Make this easy Tuscan Vegetable Soup with simple ingredients and big flavor. White beans, fresh vegetables, and herbs simmer into a comforting bowl that's ready in under 40 minutes.
In a large stock pot or dutch oven, preheat the olive oil on medium high heat for 1 minute. Then add the onion, carrot, celery and garlic. Using a spatula or wooden spoon, saute for about 3 minutes, until the vegetables start to soften.
Add the zucchini, thyme, oregano, salt and pepper and cook for another 3-4 minutes, stirring throughout. Add the broth and tomatoes and bring it to a boil, which will take about 5-10 minutes.
Reduce to low to simmer and add the beans and kale, and continue simmering for 5 minutes.
Serve hot and garnished with grated fresh parmesan cheese. Taste first, then add salt and pepper based on your preferences.
Notes
Dice all vegetables to a similar size (about ½-inch) for even cooking.
Sauté the aromatics first to build a flavorful base.
Add zucchini after the harder vegetables to prevent it from becoming mushy.
Bring soup to a boil before reducing to simmer.
Add kale in the last 5 minutes and remove from heat to keep it bright green.
Spinach can be substituted for kale; add in the last 2 minutes instead.
Great Northern or navy beans can replace cannellini beans.
Store leftovers in the refrigerator for up to 4 days.
Freezes well for up to 3 months.
Serve with crusty bread, garlic toast, or croutons, and top with Parmesan cheese.
