For many, broccoli cheddar soup stands as a timeless symbol of cozy indulgence. Its rich, cheesy texture and savory flavor are simply irresistible. However, traditional versions of this beloved soup often come loaded with hidden carbs, primarily from flour-based thickeners, making them a challenging choice for those following a ketogenic or low-carb lifestyle.
But what if you could enjoy all the creamy, cheesy goodness without derailing your health goals? What if you could whip up a restaurant-quality bowl of low-carb broccoli cheddar soup in under 30 minutes?

Thanks to the efficiency of the Instant Pot, you can transform simple, wholesome ingredients into a decadent, velvety soup that’s perfect for busy weeknights or relaxed weekend meals. This recipe is designed to become your new fall favorite, offering both the speed of pressure cooking and the option for a classic stovetop preparation. Prepare to be amazed by how incredibly rich and flavorful a low-carb, cauliflower-thickened soup can be!
The Secret to Sensationally Thick & Low-Carb Broccoli Cheese Soup
The brilliance of this Keto Broccoli Cheddar Soup lies in its ingenious approach to achieving that luxurious, thick consistency without relying on high-carb flours or starches. Instead, we harness the power of a humble vegetable: cauliflower. By transforming frozen cauliflower rice into a silky-smooth puree, we create a natural, nutrient-dense thickener that seamlessly blends into the soup, adding body and depth without compromising on flavor or nutritional values.
This method not only keeps the soup firmly in keto territory but also makes it naturally gluten-free and grain-free. The subtle flavor of cauliflower rice melts away into the rich broth, enhancing the savory notes of the cheddar and broccoli rather than overpowering them. This technique is a true revelation for anyone seeking healthy, low-carb alternatives to their favorite comfort foods.
Key Ingredients for a Perfectly Creamy Instant Pot Keto Broccoli Cheddar Soup
Our Instant Pot Keto Broccoli Cheddar Soup relies on a selection of simple, high-quality ingredients to achieve its remarkable flavor and texture. Each component plays a crucial role in creating a balanced and deeply satisfying meal. Here’s a closer look at what you’ll need:
- Grass-Fed Butter: The foundation of our soup, butter provides a rich, savory base for sautéing the aromatics. Opting for grass-fed butter enhances the flavor and offers additional nutritional benefits.
- Yellow Onion & Garlic: These classic aromatics are essential for building a deep, complex flavor profile. Sautéing them until soft and fragrant releases their sweet and pungent notes, creating a delicious backdrop for the other ingredients.
- Fresh or Frozen Broccoli: The star of the show! Whether you choose fresh florets and stems chopped into bite-sized pieces or opt for the convenience of frozen broccoli, this vegetable is packed with nutrients and provides that signature texture. See our notes below for tips on using frozen broccoli for the best results.
- Grated Carrots: A small amount of grated carrot adds a touch of natural sweetness and a hint of vibrant color, without significantly impacting the carb count.
- Quality Chicken Stock (or Bone Broth): The liquid base of our soup. Using a high-quality chicken stock or homemade bone broth will significantly elevate the overall flavor. Bone broth, in particular, adds a boost of collagen and nutrients.
- Heavy Cream: For unparalleled richness and creaminess. Heavy cream is a keto staple that provides healthy fats and a velvety mouthfeel.
- Frozen Cauliflower Rice: Our secret weapon for thickening! Thawed and thoroughly squeezed, pureed cauliflower rice creates a smooth, flour-free base that gives the soup its luxurious body. Do not skip the squeezing step—it’s vital for consistency!
- Sharp Cheddar Cheese: The defining flavor of our soup. We recommend a high-quality, organic, pasture-raised sharp white cheddar for a robust, tangy, and authentic taste. Grating your own cheese ensures a smoother melt.
- Kosher Salt & Freshly Ground Black Pepper: To season to perfection. Adjust to your personal preference.
The Instant Pot Advantage: Speed and Flavor Infusion
The Instant Pot truly shines in this recipe, transforming a classic comfort food into a weeknight-friendly meal. The pressure cooking method allows the broccoli and carrots to become perfectly tender in just one minute of cook time (after the pot comes to pressure), locking in their nutrients and infusing the stock with their natural flavors. This rapid cooking time is pure magic, allowing you to enjoy a homemade, wholesome soup without spending hours in the kitchen. The sauté function also means you can do all your initial flavor building in one pot, minimizing cleanup – a true blessing!
Choosing Your Cheese: The Heart of Broccoli Cheddar Soup
After the vegetables have cooked to tender perfection and the creamy cauliflower puree has been stirred in, the final and perhaps most crucial step is adding the cheese. The choice of cheese profoundly impacts the soup’s character. We highly recommend using an organic, pasture-raised sharp white cheddar. Brands like Rumiano, often found at quality grocery stores like Sprouts, offer excellent options that provide a robust and authentic cheddar flavor.
A sharp cheddar is preferred because it delivers an intense burst of cheesy goodness that permeates every spoonful. While yellow cheddar is traditional, a white cheddar often results in a more visually appealing soup with a more natural, subtle color. However, feel free to use your favorite variety of cheddar – whether it’s mild, medium, or extra sharp, or even a blend of cheeses – to customize the flavor to your liking. Just ensure it’s a good melting cheese for that ultimate creamy consistency.

