I took classic chimichurri and gave it a Mediterranean twist—green olives, capers, and fresh lemon juice bring a bright, savory edge. It’s especially lovely spooned over pan-seared white fish for a quick, elegant weeknight dinner.
Pan Seared Fish with Olive Chimichurri
I’ve always loved chimichurri, but I hadn’t tried it with olives and lemon until I tasted it with branzino at a restaurant. The combination of briny olives and capers, fresh parsley, garlic, and lemon juice makes a bright, layered sauce that pairs beautifully with simple pan-seared white fish. The fish gets a golden crust while remaining tender inside; the chimichurri adds acidity and umami that lift the whole dish. It’s an excellent meat-free option for Lent, fits a Mediterranean-style diet, and is easy enough for a weekly rotation.
Why This Pan Seared Fish Recipe Works
Chimichurri is traditionally a South American herb-and-oil sauce. By adding chopped olives and capers and swapping red wine vinegar for fresh lemon juice, the sauce becomes brighter and more Mediterranean. The acidity from the lemon balances the saltiness of the olives and capers, while fresh parsley and garlic keep the flavor clean and herbaceous. The result is a vibrant sauce that complements delicate white fish without overpowering it.
- Lenten friendly: A satisfying meat-free dinner option.
- Mediterranean diet: Uses olive oil, herbs, lemons, and fish—classic components of a Mediterranean-style meal.
- High protein: Fish is a lean source of protein; one serving delivers a substantial amount.
- Quick and easy: The chimichurri comes together in just a few minutes by hand, and the fish sears in under 10 minutes.
- Allergy-friendly: Naturally gluten-free and dairy-free; suitable for many dietary plans.

What You’ll Need
Below are the ingredients and basic equipment you’ll want on hand for pan-seared fish with olive chimichurri. Exact ingredient amounts appear in the recipe card further down.
- Base: Fresh lemon juice and extra-virgin olive oil form the sauce.
- Aromatics: Red onion and plenty of garlic give the chimichurri depth.
- Briny elements: Green olives and capers add tang and umami—choose manzanilla or Castelvetrano-style olives if you like a milder flavor.
- Seasoning: Kosher salt, black pepper, and a touch of crushed red pepper for heat.
- Herbs: Fresh parsley and a pinch of dried oregano for earthiness.
- White fish fillets: Branzino, red snapper, halibut, cod, or other firm white fish work well.
- Pantry items for cooking: A little olive oil to sear the fillets and a sharp skillet that conducts heat evenly.
How to Pan Sear Fish
This recipe is low effort for a big payoff. Make the chimichurri first—no food processor required—then sear the fish until golden. The whole process takes about 25 minutes from start to finish.
- Make the chimichurri: Finely chop olives, capers, red onion, parsley, and garlic. Stir together with lemon juice, olive oil, oregano, salt, pepper, and crushed red pepper. Taste and adjust acidity or salt as needed.
- Season the fish: Pat fillets dry, then season with kosher salt and black pepper to taste.
- Sear the fish: Heat a tablespoon of olive oil in a large skillet over medium-high heat. Place fillets skin-side down and cook until the edges begin to brown and the skin is crisp—about 4–5 minutes. Flip carefully and cook an additional 3–4 minutes until the fish flakes easily with a fork and is opaque through the center.
- Serve: Spoon about two tablespoons of chimichurri over each fillet and serve with lemon slices.
Variations
- Swap the acid: If you prefer, use red or white wine vinegar instead of lemon juice for a different tang.
- No olives: Omit the olives for a more classic chimichurri while keeping the capers for a hint of brine.
- Different fish: Any fresh white fish will work—choose what’s in season or locally available.
How do you get the bitterness out of chimichurri?
To avoid bitterness, use fresh flat-leaf parsley and discard any thick, fibrous stems. Finely chopping the herbs and other ingredients by hand helps control texture and release flavor more gently than a food processor, which can sometimes make herbs taste bitter.
Serving Suggestions for Pan Seared Fish
This fish is versatile—pair it with light salads or roasted vegetables, or serve alongside a starchy side for a more substantial meal. Some ideas:
- Salads: Arugula salad or a chopped feta salad for bright, leafy contrast.
- Veggies: Roasted asparagus, sautéed greens, or air-fried radishes.
- Starchy sides: Lemon-parsley potatoes, a light orzo salad, lentil salad, or a chickpea salad.
Storage
- Make ahead: You can prepare the chimichurri up to one day in advance to let the flavors meld.
- Refrigeration: Store both the cooked fish and sauce in airtight containers in the refrigerator for up to 3 days.
- Bring to room temperature: If the chimichurri has been chilled, let it sit at room temperature briefly before serving so the oil isn’t too firm and the flavors are pronounced.
