  • 1/4 teaspoon black pepper
  • 1 teaspoon thyme dried

Instructions

    Cup of Yum
  1. Line a large baking sheet with parchment paper. Prep your veggies if you haven’t already.
  2. Place all the vegetables, cut side down on the baking sheet (see pictures). Add the garlic all together in the middle of the baking sheet, else it will tend to brown and burn quickly. You can also just put a whole head of unpeeled garlic ( slice a small portion of end), drizzled with olive oil on the baking sheet.
  3. To a small bowl add the olive oil, salt, black pepper, thyme, and oregano and mix. Brush this all over the vegetables.
  4. Preheat the oven to 400ºF (206 c) and place the baking sheet in the oven to bake for 35-40 minutes. Check at the 25-minute mark and if needed brush some more olive oil on the vegetables.
  5. Also, check on the garlic if it’s golden. Depending on the size of the garlic cloves, they might be ready at this point or they might need another 5 minutes or so. When the garlic starts to get brown on some edges, remove the garlic and set aside.
  6. Bake for 5-10 minutes or longer depending on flavor preference( less or more fire-roasted/scorched flavor ). Remove the baking sheet from the oven and let the vegetables cool for 5-10 minutes then transfer to a blender along with the juices. If you baked the whole head of garlic then squeeze out the roasted garlic into the blender.
  7. Add 2 cups of water, cashews, and salt. Blend until the cashews are broken down and the mixture is really creamy. I usually blend for a minute, then let it sit for 5 minutes so the cashews can rehydrate, and then blend again for 30 seconds and repeat until the mixture is really creamy and the cashews have broken down completely.
  8. Transfer this soup to a saucepan, and add another 1/2 to 1 cup of water or more depending on the consistency you like. Bring to a good boil. Taste and adjust salt and flavor.
  9. I usually add more salt, black pepper, and some Italian seasoning as needed towards the end as the hot veggie volume initially drowns the salt and you can tend to oversalt .
  10. Let it simmer for another 3-4 minutes and take off the heat.
  11. Let the soup cool for 10 minutes before tasting again so the herbs have a chance to bloom. A really hot tomato soup will overshadow the herb flavor so you want to wait for the soup to cool slightly before tasting and adjusting the salt and herb flavor.
  12. You can also add pepper flakes or black pepper for garnish if you like and top the soup with some freshly chopped herbs and a little bit of vegan butter or non-dairy cream and serve with crackers or cornbread or grilled cheese sandwiches!
  13. Store refrigerated for upto 3 days and freeze for for upto 2 months

Notes

  • For a nut-free variation, replace cashews with pumpkin or hemp seeds, or use coconut cream or non-dairy yogurt.
  • Brush vegetables with olive oil and herbs to distribute flavors evenly during roasting.
  • Monitor garlic during roasting to avoid burning, removing when edges are golden brown.