Ingredients
- 2 tablespoons grass-fed butter
- 1 yellow onion, chopped
- 4 cloves of garlic, grated or finely chopped
- 4 cups raw broccoli, florets and stems chopped into bite-sized pieces
- 1 cup grated carrot
- 4 cups chicken stock, divided
- 1 cup heavy cream
- 2 10-ounce bags frozen cauliflower rice, thawed
- 8 ounces sharp cheddar cheese, grated
- kosher salt + pepper to taste
Instructions
-
Set your Instant Pot to SAUTE mode. Add the 2 tablespoons of grass-fed butter and the chopped yellow onion. Sauté for about 5 minutes, stirring occasionally, until the onion is soft and translucent. Stir in the grated or finely chopped garlic and continue to cook for another 30 seconds until fragrant, being careful not to burn it.
-
Add the 4 cups of chopped raw broccoli, 1 cup of grated carrots, and 3 cups of chicken stock to the Instant Pot. Stir everything to combine the ingredients evenly.
-
Secure the lid on the Instant Pot and ensure the vent is set to the SEALING position. Press CANCEL on the Instant Pot, then select HIGH PRESSURE and set the timer for 1 minute. It will take approximately 5 minutes for the pot to reach pressure before the 1-minute cooking cycle begins. Once the cooking is complete, allow a NATURAL RELEASE for 5 minutes. After 5 minutes, carefully perform a QUICK RELEASE by moving the valve to VENTING to release any remaining steam. Once all the steam has dissipated and the float valve has dropped, you can safely open the Instant Pot.
-
While the soup is cooking, thoroughly squeeze all the excess water out of the thawed cauliflower rice. This is a crucial step for a thick soup! You can use a nut milk bag, several layers of cheesecloth, or clean kitchen towels to press out as much moisture as possible. You’ll be surprised by how much water comes out!
-
In a high-speed blender, combine the squeezed cauliflower rice, the remaining 1 cup of chicken stock, and 1 cup of heavy cream. Blend on high speed until the mixture is completely smooth and forms a thick, uniform puree.
-
Carefully add the cauliflower puree to the Instant Pot with the cooked broccoli and carrots. Stir well to fully incorporate the puree into the soup base.
-
Add the 8 ounces of grated sharp cheddar cheese to the soup. Stir continuously until the cheese has completely melted and the soup is smooth and creamy.
-
Season the soup generously with kosher salt and freshly ground black pepper to taste. Adjust seasoning as needed for your desired flavor.
-
Serve your delicious Instant Pot Keto Broccoli Cheddar Soup warm, perhaps with a sprinkle of extra cheese or fresh herbs. Enjoy!
-
Store any leftover soup in an airtight container in the refrigerator for up to 5 days, or freeze for up to 6 months for a convenient meal later.
Helpful Notes and Adaptations
Broth/Stock Selection: The quality of your broth significantly impacts the soup’s flavor. You can use any chicken stock, vegetable stock, or chicken/vegetable broth. For the richest flavor and added nutrients, we highly recommend using homemade bone broth. The higher the quality, the more flavorful your soup will be!
Dairy-Free & Whole30 Modifications: To make this soup dairy-free and Whole30 compliant, you’ll need to make a few substitutions. Replace the grass-fed butter with ghee. Substitute the heavy cream with our homemade cashew cream for a rich, creamy texture. Omit the cheddar cheese entirely. To replicate a “cheesy” flavor, you can add about ¼ cup of nutritional yeast during the final step.
Using Frozen Broccoli: Frozen broccoli florets work perfectly in this recipe. We recommend thawing them first. Gently press the thawed florets in a strainer or with paper towels to remove as much excess moisture as possible. Too much water from frozen broccoli can thin out the soup, affecting its desired creamy consistency.
Frozen Cauliflower Rice vs. Fresh: For convenience and optimal texture, we highly recommend using thawed frozen cauliflower rice over fresh. If using fresh cauliflower, you would need to steam it first before blending, which adds an extra step. Remember, whether fresh or frozen, *do not skip* the critical step of squeezing all the moisture out of the thawed cauliflower rice before blending. This is paramount for achieving a thick, non-watery soup. Trust us, we’ve learned this the hard way!
Reheating Instructions: Leftover soup can be easily reheated. Microwave individual portions until warm, usually about 2-3 minutes, stirring halfway through. Alternatively, gently reheat the soup in a pot on your stovetop over medium heat, stirring occasionally until heated through.
Serving Suggestions and Pairing
This Instant Pot Keto Broccoli Cheddar Soup is a meal in itself, rich and satisfying. However, you can enhance your dining experience by pairing it with complementary low-carb options. A simple side salad with a vinaigrette dressing would provide a refreshing contrast. For those who miss bread with their soup, consider serving it with slices of keto-friendly bread or crispy cheese crisps. A dollop of sour cream or a sprinkle of fresh chives or bacon bits can add an extra layer of flavor and texture as a garnish.
