How to Make

- Step 1: Score the top of the tomatoes

- Step 2: Drop into boiling water for a few minutes until skins loosen, then peel. Remove most seeds and finely chop the flesh.

- Step 3: Drizzle a frying pan over a medium high heat with the olive oil. Fry onion, celery and garlic until softened.

- Step 4: Add the tomatoes and cook for a few minutes, breaking up any large pieces. Stir in torn basil, balsamic vinegar, salt and pepper, then simmer on low for 45–60 minutes until rich and deep red.

- Step 5: You can add a little stock if you prefer a more watery sauce, but I love the thickness and flavour of this sauce just as it is.

- Step 6: This sauce is delicious served over pasta with a little grating of parmesan (optional)
Tips & Variations
Want to mix things up a little? Here are some easy ways to tweak the sauce depending on what you’ve got on hand – or the mood you’re in:
- No fresh tomatoes? You can substitute with a couple of tins of quality plum tomatoes in a pinch, but the flavour of ripe fresh tomatoes really shines here.
- Add a bit of heat – a pinch of chilli flakes gives this sauce a warming twist.
- Creamy twist – swirl in a spoonful of cream cheese, ricotta, crème fraîche for a velvety finish.
- Want it smoother? Blend it with a stick blender once cooked down. You might want to add in some flavoured stock for this method.
How I Like to Use It
Once you’ve made this sauce, the possibilities are endless. Here are just a few of my favourite ways to enjoy it:
- Batch it – double or trip the recipe, cool and freeze in portions for quick meals later.
- Pasta night – toss with spaghetti, penne, or gnocchi.
- Meat dishes – spoon over grilled chicken, meatballs, or steak.
- Base sauce – perfect for bolognese, lasagne, pizza, or even a chilli con carne.

Tomato and Basil Sauce
Make the most of ripe tomatoes with this easy, vibrant Tomato and Basil Sauce that’s bursting with fresh, garden flavours.
Ingredients
- 7 large tomatoes (I used vine or roma tomatoes)
- 1 onion, finely chopped
- 2 celery stalks, finely chopped
- 3 garlic cloves, crushed
- 1 tablespoon of olive oil
- 2 tablespoons of tomato paste (puree)
- Splash of balsamic vinegar
- Handful of fresh basil leaves
- pinch of salt and pepper (to taste)
Instructions
- Prep the tomatoes: Score a small cross in the tops of each tomato. Drop into a saucepan of boiling water for a few minutes until the skins begin to loosen. Remove, allow to cool slightly, then peel off the skins.
- Remove seeds: Cut the tomatoes and scoop out as many seeds as you can. Finely chop the remaining tomato flesh.
- Cook the base: Heat olive oil in a large frying pan over medium-high heat. Add the onion, celery, and garlic. Sauté until softened, around 5–7 minutes.
- Add the tomatoes: Stir in the chopped tomatoes and cook for a further few minutes, breaking up any large pieces with the back of a wooden spoon.
- Flavour and simmer: Stir in the tomato paste, splash of balsamic, torn basil leaves, and season with salt and pepper. Reduce heat to low and simmer gently for 40-45, until thickened and rich in colour.
- Adjust texture if needed: If you prefer a thinner sauce, add a splash of vegetable stock or water. You can also blend it smooth, but we love it left fresh and chunky for a more rustic feel.
- Serve or store: Use immediately or cool and store in the fridge (up to 5 days) or freezer.
