Ingredients
- Alaskan halibut fillets: provide a mild sweet flavor and firm texture perfect for baking without falling apart
- Fresh asparagus: adds a spring brightness and nutritional boost look for stalks with tight closed tips
- Cherry tomatoes: burst during cooking creating a natural light sauce choose bright colored firm tomatoes
- Minced garlic cloves: infuse everything with savory depth fresh is significantly better than pre minced
- Extra virgin olive oil: adds richness and helps everything roast properly select a good quality bottle
- Fresh dill: brings a delicate herbal note that pairs perfectly with seafood always opt for fresh over dried
- Lemon juice: brightens all the flavors and helps tenderize the fish use freshly squeezed for best results
Step-by-Step Instructions
- Preparation:
- Preheat your oven to 400°F while patting the halibut fillets completely dry with paper towels. This crucial step ensures proper browning and prevents the fish from becoming soggy during baking. Check carefully for any pin bones by running your fingertip along the flesh.
- Assemble The Dish:
- Arrange the trimmed asparagus in a single layer across the bottom of your baking dish creating a natural rack for the fish. Place the halibut fillets on top then scatter halved cherry tomatoes around everything. This layering method allows flavors to mingle while ensuring even cooking.
- Season Everything:
- Drizzle olive oil evenly across all ingredients making sure to coat the fish properly. Sprinkle minced garlic across everything ensuring some lands on each fillet. Season with salt and pepper applying slightly more to the fish than vegetables. Squeeze fresh lemon juice directly over the fillets then finish with a light dusting of chopped dill.
- Perfect Baking:
- Bake for exactly 15 minutes which gently cooks the fish while allowing vegetables to soften without becoming mushy. Switch to broil for the final 3 minutes which creates a beautiful light golden finish on the fish and slight char on vegetable edges.

Halibut has been my secret weapon for introducing reluctant seafood eaters to fish. Its mild flavor and meaty texture wins over even the most dedicated chicken lovers in my family. My nephew who claims to hate all seafood devoured two helpings at our last family dinner.
Perfect Pairings
This versatile halibut works beautifully with various side dishes. For a light summer meal serve alongside a crisp green salad dressed with lemon vinaigrette. During colder months pair with wild rice pilaf or roasted baby potatoes to create a more substantial dinner. The natural flavors complement almost any starchy side without overwhelming it.
Selecting Quality Halibut
The key to exceptional halibut is starting with the freshest fish possible. Look for fillets with translucent flesh that appears moist but not wet or slimy. The surface should spring back when gently pressed rather than leaving an indentation. Fresh halibut should smell clean and oceanic never fishy or ammonia like. If possible ask your fishmonger when the fish arrived and choose pieces with the skin on which helps protect the delicate flesh during cooking.
Troubleshooting Common Issues
If your halibut turns out dry you likely overcooked it. This delicate fish requires vigilant timing as it continues cooking briefly after removal from heat. For larger fillets consider using an instant read thermometer aiming for 130°F at the thickest part. Should your vegetables finish before the fish roast them for 10 minutes before adding the halibut. Conversely if vegetables remain too firm while the fish is done simply remove the cooked fish set it aside covered with foil and continue roasting the vegetables until tender.
Common Queries
- → How do I know when halibut is done?

- → What sides pair well with baked halibut?
Rice, couscous, or potatoes complement the flavors nicely. Light salads or roasted vegetables are also great choices.
- → Can I use a different fish instead of halibut?
Yes, mild white fish like cod or haddock work well in place of halibut, adjusting the cooking time as needed for thickness.
