Easy Garlic Parmesan Baked Flounder Recipe (20 mins)

Easy Garlic Parmesan Baked Flounder combines thin flounder fillets with zucchini and onions, all seasoned with garlic, oregano, paprika, cumin, and lemon juice, then baked and topped with melted Parmesan cheese. This light, flaky fish dish offers balanced herbal and citrus notes with a slight spice touch, suited for a healthy, quick main course.

Description

This recipe features flounder fillets baked alongside zucchini halves and sliced red onions. The fish and vegetables are seasoned with garlic, dried oregano, paprika, and cumin, enhanced by fresh lemon juice and olive oil. After an initial baking period, grated Parmesan cheese is sprinkled on top to melt and enrich the dish with a savory layer. The thin flounder cooks quickly, requiring careful timing to avoid overcooking.

The resulting dish has a mild, flaky texture from the fish complemented by tender roasted vegetables. The mix of herbs and spices provides aromatic flavors without overwhelming the delicate fish. The lemon juice adds brightness while the Parmesan adds richness and a slightly nutty finish.

This baked flounder pairs well with herby boiled or smashed potatoes and green sides like roasted broccoli, Greek green bean salad, or asparagus salad, making a balanced, colorful meal.

Use fresh or thawed flounder, pat dry before cooking to reduce moisture. Leftovers keep up to two days refrigerated, and reheat gently in a skillet. If baking frozen fillets, thaw thoroughly overnight. Adding Parmesan earlier may be needed if the fish cooks faster than expected.
