Provençale Chilean Sea Bass Recipe With Pesto

This Mediterranean-inspired Chilean sea bass topped with pesto and sundried tomatoes creates an elegant dinner that's surprisingly simple to master.

The Simple Joy of this Provençale Chilean Sea Bass with Pesto

Three simple ingredients can transform your weeknight dinner from mundane to magnificent, and this Provençale Chilean Sea Bass proves that point beautifully. I’m talking about sundried tomatoes, pesto, and mayonnaise. That’s it. No fancy knife skills required, no complicated techniques that’ll leave you questioning your life choices. Just mix, top, and bake. The pesto brings herbaceous brightness, while those sundried tomatoes add concentrated umami punch. The mayo? It keeps everything moist and helps create this gorgeous golden crust. Sometimes I wonder why I overcomplicate things when simple combinations like this deliver restaurant-quality results without the stress.

Ingredients

Getting your hands on the right ingredients for this Provençale Chilean Sea Bass is honestly half the battle won. You’re looking at a pretty straightforward shopping list here, nothing too exotic or wallet-draining. The star of the show is obviously that beautiful Chilean sea bass, and while it might cost a bit more than your usual fish selection, trust me when I say it’s worth every penny for its buttery texture and mild flavor.

  • 16 ounces Chilean sea bass
  • 6 sundried tomatoes, chopped
  • 1 green onion, chopped
  • 1/4 cup pesto sauce
  • 3 tablespoons mayonnaise
  • 2 tablespoons olive oil
  • Salt and pepper to taste

Now, let’s talk about a few ingredient swaps and considerations that might save your dinner plans. If Chilean sea bass is nowhere to be found or your budget is giving you the side-eye, halibut or cod work beautifully as substitutes.

For the pesto, you can absolutely use store-bought, but if you’ve got fresh basil hanging around, homemade pesto takes this dish to another level. Those sundried tomatoes packed in oil will give you more flavor than the dried ones, plus you can use some of that oil for extra Mediterranean goodness.

And here’s a little secret, if you’re out of mayo, Greek yogurt works as a lighter substitute, though you’ll miss out on some of that golden browning magic.

How to Make this Provençale Chilean Sea Bass with Pesto

Getting this gorgeous dish together is surprisingly simple, and I mean that in the best possible way. First things first, crank your oven to 375 degrees F because nobody wants to wait around with hungry people staring at raw fish.

While that’s heating up, grab a large bowl and toss together your 6 chopped sundried tomatoes, 1 chopped green onion, 1/4 cup pesto sauce, 3 tablespoons mayonnaise, and 2 tablespoons olive oil. This mixture is going to be your flavor bomb topping, so give it a good stir until everything’s nicely combined and looking like the Mediterranean decided to have a party in your bowl.

Now for the easy part that somehow always makes me feel like a real chef. Drizzle a light coating of olive oil on your baking sheet, just enough so your beautiful 16 ounces of Chilean sea bass won’t stage a sticking rebellion.

Place that gorgeous fish right on the sheet, then generously spread your tomato-pesto mixture on top like you’re frosting the world’s most expensive cake. Don’t be shy with the salt and pepper here, fish needs seasoning love just like everything else.

Slide that baby into your preheated oven for 12 to 15 minutes, but here’s the thing, ovens are liars sometimes, so your best bet is checking that internal temperature hits 145 degrees F with a meat thermometer.

The fish should flake easily when it’s done, and that topping will be slightly golden and smelling like you’ve transported your kitchen straight to the French countryside. For making larger batches or preparing sides, having a professional soup pot makes whipping up accompanying sauces or broths much easier.

Substitutions and Variations

While this recipe is pretty fantastic as written, I totally get that sometimes you’re standing in your kitchen staring at half the ingredients and wondering if you can make it work anyway.

Don’t have Chilean sea bass? Halibut or cod work beautifully.

Out of pesto? Mix basil, garlic, pine nuts, and olive oil.

No sundried tomatoes? Cherry tomatoes, chopped fine, add lovely sweetness.

Greek yogurt can replace mayonnaise for tang.

Green onions missing? Regular onions or shallots work.

Even the fish itself is flexible – salmon transforms this into something completely different but equally delicious.

Additional Things to Serve With Provençale Chilean Sea Bass with Pesto

The Mediterranean flavors in this dish practically beg for companions that won’t compete but will complement that gorgeous pesto-tomato topping.

I’d reach for crispy roasted potatoes with garlic and herbs, or maybe some buttery rice pilaf. A simple arugula salad with lemon vinaigrette cuts through the richness nicely.

Grilled asparagus or zucchini work beautifully too. For bread lovers like myself, warm crusty sourdough is perfect for sopping up those incredible pan juices.

And here’s my secret weapon: a light white wine like Sauvignon Blanc or Pinot Grigio ties everything together without overwhelming that delicate fish.

Final Thoughts

Looking at this Provençale Chilean Sea Bass recipe, I can’t help but think about how cooking doesn’t always have to be complicated to be absolutely stunning.

Sometimes the best dishes come from simple combinations that just work together beautifully. The pesto, sundried tomatoes, and fresh herbs create this Mediterranean magic that transforms basic fish into something special.

What I love most is how forgiving this recipe is – you can adjust the pesto amount, add more tomatoes, whatever suits your taste.

It’s the kind of dish that makes you feel like a fancy chef without breaking a sweat.
