Ingredient substitutions:
- Cod: Any relatively firm, flaky white fish such as halibut, tilapia or flounder
- Butter: Olive oil for dairy free
- Almonds: Any other nut, such as walnuts, pecans or pistachios
- Dijon: Dijon is really the best, but in a pinch spicy brown mustard, honey dijon, honey mustard, or even mayonnaise will do. Do not use regular yellow mustard.
Other notes:
- Careful not to over-cook the fish. It will go from tender and flaky to rubbery quickly. The best way to not overcook fish is to use a meat thermometer to test the temperature. You can also tell it's ready when the flesh is opaque an flakes easily.
- Thinner fish filets will cook more quickly, so start checking at the 8-9 minute mark if you are using thin filets.
- For a simple sheet pan side dish, you can toss some frozen green beans or broccoli in olive oil and spread them on the baking sheet around the fish and bake at the same time.
- Refrigerate any leftovers for up to 4 days in an airtight container.
- This recipe is easily doubled or tripled to feed more people.
