Ingredients

Instructions

Preparing the Ingredients

Begin by gathering all your ingredients and preparing them to streamline the cooking process. Wash the lemon thoroughly, especially since it’s unwaxed and suitable for direct juice extraction and slicing. Slice the lemon thinly, then halve the fruit to extract fresh lemon juice using a reamer or citrus press. Set aside in a small bowl.

Clean the fish thoroughly under cold, running water. Use your hands to gently remove any remaining scales or impurities. Pat dry with paper towels. Season the fish generously with salt, pepper, and drizzle with lemon juice. Inside the fish cavity, place a few lemon slices and herbs if you like extra flavor. Set aside to marinate briefly while preparing vegetables.

Preparing Vegetables and Herbs

Peel and wash the fennel bulb. Using a sharp knife or mandoline, slice the fennel into thin, uniform slices to ensure even cooking and a delicate texture. Rinse the tomatoes, trim off the stem and core, and slice into rounds approximately 0.5 cm thick. If desired, remove excess seeds to avoid excess moisture in the dish.

Drain the olives and slice them thinly to distribute their briny flavor evenly. Wash the sprigs of rosemary and thyme, then pat dry. Chop the herbs roughly, ensuring they are not fine minced but coarse enough to impart flavor without overwhelming the dish.

Cooking the Vegetables

In a large skillet or frying pan, heat the plant-based creamer over medium heat until warm but not boiling. Add the fennel slices and cook, stirring occasionally, until the fennel begins to soften but retains some bite—approximately 5-7 minutes. You want the fennel to become tender yet still vibrant. Adjust the heat as needed to prevent burning or sticking.

When the fennel is semi-soft, add the sliced tomatoes and olives to the pan. Stir gently to combine, then sprinkle the chopped herbs over the mixture. Pour the heavy cream over the vegetables, stirring gently to coat everything evenly. Allow the mixture to simmer for another 3-4 minutes, just enough to meld flavors and warm through.

Preparing the Baking Dish

Preheat your oven to 200°C (around 390°F). Line a large baking sheet or baking dish with parchment paper or lightly grease it with a small amount of oil or butter to prevent sticking.

Spread the cooked vegetable mixture evenly across the bottom of the dish. Distribute the mixture uniformly, creating a bed that will support the fish. Nestle the prepared dorade on top of the vegetable bed, ensuring they are spaced adequately to allow heat circulation. Inside each fish cavity, place additional lemon slices and a few sprigs of herbs for aromatic infusion.

Baking the Dish

Cover the entire dish tightly with aluminum foil, ensuring a secure seal to trap steam and keep the fish moist during baking. Place the dish in the preheated oven, allowing it to cook for approximately 20 minutes. During this time, the fish will become tender, flavors will meld, and the vegetables will finish cooking to softness.

Check the fish at the 20-minute mark. If you’re using thick-cut fish or prefer a more cooked result, extend baking time by an additional 5-10 minutes, verifying that the fish flakes easily with a fork and the vegetables are tender. Do not overcook, as fish can become dry if baked excessively.

Preparing the Cheddar Potato Gratin

While the fish is baking, prepare the potato gratin. Peel and thinly slice potatoes using a mandoline or sharp knife, aiming for uniform thickness (~2-3 mm). Grate the cheddar cheese and set aside.

Once the fish has baked for roughly 15 minutes, sprinkle the grated cheddar evenly over the potato slices layered on top of the gratin dish. Return the dish to the oven, uncovered this time, and bake for an additional 15-20 minutes or until the cheese is melted, bubbly, and golden brown. If you prefer a crispy crust, switch to broiler mode for the last 2-3 minutes, watching carefully to prevent burning.

Final Assembly and Serving

Remove the fish and gratin from the oven once the gratin has a crispy, golden crust and the fish shows signs of being perfectly cooked—opaque flesh and flaky texture. Carefully transfer the fish to a serving platter if desired.

Let the gratin rest for a few minutes, then serve slices with a generous amount of the cheesy potato topping alongside the baked fish with vegetables. Garnish with additional herbs or lemon wedges if desired for extra freshness.

Preparation Tips

• Uniform slices: Use a mandoline for even potato and vegetable slices to ensure consistent cooking and aesthetic appeal.
• Marinate fish: Let the fish sit in lemon and herb marinade for at least 15-20 minutes to enhance flavor penetration.
• Pre-cook vegetables: Softening fennel and tomatoes slightly before baking helps prevent excess moisture and ensures flavor integration.
• Cheddar topping: Use a high-quality sharp cheddar for a bold, rich flavor and a crispy crust.
• Cooking fish: To prevent overcooking, monitor the fish closely; it should flake easily but still retain moisture.
• Cheese gratin: For a perfect crust, finish under the broiler, but watch closely to avoid burning.

Nutritional Information

Tips and Tricks

• For a richer flavor, add a splash of white wine to the vegetable mixture before baking.
• Use fresh herbs instead of dried for a more aromatic dish.
• If you prefer a milder cheese flavor, mix cheddar with a touch of mozzarella or Gruyère.
• Leftover fish can be flaked and added to salads or pasta for added versatility.
• Broil the gratin separately if you want a more pronounced crispy topping without overbaking the fish.

Add-ons

• Chopped fresh parsley or basil for garnish
• Drizzle of good-quality olive oil before serving
• A dollop of Greek yogurt or sour cream for added creaminess
• Roasted garlic or shallots added to the vegetable layers for extra depth

Side Dishes

• Wild rice or brown rice mixed with herbs
• Crusty French baguette or artisan bread slices
• Mixed green salad with vinaigrette
• Steamed seasonal vegetables such as asparagus or green beans

Improvements

• Use a different type of fish such as sea bass, snapper, or sea bream depending on availability.
• Add a splash of saffron or smoked paprika to the vegetable mixture for additional flavor complexity.
• Incorporate thinly sliced potatoes into the gratin layer for added texture and flavor.
• Experiment with different cheeses like Parmesan, Gruyère, or fontina for diverse flavor profiles.

Save and Store

If you have leftovers, store them in airtight containers in the refrigerator for up to 2 days. For best results, reheat in the oven at 180°C (350°F) until warmed through to preserve the crispy gratin top. Leftover fish can be flaked and used in salads or sandwiches.

FAQ

Can I prepare this dish ahead of time?

Yes. You can prepare the vegetable mixture and assemble the dish a few hours before baking. Keep covered in the refrigerator. Add the cheese topping just before baking and cook as instructed.

Can I substitute the fish with chicken or other proteins?

This dish is designed around whole fish, particularly dorade. For chicken, prepare similar layering but adjust cooking times—chicken breasts or thighs will require different baking durations and temperature adjustments to ensure they are fully cooked and tender.

Is it suitable for gluten-free diets?

Absolutely. Without breading or gluten-containing ingredients, this dish is naturally gluten-free. Just ensure that any cheeses or added ingredients are certified gluten-free.

How do I make it vegetarian?

Replace the fish with hearty vegetables such as eggplant, zucchini, or portobello mushrooms, and omit the fish altogether. Adjust cooking times accordingly.
