I stumbled onto this recipe during my first winter doing keto—desperate for comfort food that wouldn’t kick me out of ketosis. Now?

Ingredients for Low-Carb Broccoli Cheddar Soup

Okay, let’s gather our kitchen squad! This soup keeps it simple, but every ingredient plays a starring role. I’ll tell you exactly how I prep them—because yes, the way you chop that broccoli or shred that cheese matters for the best texture. Here’s what you’ll need:

• 4 cups chopped broccoli – Florets and tender stems (chop ’em small for quicker cooking!)
• 2 cups shredded sharp cheddar cheese – Hand-shredded, please! Pre-shredded bags have anti-caking agents that make the soup grainy.
• 1/2 cup heavy cream – The richer, the better. This is where the velvet texture comes from.
• 2 cups chicken broth – Homemade or low-sodium store-bought (you control the salt!).
• 1/2 yellow onion, finely diced – About the size of a tennis ball before chopping.
• 2 cloves garlic, minced – Fresh is key here—no jarred stuff for this superstar flavor.
• 2 tbsp butter – Salted or unsalted both work (I use salted for extra oomph).
• Salt and black pepper – To taste, but don’t skimp—cheese needs seasoning too!

Pro tip: Set your cheese and cream on the counter while prepping other ingredients. Room-temp dairy melts like a dream and won’t shock the soup into curdling. So simple, so genius!

How to Make Low-Carb Broccoli Cheddar Soup

Alright, let’s turn these ingredients into magic! I’ve made this soup more times than I can count, and I’ve learned a few tricks to avoid common pitfalls (like grainy cheese or overcooked broccoli). Follow these steps, and you’ll have a velvety, dreamy bowl of comfort in no time.

Sauté the Aromatics

First, grab your favorite soup pot—something heavy-bottomed to distribute heat evenly. Melt that butter over medium heat (no higher, or the garlic will burn and turn bitter!). When it’s just starting to foam, toss in your diced onions. Stir them around for about 3 minutes until they turn translucent and smell sweet. Now add the minced garlic and stir for just 30 seconds—garlic cooks fast, and burnt garlic is the enemy of good soup!

Simmer the Broth and Broccoli

Pour in the chicken broth and crank the heat up to medium-high until it starts bubbling. Now add your chopped broccoli—stems and all!—and give it a good stir. Lower the heat to a gentle simmer, pop on the lid, and let it cook for 8–10 minutes. You want the broccoli tender but still bright green (nobody likes mushy, gray broccoli). Poke a fork into a floret to test—it should slide in easily but still have a tiny bit of firmness.

Add Cream and Cheese

Here’s where patience pays off: reduce the heat to low before adding the heavy cream. Stir it in gently, then let the soup warm through for 2 minutes—this keeps the cream from curdling. Now, sprinkle in your shredded cheddar a handful at a time, stirring constantly until each addition melts before adding more. This slow-and-steady method prevents clumping and ensures silky smoothness. If the soup seems too thick, add a splash of broth or water to loosen it up.

Blend for Smoothness (Optional)

Prefer a smoother soup? Grab an immersion blender and pulse a few times right in the pot (careful of splatters—tilt the pot slightly away from you). No immersion blender? Let the soup cool slightly, then blend in batches in a countertop blender, filling only halfway and holding the lid firmly with a towel (hot soup expands!). Want some texture? Blend half and leave the rest chunky—best of both worlds!

Pro tip: Taste and adjust seasoning at the end—cheddar varies in saltiness, so you might need an extra pinch of salt or pepper. Trust your taste buds!

Tips for the Best Low-Carb Broccoli Cheddar Soup

After making this soup more times than I can count (seriously, my pot probably has permanent cheese stains), I’ve picked up a few game-changing tricks:

• Shred your own cheese – That pre-shredded stuff? It’s coated in weird powders that make your soup grainy. A block of sharp cheddar and 2 minutes with a grater makes all the difference.
• Save some crunch – Before blending, fish out a few broccoli florets to stir back in later. That little texture surprise is *chef’s kiss*.
• Low and slow with the cheese – Dump it all in at once and you’ll get a clumpy mess. Add it gradually like you’re sprinkling fairy dust!
• Broth temperature matters – If your soup’s too hot when adding cream, it might separate. Let it cool just slightly off the boil first.

