Ingredients

  • 1 head of cauliflower
  • 1/4 cup oil
  • 1/2 teaspoon salt
  • 1/4 teaspoon pepper
  • 1 shallot
  • 3 cloves of garlic
  • 3 cups low-sodium chicken stock
  • 1 cup heavy whipping cream

Instructions

  • Remove the stem from the cauliflower and cut it into chunks.
  • Combine the oil with the salt and pepper. Toss the cauliflower with the seasoned oil.
  • Put the seasoned cauliflower, peeled and cut shallot, and peeled garlic onto a sheet pan.
  • Roast the garlic in a preheated 425-F oven for 10-15 minutes or until it is golden brown.
  • In a large pot, simmer the chicken broth. Add the roasted cauliflower, shallot, and garlic, plus any pan juices, to the pot. Bring to a simmer and cook for about 10 minutes or until the cauliflower stems are very soft.
  • Remove from the heat and puree in a blender or with an immersion blender.
  • Add the cream and season with more salt and pepper if needed. Add extra cream or chicken broth to reach your desired thickness.
  • Serve topped with shredded sharp cheddar and chopped green onions. Enjoy!

Notes

Recipe Card Tips

  • Use fresh cauliflower, never frozen. Frozen cauliflower holds too much water to brown properly.
  • Skip red onion if you don't have shallots. It turns the finished soup an unappealing color.
  • Layer the flavor in order, broth first, then browned vegetables, then aromatics, then the cream at the end.
