A tasty tomato pasta sauce cooked in the slow cooker and packed with five different hidden veggies. Perfect for fussy eating kids!

For years I’ve been making this Hidden Veg Tomato Sauce but I wanted to try a new and different version, cooked in the slow cooker so that I don’t have to stand over the hob while it simmers away.
My kids might be a little older now but it can still be a struggle to get them to eat a variety of veggies. But blending them all up into a simple tomato sauce still works wonders.
The vegetables I’ve used in this recipe are carrots, celery, courgette, red pepper and cauliflower.
I used packets of diced frozen cauliflower. I love having them in the freezer ready to pop straight into pasta sauces. But you can use fresh diced cauliflower too.
Also in the slow cooker goes a jar of passata, some water, a stock pot and dried oregano.
Cook on high for about 3.5 hours or low for 5 hours until the veggies are soft.
Then blitz with a hand blender until the sauce is completely smooth.
This sauce is brilliant to batch make and keep in the fridge or freezer. It will keep for 3 days in an airtight container or jar in the fridge or up to 3 months in the freezer, ready to have on hand for a speedy dinner for the kids.
Aswell as a pasta sauce, this also works really well as a pizza sauce or used to make Cheese & Tomato Quesadillas.
