I’ve been home from France for a few weeks now, and I’m still thinking about the fresh fish served with sauce vierge we had in Cannes. It was the kind of meal that quietly rearranges the way you think about food.
We were seated at a casual chic beachside restaurant. Nothing fussy yet everything intentional. The frame worthy watercolor menu had me at hello. Although it was short, it lacked nothing. Seasonal, fresh, and infused with quality ingredients. Calling to us was the local grilled fish. They brought out a whole fish, filleted tableside with the kind of unhurried confidence that the French seem to have about everything. It was stunning. But here’s the thing… what I couldn’t stop thinking about wasn’t the fish at all.

It was the sauce.
A sauce vierge. This shining star is a simple, no-cook sauce served at room temperature — and of course I had to ask our waiter a few questions about it (we’d become fast friends over the tableside fish filet session). Chopped tomatoes, fresh herbs, garlic, capers, a pour of really good olive oil, and a squeeze of lemon. That’s it. And yet somehow it tasted like summer and sunshine and every good thing about being alive in the south of France.

That’s the thing about French cooking that keeps catching me off guard — it’s not complicated. It’s just intentional. Quality ingredients, treated with respect, served simply. The French don’t dress up mediocre tomatoes and call it a day. Oh no… they wait for the good ones, use olive oil they actually love, and don’t overthink it.

I’ve been recreating this dish at home ever since, and it has become one of my most-reached-for recipes. Slightly flour dusted red snapper, pan-seared until golden, topped with a generous spoonful of that herb-loaded, bright, glossy sauce. It looks gorgeous on the table. It comes together in 20 minutes. And every single time I make it, I’m back in that restaurant, watching a fish get filleted tableside and asking my waiter for a grocery list.
This one is for your weeknight table and your dinner party gathering alike. The kind of recipe that makes people think you’ve been to culinary school, when really, you’ve just been to France.

A Few Notes Before You Cook
On the sauce vierge: Make it first, even an hour or two ahead if you can. The flavors deepen as it sits, and serving it at room temperature over warm fish is part of what makes it so good. It also keeps beautifully overnight. Don’t just save it for fish, spoon it over chicken, roasted vegetables, or toss it into pasta. It’s one of those sauces that makes everything better, like my What’s in my Fridge Frittata.
On the herbs: Use what you love and what looks good at the market. Chives, tarragon, parsley, and basil are all wonderful here, individually or in combination. Tarragon is particularly French and particularly good if you can find it. This affordable chef’s knife is my kitchen workhorse and perfect for chopping your herbs.
On the fish: Red snapper is my first choice, but yellowtail or grouper work beautifully too. What matters most is that the fish is fresh and the fillets are patted completely dry before they hit the hot pan — this is what gives you that golden, crispy crust.
On the flour: A light dusting of flour (I use Bob’s Gluten Free 1-to-1) helps the skin crisp up and turn golden. You can skip it as the fish will still be delicious but it won’t have quite the same dramatic crust.

Other Ways to Use Sauce Vierge
Once you make a batch of this sauce, you’ll find yourself reaching for it all week. A few of my favorite ways to use it beyond fish:
- Over omelettes or a frittata: spoon it on warm right before serving for a breakfast or brunch that feels like it belongs on a café menu
- As a dip with corn chips or crostini: the capers and herbs give it enough body to hold up beautifully, and it disappears fast at a party
- Bruschetta: pile it onto grilled or toasted bread for the easiest, most impressive appetizer you’ll make all summer
- Over chicken or roasted vegetables: it transforms a simple weeknight dinner into something that feels intentional
- Tossed into pasta: warm the pasta, spoon the sauce over, and let the heat do the work
Make a double batch. You’ll thank yourself.

Pan Seared Red Snapper with Sauce Vierge
Ingredients
Sauce Vierge
- 2 cups grape or cherry tomatoes chopped
- 1 medium shallot diced
- ½ cup finely chopped fresh herbs any combination of chives, tarragon, parsley, basil
- 2 garlic cloves smashed
- juice of 1 lemon
- 2 tablespoons capers
- kosher salt and freshly ground black pepper
- 1 cup extra virgin olive oil
Fish
- 16 ounces red snapper filets (about 4 filets) or yellowtail or grouper
- 1 tablespoon flour Bob's Gluten Free 1 to 1 works well
- kosher salt and freshly ground black pepper
- 1 tablespoon olive oil
- 2 tablespoons unsalted butter divided
- fresh lemons juice for finishing
- flaky sea salt for finishing
Instructions
Sauce Vierge
- Combine all sauce ingredients in a medium bowl and toss to combine. Taste for seasoning and adjust. Serve at room temperature over fish, chicken, or roasted veggies. Toss into pasta or serve as a dip for toasted bread.
- Use immediately, or the next day. Keep in an airtight container and allow to come to room temperature before serving.
Fish
- Pat snapper fillets dry. Dust with flour, and shake off any excess. Sprinkle them on both sides with salt.
- Heat a heavy bottom skillet along with olive oil and 1 tablespoon butter on medium-high until butter is melted but not browned, then turn the heat down to medium.
- Place the fillets in the pan and cook 3-4 minutes. Don't touch the fillets until they're ready to flip.Use a thin metal spatula to test the fish. If you can slide the spatula under the fish without the fish sticking to the pan, it's ready to flip. If the fillets won't release, give them another 30 seconds. They'll release when they've finished cooking.
- Cook fish another 3-4 minutes until done. Fish will be golden on both the top and bottom and opaque all the way through when finished cooking.Transfer the fish to a plate, pouring any excess butter from the pan, over the filets. Season with a few grinds of freshly cracked pepper, a squeeze of lemon, and sprinkle of flaky sea salt. Divide remaining butter over tops of warm filets and allow it to melt into the fish. Serve with sauce vierge for an epic flavor combination.
