Introduction
This Juicy Garlic Parmesan Baked Halibut offers a perfect combination of tender fish and a rich, savory topping. With roasted garlic and cheesy mayonnaise, it’s an easy yet impressive dish that will delight any seafood lover.

Ingredients
- 1/2 tbsp olive oil (for roasting garlic)
- 1 head garlic (for roasting)
- Kosher salt (to taste)
- 1 tbsp unsalted butter
- Freshly ground black pepper (to taste)
- 1 lb halibut fillets (about 1-inch thick)
- 1/2 cup mayonnaise
- 1/2 cup grated Parmesan cheese
- 6 roasted garlic cloves (mashed into a paste)
Instructions
- Step 1: Preheat your oven to 375˚F. Cut off the top of the garlic head and brush off some of the outer paper skin, keeping the cloves intact. Place the garlic on foil, drizzle with olive oil, wrap tightly and roast for 45 minutes until soft.
- Step 2: Increase oven temperature to 425˚F. Heat butter in an oven-proof pan over low heat. Season halibut fillets with salt and pepper. Add the fish to the melted butter and transfer the pan to the oven. Roast for about 10 minutes until cooked through and opaque.
- Step 3: While the fish cooks, blend the six roasted garlic cloves with mayonnaise and Parmesan cheese until smooth, creating a flavorful paste.
- Step 4: Remove the pan from the oven. Spread the garlic-Parmesan mixture generously over the halibut. Set the oven to high broil and return the pan for about 4 minutes, until the topping is golden brown.
- Step 5: Carefully take the pan out. Let the fish rest for a minute then serve immediately, enjoying the rich roasted and cheesy flavors.
Tips & Variations
- Use Kerrygold unsalted butter for a richer flavor, or substitute with any quality unsalted butter.
- Try adding a squeeze of fresh lemon juice before serving to brighten the dish.
- If you don’t have a broiler, finish the fish under a hot grill for similar browning.
- Roast extra garlic to use as a spread on bread or to enrich other recipes.
Storage
Store leftover halibut in an airtight container in the refrigerator for up to 2 days. Reheat gently in a low oven or microwave, but avoid overcooking to keep the fish tender. It’s best enjoyed fresh.

FAQs
Can I use other types of fish for this recipe?
Yes, firm white fish like cod, haddock, or sea bass can be used as substitutes. Adjust cooking times accordingly based on thickness.
Is it necessary to roast the garlic beforehand?
Roasting garlic softens its flavor and adds sweetness, improving the topping’s taste. While you could use raw garlic, the flavor will be much stronger and less mellow.

Ingredients
For the Roasted Garlic:
- 1/2 tbsp olive oil
- 1 head garlic
For the Halibut:
- Kosher salt, to taste
- 1 tbsp unsalted butter (preferably Kerrygold)
- Freshly ground black pepper, to taste
- 1 lb halibut fillets (about 1-inch thick)
For the Garlic Parmesan Topping:
- 1/2 cup mayonnaise (Hellmann’s recommended)
- 1/2 cup grated parmesan cheese
- 6 roasted garlic cloves (mashed into a paste)
Instructions
- Roast the Garlic: Preheat the oven to 375˚F. Cut off the top of the garlic head and brush away some of the outer skin, keeping the cloves intact. Place it on foil, drizzle with olive oil, then wrap tightly. Roast for 45 minutes until soft and caramelized, which brings out mellow, sweet garlic flavor.
- Prepare and Cook the Halibut: Increase the oven temperature to 425˚F. In an oven-proof pan, melt butter over low heat. Season halibut fillets on both sides with kosher salt and freshly ground black pepper. Add the fish to the pan and transfer to the oven. Roast for about 10 minutes, until the fish is opaque and just cooked through.
- Make the Garlic-Parmesan Topping: While the fish cooks, blend the six roasted garlic cloves with mayonnaise and grated parmesan cheese until smooth and creamy, creating a rich, flavorful topping.
- Broil the Halibut with Topping: Remove the pan from the oven once the fish is done roasting. Spread the garlic-parmesan mixture generously over the top of each fillet. Set the oven to high broil and return the pan to the oven for about 4 minutes, until the topping is golden brown and lightly crisp.
- Serve the Halibut: Carefully remove the pan from the oven and let the fish rest for one minute. Serve immediately to enjoy the aromatic roasted garlic and cheesy flavors alongside your favorite side dishes.
Notes
- Roasting a whole head of garlic allows you to use leftover roasted cloves in other recipes or as a savory spread.
- Use an oven-proof pan or skillet to easily transfer from stovetop to oven.
- Adjust the broiling time based on your oven’s intensity to avoid burning the topping.
- For even more flavor, consider adding a squeeze of fresh lemon juice just before serving.
