Slow cooker tomato sauce recipe….

This recipe for homemade tomato sauce is one of the most versatile things you can make because it can be used to make so many meals.  I make a huge batch in the slow cooker and freeze it in smaller portions so I just need to re-heat it as and when I need it.

I use it for the sauce for tuna pasta bake, plain with pasta, topping for pizza, a sauce for chicken wrapped in cheese and bacon, spooned on a jacket potato with some cheese, as a sauce in veggie lasagne, as a sauce with meatballs…. I could go on!

It’s also great for turning leftovers into another meal, a little of this sauce warmed up and spooned over some chicken is our favourite way to use up leftover chicken!

1/2 onion chopped
2-3 cloves of garlic
2 tablespoons olive oil
3 tins chopped tomatoes
2 teaspoons sugar
1 tablespoon balsamic vinegar ( don’t worry if you dont have any in – it almost as nice without)
1 tablespoon dried basil

Don’t worry about measuring everything perfectly as this recipe is really forgiving and I’ve never made a bad batch despite the fact that I very rarely measure things properly.  You can also make larger quantities, I usually double everything so I have plenty to freeze as I use it so often!

As it’s a slow cooker recipe, it really is as simple as adding everything to the slow cooker and cooking on low for 6 – 8 hours stirring every couple of hours.

I’m organising my freezer at the moment so I have a batch of this bubbling away and I’ll be making some cheese sauce later as well!
