Lemon Garlic Butter Salmon
Bright, buttery, and impossibly simple, this Lemon Garlic Butter Salmon is the kind of weeknight dinner that feels special without demanding an hour in the kitchen. A whole 1 wild Alaskan salmon fillet (3–4 pounds) bakes under a glossy lemon-garlic butter, topped with a crisp Parmesan-panko crust and served alongside roasted broccoli. The flavors are balanced: tang from lemon, savory depth from soy and Dijon, a touch of honey for sweetness, and fresh parsley to finish. This is a crowd-pleasing sheet-pan meal that’s perfect for company or an easy, elegant family dinner.
Why this recipe works
This recipe leans on a few tricks that keep salmon juicy and flavorful. First, a lemon-garlic butter sauce made with a little soy and Dijon adds layers of savory and tangy notes that penetrate the fish as it bakes. Second, a panko-Parmesan topping gives a satisfying crunch without overwhelming the tender flesh. Finally, roasting broccoli right on the same pan keeps cleanup minimal and lets the broccoli pick up a hint of salmon richness. The result is a balanced plate that feels restaurant-worthy but is genuinely simple to pull together.

- Small saucepan or microwave-safe bowl
- Mixing bowl
- Spoon or brush for spreading sauce
- Instant-read thermometer (optional)
Prep and timing
Total time: about 35–45 minutes. Active time: 15–20 minutes. This timeline assumes the oven is preheated and you’re arranging ingredients while it warms.
Step-by-step instructions
Follow these clear, sequential steps to make the Lemon Garlic Butter Salmon. The directions follow the order of the ingredients and keep amounts unchanged so the dish turns out consistently well.
- Preheat the oven: Heat your oven to 400°F (200°C). Line a large rimmed baking sheet with parchment paper or foil for easier cleanup, leaving a bit of extra material around the edges to catch any juices.
- Arrange the salmon: Place the 1 wild Alaskan salmon fillet (3–4 pounds) skin-side down on the prepared baking sheet if it has skin. If the fillet is skinless, place the fleshy side up. Pat the top of the fillet dry with paper towels so the butter mixture adheres well.
- Make the lemon-garlic butter sauce: In a small saucepan over low heat, melt 2 tablespoons unsalted butter. Add 4–6 garlic cloves, minced, and cook gently for 30–60 seconds 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 well combined.
- Season the sauce: Add 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 to the butter mixture. Stir to combine so the seasonings distribute evenly through the sauce.
- Coat the salmon: Using a spoon or a brush, spread about two-thirds of the lemon-garlic butter mixture evenly over the top of the salmon fillet. Reserve the remaining sauce to spoon over the finished salmon or to add extra flavor halfway through baking if desired.
- Make the panko-Parmesan topping: In a mixing bowl, combine 2/3 cup panko, 2 tablespoons melted butter, and 1/2 cup freshly grated Parmesan. Stir until the panko is evenly moistened and the Parmesan is evenly distributed. The mixture should be slightly crumbly but hold together when pressed.
- Top the salmon: Sprinkle the panko-Parmesan mixture evenly over the butter-coated salmon fillet, pressing gently so it adheres to the surface. Make sure to cover the flesh in a uniform layer for even browning and crispness.
- Prepare the broccoli: In a separate bowl, toss 5 cups broccoli florets with 2 1/2 tablespoons olive oil, 1/4 teaspoon salt, and 1/8 teaspoon pepper. Spread the broccoli in a single layer on the same baking sheet around the salmon, leaving some space so steam can escape and the broccoli roasts rather than steams. If your baking sheet is crowded, you can use a second sheet or roast the broccoli on a separate pan.
- Bake: Place the sheet pan in the preheated oven and bake at 400°F (200°C) for 12–18 minutes, depending on the thickness of the fillet. Check the salmon after 12 minutes: the top should be golden and the fish should flake easily with a fork at its thickest part. If needed, bake a few minutes longer until the internal temperature reaches 125–130°F for medium-rare to medium doneness, or 140°F if you prefer a firmer texture. The broccoli should be tender with slight char at the edges.
