Preheat oven to 450°F. Halve Brussels sprouts. Arrange sprouts and cauliflower on a large sheet pan and drizzle with the olive oil. Roast for 15 min., stirring halfway.

Meanwhile, melt butter in a large sauce pan and sauté diced onion until translucent. Add the vegetable broth and bring to a boil. Simmer over low heat for 5 min.

Transfer half of the roasted vegetables to the broth and simmer for about 2 min., stirring occasionally. Return the remaining vegetables on the baking sheet to the oven, to roast for another 5 min.
