Ingredients

  • 8.8 oz Cod fish fillets
  • 1/4 cup walnuts
  • 2 tablespoons butter melted
  • 3 tablespoons parmesan cheese
  • 1 teaspoon garlic powder
  • 1 teaspoon dried parsley
  • 1 teaspoon dried dill
  • 1 teaspoon lemon zest
  • 1/4 teaspoon salt
  • 1/8 teaspoon black pepper
US Customary - Metric

Instructions

  • Preheat your oven to 360°F (180°C) and lightly grease a baking dish with olive oil or cooking spray.
  • Place the walnuts in a food processor and pulse until coarsely ground. You can also chop them by hand for a chunkier texture. In a bowl, mix the ground walnuts with melted butter, parmesan cheese, garlic powder, parsley, dill, lemon zest, salt, and black pepper. The mixture should be crumbly and stick together when pressed.
  • Pat the cod fillets dry with a paper towel to remove excess moisture. Place the fillets in the prepared baking dish, making sure they are evenly spaced.
  • Top with the walnut mixture: Spoon the walnut crust mixture over the top of each cod fillet. Gently press it down so it adheres to the fish.
  • Bake for 15-20 minutes, or until the cod flakes easily with a fork and the crust is golden brown. For optimal doneness, the internal temperature of the fish should reach 145°F (63°C).
  • Garnish with fresh lemon wedges and serve with your favorite keto-friendly sides, like cauliflower rice or roasted vegetables.

Notes

  • Walnut texture: Keep walnuts coarsely ground for a crispy crust.
  • Fish options: Use halibut, haddock, or pollock as substitutes.
  • Nut-free: Swap walnuts for crushed pork rinds or pumpkin seeds.
  • Make ahead: Prepare the walnut crust up to 3 days in advance.
  • Storage: Leftovers keep for 3 days in the fridge. Reheat in the oven or air fryer at 350°F to maintain the crispy texture.
