This Lemon Garlic Butter Salmon is a weeknight lifesaver and a dinner-party showstopper all in one. Flaky, tender wild Alaskan salmon fillet gets a bright lemon-garlic butter glaze, a crunchy panko-Parmesan topping, and a side of crisp-tender roasted broccoli. The flavors are fresh and balanced—bright citrus, savory garlic, a touch of honey for sweetness, and a buttery finish—while the panko-parmesan crust adds irresistible texture. Whether you’re feeding a family or prepping a special meal, this recipe delivers comfort and elegance with minimal fuss.

Why this recipe works

Layered flavor: A quick pan sauce combines butter, garlic, lemon, honey, soy, and Dijon for sweet-savory brightness.
Texture contrast: The panko-Parmesan topping crisps up during baking while the salmon stays moist beneath.
Built-in veg: Roasting broccoli alongside the fish makes this a nearly complete meal with the same hands-on time.
Simple technique: Minimal steps, straightforward pantry ingredients, and a single baking sheet make cleanup easy.

Ingredients

1 wild Alaskan salmon fillet with or without skin (3-4 pounds)*
2 tablespoons unsalted butter
4-6 garlic cloves, minced
1/4 cup lemon juice
2 tablespoons honey
1 1/2 teaspoons reduced sodium soy sauce
1 1/2 teaspoons Dijon mustard
1 tablespoon chopped fresh parsley (or 1 teaspoon dried)
1 teaspoon salt
1 teaspoon onion powder
1/2 teaspoon dried dill
1/2 teaspoon paprika
1/4 teaspoon pepper
2/3 cup panko
2 tablespoons melted butter
1/2 cup freshly grated Parmesan
5 cups broccoli florets
2 1/2 tablespoons olive oil
1/4 teaspoon salt
1/8 teaspoon pepper

*Choose a single whole fillet 3–4 pounds; if your fishmonger cuts it into portions, keep the total weight in the same range. If the fillet has skin, you can cook it skin-on for easier handling—remove before serving if you prefer.

Equipment

Baking sheet or rimmed sheet pan

Step-by-step instructions

Follow these steps in order for the best Lemon Garlic Butter Salmon. The directions are rewritten for clarity, preserving the ingredient amounts and the original sequence.

Preheat the oven and prepare the pan: Preheat your oven to 400°F (205°C). Line a large rimmed baking sheet with parchment paper or foil for easier cleanup. Arrange the salmon fillet in the center of the prepared sheet, skin-side down if it has skin.
Make the lemon-garlic butter sauce: In a small saucepan or skillet over medium-low heat, melt 2 tablespoons unsalted butter. Add 4–6 minced garlic cloves and cook for 30–60 seconds, stirring, until fragrant but not browned. Remove from heat and stir in 1/4 cup lemon juice, 2 tablespoons honey, 1 1/2 teaspoons reduced sodium soy sauce, and 1 1/2 teaspoons Dijon mustard. Whisk until the mixture is smooth and combined.
Season the salmon: In a small bowl, combine 1 tablespoon chopped fresh parsley (or 1 teaspoon dried), 1 teaspoon salt, 1 teaspoon onion powder, 1/2 teaspoon dried dill, 1/2 teaspoon paprika, and 1/4 teaspoon pepper. Sprinkle this seasoning evenly over the top of the salmon fillet.
Brush the sauce over the fish: Spoon or brush about half of the warm lemon-garlic butter sauce over the seasoned salmon, spreading it into an even layer. Reserve the remaining sauce for serving or to add more flavor after baking.
Prepare the panko-Parmesan topping: In a medium bowl, mix 2/3 cup panko, 2 tablespoons melted butter, and 1/2 cup freshly grated Parmesan until the panko is evenly moistened and resembles wet sand. Taste and adjust with a little extra salt if desired—but remember the salmon seasoning already contains salt.
Top the salmon: Gently press the panko-Parmesan mixture over the top of the sauced salmon, spreading it evenly into a compact layer. This will form the crisp topping when baked.
Toss and arrange the broccoli: In a separate mixing bowl, toss 5 cups broccoli florets with 2 1/2 tablespoons olive oil, 1/4 teaspoon salt, and 1/8 teaspoon pepper until the florets are evenly coated. Spread the broccoli in a single layer around the salmon on the same baking sheet, leaving a small space between the vegetable and the fish so heat circulates.
Bake everything together: Place the baking sheet in the preheated oven and bake at 400°F (205°C) for 12–18 minutes. Cooking time will vary with fillet thickness: a 3–4 pound fillet may need toward the longer end of the range. The topping should be golden and the salmon should reach an internal temperature of 125–135°F (52–57°C) for medium doneness; it will continue to cook slightly while resting.
Broil for extra color (optional): If the panko topping needs more color, switch the oven to broil on high for 1–2 minutes—watch closely to avoid burning. Remove when the topping is golden and crisp.
Rest and serve: Remove the baking sheet from the oven and let the salmon rest for 3–5 minutes. Spoon any remaining lemon-garlic butter sauce over the fish and sprinkle with the reserved chopped parsley if desired. Serve the Lemon Garlic Butter Salmon with the roasted broccoli on the side and enjoy.

Doneness guide and tips

Check the thickest part of the fillet with a thermometer; 125–135°F (52–57°C) yields moist, slightly translucent center. For well-done, cook to 140°F (60°C), but watch carefully to avoid dryness.
If your fillet is very thick, tent loosely with foil for the first part of baking to prevent the topping from overbrowning, then remove the foil for the last 5–8 minutes to crisp the panko.
Use freshly grated Parmesan rather than pregrated for the best melt and flavor.
If you prefer a smokier topping, swap 1/4 teaspoon of the paprika for smoked paprika.

Make-ahead and storage

Prep the lemon-garlic butter sauce and panko mixture up to a day ahead; store separately covered in the refrigerator.
Leftovers keep in the fridge for up to 2 days. Reheat gently in a 300°F (150°C) oven until warmed through to preserve moisture and crisp the topping again for a few minutes under the broiler if needed.

Serving suggestions

Serve over steamed rice, quinoa, or creamy mashed potatoes to soak up the lemon-garlic butter.
A simple green salad or lemon-herb couscous pairs nicely for a complete meal.
A wedge of lemon on the side gives an extra bright finish at the table.

Flavor variations

Swap honey for maple syrup if you prefer a less floral sweetness.
Add 1/2 teaspoon red pepper flakes to the lemon-garlic butter for a touch of heat.
Mix in 1–2 tablespoons finely chopped toasted almonds or walnuts into the panko for extra crunch and nuttiness.

Notes

All ingredient amounts above match the recipe and should be used as listed for consistent results.
If your fishmonger removes the skin, proceed the same way—the fillet will still take the sauce and crisp topping beautifully.
Be mindful of oven differences; check the salmon a few minutes before the minimum time if your oven runs hot.

This Lemon Garlic Butter Salmon balances bright citrus, gentle sweetness, and savory depth with a satisfying crust and roasted broccoli—an elegant but approachable dish you can rely on any night of the week. Enjoy!
