Introduction

This Cod & Cherry Tomato Bake is a light, flavorful dish perfect for a healthy weeknight dinner. With juicy cherry tomatoes, aromatic basil, and tender cod, it combines fresh ingredients into a simple, satisfying meal.

Two white plates each have a dish with three layers: the bottom layer is fresh green beans, the middle layer is a piece of white grilled fish, and the top layer is bright red roasted cherry tomatoes with some dark purple olives, all lightly drizzled with sauce. The dishes are set on a patterned blue and white tiled surface with a small white bowl containing crushed black pepper on the top left and a white bowl of yellow whole and sliced finger potatoes on the right bottom corner. The colors are vibrant and the textures show the softness of the fish, the crispness of the beans, and the juiciness of the tomatoes. photo taken with an iphone --ar 4:5 --v 7

Ingredients

200g vine cherry tomatoes, halved
3 tbsp finely chopped basil leaves
6 Kalamata olives, halved
1 garlic clove, finely grated
1 tbsp olive oil
2 cod loins, about 130g each
300g new potatoes, halved
180g fine green beans, ends trimmed
1 tbsp extra virgin olive oil
1 tbsp balsamic vinegar

Instructions

Step 1: Preheat the oven to 200°C (180°C fan) or gas mark 6. In a small non-stick roasting tin or shallow ovenproof dish, toss the halved cherry tomatoes with 2 tablespoons of the chopped basil, Kalamata olives, grated garlic, and 1 tablespoon of olive oil.
Step 2: Add the cod loins to the dish and bake in the oven for 15–18 minutes, until the cod is cooked through and flakes easily.
Step 3: While the cod cooks, boil the halved new potatoes in a pan with a steamer set over the top. Place the trimmed green beans in the steamer and cook both potatoes and beans for about 15 minutes until tender.
Step 4: Arrange the cooked green beans in the center of two dinner plates and place the baked cod on top.
Step 5: Tip the roasted tomatoes and their juices into a bowl. Add the remaining tablespoon of chopped basil, extra virgin olive oil, and balsamic vinegar, then mix gently.
Step 6: Spoon the tomato mixture over the cod and serve the potatoes on the side. Optionally, sprinkle with cracked black pepper before serving.

Tips & Variations

Substitute green beans with asparagus or broccoli for a different vegetable option.
For a spicier kick, add a pinch of chili flakes to the tomato mixture before baking.
If Kalamata olives aren’t available, green olives or capers also work well in this dish.
Use fresh cod loins for the best texture, or frozen if fresh isn’t accessible—just ensure to thaw completely before cooking.

Storage

Store any leftovers in an airtight container in the refrigerator for up to two days. To reheat, warm gently in the oven at 160°C until just heated through to avoid drying out the cod. Avoid microwaving if possible, as it can make the fish rubbery.

How to Serve

Two white plates each have a layered dish with green beans as the bottom layer, topped with a white cooked fish fillet, then roasted red cherry tomatoes along with a few dark purple olives on top. The fish has light grill marks and some black pepper sprinkled on it. To the side, there is a white bowl with crushed black pepper and another white bowl filled with yellow roasted potato wedges on a white marbled surface with blue and white patterned tiles in the background. The colors are bright with a contrast between the green, red, white, and yellow photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use other types of fish instead of cod?

Yes, firm white fish like haddock, halibut, or pollock would work well in this recipe as they hold their shape during baking.

Is it possible to prepare this dish ahead of time?

You can prepare the tomato mixture and chop the vegetables in advance, but it’s best to bake the cod and cook the vegetables just before serving to maintain freshness and texture.
