Ingredients You’ll Need
For the salmon and veggies:
- 4 salmon fillets (about 6 oz each, skin-on or skinless)
- 1 lb (450 g) baby potatoes, halved
- 2 cups broccoli florets (fresh or frozen, but fresh is best for crispiness)
- 2 tablespoons olive oil
- 1 teaspoon salt (divided)
- 1/2 teaspoon freshly ground black pepper (divided)
- 1/2 teaspoon paprika (optional, for color and flavor)
- 1/4 teaspoon garlic powder
For the lemon butter sauce:
- 1/4 cup (60 g) unsalted butter
- 3 cloves garlic, minced
- Juice of 1 large lemon (about 2 tablespoons)
- Zest of 1 lemon
- 1 tablespoon fresh parsley, chopped
- Pinch of red pepper flakes (optional, for heat)
Step-by-Step Instructions
Step 1 – Preheat and Prepare
- Preheat your oven to 425°F (220°C). This high temperature helps create crispy potatoes and perfectly roasted broccoli while keeping the salmon moist.
- Line a large baking sheet with parchment paper or lightly grease it with olive oil for easier cleanup.
Step 2 – Roast the Potatoes First
- In a large mixing bowl, toss the halved baby potatoes with 1 tablespoon olive oil, 1/2 teaspoon salt, 1/4 teaspoon black pepper, and paprika (if using).
- Spread the potatoes evenly on the baking sheet, cut side down, for maximum crispiness.
- Roast for 15 minutes before adding the other ingredients.
Step 3 – Prepare the Lemon Butter Sauce
- While the potatoes roast, melt butter in a small saucepan over medium heat.
- Add the minced garlic and sauté for about 30 seconds until fragrant (be careful not to burn it).
- Stir in the lemon juice, lemon zest, parsley, and a pinch of red pepper flakes if you like a hint of spice.
- Remove from heat and set aside.
Step 4 – Add Broccoli and Salmon
- After the potatoes have roasted for 15 minutes, remove the baking sheet from the oven.
- Push the potatoes to one side and add the broccoli florets to another section of the pan. Drizzle them with the remaining 1 tablespoon olive oil, season with the remaining salt and pepper, and toss to coat.
- Place the salmon fillets in the remaining space on the baking sheet, skin-side down if applicable.
- Brush each salmon fillet generously with the lemon butter sauce, reserving a little for serving.
Step 5 – Roast to Perfection
- Return the baking sheet to the oven and roast everything together for 12–15 minutes, depending on the thickness of your salmon.
- Salmon is done when it flakes easily with a fork and reaches an internal temperature of 145°F (63°C).
- Broccoli should be slightly crisp on the edges, and potatoes should be golden brown.
Step 6 – Serve and Enjoy
- Transfer the roasted salmon, crispy potatoes, and broccoli to plates.
- Drizzle the remaining lemon butter sauce over the salmon for an extra burst of flavor.
- Garnish with fresh parsley and extra lemon slices for a beautiful presentation.
Tips for the Best Results
- Crispy Potatoes Hack: Make sure your potatoes are dry before roasting to get maximum crispiness.
- Fresh Lemon: Use fresh lemon juice, not bottled, for the best flavor.
- Customize the Veggies: Swap broccoli for asparagus, green beans, or zucchini if you prefer.
- Meal Prep Friendly: This recipe reheats well for lunch the next day—just store in an airtight container.
