HIDDEN VEG TOMATO SAUCE
Ingredients
- 1 tbsp olive oil
- 2 onions
- 1 leek
- 2 celery sticks
- 2 courgettes
- 1 red bell pepper
- 2 carrots
- 2 medium sweet potatoes
- 3 garlic cloves
- 1 red chilli optional
- 1 tbsp Italian mixed herbs
- 2 tins chopped tomatoes
- 2 tbsp Balsamic Vinegar optional
- 2 tbsp Sugar optional
Instructions
Prepare the Vegetables
- Start by chopping all your vegetables into roughly 1cm pieces. Don’t worry about perfection here — everything will be blended later.
- Roughly chop the garlic and chilli.
- Tip: Keeping the pieces similar in size helps everything cook evenly.
Soften the Vegetables
- Heat the olive oil in a large pan over a medium heat.
- Add all the chopped vegetables (except the tinned tomatoes) and give everything a good stir so they’re coated in the oil.
- Cook for about 15 minutes, stirring every few minutes to stop anything catching on the bottom.
- What to look for: The vegetables should start to soften, shrink slightly, and smell fragrant. The onions will turn translucent and everything will look glossy.
Build the Sauce
- Add the chopped tomatoes to the pan.
- Fill one of the empty tins with water and pour it in, then repeat with the second tin (this helps rinse out all that tomato goodness and gives you a nice sauce consistency).
- Stir well and bring everything to a gentle boil.
Simmer and Develop Flavour
- Reduce the heat and let the sauce simmer gently for about 20 minutes.
- Stir occasionally to stop it sticking.
- What to look for: The vegetables should be very soft, and the sauce will start to thicken slightly and deepen in colour.
Blend Until Smooth
- Remove the pan from the heat and carefully blend the sauce using a stick blender until smooth.
- Take your time and keep the blender fully submerged to avoid splashes.
- Tip: The sauce will be hot, so blend slowly and carefully.
Final Taste & Adjust
- Taste the sauce and season with salt and pepper as needed.
- If you like, add:, A splash of balsamic vinegar for depth and A pinch of sugar to balance the acidity
- Stir well and adjust to your taste.
Serving Suggestions
- Use straight away with pasta, meatballs, or in a Bolognese.
