The Story Behind This Recipe

Roasting the tomatoes before blending concentrates their sweetness and flavour, giving the soup a depth that raw tomatoes simply cannot match.

A comforting, velvety bowl with no cream needed, low in calories and packed with antioxidants (lycopene).

Preparation Steps

  1. Roast the tomatoes

    Preheat the oven to 200 °C. Spread the tomatoes, garlic and onion on a baking tray, toss with olive oil, salt and pepper, and roast for about 35 to 40 minutes until charred and concentrated. Roasting intensifies the natural sweetness of the tomatoes.

  2. Simmer

    Transfer the roasted vegetables to a saucepan, add the vegetable stock and simmer gently for about 10 minutes until the flavours meld, then stir in most of the basil.

  3. Blend

    Blend the soup until completely smooth and velvety. Thorough blending gives a creamy texture without any cream.

  4. Adjust the seasoning

    Taste and adjust salt and pepper, adding more stock if you prefer a thinner consistency. Tasting ensures the right balance of acidity and seasoning.

  5. Serve

    Serve the soup warm, garnished with fresh basil and a drizzle of olive oil. A deeply flavoured roasted tomato soup.

Blood Sugar Impact

The glycemic index (GI) measures how quickly a food raises blood sugar, while the glycemic load (GL) measures how much a full serving raises it. Together they give the complete picture.

Glycemic Index

GI
10 Low

A low value (≤55) means a gradual rise in blood sugar — the most suitable range for diabetes and insulin resistance.

Glycemic Load

GL
2 Low

Glycemic load reflects the impact of the full serving. To lower it: take half a serving, or pair the recipe with a source of protein and fiber.

Troubleshooting

The most common problems when preparing Roasted Tomato and Basil Soup, and how to fix them:

The protein / meat is dry

The heat was too high or the cooking time too long. Roast at medium-high heat for a defined time, and let the meat rest for several minutes before slicing so the juices return.

No grill marks appear

The pan was not hot enough, or the surface was wet. Heat the grill pan well and pat the surface dry. Do not move the piece before the marks form.

Flat, one-dimensional flavour

Not enough salt or seasoning. Season well and taste, then add a fresh herb or a squeeze of lemon to lift all the flavours.

Storage and Make-Ahead

Refrigerator (4 °C)

Two days in an airtight container once cooled. Reheat thoroughly before serving.

Freezer (−18 °C)

One to two months in individual portions. Thaw in the fridge before reheating.

Prep ahead

Prepare and chop ingredients in advance and keep refrigerated; assembly and cooking then takes only minutes at serving time.

Reheating

Reheat gently with a splash of water or in a moderate oven until hot through. Do not leave out of the fridge for more than two hours [2].

Frequently Asked Questions

Is this dish suitable for people with diabetes?
Yes — its glycaemic index is low and the protein and fibre slow sugar absorption. Stick to a moderate portion, serve alongside vegetables or a salad, and avoid large amounts of white starchy sides.
How do I store leftovers?
In an airtight container in the fridge for a few days, or in the freezer for later portions (except salads and seafood dishes which have a shorter shelf life). Reheat thoroughly once only.
Can I adapt it to fit my diet?
Yes — see the substitutions table: you can swap the protein, make it dairy-free or gluten-free, or reduce the salt and fat without losing flavour.
