Recipe Name:  Roasted butternut squash and sage soup


Meal Type: Lunch, Starter
Prep Time: 30 Mins

Cook time: 2 Hours

Servings: Six Bowls

"Few things beat a steaming hot bowl of homemade soup on a cold day! This butternut squash soup is deliciously smooth and velvety in texture.Roasting the squash adds to the flavour and I’ve saved time by roasting the onions alongside. It is really worth making your own chicken stock – so easy in the Aga range cooker! See my recipe below for stock made overnight in the simmering oven -  and have a try next time you have roast chicken!" Antonia


  • 1 large butternut squash (approximately 850g prepared weight)
  • 2 medium onions
  • 2 cloves garlic
  • 2 tbsp. olive oil
  • 1 tbsp. finely chopped fresh sage
  • 1 litre chicken or vegetable stock (see below)
  • You May Need....


    1. Peel the squash and cut into chunky cubes, discarding the seeds. Cut the onions into wedges. Put the squash, onions and garlic cloves (unpeeled) into a large bowl and pour over the olive oil. Season with salt and pepper and mix thoroughly to ensure everything is well-coated in the oil.
    2. Tip onto a large baking tray and slide onto the second set of runners in the roasting oven.  Roast for 40 minutes. Five minutes before the end of the roasting time, sprinkle on the sage and return to the oven.
    3. Pour the stock into a large saucepan or casserole and bring to the boil on the boiling plate. Remove the garlic cloves from the baking tray and squeeze out the roasted garlic into the stock. Tip the roasted squash and onions into the stock and bring back to the boil.
    4. Blend the soup, using a stick blender until smooth. Season to taste.

    Antonia's tips: Why not serve the soup with some croutons, so simple to make in your aga range cooker? Coat cubes of stale bread in olive oil and spread out onto a baking tray or roasting tin. Place onto the floor of the roasting oven for approximately 5 minutes – turn every few minutes and keep a close eye to be sure they don’t burn! Crispy sage leaves also make an attractive and flavoursome topping. Brush the sage leaves with a little olive oil and place on the tray alongside the croutons until crisp - YUM! 

      Chicken stock

      "Making stock in your aga range cooker is so simple! You simply throw everything into a big pot, bring to the boil and then leave in the simmering oven overnight. The next morning you have a big pan of flavoursome stock to use in soups, sauces and risottos. I freeze this in small bags or pots, ready to use whenever I have need." Antonia

      Our friend Barbara and Blake & Bull community member gave us this tip too, freeze your bones until you are ready to use them!

      How to make chicken stock in the simmering oven overnight in an Aga range cooker

      Method - so easy!

      1. Roughly chop the vegetables (no need to peel – just a quick wash) and place into a large pan with the chicken carcass and other flavourings. Cover with water and bring to the boil on the boiling plate.
      2. Place a lid on the pan and transfer to the simmering oven overnight (or for a minimum of 6 hours). In the morning, remove from oven and skim off any scum that has risen to the surface. Strain the stock and use immediately or freeze for use at a later date.

      Antonia's tips:

      Use whatever vegetables you have to flavour the stock – the above is a guide only. Add herbs - lovage for example intensifies the celery flavour.
