Low-Calorie Broccoli Soup
There’s something so comforting about a big bowl of broccoli soup, especially when it’s blended up silky smooth and doesn’t weigh you down. This one’s been in my regular rotation for years because it tastes like a treat but barely makes a dent in your day. If you need something warm, green, and satisfying without any of the guilt, this is it.
Why You’ll Love This Recipe

This soup comes together in under 30 minutes, which makes it perfect for busy weeknights when you still want something homemade. It’s naturally low in calories but doesn’t skimp on flavor, thanks to garlic, onion, and a good hit of black pepper. Plus it’s endlessly flexible, so you can dress it up with toppings or keep it simple depending on your mood.
I also love that it’s one of those recipes where you basically just chop, simmer, and blend. No fancy technique required, and you probably already have most of the ingredients sitting in your fridge right now.
Ingredients You’ll Need

Broccoli is obviously the star here, and you’ll want fresh florets if you can get them, though frozen works in a pinch. Onion and garlic build the savory base, and a little olive oil helps everything soften up nicely before you add liquid. For the broth, a low-sodium vegetable or chicken stock keeps things light while still giving you plenty of flavor.
A splash of milk or a spoonful of plain Greek yogurt at the end adds creaminess without loading up on calories the way heavy cream would. If you want it fully dairy-free, a splash of unsweetened almond milk works surprisingly well too. Salt and pepper are your main seasonings, but a pinch of nutmeg is a nice little secret if you have it on hand.
Tips for the Best Results

Let the soup cool for a few minutes before blending if you’re using a regular blender, since hot liquid can cause pressure to build up and make a mess. If you have an immersion blender, you can skip this step entirely and blend right in the pot, which saves on dishes too.
Taste as you go and adjust the seasoning at the end, since broth brands vary a lot in saltiness. A squeeze of lemon juice right before serving also brightens everything up in a way that’s hard to explain until you try it.
Storage and Reheating

This soup keeps beautifully in the fridge for up to 4 days in an airtight container. It also freezes really well, so I like making a double batch and freezing half in individual portions for easy lunches later.
Frequently Asked Questions

Can I make this soup without a blender?
You can mash the broccoli with a potato masher for a chunkier, more rustic texture. It won’t be as silky smooth, but it’s still delicious and saves you a step.
Is this soup keto-friendly?
Yes, it’s naturally low in carbs, especially if you use the yogurt or milk in small amounts. Just double check your broth for any hidden sugars.
Can I add protein to make it a full meal?
Shredded chicken, white beans, or a poached egg on top all work great here. It turns this from a starter soup into something you can eat as a main.
Why does my soup taste bland?
It usually just needs more salt than you’d expect, since broccoli itself is fairly mild. A splash of lemon juice or a sprinkle of parmesan can also wake up the flavor fast.
