Easy Step-by-Step Instructions

  1. Cook the Quinoa:
    • Rinse the quinoa well if needed to remove bitterness.
    • Prepare according to package directions (typically combine with double the amount of water; bring to a boil; reduce heat and simmer covered for 12–15 minutes until water is absorbed).
  2. Preheat the Oven:
    • Set oven to 375°F (190°C). Line a rimmed baking sheet with nonstick foil for easy cleanup and spray lightly with cooking spray.
  3. Prepare and Season Fish:
    • Pat fillets dry with a paper towel to ensure proper crust adhesion.
    • Sprinkle both sides with 1/2 teaspoon salt and 1/4 teaspoon black pepper.
    • Brush the top of each fillet with approximately 1 tablespoon of Greek yogurt.
  4. Mix the Pistachio Crust:
    • In a bowl, combine 1/4 cup finely chopped pistachios and 1/4 cup whole-wheat panko breadcrumbs.
    • Add 1 tablespoon olive oil and stir to evenly moisten the mixture.
  5. Crust and Bake Fish:
    • Evenly sprinkle the pistachio-panko mix over each fillet and gently press to adhere.
    • Place the crusted fillets on the prepared baking sheet.
    • Bake 12–15 minutes, until fish is opaque and flakes easily with a fork.
  6. Prepare Spinach Quinoa:
    • When quinoa is cooked, fluff with a fork.
    • Add 4 cups fresh baby spinach, 2 tablespoons lemon juice, remaining 1 tablespoon olive oil, and 1/4 teaspoon each of salt and pepper.
    • Toss while quinoa is hot, wilting the spinach slightly and combining flavors.

Chef’s Tips and Variations

  • Fish Options: Cod and tilapia are excellent, but any firm white fish (such as haddock, grouper, or halibut) will work.
  • Panko Substitutes: For a gluten-free version, use GF panko or crushed rice crackers.
  • Nut-Free Option: Replace pistachios with toasted seeds (such as pumpkin seeds or sunflower seeds) if allergies are a concern.
  • Dairy-Free: Use a non-dairy Greek-style yogurt alternative.
  • Add Extras: Mix fresh herbs (dill, parsley) or lemon zest into the quinoa for extra brightness.

Expert Tips for Perfect Pistachio-Crusted Fish

  • Preventing Fishy Odor: Rinse fillets in cold water and, if sensitive to odor, soak briefly in milk to neutralize smells before patting dry.
  • Baking Check: Look for fish to be opaque throughout and flake easily with a fork. For extra precision, a food thermometer should read 145°F in the thickest part.

A: Firm white fish like cod, tilapia, haddock, or halibut works well. Salmon is also delicious with a pistachio crust.

A: Yes. You can make the quinoa ahead, and the pistachio-panko blend can be prepped a day early. Assemble and bake the fish just before serving for crispness.
