How to Make Roasted Vegetable Soup
Step 1: Preheat the Oven
Preheat your oven to 200°C (390°F). This temperature will help achieve that perfect caramelization on your vegetables.

3. Season with salt, pepper, and sprinkle in the dried sage and Italian herbs. Toss until evenly mixed.
Step 3: Roast the Vegetables
Spread the seasoned vegetables evenly on a baking sheet:
1. Roast in the preheated oven for about 30–35 minutes until tender and caramelized.
2. Halfway through roasting, turn the vegetables for even cooking.
Step 4: Blend the Soup
Once roasted:
1. Transfer everything from the baking sheet into a large pot.
2. Add in the vegetable stock, along with any reserved garlic (squeeze out of skins).
