“This is a great homemade sauce to use as a pizza base or to smother your meatballs. See my Keto Cabbage and Mince Rolls where I used the full batch. The recipe yields a 500g / 17.6oz batch and the macros have been calculated that one person’s serving will be approximately 125g / 4.4oz. This is enough for 4 people. If you don’t need it all, it freezes well. Don’t forget the all-important dried oregano which adds an authentic Italian flavour.” – Monya

More on Roasted Tomato Sauce…

One of the most significant advantages of roasting tomatoes is the concentration of their natural sweetness and umami flavour. As the tomatoes bake in the oven, their natural sugars caramelize, resulting in a savoury-sweet taste that can elevate the taste. This enhanced flavour can reduce the need for added salt or sugar in recipes, promoting overall health.

Nutritionally, tomatoes are a powerhouse of vitamins and antioxidants. They are particularly rich in vitamin C, which is essential for a healthy immune system and collagen production. Additionally, they provide a significant dose of vitamin A, which supports eye health and skin maintenance.
 
Tomatoes are also a good source of lycopene. Lycopene is an antioxidant known for its potential to reduce the risk of certain chronic diseases, including heart disease and certain types of cancer.
 
Moreover, the cooking process of roasting tomatoes doesn’t diminish their nutritional value. In fact, roasting tomatoes can even increase the availability of some nutrients, making them more beneficial for our bodies.
 

It is important to note that to maintain ketosis, it’s essential to track carbohydrate intake and ensure it aligns with your daily macro goals.

Per serving

Calories: 67kcal | Carbohydrates: 7.7g | Protein: 1.4g | Fat: 3.4g

Equipment

• kitchen scale
• sharp knife
• universal measuring spoons
• baking tray
• electric hand blender

Ingredients

• 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)

Instructions

• 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.
