Roasted Vegetable Soup

Heyyy 🙂

How are you all? Happy I guess, it’s Friday woohoo!

This week I’ve been cooking for one, ughh I hate eating alone it’s one thing that should always be enjoyed with your nearest and dearest. So since Nathan is still working away I’ve been making meals that I can easily store any leftovers afterwards. This Roasted Vegetable Soup is perfect for that because it can be frozen in plastic containers and brought out on a rainy day when you need something warming and comforting.

Roasted Vegetable Soup

I absolutely adore roasted vegetables of any kind so I knew this soup would have beautiful flavours. I chose to use butternut squash (a favourite of mine), red pepper, eggplant/aubergine and of course garlic!

All the vegetables are roughly chopped then placed in a lined baking tray with some thyme leaves, seasoning and olive oil. I wrapped five garlic cloves in tin foil with a tiny drizzle of olive oil and roast it in the oven along side the veg until cooked through and delicious.

Meanwhile I sautéd one leek and red onion in a large pot until soft, added the roasted vegetables, garlic (removed from their skins) and water then let it simmer for 30 minutes.

The soup is then blitzed with a hand held blender until completely smooth and seasoned to taste with salt and pepper. When serving I top with grated pecorino cheese and extra pepper, the pecorino adds saltiness to the sweet vegetables and gives the soup such a wonderful flavour.

Like all soup this is perfect with big chunks of crusty bread for dunking, yum!

    In the ingredient list it doesn’t mention red onion but in the instructions it does. How much do you need? Thanks

      Oh so sorry Heather, I hadn’t noticed that mistake. You need 1 red onion for the recipe. I’ll amend it asap. Thank you.

    This looks so beautiful and warming. I’ve never added eggplant to a squash soup and now I’m wondering why not!

    This is such a great technique for soup, I make a completely different roasted veggie soup using beets, and the color is amazing ~ I love that you added butternut squash, it’s my fave <3
