Preheat the oven to 180c. Peel the beetroots and chop into quarters, dice the onion and crush the garlic.
Place the beetroot cubes onto a lined baking tray and drizzle over ½ of the olive oil. Sprinkle over the salt and roast in the oven for 45 minutes, turning halfway. They should be soft once cooked.
Meanwhile place the remaining olive oil in a large pan on a medium heat along with the diced onion and crushed garlic. Sauté on a low heat for 10-12 minutes until the onion has softened.
Once the beetroot has cooked place into the blender along with the vegetable stock and cooked onion and garlic. Blend until smooth.
Place back into the pan and heat through on the hob for a few minutes.Garnish with fresh dill and sunflower seeds to serve, and serve alongside some toast should you wish.
