When it comes to hearty soups and stews, nothing quite curbs my craving like a massive bowl of broccoli cheddar soup.
Of course, being keto means I have to sacrifice–but not when it comes to this recipe. Made with tender broccoli and an ultra-creamy broth, the word “compromise” has no meaning here.

Why I love this recipe
- Everyone (yes, everyone!) will love it. Make this for the whole family, and I guarantee even the carb-lovers will be coming back for seconds or thirds.
- Made in one pot. So clean-up is done in minutes.
- Ready in 30 minutes. So you can whip this up on a hectic weeknight.
- Multiple cooking methods included. I think the stovetop method yields the best results, but I tested this recipe on the Instant Pot and slow cooker, too.
Ingredients needed
- Butter. I prefer unsalted butter since we’re adding salt to the soup.
- Onion and garlic. Essential aromatics for any good soup.
- Chicken broth. Homemade or store-bought. If you go the store-bought route, make sure it doesn’t have any added sugar. Use vegetable broth to make this soup vegetarian-friendly.
- Heavy cream. Gives the soup an extra rich and creamy texture without affecting the flavor. For even creamier soup, you can use softened cream cheese.
- Fresh broccoli. Finely chopped broccoli. Avoid using frozen broccoli, as it will yield a thinner soup.
- Smoked paprika. Adds some smokey flavor that complements the cheese.
- Salt and pepper. To taste.
- Cheddar cheese. The highlight of this soup is the cheese, and I prefer freshly grated cheddar because it’s salty and easy to melt. If you want a more intense cheese flavor, swap half of the cheddar cheese for vintage or extra sharp cheddar.
- Parsley. Optional, for garnish.
How to make keto broccoli cheese soup
I’ve included step-by-step photos below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the recipe card at the bottom of this post.
Step 1- Cook onions and garlic. Add butter to a large pot over medium heat. Once hot, add the onions and garlic and stir fry for 1-2 minutes.
Step 2- Build the soup. Add all of the ingredients except for the cheese and bring to a boil. Once boiling, reduce the heat to low and simmer for 20 minutes or until the broccoli is tender.
Step 3- Add the cheese. Add the cheese half a cup at a time until combined. Remove from the heat and serve with extra cheese and parsley on top.
Alternative cooking methods
While I prefer the stovetop, if you’d rather make keto broccoli soup using a pressure cooker or slow cooker, you certainly can. Here’s how:
Instant pot method. Turn the Instant Pot to Sauté and add the butter and aromatics. Sauté for a few minutes, then add the rest of the ingredients (except the cheese). Cook on Manual/Pressure Cook mode for 8 minutes, then natural pressure release for 5 minutes. Slowly stir in the cheese until combined.
Slow cooker method. Omit the butter and the ingredients (except the cheese) into the slow cooker. Cook on low for 6 hours. After 6 hours, slowly add the cheese, cover the pot, and cook for 30 minutes.
Arman’s recipe tips
- Chop the broccoli into bite-sized pieces. So they cook evenly.
- Add the cheese a little at a time. Don’t rush it! If you add the cheese too quickly, it’ll clump up and become grainy.
- Shred your own cheese. I hinted at this earlier, but it bears repeating. Shredding cheese from a block makes for smoother cheese that melts (and tastes) much better than pre-shredded cheese.
Variations
- Thicken the soup. If you want your soup to be extra thick, you have options. Either add ½ teaspoon of xanthan gum or 1-2 tablespoons of arrowroot powder. Just note that arrowroot powder will increase the carb count slightly.
- Or blend it instead. This soup is designed to have chunks of broccoli throughout, but if you prefer a silky smooth soup, you can puree it using an immersion blender.
- Add extra vegetables. Bulk up the soup with low-carb veggies like cauliflower, broccoli florets, or kale.
- Toss in some protein. Like shredded rotisserie chicken, crispy bacon, or my keto meatballs.
- Add some flavor. While optional, I find a little Dijon mustard or hot sauce adds a ton of flavor.
Storage instructions
To store: Store your cooled soup in an airtight container in the refrigerator for up to 1 week.
To freeze: Let your soup cool completely, then transfer it to a freezer-safe container and freeze for up to 3 months.
Reheating: Reheat over low-medium heat. Add a splash of water or broth if the soup is too thick. You can also reheat it in the microwave.
Frequently asked questions
This soup is designed to have chunks of broccoli throughout, but if you prefer a silky smooth soup, you can either puree it (using a hand mixer) or put it in a blender.
Thicken the soup by adding 1/2 teaspoon of xanthan gum or 1-2 tablespoons of arrowroot powder. The arrowroot will add some extra carbs to the overall carb count.
This recipe yields six 1 1/2 cup servings. Each serving contains 2 grams of net carbs.

Delicious!! It tastes better than Panera!
I have made this recipe 3 times and shared with friends. We all love it. It freezes well as well. I do add slightly less cheddar cheese and only use sharp cheddar. I love this recipe. Very hearty.
Great, easy soup on a fall day. I’ve made other recipes but this is the best I’ve tried. I also add shredded carrot and their tops finally chopped. Plus a tsp of garlic chili sauce.
Thank you for sharing
I have use many of your recipes since starting my keto journey. I have never been disappointed. This is probably the best broccoli cheese soup I have ever made. Used half sharp cheddar and a mix of leftover Mexican style shredded cheese and cheddar, plus a half a block of cream cheese I needed to use up.
I went straight to the ingredients for the grocery store and read later. You don’t specify whether the broccoli is cooked or raw. So, cooked or raw? Looking forward to trying this.
Add raw and let it simmer until it is cooked.
This recipe is so easy and delicious!
We love this recipe!! It is a staple in our weekly menu. Thanks so much for this!
Love that, Julie!
