Weeknight Slow Baked Trout With Citrus

For as simple as this slow baked trout with lemon and oranges is to prep and cook, it packs a LOT of flavor. And because the trout cooks slowly at a low temperature, the result is tender, moist fish that flakes easily.

Why we love this steelhead trout recipe so much:

The juices from the thinly sliced lemon and blood orange absorb into the trout giving it a wonderful bright, citrus taste!
It’s healthy! This recipe is low calorie, gluten-free, and easily adaptable to be dairy-free (instead of butter, use olive oil!). Trout is low fat, making it one of the healthiest fish that is also widely available in grocery stores and markets.
The prep time is less than 10 minutes, guaranteed!

It just doesn’t get better than this! If you’re a fan of tender baked seafood, be sure to check out our tried and true slow baked salmon recipe, as well as this baked cod with panko — both are total crowd pleasers!

Ingredients For Citrus Baked Trout Recipe

Steelhead trout: Similar in both appearance and taste to salmon, but smaller, thinner, and generally with a lower fat content.
Kosher salt + black pepper: To season the trout!
Onion salt: our favorite brand is from Trader Joe’s, but any seasoned onion powder or salt is fine. If you use onion powder, increase the Kosher salt by ¼ teaspoon.
Unsalted butter: You can certainly drizzle with olive oil instead, but trout is much more lean than salmon, so we like to season with butter to add a little richness.
Fresh dill: steelhead trout and fresh dill are a match made in heaven! Other fresh herbs you can substitute with: parsley, thyme leaves, or thinly sliced chives
Fresh citrus: lemons + blood oranges, though any thinly sliced citrus would work, such as other varieties of oranges, limes, or grapefruit.

You’ll also need a rimmed baking sheet, parchment paper (or aluminum foil), and a microplane zester.

Note: if you’re not making an entire side of trout and have a smaller piece to work with, you can bake this entirely in a pan or small skillet.

How To Bake Steelhead Trout

Pro tip: pat all seafood dry with a paper towel before cooking. Removing excess water or moisture will help the trout (or any fish, really) better absorb the flavor of the seasonings.

Place trout on a parchment lined baking sheet, then season liberally with Kosher salt, black pepper, and onion salt (or garlic salt). Next, zest one lemon and one blood orange right over the fish. Sprinkle with fresh dill leaves.

Using a sharp knife, hinly slice each fruit into ¼” thick slices. Layer the fish with alternating lemon slices and blood orange slices, covering the entirety of the flesh of the fish.

Bake for 25-30 minutes in a preheated oven, or until the trout reaches an internal temperature of 125-130F. It should easily flake with a fork!

We recommend the Thermapen MK4 to check for doneness on all meats!

Steelhead Trout vs Salmon

While both Steelhead trout and salmon have bright, vibrant orange-pink colored flesh, trout tends to be thinner and smaller. Which means it also cooks more quickly. Trout is also leaner than salmon, which has a naturally high fat content (which totally makes it delicious, don’t get me wrong!).

In terms of flavor, they’re quite similar. The only distinguishable difference, in general, is that salmon has a fattier mouthfeel. You can easily substitute trout for salmon in just about any recipe (or vice versa), but remember that trout often takes less time to cook.

What’s the difference between Steelhead Trout and Rainbow Trout? This is fascinating, but all steelhead trout start out as Rainbow Trout. It is only when they migrate to an ocean from freshwater that they are categorized as Steelhead Trout. Crazy cool!

Can I Use Salmon Or Some Other Type Of Fish?

Yes! As mentioned above, salmon and trout (rainbow trout or steelhead) are pretty interchangeable within recipes. Salmon will generally take longer to cook, as it is often larger and thicker. The exception to this rule is wild Coho salmon, which is extremely similar to trout, so it tends to have a similar cook time.

And if you can’t get your hands on a full side of trout, use individual fish fillets — one per person, usually about 6 oz a piece.

What To Serve With Baked Trout Recipes

Salads always make a great side dish! Our go-to is this house salad, but a big tray of roasted broccoli or Sicilian cauliflower would be just perfect.

Alternatively, if you’re looking for something a bit heartier, we love to serve this baked trout recipe with Israeli Couscous Salad or Red Skin Mashed Potatoes.

Hurry and run to the store to grab the ingredients, because you do not want to sit on this one! It’s too delicious not to share!
