Some dinners look impressive enough to serve to guests.
Others are designed specifically for those nights when you’re tired, hungry, and would strongly prefer the oven to do most of the work.
Fortunately, this recipe manages to be both.
This Garlic Butter Salmon with Sweet Potato & Broccoli Tray Bake delivers flaky salmon, caramelised sweet potato, tender broccoli, and a rich garlic butter coating, all cooked together on a single tray. It’s packed with nutrients, loaded with flavour, and requires very little effort beyond some chopping and occasional oven-related supervision.
For solo eaters, salmon can sometimes feel intimidating or expensive. Many recipes are designed for families, leaving you wondering what to do with half a kilo of fish and enough leftovers to feed a small fishing village.
Not this one.
This recipe is perfectly portioned for one person and makes an ideal winter dinner, healthy lunch, or meal-prep option.
Best of all, there’s only one tray to wash afterwards.
And honestly, that’s worth celebrating.

Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to:
200°C fan-forced
Line a baking tray with baking paper.
Step 2: Prepare the Sweet Potato
Place the diced sweet potato onto the tray.
Drizzle with:
- olive oil
- salt
- black pepper
Toss well to coat.
Spread into a single layer.
Roast for:
20 minutes
Sweet potato takes longer than salmon, so giving it a head start is essential.
Step 3: Prepare the Garlic Butter
While the sweet potato roasts, combine in a small bowl:
- melted butter
- garlic
- lemon zest
- lemon juice
- black pepper
Mix well.
Set aside.
Try not to eat it with a spoon.
Step 4: Add the Salmon & Broccoli
Remove the tray from the oven.
Add:
- broccoli florets
- salmon fillet
Brush the garlic butter mixture generously over the salmon.
Return the tray to the oven.
Roast for:
12–15 minutes
Or until:
- the salmon flakes easily with a fork
- the broccoli is tender
- the sweet potato is caramelised and soft
The safe internal temperature for salmon is 63°C.
However, many people prefer salmon cooked slightly less for a softer texture.
Cook according to your preference and food-safety comfort level.
Step 5: Finish & Serve
Remove from the oven.
Squeeze fresh lemon over the salmon.
Sprinkle with parsley if using.
Serve immediately.
