Ingredients You’ll Need
Let’s gather our ingredients—this is where simple pantry staples transform into something magical. The beauty of this recipe lies in the quality and treatment of a few key components. First, the halibut: look for firm, glossy fillets that are about 1-inch thick for even cooking.
If they’re very uneven, you can ask your fishmonger to trim them. For the crust, panko breadcrumbs are non-negotiable for maximum crispiness; their light, flaky texture browns beautifully. Parmesan cheese must be freshly grated from a block—trust me, the pre-shredded stuff won’t melt or brown correctly due to added starches.
The mayonnaise acts as our magic glue and adds richness; a good-quality, full-fat mayo works best. Finally, fresh garlic and parsley bring the necessary brightness and punch. If you have lemon pepper or a favorite dried herb blend, feel free to add a pinch to the breadcrumb mixture for a personal touch.

Kitchen Equipment Needed
You won’t need any specialty gear for this recipe. A standard rimmed baking sheet is essential—the rim prevents any juices from spilling in your oven. Lining it with parchment paper or a silicone baking mat guarantees an easy release and even simpler cleanup.
You’ll need a medium mixing bowl for the dry crust ingredients and a small bowl for the mayonnaise binder. A microplane or fine grater is the best tool for turning your parmesan block into the fluffy, fine grate needed for the crust. A pastry brush is helpful for spreading the mayo, but the back of a spoon works just as well.
Finally, have a digital meat thermometer handy for perfect doneness; it takes the guesswork out of cooking fish.
How to Make Garlic Parmesan Crusted Halibut Recipe
Step 1: Prep the Fish and Oven
Start by getting your oven nice and hot—425°F is the sweet spot for cooking the fish through while crisping the crust without burning the garlic. While it heats, take a few paper towels and firmly pat the halibut fillets dry on all sides. Believe me, this is the most overlooked but critical step for getting that crust to stick.
Any surface moisture will steam the fish and create a barrier. Place the dry fillets on your parchment-lined baking sheet. A quick drizzle of olive oil and lemon juice, followed by a generous seasoning of salt and pepper on both sides, creates your flavor foundation.
Step 2: Create the Flavorful Crust
Now for the star of the show: the crust. In your mixing bowl, combine the panko, freshly grated parmesan, minced garlic, chopped parsley, and a pinch of salt. Use a fork to mix it all together, breaking up any clumps of garlic.
You’ll immediately smell the incredible aroma. Tip from me: if you have time, toasting the panko in a dry skillet for 2-3 minutes until lightly golden before mixing adds an even deeper, nuttier flavor to the final dish.
Step 3: Apply the Flavor “Glue”
In a small bowl, stir together the mayonnaise and Dijon mustard. The mustard is optional but adds a wonderful depth that cuts through the richness. Using a spoon or brush, spread a thin, even layer of this mixture over the top of each seasoned halibut fillet.
You want to cover the surface completely, but you don’t need a thick layer. Think of this as the mortar that will hold your crispy brick wall of flavor securely in place.
Step 4: Apply and Secure the Crust
Here comes the satisfying part. Take handfuls of your panko-parmesan mixture and generously pile it onto the mayonnaise-coated top of each fillet. Gently but firmly press the crumbs down with your hands to form an even, cohesive layer that adheres.
Don’t be shy—pack it on! Once all fillets are coated, I like to give them a very light mist or drizzle of olive oil over the crust. This promotes all-over, even browning and helps the panko achieve that perfect golden color.
Step 5: Bake, Rest, and Serve
Carefully transfer the baking sheet to the hot oven. Bake for 13-16 minutes. The exact time will depend on the thickness of your fillets.
You’re looking for a deeply golden-brown crust and for the fish to be opaque and flake easily at its thickest part. A thermometer should read 145°F. Trust me, halibut can go from perfect to dry quickly, so start checking at 13 minutes.
