How to Make Vegetarian Cabbage Soup
Step #1: Place the agar-agar in a medium saucepan along with 3 cups of water until hydrated (about 5 minutes). Meanwhile, place the garlic and mushrooms in the bowl of a food processor and pulse until finely minced.
Step #2: Once the agar has hydrated and “bloomed,” set the saucepan over medium-high heat and allow it to come to a full boil. Boil for 5 minutes, then turn the heat down to low.
Step #3: Heat the olive oil in a 6-quart or larger Dutch oven (or other lidded pot) over medium heat. Add the onions and carrots; sauté for 4 to 5 minutes, until they begin to soften. Push the onions and carrots to one side of the pot and add the mushroom-garlic mixture to the pan. Allow to cook, undisturbed, for 1 to 2 minutes, until browned. Mix the mushroom mixture with the carrots and onions. Add the cabbage, broth, tomatoes, rice, salt, pepper, paprika, and bay leaves to the pot. Stir in the warm agar-agar mixture.
Step #4: Allow the pot to reach a boil over medium heat. Once it has reached a boil, turn the heat down to low and cover the pan. Simmer for 15 to 20 minutes, until the rice is cooked through.
Step #5: Stir in the honey, vinegar, and half of the parsley. Taste and add salt and pepper as needed. Serve garnished with remaining parsley leaves.

Expert Tips
- Pre-Sauté Mushrooms: Before adding them to the food processor, lightly sauté the mushrooms in a bit of olive oil to enhance their flavor and reduce the moisture content.
- Deglaze the Pot: After sautéing the mushroom-garlic mixture, deglaze the pot with a splash of the broth to lift any browned bits from the bottom of the pot for extra depth of flavor.

Frequently Asked Questions

NOTES
Nutrition














Hi- if you choose not to use the agar-agar powder would you need to add extra liquid (i.e. 3 cups of water that was used to bloom the powder) ??
Hi Jill,
Yes, you would still need some water. I suggest you start with 1 1/2 cups and add up to another 1 1/2 cups as needed for the right consistency for you.
