Baked Sea Bream with Potatoes: Spanish Oven Classic 2026

Baked sea bream with potatoes is one of the most straightforward ways to cook this rich, flavorful blue fish. A whole bream is scored, tucked with lemon slices and roasted over a bed of onion and par-boiled potatoes, so the juices soak into the vegetables as it cooks.

Cherry tomatoes and a splash of fish stock round out the tray, giving you a complete main course in under an hour. The fish stays moist and juicy while the potatoes turn tender and golden at the edges.

Ingredients for Baked Sea Bream with Potatoes

For 4 servings

• 1 sea bream (about 1 kg)
• 3 medium potatoes
• 1 onion
• 50 g cherry tomatoes
• 50 ml olive oil
• Salt
• 30 ml fish stock
• 1 lemon

How to Make Baked Sea Bream with Potatoes Step by Step

1. Score the fish

Ask the fishmonger to clean the whole fish, specifying that it is for oven baking. Once you have the cleaned fish at home, make a few crosswise cuts along the back so you can tuck pieces of lemon into them. Turn the oven on to 220 °C with top and bottom heat.

2. Prep the vegetables

Peel 3 medium potatoes and cut them into slices about half a centimeter thick. Peel and cut 1 onion into thin slices, then wash and halve 50 g of cherry tomatoes.

3. Par-boil the potatoes

Put the sliced potatoes in a pot, cover them with cold water and boil them for 10 minutes, since they will finish cooking in the oven. After this time, drain them well.

4. Build the bed and add the fish

Grease a roasting dish with 30 ml of olive oil and lay down a bed of onion. On top of that, add the previously boiled and drained potatoes and season them with salt. Salt the sea bream on both sides too and place it over the onion and potato bed.

5. Add oil, stock, lemon and tomatoes

Add the remaining 20 ml of olive oil and 30 ml of fish stock, then place a few lemon slices into the cuts you made along the fish's back. Scatter the halved cherry tomatoes around the dish.

6. Bake and check doneness

Bake the fish for about 20-30 minutes, depending on its size. After the first 20 minutes, check whether the fish is cooked and juicy. Since cooking time varies with the size of the fish, it is always best to check the doneness. Once the fish is at its optimal point, take it out of the oven.

7. Serve with its garnish

Serve the sea bream in portions accompanied by the potatoes and some cherry tomatoes.

Tips for the Best Baked Sea Bream with Potatoes

Watch the cooking point

For a perfect result, it is important to hit the ideal cooking point for both the garnish and the fish. Sea bream is a very juicy fish, but if it is overcooked its flesh will dry out.

Par-boil the potatoes first

The cooking times for the fish and the potatoes are not the same, so you cannot cook potatoes and fish together in the oven from raw, since the potatoes need a little more time to be just right. To keep them from coming out undercooked, boil them briefly before they go into the oven.

Check the fish as it bakes

Because the fish varies in size, check it after the first 20 minutes of baking to see if it is done and still juicy. Pull it from the oven as soon as it reaches its optimal point rather than relying strictly on the clock.