Once out of the oven, let the fish rest on the pan for 2-3 minutes—this allows the juices to redistribute. Serve immediately with fresh lemon wedges for squeezing over the top. Step back and admire your beautiful, crispy creation.
- The Dry Fish Rule: I can’t stress this enough. Patting the halibut completely dry with paper towels is the single most important step for crust adhesion. Any moisture will create steam and cause the topping to slide right off.
- Grate Your Own Parmesan: Pre-shredded cheese contains cellulose to prevent clumping, which also prevents proper melting and browning. Taking 60 seconds to grate a block of Parmigiano-Reggiano or a good-quality parmesan makes a world of difference in flavor and texture.
- The Mayonnaise Advantage: Using mayo as the binder is a professional kitchen hack. Its emulsified fat content helps the crust brown beautifully, and its consistency ensures it sticks without making the fish soggy, unlike heavier options like butter or cream.
- Don’t Crowd the Pan: Ensure the fillets have at least an inch of space between them on the baking sheet. Crowding creates steam, which is the enemy of a crispy crust. If necessary, use two sheets.
- The Visual Doneness Test: The fish is done when it flakes easily with a fork at its thickest part and has turned from translucent to opaque. If you see white protein droplets (albumin) on the surface, it’s a sign you’ve slightly overcooked it—it will still taste great, but be mindful for next time.
Recipe Variations
- Lemon-Herb Crust: Add the zest of one lemon to the panko mixture along with 2 tablespoons of finely chopped fresh dill or chives for a brighter, more herbaceous profile.
- Spicy Cajun Style: Mix 1.5 teaspoons of Cajun or Creole seasoning into the panko mixture. Swap the parsley for sliced green onions and consider adding a dash of hot sauce to the mayonnaise binder.
- Nutty & Gluten-Free: Replace the panko with 3/4 cup of finely ground almonds or almond flour. The result is a richer, denser crust that’s perfect for a keto or gluten-free diet.
- Everything Bagel Crust: Stir 2 tablespoons of everything bagel seasoning into the panko mixture. The sesame seeds, garlic, and onion create a fantastic savory crunch.
- Sun-Dried Tomato & Basil: Finely chop 1/4 cup of oil-packed sun-dried tomatoes and 2 tablespoons of fresh basil. Mix them into the panko in place of the parsley for a Mediterranean twist.
What to Serve With This Recipe
This Garlic Parmesan Crusted Halibut is a versatile centerpiece. For a light, balanced meal, pair it with a simple arugula salad dressed with lemon vinaigrette or a quinoa pilaf with roasted vegetables. If you’re craving comfort food, garlic mashed potatoes or creamy polenta are ideal for soaking up any delicious juices.
In spring, roasted asparagus or sautéed green beans make perfect seasonal partners. For a more formal dinner party, start with a classic tomato bisque and end with a lemon sorbet. Beverage-wise, a crisp Sauvignon Blanc or Pinot Grigio complements the dish beautifully, while a sparkling water with lemon is a refreshing non-alcoholic option.
Storage & Make-Ahead Instructions
- Refrigeration: Store any leftovers in an airtight container in the refrigerator for up to 2 days. The crust will soften due to moisture from the fish, but the flavor will still be excellent.
- Reheating: To restore some crispiness, reheat in a 375°F oven or toaster oven on a baking sheet for 8-10 minutes. Avoid the microwave, as it will make the crust soggy.
- Freezing (Not Recommended for Best Quality): You can freeze the uncrusted, seasoned fish fillets for up to 1 month. Thaw in the refrigerator overnight before proceeding with the recipe. I do not recommend freezing after baking, as the texture of the fish and crust will suffer significantly.
- Make-Ahead Strategy: You can prepare the panko-parmesan crust mixture up to 2 days in advance and store it in an airtight container in the fridge. Pat the fish dry and store it separately on a plate covered with plastic wrap in the fridge. Assemble and bake just before serving for the best texture.
Frequently Asked Questions
Q: Can I use a different type of fish?
