Instructions

Preheat the oven to 400°F. Use paper towels to pat dry the halibut.

In a large oven-safe skillet or baking dish, add the trimmed asparagus. Top with the halibut filets and cherry tomatoes.

Season everything with extra virgin olive oil, minced garlic, salt and pepper. Squeeze lemon juice on top and sprinkle the fish with fresh dill.

Bake for 15 minutes, then set the oven to broil and broil on high for 3 minutes.

Remove the pan from the oven and serve with rice or couscous. Enjoy!

Essential Tips

Pat fish dry

Before seasoning, use paper towels to thoroughly pat the halibut dry. This ensures a golden sear and prevents the fish from steaming in its own moisture during baking.

Trim asparagus evenly

Cut the asparagus spears to a uniform length so they cook evenly. If using thick stalks, lightly peel the bottom third to tenderize them before baking.

Don't skip the broil

The 3-minute broil at the end adds a delightful crispness to the top layer of vegetables and fish, enhancing the dish's visual appeal and texture.

Use room-temperature fish

If your halibut was refrigerated, let it sit at room temperature for 10-15 minutes before baking. This helps it cook more evenly and prevents the center from being cold.

Lemon zest for extra zing

Add the zest of half a lemon along with the juice for a deeper lemon flavor. Sprinkle it over the fish just before baking to brighten every bite.

Smart Swaps & Variations

Mediterranean twist Swap lemon and dill for 1/4 cup kalamata olives, 1 teaspoon capers, and 1 tablespoon fresh oregano. Add a pinch of red pepper flakes for heat.

Tropical salsa topping Top the baked halibut with 1/2 cup diced mango, red bell pepper, and cilantro mixed with lime juice before serving.

Creamy sauce finish After baking, drizzle 2 tablespoons of Greek yogurt mixed with a pinch of garlic powder and lemon zest over the halibut and vegetables.

Herb crust Press 2 tablespoons of panko breadcrumbs mixed with 1 tablespoon chopped parsley and 1 teaspoon lemon zest onto the halibut before baking for a crunchy top.

What to Serve With This

Steamed jasmine rice or Israeli couscous to soak up the lemony juices.
A crisp green salad with arugula, shaved fennel, and a tangy champagne vinaigrette.
Garlic mashed potatoes or roasted baby potatoes for a heartier meal.
A glass of Sauvignon Blanc or Pinot Grigio to complement the citrus and fish.

Storage & Reheating

Storage

Store leftovers in an airtight container in the refrigerator for up to 2 days. The halibut and vegetables will keep their texture best when kept separate from any rice or couscous.

Reheating

Reheat gently in a skillet over low heat with a splash of water or lemon juice to prevent drying. Alternatively, warm individual portions in the microwave for 30 seconds, then finish under the broiler for 1-2 minutes to restore texture.

Expert Chef Tips

For extra moisture, add 1/4 cup white wine or vegetable broth to the skillet before baking. Cover with foil for the first 10 minutes, then uncover to let the liquid reduce slightly.
Use a meat thermometer to check the halibut's doneness-it should reach 145°F in the thickest part. Overcooking is the biggest mistake with halibut, so pull it out as soon as it hits the target temp.
If your oven runs hot, reduce the broil time to 2 minutes to prevent the fish from drying out. Keep a close eye to avoid burning the dill and garlic.

Equipment You’ll Need

Oven-safe skillet or baking dish (10-12 inches)

Frequently Asked Questions

Can I substitute another fish for halibut?

Yes! Cod, sea bass, or mahi-mahi work well, but halibut's firm texture holds up best. Adjust cooking time to 12-14 minutes total, as thinner fillets cook faster. Avoid delicate fish like tilapia, as they may fall apart.

What if I don't have an oven-safe skillet?

Use a glass or ceramic baking dish, but line it with parchment paper to prevent sticking. Alternatively, bake in a muffin tin lined with foil for individual portions.

Can I make this ahead for meal prep?

Assemble the dish up to the baking step (step 3) and refrigerate for up to 4 hours. Add an extra 2-3 minutes to the baking time when cooking from chilled. Avoid broiling until ready to serve.

How do I know when the halibut is done?

Halibut is done when it reaches 145°F internally and flakes easily with a fork. It will continue cooking slightly as it rests, so remove it from the oven just before it hits the target temp.

Can I use frozen halibut?

Yes, but thaw it completely in the fridge overnight first. Pat it dry thoroughly before baking to ensure proper browning. Frozen halibut may take 2-3 extra minutes to cook through.

What's the best way to trim asparagus?

Hold a spear and bend it near the base-the natural break point will give you the tender part. For even cooking, trim all spears to the same length. Save the trimmings for soup stock.

Can I add other vegetables?

Absolutely! Try zucchini, bell peppers, or green beans. Cut them into even-sized pieces so they cook uniformly. Avoid adding vegetables that release a lot of water, like mushrooms, as they can make the dish soggy.

How can I make this dish lower in sodium?

Use low-sodium soy sauce or coconut aminos instead of salt, and reduce the added salt to 1/2 teaspoon. Taste before seasoning and adjust to your preference.
