Branzino with Sauce Vierge

Branzino with Sauce Vierge is a great way to introduce yourself to cooking fresh fish. This recipe is made with fresh Branzino seasoned with garlic, salt, and pepper and roasted to perfection and served with the Sauce Vierge – a bright and tangy, offsetting the richness of the Branzino.
This roasted Branzino with Sauce Vierge is perfect for Sunday dinner. It’s light, delicious, and also very easy to make. And it’s not only suitable for dinner since this recipe can also be served as lunch.
What is Branzino
The Branzino is a firm, white fish commonly used in Mediterranean cuisine. Its mild, slightly sweet-tasting flesh makes it highly prized for fine dining as well as for home cooking. It pairs perfectly with our Sauce Vierge recipe. The sauce, which is made from an assortment of fresh tomatoes, herbs, and extra virgin olive oil, tastes great drizzled over the fish or potatoes.

What is Sauce Vierge
From our preview blog post, it’s a vinaigrette made with just chopped tomatoes, olive oil, and fresh herbs, along with a splash of lemon juice and zest. The ingredients are tossed together before being served and can be used to dress grilled meat or fish.
Sauce Vierge is a quick and easy way to add some flavor to your food. It’s great on sandwiches, salads, and even grilled chicken. It was created and popularized by the great French chef Michel Guérard and is a famous example of his cuisine minceur, a lighter spin on traditional nouvelle cuisine.

The ingredients for Branzino with Sauce Vierge
I’m a fan of simple recipes. There’s no better time to cook something plain, with few ingredients, than when you’re tired and hungry in the evening. This recipe is great because not only is it fast, healthy, and flavorful, but it’s also extremely easy to make. Here is what you need:
For the Branzino
- Whole Branzino (2) scaled and gutted: if you can buy fresh whole fish.
- Extra-virgin olive oil: always the best brand
- Kosher or Sea salt and freshly ground pepper: to season the fish
- Garlic Cloves: fresh whole garlic to add freshness
- Lemon
- Small bunch of thyme and parsley sprigs

For the Sauce Vierge
Tomatoes: peeled, cored, and diced. You can use either Campari, Heirloom, Roma, Cherry, or Grape tomatoes.
Vinegar of your choice: rice wine vinegar, champagne vinegar, balsamic or white wine vinegar
Shallots, minced: red onion or regular white onion.
Extra Virgin Olive Oil: this is the best oil you should use for this recipe. You can also use a lemon-infused oil or any other citrusy-infused olive oil.
Sea salt: Himalayan or Fleur du Sel is also great. Make sure that the salt is acceptable so it can resolve quickly.
Ground Black Pepper: fresh is always better.
Fresh herbs: always use fresh herbs. Your options are parsley, basil, chives, tarragon, and my watercress. Although watercress is a leafy vegetable that is mostly in salads and stews, its slightly bitter and peppery taste goes wonderfully with lemon juice and olive oil.
Fresh lemon juice: is also a must. Do not substitute with bottled lemon juice. It won’t have the same fresh taste.
Lemon zest: this adds a fresh lemon taste that goes well with fresh tomatoes and olive oil.
How to make the recipe Branzino with Sauce Vierge
Prepare the fish for roasting. Clean, scale, and gut, rinse with water, and pat dry. The fish is then seasoned with oil, salt, and pepper. The cavity is stuffed with fresh herbs, garlic slices, and lemon slices. Roast at 425 degrees Fahrenheit for 25-30 minutes. (cooking time may be slightly less or more depending on the size of the fish.)
The Sauce Vierge is prepared by mixing all the ingredients and served with the roasted Branzino.
