi, broccoli or zucchini instead of fennel, if you prefer.
- In addition to the red, yellow and orange bell peppers would also be pretty, or any combination thereof.
How to Make It
- Prep the vegetables and set aside.
- Add the olive oil to a large sauté pan — ideally cast iron. Preheat the pan over high heat on the stove.
- Season both sides of the fillets with salt and pepper.
- Skin side down, gently lay the fillets in the pan. As they hit the pan, you should hear a strong sizzling sound. If you don’t, wait until you do.
- After about 3 minutes, the skin side should be golden and crispy.
- Turn the heat to medium, flip the fillets over to finish the cooking for about 1 minute, with the skin side up.
- Remove the fillets from the pan and set them aside on a serving platter and cover lightly with foil.
- With the heat still at medium, add the butter, lemon juice, pepper, and a sprinkle of salt to the pan. Let the butter melt and swirl the pan. Brown the butter by cooking it for another couple minutes. Spoon a bit of this lemon pepper sauce on each fillet, leaving about half of it in the pan. If you don't want the fennel stir fry, drizzle all of the lemon pepper sauce over the fish and you're done.
- Turn the heat up to medium-high and add the onion, peppers and fennel to the pan. Sauté for about 5 minutes, stirring from time to time.
- Season with salt and pepper to taste, spoon it over the fish and serve.
(More detailed instructions are in the recipe card below.)
- This is a year-round main course that can be served with an array of other dishes, and it's also a great stand alone dish.
- The fennel stir fry with red peppers is a side dish in and of itself, and it's a beautiful topping for the fish.
- While potatoes are more commonly paired with meat and poultry, pan seared sea bass is incredibly delicious with a serving of mashed potatoes beneath it.
- It's also fantastic with rice dishes and all sorts of salads.
- And sometimes the addition of a warm crusty loaf of bread is all we need.

Making it Ahead
The seared Sea Bass dish is best when it's made as close to serving time as possible. That's when it'll be the most flaky and succulent.
The lemon pepper sauce and the fennel stir fry are both made in the same pan as soon as the fish is removed.
Sea Bass has a mild, delicate flavor that’s subtly sweet. It’s light and flaky with a bit of a meaty consistency.
Fresh fennel bulb has a mild anise or licorice-like flavor with notes of celery. Raw, it's quite crunchy, and when it's cooked, it becomes soft, the flavor mellows a bit, and becomes slightly sweet.
I hope you enjoy this sea bass recipe as much as my family and I do!

That looks flaky and so juicy! The crispy skin side is the best :-))
Agreed! 🙂 Thanks, Angie. ~Valentina
I adore simple, flavorful, healthful fish dishes like this, Valentina. And nothing like a fish that sears in just 4 minutes! Love the fennel in the stir fry too.
Thanks so much, Marissa! Enjoy. 🙂 ~Valentina
Darling Valentina - this dish may sound American but methinks it is a given delight all over at least the Western world - simple and healthy but fill of flavour. I do not usually cut my vegetables so fine but can see how delightful it looks on the plate, so . . . and I just love fennel . . . yum !!
Thanks, Eha. I love fennel too, and I don't cook with it enough. 🙂 ~Valentina
Beautiful. I just wish I loved fennel more. I know I’m in the minority, but it’s a strong flavor to me. I even have grown it and forced myself to use it! I’ll keep trying…
Hi, Mimi. I think fennel is a bit of an acquired taste. Don't eat anything you don't like -- life is too short. 🙂 ~Valentina

Fennel and seafood are a wonderful combination. Your fish is definitely healthy and very flavorful.

Hi Dawn. Thanks so much. Hope you love it! :-: ~Valentina

This looks absolutely delicious! And so simple - and I love all the ingredients - fish and fennel make such food partners! Sea bass is hard to find here - but we get great grouper from México, so thanks for that substitution idea.
Thanks, David. I often forget about fennel -- I don't think it gets enough attention. Enjoy! 😉 ~Valentina
