Instructions

1
Heat oven to 425 ℉ (218 ℃).
2
Peel and cut an onion into slices. Put some olive oil with onions in a baking dish.
3
Place fish on top of the onions. Squeeze half a lemon over fish. Season with salt, pepper, and any other dry ingredient you fancy.
4
Slice the rest of the lemons thinly. Place the thinly sliced lemons over the top of fish.
5
Bake for about 25 minutes or until the fish is cooked through (depends on the thickness and size of fish).
6
Roast some veggies in a second pan if you like- it’s about the same cooking time.
7
Mash 6 large cloves of garlic with some salt using a mortar and pestle. Alternatively, mince the garlic finely.
8
Add butter to the pan (roughly 4 tablespoons).
9
Add the mashed garlic to the butter and cook on medium-high until garlic starts to turn golden.
10
Squeeze the juice from 1 whole lime to the sauce. Stir, take off the heat.
11
Spoon the sauce over the steelhead trout once the fish is out of the oven.

Tips & Notes

Pro tips

Pat the trout fillet dry before baking to encourage even cooking and prevent steaming.
Slice onions uniformly so they caramelize at the same rate and create an even aromatic base.
Make the garlic butter sauce while the fish bakes to avoid cooling it; drizzle over the finished trout just before serving.
Watch the thickest part of the fillet—it should turn from translucent to opaque; overcooking dries the delicate meat quickly.

Substitutions

steelhead trout fillet → salmon or arctic char fillet (same cooking time; slightly richer flavor)
lemon → lime only (use 2 limes in place of lemon; shifts to a brighter, more tropical profile)
Italian herb seasoning → mixed fresh herbs like dill, tarragon, or thyme (use same amount; fresher taste)
butter → ghee (note: use same amount; adds nuttier flavor and handles high heat better)

Storage & make-ahead

Store leftovers in an airtight container in the refrigerator for up to 2 days. Reheat gently at 325°F, covered, for 8–10 minutes.

Common Questions

How do you know when baked steelhead trout is done?

The flesh should be opaque and flake easily with a fork when tested at the thickest part. Typically 12–15 minutes at 400°F for a 1½ lb fillet.

Can you substitute steelhead trout with another fish?

Yes. Salmon, arctic char, or sea bass work well and have similar cooking times and mild, buttery flesh.

Should you remove the skin from steelhead trout before baking?

No. Keep the skin on; it protects the flesh, adds flavor, and is edible and nutritious when cooked through.

Can this recipe be made ahead?

Assemble the dish up to 4 hours ahead, cover, and refrigerate. Add 2–3 minutes to bake time if cooking cold. Prepare the garlic butter sauce just before serving for best flavor.
