This is the kind of elegant, restaurant-quality meal that makes you feel like you're treating yourself on a weeknight. Chilean sea bass is one of those special fish—buttery, flaky, and rich—and when you pan-sear it with lemon, parsley, and garlic, it becomes absolutely sublime. The key here is getting that gorgeous golden crust on the outside while keeping the inside tender and moist, and it's easier than you think. We're serving it alongside crispy roasted potatoes that are fluffy inside and perfectly golden outside, plus roasted broccoli with lemon and Parmesan, and roasted radishes that transform into something sweet and mild when they hit high heat. The whole meal works for everyone at the table—the fish is the star, and the vegetables are so good that nobody feels like they're missing out. This is one of those meals where simple techniques and quality ingredients come together to create something really special, and it's all done in about 35 minutes with just a skillet and a sheet pan. Perfect for when you want to feel fancy without the fuss.
Lemon-Herb Chilean Sea Bass with Roasted Vegetables & Crispy Potatoes
Ingredients
Method
- Preheat oven: Preheat oven to 425°F. Line two baking sheets with parchment paper.
- Prep all ingredients: Peel and cube 3 lbs russet potatoes into 1-inch pieces. Cut 2 heads broccoli into florets. Trim and halve 1 bunch radishes. Mince 3 cloves garlic. Zest and juice 1 lemon (reserve ½ lemon juice for vegetables). Chop ¼ cup fresh parsley. Pat 4 sea bass fillets dry with paper towels and season both sides with salt and pepper. Set aside.
- Roast the potatoes: On one baking sheet, toss cubed potatoes with 3 tablespoons olive oil, 1 teaspoon garlic powder, salt, and pepper. Spread in a single layer, making sure they're not crowded. Roast for 30-35 minutes, flipping halfway through, until golden brown and crispy on the outside, fluffy on the inside.
- Roast the vegetables: On the second baking sheet, toss broccoli florets and halved radishes with 3 tablespoons olive oil, salt, and pepper. Spread in a single layer. After potatoes have been roasting for 10 minutes, add this sheet to the oven. Roast for 20-25 minutes until broccoli is tender with crispy edges and radishes are golden and caramelized.
- Finish the vegetables: When vegetables come out of the oven, immediately squeeze juice of ½ lemon over them and sprinkle with ¼ cup grated Parmesan cheese. Toss gently and keep warm.
- Pan-sear the sea bass: About 10 minutes before vegetables are done, heat 2 tablespoons olive oil in a large skillet over medium-high heat. Once hot and shimmering (but not smoking), carefully place sea bass fillets in the pan, skin-side down if they have skin. Don't move them! Let them cook undisturbed for 4-5 minutes until golden and crispy on the bottom.
- Flip and finish: Carefully flip the fillets. Add 2 tablespoons butter and 3 cloves minced garlic to the pan. As the butter melts, tilt the pan and use a spoon to baste the fish with the garlicky butter. Cook for another 3-4 minutes until fish is opaque and flakes easily with a fork (internal temp should be 145°F).
- Add lemon and herbs: Remove pan from heat. Add lemon zest, juice of ½ lemon, and ¼ cup chopped fresh parsley to the pan. Spoon the lemony butter sauce over the fish.
- Serve: Divide crispy potatoes, roasted broccoli, and roasted radishes among 4 plates. Place a sea bass fillet on each plate and drizzle with the lemon-herb butter from the pan. Garnish with extra fresh parsley and serve with lemon wedges on the side.
Notes
- Look for Chilean sea bass (also called Patagonian toothfish)
- Should smell fresh and ocean-like, not fishy
- Flesh should be firm and moist
- If unavailable, halibut or cod work well PERFECT SEAR:
- Make sure fish is completely dry before cooking—moisture prevents browning
- Don't move the fish once it's in the pan—let it develop that crust
- The pan should be hot but not smoking
- If fish sticks, it's not ready to flip yet CRISPY POTATO SECRET:
- Cut potatoes uniformly so they cook evenly
- Don't crowd the pan—they need space to crisp up
- High heat is key for that golden, crispy exterior
- Flipping halfway ensures even browning ROASTED RADISHES:
- Radishes transform when roasted—they lose their sharp bite and become sweet and mild
- They're similar to roasted turnips in texture
- The caramelization brings out natural sweetness BROCCOLI TIPS:
- High heat creates crispy, caramelized edges
- The lemon brightens the flavor
- Parmesan adds umami richness TIMING:
- Start potatoes first since they take longest
- Add vegetables to oven 10 minutes later
- Start fish about 10 minutes before vegetables are done
- Everything finishes at the same time MAKE IT SPECIAL:
- This is an elegant meal perfect for guests
- The presentation is beautiful
- The lemon-herb butter makes it restaurant-quality
