Tasty Homemade Ketchup Recipe for the Barbecue

I love ketchup; it goes with pretty much anything! When it comes to the barbecue, ketchup is king too. Sure, you can have barbecue sauce but why not spice it up with ketchup instead? I'm not talking about the stuff you buy off the shelves, but one that you make yourself that adds a bit of a heavenly kick to your meat. It's great to use as a dipping sauce for meat and side dishes alike. Sausages and homemade chips with this homemade ketchup is a great combination! Take a look at the recipe for homemade ketchup below. The list of ingredients might seem long, but it's actually really simple to make.



  • 4 roughly chopped onions
  • 250g roughly chopped celery5 tablespoons of olive oil
  • 4 sliced garlic cloves
  • 1 teaspoon of ground coriander
  • 1 short cinnamon stick
  • 1 teaspoon of allspice
  • 1/2 teaspoon of ground black pepper
  • 2 teaspoon of celery salt
  • 2kg of roughly chopped ripe tomatoes
  • 3 tablespoon of tomato purée
  • 1/2 teaspoon of Tabasco sauce (or substitute with a fresh chilli to spice it up!)
  • 150ml of white wine vinegar
  • 100g of golden caster sugar
Homemade Ketchup


Firstly, you can even finely chop the onions and celery yourself or whack them into a food processor. After this, heat up the oil in a large saucepan and add the onions and celery into the mix, before covering up and leaving them to soften over a low heat for about 5 mins. After 5 mins, add the garlic and cook for another 5 mins, before adding the spices and cooking for a further 1 min.

Tip all the remaining ingredients into the pan and bring it to the boil. Simmer the mix uncovered for 1 hour, checking to see if the tomatoes have turned squashy and the liquid has reduced by a few inches.

Add the mix to the blender - or hand blender - and whizz it until smooth. Sieve the liquid into a bowl and allow it to thicken while it cools. If it seems too runny then put it back into the pan and cook it for a little longer, stirring often, until the liquid content is reduced.



If you put the ketchup into an airtight container you can keep it in the fridge for up to 3 months, or freeze it for even longer.

Use a Landmann barbecue for cooking your food. This combined with your newly created ketchup will be sublime.
