There’s something about a pot of homemade vegetable soup simmering on the stove that makes a kitchen feel alive. Steam curls up from the pot, carrying whispers of garlic and tomato. The broth turns golden as potatoes soften and release their starch. This isn’t fancy cooking—it’s the kind of soup that fills bowls on Tuesday nights when you need something warm and real. Homemade vegetable soup comes together in 45 minutes with ingredients you probably have on hand. No fancy techniques. Just good vegetables, a solid broth, and heat that coaxes everything into something better than the sum of its parts.

Key Ingredients
Olive oil starts the whole thing. Two tablespoons heat until they shimmer, creating the fat base that’ll carry flavor through every spoonful.
Onion, carrot, and celery form the aromatic trinity. This isn’t mirepoix (that’s French and uses different ratios), but it works the same magic—building a savory foundation. Dice them roughly the same size so they cook evenly. The onion sweetens, the carrot adds earthiness, the celery brings a subtle bitterness that balances everything.
Garlic goes in with the aromatics, not before. Four cloves minced fine. If you add it too early, it burns and turns bitter. Wait until the vegetables have softened.
Yukon Gold potatoes matter here. They hold their shape better than russets and add a buttery quality to the broth as they cook. Peel them (the skins get weird in soup) and cut into half-inch cubes. Uniform size means they’ll all finish at the same time.
Fire-roasted tomatoes bring smoky depth you can’t get from regular canned tomatoes. Keep every drop of that juice—it’s packed with flavor. One 14.5-ounce can is enough to tint the broth without overwhelming it.
Vegetable broth is your liquid backbone. Eight cups sounds like a lot, but it’s a generous soup. Use good broth. The cheap stuff tastes like salted water. If you’ve got homemade, even better.
Italian seasoning is the lazy cook’s herb blend, and I mean that as a compliment. One teaspoon gives you basil, oregano, thyme, and rosemary without opening four jars.
Zucchini goes in later because it cooks fast. Quarter it lengthwise, then slice. You want pieces that fit on a spoon but still have some presence.
Frozen corn and peas are underrated. They’re picked and frozen at peak sweetness. One cup each, thawed. They need maybe five minutes to heat through.
Instructions
Set your 4-quart soup pot over medium heat. Add the olive oil and watch it. When it shimmers and moves easily across the bottom, it’s ready. Too cool and your vegetables steam instead of sauté. Too hot and the garlic will scorch later.
Drop in the diced onion, carrot, celery, and minced garlic. Stir them around so everything gets coated in oil. Let them cook about five minutes, stirring every minute or so. You’ll smell the change—raw onion sharpness mellows into something sweet. The vegetables soften but shouldn’t brown. If they start catching, lower your heat a notch.
Add the diced potatoes, fire-roasted tomatoes with all their juice, vegetable broth, Italian seasoning, salt, and pepper. Stir everything together. The potatoes will sink, the tomatoes will float. That’s fine. Put the lid on loosely—you want steam to escape or the pot might boil over.
Turn the heat up to bring everything to a boil. You’ll see big bubbles breaking the surface. Once it’s boiling, reduce the heat to maintain a gentle simmer. Those small, lazy bubbles that barely disturb the surface. Set a timer for 8 minutes.
Check a potato cube with a fork. It should pierce easily but not fall apart. If it’s still firm in the center, give it another 2 minutes. This is your texture checkpoint—undercooked potatoes are unpleasant, mushy ones disappear into the broth.
Stir in the zucchini, corn, and peas. The temperature will drop when you add them, but it’ll come back up quickly. Simmer another 5 minutes. The zucchini should be tender but still hold its shape. The corn and peas just need to heat through.
Taste the broth. This is critical. Add more salt if it tastes flat. Grind in more pepper if it needs bite. The difference between good soup and great soup is often just another quarter-teaspoon of salt.
Ladle into bowls while it’s hot. Squeeze lemon over the top if you want brightness. Scatter chopped parsley if you’ve got it. The acid from the lemon wakes everything up.
For storage, let the soup cool completely before transferring to containers. Hot soup in a sealed container creates condensation, which leads to faster spoilage. It’ll keep in the fridge for five days, or freeze it for up to three months.
Tips & Variations
Cut vegetables uniformly. Sounds basic, but it matters. When your carrot chunks are twice the size of your celery, they finish cooking at different times. Aim for half-inch pieces across the board.
Don’t skip the sauté step. Those first five minutes of cooking the aromatics in oil develop flavor you can’t get by just dumping everything in broth. The heat caramelizes natural sugars and releases aromatic compounds. It’s the difference between flat soup and one with depth.
Add greens at the end. Spinach or kale work beautifully here. Stir in two cups of roughly chopped greens during the last 2 minutes. They’ll wilt into the soup and add color.
Make it creamy by blending half the soup once it’s done, then stirring it back in. You get body without adding cream.
Try different vegetables based on season. Green beans instead of peas. Butternut squash instead of potatoes. Fennel instead of celery.
Storage & Pairings
Refrigerate in airtight containers for up to five days. The flavors actually improve overnight as everything melds. Freeze in portion-sized containers for up to three months. Thaw in the fridge overnight, then reheat gently on the stove.
Serve with crusty bread for dipping, grilled cheese sandwiches, or a simple side salad. The soup’s hearty enough to stand alone but pairs well with something crunchy.
FAQ
Can I use chicken broth instead of vegetable broth?
Yes. The soup won’t be vegetarian anymore, but chicken broth works fine. It’ll taste slightly richer and less clean than vegetable broth. Use the same amount—eight cups.
Why is my soup watery?
Two common reasons: too much broth or not enough simmering time. If it’s thin, simmer uncovered for 10 more minutes to reduce the liquid. The potatoes will also release starch as they cook, which naturally thickens the broth. Next time, start with seven cups of broth and add more if needed.
