We need more traybakes in our life
I don’t know about you, but I LOVE a traybake. Minimal washing up but a whole load of flavour. Plus that smug sense of achievement when you pull one out of the oven. And this lemon salmon traybake? It’s fresh, vibrant, colourful and absolutely packed with omega-3 goodness. Basically, it’s the perfect midweek dinner for the fish lover in your life (or the fish convert who still needs a bit of lemony persuasion). Because we need to be eating more fish in my opinion.

Tell me more about this salmon traybake…
This dish is everything I want from a one-pan dish. We’re talking crispy-edged baby potatoes, sweet caramelised onions, softened garlic, colourful peppers and a hint of green from tenderstem broccoli. Then those juicy, flaky salmon fillets, topped with lemon slices that roast away to give you that fresh, zesty hit. To keep things interesting, I’ve gone in with thyme, oregano, and a dusting of semolina to help crisp up the spuds.
One pot cooking is one way to make life that little bit easier
The beauty of a traybake is that it looks after itself. You chuck everything in, drizzle with olive oil, season it like you mean it, and let the oven do most of the work. No standing over a hob, no faff with multiple pans, and no tears at the mountain of washing up afterwards. In fact, once you’ve got this in the oven, you’ve got a solid 30–40 minutes of “me time” to pour a glass of wine, scroll TikTok or pretend you’re finally getting round to folding the laundry.
Healthy comfort food (that’s not boring because nobody wants that)
The best part? This traybake is healthy without being boring. You’ve got your omega-3 from the salmon, vitamins from the broccoli and peppers, fibre from the spuds, and a hit of fresh lemon to tie it all together. Serve with a dollop of garlicky yoghurt or a spoonful of herby mayo on the side too.
One for the traybake lovers

So go on treat yourself and whoever you’re feeding. Less washing up, more eating. This lemon salmon traybake is basically a love letter to weeknight dinners.
