  • 1 cup Pecans
  • 4 pieces White fish haddock, cod, flounder
  • Salt and pepper to taste
  • 2 TBS Honey mustard
  • ¼ cup Parmesan cheese grated
  • Olive oil for drizzling


  • Preheat oven to 350. Place pecans on baking sheet, and toast 7-8 minutes, stirring occasionally, until fragrant and slightly golden. Remove and set aside.
  • Line a baking sheet with aluminum foil and place cooling rack on top; spray with non-stick cooking spray. (The cooling rack will help to circulate even air flow for a crispier crust).
  • Place toasted pecans and Parmesan cheese in food processor and pulse until nicely ground. Dump onto a shallow bowl or plate.
  • Sprinkle both sides of fish with salt and pepper and brush both sides with a layer of honey mustard.
  • Place fish in pecan crumbs and coat all sides. Place on cooling rack-lined baking sheet.
  • Repeat for all 4 pieces of fish. Drizzle tops of fish with olive oil.
  • Bake at 350 for 20-25 minutes. The fish should flake when you cut into it with your fork.


*If you don’t have a food processor, simply add pecans to Ziploc bag and crush with bottom of cup, fist, or meat tenderizer until you have fine crumbs.