- Finish and rest: If you reserved some lemon-garlic butter, drizzle it over the hot salmon when it comes out of the oven. Let the salmon rest for 3–5 minutes before slicing to allow juices to redistribute. This also helps the panko topping set so it doesn’t slide off when you serve.
- Serve: Slice the salmon into portions and plate alongside the roasted broccoli. Garnish with an extra sprinkle of chopped fresh parsley and an optional lemon wedge for squeezing over the fish. Serve immediately for the best texture and flavor.
Taste and texture notes
The finished Lemon Garlic Butter Salmon should have a glossy, slightly sticky glaze from the lemon-garlic butter. The panko-Parmesan crust creates a contrasting crisp top that pairs wonderfully with the tender, flaky flesh beneath. The reduced sodium soy sauce and Dijon mustard add umami and tang without overpowering the lemon and garlic. Roasted broccoli provides a bright, vegetal counterpoint and a pleasant textural contrast.
Make-ahead tips and variations
- Make the butter sauce ahead: You can mix the lemon-garlic butter sauce 1 day ahead and store it in the refrigerator. Rewarm gently before using so the butter liquefies for easy spreading.
- Prep the panko topping: Combine the panko, melted butter, and Parmesan up to a day ahead and refrigerate in an airtight container. Bring to room temperature before sprinkling on the fish.
- Smaller fillets: If you’re working with individual salmon portions rather than a whole 3–4 pound fillet, reduce the baking time to 8–14 minutes depending on thickness.
- Herb swaps: If you don’t have fresh parsley, the recipe allows for 1 teaspoon dried parsley instead. Fresh herbs finish the dish with a brighter note, but dried herbs will still give good flavor when included in the butter sauce.
- Grain-free topping: To make a gluten-free version, substitute gluten-free panko or crushed almond meal for the panko and proceed with the same amounts.
Serving suggestions
Serve the Lemon Garlic Butter Salmon with simple sides that soak up the buttery sauce: steamed rice, creamy mashed potatoes, or a lemony couscous. A crisp green salad with a vinaigrette cuts through the richness, and warm crusty bread is perfect for sopping up any remaining sauce on the plate.
Storage and reheating
Store cooled leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a 300°F oven for about 10 minutes to preserve moisture and prevent the topping from burning. Alternatively, reheat individual portions in a skillet over low heat with a splash of water and a lid to steam briefly, which helps keep the salmon from drying out. Note that the panko topping is crispiest when freshly baked; it will soften in storage but still taste delicious.

Lemon Garlic Butter Salmon
Ingredients
Equipment
Method
- Preheat the oven to 400°F (200°C). Line a jelly roll pan with aluminum foil leaving about 2 inches of overhang on the long sides, spray lightly with nonstick spray, and place the salmon in the center of the foil (skin side down if present); fold the foil sides up snugly around the salmon and push the wrapped salmon to one side of the pan.
- In a medium microwave-safe bowl, combine 2 tablespoons unsalted butter and the minced garlic; microwave just until the butter is melted. Whisk in the lemon juice, honey, soy sauce, Dijon, 1 tablespoon chopped parsley, 1 teaspoon salt, 1 teaspoon onion powder, 1/2 teaspoon dried dill, 1/2 teaspoon paprika, and 1/4 teaspoon pepper until smooth.
- Pour the lemon garlic butter sauce evenly over the salmon.
- In a small bowl, stir the panko with 2 tablespoons melted butter and the 1/2 cup freshly grated Parmesan until the butter is absorbed. Pat the mixture evenly over the top of the salmon.
- Toss the broccoli florets with 2½ tablespoons olive oil, 1/4 teaspoon salt, and 1/8 teaspoon pepper and spread them in a single layer in the open space on the pan next to the salmon.
- Bake uncovered at 400°F for 12–15 minutes, depending on salmon thickness, until the fish flakes easily with a fork and the broccoli is tender.
- For a golden panko topping, broil about 1 minute more watching closely until the panko is lightly browned.
- Garnish with additional chopped fresh parsley if desired and season with extra salt and pepper to taste.
Notes
- I purchase mine at Costco without skin for a reasonable price.
