    Quickly sauteed in butter and finished with lemon juice, this pan-fried rainbow trout is as easy as it's delicious.

    Ready in just 20 minutes, it's the perfect dish to make when you're not in the mood for an elaborate recipe.

    I cook fish and seafood recipes several times a week, including baked salmon, shrimp scampi, and grilled halibut. This rainbow trout recipe is one of my favorites.

    Rainbow trout is a delicious fish - a delicate version of salmon. The simple flavors of browned butter and lemon complement it well, and the quick preparation time is a bonus.

    Ingredients

    The ingredients needed to make pan-fried rainbow trout.

    You'll only need a few simple ingredients to make this recipe. The exact measurements are listed in the recipe card below. Here's an overview of what you'll need:

    • Rainbow trout: I buy frozen fillets at Trader Joe's. I defrost them overnight in the fridge, then rinse and pat dry.
    • To season: Kosher salt, black pepper, and garlic powder.
    • Fat for frying: I use a combination of butter and ghee. The addition of ghee helps prevent the butter from burning.
    • Lemon juice: I recommend using freshly squeezed lemon juice in this recipe.
    • Minced parsley: Mostly used for garnish, but it also adds a layer of flavor.

    Variations

    This is a simple recipe, and that's a big part of its appeal. So, I don't usually make too many changes. But if you'd like, adding more spices is an excellent way to change things up. When sprinkling the fish with garlic powder, I sometimes add a pinch of paprika and dried thyme.

    Another variation is to cook the fish in two tablespoons of olive oil instead of the butter/ghee combination. I tried it and liked it, but I prefer butter. It turns into browned butter and is delicious.

    Rainbow Trout Instructions

    Here's an overview of the steps for making this recipe. The detailed instructions are listed in the recipe card below.

    Pat the fish fillets dry with paper towels, then season them with salt and pepper on both sides.

    Heat the ghee and butter in a large nonstick skillet over medium-high heat. When the butter starts foaming, add the fish, skin side down.

    Cook the fish until the skin is browned, for about 3 minutes. Sprinkle the tops with garlic powder.

    Carefully flip the trout fillets, lower the heat to medium, and continue cooking until they're cooked through. This should take 2-3 more minutes.

    Add the lemon juice to the skillet and remove it from the heat. Transfer the fish fillets to plates, drizzle them with the pan juices, sprinkle with parsley, and serve.

    Expert Tips

    1. To help the skin brown, gently press on the fillets with a spatula to ensure the skin has full contact with the pan.
    2. The addition of ghee helps prevent the butter from burning. It will still brown, and you'll get delicious brown butter. But if the pan doesn't get overheated, it shouldn't burn.
    3. I add the garlic powder midway through cooking to ensure it doesn't burn.

    Recipe FAQs

    What is rainbow trout?

    This freshwater fish belongs to the same family as the Pacific salmon. Its skin is dark, its flesh is pink, and it has a distinctive red line, as shown in the photo below. Its flavor is similar to salmon but milder and more delicate.

    Trout has a red line.

    Should I cook fish with the skin on?

    Yes. Rainbow trout fillets are typically sold with the skin on, and that's good because the skin is fatty and delicious!

    The skin also provides a protective layer between the fish and the hot pan, helping protect the flesh from drying out.

    Why do you start cooking fish skin-side down?

    Cooking fish skin-side down has two advantages. The first is that it helps crisp up the skin. Typically, you cook the fish longer on the first side, so you want that side to be the skin side.

    The second advantage is that when it's time to flip the fish, it's easier to slide a spatula under the fish's skin than under its flesh.

    Serving Suggestions

    When plating the trout, I like to place it on a bed of sauteed spinach or steamed spinach. I cook the spinach first, then keep it in a warm oven (170°F) and cook the fish.

    I also like to serve this fish with steamed broccoli, sugar snap peas, roasted cherry tomatoes, or sauteed broccolini.

    Storing Leftovers

    You can keep the leftovers in the fridge, in an airtight container, for 2-3 days. Reheat them in the microwave, covered, at 50% power. You can also freeze the leftovers for up to a month.

    Notes

    • The addition of ghee helps prevent the butter from burning. It will still brown, and you'll get delicious brown butter, but as long as the pan doesn't get overheated, it shouldn't burn. If the pan seems to be heating too much, lower the heat. 
    • I add the garlic powder midway through cooking to ensure it doesn't burn.
    • You can keep the leftovers in the fridge, in an airtight container, for 2-3 days. Reheat them in the microwave, covered, at 50% power. You can also freeze the leftovers for up to a month.
