Roasted Tomato Sauce (Keto)

Roasted Tomato Sauce

This is a great homemade sauce to use as a pizza base or to smother your meatballs over courgetti. (See my Low-carb Cabbage and Mince Rolls where I used the full batch.) The recipe yields a 500g / 17.6oz batch which will sufficiently feed 4 people as a ‘pasta’ sauce. (The macros have been calculated that one person’s serving will be approximately 125g / 4.4oz.) If you don’t need to use it all, you can freeze the remaining in handy batches. Don’t forget to stir in some dried oregano for an authentic Italian flavour.

Prep Time 15 minutes
Cook Time 1 hour
Total Time 1 hour 15 minutes
Servings 2 cups approx.


  • 2 large cloves garlic, unpeeled
  • 1 tsp olive oil
  • 1 kg (2.2 lb) organic tomatoes, (approx. 10)
  • 1 TB olive oil, additional
  • 1 TB white wine vinegar
  • salt and freshly ground black pepper
  • pinch dried oregano, (optional)


  • Preheat the oven to 160°C (fan oven). This is 180°C for conventional ovens (or 350°F / gas mark 4).
  • Place the unpeeled garlic cloves onto a piece of aluminium foil. Drizzle over the teaspoon olive oil and wrap up tightly, ensuring the little foil parcel is sealed air-tight (make sure the skin of each clove is intact.)
  • Halve the tomatoes and spread out on a roasting tray. Drizzle over the tablespoon olive oil and toss well to evenly coat. Add the garlic foil parcel to the tray.
  • Bake in the oven for 1 hour.
  • Remove and tip into a bowl or pan. Add the white wine vinegar. Open up the little foil parcel of roasted garlic. Once the cloves are cool enough to handle, slice off the top end of each and slide out the roasted puree.
  • Use a hand blender to blitz the mixture well. Season with salt and freshly ground black pepper. (Add a pinch of dried oregano for an authentic Italian flavour.)
  • Set aside to use as a pizza base sauce or 'pasta' sauce over your meatballs and courgetti.


A new-and-improved version of this delicious recipe features in my new cookbook KETO KITCHEN - currently available to pre-order on Amazon worldwide. (For UK readers, it will also be available at Waterstones.)
