Instructions
Instant Pot Method
- Prep ingredients: Measure and chop all ingredients. Combine in a large bowl to minimize cleanup.
- Preheat: Press saute button on Instant Pot and let inner pot heat up for 2 minutes.
- Sauté vegetables: Add all ingredients except water (onion, garlic, zucchini, bell pepper, green beans, eggplant, celery, carrot, potato, parsley, garbanzo beans, tomatoes, basil, oregano, black pepper, and salt). Sauté for 5 minutes, stirring regularly. Add small splashes of water if vegetables start to stick. This caramelization step adds depth to the flavor.
- Add liquid: Turn off Instant Pot. Add 3 cups water (or veggie broth) and stir.
- Pressure cook: Lock lid into place with steam nozzle in sealed position. Use manual setting (high pressure) and set timer for 10 minutes.
- Natural release: When time is up, allow pressure to dissipate naturally while leaving steam nozzle sealed. Once pressure is fully released and locking mechanism disengages, remove lid.
- Serve: Ladle into bowls and serve immediately, or allow to cool completely before storing in refrigerator.
Stovetop Method
- Prep ingredients: Measure and chop all ingredients.
- Preheat pot: Heat large pot over medium heat for about 2 minutes.
- Sauté vegetables: Add all ingredients except water (onion, garlic, zucchini, bell pepper, green beans, eggplant, celery, carrot, potato, parsley, garbanzo beans, tomatoes, basil, oregano, black pepper, and salt). Sauté for 5 minutes, stirring regularly. Add small splashes of water if anything starts to stick.
- Simmer: Add 4 cups water (or veggie broth) and stir. Place lid on pot at an angle and simmer for about 20 minutes, stirring occasionally, until vegetables are soft to your liking.
- Serve: Turn off heat and serve immediately.
Notes
- Storage: Refrigerate up to 5 days in airtight container; cool completely before storing
- Substitutions: Extremely flexible - swap vegetables based on what’s available, use pre-cut veggies for convenience, add veggie broth instead of water for richer flavor
- Tips: Don’t skip sauté step for caramelization; use natural pressure release for Instant Pot method
