Low Calorie Veggie Soup

Low Calorie Veggie Soup

There’s something so comforting about a big pot of veggie soup simmering on the stove. This one is everything you want on a busy weeknight or a lazy Sunday — filling, nourishing, and genuinely delicious without any of the heaviness. And at under 150 calories a bowl, you can go back for seconds without a second thought.

Why You’ll Love This Recipe

First off, it’s incredibly flexible. You can use whatever vegetables you have hanging around in the fridge, and it still turns out great every single time. Wilting zucchini? Toss it in. Lonely celery stalks? Perfect. This soup is practically made for using up odds and ends.

It also comes together fast. You’re looking at maybe 15 minutes of chopping and then the pot does the rest. On a weeknight when you’re tired and don’t want to think too hard, that matters a lot.

And the flavor — don’t let the “low calorie” label fool you into thinking this is bland diet food. With a good broth, plenty of garlic, and a hit of herbs, this soup is genuinely satisfying. It tastes like something that took a lot more effort than it did.

Ingredients You’ll Need

The base of this soup is a solid vegetable broth — go for a low-sodium version so you can control the salt yourself. From there, you’re building layers of flavor with onion, garlic, and celery right at the start. These three together are basically the foundation of every good soup ever made.

For the vegetables, the classic combo here is diced carrots, zucchini, green beans, and canned diced tomatoes. The tomatoes add a lovely acidity and body to the broth without needing any cream or starch. Canned work perfectly and save you a ton of time.

A handful of baby spinach or kale stirred in at the very end adds color, nutrients, and a little heartiness. It wilts down quickly and you won’t even notice it if leafy greens aren’t your favorite — but it makes the soup feel more complete.

For seasoning, dried Italian herbs, a bay leaf, salt, pepper, and a small squeeze of lemon juice at the end are all you need. The lemon is optional but it really brightens the whole thing up. If you want a bit of heat, a pinch of red pepper flakes is a nice addition.

Feel free to swap things around. No zucchini? Try yellow squash or chopped broccoli. Want to add some protein? White beans or chickpeas blend in beautifully and keep the calorie count very reasonable. If you’re not vegetarian, a little shredded rotisserie chicken works great too.

Tips for the Best Results

Cut your vegetables to a similar size so everything cooks evenly. If your carrots are chunky and your zucchini is tiny, you’ll end up with some mushy and some underdone. Aim for roughly half-inch pieces across the board.

Let the soup simmer low and slow once everything is in the pot — at least 20 to 25 minutes. This is where all the flavors have a chance to get to know each other. A hard boil will make your vegetables fall apart and leave you with something murky.

Taste and adjust the seasoning at the end, not just at the beginning. Broth reduces slightly as it cooks and flavors concentrate, so what tasted fine at the start might need a little more salt or a squeeze of lemon by the time you’re done.

Storage and Reheating

This soup stores beautifully, which is honestly one of the best things about it. Let it cool completely, then transfer it to an airtight container and keep it in the fridge for up to five days. It actually tastes better the next day once everything has had time to meld together.

To reheat, just warm it gently on the stovetop over medium-low heat, stirring occasionally. Add a small splash of broth or water if it’s thickened up too much in the fridge — which it sometimes does, especially if you added any starchy vegetables or beans.

Frequently Asked Questions

Can I make this soup in a slow cooker?

Absolutely. Add all the ingredients except the spinach to your slow cooker and cook on low for 6 to 8 hours or high for 3 to 4 hours. Stir in the spinach or kale about 10 minutes before serving.

How do I make this soup more filling without adding a lot of calories?

Stir in a can of drained white beans or chickpeas. They add plant-based protein and fiber that keeps you full longer, and they barely change the flavor. You could also add a small amount of whole grain pasta or barley if you want something heartier.

Is this soup gluten-free?

Yes, as written this recipe is naturally gluten-free. Just double-check the label on your vegetable broth since some brands add ingredients that contain gluten. If you’re adding any pasta or grains, swap in a gluten-free version.

Can I use frozen vegetables instead of fresh?

You can, and it works really well. Frozen vegetables are picked and frozen at peak ripeness, so they’re actually a great option. You don’t even need to thaw them first — just add them straight to the pot and adjust the cooking time slightly since they’ll release a bit more water.