Absolutely. This method works wonderfully with other firm, mild white fish like cod, haddock, or sea bass. Adjust baking time slightly based on the thickness of the fillets.
Thinner fillets may cook in 10-12 minutes.
Q: My crust isn’t sticking. What went wrong?
The most likely culprit is moisture on the surface of the fish. Always pat it bone-dry. Secondly, ensure you’re using enough of the mayonnaise binder to create a complete, thin layer for the crumbs to adhere to.
Q: Can I make this recipe gluten-free?
Yes, easily. Substitute the panko breadcrumbs with an equal amount of gluten-free panko or finely ground gluten-free crackers. All other ingredients are naturally gluten-free, but always check labels on mayonnaise and mustard.
Q: How do I know when the halibut is perfectly cooked?
The best method is to use an instant-read thermometer. Insert it into the thickest part of the fillet; it should read 145°F. Visually, the fish will be opaque and flake apart easily with a fork.
Q: Can I cook this in an air fryer?
Yes, and it works beautifully for a super-crispy result. Cook at 400°F for 9-12 minutes, depending on thickness. You may need to cook in batches to avoid overcrowding.
No need to flip.
Q: Is there a substitute for mayonnaise?
You can use an equal amount of full-fat Greek yogurt or sour cream, but note the crust may not brown quite as deeply or evenly. Melted butter is another option, but it can make the crust a bit greasier.
Q: Why is my crust browning too quickly?
If the crust is getting too dark before the fish is cooked, your oven rack is likely too high, or your oven runs hot. Tent the baking sheet loosely with aluminum foil for the remaining cook time to prevent burning.

Garlic Parmesan Crusted Halibut
Equipment
- Rimmed baking sheet
- Parchment paper or silicone baking mat
- Medium and small mixing bowls
- Microplane or fine grater for parmesan
- Pastry brush or spoon
Ingredients
- 4 fillets halibut skinless, 6-7 ounces each, about 1-inch thick
- 2 tbsp olive oil plus extra for drizzling
- 1 tbsp fresh lemon juice plus extra wedges for serving
- 1 tsp kosher salt divided
- 1/2 tsp black pepper freshly ground
- 1 cup panko breadcrumbs Japanese-style
- 3/4 cup parmesan cheese finely grated (not shredded), plus extra for serving
- 4 cloves garlic minced
- 1/4 cup fresh parsley finely chopped
- 1/3 cup mayonnaise full-fat recommended for best browning
- 1 tsp Dijon mustard optional, for extra flavor depth
Instructions
- Preheat your oven to 425°F (220°C). Pat the halibut fillets completely dry with paper towels. This is crucial for the crust to adhere properly. Place the fillets on a parchment-lined baking sheet. Drizzle lightly with olive oil and the lemon juice, then season both sides evenly with 3/4 teaspoon of the kosher salt and all the black pepper.
- In a medium bowl, combine the panko breadcrumbs, grated parmesan, minced garlic, chopped parsley, and the remaining 1/4 teaspoon of salt. Use a fork to mix everything thoroughly, ensuring the garlic is evenly distributed. The panko will stay crispier than regular breadcrumbs, giving you that perfect texture.
- In a small bowl, stir together the mayonnaise and Dijon mustard (if using). Using a spoon or brush, spread a thin, even layer of this mixture over the top of each seasoned halibut fillet. This acts as the ‘glue’ for your crust and adds incredible richness.
- Generously press the panko-parmesan mixture onto the mayonnaise-coated top of each fillet, creating an even layer. Gently pat it down so it adheres. Drizzle or spray the tops very lightly with a bit more olive oil—this promotes even, golden browning.
- Bake in the preheated oven for 13-16 minutes. You’re looking for the crust to be deeply golden brown and the fish to be opaque and flake easily with a fork at its thickest part. Avoid overcooking. Let the fish rest on the pan for 2-3 minutes before serving with extra lemon wedges and a sprinkle of fresh parsley or parmesan.
