These ingredients are simple, fresh, and thoughtfully chosen so each veggie adds something special to the soup’s texture, color, and flavor. Every component plays a role in building a rich, wholesome vegetable medley that tastes like it simmered for hours, even though it’s ready in under an hour.

Olive oil: Provides a smooth, fruity base to sauté the aromatic vegetables.
Yellow onion: Adds sweetness and depth when softened.
Garlic: Brings a fragrant, warm undertone that lifts the entire soup.
Carrots: Offer natural sweetness and vibrant orange color.
Celery: Adds subtle crunch and a fresh, herbal note.
Zucchini: Softens beautifully and absorbs flavors while adding tenderness.
Green beans: Contribute a gentle bite and bright green hue.
Diced tomatoes: Bring acidity, moisture, and richness.
Vegetable broth: The flavorful liquid base that ties everything together.
Dried oregano, basil, thyme: These classic Italian herbs enhance the soup’s aromatic qualities.
Frozen peas: Add a pop of sweet freshness near the end of cooking.
Baby spinach: Provides vibrant greenery and delicate texture.
Salt and freshly ground black pepper: Essential for seasoning and balancing flavors.
Fresh parsley: Gives a final touch of brightness and color just before serving.

Directions

Step 1: Heat the olive oil in a large pot over medium heat until shimmering, which takes about 1 to 2 minutes.

Step 2: Add the diced onion to the pot, cooking for 3 to 4 minutes while stirring occasionally, until the onion becomes soft and translucent.

Step 3: Stir in the minced garlic and cook for about 30 seconds until fragrant, being careful not to let it brown.

Step 4: Add the carrots, celery, zucchini, and green beans. Cook, stirring every couple of minutes, for 5 minutes to start softening these vegetables.

Step 5: Pour in the canned diced tomatoes with their juices, then add the vegetable broth. Stir in the dried oregano, dried basil, and dried thyme.

Step 6: Increase the heat to medium-high and bring the soup to a gentle boil. Once boiling, reduce the heat to low, cover the pot, and let it simmer for 15 to 20 minutes until all the vegetables are tender.

Step 7: Remove the lid and stir in the frozen peas and baby spinach. Let the soup simmer uncovered for another 3 to 5 minutes until the peas are heated through and the spinach has wilted.

Step 8: Season with salt and freshly ground black pepper to your preferred taste. Stir in the chopped fresh parsley right before ladling into bowls.

Step 9: Serve the soup hot and enjoy! Any leftovers should be stored in the refrigerator and gently reheated on the stovetop.

Servings and Timing

This recipe makes about 6 hearty servings, perfect for a family meal or for leftovers the next day. Prep time is roughly 10 minutes, mostly for chopping the veggies, while the active cooking time is around 35 minutes, including sautéing and simmering. Total time from start to finish comes to approximately 45 minutes. There’s no extra resting time needed, so you can jump right into serving as soon as it’s done simmering.

How to Serve This One-Pot Vegetable Soup Recipe

A deep bowl filled with creamy beige soup forms the base layer, topped with several browned slices of mushrooms that add dark brown and textured detail. Thin, light yellow slices of squash sit in the middle, some standing vertically to create height, and are garnished with small green herb leaves. Thin strands of grated cheese are scattered lightly across the top, adding white flecks and strands. In the background, blurred slices of dark brown bread and white boiled egg pieces rest on a wooden board, all set on a white marbled surface. photo taken with an iphone --ar 4:5 --v 7

I love serving this soup piping hot straight from the pot, ladled into your favorite deep bowls. It’s wonderful on its own for a light meal but becomes even better when paired with crusty bread, like a rustic sourdough or garlic baguette, perfect for dipping into the broth. Another great side is a simple green salad tossed with lemon vinaigrette to keep things fresh and bright alongside the warm soup.

For presentation, I like sprinkling a bit more fresh parsley on top or even some shaved Parmesan to add a subtle salty richness. If I’m feeling fancy, a drizzle of good olive oil or a dollop of pesto accents the soup beautifully and makes it look inviting for guests. When it comes to drinks, a crisp white wine like Sauvignon Blanc or a light herbal tea pairs perfectly, complementing the herbal notes in the soup without overpowering it.

This soup shines in so many occasions—from cozy weeknight dinners to casual weekend lunches and even as a starter for holiday meals. I usually recommend serving it hot to bring out those comforting flavors, but it also keeps well if you want to enjoy it warm or at room temperature the next day. Portion sizes around one to one and a half cups per person strike a great balance, especially if you’re adding sides.

Variations

One of the things I enjoy most about this One-Pot Vegetable Soup Recipe is how adaptable it is. If you want to change up the veggies, feel free to swap the green beans for asparagus or add some diced potatoes for extra heartiness. For a different flavor profile, try adding a pinch of smoked paprika or a splash of soy sauce for an umami touch.

If you’re following specific dietary needs, this recipe is naturally vegan and gluten-free, which I love. To make it even more protein-packed, I sometimes toss in cooked lentils or chickpeas during the simmering stage. For a creamier texture, stirring in a splash of coconut milk or a dollop of cashew cream near the end is divine and adds a lovely richness without dairy.

Lastly, while I mostly prepare this soup on the stove, you can also make it in a slow cooker by layering the ingredients and cooking on low for 4 to 6 hours, or use an Instant Pot on the soup setting for even quicker prep. Both methods are excellent and produce deep, melded flavors that I find incredibly satisfying.

Storage and Reheating

Storing Leftovers

I usually store leftover soup in airtight glass containers or BPA-free plastic containers in the fridge. It keeps well for about 3 to 4 days. I recommend letting the soup cool fully before sealing the container to maintain freshness and prevent condensation from altering the texture.

Freezing

This soup freezes beautifully, making it my go-to for meal prep or when I want to stash some comfort food for later. I portion it into freezer-safe containers or heavy-duty freezer bags, leaving some headroom for expansion. You can keep it frozen for up to 3 months. To thaw, transfer the soup to the fridge overnight for gentle defrosting before reheating.

Reheating

The best way to reheat this soup is gently on the stovetop over medium-low heat, stirring occasionally to distribute heat evenly. Avoid boiling it again, as this might cause the vegetables to become mushy. If reheating in a microwave, do so in short bursts, stirring between each to maintain texture. Adding a splash of vegetable broth or water during reheating helps restore its lively consistency if it thickens up.

FAQs

Can I use fresh herbs instead of dried in this recipe?

Absolutely! Fresh herbs like basil, oregano, and thyme can be used, but since they’re more delicate, I add them near the end of cooking to preserve their bright flavor. Generally, use about three times the amount of fresh herbs compared to dried.

Is this soup suitable for freezing?

Yes, this soup freezes wonderfully. Just be sure to cool it completely before freezing, and use freezer-safe containers. When you reheat, do it slowly to keep the vegetables from becoming mushy.

Can I make this soup in a slow cooker?

Definitely! Add all the chopped vegetables, broth, tomatoes, and seasonings to your slow cooker and cook on low for 4 to 6 hours. Add delicate greens, peas, and fresh herbs about 15 minutes before serving to avoid overcooking.

How can I add protein to this vegetable soup?

I like tossing in cooked beans like chickpeas or lentils for a plant-based protein boost. Alternatively, shredded cooked chicken or turkey can be stirred in if you’re not keeping it vegetarian.

What bread pairs best with this soup?

I recommend a crusty sourdough or a warm garlic baguette. The chewy, crunchy texture of the bread is perfect for dipping into the flavorful broth and balances the tender veggies in the soup.
