Substitutions & Variations

Soups are perfect for experimentation. If you want to change textures or flavors, try these ideas:

  • Clean out the fridge: Swap shallots for onion, or add zucchini, carrots, or sweet potatoes. Add more broth if you increase the vegetable amount.
  • Sweet potatoes: Use sweet potato in place of butternut squash if preferred.
  • Bell pepper colors: Yellow or orange peppers make for a slightly different, bright flavor without changing the method.
  • Spice it up: Increase red pepper flakes, add paprika, or a pinch of cayenne for more heat.

If you try other variations, adjust liquid and seasoning to taste and enjoy experimenting.
