Fresh tomatoes are simmered into a tangy, vibrant red hot pot base. This healthy, vegetarian family broth is low calorie, fresh, and a lighter alternative to spicy hot pot.
Heat olive oil in a large stockpot over medium heat. Add chopped onions, celery, and carrots, and sauté for 5 minutes until softened and lightly golden.
Add minced garlic and cook for 1 minute, stirring often to avoid burning.
Roughly chop the tomatoes and add them to the pot. Stir well and let them cook for 5–7 minutes on medium-high, occasionally pressing the tomatoes with a spoon.
Pour in the water, then add salt, black pepper, and sugar. Bring to a gentle boil over high heat, then immediately reduce to a low simmer.
Cover and simmer for 30–40 minutes, stirring every 10 minutes to prevent sticking and help tomatoes break down fully.
Taste and adjust seasoning if needed. For a smooth broth, strain or blend as desired. Serve hot as the base for hot pot with your favorite add-ins.
