Culinary Tips for the Best Roasted Fish

Skin on or off? For this recipe, it doesn’t matter. When you roast/bake fish in the oven with the skin side down, the skin doesn’t get crispy, so it’s not very appealing to eat. However, it does separate easily from the fish once cooked. 

Remove small pin bones before cooking using fish bone tweezers; these are no fun to bite into!

A good fishmonger at your local grocery store can help you with the pin bones and skin. Don’t be shy to ask for help!

If using a spice blend, let the spices sit on the fish for ~15 minutes before cooking for maximum flavor development.

Drizzle non-fatty fish with extra virgin olive oil to help keep the fish moist.

If using dried herbs, sprinkle on the fish before cooking, as they need to re-hydrate.

Cook the fish to an internal temperature of 145ºF for food safety.

Ingredient Substitutions

  • Fish: use any fish of your choice – barramundi, cod, halibut, salmon, tilapia, tuna, etc.
  • Spices: use any single spice or combination of spices and herbs – taco seasoning, curry powder, garam masala, ras-el hanout, Italian seasoning, etc.
  • Herbs: use any fresh herbs of your choice – basil, cilantro, dill, oregano, parsley, rosemary, thyme, etc. When choosing which herbs to use, keep in mind the flavor profile you are seeking.
  • Olive Oil: substitute avocado or canola oil.

Health Benefits of Fish

Fish is a quality source of protein that is rich in vitamins, minerals, and sometimes healthy fats. The American Heart Association recommends eating two, 3.5-ounce servings of fish per week, and the Dietary Guidelines for Americans recommend 8 total ounces per week for the general population.

What Types of Fish are Considered Fatty?

Salmon, albacore tuna, herring, and mackerel are examples of fatty fish. Non-fatty fish examples include cod, halibut, barramundi, mahi mahi, pollock, and tilapia. Fatty fishes are especially high in EPA and DHA omega-3 fatty acids, which are good for heart and brain health. Non-fatty fish provides lean protein – a great way to reduce total saturated fat in the diet.

Serving Suggestions

Serve roasted fish as the main protein for wraps, bowls, or salads. Or create a plant-forward plate by serving alongside roasted vegetables and a whole grain such as brown ricequinoa, or farro.
