Ingredients
- 1.5 lb cauliflower, cut into florets
- 4 tbsp olive oil, divided
- 1 medium onion, diced into 1/2-inch cubes
- 3 clove garlic cloves, minced
- 4 cups vegetable broth
- 1 tsp salt
- ½ tsp black pepper
- 2 tbsp fresh herbs (parsley, dill, or chives, chopped)
Instructions
- 1
Set the oven to 425°F and wait until the indicator light or beep tells you it has finished heating, about 10 minutes.
- 2
Pat the cauliflower florets dry with a clean kitchen towel, pressing gently to remove surface moisture so they roast instead of steam.
- 3
Place the cauliflower on a large rimmed sheet pan, drizzle with 2 tablespoons of olive oil, sprinkle with 0.5 tsp salt and 0.25 tsp pepper, and toss with your hands until every piece is lightly coated.
- 4
Spread the cauliflower in a single layer on the sheet pan and slide it into the oven for 20–25 minutes, stirring once halfway through, until the florets are deep golden brown with crispy edges.
- 5
While the cauliflower roasts, place a large pot over medium heat and wait 30 seconds until the pot feels warm when you hold your hand 2 inches above it.
- 6
Pour 2 tablespoons of olive oil into the warm pot, tilt to coat the bottom evenly, and wait 30 seconds for it to heat through.
- 7
Add the diced onion and stir constantly with a wooden spoon for 5 minutes until the pieces are soft and translucent, scraping the bottom so nothing sticks.
- 8
Add the minced garlic and stir continuously for 60 seconds until the kitchen smells strongly fragrant and the garlic loses its raw white color.
- 9
Carefully remove the hot sheet pan from the oven using oven mitts and pour the roasted cauliflower directly into the pot with the aromatics.
- 10
Pour in 4 cups of vegetable broth and bring the mixture to a gentle boil over medium-high heat, about 5 minutes—you'll see large bubbles breaking the surface.
- 11
Turn the heat to medium-low and let the soup simmer gently for 5 minutes so the flavors meld, stirring once.
- 12
Carefully pour the soup into a blender in batches (fill no more than halfway each time to avoid splashing hot liquid), cover the lid tightly with a folded kitchen towel, and blend on high for 60 seconds until completely smooth.
- 13
Pour the blended soup back into the pot, add the remaining 0.5 tsp salt and 0.25 tsp pepper, and stir once to distribute.
- 14
Ladle the soup into bowls and scatter 0.5 tbsp of fresh chopped herbs over the top of each bowl just before serving.
