It's hard to believe that so much flavor could come from so few ingredients! Not to mention the fact that the fish bakes in about 15 minutes. If you're looking for a delicious fish recipe for a satisfying everyday meal, this is an excellent choice.

For this recipe, mild, tasty tilapia is flavored with a Dijon mustard topping. The chopped pecans give the dish a nice crunch. To cut fat and calories, even more, use herbs in place of the pecans or use a reduced-fat mayonnaise.


  • 1 tablespoon butter (for greasing the pan)
  • 1/2 cup mayonnaise
  • 1/4 cup Dijon mustard (or similar gourmet mustard)
  • 1 pound tilapia fillets (defrost in the refrigerator if frozen)
  • 1 ounce finely chopped pecans (1/4 cup)
  • For Serving: broccoli and tomato slices

  • This is also a good choice if you're trying to lower your carb intake. And feel free to use haddock or pollock fillets in the recipe. Thicker fish fillets will take a bit longer in the oven. Serve with low carb cauliflower rice or mashed cauliflower. If you aren't lowering carbs, serve the fish with mashed or roasted potatoes.

Recipe Variation

  • Use another type of mild white fish in this recipe, such as pollock, haddock, cod, or catfish.
