Total Time
Prep: 15 minutes
Cook: 30 minutes
Total: 45 minutes
Servings: 4
Ingredients
For the salmon:
4 salmon fillets (5–6 oz each), skin-on or skinless
3 tbsp unsalted butter, melted
2 tbsp olive oil
3 garlic cloves, minced
Juice and zest of 1 lemon
1 tsp Dijon mustard (optional, for extra depth)
½ tsp dried oregano or thyme
Salt and black pepper, to taste
Lemon slices and chopped parsley, for garnish
For the vegetables:
1 lb (450g) baby potatoes, halved
2 cups broccoli florets
2 tbsp olive oil
Salt, pepper, and a pinch of paprika
Instructions
Preheat Oven
Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper or foil.
Prep the Potatoes
In a bowl, toss halved baby potatoes with olive oil, salt, pepper, and paprika. Spread them on the baking sheet and roast for 15 minutes.
Make the Lemon Butter Sauce
While the potatoes roast, mix melted butter, olive oil, garlic, lemon juice, lemon zest, Dijon mustard (if using), oregano, salt, and pepper in a small bowl.
Add Broccoli and Salmon
After the potatoes have roasted for 15 minutes, remove the tray. Add the broccoli to one side and toss with a little olive oil and salt.
Nestle the salmon fillets between the vegetables. Spoon the lemon butter mixture over the salmon and drizzle the rest over the broccoli.
Roast Everything Together
Return the baking sheet to the oven and roast for another 12–15 minutes, or until the salmon is cooked through (internal temp 125–130°F / 50–54°C) and the vegetables are tender and golden.
Finish and Serve
Garnish the salmon with lemon slices and chopped parsley. Serve everything directly from the tray or plate it for an elegant touch.
Tips
Use room temperature salmon: Take the salmon out of the fridge 15–20 minutes before baking for even cooking.
Don’t overbake: Salmon continues to cook slightly after removal—pull it out just as it reaches 125–130°F (50–54°C) for moist, flaky results.
Broccoli tip: Cut florets evenly and not too small, or they may burn before the salmon finishes.
Line your tray: Parchment or foil makes cleanup easy and prevents sticking.
Variations:
Swap vegetables: Try asparagus, zucchini, bell peppers, or green beans in place of broccoli.
Add spice: Sprinkle the salmon with red pepper flakes or a touch of harissa for heat.
Mediterranean twist: Add olives, cherry tomatoes, and crumbled feta before the final 5 minutes of roasting.
Make it dairy-free: Use olive oil or a plant-based butter alternative.
Q&A
Q: Can I use frozen salmon?
A: Yes, just be sure to fully thaw and pat it dry before cooking to avoid excess moisture and ensure proper roasting.
Q: Can I cook everything on one tray?
A: Definitely. That’s the beauty of this recipe! Just stagger the cooking times as written—potatoes first, then add broccoli and salmon.
Q: What if I don’t have Dijon mustard?
A: You can skip it, or substitute with a pinch of cumin or a little honey for a different flavor depth.
Q: Is this good for meal prep?
A: Yes! Store in airtight containers for up to 3 days. Reheat gently to avoid overcooking the salmon.
