Roast Mixed Vegetables

Roast mixed vegetables in roasting tin.
Jump to Recipe

Up until about a year ago, we tended to only have roast mixed vegetables with a Sunday roast or at Christmas…don’t ask why…I can’t answer!! Then last April we picked up the food magazine from the local Co-op and there was a recipe for a spring potato salad…it’s delicious.   There are new potatoes, asparagus, and spring onions which are all cooked in the oven, and then sliced sugar snap peas and crumbled feta are added after, along with a yogurt dressing.   We have made it a few times, but it gave me the idea of roasting more than just the usual potatoes and root veg, which I’ve now cooked a few times since.   

This roast mixed vegetables recipe is a great side dish to have with fish, chicken, pork, meat….the choice is yours.   Try it with or without potatoes – sometimes it’s nice to have a baked potato, mash, or simply boiled potatoes!

So, let's get choosing the veg you fancy and get cooking!!

Tips

  • The selection of vegetables you want to roast is entirely up to you! Just bear in mind that some vegetables won’t need to be roasted for the full 35/40 minutes – potatoes are best to be parboiled (see tip below) and cooked for the full amount of time. Root vegetables and peppers also need the full cooking time.  
  • If including vegetables like broccoli, courgette, asparagus, green beans, spring onions or sugar snap peas, I'd suggest the following timings:
    • broccoli and courgette - 20 minutes
    • asparagus, green beans, spring onions, sugar snap peas - 15 minutes
  • Potatoes - I’d suggest that you parboil them first in boiling salted water for 3 to 8 minutes depending on the type of potatoes. For baby potatoes – slice in half lengthways and parboil in salted water for 3 minutes.   For potatoes like Maris Piper, Rooster, and King Edwards – peel (if you wish – I like to leave the skins on), cut into equal sized chunks, and parboil in salted water for 8 minutes.  Regardless of the type of potato, always drain and leave to dry in their own steam for a couple of minutes before adding to the roasting dish with the other vegetables you’ve chosen.
  • Herbs and Spices - try adding fresh herbs like rosemary, thyme or oregano, which roast beautifully and add flavour. You could also add a sprinkle of smoked paprika or cumin for a different taste profile.
  • Add Protein - you could add tofu, halloumi or chickpeas to the roasting tin for a more filling, protein-packed meal.
  • Leftovers - turn left over roast mixed vegetables into a delicious frittata or add them to a breakfast hash with eggs and sausage. You could also toss leftover veggies into a grain bowl or mix them into pasta with olive oil and grated parmesan for a quick lunch.
  • This roast mixed vegetables recipe is easily adapted if you're cooking for less or more people.

FREQUENTLY ASKED QUESTIONS

What vegetables roast the best?

Vegetables like carrots, courgette, peppers, sweet potatoes, broccoli, brussels sprouts, cauliflower, and butternut squash roast particularly well. Root vegetables like potatoes and carrots take longer, while softer vegetables like courgette and broccoli cook faster.

How can I make my roasted vegetables crispy?

To achieve crispy roasted vegetables, make sure to spread them out on the baking sheet in a single layer without overcrowding, roast at a high temperature (200C fan), and avoid adding too much oil. Turning the vegetables halfway through roasting can also help.

Can I roast frozen vegetables?

Yes - you can roast frozen vegetables. Be sure to toss them in oil and seasoning and spread them evenly on the baking sheet. They may take a little longer to cook and won’t be as crispy as fresh vegetables, but roasting is still a great way to cook them.

How long should I roast vegetables?

The cooking time depends on the type of vegetable. Root vegetables like potatoes and carrots typically take around 35 to 45 minutes, while softer vegetables like courgette, green beans, and asparagus will roast in about 15 to 20 minutes. Keep an eye on them and stir halfway through for even cooking.

How do I store leftover roasted vegetables?

Keep leftover roasted vegetables in an airtight container in the fridge for up to 3 days. You can reheat them in the oven at a low temperature (around 180C fan) or enjoy them cold in salads or grain bowls.

Can I season roasted vegetables with something other than oil?

Yes, you can roast vegetables with ghee, coconut oil, or even a light marinade using balsamic vinegar, lemon juice, or soy sauce for added flavour.

What can I serve with roasted vegetables?

Roasted vegetables are a versatile side dish that pairs well with roasted chicken, grilled fish, or pasta. They can also be served over grains like quinoa or rice for a vegetarian meal, or as a topping for pizza or salads.