Trust me—these tiny tweaks take this soup from “good” to “lick-the-bowl-clean” status!

Variations on Low-Carb Broccoli Cheddar Soup

Listen—I love the classic version, but sometimes you gotta mix it up! Here are my favorite twists:

• Cauliflower power: Swap half the broccoli for cauliflower florets. It blends up extra creamy and sneaks in more veggies.
• Bacon bomb: Top bowls with crispy crumbled bacon (because everything’s better with bacon, right?).
• Spicy kick: Stir in a pinch of cayenne or a diced jalapeño with the onions for a warm tingle.
• Dairy-light: Use almond milk instead of heavy cream—just add an extra handful of cheese to keep it rich.

See? Endless cozy possibilities!

Serving Suggestions

Oh, the joy of ladling this soup into bowls! My family loves it with buttery keto crackers for dunking or a crisp side salad with lemon dressing to cut the richness. For extra fun, serve it in bread bowls (just scoop out the insides for a carb-conscious version!).

Storing and Reheating Low-Carb Broccoli Cheddar Soup

This soup reheats like a dream—if you do it right! Let it cool completely before tucking it into airtight containers (I swear by mason jars for portion control). It’ll keep fresh in the fridge for 3 days, but good luck not eating it all sooner! When reheating, go low and slow—warm it gently on the stove over medium-low heat, stirring often to prevent the cheese from separating. A splash of broth or cream revives the silky texture if needed. Pro tip: Never microwave on high—those hot spots turn creamy soup into a grainy mess!

Nutritional Information

Now, I’m no nutritionist, but I can tell you this soup plays nice with low-carb lifestyles! Keep in mind these numbers are ballpark figures—your exact counts will dance around depending on your cheese brand, how much broth you use, or whether you go wild with extra toppings (looking at you, bacon lovers).

The magic happens when you realize this isn’t some sad “diet” soup. It’s packed with good fats from the cream and cheese to keep you satisfied, and all that broccoli means you’re getting fiber and nutrients too. Just remember—nutrition labels vary, so if you’re tracking macros closely, always check your specific ingredients. But honestly? When it tastes this good, sometimes you just gotta enjoy the cheesy bliss without overthinking it!

Frequently Asked Questions

I get it—when you’re whipping up a new recipe, little questions pop up! Here are the answers to the ones I hear most about this Low-Carb Broccoli Cheddar Soup (plus a few troubleshooting tips I’ve learned the hard way).

Can I freeze this soup?
Technically? Yes. Emotionally? It’s risky. Dairy-based soups can separate when thawed, giving you a grainy texture. If you must freeze it, skip the cream and add it fresh when reheating. Better yet, just halve the recipe—it’s so quick to make fresh!

Is almond milk a good substitute for heavy cream?
For a lighter version, sure! Use unsweetened almond milk, but know it’ll be thinner. I bump up the cheese by 1/4 cup to compensate for richness. Cashew milk works even better—its natural creaminess mimics heavy cream beautifully.

Why did my cheese turn stringy or clumpy?
Ah, the heartbreak of broken cheese sauce! Usually it means the soup was too hot when you added the cheese. Next time, take the pot off the heat for 2 minutes before stirring in the cheddar. And always shred your own—those pre-shredded bags have weird coatings that resist melting smoothly.

Can I make this soup in a slow cooker?
Absolutely! Sauté the onions and garlic first (trust me, it’s worth the extra pan), then dump everything except the cream and cheese into the slow cooker. Cook on low for 3–4 hours. Stir in the cream and cheese right before serving so they stay velvety.

My soup is too thin—how do I thicken it?
No flour? No problem! Try blending half the soup to create natural thickness from the broccoli. Or sprinkle in a little xanthan gum (a keto thickener)—start with 1/8 teaspoon and whisk like crazy. My favorite trick? Simmer uncovered for 5 extra minutes to reduce the liquid. Easy peasy!
