✏️Ingredient notes & substitutions

As mentioned, this soup is very customizable. All ingredients are suggestions, and we added our best substitutions to the notes.

  • Olive oil - Can use avocado oil for another vegan substitute. Butter or ghee can be used otherwise.
  • Onions & leeks - You can use just one or the other, or any onion you prefer.
  • Carrots & celery - Added with the onions and leeks.
  • Bell peppers & jalapeños - Can be substituted for any peppers you prefer. Any color bell pepper will work, and for the jalapeños, keep in mind that seeds add spice and they are optional.
  • Garlic - Freshly minced garlic is so tasty in this soup.
  • Seasonings - This soup is backed with dried spices and herbs. In addition to kosher salt and black pepper, we also used: garlic powder, onion powder, red pepper flakes, oregano, dried basil, smoked paprika, cayenne pepper, bay leaves, fresh thyme, and rosemary. You can use as much or as little as you want. You can also simply leave things out.
  • Zucchini - Cut into half moons.
  • Cabbage - We used green cabbage but you could use any type of cabbage you prefer, including Napa or purple cabbage.
  • Mushrooms - Anything you prefer. We used a mixture of sh*take and portabello mushrooms cut into slices.
  • Vegetable broth - You could substitute for beef or chicken broth if you're not vegan or vegetarian.
  • Crushed tomatoes - You could also use tomato paste or tomato sauce, but you will need to also add more liquid.
  • Lemon juice - Freshly squeezed for brightness and acidity.
  • Spinach, fresh parsley, cilantro, & green onions - You could use any leafy greens you like here, like kale, Swiss chard, or bok choy. Some other good herbs to use here would be basil.

🔪Prep work

  • It's a good idea to prep all of your ingredients ahead of time (anytime you're cooking really) but especially in this case! There are a ton of veggies in here, so having them all prepared and ready to add in easily at various stages is definitely the way to go.
  • Thinly slice your leeks, discarding the tough green tops. Place the leeks in a bowl of water and allow to sit for about 10 minutes. Leeks have many layers, so the dirt will need to be loosened up to be removed. Rinse the leeks thoroughly to ensure there's no leftover dirt.
  • Mince the garlic, thyme, and rosemary.
  • Dice onions, jalapeños, bell peppers, and celery.
  • Cut carrots into rounds. Slice mushrooms, and cut zucchini into rounds or half moons.
  • Cut cabbage into large pieces.
  • Juice the lemon.
  • Finely chop parsley and cilantro, and cut green onions into rounds.
  • Place all dry seasonings in a bowl. Place salt in its own bowl.

In a large dutch oven or stockpot over medium heat, add olive oil and sauté the leeks, onions, carrots, celery, jalapeños, and bell peppers with a large pinch of salt. Cook until softened for 7-10 minutes.

Once vegetables have softened, add in garlic, dried seasonings, fresh thyme, and rosemary. Cook until garlic is fragrant about 30 seconds.

Add in cabbage, zucchini, and mushrooms with more salt until the vegetables soften slightly, about 2-3 minutes.
