Ingredients for baked fish with mayo

Four simple ingredients create a restaurant-worthy dish with crispy crust and creamy center perfection.

The fish makes or breaks this dish—cod or tilapia work best since they stay moist while developing that crispy crust. Look for fillets with even thickness (about 1-inch) at Whole Foods or your local fishmonger. If you can't find fresh, frozen works fine—just thaw overnight in the fridge. The mayo isn't just for flavor; it keeps the fish incredibly tender. Duke's or Hellmann's are my go-tos—they've got the right balance of richness without overpowering. For the breadcrumbs, panko is non-negotiable—it stays crispy where regular breadcrumbs get soggy.

No mayo? Greek yogurt mixed with a little olive oil works surprisingly well (just skip the lemon juice). Short on panko? Crushed cornflakes or matzo meal make decent substitutes, though the texture won't be quite the same. Fresh parsley flakes? Dried parsley at one-third the amount gets you close, but fresh is worth hunting down at the market. The lemon juice can be bottled, but freshly squeezed makes a world of difference—it brightens everything. For the garlic powder, toasted whole garlic cloves ground fresh adds depth, but pre-ground is fine if you're in a rush.

This dish reheats beautifully—just pop it in the oven at 400°F for 5-7 minutes until crispy again. Store leftovers in an airtight container for up to 3 days, but honestly, it's best eaten fresh. The breading gets soggy if you wait too long, so plan to eat within 2 days if you're not freezing. For freezing, wrap individual portions in foil and keep them for up to 1 month—just bake straight from frozen at 400°F for 15-18 minutes.

Step-by-step instructions for baked fish with mayo recipe

Here's how to create that perfect balance of crispy crust and creamy center every time.

Start by creating three separate bowls for your breading station. In the first bowl, whisk together the 0.5 cup mayonnaise and 2 tablespoons fresh lemon juice until completely smooth. This tangy mayo mixture will become the creamy center that keeps the fish moist while baking.

In the second bowl, combine the 0.5 cup all-purpose flour with 1 teaspoon salt, 0.5 teaspoon black pepper, 1 teaspoon garlic powder, and 1 teaspoon dried parsley flakes. Mix well to distribute the seasonings evenly. This seasoned flour will create a flavorful barrier between the fish and breadcrumbs, ensuring maximum flavor in every bite.

Finally, in the third bowl, place the 0.75 cup panko breadcrumbs. These light, airy breadcrumbs will create the crispy crust we're after. The reason we use panko instead of regular breadcrumbs is that its larger flakes create more surface area for browning and crisping.

Pat each of the 4 white fish fillets completely dry with paper towels. You want them as dry as possible for that perfect crispy crust. Starting with one fillet at a time, press it gently into the seasoned flour mixture, coating both sides completely. Shake off any excess flour.

Next, dip the floured fillet into the mayonnaise mixture, ensuring it's fully coated. You'll see the mayo cling to the fish, creating that creamy center we're aiming for. Finally, press the fillet into the panko breadcrumbs, coating both sides thoroughly. Place the breaded fillet on a plate and repeat with the remaining fish.

Here's a pro tip: Work quickly but carefully. The breading needs to adhere well, but pressing too hard can cause the delicate fish to tear. If any fillets lose their breading during the process, simply re-dip them in the mayo and breadcrumbs before baking.

Preheat your oven to 425°F. While it's heating, lightly grease a baking dish with 1 tablespoon olive oil. Arrange the breaded fish fillets in a single layer in the prepared dish, leaving about 1 inch of space between each fillet. This spacing allows for even browning and crisping on all sides.

Bake the fish for 12-15 minutes, or until the edges are golden brown and the internal temperature reaches 145°F. You'll know it's done when the crust is crispy and the fish flakes easily with a fork. The mayonnaise inside should be warm but not runny—this is what creates that perfect creamy center.

If you're worried about the fish drying out, don't be. The mayo mixture we used acts as a moisture barrier, keeping the fish juicy while the breadcrumbs create that satisfying crunch. The high oven temperature ensures the breading gets crispy without overcooking the fish underneath.

Remove the baked fish from the oven and let it rest for 2-3 minutes on a wire rack. This brief resting period allows the juices to redistribute, ensuring each bite is as moist as the first. The breading will stay crispy during this time, so don't skip this step.

Serve the fish immediately with the 4 lemon wedges on the side. The bright acidity of the lemon will cut through the richness of the mayonnaise and complement the crispy breading. For an extra touch, sprinkle with additional dried parsley flakes before serving.

This dish delivers on both promises: a perfectly crispy crust that shatters with each bite and a creamy, moist center that melts in your mouth. The combination of textures and flavors makes this baked fish recipe a standout that's sure to impress.

Dietary considerations for these flavors

Mayo-Free Options

If you're avoiding mayo due to dietary restrictions or simply prefer a lighter texture, swap it for ½ cup plain Greek yogurt mixed with 1 tablespoon olive oil and 1 teaspoon lemon juice.

This keeps the fish moist while reducing fat content. For a vegan option, use ¼ cup silken tofu blended with 1 tablespoon nutritional yeast—it mimics mayo’s creaminess surprisingly well. 🌱

Gluten-Free Adaptations

Replace the all-purpose flour with ½ cup gluten-free all-purpose flour blend (like Bob’s Red Mill 1:1) for dredging. For breadcrumbs, use certified gluten-free panko or crush gluten-free cornflakes into fine crumbs.

Double-check all seasoning blends for hidden gluten—some garlic powders or parsley flakes contain additives. The texture stays crispy with these swaps! ✨

Lower-Fat Versions

Lighten the dish by using ¼ cup low-fat mayo (like Hellmann’s Light) mixed with 1 tablespoon Greek yogurt to maintain creaminess. Reduce panko to ½ cup and add 1 tablespoon crushed almond flour for extra crunch without excess calories.

Roast the fish at 400°F instead of 425°F to prevent excessive oil absorption from the breading.

Allergen-Friendly Tips

For egg allergies, replace the egg wash with 2 tablespoons aquafaba (chickpea brine) or 1 tablespoon cornstarch mixed with 3 tablespoons water. If nut allergies are a concern, avoid almond flour substitutes—stick to gluten-free cornflakes or crushed potato chips (like Lay’s Classic) for breading.

Always check labels on mayo and seasonings for hidden allergens like soy or dairy.

Keto Considerations

This recipe is naturally keto-friendly as written, but make these tweaks: Use full-fat mayo (no substitutions) for healthy fats, and ensure your panko is 100% almond flour-based (like Julian Bakery). Skip the flour dredge entirely—just coat fish directly in mayo and panko.

Garnish with chopped fresh dill instead of parsley to keep carbs minimal. This version keeps net carbs under 3g per serving! 💪
