How to Make Roasted Vegetable Soup
- Preheat oven to 400 degrees F.
In a large mixing bowl, combine Brussels sprouts, carrots, onion, cabbage, celery, mushrooms and tomatoes. Do not add the spinach. Drizzle with olive oil and season with salt and pepper. Mix well. Spread on baking tray. Put in oven for 10 – 12 minutes or until lightly roasted.
In a large pot (8 to 10 quarts) or Instant Pot, add the mushroom broth or chicken broth, tofu, rosemary, thyme, garlic powder, salt, and pepper. Bring the broth to a simmer over medium high heat. If using an InstaPot, use the Sauté function on low.
As the broth begins to boil, add the vegetables (except for the spinach). If cooking in a pot, bring to a boil, then reduce heat to medium or medium and let simmer until vegetables are soft – about 35 – 40 minutes. If using an Instant Pot, set to Pressure Cook High for 21 minutes.
The soup is done when the vegetables are soft. Remove from heat and stir in the spinach just until it wilts.
Top with cheese, green onions, or bread if desired. Serve.

Some quick cooking vegetables to roast include tomatoes, summer squash, mushrooms, and kale. They will roast quickly, in 5 minutes.
