Cod Fish Recipes Baked — crunchy, salty, and impossibly simple: welcome to the Quick & Delicious Mayonnaise Panko Crusted Baked Fish guide that turns ordinary fillets into a weeknight superstar.

Cod Fish Recipes Baked — quick intro

If you want a dinner that looks like you tried but didn’t spend hours, this mayo + panko baked fish is your ticket. The mayonnaise keeps the fillet tender and juicy; the panko gives that airy, extra-crispy top that makes you forget you didn’t deep-fry anything. Perfect for busy families, date nights, or anyone who loves Yummy Seafood without the fuss.

Why you’ll love this recipe

  • Super crispy without frying — panko creates a lighter crunch than regular breadcrumbs.
  • Moist, flaky fish every time — mayo locks in juices so the fish never dries out.
  • Minimal prep, big payoff — you’ll spend more time setting the table than laminating the recipe.
  • Customizable — swap herbs, cheeses, or spices and call it a new dish.
    In short: it’s one of those Fish Dinner Recipes that feels fancy but behaves like a weekday hero.

The story behind the dish

I first made this on a rainy Tuesday when my oven felt like the only warm hug I could offer my family. I slathered mayo on cod (yes, mayo!), sprinkled panko, baked for 18 minutes, and suddenly the whole house smelled like a coastal bistro. Guests asked for seconds; my ego swelled; the dish stuck around in rotation. That’s the power of Fish Dishes Recipes done right — simple technique, great texture, instant crowd-pleaser.

Ingredients breakdown — what each part does (short blurbs)

  • 4 boneless, skinless fish fillets (cod, haddock, tilapia): Mild-flavored, firm flesh that flakes well. Cod is classic.
  • ½ cup mayonnaise: The secret MVP — it browns and seals in moisture. Use full-fat for best results.
  • 1 tbsp Dijon mustard (optional): Adds a gentle tang and helps emulsify the topping.
  • 1 tsp garlic powder + 1 tsp onion powder: Savory backbone — no fresh garlic fuss.
  • 1 tsp lemon juice: Brightens and balances richness.
  • Salt & pepper: Simple seasoning rules.
  • 1 cup panko breadcrumbs: Airy crumbs that toast up golden and crunchy.
  • 2 tbsp grated Parmesan: Umami and salt in one.
  • 2 tbsp chopped fresh parsley: Freshness and color.
  • 1 tsp lemon zest: Aroma that says “this is seafood.”
  • 1 tbsp olive oil: Helps crisp the crumbs in the oven.

How to make it — step-by-step (short, punchy)

  1. Preheat the oven to 400°F (200°C). Line a baking sheet with parchment.
  2. Pat fillets dry. Dry fish = better crust adhesion. Always.
  3. Mix mayo topping. Stir mayo, Dijon (if using), garlic powder, onion powder, lemon juice, salt, and pepper in a small bowl. Spread a thin, even layer atop each fillet.
  4. Combine panko mix. Toss panko, Parmesan, parsley, lemon zest, and olive oil until crumbs are moistened.
  5. Press crumbs on. Firmly pat the panko mix on top of the mayo-coated fillets — you want good contact.
  6. Bake. Place on the sheet and bake 15–20 minutes, depending on thickness. Crust should be golden; fish should flake easily with a fork.
  7. Finish with lemon. Squeeze a wedge over each piece and serve.

Pro tips for perfect results (bolded key tips)

  • Pat the fish completely dry before you start — moisture is the enemy of crunch.
  • Spread the mayo thinly but uniformly; too much will slide off, too little won’t bind crumbs.
  • Press the panko firmly into the mayo so it sticks and forms a solid crust.
  • Bake on a hot sheet — preheating the baking sheet for 5 minutes gives immediate sizzle.
  • Check thick fillets with a thermometer: 135–140°F (57–60°C) is ideal for flaky, juicy fish.
  • Don’t overbake — as soon as the fish flakes, pull it out. It continues cooking a bit while resting.
  • Serve immediately for the crispiest experience; leftovers get softer.

Tips for swapping fish (and why cod is great)

  • Cod is mild, meaty, and flakes nicely — classic choice.
  • Haddock behaves similarly with a slightly sweeter taste.
  • Tilapia is budget-friendly and bakes evenly.
  • Salmon works too but needs less time and pairs better with different seasoning (think dill and lemon).
    For Cod Fish Recipes specifically, this method keeps the humble cod interesting and restaurant-worthy.

Flavor variations to try

  • Spicy mayo: Mix Sriracha into the mayo for heat. Great for a bold Fish Recipes Baked twist.
  • Herb crust: Swap parsley for dill and thyme for a fresher note.
  • Citrus-parmesan: Add extra lemon zest and use pecorino instead of Parmesan for a sharper bite.
  • Coconut panko: Mix shredded coconut with panko for a tropical crunch — great with mild white fish.
  • Cajun: Add Cajun seasoning to the panko for a smoky kick.

Best ways to serve (pairings that win)

  • Steamed veggies or a green salad — keep it light and balanced.
  • Rice or mashed potatoes — for a heartier plate that soaks up crumbs and lemon butter.
  • Tartar sauce, lemon aioli, or chimichurri — a dipping sauce elevates the dish.
  • Crisp white wine or a citrusy beer — seafood-friendly sips.
    Serving this alongside simple sides turns a humble sheet into a full Seafood Dish Recipes moment.

