Ingredients You’ll Need
For the Main Dish:
- 4 salmon fillets (skinless or skin-on)
- 1 lb baby potatoes (halved)
- 2 cups broccoli florets
- 2 tablespoons olive oil
- 1 teaspoon garlic powder
- Salt and black pepper to taste
For the Lemon Butter Sauce:
- 4 tablespoons butter, melted
- 2 tablespoons lemon juice (freshly squeezed)
- 1 teaspoon lemon zest
- 2 cloves garlic, minced
- 1 teaspoon Dijon mustard (optional, for depth)
- 1 tablespoon chopped parsley or dill (for garnish)
Step-by-Step Instructions
Step 1: Preheat and Prepare
Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper or foil for easy cleanup.
Pat the salmon fillets dry with paper towels — this helps them sear beautifully in the oven.
Step 2: Roast the Potatoes
Place your halved baby potatoes on the baking sheet. Drizzle with 1 tablespoon olive oil, season with salt, pepper, and half of the garlic powder, and toss to coat evenly.
Spread them out in a single layer and roast for 20 minutes, or until they start to turn golden and slightly crisp on the edges.
Step 3: Add Broccoli and Salmon
After 20 minutes, remove the tray from the oven. Push the potatoes to one side and add the broccoli florets to another section.
Drizzle broccoli with the remaining 1 tablespoon olive oil, and sprinkle lightly with salt and pepper.
Now, place the salmon fillets in the remaining space on the tray, skin side down if using skin-on salmon.
Step 4: Make the Lemon Butter Sauce
In a small bowl, whisk together the melted butter, lemon juice, lemon zest, minced garlic, and Dijon mustard (if using).
Pour half of this sauce over the salmon and brush to coat.
Step 5: Roast Everything Together
Return the baking sheet to the oven and roast for another 12–15 minutes, or until:
- Salmon flakes easily with a fork
- Potatoes are crisp and tender
- Broccoli is slightly caramelized at the edges
Step 6: Add the Final Touch
Drizzle the remaining lemon butter sauce over everything once it’s out of the oven. Sprinkle with chopped parsley or dill for a bright, fresh finish.
Serve hot and enjoy.
Cooking Tips & Tricks
1. Don’t Overcook the Salmon
Salmon cooks quickly — about 12–15 minutes is usually perfect. If using thinner fillets, start checking around 10 minutes.
2. Use Even-Sized Pieces
Cut the potatoes into similar-sized chunks to ensure even roasting.
3. Customize Your Veggies
No broccoli? Try asparagus, green beans, or zucchini. They all roast beautifully alongside salmon.
4. Add a Kick
A sprinkle of chili flakes or paprika adds gentle heat and extra flavor depth.
5. Finish with Fresh Herbs
Fresh dill, thyme, or parsley brighten the dish and make it look gorgeous on the plate.
Serving Suggestions
Pair this Lemon Butter Salmon with Roasted Potatoes & Broccoli with:
- A crisp green salad or Caesar salad
- A slice of garlic bread or buttery dinner rolls
- A glass of chilled white wine or sparkling water with lemon
For a lighter meal, skip the potatoes and double the broccoli — the lemon-butter sauce will keep it satisfying.
How to Store & Reheat
- Refrigerate: Store leftovers in an airtight container for up to 3 days.
- Reheat: Warm in the oven at 350°F (175°C) for 8–10 minutes or gently microwave until hot.
- Freeze: You can freeze cooked salmon (without the veggies) for up to 1 month.
Variations to Try
1. Garlic Herb Salmon
Add fresh rosemary, thyme, or basil to the lemon-butter sauce for an aromatic twist.
2. Mediterranean Style
Add cherry tomatoes, olives, and red onion slices before baking. Sprinkle with feta before serving.
3. Spicy Honey Lemon
Mix a teaspoon of honey and a pinch of cayenne pepper into the butter sauce for sweet heat.
4. Foil Packet Version
Wrap each salmon fillet, a handful of potatoes, and some broccoli in foil with sauce. Bake for 20–25 minutes for easy cleanup and juicy results.
5. Air Fryer Version
Cook potatoes and broccoli first at 375°F for 10–12 minutes. Add salmon and cook everything together for another 10 minutes.
