For the Lemon Butter Sauce
- 2 tablespoons butter – Adds richness and depth
- 3 garlic cloves, minced – Creates a fragrant, savory base
- ½ cup chicken or vegetable broth – Adds flavor and helps deglaze the pan
- ½ cup heavy cream – Gives the sauce a smooth, creamy texture
- 2 tablespoons fresh lemon juice – Brightens and balances the sauce
- 1 teaspoon lemon zest – Adds intense citrus aroma
- 1 teaspoon Dijon mustard – Enhances the tangy, savory profile
- 2 tablespoons fresh parsley, chopped – For freshness and garnish
Tools and Equipment
- Baking sheet – Ideal for roasting potatoes and broccoli
- Large skillet (cast iron or stainless steel) – Ensures even heat for searing salmon
- Tongs – Helpful for flipping salmon without breaking it
- Sharp knife and cutting board – For efficient prep
- Zester or microplane – Makes lemon zesting quick and easy
Step-by-Step Instructions
1. Roast the Vegetables
Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper or lightly grease it.
In a large bowl, toss the halved baby potatoes with 2 tablespoons olive oil, salt, and black pepper. Spread them evenly on the baking sheet and roast for 15 minutes.
Remove the baking sheet from the oven, add the broccoli florets, drizzle with the remaining 1 tablespoon olive oil, and gently toss. Return to the oven and roast for another 15 minutes, until the vegetables are golden and crispy.
2. Sear the Salmon
While the vegetables roast, season the salmon fillets generously with salt and black pepper.
Heat 2 tablespoons butter in a large skillet over medium heat. Once melted and lightly bubbling, place the salmon fillets skin-side down. Sear for 3–4 minutes per side, until golden brown and cooked through. Remove from the skillet and set aside.
3. Make the Lemon Butter Sauce
Reduce the heat to medium and add the minced garlic to the same skillet. Sauté for 30 seconds to 1 minute, stirring constantly until fragrant.
Pour in the broth, scraping up any browned bits from the bottom of the pan. Stir in the heavy cream, lemon juice, lemon zest, and Dijon mustard. Let the sauce simmer for 3–4 minutes, until slightly thickened.
Finish by stirring in the chopped parsley.
4. Combine and Serve
Return the salmon fillets to the skillet and spoon the lemon butter sauce over them. Cook for 2 minutes, just to warm the salmon and allow the flavors to meld.
Serve the roasted potatoes and broccoli on a plate, top with a salmon fillet, and drizzle generously with the lemon butter sauce. Garnish with extra parsley if desired.
Tips for Perfect Results
- Use fresh salmon with firm flesh and bright color for best texture
- Cut potatoes evenly to ensure consistent roasting
