Ingredients
Ingredient Quantities in Detailed Table
| Ingredient | Quantity | Description / Notes |
|---|---|---|
| Plaice fillets | 400g | Fresh, skinless, boneless fillets ideally obtained from a trusted fishmonger |
| Fresh spring onions | 300g | Trimmed and sliced in half lengthwise for even cooking |
| Extra virgin olive oil | To taste (approximately 2-3 tablespoons) | For drizzling and greasing the baking tray |
| Fine salt | To taste | Adjust according to preference and dietary needs |
| Black pepper | To taste | Freshly ground for best flavor |
| Fresh rosemary | 1 sprig | Leaves finely chopped or minced |
| Fresh sage | 4 leaves | Chopped finely |
| Fresh thyme | 2 sprigs | Leaves stripped and chopped |
| Lemon | 1 whole | Rinsed, sliced into thin rounds, and zest if desired |
Instructions
Step 1: Preparing the Ingredients
Begin by carefully preparing your fresh produce. Rinse the spring onions under cool running water to remove any dirt or debris. Trim off the root ends using a sharp knife, ensuring a clean cut. Next, cut the green tops of the onions, but save some for garnishing if desired. Slice each onion in half lengthwise to facilitate even cooking and maximize flavor absorption during baking.
For the herbs, take each sprig of rosemary, sage leaves, and thyme, and finely chop them. Use a sharp knife to mince the herbs into small, fragrant pieces. This step is crucial because finely chopped herbs distribute their aromatic oils more effectively, infusing the fish with a balanced herbaceous flavor.
Wash the lemon thoroughly. Pat dry with a clean cloth or paper towel. Slice the lemon into thin rounds, which will be layered around and atop the fish. Optionally, zest the lemon before slicing for an extra burst of citrus flavor to be used later if desired.
Step 2: Preparing the Baking Tray and Fillets
Preheat your oven to 220°C (static mode). While the oven heats up, prepare your baking tray by lightly greasing it with a generous drizzle of extra virgin olive oil. Use a brush or a paper towel to evenly coat the surface, ensuring the fish will not stick and will develop a beautiful, golden crust during baking.
Arrange the plaice fillets on the prepared tray. Place them flat and spaced apart adequately to allow heat circulation for even cooking. Lightly season each fillet with a pinch of fine salt and freshly ground black pepper. This initial seasoning enhances the natural flavor of the fish and helps balance the aromatic herbs added later.
Step 3: Adding Aromatics and Herbs
Sprinkle the chopped herbs evenly over the fillets, pressing them lightly onto the surface to adhere. The herbs will release their fragrant oils during baking, infusing the fish with complexity and depth. Arrange the halved spring onions around and on top of the fillets, creating a bed of sweetness that will caramelize slightly and add a lovely texture. Layer the lemon slices over and around the fish, ensuring each piece is complemented by citrus aroma and flavor.
Step 4: Baking the Fish
Place the baking tray in the preheated oven. Bake for approximately 20 minutes. The timing may vary slightly depending on the thickness of your fillets and oven calibration. The fish is done when it turns opaque, flakes easily with a fork, and the onions are tender and slightly caramelized. The lemon slices should be softened and fragrant, adding brightness to the dish.
Step 5: Finishing Touches and Serving
Once baked, carefully remove the tray from the oven. Drizzle a little extra virgin olive oil over the hot fillets to enhance richness and give a glossy finish. This step also adds a layer of flavor complexity that complements the herbs and citrus.
Transfer the fillets carefully onto serving plates. You can garnish with additional lemon slices or a sprinkle of fresh herbs if desired. Serve immediately for the best flavor and texture. Pair with simple side dishes such as a fresh green salad, roasted vegetables, or crusty bread for a complete meal.
Preparation Tips
- Choosing fish: Opt for fresh, high-quality plaice fillets, preferably sourced from sustainable fisheries. Fresh fish should have clear eyes, firm flesh, and a mild scent.
- Herb variations: Feel free to experiment with other herbs such as parsley, dill, or basil to customize the flavor profile.
- Layering flavors: For an extra aromatic touch, lightly brush the fish with garlic-infused olive oil before adding herbs.
- Cooking time: Adjust the baking time based on the thickness of your fillets. Thinner fillets may cook faster, so keep an eye on them to prevent overcooking.
- Additional seasonings: For a subtle spicy kick, sprinkle red pepper flakes or paprika before baking.

Tips and Tricks
- Use fresh herbs: Fresh herbs provide a vibrant aroma and flavor unmatched by dried varieties, especially when baking.
- Room temperature fish: Let the fillets sit at room temperature for 10-15 minutes before baking to ensure even cooking.
- Cover for moisture: If you prefer a more moist fillet, loosely cover with aluminum foil during baking. Remove the foil in the last 5 minutes for a crispy top if desired.
- Flavor infusion: For added depth, consider marinating the fish with lemon juice, herbs, and a drizzle of olive oil for 30 minutes prior to baking.

Improvements
- Add a splash of white wine or vermouth before baking for extra depth
