Ingredients

For the perfect flounder dish, fresh ingredients are non-negotiable. Flounder’s delicate flavor thrives with complementary flavors, so quality is key. Here’s what you’ll need to make this standout recipe, along with insider tips and easy swaps to keep it stress-free.

• Fresh flounder fillets – Look for firm, translucent fillets with a mild sea scent. Avoid any that smell overly fishy. If flounder isn’t available, sole or tilapia are great substitutes.
• Salt and freshly ground black pepper – These basics are essential for seasoning; don’t skimp.
• Lemon – Fresh lemon juice and zest add a bright, tangy kick. Bottled juice just doesn’t compare here.
• Fresh parsley – A must for that final garnish and a burst of freshness. Dried parsley works in a pinch but won’t have the same impact.
• Garlic – Freshly minced garlic brings depth and aroma. Powder can work, but fresh is ideal.
• Butter – Unsalted butter for sautéing guarantees rich, buttery flavor. If you’re out, olive oil is a solid alternative.
• All-purpose flour – A light coating for the fish guarantees a golden, crispy exterior. Gluten-free flour works if needed.
• White wine or chicken broth – For deglazing the pan and creating a light, flavorful sauce. If avoiding alcohol, stick with broth.
• Capers – Optional, but they add a briny, gourmet touch. If you’re not a fan, skip them or substitute with chopped olives.

Pro tip: If you’re feeling fancy, sprinkle a pinch of smoked paprika or red pepper flakes for a subtle smoky or spicy kick.

Fresh herbs like dill or chives also make excellent garnishes for extra flair.

How to Make the Best Lemon Herb Flounder Recipe

1. Preheat your oven to 375°F (190°C) – Guarantees even cooking and a perfectly flaky texture.
• *Pro Tip:* Use an oven thermometer for accuracy—home ovens often run hot or cold.
2. Pat the flounder fillets dry with paper towels – Removes excess moisture so the seasoning sticks better and prevents steaming.
• *Watch-Out:* Wet fish won’t brown properly in the pan.
3. Season both sides of the fillets with salt and pepper – Enhances natural flavors evenly.

4. Heat olive oil in a large skillet over medium-high heat – A hot pan guarantees a crispy exterior.

5. Sear fillets for 2–3 minutes per side – Gives a golden crust while keeping the inside tender.
• *Flexibility:* Adjust time slightly for thicker/thinner fillets.
6. Transfer skillet to the oven and bake for 5–7 minutes – Finishes cooking gently without overcooking.
• *Pro Tip:* Use an oven-safe skillet to avoid extra dishes.
7. Top with lemon zest, fresh herbs, and a drizzle of melted butter – Brightens flavors and adds richness.

Chef Tips

When preparing flounder, I always recommend patting the fillets dry before cooking—it helps achieve a crispier texture.

Use a hot skillet or grill to sear quickly, ensuring the fish stays tender. Season lightly to let the flounder’s delicate flavor shine.

Avoid overcooking; it’s done when it flakes easily. Pair with fresh herbs or a squeeze of lemon for brightness.

These tips make perfect flounder every time.
