For the best results, use fresh bluefish fillets with the skin removed. You can find these at most seafood counters or high-quality fish markets. If you’re concerned about the strong flavor of bluefish, try soaking the fillets in milk for 30 minutes before baking. The mayonnaise sauce is what keeps the fish moist, so don’t skimp on the full-fat mayonnaise.

No fresh dill? You can substitute with dried dill weed at one-third the amount called for. If you prefer a lighter coating, you can reduce the mayonnaise to 3/4 cup. For an extra burst of flavor, add a pinch of paprika or a squeeze of fresh lemon juice over the top before baking. The garlic can be adjusted to taste—some people prefer a stronger garlic flavor, while others like it more subtle.

This dish is best served immediately, but leftovers can be stored in an airtight container in the fridge for up to 2 days. To reheat, place the fish in a baking dish, cover with foil, and bake at 275°F until warmed through. You can also freeze the cooked fish for up to 3 months—just thaw overnight in the fridge before reheating.

Step-by-Step Instructions for Baked Bluefish Mayonnaise

Follow these precise steps to achieve perfectly moist and flaky bluefish every time.

Step 1: Prepare the Mayonnaise Mixture

In a medium bowl, combine the 1 cup Mayonnaise, 2 tbsp Lemon Juice, 2 cloves Garlic Cloves (minced), 1 tsp Dijon Mustard, and 0.25 tsp Paprika. Mix until smooth and well combined. The mixture should have a uniform consistency and a subtle sheen. This mayonnaise mixture is the key to keeping the bluefish moist during baking.

Taste and adjust the seasoning as needed. You can add more lemon juice if you prefer a tangier flavor or more paprika for a smokier taste. Set the mixture aside until ready to use.

Step 2: Season the Bluefish Fillets

Pat the 4 pieces Bluefish Fillets dry with paper towels to remove excess moisture. This helps the mayonnaise mixture adhere evenly to the fish. Season both sides of the fillets with 1 tsp Salt and 0.5 tsp Black Pepper. Make sure to season evenly to ensure consistent flavor throughout.

Place the seasoned fillets on a plate or tray, ready for the mayonnaise coating. The fish should look evenly coated with the seasoning.

Step 3: Coat with Mayonnaise Mixture and Bake

Preheat your oven to 400°F. Grease a baking dish with 2 tbsp Olive Oil to prevent sticking. Place the bluefish fillets in the prepared baking dish. Spread the prepared mayonnaise mixture evenly over the top of each fillet, making sure they are fully coated.

Bake in the preheated oven for 12-15 minutes or until the fish is cooked through and flakes easily with a fork. The mayonnaise on top should be golden brown and slightly bubbly. Check for doneness by inserting a fork into the thickest part of the fillet; it should flake apart easily.

Step 4: Garnish and Serve

Once baked, remove the bluefish from the oven and let it rest for a minute or two. Sprinkle 0.25 cup Fresh Parsley and 0.25 cup Fresh Dill over the top of the fillets for garnish. The fresh herbs add a burst of color and freshness to the dish.

Serve the baked bluefish hot with 4 slices Lemon Slices on the side. The lemon slices can be squeezed over the fish for an extra burst of citrus flavor. Enjoy your perfectly cooked, moist, and flaky bluefish.

Troubleshooting Great baked bluefish mayonnaise

Common Baking Issues

One of the most common problems with baked bluefish is overcooking, which results in dry, tough fish. To avoid this, I always check the fish at the minimum recommended time (12 minutes) and then every minute after that until it flakes easily. Using a meat thermometer can help – the internal temperature should reach 145°F for food safety.

Mayonnaise Mixture Problems

If your mayonnaise mixture isn’t adhering evenly to the fish, try patting the fillets dry with paper towels before applying the sauce. I also

Preventing Dry Edges

To keep the edges of your bluefish from drying out, make sure they’re not touching each other in the baking dish. I space mine about 1 inch apart to allow for even air circulation. If you’re cooking a larger quantity, consider using multiple baking dishes rather than overcrowding one. Brushing the edges with a little extra olive oil can also help keep them moist.

Fixing Underseasoned Fish

If you taste your bluefish and find it’s underseasoned, don’t worry – there’s an easy fix. I sprinkle a pinch of flaky sea salt and a grind of black pepper over the top just before serving. You can also add a squeeze of fresh lemon juice for brightness. For next time, consider seasoning the fish more heavily before adding the mayonnaise mixture.

Dealing with Strong Fish Flavor

Bluefish can sometimes have a strong flavor that not everyone enjoys. To mellow this out, I recommend soaking the fillets in milk or buttermilk for 30 minutes before baking. The acidity helps neutralize some of the stronger flavors. You can also try adding more lemon juice or a bit more garlic to the mayonnaise mixture to balance the flavor.

Reheating Leftovers

If you’re reheating leftover bluefish, the key is to do it gently to prevent drying out the fish. I place the leftovers in a baking dish, cover with foil, and reheat in a 275°F oven until warmed through. You can also add a splash of white wine or extra lemon juice to help keep the fish moist during reheating.
