Tips for Choosing and Cooking Pan Seared Fish

  • Fresh white fish should have a somewhat translucent appearance. Solid white may indicate not-so-fresh fish.
  • Fish should be firm to the touch and wet, not dry or sticky.
  • Fish should be labeled, or the fishmonger can tell you, if it has been previously frozen (not a bad thing).
  • If fish was frozen after being caught, buy it frozen, then thaw slowly at home.
  • Grouper can be substituted in this recipe with any firm, white fish. Cod, haddock, flounder, tilapia, branzino, etc.
  • Use a fish spatula, such as this one, when flipping delicate fish to keep it in one piece.

Servings 4


  • 4 6 oz. grouper fillets
  • 2 TB extra virgin olive oil
  • 6 TB unsalted butter, cut into chunks
  • 2 TB lime juice
  • 2 TB fresh parsley leaves, finely chopped


  • Heat olive oil in a large skillet over medium heat. Generously sprinkle the grouper fillets with salt and black pepper on both sides and cook until opaque and flaky, approximately 3-4 minutes per side. Remove from heat and cover to keep warm.
  • Add the butter to a small skillet set over medium heat, whisking continually until the butter melts and darkens in color, approximately 3 minutes.
  • Remove from heat and whisk in the fresh lime juice. Stir in the fresh parsley leaves and season with salt and black pepper, to taste.
  • Serve the grouper fillets immediately with a drizzle of the lime butter sauce on top. Pair with our Garlic Mashed Red Potatoes and Oven-Roasted Asparagus, as pictured, or your choice of sides. Enjoy!
