- Mayonnaise: This creamy base keeps the fish moist and melds all the flavors together beautifully.
- Lemon juice: Adds brightness and a subtle tang that lifts the entire dish.
- Parmesan cheese: Freshly grated is best for a nutty, savory crust that gets beautifully golden in the oven.
- Green onions: A pop of color and a mild onion flavor that complements the richness of the sauce.

How to Make Heavenly Halibut
Step 1: Prep Your Oven and Baking Dish
Start by preheating your oven to 400°F. This temperature is key for achieving that signature golden, bubbly topping without overcooking the fish. Lightly grease a baking dish to ensure your Heavenly Halibut fillets release easily and don’t stick—plus, cleanup is a breeze!
Step 2: Arrange the Halibut Fillets
Place your halibut fillets in a single layer in the prepared baking dish. Make sure there’s a little space between them so the heat can circulate evenly, helping each piece cook perfectly and soak up all those delicious flavors.
Step 3: Mix the Heavenly Topping
In a small bowl, combine the mayonnaise, lemon juice, Parmesan cheese, chopped green onions, garlic powder, and a sprinkle of salt and pepper. Stir until everything is well blended. This luscious mixture is what gives Heavenly Halibut its creamy, tangy, and ultra-savory edge.
Step 4: Smother the Fish
Spoon the topping generously over each fillet, smoothing it out so every inch is covered. Don’t be shy—this is where all of that crave-worthy flavor comes from! The topping will melt and brown in the oven, forming a gorgeous, slightly crisp crust.
Step 5: Bake to Perfection
Slide the dish into your preheated oven and bake for 12–15 minutes. You’ll know it’s ready when the topping is golden and bubbling, and the halibut flakes easily with a fork. Be careful not to over-bake; you want the fish to stay juicy and tender.
Step 6: Garnish and Serve
Once your Heavenly Halibut emerges from the oven, sprinkle with fresh parsley and add a few lemon wedges for a burst of color and freshness. Serve immediately for maximum wow factor!
How to Serve Heavenly Halibut
Garnishes
A sprinkle of chopped fresh parsley and a few lemon wedges add a bright, zesty finish to your Heavenly Halibut. These simple garnishes make each plate look inviting and provide a fresh counterpoint to the rich, creamy topping.
Side Dishes
Heavenly Halibut pairs beautifully with fluffy rice, roasted vegetables, or a crisp green salad. The mild flavor of the fish and the creamy topping make it super versatile—try it alongside garlic mashed potatoes or a medley of steamed asparagus and carrots for a colorful, satisfying meal.
Creative Ways to Present
For an elegant dinner, serve each fillet atop a bed of herbed quinoa and scatter microgreens over the top. Or, make it family-style by arranging the fillets on a large platter with seasonal roasted vegetables and plenty of lemon wedges. Heavenly Halibut also makes a stunning open-faced sandwich layered on toasted sourdough with arugula and a drizzle of extra lemon juice.
Make Ahead and Storage
Storing Leftovers
If you’re lucky enough to have leftovers, store your Heavenly Halibut in an airtight container in the refrigerator for up to two days. The topping may soften a bit, but the flavors will still be absolutely delicious.
Freezing
While freshly baked is always best, you can freeze leftover Heavenly Halibut for up to a month. Place cooled portions in a freezer-safe container, separating layers with parchment paper. Thaw overnight in the refrigerator before reheating for best results.
Reheating
To reheat, place the fillets in a baking dish, cover loosely with foil, and warm in a 325°F oven until heated through (about 10–15 minutes). This helps restore the creamy texture and prevents the fish from drying out.
FAQs
Can I use a different type Main Course
Absolutely! Cod, haddock, or any other firm white fish work wonderfully in this recipe. Just be sure to adjust the cooking time slightly if your fillets are thinner or thicker.
Is there a way to make this recipe lighter?
You can lighten up Heavenly Halibut by using reduced-fat mayonnaise or swapping in plain Greek yogurt for part of the mayo. The result is still creamy and flavorful, but with fewer calories and a bit more protein.
Can I make the topping in advance?
Yes, you can mix the mayonnaise, Parmesan, lemon juice, green onions, and seasonings up to a day ahead. Store it covered in the refrigerator, then spread over the fish just before baking for maximum convenience.
How do I know when the fish is done?
The best way to tell is to insert a fork into the thickest part of a fillet; if it flakes easily and is opaque throughout, your Heavenly Halibut is ready. The topping should also be golden and bubbling.
What wine pairs well with Heavenly Halibut?
A crisp, lemony Sauvignon Blanc or a lightly oaked Chardonnay are both excellent choices. Their acidity and freshness balance the rich, creamy topping beautifully.
