1-First Step: Prepare the Ingredients Begin by chopping 1.5 kg of courgettes and peeling 4 shallots, then halve them for even roasting. Place these in a large roasting pan along with 1 whole garlic bulb, 4 sprigs of fresh thyme, and 20 g of fresh basil leaves. This initial setup ensures all elements mix well and develop flavors together, taking about 10 minutes of prep time.

2-Second Step: Season and Roast Drizzle the vegetables with 4 tbsp of olive oil and season generously with salt and pepper. Roast everything in the oven at 190°C for 45-50 minutes until the veggies turn soft and caramelized. This step enhances the natural sweetness of the courgettes and adds depth, making it a key part for a tasty roasted courgette soup; adapt by checking earlier if your oven runs hot.

3-Third Step: Process the Roasted Ingredients Once done, squeeze out the flesh from the roasted garlic bulb and remove the thyme sprigs to avoid woody bits. Transfer all the roasted courgettes, shallots, basil, and garlic to a blender. For a smoother version, add these after cooling slightly for better blending results, which suits dietary tweaks like a chunkier texture for kids.

4-Fourth Step: Blend with Stock and Cream Pour in 1 litre of vegetable stock and blend until the mixture is smooth. Then, add 200 ml of creme fraiche and blend again until creamy, adjusting as needed for vegans by using a plant-based alternative. This roasted courgette soup step ensures a velvety consistency, and you can taste and season more if required for personal preferences.

5-Final Step: Serve and Enjoy Serve the soup hot, drizzling extra creme fraiche on top for a finishing touch. The total time is about 55 minutes, with 45 minutes of cooking, making it perfect for quick meals. For variations, consider topping with herbs or pairing it with a similar vegetable-based chowder for a full meal, enhancing the experience for food enthusiasts.
