Enjoy a light, vibrant, and quick seafood dinner with Herb Crusted Tilapia and Roasted Zucchini. Mild tilapia fillets are coated in an herb-infused panko crust and baked on a single sheet pan alongside tender, caramelized zucchini slices for a nutritious meal ready in under 25 minutes.
The secret to crisp tilapia alongside perfectly roasted zucchini is Baking at High Heat (425°F / 220°C) and Slicing the Zucchini into Thick ½-Inch Half-Moons. Tilapia cooks very quickly (10 to 12 minutes), so cutting the zucchini slightly thicker and patting the fish dry ensures both finish cooking at the exact same time without the zucchini turning watery or the fish drying out.

- Vegetables: 2 medium zucchini, sliced into ½-inch thick half-moons.
- Herb Panko Crust: ¾ cup Japanese panko breadcrumbs, 2 tablespoons melted butter (or olive oil), 2 tablespoons finely chopped fresh parsley, 1 tablespoon fresh dill (or chives), 1 teaspoon garlic powder, ½ teaspoon onion powder, 1 teaspoon lemon zest, salt, and black pepper.

Step-by-Step Instructions
1.Prep Oven & Sheet Pan:3 min.
Preheat your oven to 425°F (220°C) and line a large, rimmed baking sheet with parchment paper or heavy-duty aluminum foil.
2.Mix Herb Panko Crust & Prep Zucchini:4 min.
In a small bowl, whisk together ¾ cup panko breadcrumbs, 2 tablespoons melted butter, chopped parsley, dill, garlic powder, onion powder, lemon zest, ½ teaspoon salt, and ¼ teaspoon black pepper until moist and fragrant. Slice 2 medium zucchini into ½-inch thick half-moons.
3.Bread Tilapia & Season Zucchini:4 min.
Pat 4 tilapia fillets completely dry with paper towels. Place the zucchini half-moons on one half of the sheet pan, toss with 1 tablespoon olive oil, salt, and pepper, and spread in a single layer. In a shallow bowl, whisk 1 egg with 1 tablespoon Dijon mustard. Dip each tilapia fillet in the egg wash, press firmly into the herb panko mixture, and lay on the empty side of the pan.
4.High-Heat Bake:12 min.
Bake at 425°F (220°C) for 10 to 12 minutes, until the herb panko crust is golden brown and the tilapia flakes easily with a fork (145°F / 63°C internal temperature) and the zucchini is tender-crisp.
5.Garnish & Serve Warm:1 min.
Remove from the oven, squeeze fresh lemon juice over the fish and zucchini, and serve hot!
Expert Tips for Success
- Pat Tilapia Completely Dry: Tilapia holds a lot of surface moisture. Pressing the fillets dry with paper towels before dipping in egg wash prevents the breadcrumbs from turning soggy.
- Don’t Slice Zucchini Too Thin: Thinly sliced zucchini releases excess moisture quickly and gets mushy. Keeping the half-moons ½-inch thick ensures a crisp-tender bite.
- Use Panko Instead of Regular Breadcrumbs: Panko flakes stay light and crispy in the oven, giving you a fried-like crunch without deep frying.
