Oven Roasted Tomato Soup: Easy & Delicious

There's something enormously comforting about a bowl of hot soup on a cold and rainy afternoon. This easy and delicious Oven Roasted Tomato Soup blends the fabulous flavours of garden fresh basil, garlic, onions and oven roasted tomatoes for a luxuriously smooth soup that's full of rich Italian flavours. Slow roasting caramelizes and intensifies the flavour of the tomatoes, enhances their natural sweetness, and lends extraordinary depth to this hearty and satisfying soup — ideal with a hot grilled cheese sandwich! Once roasted, these rich red tomatoes end up sweet and concentrated, not entirely dissimilar from sun-dried tomatoes but so much better. They can also be used in so many different ways, from adding them to a pasta dish, savoury tart, classic quiche, sumptuous strata, or as part of a simple crostini with brie, pesto, ricotta or tapenade — the possibilities are endless.

then placed in one layer on a foil lined baking sheet

Roasted at 400°F for 45 minutes, the tomatoes become soft, lightly caramelized

Then the oven roasted tomatoes and their liquid are added 

and the mixture is simmered for 45 minutes

After 45 minutes, the soup has become much richer and aromatic

Using a hand immersion blender, the soup is puréed until smooth, 

with a dash of cream at the end for added richness
