Ingredient Insights and Substitutions

  • Anchovies: These melt into the sauce, bringing rich, salty umami. If anchovies intimidate you, try half the amount or substitute with finely chopped capers for a lighter briny bite.
  • Fresno chile: Adds gentle heat and color. Swap with jalapeño, red pepper flakes, or omit for a milder version.
  • Halibut: Other firm white fish (like cod or grouper) can work if halibut isn’t available or for cost reasons.
  • Olive oil: Use the best quality you have; its flavor anchors the sauce.

Step-By-Step Directions

  1. Prepare the Sauce:
    • Mix 3 tablespoons olive oil, lemon zest and juice, anchovy fillets, shallot, chile, garlic, and a pinch of kosher salt in a small bowl. Stir in chopped parsley.
    • Let the sauce sit while you cook the fish—it allows flavors to meld.

  2. Cook the Halibut:
    • Heat the remaining 2 teaspoons olive oil in a large skillet (cast-iron or nonstick) over medium-high.
    • Season halibut fillets with 1/2 teaspoon kosher salt.
    • Place the flesh side down and cook without moving until golden brown (about 4 minutes).
    • Flip carefully and cook 2–3 more minutes, until opaque throughout and fish flakes easily.
    • Transfer halibut to a platter.
  3. Finish & Serve:
    • Spoon the lemon-anchovy sauce generously over each fillet.
    • Sprinkle with extra parsley and more sliced Fresno chiles if desired.
    • Serve immediately, ideally alongside rice and roasted seasonal vegetables for a nutritious, colorful meal.

Pro Cooking Tips

  • Pat Fish Dry: Ensures the halibut browns nicely and doesn’t steam.
  • Don’t Overcook: Halibut dries out fast. Once fillets are just opaque, remove from heat immediately.
  • Use a Flexible Fish Spatula: Makes flipping delicate fillets much easier.
  • Complementary Sides: Rice pilaf, roasted spring vegetables (asparagus, carrots, broccoli), and simple green salads enhance the meal.
  • Add Capers or Tomatoes: For variations, add capers or chopped sundried tomatoes to the sauce, inspired by Mediterranean twists.
  • Garnishing: Fresh chopped parsley brings brightness and a burst of freshness to finish. Consider minced cilantro or dill for added variety.

Serving Suggestions

  • Rice or Grains: Brown rice, quinoa, or farro make hearty accompaniments.
  • Roasted Vegetables: Spring asparagus, broccoli, or carrots elevate the plate and add fiber.
  • Crusty Bread: To mop up extra sauce and juices.

Variations & Adaptations

  • Swap the Fish: Substitute other firm white fish such as cod, grouper, or swordfish for halibut.
  • Add Capers: For extra briny contrast and Mediterranean style.
  • Sundried Tomatoes: Toss in a handful for sweetness and color.
  • Grill Instead of Pan-Sear: For smoky flavor and a healthy twist.
  • Use Garlic Confit: Blends into a creamy sauce if you want less pungent garlic.
