Roasted broccoli soup is full of deep garlicky roasted vegetable flavour and thickened up with white beans to keep it dairy-free and add some protein. Just 5 simple ingredients and under 40 minutes of cook time this vegan soup is perfect for any night of the week.

If you haven’t noticed already, roasting vegetables is a big thing in our household! We just love how roasting brings the flavour of the vegetable to another dimension, and if you don’t already roast your broccoli when making soup with it you are going to from now on.

How to Make Roasted Broccoli Soup
First, I chop the broccoli into bite-sized chunks. I also use the stem in this recipe. Did you know that broccoli stalks are edible? Simply cut off the bottom inch of the stalk, then trim off the tough exterior skin of the stalk with a vegetable peeler. This is a great way to reduce food waste. Chop the remaining interior of the stalk into bite-sized pieces.
Put all the broccoli pieces into a large bowl along with the diced onion, olive oil and crushed garlic. Season with salt and pepper and toss well to coat the vegetables.
Spread the vegetables out evenly across a large baking sheet. The pieces will roast better if they have space between them, and better roasting means better flavour!
Pop the tray in the oven for 20 mins.
When the vegetables have finished roasting, remove them from the oven and place them in a large pot on the stove. Add the vegetable stock and white beans, then bring the soup to a boil.
After the soup boils, reduce it to a simmer for 10 minutes then using an immersion blender blend the soup up in the pot until it reaches your desired consistency - I like my soup completely blended, James prefers his left a bit chunkier. If you don't have an immersion blender, you can blend the soup in your blender in two batches.
