Getting dinner on the table during busy weeknights can feel like a real puzzle, especially when you want something that’s both healthy and tastes great.

What Kind of Trout Should I Use?
Rainbow trout is the most common variety you’ll find at the grocery store, and it works perfectly for this recipe. You can opt for either farm-raised or wild-caught trout – farm-raised tends to be milder in flavor and more readily available, while wild-caught has a more distinctive taste. When shopping, look for fillets with firm, pinkish flesh and a fresh, clean smell (there shouldn’t be any strong fishy odor). If you can’t find rainbow trout, steelhead trout makes an excellent substitute since it’s actually part of the same family and has a similar taste and texture. Just make sure to check for pin bones before cooking, even if the fish is labeled as deboned, as these tiny bones can sometimes be missed during processing.
Options for Substitutions
This fish recipe is pretty adaptable and here’s what you can swap if needed:
- Trout: While trout has a nice mild flavor, you can use other similar fish like salmon, arctic char, or tilapia. Just keep in mind that cooking times might need to be adjusted – thicker fillets will need a few extra minutes.
- Butter: You can replace butter with olive oil or ghee. If using olive oil, use about 3 tablespoons instead of ¼ cup since it’s more liquid than butter.
- Fresh garlic: If you’re out of fresh garlic, use ½ teaspoon of garlic powder instead. In a pinch, you could also use 1 teaspoon of pre-minced garlic from a jar.
- Lemon juice: Fresh is best, but bottled lemon juice works too. You could also try lime juice for a different twist, or white wine vinegar mixed with a bit of water (use 1½ tablespoons vinegar plus ½ tablespoon water).
- Dill: Not a fan of dill? Try using fresh thyme, basil, or tarragon instead. Each will give the dish its own unique taste while still complementing the fish nicely.
- Red pepper flakes: Since these are optional anyway, you can leave them out or try a dash of cayenne pepper or a squirt of hot sauce if you still want some heat.
Watch Out for These Mistakes While Cooking
The biggest mistake when cooking trout is overcooking it, which can turn this delicate fish dry and tough – the flesh should be opaque and flake easily with a fork, typically taking only 8-10 minutes per inch of thickness.
Another common error is not patting the fish dry before cooking, as excess moisture prevents proper browning and can make the fish steam instead of developing a nice golden crust – take a minute to thoroughly dry the fillet with paper towels.
Temperature control is crucial: starting with too hot a pan can burn the garlic and butter, making them bitter, so keep the heat at medium and watch carefully as the butter melts and the garlic becomes fragrant.
For the best flavor, avoid the temptation to skip the resting time – letting the fish rest for 3-5 minutes after cooking allows the juices to redistribute throughout the fillet, ensuring every bite is moist and flavorful.
What to Serve With Trout?
This buttery, lemony trout pairs perfectly with simple side dishes that let the fish stay in the spotlight. A scoop of fluffy rice pilaf or roasted baby potatoes will soak up all that tasty garlic butter sauce. For vegetables, try some steamed asparagus or green beans – they’re light enough to complement the fish without overpowering it. If you want to keep things extra fresh and simple, a mixed green salad with a light vinaigrette works great too, especially in warmer months.
Storage Instructions
Keep Fresh: Got leftover trout? Place it in an airtight container and pop it in the fridge within 2 hours of cooking. It’ll stay good for up to 3 days. The garlic lemon butter sauce will actually help keep the fish moist while it’s stored!
Freeze: If you want to save your trout for later, let it cool completely, then wrap it tightly in plastic wrap or aluminum foil and place it in a freezer bag. It’ll keep well for up to 2 months in the freezer. Just remember that the texture might be slightly different when thawed.
Warm Up: To enjoy your leftover trout, gently warm it in the oven at 275°F for about 10-15 minutes, or until just heated through. Try not to overheat it, as fish can dry out quickly. You can also eat it cold in salads or sandwiches – it’s actually pretty tasty this way!

Ingredients
- 2 to 2.5 pounds trout fillet (skin optional, pin bones taken out)
- ¼ cup unsalted butter, melted
- 2 garlic cloves, finely chopped
- 2 tablespoons lemon juice
- ½ teaspoon dried dill (or 1 teaspoon chopped fresh dill)
- 1 teaspoon crushed red pepper flakes (optional)
- 1 teaspoon salt
- ¼ teaspoon black pepper
- Chopped fresh herbs for garnish (such as parsley)
Step 1: Prepare the Baking Sheet and Preheat the Oven
Begin by preheating the oven to 375°F (190°C).
Position a rack in the middle of the oven.
Line a baking sheet with a large piece of foil and lightly spray it with cooking spray to prevent sticking.
This will form the basis for your easy cleanup and cooking method for the trout.
Step 2: Make the Sauce
In a small bowl, whisk together your sauce ingredients: melted butter, garlic, lemon juice, dill, red chili flakes, salt, and pepper.
This flavorful mixture will enhance the taste of the trout and provide a delightful glaze while cooking.
Step 3: Prepare the Trout and Foil Packet
Place the side of trout on the prepared foil.
Spoon the sauce generously over the top of the fish, ensuring even coverage.
Fold the sides of the foil to cover and seal the foil packet, ensuring it is snug but not tightly pressed against the fish, allowing some space for steam to circulate.
Step 4: Bake the Trout
Transfer the foil packet to the oven and bake for 15-20 minutes.
The cooking time will vary depending on the thickness of the trout.
The fish should be cooked through and easily flaked with a fork at its thickest part.
Step 5: Broil for a Crispy Finish
Once baking is complete, carefully open the foil packet, keeping in mind the hot steam.
Place the trout under the broiler for a couple of minutes to lightly brown and crisp the top.
Monitor it closely to avoid over-browning.
Step 6: Rest and Serve
Allow the trout to rest briefly before slicing.
Serve with a garnish of chopped parsley and lemon slices for added freshness and presentation.
Enjoy your delicious, oven-baked trout with zesty sauce.
