Ingredients

2 tablespoons olive oil
1 large yellow onion, diced
3 cloves garlic, minced
2 medium carrots, sliced
2 celery stalks, sliced
1 red bell pepper, diced (optional but recommended)
2 cups diced Yukon gold potatoes (or sweet potatoes)
1 zucchini, diced
1 cup green beans, trimmed and cut into 1-inch pieces
1 (14.5 oz) can diced tomatoes with juices
6 cups low-sodium vegetable broth
1 (15 oz) can cannellini or chickpeas, drained and rinsed
2 cups chopped kale or baby spinach
1 teaspoon dried thyme
1 teaspoon dried oregano
1 bay leaf
1/2 teaspoon smoked paprika (optional but stellar)
1/4–1/2 teaspoon red pepper flakes (to taste)
Salt and black pepper, to taste
1–2 tablespoons lemon juice or red wine vinegar
Fresh parsley or basil, chopped (for garnish)
Parmesan rind (optional; adds umami if not vegan)

Let’s Get Cooking – Instructions

Build your flavor base: Heat olive oil in a large pot over medium heat. Add onion, carrot, and celery with a pinch of salt.
Cook 5–7 minutes until softened and slightly golden. Add garlic and bell pepper; cook 1 minute until fragrant.
Spice it right: Stir in thyme, oregano, smoked paprika, and red pepper flakes. Toast 30 seconds to bloom the spices.
Don’t skip this — it’s where the flavor wakes up.
Load the pot: Add potatoes, zucchini, green beans, diced tomatoes (with juices), and broth. Drop in the bay leaf and the Parmesan rind if using. Stir, scrape up any browned bits, and bring to a gentle boil.
Simmer to tender: Reduce heat to medium-low and simmer 15–20 minutes, until potatoes are fork-tender.
Taste the broth; add salt and pepper as needed.
Add protein and greens: Stir in the beans and kale/spinach. Simmer 3–5 minutes more until greens are wilted and beans are warmed through.
Finish with acid: Remove bay leaf (and rind). Stir in lemon juice or vinegar.
Taste again and adjust salt, pepper, and heat level. The brightness should make the flavors pop.
Serve and flex: Ladle into bowls, top with chopped parsley or basil. Add a drizzle of olive oil or a sprinkle of grated Parmesan if you’re not keeping it vegan.
Crusty bread on the side? Obviously.

Storage Instructions

Fridge: Cool completely, then store in airtight containers for up to 5 days. Flavor improves overnight — science and magic.
Freezer: Portion into freezer-safe containers, leaving headspace.
Freeze up to 3 months. Thaw in the fridge overnight, then reheat gently.
Reheating: Stovetop over medium or microwave in bursts, stirring. Add a splash of water or broth if it thickens.
Pro tip: If you plan to freeze, slightly undercook the potatoes and greens so they hold texture later.

Nutritional Perks

High fiber, low nonsense: Veggies and beans deliver fiber that keeps you full and supports gut health.
Micronutrient party: Vitamins A, C, K, folate, potassium, and iron from the mixed veg and greens.
Plant-powered protein: Beans add 7–9 grams of protein per serving, making this a real meal, not a side quest.
Heart-healthy fats: Olive oil provides monounsaturated fats.
Keep it light or add a touch more for richness.
Calorie smart: About 220–300 calories per bowl (depends on portions and add-ins). Satisfying without the food coma.

Pitfalls to Watch Out For

Skipping the acid: Without lemon or vinegar, the soup tastes flat. Add it at the end and thank me later.
Overcooking the veg: Mushy potatoes and sad greens are a vibe killer.
Test doneness; pull it as soon as they’re tender.
Under-salting the broth: Low-sodium broth needs seasoning. Salt in layers and taste as you go (IMO, this is the secret).
Dumping all veg at once: Faster isn’t better. Stagger additions so delicate veg don’t disintegrate.
Forgetting texture: A quick smash of a few potatoes or beans against the pot wall thickens the broth naturally.
Try it if your soup feels too thin.

Different Ways to Make This

Italian-ish minestrone: Add 1 teaspoon Italian seasoning, a handful of small pasta in the last 10 minutes, and finish with basil and Parmesan.
Mediterranean spin: Use chickpeas, add 1/2 teaspoon cumin and coriander, finish with lemon zest and parsley.
Smoky Southwest: Swap diced tomatoes for fire-roasted, add corn and black beans, bump smoked paprika, and finish with lime and cilantro.
Gingery miso vibe: Sauté 1 tablespoon grated ginger with garlic, use veggie broth plus a strip of kombu, finish off-heat with 1–2 tablespoons white miso. Add tofu cubes and spinach.
Creamy (dairy-free): Blend 2 cups of the soup and stir back in, or add 1/2 cup coconut milk at the end for silky richness.
Protein boost: Add cubed cooked chicken, turkey, or plant-based sausage. Or toss in lentils at the simmer stage (add 10–15 minutes).

FAQ

Can I make this in a slow cooker?

Yes.

Sauté onions, carrots, celery, garlic, and spices on the stove first for flavor. Transfer to a slow cooker with potatoes, tomatoes, beans, green beans, and broth. Cook on Low 6–7 hours or High 3–4.

Add zucchini and greens in the last 30 minutes. Finish with lemon or vinegar.

What if I don’t have all the vegetables listed?

No problem. Use 6–8 cups of mixed vegetables total.

Great swaps: leeks for onion, parsnips for carrots, sweet potatoes for Yukon golds, peas for green beans, or cabbage for kale. The method stays the same.

How do I make it gluten-free and vegan?

It already is gluten-free and vegan as written if you skip the Parmesan rind and topping. Just check your broth label for hidden gluten and choose vegan garnishes.

How can I thicken the soup naturally?

Mash some potatoes or beans against the side of the pot and stir.

Alternatively, blend 1 cup of the soup and return it to the pot. Instant body, no flour needed.

Can I add grains or pasta?

Absolutely. Add 1/2 cup small pasta, farro, barley, or rice during simmering; adjust liquid as needed.

For best texture, cook pasta separately and add to bowls so it doesn’t soak up all the broth in the fridge.

Why add acid at the end?

Acid brightens and balances the savory flavors. Heat can dull acidity over time, so finishing with lemon or vinegar ensures that clean, fresh pop.

What’s the best broth to use?

A good low-sodium vegetable broth lets you control salt. If you have homemade stock, flex it.

For extra umami, add a Parmesan rind, a dash of soy or tamari (FYI: not gluten-free unless tamari), or a teaspoon of tomato paste during the sauté.
