Crispy Baked Perch Ingredients
For the Fish
• Ocean Perch Fillets – A mildly sweet fish that delivers a flaky texture; skin on adds extra flavor.
• Salt and Pepper – Essential for seasoning; feel free to adjust these to suit your taste.
For the Coating
• Dijon Mustard – Adds a tangy flavor and moisture; you can use yellow mustard as a substitute.
• Mayonnaise – Contributes creaminess and helps retain moisture during baking.
• Panko Breadcrumbs – Creates that crave-worthy crispy texture; regular breadcrumbs can work if needed.
• Grated Parmesan – Offers a salty, nutty flavor; finely grated is best for sticking to the fish.
• Herbs de Provence – Infuses aromatic herbs for more depth; Italian seasoning is a fine alternative.
For Baking
• Olive Oil Spray – Ensures even browning and keeps the fish from sticking to the pan; a refillable sprayer is super handy.

Step‑by‑Step Instructions for Crispy Baked Perch
Step 1: Preheat and Prepare
Begin by preheating your oven to 400°F (200°C). While the oven warms up, line a baking sheet with parchment paper or lightly oil it with cooking spray to prevent sticking. This foundational step ensures that your crispy baked perch has a perfect base to cook on, which will help achieve that golden, crunchy crust.
Step 2: Mix the Coating
In a shallow dish, combine the panko breadcrumbs, finely grated Parmesan, and a sprinkle of herbs de Provence. This flavorful mixture will create that irresistible topping for your crispy baked perch. Give the ingredients a good stir with a fork until evenly combined, allowing the aromas to blend beautifully while you prepare the fish.
Step 3: Prepare the Sauce
In a separate bowl, stir together the Dijon mustard and mayonnaise until smooth. This zesty sauce not only adds flavor but also keeps the perch moist during baking. Make sure the mixture is well-blended, as it will be the adhesive that helps the crumb topping stick wonderfully to the fish fillets.
Step 4: Season the Fish
Take your ocean perch fillets and pat them dry with paper towels. This step is crucial as it helps the coating adhere better. Season both sides of the fillets with salt and pepper to taste. Then, spread a generous amount of the Dijon-mayo mixture on the top side of each fillet, creating a flavorful barrier.
Step 5: Coat the Fillets
Dunk each fillet, mayonnaise-side down, into the breadcrumb mixture. Gently press the fillet into the crumbs to ensure an even coating. This step creates the crispy exterior you’ll love in your baked perch. Once coated, place the fillet back on the baking sheet, ensuring the breadcrumb side is facing up for that perfect crunch.
Step 6: Olive Oil Spray
Lightly spray the tops of the coated perch fillets with olive oil, ensuring an even layer across the breadcrumbs. This added step helps achieve a beautifully crispy surface as it bakes. The oil enhances browning while keeping the fish moist, making your crispy baked perch both delightful and well-textured.
Step 7: Baking Time
Carefully place the baking sheet in the preheated oven and bake your crispy baked perch for approximately 5-6 minutes. Keep an eye on the fillets during this time, as you want them to become golden and crispy. After the initial baking, switch your oven to broil for an additional 2-3 minutes to achieve that irresistible crunch on top, making it beautifully golden.
Step 8: Serve with Love
Once the perch is perfectly baked, remove it from the oven and let it cool for a minute. Serve the crispy baked perch warm with a fresh squeeze of lemon juice over the top for an added zing. This quick and easy seafood dinner is best enjoyed right away when the crust is still delightfully crunchy!

Make Ahead Options
Preparing your Crispy Baked Perch ahead of time is a fantastic way to save precious minutes during busy weeknights! You can coat the perch fillets with the Dijon-mayo mixture and breadcrumb topping up to 24 hours in advance; simply cover them tightly with plastic wrap and refrigerate. This not only enhances the flavor as it marinated but also ensures the coating sticks beautifully during baking. When you’re ready to serve, all you need to do is bake the prepped fillets straight from the fridge, adjusting the cooking time slightly, if necessary, to ensure they achieve that delightful crunch. Enjoy the deliciousness, knowing that you’ve cut down on meal prep while keeping the dish just as irresistible!
Storage Tips for Crispy Baked Perch
Fridge: Store leftover crispy baked perch in an airtight container and refrigerate for up to 2 days to keep it fresh.
Freezer: If you want to keep it longer, freeze the cooked fillets wrapped tightly in plastic wrap and foil for up to 2 months.
Reheating: When ready to enjoy again, reheat in the oven at 350°F (175°C) for about 10-15 minutes to maintain the crispy texture.
Avoid Moisture: Always ensure the perch is completely cooled before storing to prevent condensation, which can make the coating soggy.

Crispy Baked Perch Recipe FAQs
What type of ocean perch should I buy?
When selecting ocean perch fillets, look for vibrant, translucent flesh with no dark spots or a strong fishy odor; fresh catches are the best option. Certified sustainable seafood is always a more eco-friendly choice too.
How should I store leftover crispy baked perch?
Leftover crispy baked perch should be stored in an airtight container in the refrigerator for up to 2 days. To reheat, preheat your oven to 350°F (175°C) and warm the fillets for about 10-15 minutes to ensure they stay crispy.
Can I freeze crispy baked perch?
Absolutely! To freeze, allow the cooked perch to cool completely, then wrap each fillet tightly in plastic wrap followed by aluminum foil to prevent freezer burn. You can store them in the freezer for up to 2 months. When you’re ready to eat, let them defrost in the refrigerator overnight before reheating.
What if my breadcrumb coating isn’t sticking?
No worries! If your breadcrumbs aren’t adhering well, try the following: ensure the perch is properly patted dry to remove moisture, which helps the coating stick better. Additionally, be generous with the Dijon-mayo mixture, as it acts like glue for the breadcrumbs. If you’re using regular breadcrumbs, adding a bit more oil or seasoning can enhance adhesion.
Is this recipe suitable for people with dietary restrictions?
While the crispy baked perch is a delicious seafood alternative, it’s crucial to note that it contains allergens such as fish and dairy (from the mayonnaise and Parmesan). If you’re serving someone with a soy or dairy allergy, consider substituting the mayonnaise with a vegan alternative and using a dairy-free cheese option. Always check that your chosen ingredients fit any dietary needs!
How should I adjust cooking time for larger fillets?
If you opt for larger ocean perch fillets, you will need to extend your cooking time. Instead of broiling for just 2-3 minutes, check for an internal temperature of 145°F (63°C) and adjust the initial baking time by an additional 2-3 minutes as needed. Always ensure that the fish flakes easily with a fork for the best texture.
