Preheat your oven to 400°F (200°C).
Chop the mixed vegetables into bite-sized pieces.
Toss the vegetables with olive oil, salt, pepper, thyme, and paprika.
Spread the vegetables evenly on a baking sheet.
Roast in the oven for 20-25 minutes or until tender and slightly caramelized.
While vegetables are roasting, heat a pot over medium heat.
Add chopped onion and minced garlic; sauté until soft.
Once roasted, add the vegetables to the pot.
Pour in the vegetable broth and bring to a simmer.
Use an immersion blender to puree until smooth (or blend in batches).
Adjust seasoning if necessary and serve warm.
