- 3 tablespoons extra virgin olive oil
- 4 garlic cloves, finely minced
- 1 lemon, half sliced and half juiced
- 1 teaspoon sea salt
- ½ teaspoon freshly ground black pepper
- 1 teaspoon paprika
- 1 teaspoon dried oregano
- 4–5 fresh thyme sprigs
- 2 tablespoons chopped fresh parsley
For the Roasted Vegetables

- ½ teaspoon salt
- ¼ teaspoon black pepper
- ½ teaspoon dried thyme

How to Make Oven-Baked Dorado with Potatoes and Tomatoes
Step 1: Prepare the Fish
Preheat your oven to 425°F.
Rinse the cleaned dorado if needed and pat it completely dry with paper towels.
Using a sharp knife, make several diagonal cuts across both sides of each fish. These cuts help the seasoning penetrate the flesh and allow the fish to cook more evenly.
In a small bowl, combine olive oil, minced garlic, lemon juice, salt, black pepper, paprika, and oregano.
Rub the mixture all over the fish, including inside the cavity and between the cuts.
Stuff each fish with a few lemon slices, fresh thyme, and a little parsley.
Set aside while you prepare the vegetables.
Step 2: Prepare the Potatoes and Tomatoes
Place the halved baby potatoes in a large bowl.
Add olive oil, salt, black pepper, paprika, and dried thyme. Toss until the potatoes are evenly coated.
Spread them in a large baking dish or on a rimmed baking sheet.
Roast for approximately 15–20 minutes, until they begin to soften and develop golden edges.
Step 3: Add the Tomatoes and Garlic
Remove the baking dish from the oven.
Add the cherry tomatoes and garlic cloves around the potatoes.
Drizzle with a little additional olive oil and gently toss the vegetables without crushing the tomatoes.
Arrange the seasoned dorado in the center of the baking dish, making sure the fish has enough space to roast evenly.
Step 4: Bake the Dorado
Return the baking dish to the oven.
Bake at 425°F for approximately 20–25 minutes, depending on the size and thickness of the fish.
The potatoes should be tender, the tomatoes slightly blistered, and the fish should flake easily with a fork.
For food safety, check the thickest part of the fish with an instant-read thermometer. It should reach 145°F.
Step 5: Garnish and Serve
Remove the baking dish from the oven and let the fish rest for a few minutes.
Sprinkle with fresh parsley, add a squeeze of lemon juice, and spoon some of the flavorful olive oil and roasted tomato juices over the fish.
Serve immediately with the golden potatoes, roasted tomatoes, and soft garlic cloves.
Tips for the Best Oven-Baked Dorado
Dry the fish before seasoning. Removing excess moisture helps the skin roast more beautifully.
Don’t skip the diagonal cuts. They help distribute the garlic, herbs, and seasoning throughout the fish.
Give the potatoes a head start. Potatoes generally need longer to cook than fish, so roasting them first helps everything finish at approximately the same time.
Use fresh garlic and lemon. They bring brightness and depth to the Mediterranean flavors.
Avoid overcooking the fish. Dorado is naturally delicate, and cooking it too long can make the flesh dry.
Easy Variations
- Add Mediterranean vegetables: Zucchini, red onions, and bell peppers make excellent additions.
- Make it spicy: Add a pinch of red pepper flakes or cayenne pepper to the olive oil mixture.
- Use fresh rosemary: Replace some of the thyme with rosemary for a deeper herbal flavor.
- Add olives: A handful of Kalamata olives adds a delicious salty Mediterranean touch.
- Try different fish: Whole sea bass or branzino can also work beautifully with this preparation. Adjust cooking time according to the size and thickness.
What to Serve with Baked Dorado
This dish is already a complete meal, but a few simple sides can make it even better.
- A fresh cucumber and tomato salad
- Warm crusty bread for soaking up the garlic and olive oil juices
- Mediterranean couscous
- Steamed green beans with lemon
- A simple arugula salad with lemon vinaigrette
Frequently Asked Questions
What is dorado fish called in the United States?
Dorado can refer to different fish depending on the region. The fish commonly used in Mediterranean recipes is often called gilthead sea bream or simply sea bream in English. It is not the same as mahi-mahi, which is also sometimes called dorado in Spanish-speaking regions.
Can I use frozen dorado?
Yes. Thaw the fish completely in the refrigerator before cooking. Pat it dry thoroughly before adding the seasoning.
Can I use fish fillets instead of whole fish?
Absolutely. Sea bream fillets work well, but they cook much faster than whole fish. Add them after the potatoes have roasted and adjust the cooking time according to their thickness.
How do I know when dorado is cooked?
The flesh should be opaque and separate easily with a fork. For a reliable food-safety check, the thickest part should reach 145°F.
Can I prepare this recipe ahead of time?
You can clean and season the fish, prepare the potatoes, and mix the garlic and herbs a few hours ahead. Keep everything refrigerated until you’re ready to cook.
How do I store leftovers?
Remove the fish flesh from the bones and store it with the vegetables in an airtight container in the refrigerator for up to 2 days. Reheat gently until thoroughly hot.
