Sautéing Aromatics for the Keto Broccoli Cheese Soup Base
First things first, grab a nice big pot – your favorite soup pot will do! Pop it on the stove over medium heat and let that tablespoon of olive oil get nice and warm. Toss in your chopped onion and let it soften up for about 5 minutes. You want it to be nice and tender, not browned. Then, add your minced garlic and cook for just another minute until you can really smell that amazing garlicky aroma. Be careful not to burn it!
Simmering Broccoli and Broth for Flavor
Now it’s time for the broccoli! Add your fresh florets and the chicken broth to the pot. Give it a good stir. We want to bring this mixture up to a boil, but once it’s bubbling, turn the heat down to low. Let it simmer away gently for about 10 to 15 minutes, or until your broccoli is fork-tender. You want it soft enough to blend easily.
Blending for a Smooth Keto Broccoli Cheese Soup
This is where we get that super smooth, velvety texture we’re after! You have two choices here: carefully ladle the hot soup into a standing blender or, my personal favorite, use an immersion blender right in the pot. Whichever you choose, blend until everything is smooth and creamy. Just be extra careful if you’re using a regular blender – hot liquids can expand, so don’t fill it up too much and hold that lid down tight!
Melting Cheese and Finishing the Soup
Once it’s all blended and back in the pot (if you used an immersion blender, you can skip that part!), stir in your heavy cream. Oh yeah, here comes the magic! Add the shredded cheddar cheese, salt, and pepper. Now, you need to heat this GENTLY. Keep the heat on low and stir constantly. You want that cheese to melt perfectly into the soup, making it rich and luscious. The most important thing here is DO NOT BOIL the soup after you add the cheese. Just let it heat through until everything is melted and gorgeous. Trust me on this one! Looking for another incredible broccoli cheese recipe? You might love this Broccoli Cheddar Soup!

Tips for the Best Keto Broccoli Cheese Soup
Making this Keto Broccoli Cheese Soup is pretty foolproof, but here are a few of my top secrets to make it absolutely perfect every single time. I’ve learned a thing or two over the years, and these little tweaks really make a difference! Oh, and if you love broccoli and cheese, my Broccoli Cheese Casserole is another keeper!
- Fresh is Best for Broccoli: While frozen broccoli can work in a pinch, using fresh florets gives you the brightest flavor and best texture.
- Don’t Boil the Cheese: Seriously, this is key! Once you add the cheese and cream, keep the heat low and stir constantly. Boiling can make the soup grainy or separate. We want velvety smooth, remember?
- Adjust Consistency: If your soup is too thick, just stir in a little more chicken broth or even a splash of almond milk. Too thin? Let it simmer gently for a few more minutes without the lid, or add a tiny bit more cheese.
- Seasoning is Queen: Taste and adjust your salt and pepper at the end. Sometimes the broth is salty enough, and you might want a bit more pepper to give it a kick.
Ingredient Notes and Substitutions for Keto Broccoli Cheese Soup
Okay, let’s talk ingredients! Sometimes you might not have exactly what’s called for, or maybe you need to swap something out. No worries, this Keto Broccoli Cheese Soup is pretty flexible. For instance, if you’re out of chicken broth, a good quality vegetable broth works just fine, though it might change the flavor profile a tiny bit. If you’re in a pinch and don’t have heavy cream, half-and-half will do, but your soup won’t be quite as luxuriously creamy. You could even try unsweetened almond milk, but that might make it a bit thinner, so you’d definitely want to add that extra bit of cheese! Speaking of cheese, sharp cheddar gives the best flavor, but a mix of cheddar and Monterey Jack is delicious, too. For more hearty soup ideas, check out my Creamy Chicken Soup!

Serving Suggestions for Your Keto Broccoli Cheese Soup
Now that you’ve got this piping hot bowl of Keto Broccoli Cheese Soup, what do you pair it with? To keep things keto-friendly, I love serving it alongside a crisp Caesar Salad with a homemade creamy dressing. It’s the perfect fresh contrast! Another great option is some keto-friendly crackers or a slice of almond flour bread if you’re feeling ambitious. Either way, this soup is hearty enough to be a meal on its own!

Storage and Reheating Instructions
Leftover Keto Broccoli Cheese Soup is a gift that keeps on giving! Once it’s cooled down a bit, just pop it into an airtight container and stash it in the fridge. It’ll keep wonderfully for about 3 to 4 days. When you’re ready for another bowl, the best way to reheat is gently on the stovetop over low heat, stirring often. Pop it in a saucepan, add a tiny splash of broth or cream if it seems a bit thick, and just let it warm through. Please, please, please don’t boil it – we don’t want to mess with that beautiful creamy texture!
Frequently Asked Questions about Keto Broccoli Cheese Soup
Got questions about our amazing Keto Broccoli Cheese Soup? I’ve got answers! I’ve heard a few things pop up when people start making it, and I’m happy to clear them up. This soup is definitely a keto favorite for good reason!
Is this broccoli cheese soup really keto-friendly?
Absolutely! This recipe is specifically designed to be low in carbohydrates. We use heavy cream and cheese for that luscious texture and flavor, and skip high-carb ingredients like flour or potatoes. So yes, you can totally enjoy this comforting soup while sticking to your keto goals. Looking for other low-carb favorites? You might want to check out my Broccoli Rice Bake!
How can I make this soup thicker if I like it really hearty?
Great question! If you prefer a thicker soup, you’ve got a couple of easy options. You can simply use a little less chicken broth when you’re simmering the broccoli, or stir in a bit more shredded cheddar cheese at the end. Cheese is a fantastic natural thickener, especially when melted slowly! You could also let it simmer uncovered for a few extra minutes after blending, but watch it closely so it doesn’t get too thick.
Can I make this recipe dairy-free or lactose-free?
This is a bit trickier since it’s *cheese* soup, right? Making it fully dairy-free would change it quite a bit, but you could try substituting the heavy cream with full-fat unsweetened coconut milk or a good quality unsweetened dairy-free creamer. For the cheese, there are some dairy-free cheddar alternatives available, but their melting and flavor properties can vary wildly. It might not be as creamy or cheesy, but it’s worth a shot if you have dietary restrictions!
What kind of cheddar cheese is best for this soup?
Honestly, I find that a sharp or extra-sharp cheddar gives the best flavor! Since we’re using cheese as a flavor powerhouse in this keto soup, a sharper cheese really shines through. Plus, the real stuff melts so much better than pre-shredded cheese that often has anti-caking agents. Grate it yourself from a block for the smoothest, creamiest results!