Make-ahead, freezing, and leftovers

  • Freezing raw, crumbed fillets: Assemble, freeze on a tray, then seal in a bag. Bake straight from frozen at 400°F for 25–30 minutes.
  • Leftovers keep in the fridge for up to 48 hours. Reheat in a 350°F oven to help revive the crust. Microwave will cook the fish but ruin the crisp.
  • Pro tip: If prepping for a weeknight, combine the panko mix and mayo mix ahead of time; on cook night, pat, press, bake.

Why this is a smart healthy option

  • Baking not frying saves oil and calories.
  • Panko gives crunch with less fat than deep-frying.
  • White fish like cod provides lean protein and essential nutrients.
    This is exactly the kind of Fish Recipes Healthy dinner that tastes indulgent but checks the nutrition boxes.

Frequently Asked Questions (quick answers)

Can I use frozen fish?

Yes — thaw completely and pat dry before breading. You can also bake from frozen, but add 8–10 minutes.

Is mayo necessary?

It’s the easiest binder and keeps fish moist. Greek yogurt works in a pinch (for a tangy, lighter finish).

Can I air-fry this?

Definitely. Air fry at 380°F for about 10–12 minutes, flipping halfway, until golden and flaky.

What else can I mix in the panko?

Crushed cornflakes, finely chopped nuts, or grated hard cheese — each adds textured interest.

How do I get extra-crispy panko?

Toast panko lightly in a skillet with oil before pressing onto the fillets.

Common mistakes and how to avoid them (short bullets)

  • Don’t skip drying the fish — it ruins crunch.
  • Don’t slap crumbs on loosely — they’ll fall off. Press them.
  • Don’t overbake — fish dries quickly. Start checking at 12 minutes for thin fillets.
  • Make sure the oven is hot — cold or low heat equals soggy crumbs.

Quick menu ideas (weeknight menus)

  • Light & speedy: Panko fish + lemony arugula salad + couscous.
  • Comfort night: Panko fish + garlic mashed potatoes + steamed green beans.
  • Entertaining: Panko fish bites served with three dipping sauces — lemon aioli, sweet chili, herb yogurt.

Final thoughts — make it yours

This recipe fits neatly into the lineup of Fish Dishes Recipes you’ll go back to again and again. It’s forgiving, fast, and flexible: perfect for cooks who want big texture with minimal drama. Whether you’re trying to sneak more seafood into weeknight life or you want a simple but impressive Baked Cod option for guests, the mayo-panko crust is a game-changer.

Now go rinse a fillet, pat it dry, and slap on some mayo — your oven will do the rest. FYI, your family will thank you. And IMO, nothing beats that first crispy bite.

Ingredients

Scale

Fish & coating base

  • 4 boneless, skinless fillets (cod, haddock, or tilapia work great)
  • ½ cup mayonnaise
  • 1 Tbsp Dijon mustard (optional — adds zip)
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1 tsp fresh lemon juice
  • Salt and black pepper, to taste

Crunchy topping

  • 1 cup panko breadcrumbs
  • 2 Tbsp grated Parmesan
  • 2 Tbsp chopped fresh parsley (optional)
  • 1 tsp lemon zest (optional, for brightness)
  • 1 Tbsp olive oil


Instructions

  1. Heat the oven. Preheat to 400°F (200°C). Line a sheet pan with parchment or lightly grease it.
  2. Dry the fillets. Pat fish completely dry with paper towels — this helps the coating cling.
  3. Make the mayo spread. In a small bowl whisk together the mayonnaise, Dijon (if using), garlic powder, onion powder, lemon juice, and a pinch of salt and pepper.
  4. Spread the base. Smear a thin, even layer of the mayo mixture over the top of each fillet.
  5. Mix the panko topping. In another bowl combine panko, Parmesan, parsley, lemon zest, and olive oil. Stir until the crumbs feel slightly moistened and hold together when pressed.
  6. Press on the crust. Firmly press the panko mixture onto the mayo-coated side of each fillet so it adheres and forms an even layer.
  7. Bake. Arrange the fillets on the prepared pan, panko-side up. Roast 15–20 minutes (depending on thickness) until the crust is golden and the fish flakes easily with a fork.
  8. Serve. Finish with additional parsley or lemon wedges if you like. Pair with steamed veg, rice, or a simple salad.

Notes

Why these ingredients matter

  • Mayonnaise keeps the fillets juicy and acts as glue for the crumbs.

  • Panko gives that light, airy crunch you want without weighing the fish down.

  • Lemon (juice + zest) lifts the flavors and cuts the mayo’s richness.

  • Garlic & onion powder add savory depth without fiddly prep.

  • Parmesan adds a salty, umami note that pairs beautifully with white fish.


Quick tips for success

  • Dry fish = crispy crust. Don’t skip patting the fillets dry.

  • Press the crumbs so they form a stable topping that won’t fall off.

  • Watch the oven — once the fish flakes, it’s done. Overbaking dries it out.

  • For extra crunch, briefly broil the top for 1–2 minutes at the end (keep an eye on it).


Variations & swaps

  • Use Greek yogurt instead of mayo for a tangier, lighter binder.

  • Toss some smoked paprika into the panko for a smoky edge.

  • Add crushed cornflakes or chopped nuts to the panko for a different crunch.

  • Try salmon or trout — adjust baking time so fattier fish stays moist.


Storing & reheating

 

  • Refrigerate leftovers in an airtight container for up to 48 hours.

  • Reheat on a baking sheet in a 350°F oven to help the crust stay crisp (microwaving will soften it).
