Pin it I was running late on a Wednesday evening, staring at a fridge full of vegetables that needed using and salmon fillets I'd optimistically bought two days earlier. The idea of juggling multiple pans felt exhausting, so I grabbed the biggest tray I owned and decided everything was going in together. That improvisational dinner turned into one of my most-requested weeknight meals, proof that sometimes the best recipes are born from mild panic and a reluctant commitment to doing dishes.
The first time I made this for friends, I served it straight from the tray in the center of the table, still steaming and smelling like garlic and thyme. Someone said it felt like being at a cozy bistro, and I didn't have the heart to admit I'd been too lazy to plate it properly. Now I serve it that way on purpose, because there's something warm and unpretentious about everyone helping themselves from the same pan.
Ingredients
- Salmon fillets: I prefer skin-on because it crisps up nicely and helps the fish hold together, but skinless works just as well if that's what you have.
- Baby potatoes: Halving them ensures they cook through in the same time as the salmon, and their cut sides get golden and slightly crispy against the tray.
- Carrots: Slicing them into sticks instead of rounds gives you more caramelized edges, which means more flavor.
- Red bell pepper: Adds a pop of sweetness and color, and it softens beautifully without turning mushy.
- Red onion: Cut into wedges so they stay intact and develop a mild, jammy sweetness in the oven.
- Green beans: They stay bright and tender-crisp, adding a fresh contrast to the richer salmon.
- Olive oil: Coats the vegetables so they roast instead of steam, and helps the sauce cling to the salmon.
- Dijon mustard: The backbone of the sauce, providing sharpness and a slight heat that balances the honey perfectly.
- Honey: Just enough sweetness to glaze the salmon and temper the mustard without turning the dish into dessert.
- Wholegrain mustard: Optional, but the little seeds add texture and a rustic, homemade feel to the sauce.
- Lemon juice: Brightens everything and cuts through the richness of the fish.
- Garlic: Minced finely so it melts into the sauce and perfumes the entire tray as it bakes.
- Dried thyme: A quiet herbal note that makes the whole dish smell like you've been cooking all day.
Instructions
- Preheat and Prep:
- Set your oven to 200°C and line your largest baking tray with parchment paper. This step matters more than you think, trust me on the parchment.
- Toss the Vegetables:
- In a big bowl, tumble the potatoes, carrots, pepper, onion, and green beans with olive oil, salt, and pepper until everything glistens. Spread them out in a single layer so they roast instead of steam.
- Give Them a Head Start:
- Slide the tray into the oven for 10 minutes. This ensures the vegetables get tender at the same time the salmon finishes, no mushy fish or crunchy potatoes.
- Make the Sauce:
- While the vegetables roast, whisk together the mustards, honey, lemon juice, olive oil, garlic, thyme, salt, and pepper in a small bowl. Taste it, it should be tangy with a whisper of sweetness.
- Nestle the Salmon:
- Pull the tray out and tuck the salmon fillets right into the vegetables. Brush each piece generously with the sauce, saving a little for the end.
- Bake Until Perfect:
- Return the tray to the oven for 10 to 12 minutes, until the salmon flakes easily and the vegetables are fork-tender. The kitchen will smell incredible.
- Finish and Serve:
- Drizzle the remaining sauce over the salmon before bringing the whole tray to the table. Garnish with herbs if you're feeling fancy, or just dig in.
Pin it One autumn evening, I made this for my sister after a long week, and she sat at my kitchen counter with a glass of wine, watching me pull the tray from the oven. She said it was the kind of meal that made her feel cared for without any fuss, and I realized that's exactly what I love about it too. It's generous without trying too hard.
Choosing Your Salmon
I usually reach for center-cut fillets because they cook evenly, but if you end up with tail pieces, just fold the thin end under itself so it doesn't overcook. Fresh is wonderful, but honestly, properly thawed frozen salmon works beautifully here, and I've done it more times than I'd like to admit. Just pat it very dry before brushing on the sauce, or the glaze won't stick.
Vegetable Variations
I've swapped in zucchini, asparagus, and cherry tomatoes depending on the season, and they all work as long as you keep the sizes roughly similar so everything finishes at the same time. In summer, I skip the potatoes entirely and add more peppers and tomatoes for a lighter feel. The beauty of this recipe is that it bends to whatever your fridge is offering without complaint.
Serving and Pairing
This is wonderful on its own, but I sometimes serve it with a bowl of fluffy rice or torn crusty bread to soak up the sauce that pools at the bottom of the tray. A crisp Sauvignon Blanc is my go-to pairing, though sparkling water with lemon works just as well on a weeknight. Leftovers, if you're lucky enough to have any, are excellent cold the next day straight from the fridge.
- Add a sprinkle of smoked paprika or chili flakes to the vegetables before roasting for a gentle kick.
- Serve with lemon wedges on the side for anyone who wants an extra burst of brightness.
- If you're feeding a crowd, double the recipe and use two trays, rotating them halfway through for even cooking.

Salmon is done when it flakes easily with a fork and has a slightly opaque appearance in the center.
- → Is the honey mustard sauce adjustable for flavor?
Absolutely, you can add more honey for sweetness or extra mustard for tang depending on your taste.
