Step-by-Step Instructions
Step 1: Prepare the Vegetables
Wash and chop all vegetables into similar-sized pieces so they cook evenly. Dice the onion, slice the carrots and celery, cube the potatoes, chop the zucchini, trim the green beans, and shred the cabbage.
Preparation Time: 20 minutes
Step 2: Sauté the Aromatics
Heat olive oil in a large soup pot over medium heat (about 325°F/160°C if using an electric cooker).
Add:
- Onion
- Carrots
- Celery
Cook for 6–8 minutes, stirring occasionally until softened.
Add minced garlic and cook another 1 minute until fragrant.
Step 3: Build the Flavor
Stir in:
- Tomato paste
- Italian seasoning
- Oregano
- Thyme
Cook for 2 minutes while stirring constantly.
This step caramelizes the tomato paste and intensifies the soup’s flavor.
Step 4: Add the Broth
Pour in:
- Vegetable broth
- Diced tomatoes
Add:
- Potatoes
- Bay leaf
Bring everything to a gentle boil over medium-high heat (about 375°F/190°C).
Once boiling, reduce heat to low (around 200°F/95°C simmer).
Cover and simmer for 15 minutes.
Step 5: Add Remaining Vegetables
Add:
- Green beans
- Zucchini
- Corn
- Cabbage
Continue simmering for another 10 minutes.
Step 6: Finish the Soup
Stir in:
- Peas
- Spinach
Cook for 5 more minutes until the spinach wilts and all vegetables are tender.
Taste and season with salt and pepper.
Remove the bay leaf before serving.

Tips for Success
Don’t Overcook
Vegetables should remain slightly firm for the best texture.
Uniform Pieces
Cut vegetables into similar sizes for even cooking.
Layer Flavors
Cooking the herbs and tomato paste before adding liquid creates a deeper flavor.
Fresh Herbs
Fresh parsley added just before serving brightens the soup.
Adjust Thickness
For a thicker soup, mash a few cooked potatoes into the broth.

Storage Instructions
Refrigerator
Store cooled soup in an airtight container for up to 5 days.
Freezer
Freeze for up to 3 months.
Leave about one inch of space in containers because the soup expands as it freezes.
Reheating
Stovetop:
Heat over medium-low for 10–15 minutes, stirring occasionally.
Microwave:
Heat in 1-minute intervals, stirring between each interval until hot.
Make-Ahead Tips
Prepare all vegetables a day ahead and refrigerate them in sealed containers.
The soup tastes even better the next day as the flavors continue to develop.
If adding pasta or rice, cook and store it separately, then stir it into individual servings before reheating to prevent it from becoming overly soft.
Common Mistakes to Avoid
- Boiling the soup too vigorously, which can make vegetables mushy.
- Overcooking spinach or kale, causing dull color and texture.
- Forgetting to remove the bay leaf before serving.
- Adding delicate vegetables too early.
- Under-seasoning the broth—taste and adjust before serving.
