Ingredients You’ll Need
Gathering the right ingredients is the first step to nailing the Garlic Parmesan Crusted Halibut Recipe. Each component is straightforward but plays an essential role — from bringing crunch and richness to a bright, tangy finish.
- Halibut fillets: Use fresh, firm fillets about 6 ounces each for perfect portioning and texture.
- Grated Parmesan cheese: Adds a nutty, salty flavor that crisps beautifully in the oven.
- Panko breadcrumbs: Provides light, airy crunch that makes the crust irresistible.
- Fresh parsley: Finely chopped for a pop of herbaceous green and fresh aroma.
- Minced garlic cloves: Infuses the crust with robust, savory notes.
- Salt and black pepper: Simple seasonings that bring out the fish’s natural flavors.
- Mayonnaise: Binds the crust while keeping the fish moist and luscious.
- Dijon mustard: Adds a gentle tang and depth to the mayo mixture.
- Lemon juice: Brightens the dish with a fresh citrus kick.
- Olive oil: Helps achieve a golden crust by enhancing browning in the oven.
- Lemon wedges: For serving, to add a splash of fresh acidity.
How to Make Garlic Parmesan Crusted Halibut Recipe
Step 1: Prep Your Oven and Baking Dish
Preheat your oven to 425°F (220°C) to ensure it’s hot enough to cook the fish quickly and develop that beautiful crust. Line a baking sheet with parchment paper or lightly grease a baking dish so your halibut won’t stick during baking.
Step 2: Mix the Crunchy Crust Ingredients
In a small bowl, combine the grated Parmesan, panko breadcrumbs, chopped parsley, minced garlic, salt, and black pepper. This mixture will create the flavorful, crispy top layer that defines the Garlic Parmesan Crusted Halibut Recipe.
Step 3: Prepare the Mayo Mixture
Whisk together the mayonnaise, Dijon mustard, and lemon juice in another bowl. This creamy blend not only adds moisture but also acts as glue for the Parmesan crust, helping it stick beautifully to the fish.
Step 4: Ready the Halibut Fillets
Pat your halibut fillets dry using paper towels — this step is crucial to crisping up the crust. Then arrange the fillets on your prepared baking sheet, giving each enough space to bake evenly.
Step 5: Assemble the Crust
Brush the top of each halibut fillet generously with the mayonnaise mixture, then press the Parmesan crust mixture firmly onto the mayo-coated surface. Finally, drizzle olive oil lightly over the top to help achieve that gorgeous golden-brown finish.
Step 6: Bake to Perfection
Bake in the preheated oven for 12 to 15 minutes, or until the fish flakes easily with a fork and the crust is crisp and golden. For an ultra-crispy finish, broil the halibut for an additional 1 to 2 minutes, keeping a close eye to prevent burning.

Side Dishes
This Garlic Parmesan Crusted Halibut Recipe pairs beautifully with roasted vegetables like asparagus or Brussels sprouts, or a simple green salad to keep the meal light yet satisfying. Creamy mashed potatoes or a quinoa salad also work wonderfully for a heartier option.

Make Ahead and Storage
Storing Leftovers
Place any leftover halibut in an airtight container and refrigerate within two hours of cooking. It’s best enjoyed within 2 days to keep the crust as crisp and the fish as fresh as possible.
Freezing
This dish freezes well if wrapped tightly in plastic wrap and then foil or stored in a freezer-safe container. Freeze for up to 1 month. To maintain crust texture, it’s recommended to reheat using an oven or air fryer rather than a microwave.
Reheating
To reheat, place the halibut on a baking sheet and warm it in a preheated 350°F (175°C) oven for 10 to 15 minutes or until heated through and crust is crispy again. Avoid microwaving to prevent sogginess.
FAQs
Can I use another type of fish for this recipe?
Absolutely! Cod, haddock, or even tilapia work wonderfully as substitutes for halibut when making the Garlic Parmesan Crusted Halibut Recipe. The method stays the same and the flavors are just as delightful.
Is this recipe gluten-free?
It can be easily gluten-free by swapping regular panko breadcrumbs for gluten-free panko. The rest of the ingredients are naturally gluten-free, making this dish suitable for those with gluten sensitivities.
Can I make the crumb mixture ahead of time?
Yes, you can prepare the Parmesan and breadcrumb mixture a day ahead and store it in an airtight container. Freshly minced garlic and parsley are best added just before assembly to keep their vibrant flavors.
How do I know when the halibut is done?
The fish is perfectly cooked when it flakes easily with a fork and reaches an internal temperature of 145°F (63°C). The crust should be golden and crunchy as a visual cue.
What if I don’t have mayonnaise or Dijon mustard?
You can substitute mayonnaise with Greek yogurt for a lighter option, and if you don’t have Dijon mustard, a bit of yellow mustard or even a pinch of mustard powder will still provide a similar tang.
