This roasted spring veg recipe is a simple yet elegant dish featuring tenderstem broccoli, asparagus, and radishes, all tossed in a zesty lemon mustard dressing.

Here in Shropshire, spring seems to be bringing with it more sunshine but not so much the warmer temperatures. And while the longer days are welcomed, the still chilly temperatures mean I’m sticking with hot meals. These roast spring veg combine my favourite seasonal veggies and are the perfect side dish for any protein.

So, whether you’re planning an Easter Sunday feast or just looking for a delicious seasonal side dish, this recipe is bursting with flavour and colour.

Best seasoning for roasted spring vegetables

The dressing is, I think, simple but effective. It adds flavour to the vegetables as they roast without overpowering them completely.

Lemon – both the grated zest and juice. Tip: grate the zest BEFORE you squeeze the juice. This sounds so basic but I’ve lost count of the amount of times I forget and end up trying to grate the zest from floppy squeezed lemon halves!

Mustard – I use wholegrain for pretty much any recipe that requires mustard. It has a very distinctive (and rather lovely) flavour without being too strong. If you prefer a richer mustard flavour try Dijon or English.

Garlic and onion granules – I’ve used granules as they give all the flavour of fresh but without the peeling/chopping faff. You also won’t get bits of burnt garlic on your veggies!

Dried rosemary – use fresh if you’d prefer. Swap it out for fresh or dried thyme, oregano or marjoram.

How to make this spring or Easter side dish

1. Mix together the dressing ingredients in a shallow bowl.

2. Next, toss the trimmed asparagus in the dressing until well coated then lay onto a large lined baking tray.

3. Repeat with the broccoli and the halved radishes.

4. Roast in a preheated oven for 30-35 minutes. You want the vegetables to be tender but still with a bit of bite.

5. While they’re roasting toast some pine nuts (if using) in a dry frying pan. I do this over a very high heat (for speed) but watch them like a hawk. Nobody needs to hear the shrill squeal of a smoke alarm! Toss the pan frequently. You can also toast them in the oven for a few minutes with the veggies – again keeping a very keen eye on them!

6. When the vegetables are roasted, transfer to a serving dish and then sprinkle over the pine nuts, sliced spring onions and the fresh herbs.

Whether you’re cooking for one or for a houseful I believe food doesn’t have to be complicated to be full of FLAVOUR and I want to show you how.  I’ve been a rigorous meal planner for over a decade whilst embracing seasonal ingredients (because that’s where the real flavour is!)

I’m also a dedicated dog mum to Nooch and Baxter and enjoy cooking them homemade treats (many of which are posted here) when I’m not screaming at the tennis or devouring fantasy fiction.
