06 - 2 tablespoons olive oil
→ Sauce
07 - 4 tablespoons unsalted butter
08 - 2 tablespoons fresh lemon juice

# Step-by-Step Guide:
01 - Pat flounder fillets dry with paper towels. Season both sides evenly with kosher salt and freshly ground black pepper.
02 - Place all-purpose flour on a shallow plate. Coat each fillet lightly in flour, shaking off excess to ensure a thin, even coating.
03 - In a large nonstick skillet, combine 2 tablespoons unsalted butter and 2 tablespoons olive oil over medium-high heat until the butter becomes foamy.
04 - Add flounder fillets to the hot skillet in a single layer, working in batches if necessary. Cook 2 to 3 minutes per side until golden brown and just cooked through. Transfer cooked fillets to a warm serving platter.
05 - Wipe out the skillet with a clean cloth. Add the remaining 4 tablespoons unsalted butter over medium heat. Cook for 2 to 3 minutes until it turns golden brown and develops a nutty aroma, stirring occasionally.
06 - Remove from heat. Immediately stir in 2 tablespoons fresh lemon juice and 2 tablespoons chopped flat-leaf parsley.
07 - Spoon the warm browned butter sauce over the flounder fillets. Serve immediately with lemon wedges on the side.
